Components
- SoC: Samsung S3C6410 (datasheet)
- internal storage: SanDisk iNAND
- RAM: 2x Qimonda HYB25DC512160CF-6 (datasheet)
- Crytomemory/EEPROM: Atmel AT88SC (datasheet)
- Wi-fi: Universal Scientific Industrial WM-G-MR-09 (datasheet, based on Marvell 88W8686)
- Audio codec: Wolfson WM8987G (datasheet)
- Backlight: Monolithic Power Systems MP1530DM (datasheet)
- Speaker amplifier: Fangtek ft690M (datasheet)
- LCD panel: AUO A070VW04 (datasheet)
Connections
The S3C6410 SoC has 3 SD ports, one has the iNand connected and the external SD port, the other has the SDIO wi-fi chip connected. (unsure whether using these 3 at the *same* time is possible due to GPIO sharing)
The audio codec is connected through I²C (control, address 0x?) and I²S (audio transport).
GPIO ports
- AT88SC: N0 -> SCL, N1 -> SDA (emulated I²C bus)
- LCD panel: M0 -> LCD enable, M1 -> SCL, M2 -> SDA (emulated I²C bus)
- backlight: F15 (== PWM_TOUT1)
- Speaker: K12 -> en-/disable
- Headphone: L12 -> insertion detection
- Video amplifier: K13 -> en-/disable
- Wi-fi: K1 -> en/dis-able, K2 -> reset
- System power: K15 -> power control, L14 -> system power hold over 5 second time, pull up K15 (?)
- Charger: L13 -> DC insertion detection, K4 -> charging status 1, K5 -> charging status 2, K6 -> 0: 200ma 1: 860ma
- External SD card: K0 -> write protect detection
- USB: L0 -> USB voltage en-/disable, L1 -> USB host 5V en-/disable, L10 -> USB host over-current protection status, L11 -> USB OTG over-current protection status, L8 -> USB OTG enable
- LEDs: N9 -> green LED (?), N8 -> red LED (?) (note: set 1 to enable, set 0 to disable)
