STM32F102R6T6A

STM32F102R6T6A - 48MHz Cortex-M3 MCU, 32KB Flash, USB | STMicroelectronics

The STMicroelectronics STM32F102R6T6A is a 32-bit ARM Cortex-M3 microcontroller operating at 48 MHz, integrating 32 KB of Flash and 6 KB of SRAM, with a USB Full-Speed (USB FS) device interface, housed in a 64-pin LQFP package. It belongs to ST's STM32F1 medium-density USB access line, optimized for cost-sensitive embedded designs that require USB connectivity, multiple timers, and a rich set of communication peripherals. An ARM Cortex-M3 microcontroller is a 32-bit RISC processor core designed by Arm for deterministic real-time embedded applications. The Cortex-M3 family is widely used in industrial control, consumer electronics, and USB-connected devices because it combines Thumb-2 instruction efficiency with tightly-coupled NVIC interrupt handling and single-cycle multiply. Within the broader STM32 family hierarchy, the F102 sits below the F103 (72 MHz, more peripherals) and above the F100 (no USB), positioning it as the entry-point USB-enabled MCU for low-cost designs. Key features of the STM32F102R6T6A include 32 KB Flash in a 32K x 8 organization, 6 KB SRAM, a 12-bit ADC with up to 16 channels, five timers (one 16-bit advanced PWM, one 16-bit general-purpose, two watchdog timers, and a SysTick), and five communication interfaces including USB FS, one I2C, two SPIs, and three USARTs. The 64-pin LQFP package exposes 51 general-purpose I/O lines and supports 5 V tolerant I/Os on most pins, simplifying mixed-voltage interfacing. The device operates from a 2.0 V to 3.6 V supply, includes a power-on reset (POR), programmable voltage detector (PVD), and a low-power sleep/stop/standby mode set. The integrated USB 2.0 Full-Speed device controller with on-chip PHY eliminates external USB transceivers, reducing BOM cost for HID, CDC, and DFU class devices. Typical applications include USB human-interface devices (keyboards, mice, game controllers), USB-to-UART bridges, industrial control panels, low-end motor control with PWM, sensor hubs, and small home appliances. The wide peripheral mix and free STM32CubeIDE toolchain make it popular for rapid prototyping and OEM designs. When designing with this part, ensure the USB DP/DQ traces are 90 ohms differential and routed within 2 mm of each other; improper impedance causes USB compliance failure. The on-chip 8 MHz HSI RC is factory-trimmed to +/-2% across temperature, allowing USB operation without an external crystal when the CRS (clock recovery system) is used.

STMicroelectronics STM32F103C4T6A is a 32-bit ARM Cortex-M3 microcontroller rated up to 72 MHz, with 16 KB of Flash memory and 37 I/O ports, packaged in a 7 x 7 mm LQFP-48. The device operates from a 2.4 V to 3.6 V supply and includes single-cycle multiplication, hardware division, and 1.25 DMIPS/MHz performance at zero wait-state memory access. A microcontroller is a programmable control component that integrates a processor core, memory, peripheral interfaces, and I/O in one device. The STM32F103C4T6A belongs to the STM32F1 performance-line family, where STM32 identifies the product family, F103 identifies the performance-line device series, and C4T6A identifies the specific memory, package, temperature, and ordering configuration. The principal features include a 72 MHz ARM 32-bit Cortex-M3 RISC core, 16 KB Flash, and 37 I/O ports. Its operating voltage range of 2.4 V to 3.6 V suits conventional 3.3 V embedded systems. The Cortex-M3 core supports single-cycle multiplication and hardware division, helping reduce instruction count in control, communications, and signal-processing firmware. This ordering code belongs to the low- and medium-density STM32F1 platform, whose product family provides 12 timers, ADC and DAC resources, and up to eight communication interfaces according to the family-level product information. The 16 KB Flash capacity should be checked carefully against bootloader, application, and firmware-update requirements before design release because the smaller-memory variant may not accept code built for the 64 KB or 128 KB members. Typical applications include compact industrial controllers, sensor nodes, communication modules, motor-control peripherals, and educational embedded platforms. Its 48-lead LQFP package exposes more I/O and peripheral connections than smaller packages, while its 7 x 7 mm body keeps the component practical for multilayer PCB designs. A principal design consideration is memory planning. Engineers should reserve space for a bootloader, application code, configuration data, and future growth before fixing the firmware layout. Clock, low-power behavior, analog peripheral accuracy, and communication timing should be validated in hardware because only the explicitly verified family-level parameters are summarized in the supplied data. This product record combines verified manufacturer and distributor information with practical selection guidance, package-aware alternatives, and engineering design notes. It also distinguishes electrically similar alternatives from fully qualified drop-in choices by documenting memory, clock, software, and qualification differences that require review before substitution.

Supply voltage spans 2.0 V to 3.6 V with the core at 3.3 V nominal. Architecturally, the Cortex-M3 uses a 3-stage pipeline with Harvard bus structure, Thumb-2 instruction set, and a nested vectored interrupt controller (NVIC) delivering low, deterministic interrupt latency. Peripherals connect through the APB1/APB2 bus matrix, and the flash accelerator keeps 72 MHz execution efficient from zero-wait-state-capable memory ranges. Typical applications include motor control, industrial automation nodes, USB and CAN communication boards, consumer appliances, and low-cost development platforms such as the Blue Pill board ecosystem. For design, plan flash headroom carefully: 32 KB fills quickly with USB stacks or RTOS code, so consider the pin-compatible STM32F103C8T6 (64 KB) if code size is uncertain.

Cortex-M3 cores specifically target low-latency interrupt response (typically 12 clock cycles), Thumb-2 instruction efficiency, and hardware divide in a small footprint, making them the workhorse of industrial motor control, USB peripherals, and consumer device controllers where deterministic behavior matters more than raw clock speed. Key features include 72 MHz CPU with hardware single-cycle multiply, 64 KB Flash with read-while-write support, 20 KB SRAM, a 12-bit ADC with up to 10 channels, two I2C, two SPI, three USART, one USB Full-Speed, and one CAN 2.0B interface. Operating voltage spans 2.0V to 3.6V with internal 8 MHz and 40 kHz RC oscillators plus a PLL multiplying up to 72 MHz. The architecture pairs the Cortex-M3 core with a Nested Vectored Interrupt Controller (NVIC) supporting up to 43 maskable interrupts, a DMA controller with seven channels, and a power management block offering Sleep, Stop, and Standby modes. The bus matrix arbitrates between the core, DMA, and peripherals to keep deterministic throughput even when USB or CAN packets arrive. Typical applications include USB HID peripherals, industrial CAN-bus nodes, motor-control boards, low-cost development platforms (the 'Blue Pill' form factor), and consumer device controllers. The integrated USB PHY and CAN 2.0B controller make it particularly suited for bridging PC and industrial networks without external transceiver logic. Operating temperature spans -40C to +105C for the industrial grade. When designing with this device, watch the 2.0V minimum VDD during PLL start-up and ensure decoupling comprises a 100 nF X7R per VDD pin plus a bulk 4.7 uF tantalum or ceramic. The NRST pin requires an external 10 kohm pull-up and a 100 nF capacitor to VDD for reliable reset.

STM32F103CBT6 - 72MHz Cortex-M3 128KB Flash MCU | STMicroelectronics

The STMicroelectronics STM32F103CBT6 is a 32-bit ARM Cortex-M3 mainstream microcontroller running at up to 72 MHz with 128 KB of Flash and 20 KB of SRAM, packaged in a 48-pin LQFP (7x7 mm) device. What is a microcontroller? An MCU integrates a processor core, on-chip non-volatile memory (Flash), volatile working memory (SRAM), and a set of programmable peripherals onto a single silicon die. Within the embedded-computing hierarchy it sits above a bare microprocessor and below a full system-on-chip, and within ST's own portfolio the STM32F1 mainstream series places the STM32F103CBT6 between the ultra-low-power STM32L family and the higher-performance Cortex-M4 STM32F4 family. The part belongs to the medium-density STM32F103xx performance line, which targets cost-sensitive industrial and consumer control. Key features include a 72 MHz Cortex-M3 core with single-cycle hardware multiply and divide, a 2.0 V to 3.6 V supply range, an embedded nested vectored interrupt controller with 43 maskable channels, and up to 37 GPIO pins tolerant to 5 V. On-board communication is broad for the class: three USARTs, two I2C buses, two SPI interfaces, one full-speed USB 2.0 device port, and one CAN 2.0B active controller. Two 12-bit ADCs (1 us conversion), one 12-bit DAC, three general-purpose 16-bit timers, one PWM timer, and one basic timer give ample motor-control flexibility. Technically, the clock tree uses an internal 8 MHz RC oscillator plus a 4-16 MHz external crystal and a dedicated 32 kHz RTC oscillator; PLL multiplication reaches 72 MHz. Programming is via SWD or JTAG, with a built-in bootloader selectable via BOOT0/BOOT1. The 7x7 mm LQFP-48 package gives a low-cost, easy-to-assemble footprint suitable for both hand-soldered prototypes and high-volume SMT lines. Typical applications include industrial control nodes, motor drives, USB-to-CAN fieldbus bridges, medical instruments, smart-home hubs, and IoT gateways, where the combination of USB, CAN, and multiple UARTs positions the part as a communication-rich embedded hub. For design, decouple every VDD pin with 100 nF ceramics plus a single 4.7 uF bulk, place the HSE crystal traces short and guarded, and tie BOOT0 to GND for normal Flash boot or to VDD for system-memory bootloader.

These values make the device appropriate for industrial controllers, communication modules, motor-control peripherals, instrument interfaces, and embedded automation products. The LQFP package also provides a practical surface-mount format for prototypes and medium-density production assemblies. The STM32F103CBT7 is a programmable embedded platform rather than a fixed-function controller. Firmware determines the behavior of its GPIO, timers, serial interfaces, analog functions, and interrupt-driven control loops. Designers should therefore validate the complete peripheral configuration, clock plan, memory usage, and board-level power requirements against the applicable STMicroelectronics documentation before production release. Typical applications include connected industrial sensors, compact motor-control boards, USB or UART communication modules, data acquisition equipment, and embedded controller platforms. The 72MHz Cortex-M3 core provides processing headroom for control tasks, while 128KB flash provides room for application code and bootloader logic. The 48-LQFP package remains useful where a moderate pin count and easy visual inspection are preferred over a very small package. When designing around STM32F103CBT7, preserve the required decoupling and oscillator layout recommended by the manufacturer documentation, and confirm the exact peripheral pin mapping for the selected board. Do not assume that a competitor with a similar package name is electrically or firmware compatible without checking pin functions, voltage limits, clock behavior, and peripheral differences. This page combines verified distributor data with clearly marked data gaps rather than estimating missing electrical details.

The STMicroelectronics STM32F103R4H6A is a 32-bit ARM Cortex-M3 microcontroller operating at up to 72 MHz, with 16 KB of Flash memory and 64-pin TFBGA packaging in a 5 x 5 mm footprint. It combines a 2.0 V to 3.6 V supply range with 37 I/O ports and belongs to the STM32F103 low-density performance line. The device is positioned for compact embedded-control systems requiring USB, CAN, timers, analog conversion, and multiple communication interfaces without the memory footprint of a high-density STM32 design. A microcontroller is an integrated circuit that combines a processor core, memory, peripherals, and I/O in one device. The ARM Cortex-M3 core provides deterministic embedded processing, while the STM32F103 family adds timers, communication interfaces, analog converters, and GPIO resources. In the product hierarchy, this component is an MCU, a semiconductor, and a member of the STM32F1 low-density performance line. Key features include a maximum CPU frequency of 72 MHz, 16 KB of Flash, and 37 I/O ports. The verified product listing also identifies USB, CAN, six timers, two ADCs, and six communication interfaces within the applicable STM32F103 low-density family. These resources support USB-connected peripherals, CAN-based industrial or automotive communication, periodic control functions, and analog sensor acquisition. A separate source identifies a 2 V to 3.6 V supply range and RoHS-compliant construction, although exact operating-temperature and electrical-limit details were not included in the supplied data. The Cortex-M3 architecture supports 32-bit instruction execution and efficient embedded control without an external memory interface being required for the stated 16 KB configuration. Its peripherals reduce the need for discrete interface components in designs that combine data acquisition, communications, and control functions. Package density also makes the 5 x 5 mm TFBGA useful for compact modules and densely populated industrial controllers, although it requires careful PCB layout and inspection because its leads are hidden beneath the package. Typical uses include USB data acquisition equipment, CAN-connected industrial controls, motor-control subsystems, communication adapters, and compact embedded-control modules. The STM32F103R4H6A is especially appropriate when a design needs several peripherals but only 16 KB of application Flash. Developers should confirm that code size, firmware requirements, peripheral configuration, and production availability remain within the device's limits before final release. A primary design consideration is BGA assembly. Its pads require via-in-pad or fanout-capable PCB construction, adequate solder-paste control, X-ray inspection, and careful power-and-ground plane design. Decoupling should be placed directly at the appropriate supply pins, while signal routing must preserve USB, CAN, clock, and analog-input signal integrity. Confirming the exact pinout against the manufacturer datasheet is mandatory because the supplied sources do not provide the complete numbered 64-pin assignment. This page consolidates verified distributor and manufacturer information, strict same-package replacement candidates, application guidance, and practical PCB considerations. It distinguishes confirmed parameters from values that still require datasheet confirmation so engineers can make sourcing and design decisions without unsupported assumptions.

The device belongs to the STM32F103 performance-line family and combines a 2 V to 3.6 V supply range with 37 I/O ports, two ADCs, and multiple communication peripherals. An ARM Cortex-M3 microcontroller is a 32-bit RISC embedded processor designed for control-oriented products. In the product hierarchy, the STM32F103R6H6A is a microcontroller, semiconductor, and programmable control component. It executes firmware from embedded Flash while using peripherals for digital interfaces, analog measurement, timers, communications, and general-purpose input/output, making it suitable for compact industrial, communications, and consumer-control designs. The principal performance figures are a 72 MHz maximum core frequency, 90 DMIPS processing capability, 32 KB of Flash, and 37 I/O ports. The MCU also provides USB and CAN interfaces, two ADCs, and a timer set described in the available product information. These resources allow one device to coordinate data acquisition, protocol handling, timing, and actuator or digital-output control without requiring several separate interface ICs. The STM32F103R6H6A uses a single-cycle ARM Cortex-M3 core architecture with embedded high-speed memory and an extended I/O set. Its 64-TFBGA package measures 5 x 5 mm and uses a 0.5 mm pitch according to the available package description. The small land pattern supports compact assemblies, but its fine pitch and exposed thermal and routing requirements make careful PCB layout, via placement, and assembly-process verification important. Typical applications include USB-connected data-acquisition equipment, CAN-connected industrial controllers, compact motor-control systems, sensor-hub products, and low-cost embedded control boards. The 37 I/O ports support discrete digital interfaces, while the two ADCs suit analog sensor conditioning and the CAN and USB interfaces support connected equipment. A specific firmware design should confirm interrupt allocation, peripheral multiplexing, and communication bandwidth before release. Designers should verify the 2 V to 3.6 V operating range, clock configuration, flash wait-state requirements, decoupling, and exposed-pad thermal layout against the manufacturer datasheet. The verified distributor information does not provide the complete 64-pin assignment, so no pinout should be inferred solely from the package name. Prototype firmware should also be tested for peripheral conflicts and USB or CAN bus timing. This product record combines verified manufacturer and distributor specifications, current pricing as of 2026-10-30, package information, and practical design guidance. It distinguishes verified drop-in alternatives from package variants and flags parameters that remain unavailable instead of presenting guessed electrical or pin-level data as fact.

It combines 37 I/O ports, a 12-bit ADC, and 2 V to 3.6 V supply operation in a compact 7 mm by 7 mm surface-mount package. A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and interface circuitry on one IC. The STM32F103 is an ARM Cortex-M3 real-time microcontroller within the STM32 embedded product family. It is designed for control-oriented systems requiring deterministic peripheral access, modest onboard memory, and communication interfaces without a separate processor, memory, and interface devices. Key features include 72 MHz Cortex-M3 execution, 32 KB (32K x 8) Flash, 6 KB of SRAM, a 12-bit ADC, USB, CAN, seven 16-bit timers, and communication peripherals. The 37 I/O ports provide interfaces for sensors, actuators, communications, and human-machine input. Its 2 V to 3.6 V operating range suits conventional 3.3 V embedded equipment. Technically, the STM32F103R6T6 uses a 32-bit ARM Cortex-M3 RISC core and belongs to STMicroelectronics' low-density performance line. The part combines control processing and multiple communication peripherals in one device, reducing board area and component count. Its 32 KB Flash provides room for boot code, application firmware, and configuration data, while 6 KB of SRAM supports working state, buffers, and peripheral data handling. Typical applications include USB-connected data acquisition, CAN-based industrial or vehicle modules, motor and motion control, instrument panels, building automation controllers, and compact embedded control boards. The combination of USB, CAN, ADC channels, timers, and GPIO supports designs that gather analog measurements and communicate with a host or distributed controller network. Designers should verify clock configuration, pin multiplexing, USB and CAN transceiver requirements, and peripheral assignments against the STM32F103x4 and STM32F103x6 datasheet. The MCU does not include off-chip USB or CAN transceivers, so those interfaces still require suitable external circuitry. PCB design must also account for the 48-pin land pattern, 0.5 mm pitch, power decoupling, and exposed thermal requirements stated by the manufacturer. This page consolidates distributor specifications, manufacturer documentation, compatible-source options, comparison data, and practical integration guidance. It distinguishes documented drop-in candidates from merely similar devices, helping engineers evaluate the STM32F103R6T6 without relying on an incomplete distributor specification summary.

STM32F103R6T6A - 72MHz 32-bit MCU | STMicroelectronics

The STMicroelectronics STM32F103R6T6A 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 STM32F103R6T6A 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 STM32F103R6T6A technical documentation.
