... M27C64A 1 Summary description The M27C64A is a 64Kbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable ideally suited for microprocessor systems requiring large programs and is organized as 8,192 by 8 bits. 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 ...

... Standby mode The M27C64A has a standby mode which reduces the active current from 30mA to 100µA. The M27C64A is placed in the standby mode by applying a CMOS high signal to the E input. When in the standby mode, the outputs are in a high impedance state, independent of the G input ...

... Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C64A are in the "1" state. Data is introduced by selectively programming "0"s into the desired bit locations. Although only "0"s will be programmed, both "1"s and "0"s can be present in the data word. ...

... Programming of multiple M27C64A in parallel with different data is also easily accomplished. Except for E, all like inputs including G of the parallel M27C64A may be common. A TTL low level pulse applied to a M27C64A P input, with E low and V will program that M27C64A. A high level E input inhibits the other M27C64A from being programmed ...
