... ELECTRONIC SIGNATURE: – Manufacturer Code 20h – Device Code: 32h DESCRIPTION The M27C320 Mbit EPROM offered in the OTP range (one time programmable ideally suited for microprocessor systems requiring large data or program storage organised as either 4 MWords of 8 bit or 2 MWords of 16 bit. The pin- out is compatible with the 32 Mbit Mask ROM ...

... DEVICE OPERATION The operating modes of the M27C320 are listed in the Operating Modes Table. A single power supply is required in the read mode. All inputs are TTL compatible except for V Electronic Signature. Read Mode The M27C320 has two organisations, Word-wide and Byte-wide. The organisation is selected by the signal level on the BYTE pin ...

... Standby Mode The M27C320 has standby mode which reduces the supply current from 50mA to 100 A. The M27C320 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. ...

... In addition, a 4.7 F electrolytic capacitor should be used between V eight devices. This capacitor should be mounted near the power supply connection point. The pur- pose of this capacitor is to overcome the voltage drop caused by the inductive effects of PCB trac- es. M27C320 Min Max Unit ...

... Ex- cept for E, all like inputs including G of the parallel M27C320 may be common. A TTL low level pulse applied to a M27C320’s E input and V will program that M27C320. A high level E input in- hibits the other M27C320s from being pro- grammed. Program Verify ...
