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 programmed 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 temperature of 30
°
C or less and a humidity level of 70% or less.
After opening the packing
The preparation procedures shown in the following figure should always be followed prior to mounting the packages on the
substrate. Note that the QFP package should be heat-soaked for 12 hours at 125
°
C immediately prior to mounting (This
baking is called pre-baking). After pre-baking, 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 24 hours.
