2 INTRODUCTION TO NK-NUC980 BOARD
The NK-NUC980 is a development board based on an ARM® ARM926EJ-S microprocessor
NUC980DF61YC which has very rich peripherals to help users easily to design-in their products
or application systems.
The NK-NUC980 board uses NUC980DF61YC microprocessor run up to 300 MHz with built-in
64MB DDR2 memory, 16 KB I-cache, 16 KB D-cache and MMU, 16 KB embedded SRAM and
16.5 KB IBR (Internal Boot ROM) for system booting from USB, NAND flash, SD/eMMC and SPI
Flash, All functions of the NUC980DF61YC are placed on the board, including peripheral
interfaces such as memory (NAND, SPI, eMMC, SD), UART, IIS, Ethernet, USB (device, HOST),
CMOS sensor, SIM card, CAN, JTAG and EBI, Users can use it to develop and verify applications
to emulate the real behavior.
