† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.


NOTES:
1. All voltage values are with respect to VSS.
2. The voltage on any input pin can undershoot to 2 V for periods less than 20 ns (see Figure 6).
3. The voltage on any input or output pin can overshoot to 7 V for periods less than 20 ns (see Figure 7).

The TMS29LF800T/B is a 1048576 by 8-bit/524288 by 16-bit (8388608-bit), 3-V single-supply, programmable read-only memory device that can be electrically erased and reprogrammed. This device is organized as 1024K by 8 bits or 512K 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.
