Applications

STMUX1800LQTR 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 QFN-56 footprint, Flash/SRAM size, and peripheral set. Confirm the full ordering code against the ST datasheet before swapping nearby STMUX1800L suffixes.

Procurement notes

Confirm the full ordering code, package (QFN-56), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ

Where to buy STMUX1800LQTR?

You can request STMUX1800LQTR 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 STMUX1800LQTR available?

Listed inventory shows 9,165 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 STMUX1800LQTR?

The sourcing listing shows package QFN-56. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.

What are alternatives to STMUX1800LQTR?

Potential alternatives include STMUX1800LQTR-ST, STMUX1800LFN00F, STMUX1000LQ 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.
