Description
The “78K0R/Kx3-L microcontrollers” incorporate a high-performance 16-bit 78K0R CPU core and realize low power consumption that make them suitable for low power, battery-operated applications.
- 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)
- ROM, RAM capacities
- Flash ROM 64KB Ram 3 KB 78K0R/KE3-L – 64 Pins
- On-chip internal high-speed oscillation clocks
- 20 MHz Internal high-speed oscillation clock: 20 MHz (TYP.)
- 8 MHz Internal high-speed oscillation clock: 8 MHz (TYP.)
- 1 MHz Internal high-speed oscillation clock: 1 MHz (TYP.)
- 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 (operable with the dedicated internal low-speed oscillation clock)
- On-chip multiplier/divider (16 bits × 16 bits, 32 bits ÷ 32 bits)
