The M27C160 is a 16 Mbit EPROM that is suitable for microprocessor systems requiring large data or program storage. It has fast access time, low power consumption, can be erased by ultraviolet light, programmable once, and has an electronic signature.
The M27C160 is a 16 Mbit EPROM offered in UV (ultraviolet erase) and OTP (one‑time programmable) versions. It is available in PDIP42, PLCC44 and $044 packages and can be organized as either 2 Mbit × 8‑bit (byte‑wide) or 1 Mbit × 16‑bit (word‑wide). The device features low power consumption, a fast 70 ns access time, and a two‑line output control for efficient array operation.
The handbook provides detailed pin‑connection diagrams, absolute maximum ratings, electrical characteristics for both read and programming modes, and guidelines for system design such as decoupling and standby operation. Programming requires a 12.5 V + 0.25 V supply on the Vpp pin, and the device includes an electronic signature for identification.

The device requires a programming voltage of 12.5 V + 0.25 V on the Vpp pin.
It draws about 70 mA of active current at 8 MHz.
The device can be configured as byte‑wide or word‑wide, selected by the level on the BYTEVpp pin.
