STM32F427IGT6

Microcontrollers Overview

The STM32F427IGT6 is a high-performance microcontroller based on the Arm Cortex-M4 core with DSP and FPU, operating at up to 180 MHz. It features 1 Mbyte of Flash memory, 256 Kbytes of SRAM, and an ART Accelerator for zero-wait-state execution. The device includes a flexible external memory controller supporting SDRAM, LCD-TFT controller, Chrom-ART Accelerator, three 12-bit ADCs, two DACs, multiple timers, and extensive communication interfaces. It is housed in a 176-pin LQFP package.

Microcontrollers Feature Summary

• Integrated Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory
• Hardware-accelerated graphics processing via Chrom-ART Accelerator and LCD-TFT controller
• Flexible external memory controller supporting SDRAM, PSRAM, NOR/NAND flash, and CompactFlash
• Comprehensive peripheral set including three 12-bit ADCs, two 12-bit DACs, and multiple advanced timers

Microcontrollers Applications

• Industrial applications requiring motor control and precise timing
• Medical devices utilizing high-resolution analog-to-digital conversion
• Consumer electronics featuring graphical user interfaces
• Infotainment systems with display and connectivity requirements

Microcontrollers Procurement Notes

Verify the specific suffix 'IT6' corresponds to the industrial temperature range (-40°C to +85°C) and the 176-pin LQFP package configuration. Confirm that the 1 Mbyte Flash variant matches the design requirements, as other variants in the family may offer different memory capacities. Ensure compatibility with the intended power supply voltage range of 1.8V to 3.6V.

Microcontrollers Selection Notes

Select this component when a balance of moderate Flash capacity and high-speed external memory interface is required. The presence of the Chrom-ART Accelerator makes it suitable for applications needing efficient graphic rendering without heavy CPU load. Consider the 176-pin footprint for PCB layout constraints compared to larger packages like the ZIT6 which offers 2 Mbyte Flash.

Microcontrollers Part Context

This part belongs to the STM32F427/429 High-Performance Advanced Line series. These devices are designed for complex embedded applications, offering a significant performance boost over previous generations through the Cortex-M4 core and specialized accelerators. The series supports a wide range of peripherals and connectivity options for diverse industrial and consumer markets.

Microcontrollers Replacement Considerations

STM32F427ZIT6: Offers 2 Mbyte Flash instead of 1 Mbyte but uses a 144-pin LQFP package. STM32F429xx series: Provides similar performance with potentially higher Flash options and additional peripherals, often in larger packages.
