STM32F446ZEJ6TR 概要
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.

主な用途
STM32F446ZEJ6TR の用途: 6 件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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

設計ノート
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.
