... A with low voltage operation V CC Characteristics table for details. The M27W202 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, all bits of the M27W202 are in the ’1’ state. Data is introduced by selectively pro- gramming ’0’s into the desired bit locations. Al- though only ’0’s will be programmed, both ’1’s and ’ ...

... Programming of multiple M27W202s in parallel with different data is also easily accomplished. Ex- cept for E, all like inputs including G of the parallel M27W202 may be common. A TTL low level pulse applied to a M27W202’s P input, with E low and V at 12.75V, will program that M27W202. A high PP level E input inhibits the other M27W202s from be- ing programmed ...

... On-Board Programming The M27W202 can be directly programmed in the application circuit. See the relevant Application Note AN620. Electronic Signature The Electronic Signature (ES) mode allows the reading out of a binary code from an EPROM that will identify its manufacturer and type. This mode is intended for use by programming equipment to automatically match the device to be programmed with its corresponding programming algorithm ...
