The MAX32690 microcontroller (MCU) is an advanced system-on-chip (SoC) featuring an Arm® Cortex®-M4F CPU, large flash and SRAM memories, and the latest generation Bluetooth® 5.2 Low Energy (LE) radio. This device unites processing horsepower with the connectivity required for IoT applications.

The MAX32690 is qualified to operate over the -40°C to +105°C range, which is ideal for industrial environments.This device is available in a 68-pin TQFN-EP (0.40mmpitch) and a 140-bump WLP (0.35mm pitch).

Bluetooth 5.2 Low Energy (LE) radio supports Mesh, angle of arrival (AoA), and angle of departure (AoD) for direction finding, long-range (coded), and high-throughput modes. LE Audio hardware implemented with software codec is provided separately. A RISC-V core optionally handles timing-critical controller tasks, freeing the programmer from Bluetooth LE interrupt latency concerns.

A cryptographic toolbox (CTB) provides advanced security features, including an MAA for fast Elliptic Curve Digital Signature Algorithm (ECDSA), Advanced Encryption Standard (AES) Engine, TRNG, SHA-256 hash, and secure boot loader. Internal code and SRAM space can be expanded off-chip through two quad-SPI execute-in-place (SPIXF and SPIXR) interfaces up to 512MB each.

Many high-speed interfaces are supported on the device, including multiple QSPI, UART, CAN 2.0B, and I2C serial interfaces, plus one I2S port for connecting to an audio codec. All interfaces support efficient DMA-driven transfers between peripheral and memory. A 12-input (8 external), 12-bit SAR ADC samples analog data at up to 1Msps.

Arduino Form-factor Development Platform Based on MAX32690 ARM Cortex-M4 Microcontroller

Features and Benefits

  • Allows prototyping of intelligent, secure, and connected industrial field devices
  • Arduino Mega-compatible form factor
  • Two Pmod™-compatible connectors
  • ARM Cortex-M4 Ultra Efficient Microcontroller with integrated Bluetooth 5.2 LE
  • WiFi connectivity
  • Long-range, single-pair 10BASE-T1L Ethernet interface

  • Open-source software stack

Product Detail

The AD-APARD32690-SL is a platform for prototyping intelligent, secure, and connected field devices. It has an Arduino Mega-compatible form factor and two Pmod™-compatible connectors.

The system includes the MAX32690 ARM Cortex-M4 with FPU-Based Microcontroller and Bluetooth LE 5.2. The MCU is coupled with external RAM (2 x 512 Mb) and Flash (64 Mb) memories to meet the requirements of the most demanding applications. The MAXQ1065 security coprocessor enables state of the art security features such as for root-of-trust, mutual authentication, data confidentiality and integrity, secure boot, and secure communications.

A 10 Mbps single-pair Ethernet link using the ADIN1110 10BASE-T1L MAC/PHY, enables remote data acquisition and system configuration. The 10BASE-T1L interface also supports Single-pair Power over Ethernet (SPoE) and be used for powering the system via an Arduino shield implementing the required power circuitry.

WiFi connectivity is provided via the on-board NINA-W102 multiradio wireless MCU module with internal antenna.

Power can be supplied either via the USB-C connector or via a 2-pin terminal block. The supported input voltage range is 5 V to 28 V.

The system is accompanied by an open-source software stack and associated collateral, enabling a complete experience from evaluation, and prototyping, all the way to production firmware and application development. The open-source software stack also includes drivers and example applications for a wide variety of ADCs, DACs, sensors, and other devices commonly used in industrial applications, further accelerating the development process. An external programmer such as the MAX32625PICO DAPLink, or any other similar programmer supporting the SWD interface, enables firmware programming and debug. The system’s firmware is based on Analog Devices’ open-source no-OS framework which includes all the tools required for embedded code development and debugging as well as libraries, enabling host-side connectivity for system configuration and data transfer over the UART, USB, WiFi, and 10BASE-T1L interfaces.
