I’ll organize all 77 terminals into broad datasheet-based functional groups, keep Section equal to Pin Group, apply consistent group orientations, and assign Power first and Ground last.
Organized and verified all 77 terminals across nine functional groups. Section matches Pin Group throughout; Power is Top/order 1, Ground is Bottom/order 10, and Bluetooth, WLAN/SDIO, USB, GPIO, RF, debug, and NC groups use consistent Left/Right orientations and ordering.
Open item
Pin electrical types remain Unspecified; they were outside this requested edit.
I’ll map every terminal’s electrical type from the Murata pin table, add concise datasheet-derived descriptions, then verify all 77 pins without changing their numbering or grouping.
The part is electrically and mechanically identifiable as Murata Type 2AE, ordering part number LBEE5PK2AE-564, based on the Infineon CYW4373E. The existing Datasheet URL is already the official Murata PDF and therefore was not changed.
Terminal types, descriptions, and functional grouping: Fail / incomplete
Footprint pad mapping and nominal geometry: Pass
Paste/mask aperture details: Ambiguous because the manufacturer drawing does not state explicit reductions/expansions

Optional metadata not populated includes a product-page URL, module dimensions, operating voltage, temperature range, RF output/interface details, lifecycle, and reference/application-note URLs. The package description could be more specific: shielded resin SMT module, 8.00 × 7.80 × 1.15 mm maximum height.
Symbol and pin audit
All terminal numbers 1 through 77 exist exactly once. No missing or duplicate pin numbers were identified. Terminal names align with the Murata pin table; differences are limited to identifier formatting such as underscores replacing spaces.
Remaining pins cover power, SDIO, USB 2.0, Bluetooth UART/PCM, GPIO, wake, RF switch control, debug, and strap functions.
Mismatches and incomplete fields
All 77 terminals have Pin Type = Unspecified. The datasheet explicitly distinguishes power input/output, RF, input, output, and bidirectional functions.
Pin Description is absent on every terminal. Important omitted instructions include:
Pin 2 SR_VLX requires the specified regulator inductor/capacitor network.
WL_REG_EN and BT_REG_EN include default 200 kΩ internal pull-downs.
Pin 50 USB2_RREF requires 4.75 kΩ ±1% for USB operation and is DNI for SDIO operation.
JTAG_SEL may be NC/GND when unused and must be high for JTAG/SWD.
USB2_AVDD33 connection depends on the VBAT configuration.
Pin Group and Section metadata are absent. Recommended broad groups are Power, Ground, WLAN/SDIO, Bluetooth UART/PCM, USB, RF, GPIO/Wake, Debug/Strap, and NC, with each pin assigned to only one group.
The symbol is a long two-sided pin list rather than a functionally organized symbol. This is a readability issue, not a pin-mapping error.
Footprint audit
The footprint contains exactly 77 numbered SMD pads, numbered 1–77, and every symbol terminal has a matching pad.
Verified nominal features:
Body outline: 8.0 × 7.8 mm, consistent with the Murata outline of 8.00 ±0.20 mm by 7.80 ±0.20 mm
Maximum module height: 1.15 mm
Pad size: 0.30 × 0.45 mm
Peripheral/inner-row pitch: 0.60 mm
Central ground array: 1.00 mm grid
Numbering pattern:
1–12 bottom edge
13–22 right edge
23–34 top edge
35–44 left edge
45–68 inner ring
69–77 center ground array
Pin-1 orientation is coherent with the footprint marker.
Ground pins 69–77 are correctly represented as nine individual pads; there is no additional monolithic exposed-pad number in the manufacturer pinout.
A 3D STEP model is present.
Footprint observations
Copper, paste, and mask are enabled on every pad with nominally matching apertures. The Murata land-pattern drawing does not explicitly define paste reduction or solder-mask expansion, so those manufacturing details cannot be conclusively validated from the available document.
NC pads are retained, consistent with the full land pattern. Murata warns that NC-land formation can affect characteristics; do not remove or repurpose them casually.
The pin-1 silkscreen marker is small and may be marginal after normal fabrication, although orientation remains identifiable.
The courtyard is approximately 10.0 × 9.8 mm. It is conservative and not contradicted by the module outline.
RF and antenna constraints
Type 2AE has no integrated antenna. Pin 22 is an external 50 Ω RF port, so a fixed antenna keepout should not be embedded in this reusable footprint. Apply the actual RF geometry and keepout at the host-board level after selecting the antenna configuration, stackup, placement, and certified reference arrangement.
Host-board requirements include:
Route WL_ANT as a controlled 50 Ω RF line.
Follow Murata's stackup-dependent RF trace and antenna guidance.
Murata calls for RF trace-width accuracy of approximately ±0.025 mm.
The Murata reference trace-antenna guidance uses approximately a 40 × 40 mm or larger host board, 20 mm metal/ground clearance around the antenna region, and 4 mm dielectric clearance.
Connector-based antenna implementations need connector-specific keepouts and an approved/equivalent antenna configuration.

Recommended corrections
Populate Pin Type for all 77 terminals from the Murata pin table.
Add datasheet-derived Pin Description text, especially for power, enable, USB reference, strap/debug, NC, and RF pins.
Add broad, exclusive Pin Group and Section classifications for symbol readability.
Consider enriching metadata with exact dimensions, operating ranges, product URL, and application/reference-design links.
Keep antenna geometry and keepout configuration at the host-board level rather than making the reusable footprint configuration-specific.
