6 Detailed Description

The WiLink 8 module is a self-contained connectivity solution based on WiLink 8 connectivity. As the eighth-generation connectivity combo chip from TI, the WiLink 8 module is based on proven technology.

Table 6-1 through Table 6-3 list performance parameters along with shutdown and sleep currents.

Table 6-1 WLAN Performance Parameters

WLAN(3) SPECIFICATION (TYP) CONDITIONS
Maximum TX power 17.3 dBm 1 Mbps DSSS
Minimum sensitivity –96.3 dBm 1 Mbps DSSS
Sleep current 160 µA Leakage, firmware retained
Connected IDLE 750 µA No traffic IDLE connect
RX search 54 mA Search (SISO20)
RX current (SISO20) 65 mA MCS7, 2.4 GHz
TX current (SISO20)(1) 238 mA MCS7, 2.4 GHz, +11.2 dBm
Maximum peak current consumption during calibration(2) 850 mA
(1) WLAN maximum VBAT current draw of 725 mA with MIMO continues burst configuration.
(2) Peak current VBAT can hit 850 mA during device calibration.
  • At wakeup, the WiLink 8 module performs the entire calibration sequence at the center of the 2.4-GHz band.
  • Once a link is established, calibration is performed periodically (every 5 minutes) on the specific channel tuned.
  • The maximum VBAT value is based on peak calibration consumption with a 30% margin.
(3) System design power scheme must comply with both peak and average TX bursts.

6.5 Test Grades

To minimize delivery time, TI may ship the device ordered or an equivalent device currently available that contains at least the functions of the part ordered. From all aspects, this device will behave exactly the same as the part ordered. For example, if a customer orders device WL1801MOD, the part shipped can be marked with a test grade of 37, 07 (see Table 6-5).
