• 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)
- High-speed internal oscillator: 8 MHz ±3% (−10 to +80°C),
8 MHz ±5% (Standard product, (A) grade product: −40 to +85°C,
(A2) grade product: −40 to +125°C)

• I/O ports: 26 (CMOS I/O: 24, CMOS input: 1, CMOS output: 1)

• Timer: 4 channels

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

• Serial interface: UART (LIN (Local Interconnect Network) bus supported) 1 channel

• On-chip multiplier: 8 bits × 8 bits = 16 bits

• 10-bit resolution A/D converter: 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 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
