Alliance Memory NOR 8Mbit Parallel Flash Memory 48-Pin TSOP, AS29CF800B-55TIN

The Alliance Memory 8Mbit 5.0 volt-only Flash memory is organized as 1048576 bytes of 8 bits or 524288 words of 16 bits, with data appearing on I/O0 to I/O7 in 8-bit mode and on I/O0 to I/O15 in 16-bit mode. Offered in a 48-pin TSOP package, it is designed for in-system programming using a standard 5.0V VCC supply, eliminating the need for a 12.0V VPP during write or erase operations. It is also compatible with standard EPROM programmers. The device features a toggle bit, I/O6, which indicates whether an embedded program or erase operation is in progress or if the device is in erase suspend mode.
