  • Clock
  • High-speed system clock (Selected from the following three sources)
    • Ceramic/crystal resonator: 2 to 10 MHz (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)

    • Low-speed internal oscillator 240 kHz (TYP.) Watchdog timer, timer clock in intermittent operation

 

  • I/O ports:
    • 8 : 10-pin products
    • 14 (CMOS I/O: 13, CMOS input: 1) : 16-pin products
    • 17 (CMOS I/O: 15, CMOS input: 1, CMOS output: 1) : 20-pin products
    • 26 (CMOS I/O: 24, CMOS input: 1, CMOS output: 1) : 30-pin products

 

  • Timer: 3/4 channels
    • 16-bit timer/event counter: 1 channel Timer output x 1, capture input x 2
    • 8-bit timer: 2 channels PWM output x 1
    • Watchdog timer: 1 channel Operable with low-speed internal oscillation clock

 

  • Serial interface: UART (LIN (Local Interconnect Network) bus supported) 1 channel
  • 10-bit resolution A/D converter: 0/4 channels
  • On-chip power-on-clear (POC) circuit (A reset is automatically generated when the voltage drops to 2.1 V (TYP.) or below)
  • On-chip low voltage detector (LVI) circuit (An interrupt/reset (selectable) is generated when the detection voltageis reached)

* 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), on-chip debug emulator (MINICUBE2), and simulator

 

  • Operating temperature range:
    • Standard product, (A) grade product: TA = -40 to +85°C
    • (A2) grade product: TA = -40 to +125°C
