Internal DC-DCs 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).

(HCI) transport layer. The HCI transports commands, events, and ACL between the Bluetooth device and its host using HCI data packets ack as a shared transport for all functional blocks except WLAN. Table 5-3 lists the transport mechanism for WLAN and bluetooth audio. Table 5-3. Transport Mechanism WLAN SHARED HCI FOR ALL FUNCTIONAL BLOCKS EXCEPT WLAN BLUETOOTH VOICE-AUDIO WLAN HS SDIO Over UART Bluetooth PCM The HCI UART supports most baud rates (including all PC rates) for all fast-clock frequencies up to a maximum of 4 Mbps. 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.

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.

Table 7-2 summarizes the layout recommendations. ITEM Thermal Table 7-2. Layout Recommendations Summary DESCRIPTION The proximity of ground vias must be close to the pad. Signal traces must not be run underneath the module on the layer where the module is mounted. Have a complete ground pour in layer 2 for thermal dissipation. Have a solid ground plane and ground vias under the module for stable system and thermal dissipation. Increase the ground pour in the first layer and have all of the traces from the first layer on the inner layers, if possible. 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 The RF trace antenna feed must be as short as possible beyond the ground reference. At this point, the trace starts to radiate. The RF trace bends must be gradual with an approximate maximum bend of 45 with trace mitered. 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 have constant impedance (microstrip transmission line). For best results, the RF trace ground layer must be the ground layer immediately below the RF trace. The ground layer must be solid. There must be no traces or ground under the antenna section. 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. 36 Applications, Implementation, and Layout Copyright 20142017, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: WL1807MOD WL1837MOD WL1807MOD, WL1837MOD SWRS170I AUGUST 2014 REVISED OCTOBER 2017 www.ti.com ITEM Supply and Interface 14 15 16 17 18 19 Table 7-2. Layout Recommendations Summary (continued) DESCRIPTION The power trace for VBAT must be at least 40-mil wide. The 1.8-V trace must be at least 18-mil wide. Make VBAT traces as wide as possible to ensure reduced inductance and trace resistance. If possible, shield VBAT traces with ground above, below, and beside the traces. 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. 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. 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.

Signal traces can be run on a third layer under the solid ground layer and beneath the module dissipation. mounting. Run the host interfaces with ground on the adjacent layer to improve the return path. TI recommends routing the signals as short as possible to the host. 7.1.5 Thermal Board Recommendations The TI module uses vias for layers 1 through 6 with full copper filling, providing heat flow all the way to the module ground pads. TI recommends using one big ground pad under the module with vias all the way to connect the pad to all ground layers (see Figure 7-5). Figure 7-5.

Follow MSL level 3 to perform the baking process. After the bag is open, devices subjected to reflow solder or other high temperature processes must be mounted within 168 hours of factory conditions (< 30C/60% RH) or stored at <10% RH. If the Humidity Indicator Card reads >10%, devices require baking before they are mounted. If baking is required, bake devices for 8 hours at 125C. 7.1.6.2 SMT Recommendations Figure 7-7 shows the recommended reflow profile for the WiLink 8 module. Figure 7-7. Reflow Profile for the WiLink 8 Module Table 7-3 lists the temperature values for the profile shown in Figure 7-7. Table 7-3.
