The M27V512 is a low voltage 512 Kbit EPROM offered in the two ranges UV (ultra viloet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems and is organized as 65,536 by 8 bits.
The M27V512 operates in the read mode with a supply voltage as low as 3V. 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 FDIP28W (window ceramic frit-seal package) has 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 M27V512 is offered in PDIP28, PLCC32 and TSOP28 (8 x 13.4 mm) packages.
