The following peripheral interrupts are ORed to contribute to one interrupt in the NVIC: - USART1, USART4 - USART2, USART3 - SCTimer0/PWM, SCTimer1/PWM - BOD, WWDT - ADC end-of-sequence A interrupt, threshold crossing interrupt - ADC end-of-sequence B interrupt, overrun interrupt - Flash, EEPROM * Four programmable interrupt priority levels with hardware priority level masking. * Software interrupt generation. 8.8.2 Interrupt sources Each peripheral device has at least one interrupt line connected to the NVIC but can have several interrupt flags. Individual interrupt flags can also represent more than one interrupt source. 8.9 IOCON block The IOCON block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Connect peripherals to the appropriate pins before activating the peripheral and before enabling any related interrupt. Enabling an analog function disables the digital pad. However, the internal pull-up and pull-down resistors as well as the pin hysteresis must be disabled to obtain an accurate reading of the analog input. 8.9.1 Features * Programmable pin function. * Programmable pull-up, pull-down, or repeater mode. * All pins (except PIO0_4 and PIO0_5) are pulled up to 3.3 V (VDD = 3.3 V) if their pull-up resistor is enabled. * Programmable pseudo open-drain mode. * Programmable (on/off) 10 ns glitch filter on pins PIO0_22, PIO0_23, PIO0_11 to PIO0_16, PIO1_3, PIO1_9, PIO1_22, and PIO1_29.

All rights reserved. 24 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller LPC11U6x use accelerated GPIO functions: * GPIO registers are on the ARM Cortex M0+ IO bus for fastest possible single-cycle I/O timing, allowing GPIO toggling with rates of up to 25 MHz. * An entire port value can be written in one instruction. * Mask, set, and clear operations are supported for the entire port. 8.10.1 Features * Bit level port registers allow a single instruction to set and clear any number of bits in one write operation. * Direction control of individual bits. 8.11 Pin interrupt/pattern match engine The pin interrupt block configures up to eight pins from all digital pins for providing eight external interrupts connected to the NVIC. The pattern match engine can be used, in conjunction with software, to create complex state machines based on pin inputs. Any digital pin except pins PIO2_8 and PIO2_23 can be configured through the SYSCON block as input to the pin interrupt or pattern match engine. The registers that control the pin interrupt or pattern match engine are on the IO+ bus for fast single-cycle access. 8.11.1 Features * Pin interrupts - Up to eight pins can be selected from all digital pins except pins PIO2_8 and PIO2_23 as edge- or level-sensitive interrupt requests. Each request creates a separate interrupt in the NVIC. - Edge-sensitive interrupt pins can interrupt on rising or falling edges or both. - Level-sensitive interrupt pins can be HIGH- or LOW-active. - Pin interrupts can wake up the part from sleep mode, deep-sleep mode, and power-down mode. * Pin interrupt pattern match engine - Up to 8 pins can be selected from all digital pins except pins PIO2_8 and PIO2_23 to contribute to a boolean expression. The boolean expression consists of specified levels and/or transitions on various combinations of these pins. - Each minterm (product term) comprising the specified boolean expression can generate its own, dedicated interrupt request. - Any occurrence of a pattern match can be programmed to generate an RXEV notification to the ARM CPU as well. - The pattern match engine does not facilitate wake-up.

For each port/pin connected to one of the two the GPIO Grouped Interrupt blocks (GINT0 and GINT1), the GPIO grouped interrupt registers determine which pins are enabled to generate interrupts and w the active polarities of each of those inputs. The GPIO grouped interrupt registers also select whether the interrupt output is level or edge triggered and whether it is based on the OR or the AND of all of the enabled inputs. When the designated pattern is detected on the selected input pins, the GPIO grouped interrupt block generates an interrupt. If the part is in a power-savings mode, it first asynchronously wakes up the part prior to asserting the interrupt request. The interrupt request line can be cleared by writing a one to the interrupt status bit in the control register. 8.12.1 Features * Two group interrupts are supported to reflect two distinct interrupt patterns. * The inputs from any number of digital pins can be enabled to contribute to a combined group interrupt. * The polarity of each input enabled for the group interrupt can be configured HIGH or LOW. * Enabled interrupts can be logically combined through an OR or AND operation. * The grouped interrupts can wake up the part from sleep, deep-sleep or power-down modes. 8.13 DMA controller The DMA controller can access all memories and the USART and SSP peripherals using DMA requests. DMA transfers can also be triggered by internal events like the ADC interrupts, timer match outputs, the pin interrupts (PINT0 and PINT1) and the SCTimer DMA requests. 8.13.1 Features * 16 channels with 14 channels connected to peripheral request inputs. * DMA operations can be triggered by on-chip events or two pin interrupts.

The host controller allocates the USB bandwidth to attached devices through a token-based protocol. The bus supports hot-plugging and dynamic configuration of the devices. All transactions are initiated by the host controller. The USB interface consists of a full-speed device controller with on-chip PHY (PHYsical layer) for device functions. Remark: Configure the part in default power mode with the power profiles before using the USB (see Section 8.25.7.1 "Power profiles"). Do not use the USB when the part runs in performance, efficiency, or low-power mode. 8.14.1 Full-speed USB device controller The device controller enables 12 Mbit/s data exchange with a USB Host controller. It consists of a register interface, serial interface engine, and endpoint buffer memory. The serial interface engine decodes the USB data stream and writes data to the appropriate endpoint buffer.

USART1 to USART4 use a different register interface to achieve the same UART functionality except for modem and smart card control. Remark: USART3 and USART4 are available only on part LPC11U68JBD100. Interrupts generated by the USART1/2/3/4 peripherals can wake up the part from Deep-sleep and power-down modes if the USART is in synchronous mode, the 32 kHz mode is enabled, or the CTS interrupt is enabled.

The controller can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SSP supports full duplex transfers, with frames of 4 bit to 16 bit of data flowing from the master to the slave and from the slave to the master. In practice, often only one direction carries meaningful data. 8.17.1 Features * Maximum SSP speed of 25 Mbit/s (master) or 4.17 Mbit/s (slave) (in SSP mode) * Compatible with Motorola SPI (Serial Peripheral Interface), 4-wire Texas Instruments SSI (Serial Synchronous Interface), and National Semiconductor Microwire buses * * * * * Synchronous serial communication Master or slave operation 8-frame FIFOs for both transmit and receive 4-bit to 16-bit frame DMA support 8.18 I2C-bus serial I/O controller The LPC11U6x contain two I2C-bus controllers. The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial Clock line (SCL) and a Serial Data line (SDA). Each device is recognized by a unique address and can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the capability to both receive and send information (such as memory). Transmitters and/or receivers can operate in either master or slave mode, depending on whether the chip has to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be controlled by more than one bus master connected to it. LPC11U6x Product data sheet All information provided in this document is subject to legal disclaimers.

All rights reserved. 34 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8.24 Temperature sensor The temperature sensor transducer uses an intrinsic pn-junction diode reference and outputs a CTAT voltage (Complement To Absolute Temperature). The output voltage varies inversely with device temperature with an absolute accuracy of better than 5 C over the full temperature range (40 C to +105 C) for typical samples. The temperature sensor is approximately linear with a slight curvature. The output voltage is measured over different ranges of temperatures and fit with linear-least-square lines. After power-up and after switching the input channels of the ADC, the temperature sensor output must be allowed to settle to its stable value before it can be used as an accurate ADC input. For an accurate measurement of the temperature sensor by the ADC, the ADC must be configured in single-channel burst mode. The last value of a nine-conversion (or more) burst provides an accurate result. LPC11U6x Product data sheet All information provided in this document is subject to legal disclaimers.

The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of power to operate, which can be supplied by an external battery.

Each oscillator can be used for more than one purpose as required in a particular application. Following reset, the LPC11U6x operates from the internal RC oscillator until software switches to a different clock source. The IRC allows the system to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 10 for an overview of the LPC11U6x clock generation.

All rights reserved. 37 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8.25.3.1 Internal RC oscillator The IRC can be used as the clock source for the WDT, the USB PLL in low-speed USB applications, or as the clock that drives the system PLL and then the CPU. The nominal IRC frequency is 12 MHz. Upon power-up, any chip reset, or wake-up from Deep power-down mode, the LPC11U6x use the IRC as the clock source. Software can later switch to one of the other available clock sources. 8.25.3.2 System oscillator The system oscillator can be used as the clock source for the CPU, with or without using the PLL. Use the system oscillator to provide the clock source to USB. The system oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be boosted to a higher frequency, up to the maximum CPU operating frequency, by the system PLL. The system oscillator has a wake-up time of approximately 500 s. 8.25.3.3 WatchDog oscillator The watchdog oscillator can be used as a clock source that directly drives the CPU, the watchdog timer, or the CLKOUT pin. The watchdog oscillator nominal frequency is programmable between 9.4 kHz and 2.3 MHz. The frequency spread over processing and temperature is 40 % (see also Table 14). 8.25.3.4 RTC oscillator The low-power RTC oscillator provides a 1 Hz clock and a 1 kHz clock to the RTC and a 32 kHz clock output that can be used to obtain the main clock (see Figure 10). 8.25.4 System PLL and USB PLL The LPC11U6x contain a system PLL and a dedicated PLL for generating the 48 MHz USB clock. The system and USB PLLs are identical. The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz. To support this frequency range, an additional divider keeps the CCO within its frequency range while the PLL is providing the desired output frequency. The output divider can be set to divide by 2, 4, 8, or 16 to produce the output clock. The PLL output frequency must be lower than 100 MHz. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed following a chip reset. Software can enable the PLL later. The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 s. 8.25.5 Clock output The LPC11U6x feature a clock output function that routes the IRC oscillator, the system oscillator, the watchdog oscillator, or the main clock to an output pin.

All rights reserved. 38 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8.25.6 Wake-up process The LPC11U6x begin operation by using the 12 MHz IRC oscillator as the clock source at power-up and when awakened from Deep power-down mode. This mechanism allows chip operation to resume quickly. If the application uses the main oscillator or the PLL, software must enable these components and wait for them to stabilize. Only then can the system use the PLL and main oscillator as a clock source. 8.25.7 Power control The LPC11U6x support various power control features. There are four special modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode, and Deep power-down mode. The CPU clock rate can also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This power control mechanism allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals. This register allows fine-tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Selected peripherals have their own clock divider which provides even better power control. 8.25.7.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through simple calls to the power profile. The power configuration routine configures the LPC11U6x for one of the following power modes: * Default mode corresponding to power configuration after reset. * CPU performance mode corresponding to optimized processing capability. * Efficiency mode corresponding to optimized balance of current consumption and CPU performance. * Low-current mode corresponding to lowest power consumption. In addition, the power profile includes routines to select the optimal PLL settings for a given system clock and PLL input clock. Remark: When using the USB, configure the LPC11U6x in Default mode. 8.25.7.2 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core. In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and can generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, by memory systems and related controllers, and by internal buses.

All rights reserved. 39 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller 8.25.7.3 Deep-sleep mode In Deep-sleep mode, the LPC11U6x core is in Sleep mode and all peripheral clocks and all clock sources are off except for the IRC. The IRC output is disabled unless the IRC is selected as input to the watchdog timer. In addition, all analog blocks are shut down and the flash is in standby mode. In Deep-sleep mode, the application can keep the watchdog oscillator and the BOD circuit running for self-timed wake-up and BOD protection. The LPC11U6x can wake up from Deep-sleep mode via reset, selected GPIO pins, a watchdog timer interrupt, an interrupt generating USB port activity, an RTC interrupt, or any interrupts that the USART1 to USART4 interfaces can create in Deep-sleep mode. The USART wake-up requires the 32 kHz mode, the synchronous mode, or the CTS interrupt to be set up. Deep-sleep mode saves power and allows for short wake-up times. 8.25.7.4 Power-down mode In Power-down mode, the LPC11U6x is in Sleep mode and all peripheral clocks and all clock sources are off except for watchdog oscillator if selected. In addition, all analog blocks and the flash are shut down. In Power-down mode, the application can keep the BOD circuit running for BOD protection. The LPC11U6x can wake up from Power-down mode via reset, selected GPIO pins, a watchdog timer interrupt, an interrupt generating USB port activity, an RTC interrupt, or any interrupts that the USART1 to USART4 interfaces can create in Power-down mode. The USART wake-up requires the 32 kHz mode, the synchronous mode, or the CTS interrupt to be set up. Power-down mode reduces power consumption compared to Deep-sleep mode at the expense of longer wake-up times. 8.25.7.5 Deep power-down mode In Deep power-down mode, power is shut off to the entire chip except for the WAKEUP pin and the always-on RTC power domain. The LPC11U6x can wake up from Deep power-down mode via the WAKEUP pin or a wake-up signal generated by the RTC interrupt. The LPC11U6x can be blocked from entering Deep power-down mode by setting a lock bit in the PMU block. Blocking the Deep power-down mode enables the application to keep the watchdog timer or the BOD running at all times. If the WAKEUP pin is used in the application, an external pull-up resistor is required on the WAKEUP pin to hold it HIGH while the part is in deep power-down mode. To wake up from deep power-down mode, pull the WAKEUP pin LOW. In addition, pull the RESET pin HIGH to prevent it from floating while in Deep power-down mode. 8.26 System control 8.26.1 Reset Reset has four sources on the LPC11U6x: the RESET pin, the WatchDog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller.

All rights reserved. 40 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. The internal reset status is reflected on the RSTOUT pin. In Deep power-down mode, an external pull-up resistor is required on the RESET pin. The RESET pin is operational in active, sleep, deep-sleep, and power-down modes if the RESET function is selected in the IOCON register for pin PIO0_0 (this is the default). A LOW-going pulse as short as 50 ns executes the reset and also wakes up the part if in sleep, deep-sleep or power-down mode. The RESET pin is not functional in Deep power-down mode. 9'' 9'' 9'' 5SX UHVHW (6' QV5& */,7&+),/7(5 3,1 (6' 966 DDD Fig 12. RESET pin configuration 8.26.2 Brownout detection The LPC11U6x includes two levels for monitoring the voltage on the VDD pin. If this voltage falls below one of the selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC to cause a CPU interrupt. Alternatively, software can monitor the signal by reading a dedicated status register. Two threshold levels can be selected to cause a forced reset of the chip. 8.26.3 Code security (Code Read Protection - CRP) CRP provides different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) and In-System Programming (ISP) can be restricted. Programming a specific pattern into a dedicated flash location invokes CRP. IAP commands are not affected by the CRP. In addition, ISP entry via the PIO0_1 pin can be disabled without enabling CRP. For details, see the LPC11Uxx user manual. There are three levels of Code Read Protection: LPC11U6x Product data sheet All information provided in this document is subject to legal disclaimers.

CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors cannot be erased. 2. CRP2 disables access to the chip via the SWD and only allows full flash erase and update using a reduced set of the ISP commands. 3. Running an application with level CRP3 selected, fully disables any access to the chip via the SWD pins and the ISP. This mode effectively disables ISP override using PIO0_1 pin as well. If necessary, the application must provide a flash update mechanism using IAP calls or using a call to the reinvoke ISP command to enable flash update via the USART. CAUTION If level three Code Read Protection (CRP3) is selected, no future factory testing can be performed on the device. In addition to the three CRP levels, sampling of pin PIO0_1 for valid user code can be disabled. For details, see the LPC11U6x user manual.

Serial wire debug functions are supported in addition to a standard JTAG boundary scan. The ARM Cortex-M0+ is configured to support up to four breakpoints and two watch points. The RESET pin selects between the JTAG boundary scan (RESET = LOW) and the ARM SWD debug (RESET = HIGH). The ARM SWD debug port is disabled while the LPC11U6x is in reset. To perform boundary scan testing, follow these steps: 1. Erase any user code residing in flash. 2. Power up the part with the RESET pin pulled HIGH externally. 3. Wait for at least 250 s. 4. Pull the RESET pin LOW externally. 5. Perform boundary scan operations. 6. Once the boundary scan operations are completed, assert the TRST pin to enable the SWD debug mode, and release the RESET pin (pull HIGH). Remark: The JTAG interface cannot be used for debug purposes.

Thermal characteristics The average chip junction temperature, Tj (C), can be calculated using the following equation: T j = T amb + P D R th j - a (1) * Tamb = ambient temperature (C), * Rth(j-a) = the package junction-to-ambient thermal resistance (C/W) * PD = sum of internal and I/O power dissipation The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of the I/O pins is often small and many times can be negligible. However it can be significant in some applications. Table 7.

All rights reserved. 56 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller The power profiles optimize the chip performance for power consumption or core efficiency by controlling the flash access and core power. As shown in Figure 21 and Figure 22, different power modes result in different CoreMark scores reflecting the trade-off of efficiency and power consumption. In CPU and efficiency modes, the power profiles aim to keep the core efficiency at a maximum for the given system frequency. Depending on optimal flash access parameters that change with frequency, the CoreMark score and also the power consumption change. Since the compiled code for CoreMark testing runs out of flash memory, the CoreMark score depends on the compiler version. 11.3 Peripheral power consumption The supply current per peripheral is measured as the difference in supply current between the peripheral block enabled and the peripheral block disabled in the SYSAHBCLKCFG and PDRUNCFG (for analog blocks) registers. All other blocks are disabled in both registers and no code accessing the peripheral is executed except for the ADC. Measured on a typical sample at Tamb = 25 C. Unless noted otherwise, the system oscillator and PLL are running in both measurements. The supply currents are shown for system clock frequencies of 12 MHz and 48 MHz. Table 9.

[2] Parameters are valid over operating temperature range unless otherwise specified. [3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge. [4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL. [5] Cb = total capacitance of one bus line in pF. [6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at 250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines without exceeding the maximum specified tf. [7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should allow for this when considering bus timing. [8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or tVD;ACK by a transition time (see UM10204). This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock. [9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the acknowledge. [10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time. LPC11U6x Product data sheet All information provided in this document is subject to legal disclaimers.

Application information 14.1 ADC usage notes The following guidelines show how to increase the performance of the ADC in a noisy environment beyond the ADC specifications listed in Table 22: * The ADC input trace must be short and as close as possible to the LPC11U6x chip. * The ADC input traces must be shielded from fast switching digital signals and noisy power supply lines. * If the ADC and the digital core share a power supply, the power supply line must be adequately filtered. * To improve the ADC performance in a very noisy environment, put the device in Sleep mode during the ADC conversion. 14.2 Typical wake-up times Table 25. Typical wake-up times VDD = 3.3 V; Tamb = 25 C Power modes Wake-up time Sleep mode (12 MHz)[1][2] 2.6 s Deep-sleep mode[1][3] 4.4 s Power-down 86.8 s mode[1][3] Deep Power-down mode[4] 276 s [1] The wake-up time measured is the time between when a GPIO input pin is triggered to wake up the device from the low-power modes and from when a GPIO output pin is set in the interrupt service routine (ISR) wake-up handler. [2] IRC enabled, all peripherals off. [3] WatchDog oscillator disabled, Brown-Out Detect (BOD) disabled. [4] Wake-up from deep power-down causes the part to go through entire reset process. The wake-up time measured is the time between when a wake-up pin is triggered to wake up the device from the low-power modes and when a GPIO output pin is set in the reset handler. 14.3 Suggested USB interface solutions The USB device can be connected to the USB as self-powered device (see Figure 38) or bus-powered device (see Figure 39). On the LPC11U6x, the PIO0_3/USB_VBUS pin is 5 V tolerant only when VDD is applied and at operating voltage level. Therefore, if the USB_VBUS function is connected to the USB connector and the device is self-powered, the USB_VBUS pin must be protected for situations when VDD = 0 V. If VDD is always at operating level while VBUS = 5 V, the USB_VBUS pin can be connected directly to the VBUS pin on the USB connector. For systems where VDD can be 0 V and VBUS is directly applied to the VBUS pin, precautions must be taken to reduce the voltage to below 3.6 V, which is the maximum allowable voltage on the USB_VBUS pin in this case.

All rights reserved. 75 of 97 LPC11U6x NXP Semiconductors 32-bit ARM Cortex-M0+ microcontroller One method is to use a voltage divider to connect the USB_VBUS pin to the VBUS on the USB connector. The voltage divider ratio should be such that the USB_VBUS pin is greater than 0.7 VDD to indicate a logic HIGH while below the 3.6 V allowable maximum voltage. For the following operating conditions VBUSmax = 5.25 V VDD = 3.6 V, the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V.

USB interface on a self-powered device where USB_VBUS = 5 V The USB_CONNECT function can be enabled internally by setting the DCON bit in the DEVCMDSTAT register to prevent the USB from timing out when there is a significant delay between power-up and handling USB traffic. External circuitry is not required for the USB_CONNECT functionality. LPC11U6x Product data sheet All information provided in this document is subject to legal disclaimers.

In this case, the USB_VBUS signal is HIGH whenever the part is powered. (2) Connect the VBUS signal directly from the connector to the USB_VBUS pin. In this case, 5 V are applied to the USB_VBUS pin while the regulator is ramping up to supply VDD. Since the PIO0_3/USB_VBUS pin is only 5 V tolerant when VDD is at operating level, this connection can degrade the performance of the part over its lifetime. Simulation shows that lifetime is reduced to 15 years at Tamb = 45 C and 8 years at Tamb = 55 C assuming that USB_VBUS = 5 V is applied continuously while VDD = 0 V. Fig 39. USB interface on a bus-powered device Remark: When a self-powered circuit is used without connecting VBUS, configure the PIO0_3/USB_VBUS pin for GPIO (PIO0_3) and provide software that can detect the host presence through some other mechanism before enabling USB_CONNECT and the SoftConnect feature. Enabling the SoftConnect without host presence leads to USB compliance failure. 14.3.1 USB Low-speed operation The USB device controller can be used in low-speed mode supporting 1.5 Mbit/s data exchange with a USB host controller. Remark: To operate in low-speed mode, change the board connections as follows: 1. Connect USB_DP to the D- pin of the connector. 2. Connect USB_DM to the D+ pin of the connector. Use the IRC as clock source for the USB PLL to generate 48 MHz, then set the USB clock divider USBCLKDIV to 8 for a 6 MHz USB clock (see Figure 10 "Clock generation"). External 10 resistors are recommended in low-speed mode to reduce over-shoots and accommodate for 5 m cable length required for USB-IF testing.

USB interface for low-speed, XTAL-less operation 14.4 XTAL input and crystal oscillator component selection The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV(RMS) is needed. LPC1xxx XTALIN Ci 100 pF Cg 002aae788 Fig 41. Slave mode operation of the on-chip oscillator In slave mode the input clock signal should be coupled through a capacitor of 100 pF (Figure 41), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected.

Take care that the load capacitors Cx1, Cx2, and Cx3 in case of third overtone crystal usage have a common ground plane. The external components must also be connected to the ground plane. Loops must be made as small as possible to keep the noise coupled in via the PCB as small as possible. Also parasitics should stay as small as possible. Smaller values of Cx1 and Cx2 should be chosen according to the increase in parasitics of the PCB layout.

In many cases, unused pins may should be connected externally or configured correctly by software to minimize the overall power consumption of the part. Unused pins with GPIO function should be configured as outputs set to LOW with their internal pull-up disabled. To configure a GPIO pin as output and drive it LOW, select the GPIO function in the IOCON register, select output in the GPIO DIR register, and write a 0 to the GPIO PORT register for that pin. Disable the pull-up in the pin's IOCON register. In addition, it is recommended to configure all GPIO pins that are not bonded out on smaller packages as outputs driven LOW with their internal pull-up disabled. Table 28. Termination of unused pins Pin Default state[1] Recommended termination of unused pins RESET/PIO0_0 I; PU In an application that does not use the RESET pin or its GPIO function, the termination of this pin depends on whether Deep power-down mode is used: * Deep power-down used: Connect an external pull-up resistor and keep pin in default state (input, pull-up enabled) during all other power modes. * Deep power-down not used and no external pull-up connected: can be left unconnected if internal pull-up is disabled and pin is driven LOW and configured as output by software. all PIOn_m (not open-drain) I; PU Can be left unconnected if driven LOW and configured as GPIO output with pull-up disabled by software.
