Microcontroller

GENERAL DESCRIPTION

The
ADuCM4050
is an ultra low power, integrated, mixed
signal microcontroller units (MCUs) used for processing,
control, and connectivity. The MCU system is based on an
ARM® Cortex-M4F processor, which is a 32-bit reduced
instruction set computer (RISC) processor and runs up to
52 MHz. The device has 512 kB of embedded flash memory
with error correction code (ECC) and 128 kB of system RAM
with parity.
The
ADuCM4050
also features a collection of digital peripherals,
and an analog subsystem that provides clocking, reset, and power
management capabilities in addition to an analog-to-digital
converter (ADC) subsystem.
Refer to the
ADuCM4050
