STM32L496ZGT6 - 80MHz Cortex-M4 1MB MCU | STMicroelectronics
MPN: STM32L496ZGT6 ✓ Hoạt độngSTM32L496ZGT6 Tóm tắt
An ultra-low-power microcontroller is a semiconductor designed to balance substantial processing capability with minimized energy consumption. The STM32L4 series belongs to the hierarchy of Arm Cortex-M4 MCU, 32-bit RISC microcontroller, embedded controller, and low-power system-on-chip. STM32L496ZGT6 combines that processing capability with sleep, low-power, shutdown, and RTC-oriented operating modes, making it suitable for battery-powered and energy-conscious embedded systems.
Principal features include a 1.71 V to 3.6 V operating supply, a 32-bit Cortex-M4 processor with floating-point unit, 1 MB Flash, 320 KB SRAM, and USB OTG full-speed connectivity. The analog subsystem provides up to three fast 12-bit ADCs sampling at 5 Msps, two comparators, two operational amplifiers, two DAC channels, and an internal voltage-reference buffer. 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.

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.

Ứng dụng tiêu biểu
STM32L496ZGT6 phù hợp cho 6 Áp dụngs: Battery-Powered Sensor Nodes, USB Connected Test and Measurement, Industrial Automation and Control, Medical Monitoring Equipment, Motor Control and Power Conversion, Secure Data Logging and Storage.
Battery-Powered Sensor Nodes
The STM32L496ZGT6 fits battery-powered environmental sensors because its Arm Cortex-M4 core runs at up to 80 MHz while the STM32L4 low-power architecture supports shutdown current of 25 nA with five wakeup pins. The 320 nA VBAT mode can maintain the RTC and 32 x 32-bit backup registers while the main supply is removed. Use the ADC, comparators, and two operational amplifiers for local sensor conditioning, then schedule periodic acquisition and transmission cycles to control average current draw.

USB Connected Test and Measurement
STM32L496ZGT6 is appropriate for USB-connected measurement equipment because it combines an 80 MHz Cortex-M4 with FPU, 320 KB SRAM, USB OTG FS, and fast analog conversion resources. Up to three 12-bit ADCs can operate at 5 Msps, while two comparators, two operational amplifiers, and two DAC channels support excitation, thresholding, and signal generation. Its 144-pin LQFP package also provides extensive I/O for display control, communication, data acquisition, and front-panel interfaces.

Industrial Automation and Control
The STM32L496ZGT6 supports industrial control applications that require deterministic real-time processing alongside extensive mixed-signal I/O. Its 100 DMIPS Cortex-M4 performance, dedicated motor-control PWM timers, general-purpose timers, and multiple ADC channels can manage motion or process-control loops. The 1.71 V to 3.6 V operating range supports low-voltage industrial logic, while the 144-pin package offers enough pins for isolated communications, sensors, actuators, and local human-machine interfaces.

Medical Monitoring Equipment
STM32L496ZGT6 can serve as the central controller in medical monitoring and diagnostic equipment that combines signal acquisition with low-power operation. The 12-bit ADC bank, comparators, operational amplifiers, and DAC channels provide an integrated analog foundation, while the Cortex-M4 FPU handles filtering and control algorithms. Its low-power modes are useful in portable instruments, although every medical design must independently validate electrical safety, isolation, accuracy, and applicable regulatory requirements.
Được đề xuất
Motor Control and Power Conversion
The STM32L496ZGT6 is suitable for motor-control and power-conversion systems that require fast control logic and multiple mixed-signal resources. Two 16-bit PWM timers dedicated to motor control, two general-purpose 32-bit timers, and seven general-purpose 16-bit timers support motor-drive and power-control architectures. External SMPS support is valuable in systems requiring coordinated DC-DC conversion, while the ADC and comparators can monitor voltage, current, and fault conditions.
Được đề xuất
Secure Data Logging and Storage
STM32L496ZGT6 fits secure data-logging systems that need local processing, flexible storage interfaces, and cryptographic hardware. The 80 MHz Cortex-M4 can format and compress sensor data, 320 KB SRAM supports buffering, and DFSD provides an integrated route to compatible flash storage. The HASH block can assist integrity-related operations, while USB OTG FS enables connected configuration or data transfer. Designers should review the exact DFSD support configuration and security requirements in the manufacturer documentation.

Ghi chú thiết kế
Design the supply network around the STM32L496ZGT6 operating range of 1.71 V to 3.6 V, including voltage tolerance and startup sequencing for every external rail. Place the manufacturer-recommended bypass capacitors at their associated power pins and keep high-current return paths away from sensitive analog inputs. If external SMPS is used, preserve the recommended power-stage layout and verify startup, fault behavior, and sequencing with the final component values.
Treat the 144-pin LQFP as a high-pin-count mixed-signal layout. Keep analog inputs away from switching nodes and digital return currents, provide a continuous ground reference beneath the MCU where practical, and route USB, oscillator, and sensitive sensor signals with short paths. Check the package drawing for exposed or thermal structures and follow the manufacturer land-pattern dimensions rather than estimating them from generic LQFP drawings.
Do not select a replacement solely because it uses a 20 x 20 mm LQFP package. Confirm all 144 pin functions, supply pins, ground pins, debugging signals, analog inputs, and timer mappings against the STM32L496xx datasheet. Also verify temperature grade, qualification, errata, bootloader behavior, and peripheral clock configuration. Firmware built for the target should be regression-tested with the exact replacement order code.
At 80 MHz, validate junction temperature using actual switching activity, GPIO load, supply voltage, and the package thermal model in the manufacturer documentation. The STM32L496ZGT6 offers low-power operating modes, so thermal performance should be evaluated in the highest-duty-cycle state rather than inferred from idle current. Use copper spreading and airflow according to enclosure temperature and the board’s heat-dissipation capability.
Low-power shutdown specifications do not by themselves determine battery life. Account for sensor standby currents, regulator quiescent current, USB or communication activity, wakeup latency, and the duration of each acquisition cycle. Verify that the five shutdown wakeup pins are assigned to signals that must remain valid during wakeup and that the RTC and backup-domain retention behavior matches the product requirements.
Thông tin tuân thủ
The base STM32L496ZGT6 ordering suffix does not identify an automotive-qualified order code. Exact RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations should be confirmed from the current manufacturer product documentation or declaration of compliance.
