4MEG (52488 × 8 Bits) Flash Memory
Preliminary Overview
The LE28FV4001M, T, R Series are 4 MEG flash memory products that feature a 542488-word × 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.
