The qualification system for automotive microcontrollers
From a customer RFQ to a defensible AURIX pick, across all 77 public devices. Every recommendation explained, every claim sourced.

Customer requirement
“We're architecting a zonal controller for our next-gen EV platform. Need serious compute headroom for sensor fusion and some on-device inference, CAN-XL support, full ASIL-D, viable for a ~10 year platform. SOP Q3 2027.”
Routed to TC4x
- AI/PPU acceleration requested → TC4x is the AI-capable generation.
- CAN-XL required → introduced with the TC4x generation.
- High compute + zonal/SDV context → TC4x is built for this architecture.

Disqualified, at any score
- TC48xNo AI accelerator (PPU) listed, but on-device AI acceleration is required
- TC45xMax ASIL-B below required ASIL-D
Built only from public sources: the AURIX product brochure and series pages, 5 competitors’ own product pages, and 12 regulatory texts. Where they are silent, it says so.
1.0 Qualify
Answer an RFQ in one pass. Requirements, hard gates and a scored shortlist you can question in chat.
Paste or upload the customer's document. It becomes numbered requirements, each quoting the customer and carrying a must, should or nice priority, then a line-by-line compliance matrix you can export.

2.0 Defend
A pick you can sign. Every factor shows its weight, every claim links its source.
A missing must-have disqualifies outright; it is never averaged away. Where the public data is silent the answer is “verify”, not a number, and out-of-scope requests are escalated rather than guessed.

Bar = fit on that factor; right = its weight. Proxy factors are derived by this tool, not published, and say so.
3.0 Win
Know where the portfolio wins. 22 applications, scored against every device.
Megatrends and regulation decide which sockets open next. Each application is placed on the car and scored against all 77 devices, with 12 regulatory clocks, so it shows where AURIX leads, where it contends, and where there is a gap to close.

Best technical fit among eligible AURIX devices in this project's own scoring against public product pages — not market share.
4.0 Compete
See who else is bidding. Rival families, read from their own product pages.
Each AURIX device set against 7 competitor families from 5 vendors on 13 dimensions, with every figure read from the vendor’s own page.
- NXPS32K3 · S32G
- RenesasRH850/U2B
- STStellar P6 (SR6 P6) · Stellar G6 (SR6 G6)
- TIAM263x (AM2634)
- SemiDriveE3
5 of the 13 dimensions (price, power, availability, customer base, time-to-market) are published by no vendor, AURIX included. They are listed as gaps, never estimated.
