Overview
M27V512 512 Kbit (64Kb x8) Low Voltage UV EPROM and OTP EPROM s LOW VOLTAGE READ OPERATION: 3V to 3.
6V FAST ACCESS TIME: 100ns LOW POWER CONSUMPTION: – Active Current 10mA at 5MHz – Standby Current 10µA 28 28 s s s s s PROGRAMMING VOLTAGE: 12.
75V ± 0.
25V PROGRAMMING TIME: 100µs/byte (typical) ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 3Dh 1 1 FDIP28W (F) PDIP28 (B) DESCRIPTION The M27V512 is a low voltage 512 Kbit EPROM offered in the two ranges UV (ultra viloet erase) and OTP (one time programmable).
It is ideally suited for microprocessor systems and is organized as 65,536 by 8 bits.
The M27V512 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 between battery recharges.
The FDIP28W (window ceramic frit-seal package) has transparent lid which allows the user to expose the chip to ultraviolet light to erase the bit pattern.
