CONFIDENTIAL

•

Clock Supervisor

•

Anomaly supervisory feature (by damaged quartz, etc.) of external main oscillation (4MHz)

•

When anomaly is detected, clock is switched to CR.

•

Up/ down counter: 2 channels

8/16-bit Up/ down counter

•

Base timer: 2 channels

•

16-bit timer

•

Any of four PWM/PPG/PWC/reload timer functions can be selected and used.

•

As for the functions of PWC and reload timer, 2 channels of cascade mode can be used as 32-bit

timer..

•

CRC generation

•

Watchdog timer

•

Hardware watchdog

•

Software watchdog

•

NMI

•

Interrupt controller

•

Interrupt request batch read

Multiple interrupts from peripherals can be read by a series of registers.

•

I/O relocation

Change of pin position of peripheral functions

•

Low-power consumption mode

•

Sleep/Stop/Watch

•

Stop (Power shut-off)/Watch (Power shut-off)

•

Power-on reset

•

Low-voltage detection reset (external low-voltage detection)

•

Low-voltage detection reset (internal low-voltage detection)

•

Device package: LQFP-144

•

CMOS 90 nm technology

•

Power supplies

•

Single 5V power supply

•

The voltage step-down circuit brings the 5.0V down to generate 1.2V internally

•

I/O 5.0V
