8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD78011FY, 78012FY, 78013FY, 78014FY, 78015FY, 78016FY, and 78018FY are the products in the µPD78018FY
subseries within the 78K/0 series, and the products which is added the I2C bus control function to the µPD78018F subseries.
A one-time PROM or EPROM product µPD78P018FY capable of operating in the same power supply voltage as of the
mask ROM product and other development tools are also provided.
Functions are described in detail in the following User's Manual, which should be read when carring out design
work.
