MOS INTEGRATED CIRCUIT
µPD78F4216A, 78F4218A, 78F4216AY, 78F4218AY
16-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD78F4216A/78F4218A and 78F4216AY/78F4218AY are products of µPD784216A/784218A,
784216AY/784218AY Subseries in the 78K/IV Series.
The µPD78F4216A/78F4218A have flash memory in place of the internal ROM of the µPD784216A/784218A. The
incorporation of flash memory allows a program to be written or erased while mounted on the target board.
The µPD78F4216AY/78F4218AY are based on the µPD78F4216A/78F4218A Subseries with the addition of a
multimaster-supporting I2C bus interface.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
