UV-EPROM M27C256B-12F1 Module

The M27C256Bis a 256 KbitEPRO Mofferedin the two ranges UV (ultra violet erase) and OTP (one-time programmable). It is ideally suited for microprocessor systems and is organized as 32,768 by 8 bits. The FDIP28W (window ceramic frit-seal package) has a transparent lid which 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.
For applications where the content is programmed only one time and erasure is not required, the M27C256B is offered in PDIP32, PLCC32, and TSOP28 (8 x 13.4 mm) packages.
