... ELECTRONIC SIGNATURE – Manufacturer Code: 9Bh – Device Code: 08h DESCRIPTION The M27C64A is a 64Kbit 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 organized as 8,192 by 8 bits. ...

... DEVICE OPERATION The modes of operation of the M27C64A are listed in the Operating Modes table. A single power sup- ply is required in the read mode. All inputs are TTL levels except for V Signature. Read Mode The M27C64A has two control functions, both of which must be logically active in order to obtain data at the outputs ...

... Standby Mode The M27C64A has a standby mode which reduces the active current from 30mA to 100µA. The M27C64A 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 imped- ance state, independent of the G input. ...

... Sampled only, not 100% tested. Programming When delivered (and after each erasure for UV EPROM), all bits of the M27C64A 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 ...

... Except for E, all like inputs including G of the parallel M27C64A may be common. A TTL low level pulse ++ Addr applied to a M27C64A P input, with E low and V at 12.5V, will program that M27C64A. A high level E input inhibits the other M27C64A from being pro- grammed. ...
