LE28F4001T Datasheet | SANYO

Overview The LE28F4001 Series ICs are 524288-word × 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.
