ADUCM4050BCPZ Description
The ADuCM4050 microcontroller unit (MCU) is an ultra lowpower integrated microcontroller system with integrated powermanagement for processing, control, and connectivity. The MCU system is based on the ARM? Cortex?-M4F processor. TheMCU also has a collection of digital peripherals, embeddedstatic random access memory (SRAM) and embedded flashmemory, and an analog subsystem that provides clocking, reset,and power management capabilities in addition to an analogto-digital converter (ADC) subsystem. This data sheet describes the ARM Cortex-M4F core andmemory architecture used on the ADuCM4050 MCU. It doesnot provide detailed programming information about the ARMprocessor.
