A New Choice for Motor Control! In-Depth Analysis of PY32MD320 Chip: Integrated Pre-Driver + Low Power Consumption, with Costs Reduced by 30%?


A Must-Read for Engineers: This Chip "Welds" Three-Phase Drive into the MCU!



For Those Developing Water Pumps, Power Tools, or RC Models: Are You Still Troubled by the Tedious "MCU + Driver Board" Design?


Puya Semiconductor’s newly launched PY32MD320 series chips directly integrate the three-phase half-bridge driver into a 32-bit MCU—slashing the size by half while reducing costs. Today, we’ll break down the hard-hitting technical insights hidden in this datasheet!


PY32MD320


Core Parameter Highlight: Big Power in a Small Package


As an MCU Specifically Designed for Motor Control, the PY32MD320 Boasts an "Configuration List" Full of Highlights:

Performance Core: Equipped with a 32-bit ARM® Cortex®-M0+ core and a maximum clock frequency of 48 MHz, it easily handles BLDC/PMSM algorithm operations.

Memory Configuration: Features 64KB Flash and 8KB SRAM, meeting the storage requirements of complex control programs.

Extreme Environment Adaptability: Operates within a wide temperature range of -40℃~105℃ and supports a wide input voltage of 2.0~5.5V, ensuring stable performance in industrial scenarios.

Package Advantage: Adopts an ultra-compact QFN32 (4*4mm) package with 8 pins on each side, saving space for PCB layout.


The Biggest Surprise: Built-in Three-Phase Pre-Driver, Eliminating Half a Driver Board


This Is the Most Revolutionary Design of the PY32MD320 — Integrating a Multi-Function Three-Phase NN-Type Half-Bridge Gate Driver, Eliminating the Need for External Driver Chips Altogether:


✅ 40V floating withstand voltage, 5.5~18V driving voltage, compatible with mainstream motors

✅ ±0.8A output current, no additional current expansion circuit required

✅ Built-in bootstrap diode + 5V/50mA LDO, reducing peripheral components by half

✅ 4 channels of adjustable voltage-divider comparators + 1 channel of PGA, enabling more accurate current sampling


Low-Power Black Technology: Standby Current as Low as 4.5μA

Worried About Battery Life for Industrial Equipment? Its Power Consumption Control Is Exceptional:



Equipped with an LPTIM (Low-Power Timer), it can be quickly woken up from Stop mode—perfect for battery-powered devices.


How Low Is the Development Threshold? Even Beginners Can Get Started Quickly


Puya Provides a "Complete Suite" of Development Support for It:

Full SDK (Software Development Kit): Includes dedicated motor control libraries (FOC / square wave drive examples)

Hardware Tools: StartKit development board + on-board debugger, plug-and-play

Documentation Support: Comprehensive coverage of reference designs, application notes, and video tutorials

Tip: Supports SWD (Serial Wire Debug) single-wire debugging—no need to disassemble the board to troubleshoot, doubling debugging efficiency!


These Scenarios Are a No-Brainer to Adopt It!

✅ Household / industrial water pumps (constant-pressure water supply, hot water circulation)

✅ Power tools (electric drills, sanders)

✅ Model aircraft / drones (brushless motor drive)

✅ Small household appliances (fans, robotic vacuums)
