Jameco Part Number 39933 M27128A NMOS 128 Kbit (16Kb x 8) UV EPROM NOT FOR NEW DESIGN s FAST ACCESS TIME: 200ns s EXTENDED TEMPERATURE RANGE s SINGLE 5 V SUPPLY VOLTAGE s LOW STANDBY CURRENT: 40mA max s TTL COMPATIBLE DURING READ and PROGRAM s FAST PROGRAMMING ALGORITHM s ELECTRONIC SIGNATURE s PROGRAMMING VOLTAGE: 12V 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. 28 1 FDIP28W (F) Figure 1.
