... M27C512 1 Description The M27C512 is a 512 Kbit 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 65536 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 M27C512 has a standby mode which reduces the active current from 30mA to 100µA The M27C512 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 ...

... Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C512 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 M27C512s 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 M27C512's E input, with V program that M27C512. A high level E input inhibits the other M27C512s from being programmed. 2.8 Program Verify A verify (read) should be performed on the programmed bits to determine that they were correctly programmed ...

... Research shows that constant exposure to room level fluorescent lighting could erase a typical M27C512 in about 3 years, while it would take approximately 1 week to cause erasure when exposed to direct sunlight. If the M27C512 exposed to these types of lighting conditions for extended periods of time suggested that opaque labels be put over the M27C512 window to prevent unintentional erasure ...
