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

DESCRIPTION

The µPD78C11A(A) is a CMOS 8-bit microcomputer that features single-chip integration of a 16-bit ALU,

ROM, RAM, an A/D converter, a multifunctional timer/event counter, and a universal serial interface, as well

as up to 60 Kbytes of expandable external memory (ROM/RAM). The µPD78C10A(A) is the ROMless version

of the µPD78C11A(A) which can directly address up to 64 Kbytes of external memory. The µPD78C12A(A) is

a version of the µPD78C11A(A) that has greater on-chip ROM capacity and is expandable to up to 56 Kbytes

of external memory (ROM/RAM). The µPD78C10A(A), µPD78C11A(A), and µPD78C12A(A) all use CMOS

technology to enable low-power operation and they also feature standby functions to enable data retention

and other operations using very low power consumption.

In addition, the µPD78CP14(A) and 78CP18(A) are available as on-chip PROM versions appropriate for

evaluating and prototyping during system development as well as for early development of application sets

and low-volume production.

Detailed functional descriptions are provided in the following User’s Manual. This manual is required

reading for design work.

• Interrupt functions (3 external, 8 internal): 1 nonmaskable interrupt and 10 maskable interrupts

• Standby functions: HALT mode and hardware/software STOP mode

• Zero-cross detection function: 2 inputs

• On-chip mask optional pull-up resistors are available (for ports A, B, and C on µPD78C11A(A) or 78C12A(A)

only)

Caution Mask options are not available on the µPD78C10A(A).
