主な用途
STM32L162VCT6 の用途: 6 件s: USB-Connected Low-Power Sensor Node, LCD Instrument Control Panel, Secure Access-Control Terminal, Industrial Data Logger and Condition Monitor, Compact Human-Machine Interface, USB-to-Industrial Protocol Gateway.
USB-Connected Low-Power Sensor Node
The STM32L162VCT6 fits a USB-connected environmental or industrial sensor node because its 32 MHz Arm Cortex-M3 core can service timed sensor acquisition and local filtering while 256 KB of Flash holds application firmware, protocol stacks, and calibration data. USB connectivity provides a direct wired interface without a companion communications controller, and the integrated 128-bit AES accelerator can accelerate protection of transmitted measurements or configuration data. The 100-pin LQFP package exposes substantially more GPIO than a compact 48-pin MCU, supporting displays, status indicators, and multiple sensors. Designers should use the manufacturer's USB clock and power guidance, validate the device's low-power current budget, and reserve decoupling close to each supply pin. This architecture favors deterministic local control over a USB connection while retaining a larger, serviceable package for industrial assembly.
おすすめ
LCD Instrument Control Panel
The STM32L162VCT6 is appropriate for an LCD-equipped measurement or control panel because the STM32L1 family combines an LCD interface with a 32 MHz Cortex-M3 processor and 256 KB of program Flash. The processor can update a graphical or segmented display while handling keypad input, temperature compensation, and communication tasks, reducing the need for a separate display controller. The LQFP-100 package provides a broad selection of GPIO for display segments, backlight control, buttons, and status LEDs. Its 2.5 V to 3.3 V supply range supports 3.3 V panel electronics, subject to each connected signal's logic limits. Designers should confirm the selected LCD's voltage, bias, and segment requirements against the datasheet, route display lines away from high-current edges, and test display performance across the complete operating-temperature range.
おすすめ
Secure Access-Control Terminal
The STM32L162VCT6 supports a secure access-control terminal that stores credentials locally, drives a keypad and display, and communicates with a host. Its 128-bit AES hardware accelerator distinguishes it from the STM32L151 and STM32L152 variants because cryptographic operations can be executed without burdening the general-purpose Cortex-M3 core. At 32 MHz, the MCU can perform protocol handling, event logging, and user-interface work concurrently, while 256 KB of Flash provides space for firmware, certificates, and protocol code. The 100-pin LQFP package also leaves I/O available for a secure element, reader, and anti-tamper switches. Engineers should still validate the cryptographic workflow, key-storage architecture, certificate update process, and side-channel expectations rather than treating the AES block as a complete security solution.
おすすめ
Industrial Data Logger and Condition Monitor
The STM32L162VCT6 can serve as the central controller in a compact industrial data logger that records temperature, vibration, voltage, and process-state information. Its 32 MHz Cortex-M3 core provides deterministic scheduling for sampling and filtering, while 256 KB of Flash accommodates firmware and event buffers; external storage can be added for larger records. The 100-pin LQFP footprint provides enough GPIO for multiple analog channels, digital status inputs, and an external communications interface. The integrated AES hardware can accelerate encryption of stored or exported records, and USB permits direct configuration or data export. A practical design should include independent brownout and power monitoring, input protection, watchDog strategy, and verified data-retention planning. Use the manufacturer low-power guidance if the logger must operate for long periods on battery or harvested energy.
おすすめ
Compact Human-Machine Interface
The STM32L162VCT6 is well matched to a compact HMI that combines a low-power display, capacitive or mechanical controls, and a communications link. The LCD capability, 32 MHz processing speed, and 256 KB Flash provide enough resources for icon rendering, menus, logging, and remote-update logic in one device. The Cortex-M3 core provides efficient interrupt servicing for touch or key events, and the large 100-pin package makes external display driver and input-expansion options practical. Its 2.5 V to 3.3 V operating supply can support 3.3 V peripherals, although display glass and driver interfaces require individual verification. Layout should separate sensitive display and touch inputs from USB, switching supplies, and clock sources. Firmware should include brownout recovery and controlled restart behavior so the interface remains dependable during supply transients.
おすすめ
USB-to-Industrial Protocol Gateway
The STM32L162VCT6 can act as a gateway between a USB host and industrial field-bus or sensor network when low power and integrated security matter. Its 32 MHz Cortex-M3 processor can frame and validate incoming data, while 256 KB of Flash holds USB stacks, protocol converters, and diagnostic firmware. The 128-bit AES accelerator is useful when the gateway must protect configuration or authenticated telemetry, and the large LQFP package provides pins for multiple serial interfaces, status LEDs, and isolated communications transceivers. Designers should confirm the target interface's electrical timing and arbitration requirements, because no alternative peripheral set is implied by the shared core. Use isolated transceivers and appropriate protection at external connector pins. Firmware partitioning and watchdog recovery are important for a gateway that must continue operating after host resets or bus faults.

設計ノート
Implement the STM32L162VCT6 power tree from the manufacturer reference configuration, including the required local decoupling on every supply pin and separate return paths for analog and digital loads. The verified operating range for this device is 2.5 V to 3.3 V, but that range does not by itself define the permitted voltage on every GPIO. Use the datasheet's core-voltage and IO-voltage constraints to select compatible external devices. Estimated: if the calculated regulator loss is P = (VIN - VOUT) x IOUT, record VIN, VOUT, and IOUT during worst-case analysis; do not use this estimate as a substitute for the device's specified current and thermal limits.
Place all decoupling and bulk-supply components directly at the corresponding LQFP-100 pins, with the shortest possible return path through the ground plane. Keep the USB data trace geometry controlled and consult the manufacturer's USB layout guidance before routing a USB interface. Because the supplied source extract does not contain the complete pin table, do not assign oscillator, SWD, LCD, or USB nets by memory. Verify every connection against the official STM32L162xC pin description and package drawing before fabrication. This is especially important for a drop-in substitution because identical package dimensions do not guarantee identical alternate-function assignments.
Do not treat an STM32L151 or STM32L152 variant as code-identical to the STM32L162 merely because it uses the same LQFP-100 outline. The principal functional difference is the STM32L162's 128-bit AES hardware accelerator, and peripheral configuration or firmware dependencies may also change. Before substitution, compare every used pin, clock configuration, peripheral instance, interrupt vector, USB descriptor implementation, and device identifier. Rebuild and test the firmware for the exact ordering code. Also verify temperature-grade and reel or tray ordering suffixes separately; the suffix changes procurement and qualification meaning even when the electrical feature set is close.
For USB-connected or LCD-equipped designs, follow the manufacturer layout and reference-design guidance for high-speed data, display timing, and sensitive analog inputs. Keep switching-regulator nodes and high-current outputs away from LCD inputs, external clock lines, and analog channels. Provide a continuous reference plane beneath the LQFP footprint and route escape paths in the order recommended by the package drawing. The exact maximum USB and LCD timing limits were not included in the verified extract, so compliance must be measured against the datasheet and the operating conditions of the selected external device. Estimated timing margins should be calculated from the actual clock and board-level load, not assumed.
コンプライアンス情報
The supplied excerpts do not contain explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 statements. The target is presented as a 100-pin LQFP microcontroller rather than an automotive-qualified ordering code, so AEC-Q100 is recorded as not applicable. Confirm declarations and material compliance on the current STMicroelectronics product page before release.
