 AI Summary | STM32L562CEU6 by STMicroelectronics: ARM® Cortex®-M33 STM32L5 Microcontroller IC 32-Bit 110MHz 512KB (512K x 8) FLASH 48-UFQFPN (7x7). | The STM32L552CEU6 belongs to the same STM32L5 series and shares the exact same package, memory configuration, and pinout as the STM32L562CEU6. The only difference is that it lacks the dedicated hardware cryptographic acceleration engines (AES, PKA, OTFDEC), making it a perfect drop-in replacement if hardware-accelerated security functions are not strictly needed by your firmware.
| The STM32L552CCU6 is a more cost-effective sibling that shares the exact same package and pinout. It reduces the onboard Flash to 256 KB (down from 512 KB) and lacks the hardware cryptographic accelerators, while keeping the same core processor and 256 KB RAM. It is ideal if your firmware footprint is smaller and does not require hardware cryptography.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
