Is the STM32H743VIT6 discontinued?
STM32H743VIT6 sits in ST's high-performance H7 line — active production, premium pricing, and periodic allocation on the most popular variants. The 480 MHz-class H743/H723 family is heavily used in industrial HMI and audio, keeping spot demand steady.
Pin-to-pin compatible alternatives
"Drop-in" means same package and pinout; other rows are family alternates that need design review.

STM32H743VIT6 vs STM32H743VIH6: what actually differs
The two most-compared codes differ on: Voltage - Supply (Vcc/Vdd): STM32H743VIT6 = 1.71V ~ 3.6V, STM32H743VIH6 = 1.62V ~ 3.6V; Package / Case: STM32H743VIT6 = 100-LQFP, STM32H743VIH6 = 100-TFBGA.
Everything else in the compared parameter set matches. If your design has margin on the differing parameters, STM32H743VIH6 is a practical substitute; if not, hold out for the exact code — we stock both.
Migration checklist: re-validate before you swap
- H7 flash/RAM variants share die — verify your image and stack fit before downgrading
- Power supply architecture (SMPS vs LDO variants) differs per code — check the exact suffix
- Cache maintenance (D-Cache) behavior is identical within family but differs from F7 ports
- Package pinout must match exactly — TFBGA and LQFP variants are not interchangeable
- Re-validate clock configuration: PLL tree differs across H7 subfamilies
Where to source STM32H743VIT6 and its alternates
We stock STM32H743VIT6 and its family variants in Hong Kong with date codes stated on every quote. Each lot passes marking verification; X-ray and electrical testing through accredited partner labs are available on request, with the report delivered before final payment.
Pricing follows the live spot market, so quotes carry a stated validity window — typically 24 to 48 hours on volatile lines. Send your quantity and required date code and the desk replies within 2 working hours.
STM32H743VIT6 can also ship consolidated with the rest of your BOM — one shipment, one invoice, one inspection standard. For recurring demand we reserve stock and schedule multi-lot releases, which smooths both price exposure and availability risk across your build calendar.

FAQ
Is STM32H743VIT6 discontinued?
No — the STM32H7 family is in active production.
Are H743 variants pin-compatible?
Within the same package, yes — flash size is the main variable.
H743 vs H723 — what differs?
H743 runs at 480 MHz with more peripherals; H723 at 550 MHz with a leaner peripheral set. Same family toolchain, different feature mix.
Do you stock industrial temperature grades?
Yes — suffix matched exactly per ordering code.
Can high-value MCUs be X-rayed before payment?
Yes — X-ray and functional test via accredited partner labs, report before payment on first orders.
What is the quote validity?
24–48 hours on volatile lines; stated on every quote.
Can I see photos or test reports before ordering?
Yes — label and top-marking photos of the actual lot are standard, and X-ray or lab reports can be arranged before payment on first orders. Tell the desk what your incoming inspection requires.
Do you support scheduled production deliveries?
Yes. For recurring demand we reserve stock of STM32H743VIT6 or its alternates and release shipments against your build schedule — one agreement instead of repeated spot buys.
