The

µPD78C14(A) is a single-chip, CMOS 8-bit microcontroller in which a 16-bit ALU, a ROM, a RAM, an A/D converter,

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.
