STM32L162ZDT6 - 32MHz Cortex-M3 MCU 384KB Flash USB AES | STMicroelectronics
MPN: STM32L162ZDT6 ✓ Hoạt độngSTM32L162ZDT6 Tóm tắt
What is an ultra-low-power microcontroller? An ultra-low-power microcontroller is a category of embedded MCU optimized to consume the least energy in active and sleep modes. It belongs to the broader taxonomy microcontroller -> embedded processor -> semiconductor device. The STM32L1 family positions itself for battery-powered applications where every microamp counts, including metering, medical portables, IoT sensors and wearable electronics.
Key features include 7 low-power modes, RTC with backup registers, integrated LCD driver up to 8x40, AES-128 hardware accelerator, USB 2.0 full-speed device with on-chip PHY, 12-bit ADC and DAC, multiple comparators, and up to 114 general-purpose I/Os on the 144-LQFP variant. The ARM Cortex-M3 core runs at 32 MHz, providing 1.25 DMIPS/MHz while drawing roughly 230 uA/MHz active, an order of magnitude lower than legacy Cortex-M3 microcontrollers.
The device is built on a 130 nm ultra-low-leakage CMOS process with embedded Flash, and supports 1.8 V to 3.6 V supply operation. The architecture includes a nested vectored interrupt controller, bit-banding, MPU, and JTAG/SWD debug interfaces. Hardware AES-128 accelerates encryption with zero CPU load, while the LCD controller with charge pump drives segment displays directly.
Typical applications include battery-powered medical instruments, wireless sensor nodes, smart metering, industrial control with HMI segment displays, asset tracking, and USB-enabled data loggers. The 384 KB Flash supports rich application firmware with over-the-air upgrade capability and protocol stacks such as USB, BLE through SPI, or LoRaWAN via external transceiver.
When designing with the STM32L162ZDT6, carefully select the appropriate low-power mode (Stop, Standby, Sleep) based on wake-up latency and residual current budget. The USB peripheral requires a 1.5 kohm pull-up and proper PCB stack-up for signal integrity; the AES engine uses 128-bit key only.

Ứng dụng tiêu biểu
STM32L162ZDT6 phù hợp cho 6 Áp dụngs: Battery-Powered Smart Metering, Portable Medical Instruments, Industrial Sensor Hubs with Segment Display, Secure IoT Asset Tracker, USB Data Loggers, Wireless Sensor Nodes (Sub-GHz/ZigBee Bridges).
Battery-Powered Smart Metering
The STM32L162ZDT6 fits smart electricity/gas/water meters where multi-year battery life, secure data logging, and segment LCD are essential. Its 230 uA/MHz active current and 1.7 uA Standby with RTC allow coin-cell operation for 10+ years. The AES-128 hardware accelerator secures consumption telemetry against tampering. The integrated LCD controller with charge pump directly drives a 4x40 segment display for cumulative kWh without extra driver ICs. With USB, firmware upgrades in the field are simple via the meter service port, eliminating returns to factory.
Được đề xuất
Portable Medical Instruments
Portable medical devices such as glucose meters, pulse oximeters, and infusion pumps require low-power operation, secure patient data, and small display HMI. The STM32L162ZDT6's 12-bit ADC samples sensor signals accurately, its AES-128 protects data at rest per HIPAA-style requirements, and the LCD controller drives the segment display with no additional driver. Stop modes with RTC wakeup at 1 uA enable week-long operation on small Li-ion batteries. The USB 2.0 full-speed interface transfers measurement logs to a clinician's PC without special cables.
Được đề xuất
Industrial Sensor Hubs with Segment Display
Industrial sensor hubs aggregate multiple analog and digital signals, display status via segment LCD, and connect via USB to factory networks. The STM32L162ZDT6 provides the 12-bit ADC with multiple channels for thermocouples, RTDs, and 4-20 mA loops. Its LCD controller with built-in charge pump drives operator displays directly, simplifying BOM. The AES-128 secures Modbus/TCP and fieldbus traffic; the RTC with backup registers timestamps events during power loss. Wide -40C to +85C operation handles factory floor environments without derating.
Được đề xuất
Secure IoT Asset Tracker
Battery-powered asset trackers combine GPS, motion sensors, and wireless uplinks; they must stay in service for months while securely logging location trails. The STM32L162ZDT6's AES-128 encrypts GPS coordinates and movement data on-device, while its 7 low-power modes put the device into deep sleep between location pings. Stop-mode current under 1.7 uA with RTC extends battery life; the USB port handles firmware updates and tethered debugging. The 384 KB Flash holds the main firmware plus over-the-air upgrade buffer, eliminating external memory cost.
Được đề xuất
USB Data Loggers
USB data loggers that plug directly into PCs need a built-in USB PHY, internal Flash for buffering, and low sleep current between sessions. The STM32L162ZDT6 integrates USB 2.0 full-speed with on-chip PHY, eliminating external components. Its 384 KB Flash stores weeks of samples; AES-128 protects sensitive logs at rest. Stop with RTC mode keeps the device in low-power state until connected. The USB bus-powered operation also charges a small supercap, enabling brief disconnect-tolerant acquisition.
Được đề xuất
Wireless Sensor Nodes (Sub-GHz/ZigBee Bridges)
Wireless sensor nodes combining the STM32L162ZDT6 with a sub-GHz or 2.4 GHz transceiver benefit from the MCU's low active current and AES-128 for link-layer security. The 32 MHz Cortex-M3 handles MAC layer protocols and encryption; the 48 KB SRAM accommodates packet buffers for sub-GHz protocols. The 384 KB Flash stores ZigBee or proprietary stacks. Stop-mode current under 2 uA with RTC allows multi-year battery life for environmental monitoring and building automation deployments.

Ghi chú thiết kế
Estimated: at 32 MHz active the core draws roughly 7.4 mA from 3.3 V (230 uA/MHz x 32 MHz). In Stop mode with RTC active the current falls to about 1.7 uA. Use the PWR->CR register to enter Stop or Standby modes; enable RTC and IWDG wakeup sources as needed. For battery life math, assume 0.1% active duty cycle for typical metering to budget a 600 mAh cell for 5-7 years.
Decouple all VDD pins with 100 nF ceramic capacitors as close to the package as possible. Place one bulk 4.7 uF per pair of VDD/VSS pins. Keep the analog VDDA/VREF+ decoupling isolated from digital VDD noise; consider a ferrite bead between the analog and digital supplies for ADC accuracy below 1 LSB.
Route the USB DP/DM pair with 90 ohm differential impedance and length matching within 150 mil. Place the 1.5 kohm pull-up on D+ close to the MCU with minimal stub. For RTC crystal (32.768 kHz), keep traces short and surrounded by ground guard ring to minimize capacitive loading and frequency drift.
Do not enable USB without a 3.0 V nominal supply (USB transceivers need >= 2.7 V). When using the LCD controller, do not exceed the maximum segment pin loading per pin (typically 8 mA sink). Ensure BOOT0 is pulled to ground for normal boot or to VDD for bootloader mode; floating BOOT0 causes intermittent boot failure.
