LC665304A - Four-Bit Single-Chip Microcontrollers with 8/ 12/ and 16 KB of On-Chip ROM

Features

  • and Functions.
  • On-chip ROM capacitiy of 4, 6, 8, 12, and 16 kilobytes, and an on-chip RAM capacity of 512 × 4 bits.
  • Fully supports the LC66000 Series common instruction set (128 instructions).
  • I/O ports: 42 pins.
  • A sub-oscillator circuit can be used (option) This circuit allows power dissipation to be reduced by operating at lower speeds.
  • 8-bit serial interface: two circuits (can be connected in cascade to form a 16-bit interface).
  • Instruc.
