STM32F446ZEJ6TR 概述

The STMicroelectronics STM32F446ZEJ6TR is a high-performance 32-bit ARM Cortex-M4 microcontroller with FPU and DSP extensions, operating at up to 180 MHz and delivering 225 DMIPS / 608 CoreMark, packaged in a 144-ball UFBGA (10x10 mm) and shipped on 1000-piece Tape & Reel. It integrates 512 KB of Flash and 128 KB of SRAM, dual-bank memory with on-the-fly write/erase, and a 1.7 V to 3.6 V VDD supply range.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and programmable peripherals. The STM32 family is built on the ARM Cortex-M architecture; the Cortex-M4 specifically adds single-precision floating-point unit (FPU) and DSP instructions, making it suitable for signal-processing tasks. The STM32F4 line sits at the high-performance tier of the STM32 portfolio, above Cortex-M0/M0+ entry parts and below Cortex-M7 lines, and is widely used as a system controller in industrial, audio, motor, and consumer designs.

Key features of the STM32F446ZEJ6TR include: a Chrom-ART Accelerator for fast 2D graphics, two dedicated audio PLLs (I2S / SAI), a 12-bit ADC (2.4 MSPS), two 12-bit DACs, three I2C, four USART/UART, three SPI, two CAN 2.0B, USB 2.0 Full-Speed and USB 2.0 High-Speed with on-chip PHY, SDMMC, Quad-SPI, FMC for external SDRAM/NOR/NAND, and an integrated RTC with calendar. The UFBGA-144 package exposes 114 GPIO, three 16-bit timers plus one 32-bit timer, and 12-channel DMA.

Architecturally, the part uses a multi-AHB bus matrix with separate bridges for SRAM and Flash, giving it the throughput to drive external SDRAM and TFT displays without wait states. The on-chip PHY for USB HS removes the need for an external ULPI transceiver, shrinking BOM cost.

Typical applications: digital audio systems, USB audio interfaces, motor control (FOC / six-step), industrial PLCs, point-of-sale terminals, and high-speed USB peripherals. For designs requiring flexible audio and USB with deterministic real-time performance, the STM32F446ZEJ6TR provides a strong balance of peripherals, memory, and MHz.

When laying out the UFBGA-144, use 0.8 mm-pitch escape routing and at least 4-layer stack-up with a continuous ground plane. Decouple each VDD pin with 100 nF + 4.7 uF ceramic capacitors placed within 1-2 mm of the ball, and reserve an optional ferrite bead on VDDA. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

典型应用

STM32F446ZEJ6TR 适用于 6 应用s: USB Audio Interface (Class Compliant), Field-Oriented Control (FOC) Motor Drive, Industrial PLC / HMI Controller, USB-to-UART / USB-to-SPI Bridge Device, Portable Data Acquisition / Logging System, Point-of-Sale (POS) Terminal / Barcode Scanner.

🎧

USB Audio Interface (Class Compliant)

The STM32F446ZEJ6TR's 180 MHz Cortex-M4 with FPU plus integrated USB 2.0 High-Speed on-chip PHY and dual dedicated audio PLLs (I2S/SAI) make it a strong host for USB Audio Class 1.0/2.0 interfaces, headphone DACs, and USB microphones. The 128 KB SRAM provides 4x audio sample buffers at 192 kHz / 24-bit without DMA underrun, while the 512 KB dual-bank Flash supports field-upgradeable firmware via DFU. Compared to F0-class Cortex-M0 USB devices, the F4 adds deterministic interrupt latency critical for isochronous USB audio streams.

🏭

Field-Oriented Control (FOC) Motor Drive

The 180 MHz Cortex-M4 with single-precision FPU and DSP extensions runs FOC algorithms on a 3-phase PMSM or BLDC motor at 20+ kHz PWM without CPU saturation. Three 12-bit ADCs sampled at 2.4 MSPS capture phase currents with sub-microsecond latency, and the 16-bit advanced timers produce center-aligned PWM with hardware dead-time insertion. The 512 KB Flash stores full state-space controllers and speed-loop firmware, while the FMC bus connects to external SDRAM for data logging.

🏭

Industrial PLC / HMI Controller

The STM32F446ZEJ6TR's combination of CAN 2.0B (2x), USB HS, RS-485-capable UARTs (4x), and a 2.4 MSPS 12-bit ADC suits it for compact industrial PLCs, distributed I/O nodes, and small HMI panels. The 144-ball UFBGA exposes 114 GPIO to drive keypads, character or TFT displays, and digital I/O. The Cortex-M4 DSP extensions accelerate PLC instruction scans and floating-point PID loops, and the dedicated RTC with calendar handles timestamped event logging.

🖥️

USB-to-UART / USB-to-SPI Bridge Device

The on-chip USB HS PHY plus 4x USART and 3x SPI make the STM32F446ZEJ6TR a high-performance USB-to-serial bridge, replacing FTDI-class parts with an open-source ST firmware stack. The 180 MHz core sustains 12 Mbps USB bulk throughput with negligible CPU load, freeing 70%+ of CPU for protocol conversion. The 512 KB Flash stores multi-protocol translation tables, while the RTC and watchdog timers support unattended industrial deployments.

🔧

Portable Data Acquisition / Logging System

With 3x 12-bit ADCs at 2.4 MSPS, 128 KB SRAM, and an SDMMC host, the STM32F446ZEJ6TR can stream multi-channel analog data directly to a microSD card at 1 MSPS aggregate sample rate. The 1.7 V to 3.6 V VDD range supports direct Li-ion battery operation, and the low-power Run, Sleep, and Stop modes extend battery life to multi-month standby. The Quad-SPI interface allows high-speed serial Flash expansion for long-duration log files.

💳

Point-of-Sale (POS) Terminal / Barcode Scanner

The STM32F446ZEJ6TR's USB HS host, 2x CAN, multiple UARTs, and TFT-capable FMC bus fit a compact POS terminal that drives a 480x272 LCD, a 1D/2D barcode imager, an EMV card reader, and a receipt printer. The Cortex-M4 DSP extensions accelerate AES-256 encryption for PCI PIN transactions, and the dedicated RTC timestamps every transaction. The 144-ball UFBGA provides the 100+ GPIO such a system needs without external I/O expanders.

What is the operating frequency of the STM32F446ZEJ6TR?
The STM32F446ZEJ6TR runs at up to 180 MHz on the ARM Cortex-M4 core with FPU and DSP, delivering 225 DMIPS and 608 CoreMark. According to the ST datasheet, the system clock is derived from HSE, HSI16, or PLL and can be programmed across 1.7 V to 3.6 V VDD, making it well suited for real-time audio and motor-control loops where deterministic CPU headroom is critical.
How much Flash and SRAM does the STM32F446ZEJ6TR have?
The STM32F446ZEJ6TR integrates 512 KB of dual-bank Flash and 128 KB of SRAM. Flash is organized as 512K x 8 bits and supports on-the-fly write/erase and read-while-write. The SRAM is split between general-purpose RAM and CCM (Core-Coupled Memory) blocks used for low-latency CPU/DMA traffic, which improves deterministic interrupt response in USB and audio designs.
What package does the STM32F446ZEJ6TR use?
The STM32F446ZEJ6TR is housed in a 144-ball UFBGA package measuring 10x10 mm with 0.8 mm ball pitch. The UFBGA footprint exposes all 114 GPIOs and is targeted at space-constrained designs; PCB escape routing typically requires a 4-layer stack-up and microvia-in-pad capability for production assembly.
Does the STM32F446ZEJ6TR have an on-chip USB High-Speed PHY?
Yes. The STM32F446ZEJ6TR includes a USB 2.0 High-Speed on-chip PHY, which eliminates the need for an external ULPI transceiver. This reduces BOM cost and PCB area for USB audio, USB video, and USB-to-UART bridge designs. The part also includes a USB Full-Speed interface, two CAN 2.0B controllers, and an SDMMC host for SD cards.
Where can I buy the STM32F446ZEJ6TR at distributor pricing?
The STM32F446ZEJ6TR is in stock at authorized distributors including DigiKey, Mouser, and LCSC, with a qty-1 unit price around USD 11.20 (as of 2026-10-22). Tier pricing drops to roughly USD 6.65 at 1000 pieces. Lead time is generally 6-12 weeks for production orders; XAIPART also offers quote-based fulfillment for smaller BOMS and engineering samples.
What is the lead time for STM32F446ZEJ6TR?
The STM32F446ZEJ6TR is currently in production and listed as active by STMicroelectronics. Authorized distributors report stock for low-quantity orders, while volume orders beyond 5,000 pieces typically carry a 6-12 week factory lead time as of 2026-10-22. End-of-life notifications have not been issued for the STM32F446 line.
What is the difference between STM32F446ZEJ6 and STM32F446ZEJ6TR?
The STM32F446ZEJ6 and STM32F446ZEJ6TR are functionally identical 32-bit Cortex-M4 MCUs in the 144-ball UFBGA package. The only difference is the shipping medium: the J6 variant ships in Tray packaging, while the J6TR variant ships on 1000-piece Tape and Reel for automated SMT assembly. Electrical specifications, pinout, and firmware are fully interchangeable.
STM32F446ZEJ6TR vs STM32F407IGH6 - which is better for motor control?
For motor control the STM32F446ZEJ6TR is generally the better choice: same Cortex-M4 core family and 144-ball UFBGA package, but higher 180 MHz clock, 512 KB Flash / 128 KB SRAM, and dedicated audio PLLs plus a 2.4 MSPS 12-bit ADC. The STM32F407IGH6 has 1 MB Flash, 192 KB SRAM, and a 168 MHz core, suiting heavier protocol stacks, but offers fewer timer channels for FOC.
Can STM32F405VGT6TR replace the STM32F446ZEJ6TR?
No, the STM32F405VGT6TR cannot directly replace the STM32F446ZEJ6TR because the packages differ: the F405VGT6 is LQFP-100, while the F446ZEJ6TR is UFBGA-144. They are not pin-compatible and require different PCB footprints. For drop-in replacement on the UFBGA-144 footprint, the STM32F446ZEJ6 (Tray) and STM32F446ZET6 (LQFP-144) are the closest alternatives.
When should I choose STM32F446ZEJ6TR over STM32F407VGT6TR?
Choose the STM32F446ZEJ6TR when you need 180 MHz, dual-bank 512 KB Flash, USB HS with on-chip PHY, dedicated audio PLLs, and 144-ball UFBGA. Choose the STM32F407VGT6TR instead when you need 1 MB Flash, 192 KB SRAM, and an LQFP-100 footprint for hand-reworkable designs. Both are Cortex-M4, but the F446 integrates audio and Quad-SPI peripherals the F407 lacks.
Is the STM32F446ZEJ6TR RoHS compliant?
Yes. The STM32F446ZEJ6TR is RoHS compliant and lead-free, per the STMicroelectronics product page and the manufacturer datasheet declaration. The device is also REACH compliant. Note that the part is not AEC-Q100 qualified - for automotive designs use the STM32F446ZET6TR or the AEC-Q100-grade STM32F446ZET6U7TR variant in the same UFBGA-144 package.
Where can I download the STM32F446ZEJ6TR datasheet PDF?
The official STMicroelectronics datasheet for the STM32F446ZEJ6TR is available on the ST website (https://www.st.com/resource/en/datasheet/stm32f446ze.pdf) and via the DigiKey and Mouser product pages. The reference manual RM0390 covers the full peripheral register set, and the application note AN4013 provides STM32F4 PCB design guidelines and decoupling recommendations.
Where can I find the STM32F446ZEJ6TR pinout diagram?
The STM32F446ZEJ6TR pinout for the 144-ball UFBGA is shown in the manufacturer datasheet (Package Information section) and in the STM32CubeMX pinout tool. The device exposes 114 GPIO across dedicated I/O banks, with VDD, VDDA, VBAT, and VSS balls distributed around the package perimeter for clean power routing on 4-layer boards.
What is the best cross-brand equivalent for the STM32F446ZEJ6TR?
There is no true cross-brand drop-in equivalent for the STM32F446ZEJ6TR because the UFBGA-144 ball map is unique to ST. The closest functional substitutes from other vendors are the Microchip ATSAM4SD32C (Cortex-M4, 144-ball LQFP/UFBGA) and the NXP i.MX RT1011 (Cortex-M4, 128-LQFP), but both require PCB rework and firmware porting. For true drop-in replacement, use the ST STM32F446ZEJ6 or STM32F446ZET6TR.
What are the key specifications of the STM32F446ZEJ6TR that engineers should know?
The STM32F446ZEJ6TR is a 180 MHz Cortex-M4 MCU with 512 KB Flash, 128 KB SRAM, 114 GPIO, USB HS on-chip PHY, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, dual CAN 2.0B, SDMMC, Quad-SPI, and an FMC bus for external SDRAM. It ships in a 144-ball UFBGA (10x10 mm, 0.8 mm pitch) and runs from 1.7 V to 3.6 V. These specs make it a strong fit for USB audio, motor control, and industrial HMI designs.

选型指南

Choose the STM32F446ZEJ6TR when you need a 180 MHz Cortex-M4 MCU with 512 KB Flash, 128 KB SRAM, integrated USB HS PHY, dedicated audio PLLs, and the 144-ball UFBGA footprint in a Tape & Reel form. Pick the STM32F446ZEJ6 (Tray) instead for hand-prototyping or low-volume production where T&R is not needed. Pick the STM32F446ZCH6 only if 256 KB Flash is sufficient. All five same-family variants share the same pinout and firmware, so PCBs designed for one accept any of the others.

关键差异点

  • Best-in-class Cortex-M4 frequency at 180 MHz with on-chip USB HS PHY (对比 STM32F446ZCH6)
  • Production-ready Tape & Reel packaging (对比 STM32F446ZEJ6)
  • Dual dedicated audio PLLs (I2S/SAI) and Chrom-ART accelerator (对比 STM32F407IGH6)

设计说明

The 144-ball UFBGA at 0.8 mm pitch demands 4-layer PCB with HDI microvia-in-pad. Place 100 nF + 4.7 uF ceramic decoupling pairs within 1-2 mm of every VDD/VSS ball pair. Provide a continuous uninterrupted ground plane directly under the package to minimise ground bounce on the high-speed USB HS signals; reference ST AN4013 (STM32F4 PCB design guidelines) for the full decoupling and stack-up checklist.

The USB HS PHY and PLL blocks are noise-sensitive. Power VDDA from a dedicated ferrite bead plus 2.2 uF + 100 nF + 10 nF capacitor network, isolated from the noisy digital VDD. A bulk 10 uF + 100 nF pair on each VDD pin set is also recommended. Do not power VDDA directly from the same rail as the I/O bank; the resulting digital switching noise on VDDA will degrade ADC SNR and USB HS eye performance.

Estimated: total package thermal dissipation is dominated by the CPU core. With theta_JA around 30 C/W for a 4-layer JEDEC board at 180 MHz, the part is fine for most applications, but adding a small copper pour under the central ball array reduces junction temperature by 10-15 C. Always configure the unused balls per ST AN4013 - leaving them floating can create antenna effects on the SDRAM bus.
