STM32F103VBI6TR - 72MHz Cortex-M3 128KB MCU | STMicroelectronics (Tape & Reel)
料号： STM32F103VBI6TR ✗ 停产STM32F103VBI6TR 概述
A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, working memory, peripherals, and interface logic on one device. The STM32F103 series combines an Arm Cortex-M3 core with dedicated timers, analog converters, communication interfaces, and general-purpose I/O. Within the product hierarchy, the STM32F103VBI6TR is an Arm Cortex-M3 MCU, an embedded microcontroller, and a semiconductor designed for real-time embedded-control applications.
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 STM32F103VBI6TR 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 , , and .
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 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.

典型应用
STM32F103VBI6TR 适用于 6 应用s: USB-Connected Embedded Control, CAN Network Sensor Node, Industrial Data Acquisition, Motor and Motion Control, Compact HMI Controller, Programmable Logic Controller.
USB-Connected Embedded Control
The STM32F103VBI6TR fits compact USB control nodes because the verified specification lists USB support, a 72 MHz Arm Cortex-M3 core, and 128 KB of Flash alongside seven timers and two ADCs. A production design can place the MCU near a USB connector and use its integrated interface to reduce external controller demand. The 100-UFBGA, 7 x 7 mm package also helps conserve board area in compact instruments. Designers must still verify the exact USB pins, transceiver requirements, clock configuration, power sequencing, and device support using the official documentation. USB bus layout, impedance control, ESD protection, and firmware enumeration remain board-level responsibilities rather than automatic functions of the MCU.
推荐
CAN Network Sensor Node
The STM32F103VBI6TR is suitable for a CAN-connected sensor node because the verified feature set explicitly includes CAN, two ADCs, seven timers, nine communication interfaces, and a 72 MHz Cortex-M3 core. Two ADCs can support analog measurement channels, while timers can organize sampling, communication, and control tasks. The device should sit behind a qualified CAN transceiver, with bus termination, surge protection, common-mode handling, and grounding implemented separately on the PCB. Before schematic release, engineers must confirm CAN pin availability, timing constraints, buffer configuration, error handling, and firmware support from the manufacturer materials. Firmware-level conformance and production test coverage are as important as nominal protocol support.
推荐
Industrial Data Acquisition
The STM32F103VBI6TR can serve as the control core in a compact industrial data-acquisition module because its verified specification provides two ADCs, seven timers, nine communication interfaces, 128 KB of Flash, and a 72 MHz processor. The two ADC channels can sample sensor or control signals, while timers support periodic acquisition and conversion sequencing. Communications can connect the module to a host or supervisory controller. The supply listing specifies 2.5 V to 3.3 V operation, so analog input ranges must remain compatible with the selected I/O and ADC domains. Exact ADC resolution, input impedance, sample rate, reference accuracy, and timing are [DATA_NEEDED: detailed ADC specifications] and must be established before precision measurement claims are made.
推荐
Motor and Motion Control
The STM32F103VBI6TR is relevant to compact motor-control subsystems because the verified feature set includes seven timers, two ADCs, and a 72 MHz Cortex-M3 core. Timers can generate deterministic control waveforms, while ADC inputs can support current, position, or feedback monitoring. The MCU coordinates low-level control functions, but it does not replace power transistors, gate drivers, position sensors, current sensing, or protection hardware. Designers must verify which timer channels provide complementary outputs, the required dead time, pin assignments, ADC trigger latency, and fault-handling behavior in the official documentation. The 100-UFBGA footprint reduces board area but demands fine-pitch assembly and careful exposed-pad thermal management.
推荐
Compact HMI Controller
The STM32F103VBI6TR can support a compact human-machine interface controller where a 72 MHz Cortex-M3 core, 128 KB of Flash, USB, and CAN are required in limited board area. The MCU can manage input events, status logic, communications with a host, and control outputs, while an external display or touch assembly handles the user-facing functions. Its 100-UFBGA package helps reduce routing area in multilayer boards. However, no display-specific peripheral claims should be made from the supplied excerpts, so LCD, touch, and external-memory interfaces must be checked against the official pinout. Firmware partitioning, boot behavior, update security, connector protection, and production programming access also require design-level review.
推荐
Programmable Logic Controller
The STM32F103VBI6TR is suitable for compact PLC and automation controller platforms because it combines a 72 MHz Cortex-M3 core, 128 KB of Flash, seven timers, two ADCs, USB, CAN, and nine communication interfaces. These resources support deterministic input scanning, actuator timing, analog supervision, and supervisory communications in a small embedded module. The 100-UFBGA package permits dense placement on multilayer PCBs, although assembly and inspection requirements increase compared with LQFP alternatives. Engineering teams should confirm I/O voltage limits, pin-muxing, timer resolution, communication baud-rate support, watchdog behavior, and memory endurance in the official documentation. Functional safety or regulatory claims require separate qualification and are not established by the supplied data.

设计说明
Treat the STM32F103VBI6TR 100-UFBGA as a fine-pitch assembly item. Before schematic release, obtain the manufacturer package drawing and verify the exposed pad, pin-one orientation, solder-mask openings, paste apertures, via-in-pad rules, and component placement tolerances. Do not reuse a land pattern from STM32F103VBT6 or another 100-pin package because a different package suffix can represent a physically different footprint. Include PCB access for programming, boundary-scan, or functional test where the selected manufacturing process requires it.
Use the documented 2.5 V to 3.3 V operating range as the initial supply-design boundary, then verify every rail, I/O bank, ADC domain, and peripheral constraint in the official datasheet. The supplied data does not state decoupling values, internal regulator behavior, startup timing, or absolute maximum ratings, so those values are [DATA_NEEDED: power-supply and decoupling requirements]. Do not copy a reference schematic without confirming the package pinout and the exact STM32F103 density and ordering code.
Plan the board around the 100-terminal BGA escape strategy early, especially when USB, CAN, multiple timers, and ADC inputs are required. Separate sensitive analog routing from fast digital and switching-supply paths, and confirm which pins can be used for each function because alternate-function mapping is not present in the supplied excerpts. Maintain continuous ground-plane coverage under the device where the official package recommendation allows it. Validate USB impedance, CAN routing, return paths, and decoupling placement using the final stack-up and manufacturing rules.
The most common sourcing mistake is treating any STM32F103V variant as interchangeable. The VBI6 target is a 100-UFBGA, 7 x 7 mm device, whereas related T6 devices use a different package construction. Similarly, generic GD32F103 articles do not prove that a specific cross-vendor part matches the 100-UFBGA footprint. Require an exact package drawing, terminal table, voltage comparison, clock review, peripheral map, and firmware-porting assessment before approving a replacement as drop-in.
