Description

The UPD780053,780054,780055,780056 and 780058 are members of the mPD780058 subseries in the 78K/0 series. These microcontrollers suppress the EMI (Electro Magnetic Interference) noise internally generated to the lower level than the existing UPD78054 subseries. In addition, UPD780053,780054,780055,780056 and 780058 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 of UPD780053,780054,780055,780056 and 780058 can operate on the same voltage as the mask ROM models, mPD78F0058, and various development tools are now under development.
