N9H31K51IFC

The N9H31 series targeted for general purpose 32-bit microcontroller embeds an outstanding CPU core ARM926EJ-S, runs up to 300 MHz, with 16 KB I-cache, 16 KB D-cache and MMU, 56KB embedded SRAM and 16 KB IBR (Internal Boot ROM) for booting from USB, NAND and SPI FLASH.

The N9H31 series integrates USB 2.0 HS HOST/Device controller with HS transceiver embedded, TFT type LCD controller, 2D graphics engine, I2S I/F controller, SD/MMC/NAND FLASH controller, GDMA and 4 channels 12-bit ADC controller with resistance touch screen functionality. It also integrates UART, SPI/MICROWIRE, I2C, LIN, PWM, Timer, WDT/Windowed-WDT, GPIO, Keypad, Smart Card I/F, 32.768 KHz XTL and RTC (Real Time Clock).

Here, N9H31 series support 10/100 Mb Ethernet MAC controllers and further support CAN BUS interface for connectivity. In addition, it also integrates a DRAM I/F that runs up to 150 MHz with supporting  DDR2 type SDRAM. To reduce system complexity while cutting the BOM cost, the N9H31 series provides MCP (Multi-Chip Package) to ensure higher performance and to minimize the system design efforts.
