... ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 41h DESCRIPTION The M27C4001 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 524,288 by 8 bits. ...

... The M27C4001 has a standby mode which reduc the supply current from 30mA to 100 A. The M27C4001 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-Q7 Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C4001 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 ...

... Ex- cept for E, all like inputs including G of the parallel M27C4001 may be common. A TTL low level pulse applied to a M27C4001’s E input, with V at 12.75V, will program that M27C4001. A high level E input inhibits the other M27C4001s from being programmed ...
