Overview

The LE28CV1001M, T Series ICs are 1 MEG flash memory products that feature a 131072-word × 8-bit organization and 3.3 V single-voltage power supply operation. CMOS peripheral circuits are adopted for high speed, low power, and ease of use. A 128-byte page rewrite function provides rapid data rewriting.
