The 78K0R/Lx3 microcontrollers are 16-bit single-chip microcontrollers that include the 78K0R CPU core and peripheral functions such as ROM/RAM, LCD controller/driver, A/D converter, D/A converter, operational amplifier, multifunctional serial interfaces, multifunctional timers, real-time counter, and watchdog timer.

• Minimum instruction execution time can be changed from high speed (0.05 µs: @ 20 MHz operation with high-speed system clock) to ultra low-speed (61 µs: @ 32.768 kHz operation with subsystem clock)
• General-purpose register: 8 bits × 32 registers (8 bits × 8 registers × 4 banks)
• On-chip single-power-supply flash memory (with prohibition of chip erase/block erase/writing function)
• Self-programming (with boot swap function/flash shield window function)
• On-chip debug function
• On-chip power-on-clear (POC) circuit and low-voltage detector (LVI)
• On-chip watchdog timer (can operate on dedicated internal low-speed oscillation clock)
• On-chip multiplier/divider (16 bits × 16 bits)
• On-chip key interrupt function
• On-chip clock output/buzzer output controller
• On-chip BCD adjustment
• I/O ports: 70 (N-ch open drain: 4)
• Timer: 10 channels
  • 16-bit timer: 8 channels
  • Watchdog timer: 1 chann
