Overview
The LE28C1001M, T series ICs are 1 MEG flash memory products that feature a 131072-word ×8-bit organization and 5 V single-voltage power supply operation. CMOS peripheral circuits are adopted for high speed, low power dissipation, and ease of use. A 128-byte page rewrite function provides rapid data rewriting.
