General Description
M27W402 General Description
The M27W402 is a low voltage 4 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 262,144 by 16 bits.
The M27W402 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 FDIP40W (window ceramic frit-seal package) has a transparent lids which allow 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 M27W402 is offered in PDIP40, PLCC44 and TSOP40 (10 x 20 mm) packages.
