STM32G4A1REI6 - 170MHz 512KB Cortex-M4 MCU | STMicroelectronics
MPN: STM32G4A1REI6 ✓ AktifSTM32G4A1REI6 Genel Bakış
A microcontroller is a semiconductor device that integrates a processor core, nonvolatile program memory, data memory, peripherals, and communication interfaces on one integrated circuit. The STM32G4 family belongs to the Arm Cortex-M microcontroller hierarchy: STM32G4 device -> 32-bit microcontroller -> embedded processor -> embedded semiconductor. This integration lets a compact control board combine real-time control, data acquisition, communications, and safety monitoring without separate interface devices.
The supplied data identifies the processor as Arm Cortex-M4F, the core width as 32 bits, and the maximum frequency as 170 MHz. Its 512 KB Flash store provides 512K x 8 organization for firmware. The listed connectivity is unusually broad for a compact controller, covering CANbus, I2C, SPI, UART/USART, USB, SAI, LINbus, IrDA, and IRTIM. Listed system peripherals include brown-out detection/reset, DMA, I2S, POR, PWM, and WDT.
The STM32G4A1REI6 is identified as part of STMicroelectronics' mainstream STM32G4 line and is supplied in a compact 64-UFBGA package. Its combination of a 170 MHz core, 512 KB Flash, and extensive serial interfaces supports responsive control loops and connected embedded products. Exact RAM capacity, voltage range, pin assignments, ADC specifications, timer channels, and electrical limits are not supplied in the verified excerpts and must be confirmed from the complete STMicroelectronics documentation before design release.
Typical applications include industrial automation controllers, CAN network nodes, motor and power-system controllers, sensor hubs, communication gateways, USB-enabled embedded equipment, and compact control boards. The STM32G4A1REI6 is particularly appropriate where several communication standards and a high-performance 32-bit core must coexist in a small board area.
Design work should begin with the exact 64-UFBGA land pattern and pin multiplexing table. Keep high-speed and sensitive routes controlled, provide clean power and decoupling according to the full datasheet, and verify boot, clock, reset, and peripheral assignments in the selected STM32CubeMX configuration. Do not infer the complete pinout or electrical limits from distributor snippets alone.
This page consolidates verified distributor and manufacturer information, package and interface facts, application guidance, sourcing references, and design cautions. It adds engineering context while clearly separating confirmed values from details that still require the complete manufacturer datasheet and product documentation.

Tipik Uygulamalar
STM32G4A1REI6 için uygundur 6 uygulamas: Industrial Automation Controller, CAN Network Node, Motor and Power-System Control, USB-Enabled Embedded Equipment, Sensor Hub and Data Acquisition, Communication Gateway.
Industrial Automation Controller
The STM32G4A1REI6 fits compact industrial control equipment that needs a 170 MHz 32-bit Cortex-M4F core while coordinating multiple communication links. Its verified connectivity includes CANbus, UART/USART, I2C, SPI, and USB, enabling the controller to combine supervisory logic, sensor acquisition, actuator commands, and a service interface. The 512 KB Flash store supports a substantial embedded firmware image, while DMA, PWM, and watchdog functions help distribute real-time work. The 64-UFBGA 5 x 5 mm package also supports compact board designs. Before layout, verify exact power balls, clock pins, debug access, and alternate-function mappings in the official STMicroelectronics documentation.
Önerilen
CAN Network Node
The STM32G4A1REI6 is suitable for a CAN-connected industrial node because the verified feature list explicitly includes CANbus, alongside I2C, SPI, UART/USART, and USB. A 170 MHz Cortex-M4F processor can execute protocol handling and local control logic, while the 512 KB Flash capacity provides room for application firmware and communication stacks. DMA is listed as a peripheral and can help transfer data efficiently when the complete device configuration confirms compatible DMA resources. Keep the PCB layout and termination strategy consistent with the selected transceiver, and verify pin multiplexing, transceiver supply requirements, and CAN timing against the complete official documentation.
Önerilen
Motor and Power-System Control
The STM32G4A1REI6 is a strong candidate for compact motor-control and power-system logic because the verified data identifies a 170 MHz Arm Cortex-M4F core, PWM, DMA, watchdog, and multiple serial interfaces. PWM supports periodic actuator or conversion functions, while DMA can reduce processor involvement in data movement when the final pin and channel assignments are confirmed. The 512 KB Flash store is useful for control algorithms, diagnostics, and communication firmware. The device should not be treated as a power-stage replacement; external drivers, protection, sensing, and magnetics remain necessary. Confirm timer resolution, complementary outputs, ADC characteristics, voltage limits, and thermal data before selecting the final power-control architecture.
Önerilen
USB-Enabled Embedded Equipment
The STM32G4A1REI6 can support USB-connected embedded equipment because USB is explicitly listed among its connectivity options, while SPI, UART/USART, I2C, and I2S provide additional local interfaces. The 170 MHz 32-bit Cortex-M4F core is suitable for coordinating user-interface functions, data buffering, configuration, and peripheral control. Its 512 KB Flash capacity supports a meaningful embedded application image, and DMA may assist with data movement. Design the USB interface according to the official electrical and layout requirements, including the correct transceiver or USB PHY arrangement, power management, routing, and connector protection. The supplied search data does not confirm USB speed, endpoint count, or PHY implementation, so those details must be verified before final schematic sign-off.
Önerilen
Sensor Hub and Data Acquisition
The STM32G4A1REI6 is well matched to a sensor hub that must aggregate several embedded peripherals and communicate with a host. I2C and SPI are listed for short-range sensor connections, UART/USART and USB provide broader host or service connectivity, and DMA can assist with transferring sampled data. The 170 MHz Cortex-M4F core leaves performance margin for filtering, calibration, diagnostics, and protocol processing, while 512 KB Flash provides firmware capacity for a larger application. The actual ADC resolution, sampling rate, timer channels, RAM, and analog supply requirements are not included in the verified excerpts. Confirm those specifications and the exact 64-UFBGA ball map before designing the analog front end or sensor bus.
Önerilen
Communication Gateway
The STM32G4A1REI6 can serve as a compact protocol gateway between embedded equipment and a host interface. Its verified list includes CANbus, LINbus, I2C, SPI, UART/USART, USB, IrDA, and IRTIM, enabling a single controller to bridge several physical or logical domains. The 170 MHz Cortex-M4F core and 512 KB Flash support protocol state machines, buffering, diagnostics, and configuration storage. The broad interface list does not by itself guarantee that every protocol is simultaneously usable, because package pins, alternate functions, peripheral instances, and DMA assignments are finite. Build the peripheral matrix from the official datasheet and STM32CubeMX device data, then validate timing and pin conflicts in hardware.

Tasarım Notları
Begin the PCB layout with the official 64-UFBGA ball map and land pattern rather than a generic BGA footprint. Confirm every power, ground, VCAP, reset, boot, clock, debug, and peripheral signal ball before routing. Keep decoupling and power-distribution geometry consistent with the manufacturer recommendations, and verify the package-specific solder mask, paste, and assembly process window.
Do not treat a same-package STM32G4 comparison part as a drop-in replacement based only on the 64-UFBGA label. The verified comparison data does not establish identical pin multiplexing, memory, clock, peripheral, electrical, or firmware compatibility. Create a pin-by-pin and function-by-function substitution report using the complete STMicroelectronics documentation before changing a released BOM.
For USB, high-speed clocks, or other timing-sensitive interfaces, preserve the manufacturer's recommended topology and controlled-impedance routing rules. The verified excerpts confirm USB connectivity but do not specify USB speed, PHY arrangement, or pin locations, so those details must be obtained from the full datasheet and reference design. Validate signal integrity with the final stack-up and enclosure or connector configuration.
Plan the power tree around the exact STM32G4A1REI6 voltage and current limits from the official documentation; those values are not present in the supplied search data. Provide local decoupling at the device pins, separate sensitive analog or communication supplies where the reference design requires it, and include measurement points for startup, brown-out behavior, and load transients. Validate thermal performance using the actual PCB copper and enclosure.
Uyumluluk Bilgisi
The supplied verified data does not state compliance status for RoHS, REACH, AEC-Q100, lead-free construction, halogen-free construction, or conflict minerals. Confirm these details from the official STMicroelectronics product documentation or current declaration files.
