MAX32655 Arm® Cortex®-M4 Processor
Analog Devices' MAX32655 low-power Arm Cortex-M4 processor has an FPU-based microcontroller and Bluetooth® 5.2
ADI's MAX32655 microcontroller (MCU) is an advanced system-on-chip (SoC) featuring an Arm Cortex-M4F CPU for efficient computation of complex functions and algorithms that is qualified to operate at a temperature range of -40°C to +105°C. The SoC integrates power regulation and management with a single inductor multiple-output (SIMO) buck regulator system. The latest generation Bluetooth 5.2 Low Energy (LE) radio is
on board, supporting long-range (coded) and high-throughput modes and medical body area network (MBAN). The device offers large onboard memory with 512 KB Flash and 128 KB SRAM, with optional error correction coding (ECC) on one 32 KB SRAM bank. This 32 KB bank can be optionally retained in BACKUP mode. An 8 KB user OTP area is available.

The MAX32655 supports multiple high-speed peripherals, such as I2C, 50 MHz SPI, and UART, plus one I2S port for connecting to an audio codec. An eight-input, 10-bit ADC is available to monitor analog input from external analog sources. In addition, a low-power UART (LPUART) is available for operation in the lowest power sleep modes to facilitate wake-up activity without any data loss. A total of six timers with I/O capability are provided, including two low-power timers to enable pulse counting, capture/compare, and pulse-width modulation (PWM) generation, even in the lowest power sleep modes.
The MAX32655 is available in an 81 CTBGA package (8 mm x 8 mm, 0.8 mm pitch).
