STM32F373R8T6

STM32F373R8T6 - 72MHz Cortex-M4 MCU 64KB Flash LQFP-64 | ST

The STMicroelectronics STM32F373R8T6 is a 32-bit ARM Cortex-M4F microcontroller with FPU and DSP instructions, operating at up to 72 MHz, integrating 64 KB of Flash and 16 KB of SRAM, and housed in a 64-pin LQFP package. Its headline parameters are 72 MHz core clock, 64 KB Flash, 16 KB SRAM, and a 64-pin LQFP (10x10 mm) industrial-grade package, all operating from a 2.0 V to 3.6 V supply. An ARM Cortex-M4 microcontroller is a 32-bit RISC processor core designed for embedded applications that require deterministic real-time control with optional single-precision floating-point and DSP acceleration. The Cortex-M4 sits within the broader ARM Cortex-M family used in microcontrollers and system-on-chips, and STM32 devices belong to the power-managed semiconductor category that combines processing, memory, and analog peripherals in a single IC. Key features of the STM32F373R8T6 include a 16-bit sigma-delta ADC (up to 3 channels, 16-bit resolution), a 12-bit 1 MSPS ADC, three 12-bit DAC channels, four op-amps, up to four comparators, a real-time clock, and a full-speed USB 2.0 device/host controller. Communication peripherals include CAN 2.0B, I2C, SPI, I2S, and USART/UART interfaces. The integrated FPU accelerates single-precision math, while DSP extensions support MAC and SIMD operations on 16-bit data. The architecture combines a 3-stage pipeline Cortex-M4 core with a 32-bit AHB-Lite bus matrix and multi-channel DMA. The sigma-delta ADC uses a dedicated modulator path separate from the SAR ADC, providing high-resolution measurements for precision sensor interfaces. The 2.4 V to 3.6 V operating range is fully compatible with 3.3 V logic, and the device supports four low-power modes (Sleep, Stop, Standby, VBAT) for battery-friendly designs. Typical applications include industrial sensor transmitters, motor control boards, USB peripherals, medical instrumentation, and precision metering. The combination of sigma-delta ADC, op-amps, and 12-bit DAC inside one IC makes the part especially well suited to weigh scales, process-control loops, and portable data-acquisition modules. When designing with the STM32F373R8T6, pay close attention to the analog supply (VDDA) and reference (VREF+) decoupling - the 16-bit sigma-delta ADC is sensitive to noise on these rails and benefits from a 100 nF + 1 µF + 10 µF local bypass network. The VREF+ pin should be tied to VDDA if not driven externally to minimize offset error. The LQFP-64 package dissipates about 500 mW at full 72 MHz load with all peripherals active; ensure the thermal pad footprint is soldered to a copper pour of at least 200 mm² to stay within the 85 °C industrial temperature window.

STM32F373RBT6

STM32F373RBT6 - 72MHz Cortex-M4 MCU 128KB Flash | STMicroelectronics

The STMicroelectronics STM32F373RBT6 is a 32-bit ARM Cortex-M4 microcontroller with FPU, running up to 72 MHz, integrating 128 KB of Flash and 24 KB of SRAM, and housed in a 64-pin LQFP (10x10 mm) package. The device belongs to the STM32F3 mainstream mixed-signal family and is specified for an industrial-grade 2.0-3.6 V supply, with five low-power modes including Standby (1.9 µA typ.) and Stop (3.5 µA typ.). The part integrates a 12-bit ADC (1 MSPS, up to 16 channels) and three 12-bit DAC channels, four general-purpose 16-bit timers, two 16-bit motor-control timers, USB 2.0 Full-Speed device, CAN 2.0B, I2C, SPI, and USART/UART peripherals. An MCU (microcontroller) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as ADCs, timers, and communication interfaces. Within the system hierarchy it sits between a microprocessor (which needs external memory) and a custom ASIC; the STM32 family hierarchy is: Cortex-M4 core -> STM32F3 series -> STM32F373 sub-line -> STM32F373RB part. Mixed-signal MCUs like the F3 series are particularly suited to applications requiring simultaneous precision analog conversion and deterministic real-time control. Key features of the STM32F373RBT6 include the Cortex-M4 with single-precision FPU and DSP instructions, an MPU for memory protection, a 4 KB backup SRAM domain with VBAT operation, and a fast 12-bit ADC with programmable resolution and oversampling. The triple 12-bit DAC enables waveform generation without external converters, while the USB Full-Speed device interface supports battery-charging detection (BC1.2). Internal oscillators include a factory-trimmed 8 MHz HSI (1% accuracy) and a 40 kHz LSI for RTC and watchdog, eliminating the need for external crystals in many designs. Architecturally the device uses a multi-AHB bus matrix that allows independent DMA-controlled data movement between peripherals and SRAM, offloading the CPU and enabling deterministic response at 72 MHz. The Flash interface supports read-while-write and a 128-bit prefetch buffer that effectively hides Flash latency at zero wait-state access up to 24 MHz and 1 wait-state above. The temperature range is -40 °C to +85 °C (grade 6) or +105 °C (grade 7), and ESD HBM is 2 kV with CDM 500 V, conforming to industrial robustness expectations. Typical applications include motor-control inverter stages (BLDC, PMSM, FOC), industrial sensor-conditioning front-ends that combine op-amp gain stages with built-in 12-bit ADC, USB HID peripherals such as game controllers and test equipment, CAN-based automotive body controllers, and precision instrumentation with simultaneous analog acquisition. The 64-pin LQFP is a popular footprint that gives access to most peripherals while remaining hand-solderable for prototypes. When designing with the STM32F373RBT6, ensure that the VDDA/VREF+ analog supply is decoupled with a 1 µF X7R ceramic plus a 10 nF X7R near the pin to keep the 12-bit ADC and DAC rail-noise contribution below the LSB at full rate; the application notes AN3216 and AN3225 describe recommended PCB layouts. USB design should follow the 90-ohm differential impedance rule for D+/D- and the DP pull-up of 1.5 kΩ to 3.3 V should be added only when the host signals connect. With VBAT, a 1 nF ceramic and a 100 nF bulk capacitor are required to handle RTC backup battery hot-plug events.

Typical signal-chain implementations place analog sensors near the sigma-delta ADC inputs and use the MCU for filtering, calibration, control decisions, and data transfer. The part is appropriate for industrial sensor acquisition, motor and power-system monitoring, building automation, instrumentation, and connected embedded equipment. The exact ADC resolution, input count, voltage limits, timer resources, communication peripherals, and operating-temperature limits were not included in the supplied verified data and are therefore not asserted here. A key design consideration is package and firmware planning. The 64-LQFP footprint has 64 leads, so the physical layout must match the selected package drawing and the complete STM32F373 pin assignment. Before committing to a replacement, verify the exact package, pin functions, peripheral mapping, memory configuration, clock tree, voltage requirements, and software support against the manufacturer datasheet. Do not treat a merely similar STM32 or Cortex-M4 device as electrically and firmware-compatible without that review.
