Product details
Overview
STM32L4P5CGT6P from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, 120 MHz max frequency, 1-MB Flash, 320-KB SRAM, and integrated LCD-TFT controller. It features FlexPowerControl for 22 nA Shutdown mode, 42 nA Standby mode (5 wakeup pins), and external SMPS support-enabling battery-powered medical sensors and portable HMI displays.
For engineers reviewing the STM32L4P5CGT6P datasheet, STM32L4P5CGT6P pinout, STM32L4P5CGT6P application, or STM32L4P5CGT6P equivalent, key selection criteria include verified low-power mode timing (5 µs Stop wakeup), dual-bank Flash read-while-write capability, hardware parity on 64 KB SRAM, and LQFP48 package compatibility with existing STM32L4 layout footprints.
Technical Context
The device integrates an adaptive real-time accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 120 MHz, and a multi-AHB bus matrix supporting concurrent access to Flash, SRAM, and peripherals. Its power architecture includes three independent voltage regulators (LDO/SMPS/VBAT) and dynamic voltage scaling across six operating ranges.
Peripherals are routed via a configurable interconnect matrix with 14-channel DMA, supporting simultaneous high-bandwidth transfers-for example, Octo-SPI memory streaming to LTDC framebuffer while ADC oversampling runs in background. The dual 12-bit ADCs operate up to 5 Msps with hardware oversampling to 16-bit resolution, each with dedicated 200 µA/Msps power efficiency.

Applications
| Portable Medical Monitor | Smart Energy Meter HMI |
|---|---|
Use Scenario: Battery-operated handheld device displaying ECG waveforms and vital signs with touch-enabled UI. IC Role / Device Role / Timing Role: Primary application MCU managing ADC sampling (ECG front-end), LTDC-driven color TFT display, capacitive touch sensing, and Bluetooth LE communication. Use Value: 190 nA Standby+RTC enables multi-week shelf life; dual-bank Flash permits secure over-the-air firmware patches without interrupting patient monitoring. |
Use Scenario: DIN-rail mounted electricity meter with graphical LCD showing consumption trends, tariff schedules, and tamper alerts. IC Role / Device Role / Timing Role: System controller interfacing metrology ASIC via SPI, driving 480×272 RGB TFT via LTDC, and logging data to external FRAM via Octo-SPI. Use Value: External SMPS support achieves <100 µA average system current in metering mode; hardware CRC and HASH (SHA-256) ensure firmware integrity against unauthorized modification. |
| Industrial Wireless Sensor Node | Low-Power Building Automation Panel |
Use Scenario: Self-powered environmental node measuring temperature, humidity, and CO₂, transmitting data via LoRaWAN every 15 minutes. IC Role / Device Role / Timing Role: Central processor acquiring sensor data via I²C/ADC, managing LoRa transceiver via UART, and entering Stop2 mode between transmissions. Use Value: 2.95 µA Stop2+RTC allows 10-year battery life on two AA cells; 5 µs wakeup ensures minimal latency when scheduled sensor reads trigger. |
Use Scenario: Wall-mounted HVAC control panel with capacitive buttons, ambient light sensing, and RS-485 Modbus gateway functionality. IC Role / Device Role / Timing Role: Human interface controller running TSC for touchkeys, ADC for light sensor, and dual USARTs for local UI and fieldbus communication. Use Value: 136 I/Os with 5 V tolerance simplify integration with legacy 5 V peripherals; independent VDDIO2 supply enables mixed-voltage I/O domains (e.g., 3.3 V MCU core + 1.8 V display interface). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power Cortex-M4 MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L4R5ZIT6 | Same core/peripherals but 2-MB Flash, 640-KB SRAM, UFBGA144 (144-pin); no external SMPS interface | Better suited for complex GUIs requiring larger framebuffer or OTA update partitions | Select when >1 MB Flash or >320 KB SRAM is required; avoid if LQFP48 footprint or SMPS control is mandatory |
| STM32L552RET6 | ARM TrustZone-enabled, 110 MHz max, 512 KB Flash, 256 KB SRAM, 25 nA Shutdown, no LTDC or Octo-SPI | Designed for secure boot and cryptographic services-not for display-intensive or high-speed memory expansion | Choose only when hardware root-of-trust and AES/SHA acceleration are primary requirements over display or memory bandwidth |
Compared with STM32L4R5ZIT6, the STM32L4P5CGT6P trades Flash/SRAM capacity for LQFP48 compactness and SMPS control-making it optimal for space-constrained, battery-sensitive designs. Versus STM32L552RET6, it prioritizes graphics throughput and memory interface flexibility over security isolation, fitting HMI-first rather than security-first use cases.

FAQ
What is the maximum operating frequency and associated power consumption in Run mode?
The STM32L4P5CGT6P operates up to 120 MHz. In Run mode with ART Accelerator enabled and internal LDO, typical current is 110 µA/MHz; with external SMPS, it drops to 41 µA/MHz at 3.3 V. These values are measured with code executing from Flash, cache enabled, and prefetch disabled per DS12903 Rev 3 Table 25 and Table 26.
Does this MCU support hardware encryption acceleration?
Yes-it integrates a dedicated HASH hardware accelerator supporting SHA-256, and a true random number generator (RNG) compliant with NIST SP800-90B. However, it does not include AES or PKA accelerators; those are present only in the STM32L5 and STM32U5 series.
Can the LCD-TFT controller drive a 480×272 RGB display at 60 Hz?
Yes-the LTDC supports up to 24-bit RGB888 output with programmable pixel clock, horizontal/vertical synchronization, and data enable timing. Driving 480×272 at 60 Hz requires a ~9.5 MHz pixel clock, well within the LTDC's maximum 80 MHz limit and compatible with the LQFP48's available RGB signal pins (up to 16-bit data + sync signals).
What debug interfaces are supported, and is SWD sufficient for full development?
The device supports Serial Wire Debug (SWD), JTAG, and Embedded Trace Macrocell (ETM). SWD is fully sufficient for programming, breakpoint-based debugging, and real-time variable monitoring; ETM enables instruction trace for performance profiling. No external debug probe beyond standard ST-LINK/V2-1 is required for complete firmware development.
