STM32F103RGT6 - 72MHz Cortex-M3 MCU 1MB Flash | STMicroelectronics

The STMicroelectronics STM32F103RGT6 is an XL-density performance line 32-bit microcontroller based on the ARM Cortex-M3 core running at up to 72 MHz (1.25 DMIPS/MHz), with 1 MB Flash memory and 96 KB SRAM, housed in a 64-pin LQFP (10x10 mm) package. A microcontroller (MCU) is a single-chip computer that integrates a processor core, memory, and programmable peripherals on one die, sitting within the broader hierarchy of semiconductor devices as an embedded processor within the system-on-chip and power management ecosystem. The STM32F1 series performance line targets cost-sensitive embedded control where the ARM Cortex-M3 architecture provides deterministic, single-cycle multiply and hardware division. Key features include 1 MB of embedded Flash for large application code, 96 KB of SRAM, 17 timers, 3x 12-bit ADCs, and 13 communication interfaces covering USB, CAN, USART, SPI, and I2C. The flexible static memory controller (FSMC) supports 4 chip selects and a parallel LCD interface in 8080/6800 modes. Architecturally, the Cortex-M3 core operates from a 2.0V to 3.6V supply with an embedded PLL generating the 72 MHz system clock. Interrupt latency is handled by the nested vectored interrupt controller, and the bus matrix enables parallel peripheral access for deterministic real-time behavior in motor control and communication workloads. Typical applications include industrial automation and motor control, USB and CAN-based communication modules, consumer appliances, and low-cost development platforms, where the large 1 MB Flash accommodates RTOS and communication stacks without external memory. Design consideration: the ADC performance is sensitive to VDDA quality, so provide separate analog supply filtering; also note Flash zero-wait-state behavior only up to 24 MHz, with wait states required at 72 MHz.

The ADC channels can monitor sensors, potentiometers, or analog process inputs where 12-bit resolution and conversion throughput are sufficient. PCB design should preserve clean supply distribution, ground continuity, analog-input routing, and exposed-pad or thermal-pad handling appropriate to the exact LQFP-48 land pattern. Firmware should also account for the difference between a 72 MHz maximum clock and lower operating frequencies during initialization, power management, and peripheral timing. This page consolidates verified source data, substitution limits, and engineering guidance rather than presenting unverified substitute parts as unconditional drop-ins.

It belongs to the STM32F1 medium-density performance line and integrates USB, CAN, two 12-bit ADCs, seven timers, PWM capability, and nine communication interfaces for compact embedded control designs. A microcontroller, or MCU, integrates a processor core, memory, peripherals, and interface circuitry on one semiconductor device. The STM32F103TB is an Arm Cortex-M3 RISC MCU within the STM32 family, combining general-purpose embedded processing with analog measurement, timing, serial communications, and motor-control resources. Its UFQFPN surface-mount package supports compact PCB layouts while retaining a substantial pin count for external memory, sensors, actuators, and communications. Principal features include a 72 MHz maximum operating frequency, 128 KB Flash, two 12-bit ADCs, three general-purpose 16-bit timers, an additional PWM timer, USB, CAN, and nine communication interfaces. These resources allow the STM32F103TBU6 to handle control loops, data acquisition, protocol bridging, and peripheral supervision without requiring separate logic devices. The 36-pin package provides access to the mixed-signal and communication resources required by embedded systems. The STM32F103TBU6 uses a 32-bit Arm Cortex-M3 RISC core and belongs to STMicroelectronics' medium-density performance line. Its combination of 128 KB Flash and 72 MHz operation provides useful headroom for protocol stacks and real-time control firmware.

Designers can use the two ADCs for analog inputs, the communication interfaces for host or network links, and the timers for precise periodic or PWM functions. The same 6 x 6 mm package also makes it suitable for space-constrained control modules where a smaller MCU with fewer pins would be insufficient. When laying out the PCB, place the MCU's decoupling capacitors and analog-supply components according to the manufacturer's reference layout, and route sensitive analog inputs away from fast digital and communication signals. Firmware should account for the 72 MHz clock, peripheral initialization sequence, and any external peripheral requirements. If GD32F103TBU6 is considered as a second source, validate clock wait states, Flash behavior, ADC characteristics, and peripheral differences in hardware. This page consolidates verified distributor pricing, manufacturer specifications, package information, strict same-package alternatives, and practical migration guidance. It also identifies missing datasheet details rather than estimating them, providing engineers with a source for initial design review, sourcing, and replacement planning.

STM32F103VBH7 - 72MHz Cortex-M3 MCU 128KB LFBGA-100 | STMicroelectronics

The STMicroelectronics STM32F103VBH7 is a 32-bit ARM Cortex-M3 microcontroller operating at 72 MHz with 128 KB of embedded Flash memory, packaged in a 100-ball LFBGA (10x10 mm). It integrates 1.25 DMIPS/MHz performance (90 DMIPS total), a single-cycle hardware multiplier and divider, and a rich peripheral set: two 12-bit ADCs (1 us conversion), seven 16-bit timers, USB Full-Speed, CAN 2.0B, two I2C, three SPI, two I2S, three USART, two UART, one SDIO, and an FSMC interface for external memory. The supply voltage is 2.0 V to 3.6 V and the device provides 80 general-purpose I/O pins with interrupt capability. An ARM Cortex-M3 microcontroller (often shortened to MCU or simply "Cortex-M3") is a 32-bit RISC processor designed by Arm that targets deterministic, real-time embedded applications. Within the broader taxonomy, it sits under MCU (microcontroller) -> embedded processor -> semiconductor IC. The Cortex-M3 family is widely used in industrial control, motor drives, consumer electronics, and USB peripherals because it combines deterministic interrupt latency (typically 12 cycles) with low power consumption and a Thumb-2 instruction set that keeps code density comparable to 8-bit MCUs. STMicroelectronics' STM32F103 sub-family further extends this with the high-speed peripherals listed above. Key features of the STM32F103VBH7 include support for Sleep, Stop, and Standby low-power modes, an internal 8 MHz RC oscillator with PLL multipliers up to 9x (yielding 72 MHz), an embedded real-time clock (RTC) with calendar and alarm functions, and a 96-bit unique device ID. The two 12-bit ADCs each offer up to 16 input channels (12 on the LFBGA-100 package variant) and can be triggered by timers for precise sampling in motor-control loops. The USB Full-Speed device interface requires an external 1.5 k pull-up and integrates a dedicated 48 MHz PLL. Architecturally, the STM32F103VBH7 uses a multi-AHB bus matrix that allows the DMA controller, CPU, and peripherals to operate in parallel without contention. The NVIC (Nested Vectored Interrupt Controller) accepts up to 43 maskable interrupt sources with 16 priority levels, enabling deterministic response time for time-critical applications such as USB isochronous transfers and motor PWM. A 7-channel DMA controller supports peripherals including the ADCs, SPIs, I2Cs, USARTs, and timers, offloading memory copies from the CPU and improving throughput. Typical applications include industrial motor control (BLDC, PMSM, and stepper drivers), USB HID peripherals (mice, keyboards, custom input devices), CAN-bus nodes for vehicle and industrial networks, point-of-sale terminals, and HVAC controllers. The 72 MHz speed and USB+CAN combination make it a frequent choice for gateways and protocol converters bridging CAN and USB or CAN and Ethernet-via-SPI. When designing with the LFBGA-100 package, ensure 4-layer PCB stack-up with controlled-impedance routing for USB DP/DM, since the 90-ohm differential pair must meet USB 2.0 Full-Speed signalling. Decouple each VDD/VSS pair with a 100 nF X7R ceramic placed within 3 mm of the ball, and add a 4.7 uF bulk capacitor near the regulator input. Configure unused I/O as analog inputs (high-impedance) to minimize quiescent current in Stop mode.

Verified product features include a 72 MHz CPU, 128 KB of Flash, seven timers, two ADCs, nine communication interfaces, USB support, and CAN support. Its 100-pin UFBGA package allows access to a large pin count without the lead span of a conventional 100-pin through-hole or LQFP package. The 7 x 7 mm land pattern is intended for high-density PCB layouts, but exposed-pad routing, assembly capability, and thermal performance must be evaluated against the complete manufacturer documentation. The STM32F103VBI6 uses the Arm Cortex-M3 architecture with a 32-bit instruction set. Its 128 KB Flash provides on-chip program storage, while the peripheral mix supports common embedded-control tasks such as digital I/O, timing, analog measurement, serial communications, USB, and CAN. Exact SRAM capacity, ADC resolution, I/O voltage limits, timer channels, and electrical characteristics are not present in the supplied search data and therefore remain [DATA_NEEDED: SRAM capacity], [DATA_NEEDED: ADC resolution], and [DATA_NEEDED: detailed electrical characteristics]. Typical uses include industrial controllers, USB-connected embedded products, CAN network nodes, data-acquisition equipment, motor-control subsystems, and compact control boards. The seven timers and two ADCs make it relevant to systems combining periodic control functions with analog input conditioning. USB and CAN connectivity can reduce external interface hardware when the board already uses the STM32F1 ecosystem, although firmware, clocking, peripheral-equivalence, and qualification checks remain essential before redesigning an existing product. The principal design consideration is that the 100-UFBGA package demands fine-pitch PCB layout and careful assembly planning. A manufacturer-qualified pin map was not included in the supplied data, so engineers must verify all 100 terminals, exposed-pad requirements, recommended decoupling, and test-point access in the official STM32F103 documentation before schematic capture or PCB release. Pricing also was not exposed in the supplied results, making procurement cost and lifecycle planning dependent on a current distributor quotation. This product record consolidates the verified STM32F103VBI6 specifications, distributor availability, package information, interface features, sourcing links, and engineering caveats into one decision aid. It distinguishes documented facts from missing parameters and avoids presenting functional MCU alternatives as verified drop-in replacements, which is important because package, pin mapping, clock configuration, and peripheral compatibility must be confirmed independently.

This product record consolidates the verified STM32F103VBI6TR specifications, distributor availability, package information, interface features, sourcing links, and engineering caveats into one decision aid. It distinguishes documented facts from missing parameters and avoids presenting functional MCU alternatives as verified drop-in replacements, which is important because package, pin mapping, clock configuration, and peripheral compatibility must be confirmed independently.

STM32F103VBT6 - 72MHz Cortex-M3 MCU 128KB Flash LQFP-100 | ST

The STMicroelectronics STM32F103VBT6 is a 32-bit medium-density performance line ARM Cortex-M3 microcontroller running at 72 MHz with 128 KB Flash and 20 KB SRAM, housed in a 100-pin LQFP (14x14 mm) package. A microcontroller (MCU) is a single-chip computer that integrates a processor core, memory, and peripherals on one die, forming the lowest level of the embedded systems hierarchy: MCU -> microcontroller -> embedded processor -> semiconductor device. The STM32F1 series is built on the ARM Cortex-M3 architecture, which delivers 90 DMIPS at 1.25 DMIPS/MHz with single-cycle multiply and hardware division, making it one of the most widely adopted 32-bit MCU platforms in industrial and consumer electronics. Key features of the STM32F103VBT6 include seven timers (three general-purpose 16-bit timers plus one advanced PWM motor-control timer), two 12-bit ADCs with up to 16 external channels, and nine communication interfaces: five USART/UARTs, two I2C, two SPI, plus USB 2.0 full-speed device and CAN 2.0B. The 43-maskable interrupt nested vectored interrupt controller enables deterministic real-time response. Technically, the device operates from a 2.0 V to 3.6 V supply with a robust power architecture including POR/PDR, programmable voltage detector, and low-power run, sleep, stop, and standby modes. The Flash accelerator allows the CPU to achieve near zero-wait-state execution at 72 MHz. DMA controller support offloads data transfers between peripherals and memory. Typical applications include industrial motor control, PLC I/O modules, communication gateways using USB or CAN, medical handheld instruments, and consumer appliances. The combination of a PWM motor-control timer and dual ADC makes it a classic choice for three-phase inverter control. For design, note that GPIO output drive and 5 V tolerance rules differ per pin group; consult the datasheet pin definition table before connecting 5 V logic. Decouple VDD/VDDA pins with 100 nF ceramics placed close to each supply pair.
