= Motorola C123 = The C123 seems to be one of many ODM phones that Motorola bought from Compal communications in Taiwan. It seems (nearly?) identical with the C118. == Specifications == * GSM 900 / GSM 1800 dual-band * 101x45x21 mm, 86 grams * no GPRS * 920mAh Li-Ion battery * Ti Calypso/Iota/Rita chipset == Hardware == === GSM Chipset === * DBB: Ti Calypso Baseband, D751749ZHH model * ABB: Ti TWL3025BZGR * RF: TRF6151C * RF PA: SKY77324-12 === NOR Flash === * Intel 28F160C3TD (16Mbits, i.e. 2 MByte) Advanced+ Boot Block Flash Memory (C3) * Data sheet will be in git === SRAM === * ESMT M24L2161128SA-70BE (128k x16, i.e. 256kByte) * Data sheet [http://www.esmt.com.tw/DB/manager/upload/M24L216128SA.pdf available from vendor] === Display === The display is a 96x64 pixels monochrome LCD, attached via I2C bus to the Calypso DBB chip. The LCD controller inside the display is a [http://www.sitronix.com.tw/sitronix/product.nsf/Doc/ST7558?OpenDocument Sitronix ST7558], for which the data sheet is available. There is a community-based [https://calypso.gnumonks.org/trac/browser/phone/motorola_compal/C115/example_project driver implemented in PIC16 assembly] (in our git repository. We need a proper C language driver for it (any volunteers?) === Test Points === ==== Test points surrounding Iota ==== * TP4 -- BS_TDO, the JTAG TDO signal of the Iota (connected to TDI of Calypso) * TP5 -- Iota:TESTV pin * TP7 -- Uita:CK13M, connected from Calypso:CLK13M_OUT * TP29 -- Iota:ADIN1 (VADCID) * TP111 -- Iota:UDR (USP Rx), connects to Calypso:MCUDO * TP110 -- Iota:UEN (USP Enable), connects to Calypso:MCUEN0 * TP112 -- Iota:ONNOFF * TP114 -- Intoa:ITWAKEUP, connects to Calypso:RTC_ALARM * TP113 -- Iota:RESPWONZ, connects to Calypso:RTSPWRONZ * TP116 -- Iota:TEST3 * TP117 -- Iota:TEST4 ==== Test points surrounding Calypso ==== * TP11 -- Calypso:DSR_MODEM * TP12 -- Calypso:RTS_MODEM * TP23 -- Calypso:nCS4 * TP46 -- Calypso:CLK32K_OUT, connects to Iota:CK32K * TP118 -- Calypso:EXT_IRQ, connects to Iota:INT2 * TP115 -- Calypso:EXT_FIQ, connects to Iota:INT1 * TP45 -- Calypso:SCLK (I2C) * TP30 -- Calypso:nSCS1 (I2C) * TP44 -- Calypso:SDO (I2C) * TP34 -- Calyspo:nCS2 * TP48 -- Calypso:nCS3/INT4N * TP49 -- Calypso:VRDBB_1.5V * J2 -- Calypso NM_DAI_INTERFACE (MCSI_TXD, MCSI_CLK, MCSI_RXD, MCSI_RSYNCH, GND) ==== Test points accessible from battery compartment ==== * TP27 -- DLPWR (download power on), connects to Iota:RPWON * TP14 -- RxD Modem * TP13 -- TxD Modem * TP9 -- CTS Modem * TP39 -- GND
