Description
The extensive 78K series lineup provides the ideal product for almost any application. For a compact, low-power MCU, choose one of the products in the 8-bit 78K0 and 78K0S series, and for a controller that offers the performance of a 32-bit MCU but consumes the power of an 8-bit one, look no further than the 16-bit 78K0R.
- Operating voltage: VDD = 2.7 to 5.5 V
- Max. frequency: 20 MHz
- ROM capacities: 4 KB to 16 KB flash memory
- RAM capacities: 384 bytes to 768 bytes
- 78K0 CPU core
- Clock
- High-speed system clock. Selected from the following four sources
- Ceramic/crystal oscillator: 1 to 10 MHz
- External clock: 1 to 10 MHz
- Internal high-speed oscillator: 4 MHz ± 2 % (-20 to +70°C), or 8 MHz ± 5 %(-40 to +85°C)
- Clock for 16-bit timers X0 and X1: 40 MHz (TYP.) (when using PLL)
- Internal low-speed oscillator 30 kHz (TYP.). Watchdog timer, timer clock in intermittent operation When using a 4 MHz clock, operation at 20 MHz is possible by using PLL
- I/O ports: 12 to 16 (CMOS I/O: 9 to 13, CMOS input: 3)
- Timer
- 16-bit timer X : PWM output (40 MHz (MAX.) clock operation), operation in conjunction with an external signal, synchronous output of up to four channels, A/D conversion trigger generation: 2 channels
- 16-bit timer/event counter : PPG output, capture input, external event counter input: 1 channel
- 8-bit timer H1 : PWM output, operable with low-speed internal oscillation clock: 1 channel
- 8-bit timer/event counter 51 : External event counter input: 1 channel
- Watchdog timer : Operable with low-speed internal oscillation clock: 1 channel
- Serial interface
- UART6 : Asynchronous 2-wire serial interface:0/ 1 channel
- DALI : 2-wire serial interface for lighting control (slave): 0/1 channel
- IICA : Clock synchronous 2-wire serial interface, multimaster supported standby can be released upon address match in slave mode: 0/1 channel
- CSI11 : Clock synchronous 3-wire serial interface, operable as SPI in slave mode: 0/1 channel
- Multiplier (8 bits x 8 bits = 16 bits, 16 bits x 16 bits = 32 bits, 1-clock operation)
- 10-bit resolution A/D conversion: 5/6/9 channels
- Operational amplifier (Products with operational amplifier only): 1 channel
- Comparator: 3 channels
- Power-on-clear (POC) circuit
- Low-voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltage is reached)) – Detection voltage: Selectable from ten levels between 2.84 and 4.22 V
- 1.91 V is used only when the power is turned on when the LVI default start is set
- Single-power-supply flash memory
- Flash self programming enabled
- Software protection function: Protected from outside party copying (no Flash reading command)
- 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
- On-chip debug function. Available to control for the target device, and to reference memory
- Operating ambient temperature: TA = -40 to +105°C
