说明

The 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. On board is the latest generation Bluetooth® 5.2 Low Energy (LE) radio, supporting LE Audio, angle of arrival (AoA), and angle of departure (AoD) for direction finding, long-range (coded), and high-throughput modes.

The device offers large onboard memory with 512KB flash and 128KB SRAM, with optional error correction coding on one 32KB SRAM bank. This 32KB bank can be optionally retained in backup mode. An 8KB user OTP area is available and 8 bytes are retained, even during power-down.

Many high-speed interfaces are supported on the device including multiple QSPI, UART, and I2C serial interfaces, 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.

The device is available in an 81 CTBGA (9 x 9, 8mm x 8mm, 0.8mm pitch) package.
