Darwin Ultra-Low-Power Microcontrollers
DARWIN is the name we give to our extensive range of Arm® microcontrollers, which are designed to provide maximum performance with minimal power consumption. This range of highly integrated, secure, ultra-low-power microcontrollers provide a choice of memory size and cores, giving you the flexibility to pick the microcontroller that best suits your application. Notable features of this range of ultra-low-power microcontrollers include:
The ultra-low-power active/retention modes (SRAM maintained) of the MCUs maximize the uptime of battery-powered devices
- Smart/Autonomous Devices
With up to 3MB flash, 1MB SRAM, and a scalable memory architecture, these ultra-low-power microcontrollers are capable of storing, processing, and acting on the vast amounts of data used by these devices.
Using a modular arithmetic accelerator (MAA) with a hardware entropy source for advanced security features (AES, ECDSA, RSA, DSA, TRNG) while providing support for secure boot loading, the level of security provided by these microcontrollers is comparable to those used by financial and government institutions.
These ultra-low-power microcontrollers have a dual-core MCU option which provide ample processing power for high-performance multitasking.
Integrated BLE 5.0 allows interconnection of devices without needing to rely on a separate chip.
