1 / 13 page 1/13 May 1998 M27V405 4 Mbit (512Kb x 8) Low Voltage OTP EPROM s LOW VOLTAGE READ OPERATION: 3V to 3.6V s FAST ACCESS TIME: 120ns s LOW POWER CONSUMPTION: – Active Current 15mA at 5MHz – Standby Current 20µA s PROGRAMMING VOLTAGE: 12.75V ± 0.25V s PROGRAMMING TIMES: – Typical 48sec. (PRESTO II Algorithm) – Typical 27sec. (On-Board Programming) s PIN COMPATIBLE with the 4 Mbit, Single Voltage Flash Memory s ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: B4 DESCRIPTION The M27V405 is a low voltage 4 Mbit EPROM of- fered in the OTP range (one time programmable). It is ideally suited for microprocessor systems re- quiring large data or program storage and is orga- nised as 524,288 by 8 bits. The M27V405 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. PLCC32 (K) TSOP32 (N) 8 x 20 mm Figure 1.
