... ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 3Dh 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 applica- tions where fast turn-around and pattern experi- mentation are important requirements and is organized as 65,536 by 8 bits ...

... Standby Mode 8 A2 The M27C512 has a standby mode which reduces the active current from 30mA to 100 A The M27C512 is placed in the standby mode by apply- ing 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 1 ...

... Q0-Q7 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 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. The only way to change a ’ ...

... M27C512 in about 3 years, while it would take approximately 1 week to cause erasure when ex- posed 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 ...
