... ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 1Ch DESCRIPTION The M27C202 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable ideally suited for micro- processor systems requiring large programs, in the application where the contents is stable and needs to be programmed only one time, and is or- ganised as 131,072 by 16 bits ...

... Standby Mode The M27C202 has a standby mode which reduces the supply current from 50mA to 100 A. The M27C202 is placed in the standby mode by applying a TTL 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 addi- tion, a 4.7 F bulk electrolytic capacitor should be used between V CC es. The bulk capacitor should be located near the power supply connection point.The purpose of the bulk capacitor is to overcome the voltage drop caused by the inductive effects of PCB traces.

... Sampled only, not 100% tested. Programming When delivered (and after each ‘1’s erasure for UV EPROM), all bits of the M27C202 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 ‘ ...

... Programming of multiple M27C202s in parallel with different data is also easily accomplished. Ex- cept for E, all like inputs including G of the parallel M27C202 may be common. A TTL low level pulse applied to a M27C202’s P input, with E low and V at 12.75V, will program that M27C202. A high PP level E input inhibits the other M27C202s from be- ing programmed ...
