Introduction

FAST ACCESS TIME: 180ns EXTENDED TEMPERATURE RANGE SINGLE 5V SUPPLY VOLTAGE LOW STANDBY CURRENT: 35mA max TTL COMPATIBLE DURING READ and PROGRAM FAST PROGRAMMING ALGORITHM ELECTRONIC SIGNATURE PROGRAMMING VOLTAGE: 12V. The 65,536 bit UV erasable and electrically programmable memory EPROM. It is organized as 8,192 words by 8 bits. The M27C64A is housed a 28 pin Window Ceramic Frit-Seal Dual-in-Line package. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure.
