The AMIC A29L400A Series is an 4Mbit CMOS Flash Memory organized as 512K x 8 bits or 256K x 16 bits. It features a single power supply operation with a voltage range of 2.7 to 3.6 volts for read/write operations, making it suitable for battery-powered applications and compatibility with high-performance microprocessors.
The device includes flexible sector architecture allowing any combination of sectors to be erased or protected. Key features include embedded algorithms for automatic erase and program verification, data polling and toggle bits for status detection, and hardware reset capabilities. It is offered in 44-pin SOP, 48-pin TSOP (I), and 48-ball TFBGA packages.
