Additional Details

The A29L400ATV-70F operates from a single 3V power supply, making it suitable for low-power applications. The device supports a sector erase architecture, allowing individual sectors to be erased and reprogrammed without affecting other sectors. It also features an erase suspend/resume capability, which allows the erase operation to be interrupted so that data can be read from other sectors of the memory. The embedded erase and program algorithms simplifies the memory programming process.
