... M27W032 SUMMARY DESCRIPTION The M27W032 Mbit (2Mb x16) non-volatile, One Time Programmable (OTP), FlexibleROM™ Memory. Read operations can be performed using a single low voltage (2.7 to 3.6V) supply. Program operations require an additional V 12.6V) power supply. On power-up the memory defaults to Read mode where it can be read in the same way as a ROM or EPROM ...

... M27W032 COMMAND INTERFACE All Bus Write operations to the memory are inter- preted by the Command Interface. Commands consist of one or more sequential Bus Write oper- ations. Failure to observe a valid sequence of Bus Write operations will result in the memory return- ing to Read mode. The long command sequences are imposed to maximize data security ...
