... M27C801 1 Description The M27C801 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable ideally suited for applications where fast turn-around and pattern experimentation are important requirements and is organized as 1,048,576 by 8 bits. The FDIP32W (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 M27C801 has a standby mode which reduces the supply current from 35mA to 100µA. The M27C801 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 GV input ...

... PCB traces. 2.5 Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C801 are in the '1' state. Data is introduced by selectively programming '0's into the desired bit locations. Although only '0' will be programmed, both '1's and '0's can be present in the data word. The only way to change die exposure to ultraviolet light (UV EPROM) ...

... Program Inhibit Programming of multiple M27C801s in parallel with different data is also easily accomplished. Except for E, all like inputs including GV common. A TTL low level pulse applied to a M27C801's E input, with V program that M27C801. A high level E input inhibits the other M27C801s from being programmed. ...

... Research shows that constant exposure to room level fluorescent lighting could erase a typical M27C801 in about 3 years, while it would take approximately 1 week to cause erasure when exposed to direct sunlight. If the M27C801 exposed to these types of lighting conditions for extended periods of time suggested that opaque labels be put over the M27C801 window to prevent unintentional erasure ...
