MAX32680

Ultra-Low-Power Arm Cortex-M4F with

Precision Analog Front-End

and Bluetooth LE 5.2

General Description

Benefits and Features

The MAX32680 microcontroller (MCU) is an advanced

● Ultra-Low-Power Wireless Microcontroller

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 +85°C. The SoC integrates power reg-

ulation and management with a single-inductor multiple-

output (SIMO) buck regulator system. Onboard is the lat-

• Internal 100MHz Oscillator

• 512KB Flash and 128KB SRAM

• Optional ECC on One 32KB SRAM Bank

● Bluetooth 5.2 LE Radio

• Dedicated, Ultra-Low-Power, 32-Bit RISC-V

Coprocessor to Offload Timing-Critical Bluetooth

Processing

• Fully Open-Source Bluetooth 5.2 Stack Available

• Supports AoA, AoD, LE Audio, and Mesh

• High-Throughput (2Mbps) Mode

est generation Bluetooth 5.2 Low Energy (LE) radio, sup-

porting LE Audio, angle of arrival (AoA), and angle of

departure (AoD) for direction finding, long-range (coded)

modes, and high-throughput modes.

The device offers large onboard memory with 512KB flash

and 128KB SRAM, with optional error correction coding

(ECC) on one 32KB SRAM bank. This 32KB bank can be

optionally retained in BACKUP mode. An 8KB user one-

time programmable (OTP) area is available, and 8 bytes

are retained, even during power-down.

• Long-Range (125kbps and 500kbps) Modes

• Rx Sensitivity: -97.5dBm; Tx Power: +4.5dBm

• Single-Ended Antenna Connection (50Ω)

● Smart Integration Reduces BOM, Cost, and PCB Size

• Two 16-Bit to 24-Bit Δ-Σ ADCs

• 12 Channels, Assignable to Either ADC

• Flexible Resolution and Sample Rates

• 24-Bits at 0.4ksps, 16-Bits at 4ksps

• Four External Input, 10-Bit Δ-Σ ADC 7.8ksps

• 12-Bit DAC

An analog front-end (AFE) provides two 12-channel delta-

sigma (Δ-Σ) analog-to-digital converters (ADC) with fea-

tures and specifications optimized for precision sensor

measurement. Each Δ-Σ ADC can digitize external analog

signals as well as system temperature. An optional pro-

grammable gain amplifier (PGA) with gains of 1x to 128x

precedes each ADC. ADC outputs can be optionally con-

verted on the fly from integer to single-precision floating-

point format. A 12-bit digital-to-analog converter (DAC) is

also included. The device also provides robust security

features such as an advanced encryption standard (AES)

engine, true random number generator (TRNG), and se-

cure boot.

• On-Die Temperature Sensor

• Digital Peripherals: Two SPI, Two I C, up to Four

UART, and up to 36 GPIOs

• Timers: Six 32-Bit Timers, Two Watchdog Timers,

Two Pulse Trains, 1-Wire Master

● Power Management Maximizes Battery Life

• 2.0V to 3.6V Supply Voltage Range

• Integrated SIMO Power Regulator

• Dynamic Voltage Scaling (DVS)

The device is available in an 88L LGA (10mm x 10mm,

0.4mm pitch) package.

• 23.8μA/MHz ACTIVE Mode Current at 3.0V

Coremark

• 4.4μA at 3.0V Retention Current for 32KB SRAM

• Selectable SRAM Retention in Low-Power Modes

Applications

● Industrial Pressure, Temperature, Level, and Flow

● Robust Security and Reliability

• TRNG

Sensors/Transmitters

● Medical Pressure and Temperature Sensors

• Secure Nonvolatile Key Storage and AES-128/192/

256

• Secure Boot to Protect IP/Firmware

• Wide, -40°C to +85°C Operating Temperature
