1 / 12 page M27C64A 64 Kbit (8Kb x 8) UV EPROM and OTP EPROM March 1998 1/12 5V ± 10% SUPPLY VOLTAGE in READ OPERATION FAST ACCESS TIME: 150ns LOW POWER “CMOS” CONSUMPTION: – Active Current 30mA – Standby Current 100 µA PROGRAMMING VOLTAGE: 12.5V ± 0.25V HIGH SPEED PROGRAMMING (less than 1 minute) ELECTRONIC SIGNATURE – Manufacturer Code: 9Bh – Device Code: 08h DESCRIPTION The M27C64A is a 64Kbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for micro- processor systems requiring large programs and is organized as 8,192 by 8 bits. The FDIP28W (window ceramic frit-seal package) has transparent lid which 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. For applications where the content is programmed only on time and erasure is not required, the M27C64A is offered in PLCC32 package. AI00834B 13 A0-A12 P Q0-Q7 VPP VCC M27C64A G E VSS 8 Figure 1.
