M27W512
512 Kbit (64Kb x 8) Low Voltage OTP EPROM
DATA BRIEFING
LOW VOLTAGE READ OPERATION: 2.7V to 3.6V FAST READ ACCESS TIME: 90ns at VCC = 3.0V to 3.6V 100ns at VCC = 2.7V to 3.6V PIN COMPATIBLE with M27C512 LOW POWER CONSUMPTION: 15µA max Standby Current 15mA max Active Current at 5MHz PROGRAMMING TIME 100µs/byte (typical) HIGH RELIABILITY CMOS TECHNOLOGY 2,000V ESD Protection 200mA Latchup Protection Immunity ELECTRONIC SIGNATURE Manufacturer Code: 20h Device Code: 3Dh DESCRIPTION The M27W512 is a low voltage 512 Kbit EPROM offered in the OTP range (one time programmable). It is ideally suited for microprocessor systems and is organized as 65,536 by 8 bits. The M27W512 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. The M27W512 is offered in PLCC32 and TSOP28 (8 x 13.4 mm) packages. Signal Names
