Description
78K0/Kx2 microcontrollers are the next generation of the low pin count 78K0S/Kx1+ microcontrollers and provide various safety features such as flash only lineups including OSC, and comprehensive & low cost development tools.
- Minimum instruction execution time can be changed from high speed (0.1 µs: @ 20 MHz operation with high-speed system clock) to ultra low-speed (122 µs: @ 32.768 kHz operation with subsystem clock)
- General-purpose register: 8 bits × 32 registers (8 bits × 8 registers × 4 banks)
- Buffer RAM: 32 bytes (can be used for transfer in CSI with automatic transmit/receive function) (78K0/KF2 only)
- On-chip single-power-supply flash memory
- Self-programming (with boot swap function)
- On-chip debug function (µPD78F05xxD and 78F05xxDA only)
- On-chip power-on-clear (POC) circuit and low-voltage detector (LVI)
- On-chip watchdog timer (operable with the on-chip internal low-speed oscillation clock)
- On-chip 10-bit resolution A/D converter (AVREF = 2.3 to 5.5 V)
- On-chip multiplier/divider (16 bits × 16 bits, 32 bits/16 bits), key interrupt function, clock output/buzzer output controller, I/O ports, timer, and serial interface
- Power supply voltage
- Standard products, (A) grade products: VDD = 1.8 to 5.5 V
- (A2) grade products: VDD = 2.7 to 5.5 V
- Operating ambient temperature
- Standard products, (A) grade products: TA = –40 to +85°C
- (A2) grade products: TA = –40 to +125°C
