STM32L496AGI6 - 80MHz Cortex-M4F 1MB MCU | STMicroelectronics
MPN： STM32L496AGI6 ✓ 啟用中STM32L496AGI6 概覽
An ultra-low-power microcontroller is an embedded semiconductor that combines a processor core, memory, peripherals, and low-power operating modes in one integrated circuit. The STM32L4 family belongs to the Arm Cortex-M microcontroller hierarchy and uses the Cortex-M4F core, which adds single-precision floating-point instructions for control, signal-processing, and sensor workloads. Its low-power architecture supports battery-powered and energy-conscious designs without requiring a separate high-performance processor.
The principal device features include 100 DMIPS class performance, up to 1 MB of Flash, 320 KB of SRAM, USB OTG FS, an Arm Cortex-M4F CPU with FPU, and FlexPowerControl low-power operation. Backup-domain operation retains RTC-related functionality and 32 x 32-bit backup registers with a VBAT supply current of 320 nA. Shutdown mode consumes 25 nA and supports five wake-up sources, making the MCU applicable to compact instruments and long-life battery equipment.
The STM32L496AGI6 combines substantial compute and peripheral capability with a 1.71 V minimum operating voltage. This allows designers to use 3.3 V supplies directly while supporting lower-voltage power domains. Its integrated connectivity and security-oriented peripherals can reduce external component count in USB, display, storage, and authenticated data-processing designs. Exact pin assignments, peripheral availability, and operating limits must be confirmed against the STM32L496xx manufacturer datasheet before schematic capture.
Typical applications include industrial sensor hubs, portable medical and laboratory instruments, USB OTG data loggers, compact human-machine interfaces, low-power edge nodes, and audio-capable embedded controls. The USB OTG FS interface is useful for configuration and data transfer, while LCD support and DFSD capability suit display-oriented and removable-storage designs. For designs requiring Ethernet, industrial communication, or low-power wireless links, the companion transceiver or radio must be selected separately.
PCB planning should account for the 169-UFBGA 7 x 7 mm land pattern, exposed-pad thermal requirements, decoupling, signal integrity, and manufacturing capabilities. Place input and bulk decoupling capacitors close to the supply pins, preserve a low-impedance return path beneath the device where supported by the package drawing, and validate the escape-routing strategy before high-volume release. Firmware, boot configuration, supply sequencing, and peripheral pin multiplexing must also match the device variant and package.
This product record combines manufacturer datasheet facts, distributor availability and pricing information, package constraints, application guidance, and a strict drop-in alternative assessment. That engineering-focused synthesis helps distinguish electrical capability from true PCB-level replacement suitability and identifies where procurement data or pin-level validation remains necessary.

典型應用
STM32L496AGI6 適用於 6 應用s: USB-Critical Low-Power Data Logger, Industrial Sensor Hub, Portable Medical Instrument, Compact Human-Machine Interface, Battery-Powered Edge Node, Removable-Storage Data Acquisition Unit.
USB-Critical Low-Power Data Logger
STM32L496AGI6 fits a USB-connected data logger because its Arm Cortex-M4F core operates up to 80 MHz and includes USB OTG FS alongside 1 MB Flash and 320 KB SRAM. The device can buffer sensor readings, encode records, and expose configuration or stored data through USB while retaining low-power shutdown capability. Its 25 nA shutdown specification is useful for duty-cycled deployments, although the practical standby figure also includes regulator leakage, pull networks, and attached sensors. Firmware should preserve RTC context and validate enumerated USB power states before relying on autonomous wake-up operation.
推薦
Industrial Sensor Hub
The STM32L496AGI6 supports an industrial sensor hub that must combine local filtering, data preparation, and low-power behavior in a compact 169-UFBGA package. Its 100 DMIPS-class Cortex-M4F performance, 1 MB program memory, and 320 KB SRAM allow multiple sensor tasks and communication stacks to coexist without moving routine processing to a host processor. The 1.71 V to 3.6 V operating range supports compact supply designs, while shutdown and VBAT modes help reduce energy during inactive periods. Deployment still requires independent verification of EMC immunity, environmental limits, isolation, and field update procedures.
推薦
Portable Medical Instrument
STM32L496AGI6 is applicable to portable instruments that need responsive signal processing, local data storage, and low standby power. The Cortex-M4F core supports single-precision calculations, 320 KB SRAM provides working space for real-time processing, and 1 MB Flash accommodates control firmware and nonvolatile parameters. Its low-voltage operation and 25 nA shutdown mode can support battery life, provided the complete analog front end, display, sensor, and regulator budgets are included. Medical use also demands separate verification of electrical safety, software validation, risk controls, and applicable quality requirements.
推薦
Compact Human-Machine Interface
The STM32L496AGI6 is suited to compact LCD-based controls because the manufacturer datasheet identifies LCD support, USB OTG FS, and 80 MHz Cortex-M4F performance in the same 169-UFBGA device. Designers can run a graphical or menu interface, process operator input, retain configuration in Flash, and update equipment through USB without adding a separate interface controller. The 320 KB SRAM can support display buffering, although framebuffer size depends on resolution and color depth. Production design should confirm the exact LCD interface pin assignment and escape-routing feasibility on the 7 x 7 mm land pattern.
推薦
Battery-Powered Edge Node
STM32L496AGI6 supports battery-powered edge nodes by combining low-power operating modes with enough compute capability for local sensor interpretation and protocol handling. VBAT operation can preserve RTC-related functions and 32 backup registers at a cited 320 nA, while shutdown mode reaches a cited 25 nA with five wake-up sources. The microcontroller can wake periodically, acquire measurements, update state, and return to sleep without relying on a continuously powered host. Actual battery life must be modeled with regulator quiescent current, load-switch leakage, sensor duty cycle, radio activity, and cold-temperature effects rather than from the MCU shutdown figure alone.
推薦
Removable-Storage Data Acquisition Unit
The STM32L496AGI6 is appropriate for data-acquisition units that must store local records and transfer them through USB. Its verified feature set includes DFSD support, 1 MB Flash, 320 KB SRAM, and USB OTG FS, allowing acquisition control, file handling, and host communication to share one microcontroller. The Cortex-M4F core can accelerate filtering and data formatting, while the compact 169-UFBGA package supports dense industrial or portable equipment. Storage media compatibility, card detection, brownout behavior, write endurance, and filesystem fault recovery should be tested with the exact DFSD configuration and memory device.

設計說明
Plan the 169-UFBGA 7 x 7 mm footprint before committing the PCB stack-up. Confirm the land pattern, exposed-pad dimensions, solder-mask policy, and assembly process against the STM32L496xx package drawing. Use the manufacturer footprint rather than scaling a generic BGA pattern, and validate escape routing for power, clocks, high-speed USB, and communications signals using the actual stack-up and manufacturing rules.
Place the closest high-frequency bypass capacitor directly between each selected supply pin and ground, then add bulk capacitance according to the datasheet and transient requirements. Keep the 1.71 V to 3.6 V operating range visible throughout schematic review, including USB-attachment brownouts and external-SMPS startup conditions. Verify that all GPIO states remain acceptable during reset, shutdown, and wake-up so partially powered external circuits cannot backfeed the MCU.
The 169-UFBGA package concentrates heat beneath a small footprint, so thermal performance depends strongly on the exposed pad, PCB copper, via distribution, and enclosure. Use the manufacturer thermal information as the basis for junction-temperature calculations and avoid substituting a generic BGA estimate. For sustained high activity, spread copper where the package rules permit and connect thermal vias according to assembly requirements so solder wicking and voiding do not compromise the heat path.
Separate sensitive analog or sensor inputs from USB, switching-supply, and fast digital return currents. Route clocks and high-speed interfaces over continuous reference planes with minimal stubs, and place decoupling and support components at the pins they serve. In a mixed-signal design, use the MCU power and ground connections as the common reference for return-current planning, then verify crosstalk and USB signal integrity with simulation or measurements on the production stack-up.
Do not treat a similar STM32L4 headline specification as proof of drop-in compatibility. Confirm Flash density, SRAM, package pinout, exposed-pad connection, temperature grade, USB and DFSD resources, clock pins, boot pins, and peripheral mappings. Software migration also requires comparison of interrupt vectors, peripheral instances, HAL or low-level-driver support, and startup code. A hardware footprint match alone does not establish functional equivalence.
