General Description

The GP327902B, a highly integrated SoC (System-On a Chip), offers a great cost-effective and high performance ratio solution for Multimedia Processor applications. It is embedded the ARM7TDMI with 4K-byte unified ID-cache and many tremendous features such as JPEG CODEC engine, TFT-LCD interface, CMOS sensor interface, scalar engine, SDRAM controller, UART interface, 4-channel DMA controller, 6-channel 16-bit timers, RTC, SD/MMC card interface, USB 2.0 mini-host/device, interrupt controller, SPI (master/slave) controller, programmable I/O ports, stereo 16-bit DAC for audio playback, 2-channel 12-bit ADC, MIC, PLL, and 1K-byte embedded SRAM. With a complete set of common system peripherals, the GP327902B chip minimizes overall system cost and no additional component needs to be added. Not only does GP327902B feature the high-speed performance, but it is also a cost-effective system and the most importantly - compatible with all ARM based programs.
