STM32F103RBH7

STM32F103RBH7 - 72MHz 128KB Cortex-M3 MCU | STMicroelectronics

The STMicroelectronics STM32F103RBH7 is a 32-bit ARM Cortex-M3 microcontroller operating up to 72 MHz, with 128 KB of Flash memory and a 64-pin TFBGA package measuring 5 x 5 mm. It belongs to the STM32F1 performance-line MCU family and combines deterministic embedded control with serial communications and general-purpose I/O in a compact surface-mount package. The verified listing identifies ARM Cortex-M3 architecture, 72 MHz operation, 128 KB Flash, and 64-TFBGA construction. A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and I/O into one device. The Cortex-M3 hierarchy places STM32F103RBH7 within ARM-based 32-bit embedded processors, microcontrollers, and the broader semiconductor category. It is suited to systems that require compact firmware execution, real-time control, and multiple serial interfaces without using a larger application processor. The verified part data specifies 32-bit processing, a 72 MHz maximum frequency, and 128 KB organized as 128K x 8 Flash. One distributor result also describes a wide I/O selection and available connectivity including USB, CAN, LIN, I2C, and SPI. These interfaces make the device useful when several peripheral buses must coexist. Exact peripheral counts, voltage ranges, RAM capacity, GPIO count, package dimensions, and electrical limits were not supplied in the provided data and therefore remain unconfirmed here. The STM32F103RBH7 is positioned for embedded control, communication gateways, instrumentation, and compact automation modules. Its 128 KB Flash footprint provides room for boot code, application logic, and communication handlers, while the 72 MHz Cortex-M3 core provides computational headroom for control loops. Firmware planning must nevertheless include the device's actual RAM, interrupt map, peripheral variants, clock limits, and pin multiplexing after those values are confirmed from the manufacturer datasheet. PCB design should provide a regulated supply, decoupling capacitors, ground-plane continuity, and clean routing for external interfaces. Because the verified package is a 64-pin TFBGA, assembly and inspection require a land pattern and via arrangement suitable for fine-pitch BGA construction. Do not substitute a package drawing from an LQFP STM32F103 variant, because the STM32F103RBH7 listing explicitly identifies TFBGA rather than LQFP. This data page consolidates exact distributor listings, availability and pricing references, package information, interface context, and replacement-analysis limits for the STM32F103RBH7. Unverified technical values are deliberately identified as missing rather than inferred. Engineers should use the manufacturer datasheet for final pin assignments, timing, electrical characteristics, memory, errata, and qualification decisions before release to production.

The STMicroelectronics STM32F103RBT6 is a 32-bit ARM Cortex-M3 microcontroller operating at 72 MHz, integrating 128 KB of single-bank Flash and 20 KB of SRAM in a 64-pin LQFP surface-mount package. It belongs to the ST medium-density STM32F1 performance line and is one of the most widely deployed Cortex-M3 MCUs in industrial control and communication modules. A microcontroller unit (MCU) is a single integrated circuit that combines a processor core, memory, and programmable peripherals into one device, forming the lowest layer of the embedded-system hierarchy: MCU -> microcontroller -> embedded processor -> system-on-chip. The ARM Cortex-M3 is a 32-bit RISC processor core optimized for cost-sensitive and power-conscious embedded control. The STM32F103 family was one of the first mainstream Cortex-M families adopted at scale across industrial electronics, in large part because of its rich peripheral set and pin compatibility across Flash derivatives. Key features include the 72 MHz Cortex-M3 core delivering 1.25 DMIPS/MHz, 128 KB on-chip Flash, 20 KB SRAM, a 2.0 V to 3.6 V supply range with a 3.3 V operating point, two 12-bit ADCs with up to 1 microsecond conversion time and up to 16 input channels, two I2C, two SPI, three USART, one USB 2.0 full-speed interface, one CAN 2.0B active controller, and seven 16-bit timers including PWM-capable channels. An 8 MHz high-speed internal RC oscillator and support for an external 4 to 16 MHz crystal allow flexible clocking without external components. Architecturally, the device uses an ARMv7-M Harvard structure with a three-stage pipeline and a Nested Vectored Interrupt Controller (NVIC) for low-latency interrupt response. An AHB/APB bus matrix allows peripheral DMA and core execution to proceed concurrently, while a Flash interface with prefetch buffer minimizes stalls when the 72 MHz core fetches instructions from Flash. Typical applications include industrial control nodes, motor-control auxiliary boards, USB and CAN communication modules, low-cost development platforms, and legacy 8-bit/16-bit MCU upgrades where the ARM tool ecosystem reduces software cost. Designers also use this device in smart-metering peripherals and low-cost HMIs. Design consideration: pin compatibility across the STM32F1 family means Flash upgrades from 128 KB to 256 KB (e.g., STM32F103RCT6) require no PCB change, but verify RAM sizing, peripheral count, and the 72 MHz maximum frequency when porting between derivative families. This page synthesizes distributor pricing, verified drop-in alternatives including the GD32F103RBT6 cross-brand P2P candidate and STM32F103RCT6 same-family upgrade, plus practical design notes not found in the manufacturer datasheet.

A 7-channel DMA controller offloads data transfers, and a nested vectored interrupt controller (NVIC) with 60 maskable interrupt vectors enables deterministic real-time response. The core supports single-cycle hardware multiply and division for efficient signal processing. Technically, the device operates from a 2.0 V to 3.6 V supply with dedicated VDDA/VSSA analog pins that isolate the ADC and PLL from digital supply noise. Power modes include Sleep, Stop, and Standby with wake-up in microseconds; typical run consumption is low enough for battery-powered designs. Flash supports 10,000 write cycles with embedded erase/write controllers, and true read-while-write operation permits EEPROM emulation. Typical applications include industrial control and PLC I/O modules, motor control and inverter boards using the advanced TIM1 timer, USB and CAN field devices, medical handheld instruments, and consumer appliances. Design consideration: keep VDDA well-decoupled (10 nF plus 1 uF) and provide a clean 3.3 V rail with 100 nF on every VDD pin pair; BOOT0 must be strapped to ground for flash boot. This page adds value beyond the datasheet by synthesizing distributor pricing, verified pin-compatible alternatives such as GigaDevice GD32F103, and practical design notes for second-sourcing and migration.

The STM32F103RCY6CTR provides 256 KB of Flash for program storage, 3 ADC channels, and a peripheral set covering USB, CAN, timers, and multiple serial communication interfaces. USB and CAN support respectively removable data exchange and robust controller-area-network communications. The 11 timers support periodic timing, input capture, output compare, encoder-related measurement, and motor-control sequencing, while the 3 ADC channels provide analog-to-digital conversion for sensing and feedback applications. The STM32F103 series is positioned by STMicroelectronics as its mainstream value line of high-density ARM-based microcontrollers. Its combination of Cortex-M3 processing, extensive timers, analog conversion, and communication peripherals allows a single device to consolidate functions that might otherwise require several discrete components. Software design should still account for the exact peripheral assignments and alternate-function settings listed in the manufacturer pin and reference documents. Typical applications include industrial control boards, IoT gateways, USB-connected instruments, CAN-based monitoring equipment, electronic meters, compact motor controllers, and low-power embedded products. The 64-UFBGA/WLCSP format is especially useful for space-sensitive products, but its fine pitch requires careful PCB layout, solder-paste control, X-ray inspection, and assembly-process qualification. Designers should review the package drawing, land pattern, exposed-pad or thermal requirements, and recommended PCB stack-up before layout. Firmware and peripheral configurations should be validated against the STM32F103 reference manual, especially for alternate-function pins, clock configuration, USB suspend behavior, and CAN timing. Because this package has a fine ball-grid pitch, assembly yield is as important as electrical performance. This product page consolidates the identified electrical characteristics, package information, sourcing guidance, alternative-device caveats, and practical implementation considerations into one engineering-focused resource. It also distinguishes true pin-compatible substitution from broader MCU equivalence, helping teams evaluate second sourcing without overlooking memory, firmware, timing, qualification, or PCB-change risks.

Background: An ARM Cortex-M3 microcontroller is a 32-bit RISC core with Thumb-2 instruction set, hardware divide, NVIC interrupt controller, and tightly coupled memory interfaces, designed for deterministic real-time embedded control. Within the broader taxonomy, the Cortex-M3 belongs to the ARM Cortex-M family -> 32-bit RISC microcontrollers -> embedded microcontrollers -> microprocessors -> semiconductors. The STM32F1 series is ST's mainstream Cortex-M3 line spanning low-, medium-, high-, and XL-density sub-families with progressively richer peripheral sets. Key specifications include a 2.0-3.6 V single supply range, 4-16 MHz crystal driver with internal 8 MHz RC and 40 kHz LSI for RTC, 12-bit ADC with up to 16 channels, two 12-bit DACs, an FS USB PHY, and a CAN 2.0B controller.

The 384 KB Flash capacity accommodates larger embedded applications than low-density STM32F1 devices, while the timer and ADC resources support motor control, signal monitoring, and data acquisition. The 64-pin package also provides 37 I/O ports. The STM32F1 architecture combines a deterministic general-purpose control core with dedicated peripheral blocks for timers, serial communications, analog conversion, USB, and CAN. Single-cycle multiplication and hardware division accelerate common control-loop operations without requiring separate arithmetic accelerators. Operation from a 2.0 V to 3.6 V supply range supports conventional embedded power systems, while the maximum 72 MHz clock provides a higher processing ceiling than the 16 MHz entry-level clock stated in one distributor record.

For PCB implementation, use the manufacturer's pinout and package drawing to assign power, ground, clock, reset, boot, and peripheral signals. Place decoupling capacitors close to the supply pins, provide a correctly designed clock and reset network, and preserve access to all programming and debug signals. Confirm the complete pin map against the manufacturer datasheet before routing a production board. This page combines the exact device configuration, verified manufacturer and distributor resources, drop-in candidate analysis, application guidance, and design-focused comparisons to support component selection, schematic review, PCB planning, and sourcing without reducing the STM32F103RFT6JTR to a basic catalog description.

STM32F103RFT6TR

STM32F103RFT6TR - 32-Bit 72MHz Cortex-M3 MCU | STMicroelectronics (Tape & Reel)

The STMicroelectronics STM32F103RFT6TR is a 32-bit ARM Cortex-M3 microcontroller operating at up to 72 MHz, with 768 KB of Flash memory, 96 KB of RAM, 51 I/O pins, and a 64-pin LQFP package measuring 10 mm by 10 mm. It is an XL-density performance-line STM32F1 series MCU designed for embedded systems requiring substantial memory, extensive connectivity, and multiple peripheral functions. An STM32F1 microcontroller is a 32-bit embedded-control component combining a processor core, program Flash, static RAM, GPIO, timers, analog converters, and communication interfaces. STM32F1 devices belong to the microcontroller hierarchy, where they sit between a general-purpose microprocessor and simpler fixed-function embedded controllers. The Cortex-M3 core uses a reduced-instruction architecture optimized for control workloads, interrupt handling, and real-time embedded applications. The supplied specifications identify the STM32F103RFT6TR with 768 KB program Flash, 96 KB RAM, 51 I/O pins, a 72 MHz operating frequency, and a 64-LQFP package. The device also belongs to the STM32F103 XL-density family and is associated with USB, CAN, timers, ADCs, and communication interfaces. These features support designs requiring multiple serial peripherals, control-loop timing, data acquisition, and external connectivity rather than a simple GPIO-only control node. The STM32F103RFT6TR is suitable for industrial automation, motor control, communications, USB-enabled embedded products, CAN-connected equipment, and general-purpose control boards. Its 51 available I/O pins provide connectivity for sensors, actuators, displays, memory, transceivers, and status indicators. The 768 KB Flash capacity offers room for a larger application, bootloader, protocol stack, or logging subsystem than lower-density STM32F1 variants, while 96 KB RAM supports buffered communications and control data. The 64-LQFP package is mechanically suited to leaded PCB assembly and provides a documented alternative to smaller fine-pitch packages when inspection, rework, or hand assembly matters. Designers should confirm the exact pinout, electrical limits, clock configuration, startup behavior, and peripheral assignments from the manufacturer datasheet before finalizing a board. STM32F103RFT6TR is supplied in tray packaging according to the verified distributor data. This product page combines distributor specifications, manufacturer-related sourcing information, and engineering-oriented application guidance. It also records the verified availability of same-footprint alternatives without treating a pin-compatible candidate as automatically equivalent in firmware, timing, or analog behavior. The STM32F103RFT6TR is therefore best understood as a high-memory STM32F1 MCU platform selected when its documented resources and package match the system requirements.
