描述 Description

DESCRIPTION
The µPD7564A is a 4-bit single-chip microcomputer with a small number of ports in a small package, which is of low-order models, µPD7554 and 7564 sub-series in the µPD7500 series. With an on-chip serial interface, it performs efficient dispersion processing of a system as a sub-CPU for the 75X series or 78k series.
The µPD7564A has outputs to directly drive a triac and LEDs and allows selection among many types of input/output circuits using their respective mask options, sharply reducing the number of external circuits required.FEATURES
• 47 types of instructions
   (Subset of µPD7500H SET B)
• Instruction cycle Ceramic oscillation : 2.86 µs
   (in operation at 700 kHz, 5 V)
• Program memory (ROM) capacity: 1024 × 8 bits
• Data memory (RAM) capacity: 64 × 4 bits
• Test source: One external source and two internal sources
• 8-bit timer/event counter
• 15 I/O lines (Total output current of all pins: 100 mA)
  
• Can directly drive a triac and a LED: P80 to P82
  
• Can directly drive LEDs: P100 to P103 and P110 to P113
  
• Mask option function provided for every port
• 8-bit serial interface
• Standby (STOP/HALT) function
• Low supply voltage data retaining function for data memory
• Built-in ceramic oscillator for system clock
• Low power dissipation
• Single power supply (2.7 to 6.0 V)APPLICATIONS
  µPD7564A : PPCs, printers, VCRs, audio equipments, etc.
  µPD7564A(A) : Automotive and transportation equip ments, etc.
