PRELIMINARY DATA SHEET
MOS INTEGRATED CIRCUIT
µPD780053,780054,780055,780056,780058
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD780053,780054,780055,780056 and 780058 are members of the µPD780058 subseries in the 78K/0
series. These microcontrollers suppress the EMI (Electro Magnetic Interference) noise internally generated to the
lower level than the existing µPD78054 subseries. In addition, they have many peripheral hardware units such as an
8-bit resolution A/D converter, 8-bit resolution D/A converter, timers, serial interface, real-time output ports, and
interrupt functions.
A flash memory model that can operate on the same voltage as the mask ROM models, µPD78F0058, and various
development tools are now under development.
The funcitons are explaned in detail in the following User's Manuals. Be sure to read these manuals when
designing your system.
