27128 - NMOS 128K 16K x 8 UV EPROM

General Description

The M27128A is a 131,072 bit UV erasable and electrically programmable memory EPROM.

It is organized as 16,384 words by 8 bits.

The M27128A is housed in a 28 Pin Window Ceramic Frit-Seal Dual-in-Line package.

Key Features

  • a 2 line control function which accommodates the use of multiple memory connection. The two line control function allows: a. the lowest possible memory power dissipation, b. complete assurance that output bus contention will not occur. 2/10 M27128A DEVICE.

M27128A NMOS 128K (16K x 8) UV EPROM FAST ACCESS TIME: 200ns EXTENDED TEMPERATURE RANGE SINGLE 5 V SUPPLY VOLTAGE LOW STANDBY CURRENT: 40mA max TTL COMPATIBLE DURING READ and PROGRAM FAST PROGRAMMING ALGORITHM ELECTRONIC SIGNATURE PROGRAMMING VOLTAGE: 12V 28 1 FDIP28W (F) DESCRIPTION The M27128A is a 131,072 bit UV erasable and electrically programmable memory EPROM. It is organized as 16,384 words by 8 bits. The M27128A is housed in a 28 Pin Window Ceramic Frit-Seal Dual-in-Line package. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can then be written to the device by following the programming procedure. Figure 1.
