===========================================================
We are purchased LH79524 Zoom Starter Development Kit and hope for your support.
Our team developing device based on CPU SHARP LH79525 + Flash SAMSUNG K9F1G08U0A:
- In device scheme portC bits 4:7 (contacts A20:A23) configured to value 0x5h (boot from NAND, 8 bit address, 4 byte).
- In device scheme nSC0 is set to 1 and nCS1 is not set.
Does CPU SHARP LH79525 support NAND flash SAMSUNG K9F1G08U0A ?
* flash datasheet avaible by this url: (
http://www.datasheets.org...php?article=1880647)
If, yes:
====
Please help us to initialize CPU SHARP LH79525 + Flash SAMSUNG
K9F1G08U0A as was written before for CPU SHARP LH79524 and flash SHARP LH28F128SPHTD-PTL12.
If, No:
====
Please advise us what type of flash to use, where to buy (how much), how to configure initialization.
* Our need in > 64 MB flash memory (NOR or NAND).
with best regards and
big hope for your support.
