STM32L162QCH6 - 32MHz Cortex-M3 MCU | STMicroelectronics
MPN: STM32L162QCH6 ✓ Hoạt độngSTM32L162QCH6 Tóm tắt
An ultra-low-power microcontroller is a semiconductor device designed to minimize energy consumption during active operation, standby, and low-power modes. STM32L1 devices belong to the broader hierarchy of ARM Cortex-M3 microcontrollers, embedded processors, and semiconductor control components. This makes the STM32L162QCH6 relevant to battery-powered instruments, industrial controls, medical equipment, connected sensors, and compact human-interface systems.
Verified listing data identifies a 32-bit Cortex-M3 core operating at 32 MHz, 256 KB Flash, 32 KB SRAM, and 8 KB EEPROM. The device also includes USB, LCD, ADC, DAC, and AES-128 hardware acceleration according to the available technical summaries. Its 2.5 V to 3.3 V supply description reflects a low-voltage embedded platform intended for efficient digital control and mixed-signal designs.
The STM32L162QCH6 provides 132 package connections, allowing integration of multiple I/O resources and communication peripherals on a compact surface-mount footprint. The verified distributor listing identifies the package as 132-UFBGA, while another result describes the same device as a 132-pin package. The package pinout and exact electrical limits should be confirmed against the manufacturer datasheet before PCB release.
Typical applications include USB-connected portable instruments, low-power sensor nodes, LCD-based user interfaces, industrial monitoring systems, and secure embedded controllers. Compared with a general-purpose Cortex-M3 MCU, the STM32L162 family is positioned around low-power operation and integrated features such as LCD, USB, DAC, and AES-128 support.
Designers should preserve the manufacturer-recommended decoupling, clock, reset, and exposed-power connections. USB signal routing requires controlled impedance and short traces, while low-power and analog sections should be separated carefully to reduce noise coupling. Validate final firmware against the exact order code and package variant.
This page consolidates verified distributor specifications, sourcing information, application guidance, and drop-in-alternative validation limits for STM32L162QCH6. It is intended to support engineering comparison, procurement review, and preliminary design work rather than replace the manufacturer datasheet or qualification process.

Ứng dụng tiêu biểu
STM32L162QCH6 phù hợp cho 6 Áp dụngs: USB Portable Instrumentation, Low-Power Sensor Node, LCD-Based User Interface, Industrial Monitoring Controller, Secure Connected Embedded Control, Battery-Powered Data Logger.
USB Portable Instrumentation
The STM32L162QCH6 fits portable instruments that use a low-power Cortex-M3 control platform while retaining USB connectivity, 256 KB Flash, and 32 KB SRAM. A typical design places the MCU near the USB connector and implements controlled-impedance routing, local decoupling, and a stable 2.5 V to 3.3 V supply. The verified USB feature can simplify host-connected logging or configuration, but the designer must confirm the exact USB pins, transceiver requirements, firmware class support, and electrical layout in the manufacturer package documentation.
Được đề xuất
Low-Power Sensor Node
For a battery-powered sensor node, the STM32L162QCH6 provides an ultra-low-power MCU position, 32 MHz processing, 32 KB SRAM, and serial interfaces including I2C, SPI, and UART/USART. The device can supervise an external sensor, filter readings, and enter a controlled low-power state between samples. ADC availability supports analog sensing, while DMA can reduce CPU involvement. Actual battery life depends on the verified sleep currents, sensor load, wake timing, regulator efficiency, and firmware duty cycle.
Được đề xuất
LCD-Based User Interface
The STM32L162QCH6 is appropriate for compact LCD user-interface products because the verified feature summary identifies LCD support alongside 32 KB SRAM and 256 KB Flash. The MCU can manage display updates, button input, menu state, and low-power screen behavior in a single embedded platform. The 132-UFBGA package offers many external connections, but the exact LCD interface mapping and ball availability must be verified. Use the manufacturer reference configuration and preserve the required LCD timing and power sequencing.
Được đề xuất
Industrial Monitoring Controller
The STM32L162QCH6 can serve as the central controller in an industrial monitoring unit that combines sensor acquisition, status reporting, and local control. Its verified Cortex-M3 core, 32 MHz clock, ADC, DAC, DMA, watchdog, and multiple serial interfaces support common monitoring architectures. A practical design should isolate analog and digital sections, provide robust decoupling, and define safe behavior during brownout or communication loss. The manufacturer datasheet and product qualification should govern industrial environmental requirements.
Được đề xuất
Secure Connected Embedded Control
The verified AES-128 hardware encryption accelerator makes the STM32L162QCH6 relevant to embedded systems that require hardware-assisted cryptographic operations. Combined with USB and serial connectivity, it can support secure configuration exchange, authenticated control messages, and firmware-oriented communication. Hardware acceleration reduces the processor workload for supported cryptographic operations, but it does not replace secure key storage, protocol design, certificate validation, or secure boot. Keep sensitive keys and debug access under an appropriate security architecture.
Được đề xuất
Battery-Powered Data Logger
The STM32L162QCH6 is a reasonable candidate for a battery-powered data logger that must store firmware locally, capture sensor data, and communicate through USB or a serial interface. Its 256 KB Flash provides room for application code and configuration, while 32 KB SRAM supports buffering and protocol processing. USB can simplify retrieval of logged data, although storage endurance and write-cycle requirements depend on the external data medium. Validate the complete power budget because the available data does not specify a universal battery-life figure.

Ghi chú thiết kế
Keep the MCU supply, decoupling, and ground return layout within the manufacturer reference configuration. The verified supply range is 2.5 V to 3.3 V, but the exact operating limits, regulator tolerance, startup behavior, and peripheral current budget must be taken from the official datasheet. Place bulk and high-frequency decoupling close to the relevant power balls, and verify startup current against the selected supply source.
For USB operation, use short, controlled-impedance traces and a layout that follows the manufacturer reference. Confirm the exact USB ball assignments, series-resistance requirements, pull-up implementation, and connector placement from the package data. Avoid routing USB through noisy power-regulator or switching-node areas. Signal-integrity validation with the intended host, cable, connector, and power supply is necessary before production.
The 132-UFBGA package requires careful escape routing and a PCB stackup compatible with the manufacturer land pattern. Confirm ball pitches, solder-mask and paste recommendations, thermal-via requirements, and assembly profile from official package drawings. Do not infer the footprint from a generic 132-BGA library. A PCB review should include drill, pad, routing, inspection, and stencil checks before fabrication.
Do not treat STM32L152QCH6 as an automatic drop-in replacement until every ball assignment and peripheral function is compared with the STM32L162QCH6 datasheet. Related family naming does not guarantee identical USB, LCD, ADC, DAC, AES, memory, clock, or software behavior. Also confirm that the quoted $2.7286 LCSC price and the separately reported $8.5974 reference price are current for the required quantity.
