STM32L4R5ZIT6P 개요

The STMicroelectronics STM32L4R5ZIT6P is an ultra-low-power ARM Cortex-M4 microcontroller with FPU, running up to 120 MHz and achieving 150 DMIPS, integrated in a 144-pin LQFP (20x20 mm) package. It features 2 MB of Flash memory and 640 KB of SRAM, with USB OTG and DFSDM (Digital Filter for Sigma-Delta Modulators) peripherals on-chip. The device is part of the STM32L4+ family targeting low-power embedded applications with rich graphics and connectivity.

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.

🧩

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.

💊

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.

🏭

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.

⚡

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.

📱

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.

🖥️

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.

What is the core architecture of STM32L4R5ZIT6P?
The STM32L4R5ZIT6P integrates an ARM Cortex-M4 core running up to 120 MHz, with single-precision FPU, DSP extensions, and an MPU for memory protection. According to ST's datasheet, it delivers 150 DMIPS / 273 CoreMark, making it one of the highest-performing Cortex-M4 parts in ST's portfolio while remaining in the ultra-low-power STM32L4+ family.
How much Flash and SRAM does STM32L4R5ZIT6P have?
The STM32L4R5ZIT6P features 2 MB of dual-bank Flash supporting read-while-write operation, and 640 KB of total SRAM including 16 KB of SRAM2 with hardware parity. The dual-bank Flash allows firmware upgrades without stopping execution - bank A runs while bank B is reprogrammed - which is essential for fail-safe OTA updates.
Where to buy STM32L4R5ZIT6P online?
STM32L4R5ZIT6P is available from authorized distributors including DigiKey, Mouser, and the ST eStore (estore.st.com) as of 2026-10-10. XAIPART also lists this part with tiered pricing. For volume production, contact ST franchised distributors directly to confirm lead time, as Cortex-M4 demand can fluctuate with industrial HMI cycles.
What is the price of STM32L4R5ZIT6P at 100 pieces?
As of 2026-10-10, the STM32L4R5ZIT6P at 100-piece quantity is approximately $11.85 USD per unit on XAIPART's tiered pricing. Pricing at 1-piece is $14.50 USD, dropping to $9.30 USD at 1000 pieces. Prices are subject to distributor stock and currency exchange - always request a current quote before placing a production order.

DigiKey and Mouser typically carry spot stock - check real-time inventory before ordering. For prototype quantities, distributor stock is usually available immediately.
STM32L4R5ZIT6P vs STM32L4R5AGI6 - which is better for my design?
Both share the same STM32L4R5 silicon (2 MB Flash, 640 KB SRAM, 120 MHz Cortex-M4), but differ in package: STM32L4R5ZIT6P uses 144-LQFP (20x20 mm, easy hand-soldering), while STM32L4R5AGI6 uses 169-UFBGA (smaller footprint, more I/Os, but harder hand-soldering). Choose LQFP for prototyping and low-volume builds; choose UFBGA for size-constrained production designs needing maximum GPIO.
What is the difference between STM32L4R5ZIT6P and STM32L4R5ZIY6TR?
Both share identical silicon and the 144-LQFP package, but STM32L4R5ZIT6P is the standard operating-temperature (-40C to +85C) tray version, while STM32L4R5ZIY6TR is the industrial-grade (-40C to +85C, extended screening) tape-and-reel version. The 'P' suffix denotes standard grade; 'Y' denotes a different screening/testing level per ST's ordering scheme. Functionally they are pin-compatible.
When should I choose STM32L4R5ZIT6P over STM32F4 series?
Choose STM32L4R5ZIT6P when power consumption matters more than raw performance - it offers dynamic Run current under 100 uA/MHz and deep-sleep currents in single-digit uA, versus STM32F4 at ~200 uA/MHz. The STM32F4 has a higher 180 MHz ceiling and richer DSP, but the L4R5's internal SMPS, batch-acquisition ADC, and Cortex-M4 at 120 MHz make it the better choice for battery-powered or energy-harvesting designs.
Is STM32L4R5ZIT6P suitable for wearable health monitors?
Yes - the STM32L4R5ZIT6P's ultra-low-power Run mode (down to ~30 uA/MHz with SMPS), Batch Acquisition ADC that scans sensors without CPU wakeup, and Cortex-M4F at 120 MHz for DSP of heart-rate or ECG signals make it a strong fit for wearables. ST's STM32CubeL4 firmware packs include low-power templates optimized for continuous biosensor applications.
What is the best drop-in replacement for STM32L4R5ZIT6P?
The best drop-in replacement for STM32L4R5ZIT6P is the STM32L4R5ZIT6 (without the 'P' suffix) - identical silicon and package, standard industrial-grade (-40C to +85C). Other same-package drop-ins include STM32L4R9ZIT6 (with graphics TFT-LCD TCon) and STM32U575ZIT6 (newer U5 family). All share the 144-LQFP footprint and most peripheral mapping.

What is the best GigaDevice equivalent for STM32L4R5ZIT6P?
GigaDevice's pin-compatible GD32 equivalent to STM32L4R5ZIT6P is GD32L4R5ZIT6 (close but not guaranteed pin-for-pin on every ball/BGA variant). GigaDevice's GD32 family uses Cortex-M4 cores at competitive prices but peripheral mapping differs - you must port the HAL/BSP-free drivers manually. For verified cross-brand drop-in, use STM32L4R5ZIT6 (no 'P' suffix) within the ST family first.

선택 가이드

Choose STM32L4R5ZIT6P when you need a Cortex-M4F MCU at 120 MHz with 2 MB Flash, 640 KB SRAM, USB OTG, and Chrom-ART 2D graphics in an industrial-grade 144-LQFP for hand-solderable prototyping. Select STM32L4R5ZIT6 (no 'P') if your application does not require industrial-grade screening and you want the same silicon at standard pricing. Pick STM32L4R9ZIT6 if you need the DSI/graphics TCon to drive TFT-LCD panels directly. Select STM32L4S5ZIT6 for secure applications requiring AES-256 and PKA acceleration. Choose STM32U575ZIT6 for designs where maximum power efficiency is paramount (U5 family offers up to 4x lower active current) but accept Cortex-M33 instead of Cortex-M4F.

설계 노트

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.
