STM32L486ZGT3 - 80MHz Cortex-M4 1MB MCU | STMicroelectronics
N.º da peça: STM32L486ZGT3 ✓ AtivoSTM32L486ZGT3 Visão geral
A microcontroller is a programmable system-on-chip containing a processor core, memory, and peripherals on one package. The STM32L4 family belongs to the broader hierarchy of embedded processors, 32-bit microcontrollers, and low-power embedded systems. STM32L486 devices combine general-purpose control performance with energy-oriented features suited to battery-powered, industrial, sensing, communications, and human-interface applications.
Three headline characteristics define this particular device. Its Arm Cortex-M4 processor supports 32-bit execution at up to 80 MHz, while the single-bank 1 MB flash arrangement provides room for application code and firmware updates. Its 144-lead LQFP package exposes a broad set of GPIO and peripheral connections while supporting automated board assembly. The STM32L486 platform also provides USB OTG, AES, LCD, and floating-point features identified in the verified product and distributor information.
The exact RAM capacity, operating-temperature limits, supply-current figures, ADC characteristics, timer counts, and detailed peripheral inventory were not included in the supplied verified excerpts. Those values remain intentionally unspecified in the specification table rather than being inferred from related devices. The available data instead confirms the device family’s ultra-low-power positioning and the target part’s 80 MHz maximum frequency, 1 MB flash configuration, USB OTG support, LCD support, and AES capability.
Typical uses include industrial sensor controllers, compact data acquisition equipment, USB-connected peripherals, low-power instrumentation, LCD-equipped human-interface panels, and embedded communications equipment. The 144-pin package makes the MCU appropriate when a design needs numerous discrete signals rather than a small microcontroller with only a few exposed pins.
Engineering designs must verify the exact pin functions, alternate-function mappings, decoupling requirements, clock tree, and peripheral electrical limits against the official STM32L486ZG documentation before layout release. Pin multiplexing also requires a consistent allocation across USB, LCD, debug, communications, and general-purpose I/O. Power sequencing and exposed 144-lead assembly demand careful board-level thermal and contamination controls.
This page consolidates the verified manufacturer identity, package, core, memory, interface, voltage, and sourcing information into an engineering-oriented resource. It also identifies where drop-in family alternatives require firmware, feature, and peripheral verification rather than assuming that a shared package guarantees complete behavioral equivalence.

Aplicações típicas
STM32L486ZGT3 é adequado para 6 aplicaçãos: Industrial Sensor Controllers, USB Connected Embedded Peripherals, Low-Power Data Acquisition, LCD Human-Interface Panels, Battery-Powered Portable Instruments, Communications and Network Control.
Industrial Sensor Controllers
The STM32L486ZGT3 fits industrial sensor controllers that require an 80 MHz Arm Cortex-M4 core, 1 MB of flash, and a high pin count in a 20 x 20 mm LQFP package. Its 32-bit processing architecture supports concurrent acquisition, sensor conditioning supervision, filtering, and local control tasks. The verified STM32L486 family positioning emphasizes ultra-low-power operation, while the exact ADC performance and timer resources must be checked against the official documentation. Engineers should assign peripheral pins only after reviewing the complete alternate-function matrix and should reserve robust grounding, filtering, and protection for industrial sensor inputs. The shared 144-LQFP format of the listed STM32L4 family candidates can simplify footprint planning, but firmware migration, memory size, and peripheral-equivalence checks remain mandatory before using any alternative.
Recomendado
USB Connected Embedded Peripherals
The STM32L486ZGT3 is appropriate for USB-connected embedded peripherals because the verified product information identifies USB OTG alongside the 80 MHz Cortex-M4 core and 1 MB flash. A designer can place protocol handling, device control, configuration storage, and status reporting in one microcontroller while retaining many GPIO and peripheral options through the 144-LQFP footprint. The excerpt does not establish USB speed, endpoint count, PHY implementation, or bus-power requirements, so those details require confirmation in the official manual. PCB implementation must separate analog and digital return paths, provide the required USB data and power connections, and account for connector and ESD design. The listed same-package STM32L4 alternatives cannot be treated as USB-equivalent without verifying their USB controller and firmware support.
Recomendado
Low-Power Data Acquisition
The STM32L486ZGT3 supports low-power data-acquisition designs that combine a 32-bit Cortex-M4 core running up to 80 MHz with 1 MB of program storage. The processor can manage sampling control, digital filtering, calibration tables, and host communications while the STM32L4 family’s ultra-low-power positioning addresses energy-sensitive instrumentation. The verified excerpts do not specify ADC resolution, analog input count, sample rate, timer count, or operating current, so acquisition accuracy and channel density must be established from the complete official STM32L486ZG documentation. Layout should place analog inputs, references, and the MCU return path carefully, while firmware should include settling, calibration, and low-power duty-cycle control. Any family substitution must be checked for identical ADC, DMA, timer, and memory resources rather than package fit alone.
Recomendado
LCD Human-Interface Panels
The STM32L486ZGT3 is well suited to LCD-equipped human-interface panels because the verified listing identifies LCD support, an 80 MHz Cortex-M4 core, and 1 MB of flash for graphics, controls, and communication firmware. Its 144-pin package can expose display, touch, navigation, communications, and general-purpose I/O through the STM32L4 family’s broad peripheral selection. The supplied data does not state the supported display interface, framebuffer size, external memory requirements, or contrast interface details, so panel-specific compatibility must be verified. Engineering teams should plan panel bus routing away from sensitive analog signals, use appropriate drive and bias components, and confirm that the selected LCD peripheral remains available on the exact orderable MPN. A replacement candidate is suitable only after checking display controllers, memory, and pin multiplexing rather than merely matching the LQFP-144 footprint.
Recomendado
Battery-Powered Portable Instruments
The STM32L486ZGT3 can serve as the primary controller in a battery-powered portable instrument because the STM32L486 family is explicitly described as ultra-low-power, while the target offers 80 MHz processing and 1 MB flash. The 32-bit Cortex-M4 architecture and FPU support can reduce computation time in measurement, control, and user-interface routines, although actual battery life depends on the complete power-mode configuration and peripheral activity. The supplied excerpts do not include sleep-mode current, wake-up timing, analog accuracy, or regulator requirements, so these values must be checked before sizing a battery. Designers should use low-power modes, switch off unused peripheral domains, control display and communications duty cycles, and measure the assembled system rather than relying on core-frequency assumptions alone. Drop-in candidates require complete power, wake-up, and peripheral compatibility checks.
Recomendado
Communications and Network Control
The STM32L486ZGT3 fits communication hubs, gateways, and network-control modules that benefit from 80 MHz processing, 1 MB flash, and numerous package connections. Its Arm Cortex-M4 architecture can handle protocol processing, local routing, status monitoring, and configuration management while USB OTG provides a verified connectivity option. The available data does not enumerate Ethernet MAC, CAN, serial-interface, or external-transceiver support, so engineers must map required communication interfaces to verified pins before schematic capture. Signal integrity, impedance control, connector protection, and isolation become increasingly important as interface rates rise. Although several STM32L4 family parts share the 144-LQFP footprint, a replacement must preserve the required communication peripherals, pin multiplexing, memory configuration, clocking, and software support. Package equivalence alone does not establish interoperability.

Notas de projeto
Use the official STM32L486ZG power-supply and decoupling guidance before assigning analog or digital rails. The verified listing confirms 1.8 V, 2.5 V, and 3.3 V operating configurations, but it does not provide current limits, sequencing rules, or capacitor values. Place required bulk and high-frequency capacitors at their associated supply pins with short, low-loop-area connections, and keep sensitive analog returns separate from switching return currents where the reference design permits.
Reserve the complete 144-LQFP land pattern, courtyard, solder mask, and paste geometry from the official package drawing rather than scaling dimensions from a generic LQFP library. The verified package is 20 x 20 x 1.4 mm, but body and lead dimensions must come from the exact mechanical drawing. Leave unobstructed access for inspection and consider pin-1 orientation, lead coplanarity, and assembly clearances before releasing the PCB footprint.
Assign pins only after checking the complete alternate-function table for USB, LCD, debug, clock, communications, and GPIO requirements. The supplied excerpts confirm USB OTG and LCD support but do not expose the 144-pin mapping. Plan signal groups by function, provide short return paths for high-speed interfaces, and avoid routing sensitive sensor or reference signals beneath switching nodes. PCB review should also verify that no planned function conflicts with the selected package variant.
Do not treat a shared 144-LQFP footprint or a close MPN suffix as proof of drop-in equivalence. Verify flash size, SRAM, peripheral availability, USB and LCD functions, clock limits, pin multiplexing, boot configuration, and software support for each candidate. STM32L486ZET3 and STM32L486ZCT3 have less flash than the STM32L486ZGT3, while STM32L475 and STM32L496 alternatives can differ in family features. Record the exact approved orderable MPN before production release.
Informações de conformidade
The supplied manufacturer and distributor excerpts do not explicitly state material-compliance declarations for this exact orderable MPN. AEC-Q100 is marked not applicable because the provided data does not identify an automotive-qualified orderable variant.
