Frequently asked questions
Is the STM32F446ZEH7TR still orderable, or is it obsolete?
The lifecycle_stage is eol_hot, meaning STMicroelectronics has flagged this part at end-of-life heat — the last-time-buy window is active or closing. Active catalog status can coexist with eol_hot during the draw-down period, but the eol_hot designation is the controlling sourcing flag. RFQ now for Q3 requirements.
Is the ZEH7TR interchangeable with the ZET6?
No — the ZEH7TR is in a 144-UFBGA (ball-grid array, 10x10mm) and the ZET6 is in LQFP-144 (leaded). They share the same die but not the package. The UFBGA requires a different baseboard layout, stencil design, and BGA-level rework capability. If you need LQFP-144 compatibility, source the ZET6 instead.
What is the availability window for a 100-unit Q3 build?
With eol_hot lifecycle status, the window is closing. Authorized-distributor allocation is being drawn down; broker-channel stock carries authenticity risk at this stage of lifecycle. Submit an RFQ now to lock in allocation before the last-time-buy date closes.
Does the USB OTG peripheral support BC 1.2 charging downstream for a 2A port design?
The USB OTG hardware is present, but BC 1.2 charging downstream-port compliance and host negotiation protocol support depend on the firmware implementation and the specific ST silicon revision. An external USB PHY may be required for a 2A charging port design — consult the ST datasheet and your USB certification plan.
