Instructions to connect the SDIO interface to the SG909-0032
(SDIO 3.3V)
The SDIO interface follows the standard 3V SDIO Interface and is plug and play. There is no need to use
an external supply.
Instructions to connect the SDIO interface to the SG909-0033
(SDIO/SPI 1.8V)
The SDIO interface follows the standard SDIO slide card mechanical interface with the exception that the
SDIO VDD (SDIO PIN 4) is required to be 1.8V. The 1.8V voltage establishes the SDIO bus voltage rail
applied to the WLAN module and the low frequency clock oscillator.
Instructions to connect the SPI interface to the SG909-0033
(SDIO/SPI 1.8V)
1. Connect a +3.0 to 3.6V (min. 200mA) supply to JP1 pin 1. This is required to power the WLAN
2. Pins 7, 9, 10, 13, 15 and 16 of JP1 are ground returns for the external supply (all are tied together

2. Connect a 1.8V supply to JP1 pin 2. This voltage establishes the bus voltage rail applied to the
3. Connect the SPI Clock to JP1 pin 3
4. Connect the SPI Master out, Slave in (MOSI) to JP1 pin 4
5. Connect the SPI Master in, Slave out (MISO) to JP1 pin 5
6. Connect the SPI Chip Select to JP1 pin 6
7. Connect the power up control to JP1 pin 8. This pin is normally pulled to approximately 2V upon
8. Connect the SPI Interrupt Request (IRQ) to JP1 pin 11
9. Connect the 3.0 to 3.6V supply to JP1 pin 14. This pin selects the SPI mode of operation for all
