Preliminary
Overview
The LE28F4001 Series ICs are 524288-word
脳
8-bit flash
memory products that support on-board reprogramming
and feature 5 V single-voltage power supply operation.
CMOS peripheral circuits were adopted for high speed,
low power, and ease of use. These products support a
sector (256 bytes) erase function for fast data rewriting.
