UPD78C12A
Description
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.
Key Features
- 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)
- 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
- Interrupt function (external - 3, internal - 8) : Non-maskable interrupt × 1, maskable interrupt × 10
- Standby function : HALT mode, hardware/software STOP mode
- Zero-cross detection function : (2 inputs)
