This document describes the features and characteristics of Alliance Semiconductor's products, including the organization of the memory, sector architecture, power supply requirements, sector protection, high-speed access time, automated programming and erase algorithms, endurance, and low power consumption.
The AS29F200 is a 2 megabit, 5 volt only Flash memory organized as 256K bytes of 8 bits each or 128K words of 16 bits each. It is offered in JEDEC standard 44-pin SO and 48-pin TSOP packages and is designed to be programmed and erased in-system with a single 5.0V Vcc supply.
The device features flexible sector architecture allowing erase of any combination of sectors or the full chip, along with boot code sector architecture supporting top (AS29F200T) or bottom (AS29F200B) booting. It includes automated on-chip programming and erase algorithms, hardware RESET pin functionality, and low power consumption modes.
