Product details
Overview
STM32L4P5AGI6P from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 120 MHz (150 DMIPS), featuring 1-MB Flash, 320-KB SRAM, LCD-TFT controller, and integrated external SMPS support. It delivers 2.95 µA Stop 2 mode with RTC, 41 µA/MHz Run mode in SMPS configuration, and supports capacitive touch sensing for battery-powered industrial HMI applications.
For engineers reviewing the STM32L4P5AGI6P datasheet, STM32L4P5AGI6P pinout, STM32L4P5AGI6P application, or STM32L4P5AGI6P equivalent, key selection criteria include verified low-power mode current values (e.g., 190 nA Standby with RTC), dual-bank read-while-write Flash architecture, hardware parity on 64 KB SRAM, and validated Octo-SPI interface timing for high-speed external memory interfacing.
Technical Context
The device integrates an adaptive real-time accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 120 MHz, alongside a memory protection unit (MPU) and dual-bank Flash supporting true read-while-write operation. Its power architecture includes three independent voltage regulators (LDO/SMPS/VREFBUF) and FlexPowerControl logic managing 7 distinct low-power modes.
Peripherals are routed via a multi-AHB bus matrix with 14-channel DMA, supporting concurrent high-bandwidth transfers - e.g., simultaneous DCMI image capture, SAI audio streaming, and OCTOSPI memory access - without CPU intervention.

FAQ
What is the maximum operating temperature range for STM32L4P5AGI6P?
The STM32L4P5AGI6P is rated for operation from –40 °C to +85 °C ambient temperature, with extended variants supporting up to +125 °C. This rating is validated per DS12903 Rev 3 Section 6.3.1, and applies to all low-power modes including Stop 2 and Standby with RTC. Thermal derating begins above 85 °C for sustained operation.
Does STM32L4P5AGI6P support hardware encryption acceleration?
Yes - it integrates a dedicated SHA-256 hardware accelerator (HASH module) and a True Random Number Generator (RNG) compliant with NIST SP800-90B. These modules operate independently of the CPU, enabling secure key generation, firmware signature verification, and TLS handshake acceleration without impacting real-time application performance.
Can STM32L4P5AGI6P drive a color TFT display directly?
Yes - its integrated LCD-TFT controller (LTDC) supports RGB interface up to 24-bit color depth, programmable pixel clock, and hardware synchronization signals (HSYNC/VSYNC/DE). It drives common parallel RGB panels (e.g., 480×272, 800×480) without external display controllers, and pairs with DMA2D for efficient layer composition and alpha blending.
How many I/O pins support independent VDDIO2 supply?
Up to 14 I/O pins (grouped as PH0–PH15, excluding PH3–PH15 used for LTDC) can be supplied from an independent VDDIO2 rail down to 1.08 V. This enables direct interfacing with low-voltage peripherals (e.g., 1.2 V or 1.8 V sensors, memories) while maintaining full 5 V tolerance on other GPIOs - confirmed in DS12903 Rev 3 Section 3.11 and Table 15.
