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

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

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
