MAX32666 - Cortex-M4 Microcontroller

Download the MAX32666 datasheet PDF. This datasheet also covers the MAX32665 variant, as both devices belong to the same cortex-m4 microcontroller family and are provided as variant models within a single manufacturer datasheet.

General Description

DARWIN is a new breed of low-power microcontrollers built to thrive in the rapidly evolving Internet of Things (IoT).

They are smart, with the biggest memories in their class and a massively scalable memory architecture.

They run forever, thanks to wearable-grade power technology.

Key Features

  • High-Efficiency Microcontroller and Audio DSP for Wearable and Hearable Devices.
  • Arm Cortex-M4 with FPU Up to 96MHz.
  • Optional Second Arm Cortex-M4 with FPU Optimized for Data Processing.
  • Low-Power 7.3728MHz System Clock Option.
  • 1MB Flash, Organized into Dual Banks 2 x 512KB.
  • 560KB (448KB ECC) SRAM; 3 x 16KB Cache.
  • Optional Error Correction Code (ECC-SEC-DED) for Cache, SRAM, and Internal Flash.
  • Bluetooth 5 Low Energy Radio.
