This document describes the features and characteristics of the A29040 series 512K x 8-bit CMOS 5.0 Volt-only Uniform Sector Flash Memory for 5.0V ± 10% read and write operations.
The document describes the A29040 Series, which is a 512 Kbyte (512K X 8 Bit) CMOS Flash Memory organized into eight uniform sectors of 64 Kbytes each. The device operates on a single 5.0 volt power supply for both read and write operations, eliminating the need for an additional programming voltage.
