1 / 15 page M27V102 1 Mbit (64Kb x 16) Low Voltage UV EPROM and OTP EPROM May 1998 1/15 AI01912 16 A0-A15 P Q0-Q15 VPP VCC M27V102 G E VSS 16 Figure 1. Logic Diagram LOW VOLTAGE READ OPERATION: 3V to 3.6V FAST ACCESS TIME: 90ns LOW POWER CONSUMPTION: – Active Current 15mA at 5MHz – Standby Current 20 µA PROGRAMMING VOLTAGE: 12.75V ± 0.25V PROGRAMMING TIME: 100 µs/byte (typical) ELECTRONIC SIGNATURE – Manufacturer Code: 0020h – Device Code: 008Ch DESCRIPTION The M27W102 is a low voltage 1 Mbit EPROM offeredin the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage and is organized as 65,536 words by 16 bits. The M27V102 operates in the read mode with a supply voltage as low as 3V. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time be- tween battery recharges. The FDIP40W (window ceramic frit-seal package) has a 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.
