描述 Description

DESCRIPTION
The µPD78324 is a 16/8-bit single-chip microcontroller that incorporates a high-performance 16-bit CPU. The µPD78324 is one of 78K/III series. The internal capacity is significantly increased compared with the conventional µPD78322.
A realtime pulse unit for realtime pulse control required in motor control, an A/D converter, a ROM, and a RAM have been integrated into one chip.
The µPD78324 incorporates 32K-byte mask ROM and 1024-byte RAM.
The µPD78323 is a ROM-less version of the µPD78324. Also, It is provided the µPD78P324 as an on-chip PROM product.FEATURES
● 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)
  
• Multiply/divide instructions (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 processing mode selectable
   (Vectored interrupt function, context switching function, and macro service function)
● Variety of peripheral hardware
  
• Realtime pulse unit
  
• 8-channel, 10-bit A/D converter
  
• Watchdog timer
● Powerful serial interface (with an on-chip dedicated baud rate generator)
  
• UART ····· 1 channel
  
• SBI (NEC Standard Serial Bus Interface)
  
• 3-wire serial I/O ····· 1 channelAPPLICATIONS
● Motor control devices
