STM32L452VCI6 - 80MHz Cortex-M4 MCU | STMicroelectronics
MPN： STM32L452VCI6 ✓ 啟用中STM32L452VCI6 概覽
An ultra-low-power microcontroller is a semiconductor controller optimized to complete sensing, control, communications, and data-processing tasks while minimizing active and standby energy consumption. Within the product hierarchy, the STM32L452VCI6 is an Arm Cortex-M4 MCU, a 32-bit RISC microcontroller, and a member of STM32L4 power management-oriented embedded devices. Its USB and DFSDM interfaces distinguish it from basic low-power MCUs while its 7 x 7 mm package supports space-constrained designs.
The principal verified features include an Arm Cortex-M4 processor with FPU, operation up to 80 MHz, and 256 KB of Flash storage. The Cortex-M4 architecture supports efficient embedded control and digital signal-processing workloads, while the FPU accelerates suitable floating-point calculations. USB Device support enables the MCU to communicate with a host computer or USB-equipped peripheral, and DFSDM provides a dedicated path for external analog data acquisition.
The STM32L452VC family is positioned for applications requiring a balance between processing performance, low-power operation, analog connectivity, and compact packaging. Its 256 KB of Flash provides embedded program storage, while the STM32L4 platform is designed for energy-sensitive products that need more capability than a basic low-power MCU but do not require a high-performance application processor.
Typical uses include USB-connected data acquisition equipment, low-power industrial sensing modules, compact audio or communication products, environmental monitoring devices, and portable instrumentation. DFSDM is particularly relevant when an application must acquire signals through an external sigma-delta converter while avoiding a general-purpose ADC for every input. The 100-UFBGA package also helps reduce board area where that benefit outweighs assembly and inspection complexity.
Designers should verify the complete pin assignment, exposed-pad requirements, power sequencing, decoupling, and operating-temperature limits against the manufacturer datasheet before layout release. The 7 x 7 mm BGA footprint also demands assembly processes capable of inspecting fine-pitch solder joints. Firmware and peripheral configurations should be checked in detail because USB, DFSDM, clocking, and low-power modes can affect both board design and software architecture.
This product page consolidates verified manufacturer and distributor information, distinguishes the target from same-family options, and adds application guidance, comparison parameters, and practical design cautions that are not organized together in the manufacturer datasheet.

典型應用
STM32L452VCI6 適用於 6 應用s: USB-Connected Sensor Module, Industrial Environmental Monitoring, Portable Audio and Communication Device, Low-Power Data Acquisition Unit, Compact Medical Monitoring Instrument, USB-C Enabled Embedded Controller.
USB-Connected Sensor Module
The STM32L452VCI6 fits a compact USB-connected sensor module because it combines an 80 MHz Arm Cortex-M4F processor, USB Device support, and 256 KB of Flash in a 100-UFBGA 7 x 7 mm package. The MCU can acquire sensor data, perform local filtering, format results for a USB host, and manage power-efficient operating modes. Its DFSDM capability is useful when an external sigma-delta converter handles analog acquisition. The compact BGA reduces board area, but fine-pitch assembly and exposed-pad layout require careful PCB and thermal planning.
推薦
Industrial Environmental Monitoring
The STM32L452VCI6 is appropriate for industrial environmental monitoring equipment that must combine local signal processing with low-power operation. Its 80 MHz Cortex-M4F core can execute measurement algorithms, while the 256 KB Flash provides embedded application storage. USB Device connectivity supports configuration transfer and data export to a laptop or service computer. The 7 x 7 mm 100-UFBGA package is useful for densely packaged field units, provided the assembly line can reliably inspect BGA solder joints and the enclosure provides suitable thermal conditions.
推薦
Portable Audio and Communication Device
The STM32L452VCI6 can serve as the control processor in a portable audio or communication product requiring USB, digital signal processing, and low-power operation. The Cortex-M4F core provides hardware floating-point support for filtering and protocol tasks, while DFSDM can accept signals from suitable external converters. Its 256 KB Flash supports embedded control firmware, and USB Device connectivity simplifies charging, configuration, or data exchange with a host. The 100-UFBGA construction supports compact products but requires deliberate acoustic, antenna, grounding, and RF-layout isolation.
推薦
Low-Power Data Acquisition Unit
The STM32L452VCI6 is well matched to a low-power data-acquisition unit that must sample analog inputs and transfer results through USB. DFSDM provides a dedicated interface for compatible external sigma-delta converters, and the 80 MHz Cortex-M4F processor can perform digital filtering before data transfer. The target's 256 KB Flash provides program storage for control, calibration, and USB firmware. A key engineering consideration is matching converter bandwidth, clocking, and output data rates to the acquisition requirement while keeping the overall system within its power budget.
推薦
Compact Medical Monitoring Instrument
The STM32L452VCI6 can support compact medical monitoring instruments when its low-power architecture, USB connectivity, and digital processing capability align with the design. The Cortex-M4F core can handle control logic and selected signal calculations, while the 256 KB Flash stores firmware and configuration data. DFSDM may be used with suitable external sensing front ends. Because the supplied data does not provide medical-specific qualification, developers must verify applicable safety, regulatory, EMC, and quality requirements separately rather than assuming medical certification.
推薦
USB-C Enabled Embedded Controller
The STM32L452VCI6 fits embedded controller designs that use USB Device connectivity to exchange configuration, logs, and control data with a host computer. Its 80 MHz Cortex-M4F core provides ample performance for peripheral coordination and real-time control, while 256 KB of Flash supports embedded application code. The compact 100-UFBGA package can reduce board footprint in wearables, test fixtures, and compact industrial controls. USB layout must include correct data-line routing, impedance control, connector protection, and verified power provisioning.

設計說明
Treat the 7 x 7 mm 100-UFBGA as a fine-pitch BGA and follow the manufacturer land pattern exactly. Confirm pad dimensions, solder-mask definition, exposed-pad geometry, via-in-pad requirements, and stencil thickness using the official package drawing. Keep USB differential routing continuous with controlled impedance, and isolate high-current or switching supply paths from sensitive analog and DFSDM inputs.
Build the supply network around the exact operating modes required by the application. Verify core, digital, and analog rail limits, startup sequencing, decoupling values, and external-SMPS requirements in the manufacturer datasheet. Calculate worst-case supply dissipation and regulator headroom rather than assuming that a low-power MCU remains low power when USB, DFSDM, analog blocks, and the 80 MHz core operate simultaneously.
The 100-UFBGA has limited exposed thermal area and is sensitive to assembly voids and uneven soldering. Review the manufacturer land-pattern and assembly guidance, control solder-paste volume, and inspect hidden joints. Where the operating environment or sustained 80 MHz activity creates a thermal risk, improve copper spreading beneath the package and route heat toward a larger board area without compromising USB or analog signal integrity.
Do not infer a replacement from the family name alone. Verify the ordering-code temperature grade, Flash and SRAM density, USB implementation, DFSDM pins, clock requirements, and startup behavior for the exact MPN. The T6, K6, H6, E6, and I6 suffixes represent ordering details that must be resolved from ST ordering information; firmware and PCB changes may be required if they affect pin function or memory capacity.
合規資訊
The supplied verified snippets do not state the target part's RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance claim has been inferred from the manufacturer identity.
