Arm® Cortex®-M4 with FPU microcontroller and Bluetooth® LE5.
The MAX32690 microcontroller (MCU) is an advanced system-on-chip (SoC) featuring an Arm Cortex-M4F CPU, large Flash and SRAM memory, and a Bluetooth 5.2 low-energy (LE) radio. The device combines processing power with the connectivity required for IoT applications.
The Bluetooth 5.2 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 using software codecs is available separately. The RISC-V core can optionally handle timing-critical controller tasks, freeing programmers from Bluetooth LE interrupt latency issues. The Cryptographic Toolbox (CTB) provides advanced security features including MAA for fast Elliptic Curve Digital Signature Algorithm (ECDSA), Advanced Encryption Standard (AES) engine, TRNG, SHA-256 hashing, and a secure bootloader.
Internal code and SRAM space can be expanded off-chip through two quad SPI execute-in-place (SPIXF and SPIXR) interfaces up to 512 MB each. The device supports multiple high-speed interfaces, including multiple QSPI, UART, CAN 2.0B, and I 2 C serial interfaces, as well as an I 2 S port for connecting to an audio codec. All interfaces support efficient DMA-driven transfers between peripherals and memory. The 12-input (8 external), 12-bit SAR ADC samples analog data at up to 1 MSPS.
The MAX32690 operates over the -40°C to +105°C temperature range, making it ideal for industrial environments. All devices are available in 68 TQFN-EP 0.40mm pitch package and 140 bump WLP (0.35mm pitch package).
The MAX32690EVKIT evaluation kit (EV kit) provides a platform for evaluating the capabilities of the advanced SoC MAX32690 microcontroller.
