M27V800 - STMicroelectronics

M27V800 8 Mbit 1Mb x8 or 512Kb x16 Low Voltage UV EPROM and OTP EPROM

The M27V800 is a low voltage 8 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 1 Mbit words of 8 bit or 512 Kbit words of 16 bit. The pinout is compatible with a 8 Mbit Mask ROM. Figure 1. Logic Dia.

Features

a 2 line control function which accommodates the use of multiple memory connection. The two line control function allows: a. the lowest possible memory power dissipation, b. complete assurance that output bus contention will not occur. 4/16 M27V800 Table 7.
