  Cypress' (now Infineon's) developer-facing surface is local: ModusToolbox
  tools, BSPs, HAL/PDL, AIROC, and CapSense libraries are compiled into
  firmware images that run on PSoC, AIROC, and TRAVEO silicon. There is no
  central HTTP API to throttle. Throughput is bounded by the underlying
  transport (UART, SPI, QSPI, USB, BLE, Wi-Fi) and the silicon's clock and
  sample rate, not by a vendor rate-limit policy. The only network-facing
  Infineon surfaces relevant to developers are the Infineon Developer
  Community forum and the GitHub-hosted documentation/release downloads,
  which inherit GitHub's standard rate limits rather than imposing a Cypress
  / Infineon policy.
notes: >-
  Limits are bus / silicon bound and per-device, documented in each part's
  datasheet rather than a network rate-limit page.

limits:
  - name: Per-Device Bus Throughput
    scope: device
    metric: varies
    limit: 'see part datasheet (SPI/QSPI/I2C/UART/USB bus speed)'
  - name: AIROC Wi-Fi Link Throughput
    scope: device
    metric: bits-per-second
    limit: 'bounded by 802.11 PHY of CYW43xxx / CYW55xxx variant'
  - name: AIROC Bluetooth Link Throughput
    scope: device
    metric: bits-per-second
    limit: 'bounded by Bluetooth Core spec (LE 2M PHY ~2 Mbps PHY rate, application throughput lower)'
  - name: GitHub Release Downloads
    scope: developer
    metric: requests
    limit: 'inherits github.com rate limits (60/hr unauthenticated, 5000/hr authenticated)'
policies:
  - name: Local SDK
    description: >-
      ModusToolbox tools and embedded libraries are local; rate limiting is
      not applicable in the SaaS sense. Performance characteristics are
      documented per Cypress/Infineon part datasheet.
  - name: GitHub Hosting
    description: >-
      Library distribution (mtb-pdl-cat1, mtb-hal-cat1, capsense,
      wifi-host-driver, btsdk-*, BSPs) is hosted on github.com/Infineon and
      subject to GitHub's platform rate limits, not an Infineon-specific
      policy.
  - name: Community Forum
    description: >-
      community.infineon.com applies forum-standard anti-abuse throttling;
      no published per-account API rate-limit table because the forum is
      browse-and-post, not a developer API surface.
