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.ApplicationsFitness/Health WearablesPortable and Wearable Wireless Medical DevicesAsset TrackingIndustrial Sensors and Networks
