... ELECTRONIC SIGNATURE – Manufacturer Code: 0020h – Device Code: 0044h DESCRIPTION The M27C4002 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable ideally suited for micro- processor systems requiring large programs and is organised as 262,144 words of 16 bits. ...

... The M27C4002 has a standby mode which re- DQ6 duces the supply current from 50mA to 100 A. The DQ7 M27C4002 is placed in the standby mode by ap plying a CMOS high signal to the E input. When in the standby mode, the outputs are in a high imped- ance state, independent of the G input. ...

... Q0-Q15 Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C4002 are in the ’1’ state. Data is introduced by selectively program- ming ’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 M27C4002s in parallel with different data is also easily accomplished. Except for E, all like inputs including G of the parallel M27C4002 may be common. A TTL low level pulse applied to a M27C4002’s E input, with V at 12.75V,will program that M27C4002. Ahigh PP level E input inhibits the other M27C4002s from being programmed ...

If the M27C4002 exposed ambient these types of lighting conditions for extended pe- riods of time suggested that opaque labels be put over the M27C4002 window to prevent uninten- tional erasure ...
