DESCRIPTION
The TC571000D/TC571001D is a 131,072 word x 8 bit CMOS ultraviolet light erasable
and electrically programmable read only memory.
The TC571000D is JEDEC standard pin configuration and the TC571001D is compatible with
28 pin 1M bit Mask ROM. Both products are packed in 32 pin standard cerdip package.
TC571000D/TC571001D is fabricated with the CMOS technology. Advanced circuit tech-
niques provide both high speed and low power features with a maximum operating current
of 30mA/6.7MHz and access time of 150ns/200ns/250ns.
The programming times of the TC571000D/TC571001D except overhead times of EPROM pro-
grammer is only 14 seconds by using the high speed programming algorithm.
