Description

The TC574200D is a 262,144 word x 16 bit CMOS ultraviolet light erasable and electrically programmable read only memory. It

is organized as either 256K words by 16 bits or 512K words by 8 bits.

The TC574200D is compatible with the 40-pin 4M bit Mask ROM and is available in a 40-pin standard cerdip package. The

TC574200D is fabricated using CMOS technology. Advanced circuit techniques result in both high speed and low power features

with access times of 100ns/120ns/150ns and a maximum operating current of 70mA/10MHz.

The programming time of the TC574200D (except for EPROM programmer overhead) is only 28 seconds when using the high

speed programming algorithm.
