Recommended screening conditions
Before one-time writing of microcontroller programs to PROM, high temperature aging is recommended as a
screening process for chips before they are mounted.
The following diagram shows the flow of the screening process.
About writing yields
The nature of chips before one-time writing of microcontroller programs to PROM prevents the use of all-bit
writing tests. Therefore it is not possible to guarantee writing yields of 100% in some cases.
