Product Description

Summary description
The M27W401 is a low voltage 4 Mbit EPROM offered 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 organised as 524,288 by 8 bits.
The M27W401 operates in the read mode with a supply voltage as low as 2.7V at –40 to 85°C temperature range. The decrease in operating power allows either a reduction of the size of the battery or an increase in the time between battery recharges.
Features
■ 2.7V to 3.6V Supply Voltage in Read Operation
■ Access Time:
– 70 ns at VCC = 3.0V to 3.6V
– 80 ns at VCC = 2.7V to 3.6V
■ Pin Compatible with M27C4001
■ Low Power Consumption:
– 15 µA Max. Standby Current
– 15 mA Max. Active Current at 5 MHz
■ Programming Time 100 µs/byte
■ High Reliability CMOS Technology
– 2,000V ESD Protection
– 200 mA Latchup Protection Immunity
■ Electronic Signature
– Manufacturer Code: 20h
– Device Code: 41h
■ ECOPACK® packages available
