DATA SHEET
MOS INTEGRATED CIRCUIT
µPD78052Y, 78053Y, 78054Y, 78055Y, 78056Y, 78058Y
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD78052Y, 78053Y, 78054Y, 78055Y, 78056Y, and 78058Y versions add the I2C bus control function to
the µPD78052, 78053, 78054, 78055, 78056, and 78058, and are suitable for application in AV products.
Various peripheral hardware such as 8-bit resolution D/A converter, timer, serial interface, real-time output port
and interrupt functions are incorporated.
The 78P058Y, a one-time PROM or EPROM version which can be operated in the same supply voltage as for
the mask ROM version, and various development tools are also available.
Detailed function descriptions, etc., are provided in the following User's Manual. Be sure to read it when
designing.
