MAX32600-P85B+W

Application Specific Microcontrollers Overview

The MAX32600-P85B+W is a wellness measurement microcontroller based on the ARM Cortex-M3 CPU, operating at up to 24MHz. It integrates 256KB of flash memory, 32KB of SRAM, and a 2KB instruction cache. The device features an integrated analog front-end with a 16-bit ADC supporting up to 500ksps conversion rates and programmable gain amplifiers. Digital supply voltage (VDD) ranges from 1.8V to 3.6V, while the analog domain (VDDA3) operates between 2.3V and 3.6V. The P85 suffix denotes the 192-ball, 12mm x 12mm CTBGA package option.

Application Specific Microcontrollers Feature Summary

• Integrated Analog Front-End: Includes a 16-bit ADC with PGA, two 12-bit DACs, four operational amplifiers, and LED drivers for precision biosensing.
• Trust Protection Unit: Provides hardware security via AES engine, µMAA for ECDSA/RSA, and fast-erase SRAM for secure key storage.
• Low Power Consumption: Achieves 175µA/MHz active power and 1.25µA current consumption in LP0 mode with RTC enabled.
• Flexible Connectivity: Supports USB Full Speed, I2C, UART, SPI, and JTAG interfaces alongside 64 GPIOs.

Application Specific Microcontrollers Applications

• Wearable Medical Devices
• Pulse Oximetry Measurement
• Galvanic Skin Response Measurement
• Blood Glucose Metering

Application Specific Microcontrollers Procurement Notes

Verify the P85 ordering suffix corresponds to the 192-ball CTBGA package when sourcing. Confirm the +W designation indicates lead-free and RoHS compliance status as per manufacturer specifications. Ensure compatibility with the required 12mm x 12mm footprint during PCB layout planning.

Application Specific Microcontrollers Selection Notes

Select this model if a 192-ball BGA package is required for higher pin count applications compared to the 120-ball or 108-bump variants. The integrated AFE reduces external discrete component count for biosignal acquisition. Verify that the system design supports the 2.3V minimum VDDA3 requirement for optimal analog performance.

Application Specific Microcontrollers Part Context

This component belongs to the MAX32600 family of wellness measurement microcontrollers. The base part number defines the core MCU and AFE capabilities, while the suffix identifies specific package configurations. Other variants include the J85 (120-ball CTBGA) and L85 (108-bump WLP) packages.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same package are limited to other MAX32600 variants with different suffixes (e.g., J85, L85) which share identical electrical characteristics but differ in physical footprint. Cross-package replacements require schematic and PCB redesign due to pinout differences.
