LC86P6032 Datasheet, PDF (21/22 Pages) Sanyo Semicon Device – 8-Bit Single Chip Microcontroller with One-Time PROM

Notice for use
LC86P6032
• 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.
• Should be stored in dry conditions (QFP type only)
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 (QFP type only)
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 8 hours.
