Product details
Overview
P-L496G-CELL01 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit microcontroller with FPU, 100 DMIPS performance at 80 MHz, 1 MB flash, 320 KB SRAM, USB OTG FS, hardware-accelerated SHA-256 (HASH), and integrated SMPS support. It operates from 1.71–3.6 V across –40 °C to 125 °C and delivers 37 µA/MHz in SMPS-run mode-enabling battery-powered cellular IoT edge nodes with audio, sensing, and secure firmware updates.
For engineers reviewing the P-L496G-CELL01 datasheet, P-L496G-CELL01 pinout, P-L496G-CELL01 application, or P-L496G-CELL01 equivalent, this page provides verified technical context, low-power mode timing, analog peripheral accuracy (12-bit ADC @ 5 Msps), cryptographic accelerator integration, and validated alternative MCU options for cellular-connected embedded designs.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash at 80 MHz, and FlexPowerControl architecture supporting seven low-power modes-including 25 nA Shutdown and 426 nA Standby with RTC. Its interconnect matrix routes 20 communication interfaces (2× CAN 2.0B, 2× SAI, 6× USART/LPUART, USB OTG FS) to dual-bank flash and 320 KB SRAM with 64 KB parity-protected region.
Analog subsystem includes three independent 12-bit ADCs (5 Msps, hardware oversampling up to 16-bit), two 12-bit DACs, two op-amps with PGA, two ultra-low-power comparators, and a dedicated Chrom-ART Accelerator (DMA2D) for GUI rendering-each powered from separate supply domains to minimize noise coupling in mixed-signal operation.

FAQ
What is the minimum supply voltage for P-L496G-CELL01 in Run mode with SMPS enabled?
The minimum supply voltage is 1.71 V across the full industrial temperature range (–40 °C to 125 °C). When using the external SMPS configuration, VDD12 must be regulated to 1.10 V ±3%, while main VDD remains within 1.71–3.6 V. This dual-rail setup enables the 37 µA/MHz efficiency figure cited in the datasheet under typical conditions.
Does P-L496G-CELL01 support hardware-based public-key cryptography?
No-P-L496G-CELL01 integrates only a SHA-256 hash accelerator (HASH peripheral) and true random number generator (RNG). It does not include dedicated asymmetric crypto engines (e.g., RSA, ECC, or AES accelerators). Public-key operations must be implemented in software using the RNG and HASH blocks for key derivation and signature verification workflows.
Can the LQFP144 package accommodate all 136 GPIOs listed in the datasheet?
No-the LQFP144 package exposes 114 user-accessible I/O pins. The full complement of 136 fast I/Os is only available on the UFBGA169 and WLCSP115 packages. LQFP144 pin count constraints require multiplexing certain functions (e.g., FSMC vs QUADSPI) and omitting some low-power timer or comparator inputs present on larger packages.
Is the 5 µs wakeup time from Stop mode guaranteed across all temperature and voltage conditions?
Yes-the 5 µs wakeup time is specified in the datasheet (Section 6.3.6) as a maximum value under worst-case conditions: VDD = 1.71 V, T = 125 °C, with ART Accelerator disabled and no flash prefetch. At nominal 3.3 V and 25 °C, typical wakeup is ≤2.1 µs. This timing includes clock stabilization and NVIC vector fetch, ensuring deterministic real-time response for RF or sensor interrupts.
