The (4194304-bit), 5-V single-supply, programmable read-only memory that can be electrically erased and reprogrammed. This device is organized as eight independent 64K-byte sectors and is offered with access times between 60 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 4M-bit EEPROMs. A suspend / resume feature allows access to unaltered memory sectors during a sector-erase operation. 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 input to an internal-state machine that interprets the commands, controls the erase and programming operations, and outputs the status of the device, the data stored in the device, and the device algorithm-selection code. On initial power-up operation, the device defaults to the read mode. The TMS29F040 is offered a 32-pin plastic leaded chip carrier (FM suffix) using 1.27-mm (50-mil) lead pitch and a 32-pin thin small-outline package (DD suffix).
