A1000的CPU就是一个16位的片
GPL162002A
16-BIT PLATFORM WITH μ’nSP 2.0
The Generalplus GPL162002A is highly integrated system-on-a chip and targets a cost-effective, high performance micro-controller solution for general-purpose applications. It embedded μ’nSP 2.0 (16-bit CPU developed by Generalplus Technology), 7-band EQ, 3D surround, UART/IrDA interface, four channel DMA controller, ROM/SRAM/NOR FLASH/NAND FLASH with ECC Memory controller, six-channel 16-bit timers, SD/MMC memory interface, USB mini-host/device, gray/color STN-LCD and TFT-LCD interface, interrupt controller, SPI master/slave controller, I2C master/slave controller, Key scan, Generalplus IO, programmable I/O ports, 16-bits DAC/ADC for audio playback/recode, stereo headphone amplifier, 10 bits ADC for touch panel, PLL, and embedded 30K*16 bits SRAM and 128K*16 ROM.
GPL162002A是一款高集成度的单芯片用于一般用途的经济型微控制器。其集成了u'nSP2.0内核，七段EQ，3D环绕，UART/IrDA（串口和红外）接口，4通道DMA控制器，ROM/SRAM/NOR FALSH/NAND FLASH ECC效验内存控制器，6通道16位计时器，SD/MMC存储器接口，USB 迷你主控端口或设备接口，灰度/彩色 STN-LCD或TFT-LCD接口，中断控制器，SPI 主/从控制器，I2C 主/从控制器，键盘扫描，可编程I/O端口，16位声音回放/编码，立体声耳机DAC/ADC（数/模转换）接口，10位触摸板ADC，内嵌480K SRAM和2048K ROM。（是Bit）
产品特点：
Product Features
■ μ’nSP 2.0 16-bit CPU with frequency up to 96MHz.
96MHz，还好~~
■ 30k*16 bits SRAM for programming or LCD frame buffers.
显示和主内存共用60K，希望能大部分用于显示。
■ 128K*16 bits ROM for embedded algorithm.
256KB的ROM~~能干什么？后台？
■ Programmable 7-band EQ.
可编程7段EQ，希望能自定义~~
■ Programmable 3D surround effecter.
这个~~3D环绕~~^_^|||
■ Static memory controller. (ROM/SRAM/NOR FLASH /NAND FLASH with ECC/checksum)
■ Four-channel DMA controller.
内存控制~~
■ STN-LCD controller which can support gray scale and color STN panel.
■ TFT-LCD controller which can RGB(5-6-5), serial delta RGB, serial stripe RGB, serial YUV, serial YCbCr, and CCIR656.
■ 4 PIP and scroll function is supported by TFT controller.
显示方面的，支持个硬卷屏~~
■ Thirty sources Interrupt Controller.
30个中断源。
■ Universal Serial Bus (USB) device and USB mini-host with built-in transceiver.
USB~~没说什么版本的~~估计是1.1没敢说~~
■ Watch-dog timer.
■ Real-time clock.
■ Six 16-bits timer.
看门狗和RTC，计时器什么的~~
■ SD/MMC memory interface.
SD/MMC支持~~
■ SPI master/slave interface.
■ I2C Interface.
■ Serial IO interface.
■ UART (asynchronous serial I/O) or IrDA interface.
不关我们的事的东西~~
■ 64 Programmable general I/O ports (GPIO) with pull-high/low control.
64个I/O接口~~
■ Key scan controller.
■ I2S output function which can be used for external DAC.
■ Power manager.
■ 3.0V to 1.8V Regulator.
电压转换？？
■ Low voltage reset.
希望这个低电自保护能做的好点~~不要动不动就重起~
■ USB transceiver.
估计这个芯片可以做那个数码相机的转存器，支持USB收发~~
■ High speed and low speed PLL.
■ 16-bits stereo DAC for audio playback.
■ Stereo headphone amplifier.
■ 16-bits stereo ADC for voice recording.
■ 10-bits ADC with 4 line-in, and touch-panel input. |
