It runs from a 1.71 V to 3.6 V supply and offers a -40 °C to 85 °C industrial temperature range. A microcontroller (MCU) is a single silicon device that bundles a CPU core, program memory, working RAM and a rich set of peripherals onto one package. In the power-management hierarchy an MCU belongs to the embedded processing family, sitting above simple 8-bit controllers and alongside DSP, FPGA and application-processor alternatives. The STM32L4 series is defined by ST's FlexPowerControl architecture, which keeps standby, shutdown and low-power-run currents at tens to hundreds of nanoamperes while retaining full Cortex-M4 performance. Key differentiators of the STM32L496AEI6 include 320 nA consumption in VBAT mode for RTC and 32 backup registers, a 25 nA shutdown mode with 5 wake-up pins, and a suite of integrated connectivity: USB OTG full-speed with crystal-less support, audio interfaces (SAI, I2S, SAI), crypto accelerators (AES, HASH, RNG), and support for external switched-mode power supplies through the SMPS pin. A 12-bit ADC, dual DAC and comparators round out the analog peripherals. Architecturally, the device combines a 4.17 MHz Cortex-M4 core with a flexible power scaler, multiple low-power modes, an LCD segment/display controller, and up to 108 I/O in the 169-ball option.

The STM32L496AGI6 is suitable for industrial embedded systems, low-power data acquisition, compact user interfaces, USB-connected controls, and secure-connected equipment. 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.

These resources reduce the need for external signal-conditioning and conversion components. The device also integrates two general-purpose 32-bit timers, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and two low-power timers. USB OTG FS, audio support, HASH, DFSD, and external SMPS capability broaden its use across data acquisition, secure control, industrial communication, and low-power consumer equipment. Its low-power architecture includes FlexPowerControl, 320 nA VBAT operation for the RTC and backup registers, and a 25 nA shutdown mode with five wakeup pins. Typical applications include industrial sensor nodes, USB-connected instrumentation, battery-powered data loggers, medical monitoring equipment, motor-control systems, and portable measurement products. The 144-pin LQFP provides ample external peripheral connectivity while supporting designs that need more I/O than smaller MCU packages. Designers should review the complete pin-description table, power-supply requirements, decoupling recommendations, clock configuration, and low-power constraints in the manufacturer datasheet before finalizing the PCB. In particular, preserve the external SMPS interface layout and assign wakeup pins carefully so shutdown-mode entry does not interfere with required system behavior. This page organizes the STM32L496ZGT6 core specifications, package information, design guidance, qualification factors, and same-footprint alternatives. It also distinguishes orderable temperature-grade variants from the selected STM32L496ZGT6 configuration so engineers can assess replacement compatibility without changing the LQFP-144 board footprint.

STM32L4A6AGI6 - 80MHz Cortex-M4 MCU | STMicroelectronics

The STMicroelectronics STM32L4A6AGI6 is an ultra-low-power 32-bit microcontroller built around the Arm Cortex-M4 processor, operating up to 80 MHz with 1 MB Flash and 320 KB SRAM in a 169-UFBGA 7 x 7 mm package. It combines 100 DMIPS, a floating-point unit, USB OTG FS, LCD support, AES hardware acceleration, audio peripherals, DFSDM, and an external switched-capacitor power-supply controller. A microcontroller is a programmable integrated circuit that combines a CPU core, memory, communication interfaces, timers, analog conversion blocks, and GPIO in one device. In the system hierarchy, the STM32L4A6AGI6 is a Cortex-M4 MCU, an embedded microcontroller, a semiconductor, and a member of the STM32L4 family. This integration lets a compact product perform control, communications, data acquisition, security, and low-power management without separate discrete controllers. Verified headline features include an Arm Cortex-M4 core with FPU at up to 80 MHz, 100 DMIPS, 1 MB of Flash organized as 1M x 8, and 320 KB of SRAM. The part also provides USB OTG FS, audio support, AES plus HASH, digital filtering for sigma-delta modulators, an LCD interface, and a high-performance external SMPS controller. These resources support firmware consolidation while keeping the board area below that of several discrete processors. The STM32L4A6xG family emphasizes ultra-low-power operation and performance efficiency. Its Cortex-M4 processing core, fast GPIO, communication peripherals, analog functions, and security hardware make it suitable for connected sensing, industrial equipment, human-interface systems, and compact control platforms. The exact package pin assignments and electrical limits should be checked against the official 169-ball data before layout release. Typical applications include USB-connected data acquisition, industrial sensor hubs, low-power gateways, audio-control systems, security-aware embedded controllers, and LCD-based human-interface devices. The 80 MHz Cortex-M4 core provides useful processing headroom, while 1 MB Flash and 320 KB SRAM reduce pressure on external memory for moderate firmware and data workloads. A key design consideration is BGA assembly: the 169-UFBGA package is not a hobbyist-friendly footprint and benefits from careful escape routing, controlled impedance, adequate thermal vias, and manufacturing capability. Firmware and peripheral assignments must also be validated because unused balls, power balls, and special-function balls are package-specific. This page consolidates verified manufacturer and distributor information, exact source links, practical design guidance, pricing data, and replacement analysis that are not presented as a single connected engineering resource on ordinary distributor listings.

STM32L4A6QGI6 - 80MHz Cortex-M4 1MB MCU | STMicroelectronics

The STMicroelectronics STM32L4A6QGI6 is an ultra-low-power 32-bit Arm Cortex-M4 microcontroller rated up to 80 MHz, with 1 MB of Flash memory and a 132-ball UFBGA package measuring 7 x 7 mm. The device also includes USB OTG, LCD, and AES capabilities, as identified in the supplied manufacturer and distributor listings. An ultra-low-power microcontroller is an embedded processing component designed to balance compute performance, energy consumption, and peripheral integration. The STM32L4A6 belongs to the STM32L4 family of 32-bit RISC microcontrollers. Its Arm Cortex-M4 core places it above basic 8-bit and 16-bit embedded controllers in processing capability while retaining a compact, low-power architecture suitable for battery-powered and industrial systems. The principal verified specifications are an 80 MHz operating frequency, 1 MB of Flash, a 32-bit Arm Cortex-M4 processor, and a 132-UFBGA package. Distributor listings also identify USB OTG, LCD support, and AES functionality. One distributor source additionally lists 114 I/O. These integrated features can reduce the number of external devices required in designs that need USB connectivity, display control, or hardware-assisted secure data processing. Technically, the STM32L4A6QGI6 is intended for low-power embedded control. Its Cortex-M4 architecture supports efficient interrupt-driven firmware, while the integrated communications and security-oriented features broaden its applicability beyond basic sensor reading or actuator control. The exact RAM size, voltage range, ADC characteristics, GPIO current ratings, and detailed power-consumption figures are not included in the supplied verified excerpts and should be confirmed in the manufacturer documentation before design release. Typical uses include compact USB-connected control equipment, low-power industrial sensor nodes, display-oriented embedded controls, and security-conscious portable products. The 7 x 7 mm UFBGA package supports dense PCB layouts, although exposed-pad layout, escape routing, assembly profile, and pin-level connectivity require careful review before layout signoff. The primary design consideration is that a 132-ball package demands disciplined PCB layout and manufacturing controls. Place decoupling capacitors close to supply pins, preserve the package thermal and electrical land pattern specified by STMicroelectronics, and validate USB impedance, power sequencing, and signal routing against the relevant device documentation. This page consolidates the verified manufacturer and distributor facts, distinguishes documented capabilities from unavailable parameters, and provides package-aware replacement guidance and practical integration notes rather than presenting unsupported specifications as confirmed facts.
