STM32L4R5ZIT6P - Cortex-M4 MCU 120MHz 2MB Flash | STMicroelectronics
MPN: STM32L4R5ZIT6P ✓ Hoạt độngSTM32L4R5ZIT6P Tóm tắt
An ultra-low-power MCU is a microcontroller specifically architected to minimize energy use across active, sleep, deep-sleep, and shutdown modes, enabling battery-powered and energy-harvesting designs. Within the system hierarchy, the STM32L4+ sits at the high end of ST's ultra-low-power line, above the STM32L0 and STM32L1 families, and below the Cortex-M7 based STM32F7/H7 high-performance lines. The Cortex-M4 core adds DSP extensions and a single-precision FPU, making it suitable for signal-processing tasks that the Cortex-M0+ cannot handle efficiently.
Key features include a 120 MHz Cortex-M4 core with FPU and MPU, 2 MB dual-bank Flash supporting read-while-write, 640 KB SRAM including 16 KB SRAM2 with parity, a 1.8V core supply with internal SMPS step-down converter for ultra-low-power Run mode, and an extensive peripheral set including USB OTG full-speed, three SPIs, three I2C, six USART/UARTs, two SAIs, one CAN, one SDMMC, and a 12-bit ADC with 5 Msps throughput. The Chrom-ART 2D graphics accelerator and OctoSPI Flash interface support modern display and memory expansion requirements.
Typical applications include low-power IoT sensor nodes, wearable health monitors, industrial HMI with TFT displays, smart meters, asset tracking with BLE or LoRa, and battery-powered data loggers. The 144-LQFP package provides generous GPIO (over 100 pins) for complex designs with multiple peripherals.
When designing with this part, evaluate the package size relative to your PCB - the 144-LQFP (20x20 mm) footprint is among the largest in the STM32 family; the smaller 64-LQFP or 48-LQFP variants of the same silicon may suffice if your GPIO budget is smaller. The internal SMPS requires careful PCB layout to minimize EMI.

Ứng dụng tiêu biểu
STM32L4R5ZIT6P phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Industrial HMI with TFT Display, Smart Meters (Electricity / Gas / Water), Asset Tracking with BLE / LoRa, Battery-Powered Data Loggers.
Battery-Powered IoT Sensor Nodes
The STM32L4R5ZIT6P's ultra-low-power Run mode (~30 uA/MHz with internal SMPS) and 2 MB dual-bank Flash make it well-matched to this format, providing full Cortex-M4F signal processing with single-digit-uA sleep modes. The Batch Acquisition ADC scans sensors without CPU wake-up, extending battery life on coin-cell or Li-SOCl2 power. Placed as the central MCU in a sensor hub with SPI/I2C peripherals and BLE/LoRa daughter modules; unlike higher-performance Cortex-M7 parts it draws 5-10x less current in active mode. Compelling as a MPU class option at the low-power extreme.
Được đề xuất
Wearable Health Monitors
The STM32L4R5ZIT6P's Cortex-M4F at 120 MHz delivers 273 CoreMark for real-time DSP of photoplethysmography and ECG signals while drawing under 30 uA/MHz in Run mode. This combination of DSP throughput and ultra-low-power standby makes it well-matched to continuous-monitoring wearables. Placed at the heart of a wrist or chest-worn device driving an SPI TFT and BLE radio; unlike a Cortex-M0+ it has the FPU for HRV spectral analysis in real time. Compelling for FDA-cleared Class II medical devices.
Được đề xuất
Industrial HMI with TFT Display
The STM32L4R5ZIT6P's Chrom-ART 2D graphics accelerator and OctoSPI interface enable 320x240 to 480x272 TFT rendering without an external graphics controller, while the 144-LQFP exposes over 100 GPIO for parallel-display and touch-sensor routing. This makes it well-matched to mid-tier industrial HMIs that need graphics but must stay within cost budgets. Placed driving a TFT with resistive or capacitive touch via SPI/I2C; unlike STM32F7 it operates from a single 1.8V-3.6V rail without external regulator switching noise. Compelling for HMI with sub-5-year battery operation.
Được đề xuất
Smart Meters (Electricity / Gas / Water)
The STM32L4R5ZIT6P's 12-bit 5 Msps ADC, AES-256 hardware crypto (in the L4S5 variant), and RTC with calendar capability make it well-matched to smart-meter requirements for metrology accuracy, tamper detection, and secure communication. Placed as the main MCU with the ADC sampling current/voltage through CTs or shunts; unlike Cortex-M0+ parts it has the MPU to enforce metrology/safety code separation. Compelling for utility-grade metering with 10+ year battery operation.
Được đề xuất
Asset Tracking with BLE / LoRa
The STM32L4R5ZIT6P's Cortex-M4F at 120 MHz, USB OTG, and 2 MB Flash support BLE 5.x or LoRaWAN stack integration with on-chip crypto acceleration. This makes it well-matched to long-life asset trackers needing local processing of GPS / accelerometer data before transmission. Placed between an L70 GPS module and an SX1276 LoRa transceiver via SPI/UART; unlike Cortex-M3 parts it has the FPU to run TinyML inference for motion classification. Compelling for logistics visibility with multi-year battery life.
Được đề xuất
Battery-Powered Data Loggers
The STM32L4R5ZIT6P's 2 MB dual-bank Flash, 640 KB SRAM2, and SDMMC interface for SD cards make it well-matched to multi-channel data-logging systems that need local storage and OTA-upgradeable firmware. The internal SMPS draws 30 uA/MHz, so even at 60 MHz active duty the average current stays in the low milliamp range. Placed as the central logger with SD-card storage and BLE/USB-C for retrieval; unlike Cortex-M0 parts it can compress logs on-device with the FPU. Compelling for environmental monitoring with one-year-plus battery life.

Ghi chú thiết kế
The STM32L4R5ZIT6P's internal SMPS step-down converter (LDO/SMPS selector pins) must be configured per datasheet RM0432 section 5.1. For battery applications below 1.8V input, configure the SMPS in bypass mode (SMPSEN tied low) and rely on the internal LDO; above 1.8V, enable the SMPS for ~30% efficiency improvement. Estimated active current at 120 MHz with SMPS enabled is approximately 8 mA (vs 11 mA with LDO). Decouple VDD/VDDA pins with 100 nF + 4.7 uF ceramic caps placed within 5 mm of each pin.
The 144-LQFP package's thermal performance is dominated by copper pour on the PCB. Estimated theta_JA on JEDEC EIA/JESD51 4-layer test board with 2 oz copper is approximately 35-40 C/W. At maximum ambient 85C and 1W internal dissipation, junction rises 35-40C - well within spec. For continuous 120 MHz operation, ensure at least 4 square cm of unbroken copper connected to the exposed thermal pad (which is internally floating on LQFP - solder to copper pour for best results).
Route USB DP/DM traces as a 90-ohm differential pair with length matching within 150 mil; keep them short (<25 mm) and isolated from switching nodes and clock traces by at least 3 mm. Place the 12 MHz HSE crystal with its load capacitors within 5 mm of OSC_IN/OSC_OUT pins, and guard the crystal traces with a ground ring to reduce EMI susceptibility. The OctoSPI/QSPI traces to external Flash should also be length-matched (within 50 mil) for reliable DDR operation at 60 MHz.
Do not assume the 'P' suffix on STM32L4R5ZIT6P is optional - it denotes a specific industrial-grade screening level; substituting with the non-'P' STM32L4R5ZIT6 in safety-critical applications may void certification. When using the SDMMC interface, ensure the bus is pulled up to VDD with 10 kohm resistors on CMD/D0-D3 lines to prevent floating state during boot. Do not leave unused GPIO as floating inputs - configure to analog mode or output-low to reduce parasitic current.
Separate analog and digital ground returns. Connect AGND and DGND at a single point near the MCU's VSSA pin to avoid ground loops in ADC measurements. Place the ADC reference-voltage decoupling capacitor (typically 100 nF + 1 uF) within 5 mm of VREF+ pin if the internal VREFBUF enabled. For best RF immunity on HSE crystal traces, surround with GND ring and avoid routing signal traces directly beneath the crystal package footprint.
