description

The TMS320LF240xA and TMS320LC240xA devices, new members of the TMS320C24x generation of

digital signal processor (DSP) controllers, are part of the TMS320C2000 platform of fixed-point DSPs. The

240xA devices offer the enhanced TMS320DSP architectural design of the C2xx core CPU for low-cost,

low-power, and high-performance processing capabilities. Several advanced peripherals, optimized for digital

motor and motion control applications, have been integrated to provide a true single-chip DSP controller. While

code-compatible with the existing C24x DSP controller devices, the 240xA offers increased processing

performance (40 MIPS) and a higher level of peripheral integration. See the TMS320x240xA Device Summary

section for device-specific features.

The 240xA generation offers an array of memory sizes and different peripherals tailored to meet the specific

price/performance points required by various applications. Flash devices of up to 32K words offer a

cost-effective reprogrammable solution for volume production. The 240xA devices offer a password-based

“code security” feature which is useful in preventing unauthorized duplication of proprietary code stored in

on-chip Flash/ROM. Note that Flash-based devices contain a 256-word boot ROM to facilitate in-circuit

programming. The 240xA family also includes ROM devices that are fully pin-to-pin compatible with their Flash

counterparts.

All 240xA devices offer at least one event manager module which has been optimized for digital motor control

and power conversion applications. Capabilities of this module include center- and/or edge-aligned PWM

generation, programmable deadband to prevent shoot-through faults, and synchronized analog-to-digital

conversion. Devices with dual event managers enable multiple motor and/or converter control with a single

240xA DSP controller. Select EV pins have been provided with an “input-qualifier” circuitry, which minimizes

inadvertent pin-triggering by glitches.

The high-performance, 10-bit analog-to-digital converter (ADC) has a minimum conversion time of 375 ns and

offers up to 16 channels of analog input. The autosequencing capability of the ADC allows a maximum of

16 conversions to take place in a single conversion session without any CPU overhead.

A serial communications interface (SCI) is integrated on all devices to provide asynchronous communication

to other devices in the system. For systems requiring additional communication interfaces, the 2407A, 2406A,

2404A, and 2403A offer a 16-bit synchronous serial peripheral interface (SPI). The 2407A, 2406A, and 2403A

offer a controller area network (CAN) communications module that meets 2.0B specifications. To maximize

device flexibility, functional pins are also configurable as general-purpose inputs/outputs (GPIOs).

To streamline development time, JTAG-compliant scan-based emulation has been integrated into all devices.

This provides non-intrusive real-time capabilities required to debug digital control systems. A complete suite

of code-generation tools from C compilers to the industry-standard Code Composer Studio debugger

supports this family. Numerous third-party developers not only offer device-level development tools, but also

system-level design and development support.

EXTERNAL INTERRUPTS, CLOCK

RS 133 93 93 28

Device Reset (in) and Watchdog Reset (out).

Device reset. RS causes the device to terminate execution

and to set PC = 0. When RS is brought to a high level,

execution begins at location 0x0000 of program memory.

This pin is driven low by the DSP when a watchdog reset

occurs. During watchdog reset, the RS pin will be driven

low for the watchdog reset duration of 128 CLKIN cycles.

The output buffer of this pin is an open-drain with an

internal pullup (20 µA, typical). It is recommended that this

pin be driven by an open-drain device. (↑)

PDPINTA 7 6 6 36

Power drive protection interrupt input. This interrupt, when

activated, puts the PWM output pins (EVA) in the

high-impedance state should motor drive/power converter

abnormalities, such as overvoltage or overcurrent, etc.,

arise. PDPINTA is a falling-edge-sensitive interrupt. (↑)

DESCRIPTION

OSCILLATOR, PLL, FLASH, BOOT, AND MISCELLANEOUS (CONTINUED)

PLLF2 10 8 8 37 PLL loop filter input 2

VCCP (5V) 58 40 40 60

Flash programming voltage pin. This pin must be connected to

a 5-V supply for Flash programming. The Flash cannot be

programmed if this pin is connected to GND. When not

programming the Flash (i.e., during normal device operation),

this pin can either be left connected to the 5-V supply or it can

be tied to GND. This pin must not be left floating at any time. Do

not use any current-limiting resistor in series with the 5-V supply

on this pin. This pin is a “no connect” (NC) on ROM parts (i.e.,

this pin is not connected to any circuitry internal to the device).

Connecting this pin to 5 V or leaving it open makes no difference

on ROM parts.

TP1 60 42 42 61 Test pin 1. Do not connect.

TP2 63 44 44 62 Test pin 2. Do not connect.

BIO/IOPC1 119 85 85

Branch control input. BIO is polled by the BCND pma,BIO

instruction. If BIO is low, a branch is executed. If BIO is not used,

it should be pulled high. This pin is configured as a branch

control input by all device resets. It can be used as a GPIO, if

not used as a branch control input. (↑)

EMULATION AND TEST

EMU0 90 61 61 7

Emulator I/O #0 with internal pullup. When TRST is driven high,

this pin is used as an interrupt to or from the emulator system

and is defined as input/output through the JTAG scan. (↑)

EMU1/OFF 91 62 62 8

Emulator pin 1. Emulator pin 1 disables all outputs. When TRST

is driven high, EMU1/OFF is used as an interrupt to or from the

emulator system and is defined as an input/output through the

JTAG scan. When TRST is driven low, this pin is configured as

OFF. EMU1/OFF, when active low, puts all output drivers in the

high-impedance state. Note that OFF is used exclusively for

testing and emulation purposes (not for multiprocessing

applications). Therefore, for the OFF condition, the following

apply:

TRST = 0

EMU0 = 1

EMU1/OFF = 0 (↑)

TCK 135 94 94 29 JTAG test clock with internal pullup (↑)

†Bold, italicized pin names indicate pin function after reset.

‡GPIO − General-purpose input/output pin. All GPIOs come up as input after reset.

DESCRIPTION

EMULATION AND TEST (CONTINUED)

TDI 139 96 96 30

JTAG test data input (TDI) with internal pullup. TDI

is clocked into the selected register (instruction or

data) on a rising edge of TCK. (↑)

TDO 142 99 99 31

JTAG scan out, test data output (TDO). The

contents of the selected register (instruction or

data) is shifted out of TDO on the falling edge of

TCK. (↓)

TMS 144 100 100 32

JTAG test-mode select (TMS) with internal pullup.

This serial control input is clocked into the TAP

controller on the rising edge of TCK. (↑)

TMS2 36 25 25 48

JTAG test-mode select 2 (TMS2) with internal

pullup. This serial control input is clocked into the

TAP controller on the rising edge of TCK. Used for

test and emulation only. This pin can be left

unconnected in user applications. If the PLL bypass

mode is desired, TMS2, TMS, and TRST should be

held low during reset. (↑)

TRST 1 1 1 33

JTAG test reset with internal pulldown. TRST, when

driven high, gives the scan system control of the

operations of the device. If this signal is not

connected or driven low, the device operates in its

functional mode, and the test reset signals are

ignored. (↓)

NOTE: Do not use pullup resistors on TRST; it has

an internal pulldown device. TRST is an active high

test pin and must be maintained low at all times

during normal device operation. In a low-noise

environment, TRST may be left floating. In other

instances, an external pulldown resistor is highly

recommended. The value of this resistor should be

based on drive strength of the debugger pods

applicable to the design. A 2.2-kΩ resistor generally

offers adequate protection. Since this is

application−specific, it is recommended that each

target board be validated for proper operation of the

debugger and the application. (I ↓)

†Bold, italicized pin names indicate pin function after reset.

‡GPIO − General-purpose input/output pin. All GPIOs come up as input after reset.

DESCRIPTION

ADDRESS, DATA, AND MEMORY CONTROL SIGNALS (CONTINUED)

READY 120

READY is pulled low to add wait states for external accesses.

READY indicates that an external device is prepared for a bus

transaction to be completed. If the device is not ready, it pulls the

READY pin low. The processor waits one cycle and checks

READY again. Note that the processor performs

READY-detection if at least one software wait state is

programmed. To meet the external READY timing parameters,

the wait-state generator control register (WSGR) should be

programmed for at least one wait state. (↑)

MP/MC 118

Microprocessor/Microcomputer mode select. If this pin is low

during reset, the device is put in microcomputer mode and

program execution begins at 0000h of internal program memory

(Flash EEPROM). A high value during reset puts the device in

microprocessor mode and program execution begins at 0000h

of external program memory. This line sets the MP/MC bit (bit 2

in the SCSR2 register). (↓)

ENA_144 122

Active high to enable external interface signals. If pulled low, the

2407A behaves like the 2406A/2403A/2402A—i.e., it has no

external memory and generates an illegal address if DS is

asserted. This pin has an internal pulldown. (↓)

VIS_OE 97

Visibility output enable (active when data bus is output). This pin

is active (low) whenever the external data bus is driving as an

output during visibility mode. Can be used by external decode

logic to prevent data bus contention while running in visibility

mode.
