Cortex-M0 based microcontrollers with industry-leading power and efficiency

Built around the new Cortex-M0 architecture, the smallest, lowest power, and most energy-efficient ARM core ever developed, these MCUs are ideally equipped for use in many traditional 8/16-bit applications.

Key features

► ARM Cortex-M0 processor

- 50 MHz operation

- Nested Vectored Interrupt Controller for fast deterministic interrupts

- Wakeup Interrupt Controller allows automatic wake from a priority interrupt

- Three reduced-power modes: Sleep, Deep-sleep, and Deep power-down

► Memories

- Up to 128 KB Flash memory

- Up to 16 KB SRAM

► Serial peripherals

- UART with fractional baud rate generation, internal FIFO, and RS-485 support

- Up to 2 SPI controllers with FIFO and multi-protocol capabilities

- I2C-bus interface supporting full I2C-bus specification and Fast mode plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode

► Analogperipheral

- 10-bit Analog-to-Digital Converter with eight channels and conversion rates up to 400 K samples per second

► Other:

- Up to 42 general-purpose I/O (GPIO) pins with configurable pull-up/down resistors and a new, configurable open-drain operating mode

- Four general-purpose counter/timers, with a total of four capture inputs and 13 match outputs

- Programmable Watchdog Timer (WDT) with lock-out feature

- System tick timer

- Each peripheral has its own clock divider for power savings
