Additional Information

UV EPROM and OPT EPROM ICs
256Kbit (32Kb x 8)

We generally do not offer socket pulls however we made an exception for these ICs. They have been cleaned and erased and are available at a fraction of the original cost.

The M27C256B is a 256 Kbit EPROM which comes in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is organized as 32,768 by 8 bits. The clear window on the FDIP28W (window ceramic frit-seal package) lets you to expose the chip to ultraviolet light to erase the bit pattern.

Features:
- 5V � 10% supply voltage in Read operation
- Speed: 150ns
- Low power consumption:
-� Active Current 30mA at 5MHz
-� Standby Current 100μA
- Programming voltage: 12.75V � 0.25V
- Programming time: 100μs/Word
- Electronic signature
-� Manufacturer Code: 20h
-� Device Code: 8Dh
