LOW POWER CONSUMPTIONSNOOZE mode for more power savings In SNOOZE mode the CPU is halted while A/D conversion and data reception are enabled. By transitioning from STOP mode (clock stopped) to SNOOZE mode, it is possible to start the on-chip oscillator and operate peripheral functions while the CPU remains inactive. SNOOZE mode ■ It is not necessary to activate the CPU for data reception. ■ Using the exclusive SNOOZE mode, peripheral functions such as the ADC, UART or CSI can operate when CPU is in standby mode. ■ Power consumption is one-tenth of normal operation. SNOOZE mode: 0.5 mA, RUN mode...

BROAD SCALABILITY Extensive memory size and package options Excellent pin compatibility The extensive lineup includes more than 500 product versions, with memory sizes from 1 KB to 512 KB and package pin counts from 10 pins to 144 pins. This extensive selection provides support for a broad range of application fields, including consumer, automotive, industrial, and communications. The wide range of options means a lot to developers if there are changes made to the specifications or more ROM capacity becomes necessary than originally estimated in the middle of the development process.
