8. Recommended Screening Conditions

High-temperature aging is recommended as the pre-assembly screening procedure for a product with a blanked

OTPROM microcomputer program.

9. Programming Yields

All bits cannot be programmed at Fujitsu shipping test to a blanked OTPROM microcomputer, due to its nature.

For this reason, a programming yield of 100% cannot be assured at all times.

10.Fluctuations in Supply Voltage

Although the assured VCC supply voltage operating range is as specified, sudden fluctuations even within this

range may cause a malfunction. Therefore, the voltage supply to the IC should be kept as constant as possible.

The VCC ripple (P-P value) at the supply frequency (50 to 60 Hz) should be less than 10% of the typical VCC

value, or the coefficient of excessive variation should not be more than 0.1 V/ms instantaneous change when

power is supplied.
