M27W202

The M27W202 is a low voltage 2 Mbit EPROM offered in the two range UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage and is organised as 131,072 by 16 bits.

The M27W202 operates in the read mode with a supply voltage as low as 2.7V at 40 to 85°C temperature range. 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 M27W202(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 application M27W202 where the content is programmed only one time and erasure is not required, the M27W201 is offered in PDIP40, PLCC44 and TSOP40 (10 x 14 mm) packages.
