S5PC100 USER'S MANUAL (REV1.0)
2.2
1 OVERVIEW
S5PC100 includes 203 multi-functional input/ output pins and 108 memory pins. There are 29 general groups and
2 memory groups as listed below:
• GPA0: 8 in/out pin – 2xUART with flow control
• GPA1: 5 in/out pin – 2xUART without flow control or 1xUART with flow control, 1x IrDA
• GPB: 8 in/out pin – 2x SPI
• GPC: 5 in/out pin – I2S, PCM, AC97
• GPD: 7 in/out pin – 2xI2C, PWM, External DMA request, SPDIF
• GPE0,1: 14 in/out pin – Camera I/F 0, MMC channel1(GPE0 supports 4-bit mode MMC, if 8-bit mode is
needed, use GPE1 for another 4-bit data channel)
• GPF0,1,2,3: 28 in/out pin – LCD I/F
• GPG0,1,2,3: 25 in/out pin – 3xMMC channel (Channel 0 supports 4-bit and 8-bit mode, but channel 1, channel
2 supports only 4-bit mode), SPI, I2S, PCM, SPDIF
• GPH0,1,2,3: 32 in/out pin – CAM IF channel, Key pad, External Wake-up (up-to 32-bit)
• GPI: 8 in/out pin – Booting option, PWI
• GPJ0,1,2,3,4: 33 in/out pin – Modem IF, HSI, ATA
• GPK0,1,2,3: 30 in/out pin – Control signals of EBI(SMC, NF, CF, OneNAND)
• GPL: 37 in/out memory pin – EBI(refer chapter 5,6 for detail description of EBI configuration) & GPIO
• MP1: 71 DRAM pin
• ETC0,1,2,3 : XjTRSTn, XjTMS, XjTDI, XI2S0, XusbXTI/XusbXTO, XrtcXTI/XrtcXTO ...
