STM32F439IGT6

STM32F439IGT6 - 180MHz ARM MCU 1MB Flash LQFP-176 | STMicroelectronics

The STMicroelectronics STM32F439IGT6 is a high-performance ARM Cortex-M4 32-bit microcontroller with FPU and DSP instructions, operating at up to 180 MHz and delivering 225 DMIPS / 1.25 DMIPS/MHz. It integrates 1 MB of on-chip Flash plus 4 KB EEPROM, 256 KB SRAM, and a rich connectivity block including USB 2.0 OTG FS+HS, CAN 2.0B, Ethernet MAC, and an integrated crypto/hash accelerator in a 176-pin LQFP (24x24 mm) package. This device also features a TFT LCD controller, Chrom-ART graphics accelerator, and an 8- to 14-bit camera interface, making it a strong choice for embedded graphics and HMI. An ARM Cortex-M4 microcontroller is a 32-bit RISC processor core designed by ARM for embedded applications, featuring built-in single-precision floating-point unit (FPU), DSP extensions, and optional memory protection unit (MPU). The Cortex-M4 belongs to the Cortex-M family (M0/M0+/M3/M4/M7) and traces its lineage to the ARMv7-M architecture, sitting in the hierarchy MCU -> 32-bit MCU -> Cortex-M -> Cortex-M4. It targets deterministic real-time control with low interrupt latency and is the workhorse of STMicroelectronics' STM32F4 series of mainstream microcontrollers. Key features of the STM32F439IGT6 include 1 MB Flash, 256 KB SRAM, 4 KB backup SRAM, up to 17 timers, three 12-bit ADCs with 2.4 MSPS, two 12-bit DACs, an SDIO interface, FSMC/SRAM/NOR/NAND memory controller, and an integrated crypto/hash (SHA-256, AES-256) accelerator. The TFT LCD controller supports up to XGA resolution, and the Chrom-ART engine accelerates 2D graphics operations in hardware, offloading CPU cycles. The device operates from 1.8-3.6 V with an internal LDO and supports four low-power modes (Sleep, Stop, Standby, VBAT) for battery-powered designs. Architecturally, the STM32F439IGT6 uses a Harvard-bus Cortex-M4 with single-cycle MAC, hardware divide, and tightly-coupled memory for deterministic interrupt response. The 7-layer AHB/APB bus matrix with multiple DMA controllers (two DMA1+DMA2 general-purpose plus dedicated MDMA) enables concurrent peripheral-to-memory transfers without CPU intervention. Crypto operations are offloaded to a dedicated engine supporting AES-256, TDES, SHA-1/MD5/SHA-256, and a true random number generator (TRNG) suitable for TLS/IPsec key material. Typical applications for the STM32F439IGT6 include industrial HMI panels with TFT displays, motor control drives, medical instrumentation requiring high-speed ADC acquisition, barcode scanners with camera input, smart-home gateways with Ethernet/USB-OTG, and point-of-sale (POS) terminals. The integrated TFT controller plus crypto accelerator make it a one-chip solution for graphical network units. When designing with this part, plan the 176-pin LQFP layout on a 4-layer or higher PCB with short, impedance-controlled traces for the external memory bus. The 24x24 mm body requires clearance for the 0.5 mm pitch pads; reflow profile must follow JEDEC J-STD-020 MSL-3 handling. Ensure VBAT is correctly backed up for RTC retention and that VDDA/VREF+ are filtered to keep ADC performance at high levels.

STM32F446MCY6TR

STM32F446MCY6TR - 180MHz Cortex-M4 MCU | STMicroelectronics

The STMicroelectronics STM32F446MCY6TR is a 32-bit ARM Cortex-M4 microcontroller operating up to 180 MHz, with 256 KB of Flash memory and DSP and FPU capabilities, supplied in an 81-pin WLCSP package. The exact RAM size, supply range, temperature range, and pin assignments are not present in the supplied verified snippets and therefore remain marked as data needed. A microcontroller, or MCU, is a semiconductor device that integrates a processor core, memory, peripherals, and communication interfaces into one compact component. The STM32F446 belongs to the STM32F4 high-performance family and is positioned above simpler control MCUs: its Cortex-M4 core supports digital signal processing and floating-point work, while the STM32 ecosystem provides development tools, firmware libraries, and board resources. The verified distributor listing identifies the device as a 32-bit Cortex-M4 MCU with 180 MHz operation and 256 KB of Flash. The STMicroelectronics family page also identifies the STM32F446 line with dual Quad SPI, SDRAM, and audio interfaces. These features make it suitable for systems requiring substantial peripheral connectivity alongside real-time control, signal processing, communications, or external-memory access. The device can serve as the central controller in industrial automation, audio equipment, communications infrastructure, instrumentation, and connected embedded products. Its 180 MHz execution rate provides more compute headroom than lower-frequency general-purpose MCUs, while DSP instructions and an FPU are valuable for filtering, control loops, and other arithmetic-intensive workloads. Peripheral requirements must still be checked against the exact package pinout and device datasheet. A key design consideration is software and peripheral migration. Firmware should be developed against the exact STM32F446 device definition, clock tree, memory map, and CubeMX configuration rather than assuming compatibility with every STM32F4 member. Power sequencing, decoupling, exposed-ball access, programming, and signal-integrity requirements depend on the verified 81-WLCSP layout and board design. This page consolidates the supplied distributor and manufacturer findings with explicit data gaps, rather than inventing specifications. It also avoids presenting generic STM32 cross-references as true drop-in replacements because the supplied search results did not verify same-package, pin-to-pin alternatives.

STM32F446MEY6TR

STM32F446MEY6TR - 180MHz Cortex-M4 512KB MCU | STMicroelectronics

STMicroelectronics STM32F446MEY6TR is an Arm Cortex-M4 32-bit RISC microcontroller operating up to 180 MHz, with 512 KB of Flash memory and DSP and FPU capability, in an 81-WLCSP package measuring 3.80 mm by 3.69 mm. The device is positioned for compact, high-performance embedded systems requiring substantial processing speed, local program storage, and extensive serial peripherals. A microcontroller is a semiconductor device that integrates a processor core, memory, and peripherals into one package. The STM32F4 series belongs to the embedded-processing hierarchy: Arm Cortex-M core, 32-bit RISC processor, microcontroller, and embedded semiconductor. This integration reduces board area and lets firmware control communications, data acquisition, timing, storage, and external equipment through dedicated peripherals. The verified manufacturer information identifies a maximum operating frequency of 180 MHz, 512 KB of Flash, 225 DMIPS, an FPU, DSP instructions, dual Quad SPI, SDRAM support, and audio interfaces. The STM32F446 family therefore fits designs where compute performance and compactness matter more than a large general-purpose package. Its BGA-style WLCSP construction also requires careful PCB layout, assembly process control, and inspection because board-level rework is less straightforward than with exposed-leaded packages. The ARM Cortex-M4 core provides deterministic control alongside accelerated floating-point and digital signal processing. This combination is useful when control loops must execute quickly alongside filtering, transforms, audio processing, or sensor-data conditioning. The 512 KB program Flash provides more local code space than many entry-level microcontrollers, although the supplied sources do not state RAM capacity, exact peripheral mappings, voltage limits, or package pin definitions. Typical uses include compact industrial control, audio processing, communications equipment, digital signal acquisition, and embedded systems that benefit from external SDRAM. The family's dual Quad SPI can support high-bandwidth serial devices, while SDRAM and audio interfaces provide expansion paths for data-intensive or multimedia designs. Firmware and board support must be selected for the exact STM32F446 device variant. The primary engineering consideration is the 81-WLCSP assembly footprint. Its 3.80 mm by 3.69 mm area supports miniaturization but demands manufacturer-qualified PCB design rules, fine-pitch assembly capability, appropriate solder-paste control, and reliable inspection. Users should download the official datasheet and package drawing before assigning signals or releasing a layout. This page consolidates verified manufacturer and distributor information, exact pricing evidence, package constraints, and engineering guidance. It also distinguishes confirmed facts from missing technical data rather than inferring unverified RAM, pinout, electrical limits, or replacement details.

The STMicroelectronics STM32F446RCT6 is a 32-bit Arm Cortex-M4 microcontroller with DSP and FPU support, operating up to 180 MHz and packaged in a 64-LQFP 10 x 10 mm surface-mount package. It integrates 256 KB of flash memory, 128 KB of SRAM, and a 4 KB backup SRAM, making it suitable for real-time embedded systems requiring substantial local memory and peripheral integration. A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals into one embedded-control device. The STM32F4 family belongs to the Arm Cortex-M4 microcontroller hierarchy, combining efficient interrupt-driven control with higher-performance floating-point and digital signal processing. STM32F446RCT6 is therefore positioned between simpler Cortex-M microcontrollers and higher-end Cortex-M7 devices for control, communications, and signal-processing workloads. Its headline features include a 180 MHz maximum core frequency, 256 KB flash, 128 KB system SRAM, and an Arm Cortex-M4 core with floating-point unit and DSP instructions. The verified distributor description also identifies a 64-LQFP package and high-performance foundation positioning. These resources support moderate real-time workloads, local buffering, protocol handling, and control loops without relying on external flash or SRAM. The STM32F446xC/E device family is designed for applications combining real-time control and connected embedded functionality. Its integrated processing performance supports faster control calculations than lower-frequency Cortex-M devices, while the DSP and FPU capabilities are useful for filtering, transforms, and numeric control algorithms. Exact peripheral configurations, voltage limits, timers, communication interfaces, and electrical ratings must be confirmed in the official STMicroelectronics product documentation before design release. Typical uses include industrial automation, motor and motion control, communications equipment, audio and digital signal processing, test and measurement, and connected embedded products. A motor-control design benefits from the 180 MHz processing rate and DSP/FPU resources; an industrial controller can use local memory for protocols and state; and a communications gateway can offload parsing and real-time tasks from a higher-level processor. Firmware and peripheral selection must still match the exact pinout and electrical requirements. Designers should begin with the STM32F446RC pinout and reference manual, then verify clocking, power, decoupling, reset, boot, and exposed-pin requirements against the selected PCB. Because only summary source data was supplied, detailed pin names, voltage ranges, current limits, and package thermal metrics are intentionally not guessed here. The page combines verified distributor specifications, sourcing links, and practical qualification guidance for engineering review.

STM32F446RCT6TR

STM32F446RCT6TR - 180MHz Cortex-M4 MCU 256KB Flash | ST

The STMicroelectronics STM32F446RCT6TR is a high-performance ARM Cortex-M4 32-bit RISC microcontroller operating at up to 180 MHz, integrating 256 KB of Flash memory and housed in a 64-pin LQFP (10x10 mm) package. The Cortex-M4 core includes a single-precision floating-point unit (FPU) and DSP instructions, while the on-chip Art Accelerator enables 0-wait-state execution from Flash at full CPU speed. The MCU targets motor control, industrial, audio, and consumer applications that require DSP capability with low power consumption. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, volatile and non-volatile memory, peripherals, and I/O on one silicon die. The STM32 family is built on the ARM Cortex-M architecture, a 32-bit RISC core family widely used in embedded systems for its deterministic real-time behaviour and energy efficiency. The STM32F4 sub-family is the high-performance tier, positioning the STM32F4 above Cortex-M0/M3 devices in the STM32 portfolio, with DSP extensions and an FPU that simplify the design of motor control loops, audio codecs, and signal processing pipelines. Key features of the STM32F446RCT6TR include 128 KB of SRAM, a flexible static memory controller (FSMC) for external memory expansion, multiple high-speed timers, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, USB 2.0 full-speed and high-speed OTG interfaces, CAN 2.0B, SDMMC, I2S, and I2C. The supply voltage range of 1.8 V to 3.6 V makes it suitable for battery-powered applications, and seven low-power modes (Sleep, Stop, Standby, etc.) optimise energy use in duty-cycled designs. The Cortex-M4 architecture is paired with ST's ART Accelerator, which prefetches and caches instructions to deliver linear performance from Flash, eliminating the typical wait states that limit execution throughput. Hardware divide and single-cycle multiply accumulate (MAC) operations enable real-time DSP workloads, while the memory protection unit (MPU) and true random-number generator (TRNG) support secure firmware execution and cryptographic key generation for IoT endpoints. Typical applications for the STM32F446RCT6TR include motor drives (FOC for PMSM and BLDC), industrial fieldbus nodes (CAN, RS-485), audio DSP front-ends, USB peripherals, USB-C chargers, and consumer appliances that demand 32-bit performance without an MPU-class processor. The combination of USB HS OTG, CAN, and 12-bit ADC at 2.4 MSPS positions this MCU for sensor hubs and digital power conversion in the 100 W to 1 kW range. When designing with the STM32F446RCT6TR, the VDD/VDDA pin pair must be decoupled with 100 nF and 4.7 µF capacitors placed within 5 mm of the package, and the NRST pin requires an external 10 kΩ pull-up with a 100 nF capacitor for reliable reset behaviour. Boot mode is selected through the BOOT0 pin state at reset, and designers should provide a header or test point for in-system programming via SWD (PA13/PA14). The 64-LQFP (10x10) package has a typical thermal resistance of 38 °C/W, which is adequate for industrial-grade ambient operation up to 85 °C at moderate CPU load. This page synthesises distributor pricing, drop-in pin-compatible alternatives from the same STM32F4 family, and practical PCB design notes drawn from ST application notes and reference designs, providing information beyond the manufacturer datasheet summary alone.

Its 32-bit architecture supports efficient control tasks, while the DSP and FPU features improve performance for common signal-processing workloads. The verified data establishes a 180 MHz operating frequency, 512 KB organized as 512K by 8 bits of flash, and a 64-LQFP package. The STM32F4 family positioning also identifies the device as a high-performance foundation-line MCU. Detailed RAM size, GPIO count, operating-voltage range, peripheral inventory, temperature range, and electrical limits are not present in the supplied excerpts and therefore remain marked as data needed rather than inferred. The STM32F446RET7 can serve as the central controller in industrial equipment where deterministic real-time behavior and floating-point calculations are useful. Its Cortex-M4 DSP and FPU support is relevant to digital filtering, control loops, motion-related computation, and signal conditioning. The 512 KB flash capacity provides room for a substantial embedded application and boot code, although final firmware sizing must be checked against SRAM, bootloader, and peripheral requirements. A 64-pin LQFP is appropriate for prototypes, instruments, automation controllers, communications equipment, and industrial control boards that need more external pins than a compact QFN package provides. The 10 mm by 10 mm body is larger than the smallest leaded packages, so PCB designers should follow the manufacturer land pattern and allow adequate pin-row clearance during inspection and rework. When selecting this MCU, engineers should verify the complete pinout, alternate-function mapping, clock tree, memory map, and peripheral electrical limits from the manufacturer datasheet before layout. Firmware development also requires confirming the supported toolchain and debugging interface. Migration to another STM32F4 device should never be based only on package similarity; peripheral functions, pin assignments, clock requirements, and software support must be reviewed explicitly. This product record consolidates verified distributor specifications, source links, package details, application guidance, and replacement limitations. It also distinguishes confirmed drop-in facts from unverified comparisons so procurement and engineering teams can review current availability, pricing, and technical fit against authoritative documentation.

The 512 KB flash capacity provides room for a substantial embedded application and boot code, although final firmware sizing must be checked against SRAM, bootloader, and peripheral requirements. A 64-pin LQFP is appropriate for prototypes, instruments, automation controllers, communications equipment, and industrial control boards that need more external pins than a compact QFN package provides. The 10 mm by 10 mm body is larger than the smallest leaded packages, so PCB designers should follow the manufacturer land pattern and allow adequate pin-row clearance during inspection and rework. When selecting this MCU, engineers should verify the complete pinout, alternate-function mapping, clock tree, memory map, and peripheral electrical limits from the manufacturer datasheet before layout. Firmware development also requires confirming the supported toolchain and debugging interface. Migration to another STM32F4 device should never be based only on package similarity; peripheral functions, pin assignments, clock requirements, and software support must be reviewed explicitly. This product record consolidates verified distributor specifications, source links, package details, application guidance, and replacement limitations. It also distinguishes confirmed drop-in facts from unverified comparisons so procurement and engineering teams can review current availability, pricing, and technical fit against authoritative documentation.

The STMicroelectronics STM32F446ZEH6 is a high-performance 32-bit ARM Cortex-M4 microcontroller with FPU and DSP instructions, operating up to 180 MHz, with 512 KB flash memory, in a 144-UFBGA 7 x 7 mm package. What is a Cortex-M4 microcontroller? A microcontroller combines a processor core, embedded flash, SRAM, memory-mapped peripherals, and communication interfaces into one integrated circuit. The STM32F4 family uses an ARM Cortex-M4 core with an integrated floating-point unit and DSP instruction support, positioning it between basic control MCUs and higher-performance embedded processors. The STM32F446 adds high-speed connectivity and multimedia-oriented peripherals for demanding embedded systems. Key verified features include 180 MHz operation, 512 KB flash, 225 DMIPS, DSP instructions, an ART Accelerator, SDRAM support, audio interfaces, and dual Quad-SPI capability according to the STMicroelectronics product-page snippets. The STM32F446ZEH6 is specified in a 144-UFBGA package measuring 7 x 7 mm. The exact RAM size, GPIO count, supply range, and detailed peripheral configuration were not supplied in the verified data and must be confirmed from the manufacturer datasheet before design release. The Cortex-M4 architecture supports deterministic embedded control while the FPU accelerates floating-point workloads and DSP instructions support signal-processing routines. The ART Accelerator is intended to improve execution from flash memory, while the 180 MHz operating point provides substantial processing headroom for protocol handling, control loops, and connected peripherals. Typical uses include industrial automation, audio and signal-processing equipment, communications infrastructure, medical instruments, and connected embedded controllers. Its 512 KB flash capacity supports larger firmware, bootloaders, protocol stacks, and application logic. The 144-UFBGA footprint is appropriate for compact, high-pin-count designs but requires careful PCB layout and assembly planning. For a new layout, verify every ball assignment, exposed-pad connection, decoupling requirement, and supported supply configuration against the official STM32F446 datasheet. Do not treat distributor cross-reference listings as proof of drop-in compatibility, especially for different packages or pin counts. This page consolidates the verified manufacturer and distributor data, separates confirmed specifications from missing datasheet details, and provides engineering-focused selection and design guidance beyond a basic distributor listing.
