M28W320CB-90N1

The M28W320CB-90N1 is a kind of 32 Mbit non-volatile flash memory that can be erased electrically at the block level and programmed in-system on a Word-by-Word basis. The memory is organised as 2 Mbit by 16 bits. It is packaged in the TSOP48 (10 x 20mm).

There are some features of M28W320CB-90N1. First is fast access time which is 90 ns. Then is programming time which is 10s typical. Next is program/erase controller (P/E.C.). The fourth is common flash interface. The fifth is memory blocks. The sixth is block protection unprotection. The seventh is automatic stand-by mode. The eighth is program and erase suspend. The ninth is 100,000 program/erase cycles per block. The last one is about the security which contains 64-bit user Programmable OTP cells, 64-bit unique device identifier and one parameter block permanently lockable.
