  MAX32690

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 Low Energy (LE) radio. This device unites processing
horsepower with the connectivity required for IoT applications.
The MCU offers many features to increase reliability: full-time error detection and correction (ECC) on processor cache and
optional ECC on SRAM. The MAX32690 is qualified to operate at a temperature range of -40°C to +105°C, ideal for Industrial
environments.
Bluetooth® 5 Low Energy (LE) radio supports Mesh, LE Audio, angle of arrival (AoA), and angle of departure (AoD) for
direction finding, long-range (coded), and high-throughput modes. A dedicated RISC-V core handles timing-critical
controller tasks, freeing the programmer from BLE interrupt latency concerns.
A Trust Protection Unit (TPU) provides advanced security features, including a Modular Arithmetic Accelerator (MAA) for
fast ECDSA, an AES Engine, TRNG, SHA-256 Hash, and a Secure Boot Loader.
Internal code and data spaces can be expanded off-chip through a quad SPI execute-in-place (XIP) interface or a
Hyperbus/Xccela™ interface.
Many high-speed interfaces are supported on the device, including multiple QSPI, UART, CAN 2.0, and I2
C serial interfaces,
plus one I2
S 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 1 MHz.
