he Core Advantages of the PY32F030 Series: Every Aspect Tailored for Efficient Operation, from the "Heart" to the "Memory"

Powerful Core

Equipped with a 32-bit ARM® Cortex®-M0+ core, it supports a maximum operating frequency of 48MHz, balancing computing speed and energy efficiency. Compared with traditional 8-bit/16-bit MCUs, it offers higher code density and can easily handle complex control logic.

Flexible Memory

It integrates a maximum of 64Kbytes of Flash memory and 8Kbytes of SRAM, which meets the program storage and data buffering needs of most embedded applications. Meanwhile, it supports Flash read-write protection to ensure program security.

Multi-Source Clock

It provides a rich selection of clock sources: internal 4/8/16/22.12/24MHz HSI oscillators, 32.768KHz LSI oscillators, external 4~32MHz HSE crystal oscillators, and 32.768KHz LSE crystal oscillators. It also supports PLL frequency multiplication (with HSI or HSE as the source), offering maximum flexibility in clock configuration to adapt to different precision and power consumption requirements.

A High-Quality MCU Relies on Rich and Practical Peripheral Support. The PY32F030 Series Excels as an "All-Rounder" in This Aspect, Significantly Reducing the Cost of External Components and Simplifying Circuit Design:

General Purpose Input/Output (GPIO)

It features up to 30 I/O pins, all of which can be configured as external interrupts, with a drive current of 8mA. Furthermore, 4 GPIOs support ultra-strong sink current, configurable via software to 80mA/60mA/40mA/20mA, enabling easy driving of peripherals such as LEDs and relays.

Accurate Analog and Control Functions

1 x 12-bit ADC: Supports up to 10 external input channels, with an input voltage range of 0~VCC, meeting the requirements for collecting analog signals such as temperature and voltage.

2 x Comparators: Can be used for analog signal triggering, low-power wake-up, and can also cooperate with timers to achieve current control.

Rich Timers

It includes 1 x 16-bit advanced control timer (TIM1), 4 x general-purpose 16-bit timers, 1 x low-power timer (LPTIM, supporting wake-up from Stop mode), as well as an Independent Watchdog (IWDT) and a Window Watchdog (WWDT), balancing precise timing and system stability.

Efficient Communication Interfaces

Equipped with 2 x SPI, 2 x USART (supporting automatic baud rate detection), and 1 x I2C (supporting Standard/Fast modes), it covers mainstream serial communication needs and enables easy connection to peripherals such as sensors, displays, and wireless modules.

Other Practical Functions

3-channel DMA Controller: Reduces CPU load and improves data transmission efficiency.

Hardware CRC-32 Module: Enables more efficient data verification.

Unique UID: Facilitates device identification.

Serial Wire Debug (SWD): Simplifies the debugging process.

Every one of these functions directly addresses pain points in development.

Embedded devices often face challenges such as limited power supply and variable environments, and the PY32F030 series performs exceptionally well in these two aspects:

Wide Voltage Range & Low Power Consumption

It has an operating voltage range of 1.7V~5.5V, compatible with multiple power supply methods including lithium batteries, dry batteries, and regulated power supplies. It supports two low-power modes: Sleep and Stop. In Stop mode, the contents of SRAM and registers are retained, and only microampere-level current is required—making it particularly suitable for battery-powered handheld devices.

Stability & Reliability

With an operating temperature range of -40℃~85℃, it can adapt to harsh environments such as industrial sites and outdoor equipment. It integrates built-in Power-On/Power-Down Reset (POR/PDR), Brown-Out Reset (BOR), and Programmable Voltage Detection (PVD), providing comprehensive protection for the system to operate stably under voltage fluctuations and abnormal conditions.

To meet the PCB layout and space requirements of different products, the PY32F030 series offers 5 mainstream package types: LQFP32, QFN32, TSSOP20, QFN20, and SSOP24. Ranging from 32-pin to 20-pin, and covering surface-mount to narrow-body packages, it enables developers to find suitable models whether for complex industrial control boards or miniaturized consumer electronic devices.

Meanwhile, different models within the series feature segmented configurations in parameters such as Flash (16K~64K), SRAM (2K~8K), and the number of GPIOs (e.g., PY32F030K18T, PY32F030F18P). This allows developers to select models precisely based on project needs, avoiding performance redundancy and controlling costs.

Leveraging the aforementioned features, the PY32F030 series boasts an extremely wide range of application scenarios:

Industrial Control

Sensor data acquisition, motor drive, PLC modules

Consumer Electronics

Handheld devices (e.g., Bluetooth speakers, smart remote controls), PC peripherals (keyboards, mice), gaming devices

Smart Home

Smart switches, temperature and humidity monitors, control boards for small home appliances

Other Scenarios

GPS positioning modules, portable medical devices, IoT terminal nodes
