Power Management Handshake Interface Signal Level 1) SD_RESET Signal Level The SD_RESET signal level ranges from 1.8V to 3.3V. The host provides the power source with the targeted power level to the GOC-RG440-WZ via the VDD_IO pin. 2) BT_DIS Signal Level The BT_DIS signal level ranges from 1.8V to 3.3V. The host provides the power source with the targeted power level to the GOC-RG440-WZ via the VDD_IO_1 pin. 3) WL_DIS_N Signal Level The WL_DIS_N signal level ranges from 1.8V to 3.3V. The host provides the power source with the targeted power level to the RTL8821CS via the VDD_IO pin. 4) VBAT_EN Signal Level The VBAT_EN signal level ranges from 1.8V to 3.3V 9 8.1 System Power On Sequence GOC-RG440 Module Hardware Specification Figure 6: System Power-On Sequence T18_Ramp T33_Ramp TChip_Ready Min Typical Max Unit Description 0.1 0.1 0 2.5 ms The 1.8V main power ramp up duration. 2.5 ms The 3.3V main power ramp up duration. X ms CHIP_EN pull high timing 0.5 0.5 10 TSDIO_Ready 1 2 10 ms SDIO Not Ready Duration. In this state, the RTL8821CS may respond to commands without the ready bit being set. After the ready bit is set, the host will initiate complete card detection procedure. NOTE:
1) SDIO Interface Power On Sequence Table 3: System Power On Timing Parameters After power-on, the SDIO interface is selected by the RTL8821CS automatically when a valid SDIO command is received. To attain better SDIO host compatibility, the following power-on sequence is recommended. We recommend that the card detection procedures are divided into two phases: A 3.3V/1.8V power pre-charge phase and a formal power-up phase. After main 3.3V ramp up and 1.8V ramp up, the power management unit is enabled by the power ready detection circuit. The power management unit enables the SDIO block. eFUSE is then autoloaded to SDIO circuits during the TSDIO_Ready duration and then SDIO pins are pulled up. After CMD5/5/3/7 procedures,card detection is executed. 2) SD_RESET Power On Sequence To attain SD_RESET capability, the following power sequence is recommended. After main 3.3V/1.8V ramp up, the power management unit is enabled by the power ready 10 GOC-RG440 Module Hardware Specification detection circuit. The power management unit enables the SD_RESET function. After power management unit being enabled, SD_RESET needs to keep high for ensuring WLAN and SDIO/G-SPI function being alive. 3) CHIP_EN Power On Sequence To attain CHIP_EN capability, the following power sequence is recommended. After main 3.3V/1.8V ramp up, the power management unit is enabled by the power ready detection circuit. The power management unit enables the CHIP_EN function. After power management unit being enabled, CHIP_EN needs to keep high for ensuring RTL8821CS function being alive. 7.
