1 / 15 page 1/15 May 1998 M27V101 1 Mbit (128Kb x 8) Low Voltage UV EPROM and OTP EPROM s LOW VOLTAGE READ OPERATION: 3V to 3.6V s FAST ACCESS TIME: 90ns s LOW POWER CONSUMPTION: – Active Current 15mA at 5MHz – Standby Current 20 µA s PROGRAMMING VOLTAGE: 12.75V ± 0.25V s PROGRAMMING TIME: 100 µs/byte (typical) s ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 05h DESCRIPTION The M27V101 is a low voltage 1 Mbit EPROM of- fered in 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 131,072 by 8 bits. The M27V101 operates in the read mode with a supply voltage as low as 3V. The decrease in op- erating power allows either a reduction of the size of the battery or an increase in the time between battery recharges. The FDIP32W (window ceramic frit-seal package) has a transparent lid which allow the user to ex- pose the chip to ultraviolet light to erase the bit pat- tern. Figure 1.
