STM32F103C6T7ATR

STM32F103C6T7ATR - 32-Bit 72MHz Cortex-M3 MCU | STMicroelectronics (Tape & Reel)

The STMicroelectronics STM32F103C6T7ATR is a 32-bit ARM Cortex-M3 RISC microcontroller operating at 72 MHz, with 32 KB of Flash memory, 10 KB of SRAM, and a 48-LQFP 7 x 7 mm package. It operates from a 2.5 V or 3.3 V supply and belongs to the STM32F103 low-density performance-line family. The combination of a 72 MHz Cortex-M3 core, compact 48-pin surface-mount package, and 32 KB embedded Flash makes the device suitable for compact embedded control, sensing, communications, and actuator-management systems. A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripheral interfaces, and control logic on one IC. In the STM32 hierarchy, the STM32F103C6T7ATR is an ARM Cortex-M3 microcontroller, a 32-bit RISC controller within the STM32F1 family and the broader embedded microcontroller and semiconductor categories. Its low-density designation indicates a balance between processing capability, memory capacity, package size, and cost rather than the resources associated with the largest STM32F1 devices. The verified configuration provides a maximum core frequency of 72 MHz and 32 KB of Flash organized as 32K x 8. The device also includes 10 KB of SRAM. Its 48-LQFP package exposes 48 pins on a 7 x 7 mm body and is suitable for automated assembly and access to the family’s communication and control peripherals. The 2.5 V and 3.3 V operating options support conventional industrial and embedded system rails, while the manufacturer identifies the part as an ARM Cortex-M3 performance-line MCU. The STM32F103 architecture uses a 32-bit ARM Cortex-M3 RISC core. Compared with an 8-bit microcontroller, the 32-bit instruction set and 72 MHz operating point provide greater arithmetic and control throughput for protocols, state machines, and real-time tasks. Memory remains the principal system constraint: the 32 KB Flash footprint can hold the application firmware, while the 10 KB SRAM provides working memory for stacks, buffers, and control data. Typical uses include industrial sensor nodes, compact motor-control and actuator boards, embedded communication equipment, measurement instruments, and general-purpose industrial control modules. The 48-pin LQFP provides more exposed connections than a small-outline package while retaining a manageable board area. These applications must be reviewed against the manufacturer datasheet for the exact peripheral mix, pin multiplexing, clock configuration, electrical limits, and startup requirements. A primary design consideration is firmware and ecosystem continuity. Designs should reserve the required programming and debug connections, validate all 48 pin assignments against the datasheet, and confirm that the 32 KB Flash and 10 KB SRAM budgets remain adequate. Because the exact peripheral and pin functions are not included in the supplied verified excerpts, they must not be inferred from other STM32F103 members. This page consolidates the verified manufacturer and distributor identity, memory and clock data, package information, pricing, drop-in sourcing considerations, and application guidance into a focused engineering record. It also distinguishes directly supported specifications from information that still requires confirmation from the manufacturer datasheet.

The device belongs to the STM32F103 low-density performance line and combines a 2.5 V/3.3 V operating supply with USB, CAN, ADC, timer, and serial-interface resources for compact embedded systems. A microcontroller is an integrated circuit containing a processor core, memory, and programmable peripherals on one semiconductor die. Within the product hierarchy, the STM32F103C6U6A is a Cortex-M3 microcontroller, part of the ARM-based STM32 family, and falls within the broader embedded semiconductor category. Its low-density configuration is intended for control-intensive products that need more processing capability than an 8-bit MCU without moving to a higher-pin-count STM32 device. Key features include a maximum 72 MHz core frequency, 32 KB Flash, 37 I/O ports, two 12-bit ADCs, USB, CAN, six timers, and six communication interfaces. According to the STMicroelectronics STM32F103x4 and STM32F103x6 family documentation, the Cortex-M3 core provides 1.25 DMIPS/MHz. These resources support motor and industrial control, communications gateways, USB peripherals, sensor acquisition, and compact consumer equipment. The STM32F103C6U6A architecture combines a 32-bit RISC processor with dedicated peripheral blocks for analog measurement, serial communications, timing, and control. Its performance-line positioning provides substantially more processing throughput than simple 8-bit microcontrollers, while the 48-pin VFQFPN format supports compact PCB layouts. The exposed pad provides an additional thermal and electrical connection to the board when the package is assembled correctly. Typical applications include USB-connected data loggers, CAN-based industrial nodes, sensor interface controllers, motor-control auxiliaries, communication equipment, and compact embedded control modules. Designers should confirm the exact peripheral mix, clock configuration, pin multiplexing, and exposed-pad layout against the official datasheet before releasing a PCB or transferring firmware. The principal design consideration is ensuring that the 2.5 V/3.3 V supply remains within the device limits while high-speed peripherals and analog circuitry are active. Place the required decoupling capacitors close to the power and ground pins, keep sensitive analog routing away from fast switching nodes, and connect the exposed thermal pad using the manufacturer-recommended land pattern and assembly process. This page consolidates verified manufacturer and distributor information, a structured comparison with candidate replacements, and practical design guidance. It is intended to help engineers identify whether the STM32F103C6U6A matches their memory, clock, package, peripheral, and sourcing requirements without treating merely similar microcontrollers as automatic drop-in replacements.

The STMicroelectronics STM32F103C8T6 is a 32-bit ARM Cortex-M3 medium-density performance-line microcontroller operating at up to 72 MHz, with 64 KB Flash and 20 KB SRAM, housed in a 48-pin LQFP package (7x7 mm). An ARM Cortex-M3 microcontroller (MCU) is a 32-bit RISC processor core designed by Arm Holdings for embedded applications requiring deterministic real-time performance at low power. The Cortex-M3 sits at the lower end of the Cortex-M family (above Cortex-M0/M0+ and below Cortex-M4/M7), and microcontrollers in this category combine the processor core with on-chip memory, peripherals, and analog blocks into a single system-on-chip. The STM32F103 family specifically belongs to the broader hierarchy: ARM Cortex-M3 -> 32-bit MCU -> STM32F1 series -> STM32 mainstream family -> STMicroelectronics microcontrollers -> semiconductor. This hierarchy matters because it determines the toolchain (Arm Cortex-M3 supports the standard Arm Keil, IAR, GCC, and STM32CubeIDE flows) and the peripheral programming model used across the STM32 platform. Key features include 64 KB of embedded Flash with read-while-write capability, 20 KB of SRAM, a 2.0 V to 3.6 V supply range, an 8 MHz internal RC oscillator with PLL multiplier to 72 MHz, two 12-bit ADCs (1 µs conversion, up to 16 channels), seven 16-bit timers, and a full-speed USB 2.0 Full-Speed device/host/OTG controller. Communication peripherals include three USARTs, two SPIs (18 Mbit/s), two I2C buses (400 kHz), one CAN 2.0B interface, and one USB Full-Speed port. The 48-pin LQFP package exposes 37 GPIO pins tolerant to 5 V. Architecturally, the Cortex-M3 core delivers 1.25 Dhrystone MIPS per MHz, supports the Thumb-2 instruction set, and includes a Nested Vectored Interrupt Controller (NVIC) with configurable priority and hardware stack handling. The integrated voltage regulator and brown-out reset (BOR) simplify power design, while the 4-byte backup register with a tamper-detection pin supports battery-backed RTC modes. Typical applications include industrial control boards, motor drives (BLDC/PMSM FOC complements), USB HID/COM port devices, CAN-bus node interfaces, and low-cost development platforms such as the well-known "Blue Pill" board. When designing with this device, place a 100 nF ceramic decoupling capacitor as close as possible to each VDD/VDDA pin pair, and reserve the NRST pin connection for a 10 kΩ pull-up and optional reset button. Ensure the BOOT0 pin state matches the desired boot memory on every power-up.

It integrates USB 2.0 Full-Speed, CAN 2.0B, seven 16-bit timers, two 12-bit ADCs (up to 1 MSPS), and nine communication interfaces (I2C, SPI, USART, USB, CAN) on a single die, delivering 90 DMIPS at 1.25 DMIPS/MHz. An ARM Cortex-M3 microcontroller is a 32-bit RISC processor core designed for deterministic real-time embedded control, sitting within a broader taxonomy of MCU -> embedded processor -> microcontroller -> semiconductor. 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.

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.

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.

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 - 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 - 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. This page synthesizes distributor pricing, seven drop-in alternatives including GigaDevice GD32F103, and practical design notes not found in the standard datasheet.
