D78C10A
Overview
The µPD78C11A is a CMOS 8-bit microprocessor which can integrate 16-bit ALU, ROM, RAM, an A/D converter, a multi-function timer/event counter, and a general-purpose serial interface into a single chip, then expand the memory (ROM/RAM) up to 60K bytes externally. The µPD78C10A is a ROM-less product of the µPD78C11A, and can directly address the external memory up to 64k bytes.
- Abundant 159 types of instructions : 87AD series instruction set, multiplication/division instructions, 16-bit operation instructions
- Instruction cycle : 0.8 µs (at 15 MHz operation)
- On-chip ROM : 4096W × 8 (µPD78C11A), 8192W × 8 (µPD78C12A) Non (µPD78C10A)
- On-chip RAM : 256W × 8
- High-precision 8-bit A/D converter : 8 analog inputs
- General-purpose serial interface : Asynchronous, synchronous, I/O interface mode
- Multi-function 16-bit timer/event counter
- Two 8-bit timers
- I/O lines : 32 (µPD78C10A), 44 (µPD78C11A, 78C12A)
- Interrupt function (external - 3, internal - 8) : Non-maskable interrupt × 1, maskable interrupt × 10
