 详细说明:这个文档是GPCV1248A主芯片的介绍文档,对硬件工程师或许很有用,但是对于我一个嵌入式软件工程师作用并不大,因为里面没有寄存器地址操作介绍,也没有地址说明. 而且我在网上找到它的资料微乎其微,但里面的大概功能和GPIO引脚说明还是有的,有一定的参考价值,至少进一步了解这款主芯片.Preliminary Generalplus GPCV1248A VEHICLE CAMERA RECORDER SOC SOLUTION GENERAL DESCRIPTION standard supported The GPCV1248A, a highly integrated Soc(System-On-a-Chip) MIPI RX with one data lane supported for vehicle camera recorder, is based on a high performance and ■TFT- LCD controller power efficient ARM7TDMI core operating at up to 144 MHz and is UPS051(serial RGB) enhanced with image, video processing, power saving, and UPS052(serial RGB dummy) system peripherals ParalleI-RGB with 18/16/8-bit data(6-6-6,5-6-5,8) 180(8-bit system bus)I/F type The high-speed MJPEg engine is capable of supporting up to ●cC|R601ccR656. 720P 30fps video compression. Other main features include a a Universal Serial Bus (USB)2.0 high/full speed compliance high-performance Image Signal ocessing (ISP hardware-accelerating pipeline to boost the conventional atchdog timer raw-data CMOs sensor up to 3M pixels and an HDM TX for SD/ SDHC/ SDIO/ MMC card interfaces HDTV output to deliver high-resolution graphics. The SPI(master/slave)interface with data rate up to 24Mbp GPCV1248A processor is designed to connect with various types TwO UART (asynchronous serial l/O)interfaces with baud rate of memory card interfaces such as SD, SDHC, SDIO, and MMC up to 1.8432Mbps and 1152Kbps. The UART interface can be configured as smart card interface(ISo7816 These fully featured peripherals and functions make GPCV1248A ■12 C controller one of the best vehicle camera Soc solutions in the industry a Built-in power control macro which provide two power control making your products more competitive in today's market pin for power on/off control and 2 PWM output for driving LED 3.6V(BAT IN)to 3.3V LDo for 1/O 3.3V to 1.2V LDo for core logic 2 FEATURES I 3.6V(BAT IN)to 2.8V LDO for CMOs sensor ARMTTDMI CPU with 8KB unified ID-cache embedded jtag a Dedicated 3.6V(BAT IN)to 3.3V LDO for ADC/DAC ICE, and working frequency up to 144MHZ Independent power Real-time clock(RTC) JPEG CODEC supports MJPEG 1280x720 30fps Internal 12MHz generator(XCKGEN) with 32768Hz Crystal input encode/decode function ISP for CMOS sensor raw data processing 16-bit stereo DAC(2-channel) for audio playback 12-bit ADc with four line-in channels and two internal SPI Flash controller which supports 1-bit/2-bit/4-bit I0 mode channels for battery and 1.2V measurement The max. freg of sPl clock is 70MHz HDMI V1.2 supports both 480p and 720p 16-bit Sigma-Delta ADC with MIC and PGA ■LQFP128 TVencoder with 10-bit VDAC Video-in Cmos sensor interface and CCIR601/CCIR656 O Generalplus Technology Inc Aug28,2014 Proprietary Confidential Preliminary Version: 0.1 Preliminary Generalplus GPCV1248A 3 BLOCK DIAGRAM ARM sub syst ARM TDMI With& ld cache CSI MIPI TFT HDMI TV JPEGIL SDRAM Controller AHB SPI Flas USB20 ISP DMA Controller Device AHB2 APB bridge LDO Audio SAR GPIOI RTC Time 3.3V/2.8V/1.2V DAC ADC PLLS B ase AP LDO CODEC/ SD Power Sigma Delta Controller ADC with MIC SPI I2C UARTO UARTI O Generalplus Technology Inc Aug28,2014 Proprietary Confidential Preliminary version: 0 Preliminary Generalplus GPCV1248A 4 SIGNAL DESCRIPTION PKG No Name Group T Normal Function Description X32Ko RTC Ao Xtal 32768Hz output PLL V33 PLL 3.3V PLL Power 12M PLL A Xtal 1 2MHZ input 3456 V12 CORE PWR 1.2V Core Power Digital GND Digital ground IOD15 SD SD DATA2 IOD12 SD SD DATA3 IOD10 SD CMD 9 IOD11 SD SD CLK 10 IOD13 SD DATAO lOD14 SD SD DATA1 12 GPIO lOAB lOAn 12C SCI 14 IOA10 12C I2C SDA IO PWR Po IOA11 TET TET CS JOA12 GPIO lOAf 18 IOA13 GPIO IOA13 Digital GND P Digital ground JOA14 GPIO JOA14 21 JOA15 GPIO lOA15 lOB GPIO JOB5 1OB4 TET TET TE 24 lOB TET CLK lOB TET TET VSYNC JOB1 TFT TET HSYNC 27 lOB TET TFTD IOC12 JTAG TDI IOC13 ICE JTAG TDO 30 V12 CORE PWR 1.2V Core pot 31 IOC14 ICE JTAG TCK 32 V33 IO PWR 3.3V IO Power IOC15 ICE JTAG TMS 34 Digital GND 36 lOBe GPIO JOB9 GPIO lOB10 38 JOB11 GPIO JOB11 JOB12 GPIO JOB12 40 IOB13 GPIO IOB13 JOB14 GPIO lOB14 lOB15 GPIO JOB15 USB VDA V33 USB 3.3V USB Power 44 DM USB AlO SB DM O Generalplus Technology Inc Aug28,2014 Proprietary Confidential Preliminary version: 0 Preliminary Generalplus GPCV1248A PKG No Name Group T Normal Function Description 45 DP USB AlO USB DP USB VDA VSS SB Ground 47 AOUT VDAC AO VDAC AOUT CBU VDAC VDAC CBU 49 HDMI V33 HDMI 3.3V HDMI Power 1.2V HDMI Power 51 HDMI VSS HDMI P HDMI ground HDMI VSS HDM 53 IOE HDMI HDMI TXP2 IOE HDMI HDMI TXN2 IOE HDMI HDMI TXP1 56 IOE HDMI HDMI TXN 1 IOE3 HDMI HDMI TXPO 58 IOE2 HDMI HDMI TXNO IOE HDMI HDMI TXCP 60 lEO HDMI HDMI TXCN NC NC JOC 11 CSI VSYNC 64 IOC10 CSI HSYNC CSI CLKO IOC CSI CLKI V12 CORE PWR P 1.2V Core Power Digital GND P Digital OC7 CSI CSI D9 70 lOCO CSI D8 71 CSI D7 Digital GND Digital ground 73 OC4 74 lOC3 CSI D5 75 V33 IO PWR 3.3V IO Power IOC 1 CSI CSI D3 lOCO CSI D2 79 Digital GND Digital ground lOBe CSI DO 81 0B7 CSI D1 SPI CS 83 IOD7 SPI SPI CLK IO PWR 3.3V IO Powel 85 IOD8 SPI SPI TX lOD9 SPI RX 87 lODO SPIF SPI Flash CSB V12 CORE PWR 1.2∨ Core Power 89 lOD1 SPIF SPI Flash CLK O Generalplus Technology Inc 6 Aug28,2014 Proprietary Confidential Preliminary Version: 0.1 Preliminary Generalplus GPCV1248A PKG No Name Group T Normal function Description 90 lOD2 SPIF SPI Flash RXO IOD3 SPIF SPI Flash RX 1 92 lOD4 SPIF SPI Flash RX2 SPIF SPI Flash RX3 JOAO TET TETDO JOA1 TFT TET D 0A2 TET TET D2 0A3 TET TET D3 FT TET D4 IOA5 TET TET D5 100 lOAd TET TET D6 101 TET TET DZ 102 RESETB SYSTEM External RESETB(Low active) 103 TEST SYSTEM Test enable(High active) 104 DACOL AuDA Audio dAc left channel output 105 DACOR AUDA Audio dac right channel output DACVREF AUDA Audio daccodEc Adc vref 107 V33 DA16 AUDAC 3.3V Power for audAc/coDEC ADcSaR adc VSS DA16 AUDA Ground for auda/codEC ADc/sar adc 109 LINEIN1 SARADC SAR ADC LINEIN1 110 LINEINO SARADC SAR ADC LINEINO 111 MICIN CODEC ADC CODEC ADC microphone input MICBIAS CODEC ADC phone bias outp CODEC ADC microphone bi 113 LINEIN CODEC ADC A CODEC ADC left channel in LINEINR CODEC ADC ODEC ADc right channel input 115 BAT IN SYSTEM Battery input Power mode selection 0: enable 116 PWR SEL SYSTEM internal LDO33 1: disable internal LDO3 PWMO output; PWMo can work even 3.3V and 1.2V 117 WMO STEM Ao is of.
