DATA SHEET

MOS INTEGRATED CIRCUIT

µPD78C14(A)

8-BIT SINGLE-CHIP MICROCONTROLLER (WITH A/D CONVERTER)

TheµPD78C14(A)isasingle-chip,CMOS8-bitmicrocontrollerinwhicha16-bitALU,aROM,aRAM,anA/Dconverter,

a multifunction timer/event counter, and a serial interface are all integrated. Moreover, a 48-Kbyte external expansion

memory (ROM/RAM) can be connected.

Since the µPD78C14(A) uses the CMOS construction, its operations are performed with low power consumption. By

using the standby function, functions such as data retention are performed with lower power consumption.

For details on functions, refer to the User’s Manual listed below. Please read it before starting design work.

87AD series µPD78C18 User’s Manual: IEU-1314
