M091YD2AE

Microcontrollers Overview

The Nuvoton M091YD2AE is a 32-bit microcontroller based on the Arm Cortex-M0 core, operating at 72 MHz. It features 64 KB of Flash memory and 8 KB of SRAM. The device integrates an advanced analog front-end including four operational amplifiers with 8 MHz gain-bandwidth product, four 12-bit digital-to-analog converters, and a 16-channel 12-bit SAR ADC capable of 2 MSPS sampling rate. A built-in temperature sensor supports calibration functions.

Microcontrollers Feature Summary

• Integrates four chopper-stabilized operational amplifiers with low temperature drift characteristics for precision signal conditioning
• Includes dedicated power supply pins for analog peripherals to minimize noise interference from the digital core
• Provides high-speed data conversion capabilities via a 16-channel ADC supporting up to 2 MSPS sampling rate
• Features internal temperature sensing for hardware-based drift compensation in optical or biosensing applications

Microcontrollers Applications

• Optical biosensing systems requiring raw data acquisition
• Industrial sensor interfaces demanding high-precision analog signal processing
• Smart sensor nodes utilizing integrated temperature compensation

Microcontrollers Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the 64 KB Flash variant meets firmware size requirements. Ensure power supply design accommodates separate VDD domains for the MCU core and analog peripherals as specified in the electrical characteristics section.

Microcontrollers Selection Notes

Select this model when application requirements exceed standard GPIO capabilities but do not necessitate higher-performance cores like Cortex-M4. The inclusion of multiple OPAs and DACs reduces external component count for signal conditioning circuits. Consider the 72 MHz clock speed sufficient for control loops while prioritizing analog accuracy over computational throughput.

Microcontrollers Part Context

This component belongs to the NuMicro M091 series, designed specifically for industrial sensing applications. It distinguishes itself within the Nuvoton portfolio by offering a highly integrated analog front-end on a low-power Cortex-M0 platform, bridging the gap between simple MCUs and complex application-specific integrated circuits.

Microcontrollers Replacement Considerations

M091TC2AE: Identical architecture with 32 KB Flash instead of 64 KB. Suitable if code size is limited. M091TD2AE: Alternative package option for the same 64 KB Flash specification. Verify pin compatibility if changing packages.
