description
The TMS29F010 is a 131072 by 8-bit
(1048576-bit), 5-V single-supply, programmable
read-only memory device that can be electrically
erased and reprogrammed. This device is
organized as eight independent 16K-byte sectors
and is offered with access times between 70 ns
and 120 ns.
An on-chip state machine controls the program and erase operations. The embedded byte-program and
sector/chip-erase functions are fully automatic. The command set is compatible with that of JEDEC 1M-bit
EEPROMs. Data-protection of any sector combination is accomplished using a hardware sector-protection
feature.
Device operations are selected by writing JEDEC-standard commands into the command register using
standard microprocessor write timings. The command register acts as an input to an internal-state machine that
interprets the commands, controls the erase and programming operations, outputs the status of the device,
outputs data stored in the device, and outputs the device algorithm-selection code. On initial power-up
operation, the device defaults to the read mode.
The TMS29F010 is offered in a 32-pin plastic leaded chip carrier (FM suffix) using 1.27-mm (50-mil) lead pitch.
