1 / 11 page AI00834B 13 A0-A12 P Q0-Q7 VPP VCC M27C64A G E VSS 8 Figure 1. Logic Diagram March 1995 M27C64A 64K (8K x 8) UV EPROM and OTP ROM VERY FAST ACCESS TIME: 150ns COMPATIBLE with HIGH SPEED MICROPROCESSORS, ZERO WAIT STATE LOW POWER “CMOS” CONSUMPTION: – Active Current 30mA – Standby Current 100 µA PROGRAMMING VOLTAGE: 12.5V ELECTRONIC SIGNATURE for AUTOMATED PROGRAMMING HIGH SPEED PROGRAMMING (less than 1 minute) DESCRIPTION The M27C64A is a high speed 65,536 bit UV eras- able and electrically programmable memory EPROM ideally suited for microprocessor systems requiring large programs. It is organized as 8,192 by 8 bits. The 28 pin Window Ceramic Frit-Seal Dual-in-Line package has transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern. Anew pattern can then be written to the device by following the programming procedure. For applications where the content is programmed only on time and erasure is not required, the M27C64A is offered in Plastic Leaded Chip Carrier package.
