Description
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 channel
- Real-time counter: 1 channel
- Serial interface
- CSI: 2 channels/UART: 1 channel
- CSI: 1 channel/UART: 1 channel/simplified I2C: 1 channel
- CSI: 1 channel/UART: 1 channel/simplified I2C: 1 channel
- UART (LIN-bus supported): 1 channel
- I2C: 1 channel
- 10-bit resolution A/D converter (AVREF0 = 2.3 to 5.5 V): 8 channels
- 8-bit resolution D/A converter (AVREF1 = 1.8 to 5.5 V): 2 channels
- Power supply voltage: VDD = 1.8 to 5.5 V
- Operating ambient temperature: TA = -40 to +85°C
