Description
Low-pin-count (78K0S/Kx1+) microcontrollers are low-end Microcontrollers. The flash only products include OSC and comprehensive development tools.
- 78K0S CPU core
- Minimum instruction execution time: 0.2µs (with 10 MHz@4.0 to 5.5 V operation)
- Clock
- High-speed system clock. Selected from the following three sources
- Ceramic/crystal resonator: 2 to 10MHz (Standard product, (A) grade product)2 to 8 MHz ((A2) grade product)
- External clock: 2 to 10 MHz (Standard product, (A) grade product)2 to 8 MHz ((A2) grade product)
- High-speed internal oscillator: 8 MHz±3% (-10 to +70°C),8 MHz±5% (Standard product, (A) grade product:-40 to +85°C, (A2)grade product:-40 to +125°C)
- Low-speed internal oscillator 240 kHz (TYP.). Watchdog timer, timer clock in intermittent operation
- I/O ports: 14 (CMOS I/O: 13, CMOS input: 1)
- Timer: 3 channels
- 16-bit timer/event counter: 1 channel. Timer output×1, capture input×2
- 8-bit timer: 1 channel. PWM output×1
- Watchdog timer: 1 channel. Operable with low-speed internal oscillation clock
- On-chip power-on-clear (POC) circuit (A reset is automatically generated when the voltage drops to 2.1 V (TYP.)or below)
- 10-bit resolution A/D converter ( µPD78F921x only): 4 channels
- On-chip low voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltage is reached)
- Detection voltage: Selectable from ten levels between 2.35 and 4.3 V
- Single-power-supply flash memory
- Flash self programming enabled
- Software protection function: Protected from outside party copying (no flash reading command)
- Time required for writing by dedicated flash memory programmer: Approximately 3 seconds (4 KB)
- Flash programming on mass production lines supported
- Safety function
- Watchdog timer operated by clock independent from CPU
- A hang-up can be detected even if the system clock stops
- Supply voltage drop detectable by LVI
- Appropriate processing can be executed before the supply voltage drops below the operation voltage
- Equipped with option byte function
- Important system operation settings set in hardware
- Assembler and C language supported
- Enhanced development environment
- Support for full-function emulator (IECUBE), simplified emulator (MINICUBE2), and simulator
- Supply voltage: VDD= 2.0 to 5.5 V
- Use these products in the following voltage range because the detection voltage (VPOC) of the POC circuit is the supply voltage range.
- Standard product, (A) grade product: 2.2 to 5.5 V, (A2) grade product: 2.26 to 5.5 V
- Operating temperature range:
- Standard product, (A) grade product: TA=-40 to +85°C
- (A2) grade product: TA=-40 to +125°C
