D78320L
Overview
The µPD78322 is a 16-/8-bit single-chip microcontroller that incorporates a high-performance 16-bit CPU. The µPD78322 is one of 78K/III series.
- Internal 16-bit architecture and external 8-bit data bus
- High-speed processing by pipeline control and instruction prefetch
- Minimum instruction execution time: 250 ns (with 16 MHz external clock in operation)
- Instruction set suitable for control operations (µPD78312 upward compatible)
- Multiplication/division instruction (16 bits × 16 bits, 32 bits ÷ 16 bits)
- Bit manipulation instruction
- String instruction, etc.
- On-chip high-function interrupt controller
- 3-level priority specifiable
- 3-type interrupt servicing mode selectable (Vectored interrupt function, context switching function, and macro service function)
