MAX32690EXEBL+T

The MAX32690 microcontroller (MCU) is an advanced system-on-chip (SoC) featuring an Arm^®Cortex^®-M4F CPU, large flash and SRAM memories, and 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 68-pin TQFN-EP (0.40mm pitch), 140-bump WLP (0.35mm pitch), and 144-CTBGA (0.8mm pitch) packages.The integrated Bluetooth 5.2 Low Energy (LE) radio supports long-range (coded) and high-throughput modes. A RISC-V core optionally handles timing-critical controller tasks, freeing the programmer from Bluetooth LE interrupt latency concerns.Internal code and SRAM space can be expanded offchip through two quad-SPI execute-in-place (SPIXF and SPIXR) interfaces up to 512MB each.A cryptographic toolbox (CTB) provides a modular arithmetic accelerator (MAA), advanced encryption standard (AES) engine, TRNG, and SHA-2 engine. The device also provides extensive security features including a 128-bit unique serial number (USN), physically unclonable function (PUF), secure nonvolatile key storage, a memory decryption integrity unit (MDIU) for SPIXF and SPIXR, and the Arm memory protection unit (MPU). The optional secure communications protocol boot loader (SCPBL) provides an immutable root of trust, secure boot with flash integrity validation using ECDSA, and secure firmware update ability.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. Most interfaces support DMA-driven transfers between memory (flash or SRAM) and a peripheral. A 12-input (8 external), 12-bit SAR ADC samples analog data at up to 1Msps.
