Notice for use
The construction of the one-time programmable microcomputer with a blank built-in PROM makes it
impossible for Sanyo to completely factory-test it before shipping. To probe reliability of the pro-
grammed devices, the screening procedure shown in the following figure should always be followed.
It is not possible to perform a writing test on the blank PROM. 100% yield, therefore, cannot be
guaranteed.
Keeping the dry packing
The environment must be held at a temparature of 30
°
C or less and a humidity level of 70% or less.
After opening the packing
After opening the packing, a controlled environment must be maintained until soldering.
The environment must be held at a temperature of 30
°
C or less and a humidity level of 70% or less.
Please solder within 96 hours.
a. Shipping with a blank PROM (Programming the data by yourself)
This microcomputer is provided DIP / QFP packages, but the condition before mounting is
different. Refer to the mounting procedure as follows.
