STM32F103R6T6ATR - 72MHz 32-bit MCU | STMicroelectronics (Tape & Reel)

The STMicroelectronics STM32F103R6T6ATR is a 32-bit ARM Cortex-M3 microcontroller operating at up to 72 MHz, with 32 KB of Flash memory and 2.5 V or 3.3 V supply operation, housed in a 64-pin LQFP package measuring 10 x 10 mm. It is designed for compact embedded-control systems requiring deterministic real-time processing, serial communications, and general-purpose peripheral integration. A microcontroller is a semiconductor device that integrates a processor core, Flash program memory, RAM, clocks, interrupt controllers, and peripherals on one integrated circuit. The STM32F103R6T6ATR belongs to the STM32F1 performance-line family, combining an ARM Cortex-M3 RISC core with the broader microcontroller hierarchy of embedded processor, semiconductor, and electronic control system. Its 32-bit architecture supports efficient handling of control algorithms, communication protocols, and digital logic. The principal verified features include a 72 MHz Cortex-M3 core, 32-bit processing, 32 KB of Flash, 64-pin LQFP packaging, and operation from 2.5 V or 3.3 V. The manufacturer describes the STM32F103x4 and STM32F103x6 devices as a performance-line family for 32-bit RISC processing. USB, CAN, and timer capabilities are associated with this family in the available family documentation, although complete peripheral details and electrical limits are not included in the supplied excerpts. The 64-pin LQFP package exposes substantially more I/O than smaller 48-pin STM32F103 variants, making the device useful where an application requires multiple serial interfaces, timers, analog inputs, or digital control signals. Its 72 MHz clock rate provides more instruction throughput than lower-frequency Cortex-M3 devices while retaining compatibility with the established STM32 embedded ecosystem. Exact RAM capacity, flash organization, timer channels, and peripheral ratings require confirmation from the manufacturer datasheet. Typical applications include industrial control modules, USB-connected data loggers, CAN-based equipment, motor and actuator controllers, communication interfaces, and compact consumer appliances. A design should use the manufacturer's pin, electrical-characteristic, clock, and application guidance to confirm every peripheral and signal. PCB design should provide a stable 3.3 V supply, decoupling close to the power pins, an appropriate oscillator network, and clean grounding for communication interfaces. The exposed 64-pin footprint also requires careful fan-out and signal-integrity review when used with fast external buses or long board routes. This page consolidates the verified distributor and manufacturer information, package-level alternatives, procurement details, and application-oriented design guidance. It also distinguishes explicitly verified specifications from parameters that still require confirmation from the official STM32F103R6T6ATR technical documentation.

It operates from 2.0 V to 3.6 V and provides 37 I/O ports for compact embedded-control designs. A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, volatile data memory, peripherals, and I/O on one device. The STM32F103 belongs to the STM32F1 performance-line family of 32-bit microcontrollers. Its ARM Cortex-M3 core combines a 32-bit instruction set with deterministic real-time control, while Flash retains programmed firmware without power and SRAM supports working data and stack operations. Key features include up to 72 MHz operation, single-cycle multiplication, USB and CAN connectivity, two ADCs, multiple communication interfaces, and a collection of timers. The verified device data identifies an operating performance of 90 DMIPS and 1.25 DMIPS/MHz. Its 32 KB Flash capacity is appropriate for compact control firmware, while the 10 KB SRAM allows modest buffering without requiring an external memory device. The STM32F103R6T7A integrates its timer, serial-communication, analog-conversion, and digital I/O resources around the Cortex-M3 core. This integration reduces board complexity in applications that need both real-time control and communications. USB and CAN provide useful paths for configuration, data exchange, and industrial networking, while the ADCs support analog sensor acquisition without separate converters. Typical uses include USB-connected control accessories, CAN-based industrial nodes, motor-control subsystems, sensor-acquisition equipment, compact automation controllers, and communication bridges. The 64-LQFP package is easier to inspect and rework than very fine-pitch packages, making it practical for prototypes, industrial controls, and moderately populated mixed-signal boards. Designers should verify the complete pin multiplexing, clock plan, decoupling requirements, and firmware support for every peripheral used. The 2.0 V to 3.6 V supply range also requires attention to input tolerance, output-driver loading, and the voltage levels of attached USB, CAN, and sensor interfaces. This product page consolidates verified distributor specifications, lifecycle information, package details, drop-in alternatives, comparison parameters, and practical design guidance. It also distinguishes verified facts from details that require confirmation in the manufacturer datasheet before production release.

STM32F103R8H6

STM32F103R8H6 - 72MHz Cortex-M3 64KB Flash MCU, 64-TFBGA | STMicroelectronics

The STMicroelectronics STM32F103R8H6 is an ARM Cortex-M3 32-bit RISC microcontroller operating at 72 MHz with 64 KB (64K x 8) of embedded Flash, delivered in a compact 64-TFBGA (5x5 mm) package. It belongs to the STM32F103 medium-density performance line and delivers 90 DMIPS (1.25 DMIPS/MHz) of compute in a surface-mount footprint smaller than a 10 mm x 10 mm LQFP. A microcontroller is a complete single-chip computer: an ARM Cortex-M3 CPU core, on-chip Flash program memory, SRAM data memory, and a rich set of peripherals - timers, ADCs, communication interfaces - integrated on one die. In the power management and embedded hierarchy, an MCU such as this sits above a bare CPU core and below a system-on-chip: the developer writes firmware in C, flashes it into the internal memory, and the silicon handles real-time acquisition, control and communications without external support chips. The STM32F103R8H6's headline features are a 72 MHz Cortex-M3 core with single-cycle multiplication and a Harvard-style three-cycle pipeline, plus a peripheral set that includes USB full-speed device support, a CAN bus controller, seven 16-bit timers, two 10-bit ADCs, and nine communication interfaces (USART, UART, SPI, I2C). Two 12-bit ADCs with a 1 Msps sample rate, four 16-bit timers with dead-time generation, and a full set of GPIO make it a compact but capable control node. Operationally the device runs from 2.5 V or 3.3 V supply rails, making it a natural fit for 3.3 V industrial and consumer boards as well as 5 V systems with local regulation. The 'H6' suffix identifies the 64-pin TFBGA package with industrial-grade temperature qualification, while the 64 KB of Flash supports bootloader plus application code in a single image. Typical deployments include industrial monitoring and metering nodes, USB-connected data acquisition and programming fixtures, CAN-based motor and HVAC control boards, smart-home sensor gateways, and IoT edge nodes that need a small, low-cost MCU with more compute than an 8-bit part. ST's STM32F1 ecosystem - HAL drivers, CubeMX code generation, and the STM32Cube programmer/debug toolchain - shortens bring-up time considerably. Designers should note that the 5x5 mm TFBGA-64 footprint is fine-pitch and requires an HDI-style PCB stack-up with laser-via fanout to route to a fine-pitch BGA escape layer; the alternative LQFP-64 members of the same family are easier to hand-assemble. Decoupling should place 100 nF ceramic capacitors at each supply pin plus bulk capacitance close to the device, and SWD/JTAG debug access must be brought out for production programming. This page consolidates distributor pricing, verified pin-compatible drop-in alternatives, and hands-on layout and firmware-migration guidance that the manufacturer datasheet alone does not present in one place, giving design-in teams a faster path from part selection to working prototype.

STM32F103R8H7

STM32F103R8H7 - 72MHz Cortex-M3 64KB MCU | STMicroelectronics

The STMicroelectronics STM32F103R8H7 is a 32-bit Arm Cortex-M3 microcontroller operating at 72 MHz, with 64 KB of Flash program memory and 51 I/O pins, packaged in a 64-TFBGA 5x5 mm module. The device belongs to STMicroelectronics' STM32F103 medium-density performance line and combines a high-performance RISC core with 12-bit ADCs, general-purpose and PWM timers, and serial interfaces including I²C and USART. Its specified operating temperature range is -40°C to 105°C. A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and I/O into one device. The STM32F103R8H7 is specifically an embedded microcontroller, a member of the Arm Cortex-M microcontroller family within the broader semiconductor and embedded-control hierarchy. Its combination of moderate Flash capacity, numerous I/O, and integrated analog and communications peripherals makes it suitable for compact control systems that require more processing capability than a basic 8-bit controller. Key features include an Arm Cortex-M3 core operating at 72 MHz, 64 KB of Flash memory, 51 I/O pins, and two 12-bit ADC channels according to the available product records. The peripheral set includes three general-purpose 16-bit timers plus one PWM timer, I²C, USART, Serial Wire Debug, JTAG, a CRC calculation unit, and a 96-bit unique ID. These integrated resources reduce the number of external components needed for embedded sensing, communications, and timing functions. The STM32F103 architecture uses a single-cycle 32-bit Arm Cortex-M3 RISC core. Its integrated flash stores the application firmware, while the peripheral arrangement supports simultaneous control, communication, and analog measurement tasks. Sleep, Stop, and Standby operating modes are identified in the available datasheet records, allowing firmware to balance responsiveness against power consumption in embedded designs. Typical applications include industrial control modules, motor-control and instrumentation equipment, communication-enabled embedded products, and compact automation controllers. The 51 available I/O support digital peripherals and external interfaces, while the 12-bit ADC supports analog measurement. For designs needing direct motor regulation, the timer and PWM resources provide suitable foundations for deterministic actuator control when configured with the appropriate firmware. The primary design consideration is package-specific PCB implementation. Because this orderable MPN uses a 64-TFBGA 5x5 mm package rather than the more common STM32F103R8T6 LQFP variant, PCB land patterns, assembly processes, and thermal design must match the TFBGA footprint exactly. Firmware compatibility does not by itself establish hardware interchangeability, so pin assignment and peripheral configuration should be reviewed against the selected package. This page consolidates the supplied manufacturer and distributor records, identifies the package-specific sourcing constraints, and separates directly relevant electrical facts from data still requiring confirmation. It also provides engineering-focused application guidance and an explicit explanation of why verified drop-in alternatives are limited for this uncommon TFBGA ordering code.

STM32F103R8T6

STM32F103R8T6 - 72MHz Cortex-M3, 64KB Flash MCU | STMicroelectronics

The STMicroelectronics STM32F103R8T6 is a medium-density performance-line 32-bit microcontroller with an ARM Cortex-M3 core running at 72 MHz, 64 KB of Flash memory and 20 KB of SRAM, housed in a 64-pin LQFP package (7 x 7 mm, 0.5 mm pitch). A microcontroller (MCU) integrates a processor core, memory, and peripherals on a single chip, sitting at the center of the embedded systems hierarchy: silicon -> ARM Cortex-M core -> STM32F1 family -> STM32F103 medium-density line. MCUs execute control, communication, and signal-processing tasks in everything from industrial machines to consumer appliances. Key features include the 72 MHz Cortex-M3 with Harvard architecture, two 12-bit ADCs with 1 us conversion time, and six timers (three general-purpose 16-bit timers plus one advanced PWM timer). Communication coverage is broad: USB 2.0 full-speed device, CAN 2.0B, two SPI, two I2C, and three USARTs, plus seven-channel DMA for data movement without CPU load. Architecturally, the Cortex-M3 provides a 3-stage pipeline, nested vectored interrupt controller (NVIC) with 43 maskable interrupt channels, and a Thumb-2 instruction set that reduces code size. The embedded Flash supports zero-wait-state execution up to 24 MHz with prefetch buffer performance at 72 MHz, while the AHB/APB bus matrix lets high-speed peripherals run independently of the core. Typical applications include industrial motor control (the advanced PWM timer with dead-time generation is purpose-built for this), USB and CAN-enabled communication nodes, and general-purpose embedded control in meters, printers, and building automation. Design consideration: keep VDD within the 2.0 V to 3.6 V range and decouple each VDD/VDDA pin with 100 nF ceramics close to the package; BOOT0 must be tied to a defined level for reliable boot from Flash.

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.

STM32F103RBT6 - 72MHz Cortex-M3 MCU 128KB Flash | ST

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.

STM32F103RBT6TR - 72MHz Cortex-M3, 128KB Flash MCU | STMicroelectronics

The STMicroelectronics STM32F103RBT6TR is a 32-bit ARM Cortex-M3 microcontroller running at 72 MHz (90 DMIPS, 1.25 DMIPS/MHz) with 128 KB Flash and 20 KB SRAM, housed in a 64-pin LQFP surface-mount package (Tape & Reel packaged, indicated by the TR suffix). A microcontroller (MCU) is a single-chip computer that integrates a processor core, program memory, data memory, and peripheral interfaces on one die. Within the embedded-systems hierarchy, the STM32F103RBT6TR belongs to the medium-density performance line of the STM32F1 family: MCU -> 32-bit MCU -> ARM Cortex-M3 MCU -> STM32F1 series -> STM32F103 medium-density performance line. Key features include two 12-bit ADCs with up to 10 external channels and 1 us conversion time, seven 16-bit timers, and nine communication interfaces: two I2C, three USARTs, two SPIs, a full-speed USB 2.0 device controller, and a CAN 2.0B controller. 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.

STMicroelectronics STM32F103RCY6CTR is a 32-bit ARM Cortex-M3 microcontroller with 256 KB of Flash memory in a 64-UFBGA/WLCSP package. The high-density STM32F103 device combines USB, CAN, 11 timers, 3 ADCs, and 13 communication interfaces for compact embedded-control, industrial automation, metering, motor-control, and connected-device designs. Its 64-lead wafer-level chip-scale package supports space-constrained boards requiring substantial peripheral integration without a large leaded footprint. An ARM Cortex-M3 microcontroller is a 32-bit embedded processor that combines a CPU core, memory, interrupt control, and peripherals on one integrated circuit. It belongs to the microcontroller hierarchy and executes firmware directly from embedded Flash.

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.

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 device also features a 7-channel DMA, an SDIO interface for SD/MMC cards, and a CRC engine for embedded communication stacks. Performance is rated up to 90 DMIPS at 72 MHz, with single-cycle multiply and hardware divide. Architecturally, the STM32F103RDT6 uses a multi-AHB bus matrix connecting the Cortex-M3 core, DMA engines, and on-chip peripherals, allowing simultaneous memory and peripheral access without contention. Standard peripherals include three general-purpose 16-bit timers, one PWM timer for motor control, two watchdog timers (independent and window), and a SysTick timer. Embedded Flash is zero-wait state up to 24 MHz; above that, a prefetch buffer maintains 72 MHz operation without software wait states. Typical applications include three-phase motor drives (BLDC, PMSM, induction), industrial control PLCs, USB-CAN bridges, HVAC controllers, low-cost data loggers, biometric instrumentation, and handheld POS equipment. The combination of CAN, USB, and 12-bit ADC resolution in a 64-LQFP package makes the STM32F103RDT6 especially common in automotive aftermarket and 24 V industrial designs where USB diagnostics and CAN fieldbus must coexist. Design consideration: At 72 MHz and 1.8 V core, idle current is roughly 27 mA; selecting sleep or stop modes with RTC wake-up can drop this to the tens-of-microamp range for battery-backed nodes. The 64-LQFP 10x10 mm footprint with 0.5 mm pitch can be hand-soldered, but a 4-layer PCB with continuous ground pour under the exposed pad is recommended for stable ADC performance.
