Applications
STM32L451CCU6 is an STMicroelectronics STM32-class microcontroller used in industrial control, consumer electronics, motor drivers, USB devices, and OEM/EMS controller boards. Typical designs lock the UFQFPN-48 footprint, Flash/SRAM size, and peripheral set. Confirm the full ordering code against the ST datasheet before swapping nearby STM32L451 suffixes.
Procurement notes
Confirm the full ordering code, package (UFQFPN-48), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ
Where to buy STM32L451CCU6?
You can request STM32L451CCU6 from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (STMicroelectronics), package, quantity, and lead time on the quotation.
Is STM32L451CCU6 available?
Listed inventory shows 46,070 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of STM32L451CCU6?
The sourcing listing shows package UFQFPN-48. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.
What are alternatives to STM32L451CCU6?
Potential alternatives include STM32L451CCU3, STM32L451CCU3TR, STM32L451CEU6 and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
