The A29040B Series from AMIC Technology is a 5.0 V-only CMOS flash memory organized as 524,288 bytes of 8 bits and divided into eight uniform sectors of 64 Kbytes each. It is offered in 32-pin P-DIP, PLCC, and TSOP (Forward type) packages and is designed to be programmed in-system from the standard 5.0 V VCC supply.
The datasheet covers features, general description, pin configurations, a block diagram, pin descriptions, absolute maximum ratings, operating ranges, and device bus operations. It also documents access times of 55, 70, and 90 ns, embedded program and erase algorithms, hardware sector protection, Erase Suspend/Erase Resume, and data polling and toggle-bit status.
