description
The TMS29F002T/B is a 262 144 by 8-bit (2 097 152-bit), 5-V single-supply, programmable read-only memory
device that can be electrically erased and reprogrammed. This device is organized as 262 144 x 8 bits, divided
into seven sectors:
– One 16K-byte protected-boot sector
– Two 8K-byte sectors
– One 32K-byte sector
– Three 64K-byte 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
