  • Power supply voltage: VDD = 1.8 to 5.5 V
  • Max. frequency: 10 MHz
  • ROM capacities: 4 KB to 16 KB flash memory
  • RAM capacities: 384 bytes to 768 bytes
  • 16-pin plastic SSOP package
  • Low power consumption (VDD = 3.0 V)
    - Internal high-speed oscillation mode: 260 µA (TYP.) (at fCPU = 1 MHz operation)
    - STOP mode: 0.7 µ A (TYP.) (at fIL = 30 kHz operation)
  • Clock
    - High-speed system clock ... Selected from the following three source
    - 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)
    - Low-speed system oscillator 30 kHz ± 10 % ... Watchdog timer, timer clock in intermittent operation
    - Subsystem clock: Clock to operate the real-time counter mainly
  • Timer
    - 16-bit timer/event counter ... Timer output, capture input: 1 channel
    - 8-bit timer H ... PWM output: 1 channel
    - 8-bit timer/event counter 5 ... PWM output, external event counter input: 1 channel
    - Watchdog timer ... Operable with low-speed internal oscillation clock: 1 channel
  • Serial interface
    - UART ... Asynchronous 2-wire serial interface: 1 channel
    - IICA ... Clock synchronous 2-wire serial interface, multimaster supported, standby can be released upon address match in slave mode: 1 channel
  • 10-bit resolution A/D conversion: 4 channels
  • Operational amplifier (products with operational amplifier only): 1 channel
  • Power-on-clear (POC) circuit
  • Low-voltage detector (LVI) (An interrupt/reset (selectable) is generated when the detection voltage is reached))
    - Detection voltage: Selectable from sixteen levels between 1.91 and 4.22 V
  • 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 +85°C
