M27V160 Datasheet | STMicroelectronics

The M27V160 is a low voltage 16 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage. It is organised as either 2 Mbit words of 8 bit or 1 Mbit words of 16 bit. The pin-out is patible with a 16 Mbit Mask ROM. The M27V160 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 FDIP42W (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 rapidly to the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27V160 is offered in PDIP42 and SO44 packages. PDIP42 (B) Figure 1.
