description

The

TMS29F010

is

a

131 072

by

8-bit

(1048 576-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.
