108 / 192 page  Signal Descriptions BCM4354 Data Sheet BROADCOM CONFIDENTIAL Broadcom® October 15, 2014 • 4354-DS109-R Page 107 Bluetooth/FM I2S 167 BT_I2S_CLK I/O I2S clock, can be master (output) or slave (input). 171 BT_I2S_DO I/O I2S data output 156 BT_I2S_DI I/O I2S data input 158 BT_I2S_WS I/O I2S WS; can be master (output) or slave (input). Bluetooth GPIOs 155 BT_GPIO_2 I/O Bluetooth general-purpose I/O 154 BT_GPIO_3 I/O Bluetooth general-purpose I/O 168 BT_GPIO_4 I/O Bluetooth general-purpose I/O 153 BT_GPIO_5 I/O Bluetooth general-purpose I/O Miscellaneous 319 WL_REG_ON I Used by PMU to power up or power down the internal BCM4354 regulators used by the WLAN section. Also, when deasserted, this pin holds the WLAN section in reset. This pin has an internal 200 kΩ pull- down resistor that is enabled by default. It can be disabled through programming. 320 BT_REG_ON I Used by PMU to power up or power down the internal BCM4354 regulators used by the Bluetooth/FM section. Also, when deasserted, this pin holds the Bluetooth/FM section in reset. This pin has an internal 200 kΩ pull-down resistor that is enabled by default. It can be disabled through programming. 176 BT_DEV_WAKE I/O Bluetooth DEV_WAKE 170 BT_HOST_WAKE I/O Bluetooth HOST_WAKE Integrated Voltage Regulators 340 SR_VDDBATA5V I Quiet VBAT 348 SR_VDDBATP5V I Power VBAT 336 SR_VLX O CBuck switching regulator output. Refer to Table 43 on page 158 for details of the inductor and capacitor required on this output. 342 LDO_VDD1P5 I LNLDO input 327 LDO_VDDBAT5V I LDO VBAT. 249 WRF_XTAL_VDD1P5 I XTAL LDO input (1.35V) 254 WRF_XTAL_VDD1P2 O XTAL LDO output (1.2V) 351 VOUT_LNLDO O Output of LNLDO 341 VOUT_CLDO O Output of core LDO 362 VOUT_BTLDO2P5 O Output of BT LDO 346 VOUT_LDO3P3_B O Output of 3.3V LDO 324 VOUT_3P3 O LDO 3.3V output Table 21: WLCSP Signal Descriptions (Cont.)
