Description
The TC57H1000AD/TC57H1001AD is a 131,072 word x 8 bit CMOS ultraviolet light erasable and electrically programmable
read only memory.
The TC57H1000AD has a JEDEC standard pin configuration while the TC57H1001AD is compatible with the 28-pin 1M bit
Mask ROM. Both products are available in a 32-pin standard cerdip package.
The TC57H1000AD/TC57H1001AD is fabricated using CMOS technology. Advanced circuit techniques result in both high
speed and low power features with a maximum operating current of 40mA/11.8MHz and access times of 85ns/100ns.
(except for EPROM programmer overhead) is only 14 seconds
The programming time of the TC57H1000AD/TC57H1001AD
when using the high speed programming algorithm.
