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. 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.
Unused devices should be kept in the dry atmosphere such as inside of desiccator or dry these up before assembling on the
board.
