This device provides the following benefits:

●

Ultralow power proprietary 130 nm technology:

Speed and power consumption independent of MCU power supply, Ultralow leakage

●

Ultralow power design (clock gating, low-power Flash with power-off capability):

Reduced overall Run and Wait mode current consumption by turning off clocks of

unused peripherals or Flash

●

Sub 1 µA hardware RTC and AWU system unit:

Ultralow power modes for applications requesting regular wake up

●

Range of Low power modes (up to 4):

Suitable for many applications from complete switch off to continuous monitoring at

ultralow frequency

●

Advanced and flexible clock system (multiple internal and external clock sources):

Switch and adjust frequency and clock sources on the fly depending on application

needs

●

Direct memory access on board (4-channel DMA):

Autonomy for peripherals, independent from core; can switch off Flash memory and

CPU (large current consumption contributors) while keeping peripherals active

●

Ultralow power and ultrasafe reset system POR/PDR; additional optional activation

BOR:

Integrated safety and security for application

●

Ultrafast wakeup from lowest Low power mode (4 µs):

Fast switching from Static and Dynamic power modes

●

Analog functional down to 1.8 V, programming down to 1.65 V:
