4MEG (52488
脳
8 Bits) Flash Memory
Preliminary
Overview
The LE28FV4001M, T, R Series are 4 MEG flash
memory products that feature a 542488-word
脳
8-bit
organization and 3.3 V single-voltage power supply
operation. CMOS peripheral circuits were adopted for
high speed, low power, and ease of use. The
LE28FV4001M also supports high-speed data rewriting
by providing a sector (256 bytes) erase function.
