Internal DC-DCs 5.21.2 Power-Up and Shut-Down States The correct power-up and shut-down sequences must be followed to avoid damage to the device. While VBAT or VIO or both are deasserted, no signals should be driven to the device. The only exception is the slow clock that is a fail-safe I/O. While VBAT, VIO, and slow clock are fed to the device, but WL_EN is deasserted (low), the device is in SHUTDOWN state. In SHUTDOWN state all functional blocks, internal DC-DCs, clocks, and LDOs are disabled. To perform the correct power-up sequence, assert (high) WL_EN. The internal DC-DCs, LDOs, and clock start to ramp and stabilize. Stable slow clock, VIO, and VBAT are prerequisites to the assertion of one of the enable signals. To perform the correct shut-down sequence, deassert (low) WL_EN while all the supplies to the device (VBAT, VIO, and slow clock) are still stable and available. The supplies to the chip (VBAT and VIO) can be deasserted only after both enable signals are deasserted (low). Figure 5-2 shows the general power scheme for the module, including the power-down sequence. 20 Specifications Copyright (c) 2014-2017, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: WL1807MOD WL1837MOD WL1807MOD, WL1837MOD www.ti.com SWRS170I - AUGUST 2014 - REVISED OCTOBER 2017 VBAT 1 VIO 5 5 EXT_32K >10 s 2 >10 s 4 3 WLEN > 60 s NOTE: NOTE: NOTE: NOTE: NOTE: NOTE: NOTE: NOTE: 1.

The device is assumed to be in shutdown state during that period, meaning all enables to the device are LOW for that minimum duration. 4.

After power up, the baud rate is set for 115.2 Kbps, regardless of the fast-clock frequency. The baud rate can then be changed using a VS command. The device responds with a Command Complete Event (still at 115.2 Kbps), after which the baud rate change occurs. HCI hardware includes the following features: * Receiver detection of break, idle, framing, FIFO overflow, and parity error conditions * Receiver-transmitter underflow detection * CTS, RTS hardware flow control * 4 wire (H4) Table 5-4 lists the UART default settings. Table 5-4. UART Default Setting PARAMETER Bit rate VALUE 115.2 Kbps Data length Stop-bit 8 bits 1 Parity None 5.21.7.1 UART 4-Wire Interface - H4 The interface includes four signals: * TXD * RXD * CTS * RTS Flow control between the host and the device is byte-wise by hardware. When the UART RX buffer of the device passes the flow-control threshold, the buffer sets the UART_RTS signal high to stop transmission from the host. When the UART_CTS signal is set high, the device stops transmitting on the interface. If HCI_CTS is set high in the middle of transmitting a byte, the device finishes transmitting the byte and stops the transmission.

For more information, see the Pulse Electronics W3006 product page. 7.1.2 Design Recommendations This section describes the layout recommendations for the WL1837 module, RF trace, and antenna. Table 7-2 summarizes the layout recommendations. Table 7-2. Layout Recommendations Summary ITEM DESCRIPTION Thermal 1 The proximity of ground vias must be close to the pad. 2 Signal traces must not be run underneath the module on the layer where the module is mounted. 3 Have a complete ground pour in layer 2 for thermal dissipation. 4 Have a solid ground plane and ground vias under the module for stable system and thermal dissipation. 5 Increase the ground pour in the first layer and have all of the traces from the first layer on the inner layers, if possible. 6 Signal traces can be run on a third layer under the solid ground layer, which is below the module mounting layer. RF Trace and Antenna Routing 36 7 The RF trace antenna feed must be as short as possible beyond the ground reference. At this point, the trace starts to radiate. 8 The RF trace bends must be gradual with an approximate maximum bend of 45 with trace mitered. RF traces must not have sharp corners. 9 RF traces must have via stitching on the ground plane beside the RF trace on both sides. 10 RF traces must have constant impedance (microstrip transmission line). 11 For best results, the RF trace ground layer must be the ground layer immediately below the RF trace. The ground layer must be solid. 12 There must be no traces or ground under the antenna section. 13 RF traces must be as short as possible. The antenna, RF traces, and modules must be on the edge of the PCB product. The proximity of the antenna to the enclosure and the enclosure material must also be considered.

Layout Recommendations Summary (continued) ITEM DESCRIPTION Supply and Interface 14 The power trace for VBAT must be at least 40-mil wide. 15 The 1.8-V trace must be at least 18-mil wide. 16 Make VBAT traces as wide as possible to ensure reduced inductance and trace resistance. 17 If possible, shield VBAT traces with ground above, below, and beside the traces. 18 SDIO signals traces (CLK, CMD, D0, D1, D2, and D3) must be routed in parallel to each other and as short as possible (less than 12 cm). In addition, every trace length must be the same as the others. There should be enough space between traces - greater than 1.5 times the trace width or ground - to ensure signal quality, especially for the SDIO_CLK trace. Remember to keep these traces away from the other digital or analog signal traces. TI recommends adding ground shielding around these buses. 19 SDIO and digital clock signals are a source of noise. Keep the traces of these signals as short as possible. If possible, maintain a clearance around them. 7.1.3 RF Trace and Antenna Layout Recommendations Figure 7-2 shows the location of the antenna on the WL1837MODCOM8I board as well as the RF trace routing from the WL1837 module (TI reference design). The Pulse multilayer antennas are mounted on the board with a specific layout and matching circuit for the radiation test conducted in FCC, CE, and IC certifications. Antennas are orthogonal to each other. Antennas distance is Higher than half wavelength. 76.00 mm No sharp corners. Constant 50 control impedance RF Trace. Antenna placement on the edge of the board. Figure 7-2. Location of Antenna and RF Trace Routing on the WL1837MODCOM8I Board Follow these RF trace routing recommendations: * RF traces must have 50- impedance. * RF traces must not have sharp corners. * RF traces must have via stitching on the ground plane beside the RF trace on both sides. * RF traces must be as short as possible. The antenna, RF traces, and module must be on the edge of the PCB product in consideration of the product enclosure material and proximity.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers' own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer's noncompliance with the terms and provisions of this Notice.
