TMS29F800B

The TMS29F800T/B is an 1048576 by 8-bit/524288 by 16-bit (8388608-bit), 5-V single-supply, programmable
read-only memory device that can be electrically erased and reprogrammed.

This device is organized as 1048576 by 8 bits or 524288 by 16 bits, divided into 19 sectors:
One 16K-byte/8K-word boot sector
Two 8K-byte/4K-word sectors
One 32K-byte/16K-word sector
Fifteen 64K-byte/32K-word sectors
Any combination of sectors can be marked as read-only or erased. Full-chip erasure is also supported.
Sector data protection is afforded by methods that can disable any combination of sectors from write or read
operations using standard programming equipment. An on-chip state machine provides an on-board algorithm
that automatically pre-programs and erases any sector before it automatically programs and verifies program
data at any specified address. The command set is compatible with that of the Joint Electronic Device
Engineering Council (JEDEC) standards and is compatible with the JEDEC 8M-bit electrically erasable,
programmable read-only memory (EEPROM) command set. A suspend/resume feature allows access to
unaltered memory blocks during a section-erase operation. All outputs of this device are TTL-compatible.
Additionally, an erase/suspend/resume feature supports reading data from, or programming data to, a sector
that is not being erased.
