Package dimensions and footprint requirements

Package: 64 LFBGA (7 × 7 mm)
Mechanical: LFBGA (7 × 7 × 1.4 mm), 8 × 8 array, ball pitch 0.8 mm, ball diameter 0.4 mm
Recommended PCB footprint/land pattern: per LFBGA-64, 0.8 mm pitch guidance in the datasheet

Cross-check: symbol and footprint vs datasheet

Findings

Pin count and naming:
- Symbol has 64 terminals arranged A1–H8, consistent with the 64-ball BGA.
- Pin names closely match datasheet conventions (power nets use numeric suffixes where duplicated, e.g., VDD33_TX_1/2).
- Critical mismatch found:
  - Datasheet G8 is VDD12ON (3.3 V output, power control). In the symbol, G8 is labeled NC. This is incorrect and could lead to missed functionality or wiring error. Recommend renaming to VDD12ON and marking as an output per datasheet guidance.
Grounds/powers:
- 9 ground balls present; symbol shows GND_1 through GND_9. Count aligns with the datasheet’s B3, B6, D4, D5, E4, E5, G3, G6, D8.
- Duplicated power balls (e.g., VDD33_RX, VDD12_RX, VDD33_IO, VDD12_DIG, VDD33_TX, VDD12_TX) are correctly represented as suffixed pairs.
Package property:
- Project property “Package or Case Code” is set to “TO” but the datasheet specifies 64 LFBGA (7 × 7 mm), pitch 0.8 mm, ball 0.4 mm. This mismatch can cause ordering/manufacturing confusion. Recommend updating the package/case property to LFBGA-64, 7 × 7 mm, 0.8 mm pitch.
Footprint:
- Pad count and pad names in the footprint match the 64-ball map (A1–H8, names consistent).
- Unable to verify exact ball pitch, ball size, and overall body dimensions from the layout data returned. Please ensure the footprint implements:
  - 8 × 8 grid, pitch 0.8 mm
  - Ball diameter 0.4 mm
  - Body size 7 × 7 mm
  - Solder mask/paste apertures per datasheet recommendations
- Confirm special pins’ layout considerations (e.g., keepouts/guarding on DP lanes, crystal pins E8/TCLK routing to 27 MHz XTAL, dedicated decoupling for C_EXT/F7) as you proceed with board design.

If you want, I can:

Rename G8 from NC to VDD12ON and set its pin type to Output.
Update the part’s package/case property to the correct LFBGA-64 (7 × 7 mm, 0.8 mm pitch).
Verify footprint geometry (pitch/ball/body) if you share or enable detailed footprint dimensions.

Run DRC/ERC review
