硬件连线参考:
1: Advance NAND flash(1KWords/2KBytes page size, 4/5 address cycle)
0: 8-bit bus width
1: 5 address cycle(NCON = 1)
1: Page=2KBytes(NCON = 1)
1: Advance NAND flash(1KWords/2KBytes page size, 4/5 address cycle)
0: 8-bit bus width
1: 5 address cycle(NCON = 1)
1: Page=2KBytes(NCON = 1)
打开K9F2G08U0的规格书进行信息的验证。如下图。验证结果说明硬件图3不正确,实际电路板NR5是不焊的。
注意:1 Device=2112Mbits。单位为bits即 =264Mbyte 哦!
