Package Information

Package: WLCSP
Package Family: BGA
Mounting: Surface Mount (SMT)
Outline Note: Package marking on this page is for sourcing reference. Confirm body size, pitch, and land pattern from the manufacturer datasheet before layout.

Applications

STM32WB55VEY7TR 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 WLCSP footprint, Flash/SRAM size, and peripheral set. Confirm the full ordering code against the ST datasheet before swapping nearby STM32W suffixes.

Procurement notes

Confirm the full ordering code, package (WLCSP), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ

Where to buy STM32WB55VEY7TR?

You can request STM32WB55VEY7TR 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 STM32WB55VEY7TR available?

Listed inventory shows 39,016 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 STM32WB55VEY7TR?

The sourcing listing shows package WLCSP. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.

What are alternatives to STM32WB55VEY7TR?

Potential alternatives include STM32WB55VGY7TR, STM32WB55VGQ7, STM32WB55RGV6U 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.
