Murata Part Audit
Worked for 3 mins 17 sec
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.
Set pin electrical types and add datasheet-derived pin descriptions for all terminals.
Thought for 23 sec
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.
Worked for 3 mins 31 sec
Updated and verified all 77 terminals against the Murata Type 2AE datasheet:
- Assigned electrical types including Power In/Out, Input, Output, Bi-Directional, Ground, Signal, and Not Connected.
- Added concise functional descriptions with critical enable, strap, USB reference, RF, wake, and regulator details.
- No terminals remain
Unspecifiedor lack descriptions. - Existing numbering, grouping, orientation, order, and footprint mapping were preserved.

LBEE5PK2AE-564 Part Audit
Overall result
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.
- Datasheet: https://www.murata.com/products/productdata/8816428220446/type2ae.pdf
- Metadata: Pass with completeness warnings
- Symbol pin numbering and names: Pass
- 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
Metadata review
Table
| Field | Current information | Result |
|---|---|---|
| Manufacturer | Murata | Pass |
| Manufacturer part number | LBEE5PK2AE-564 | Pass |
| Product/design | Type 2AE wireless module | Pass |
| Package/case | Module | Valid but overly broad |
| Mount | Surface mount | Pass |
| Description | Wi-Fi/Bluetooth transceiver module | Pass |
| Datasheet URL | Official Murata Type 2AE PDF | Pass; unchanged |
| Terminal count | 77 | Pass |
| Footprint pad count | 77 | Pass |
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.
Pin accounting
- Ground: pins 1, 14, 16, 21, 23, 24, 27, 34, 41, 57, 69–77 — 19 total
- No-connect: pins 15, 35–40, 44, 58–62 — 13 total
- External RF port: pin 22, WL_ANT
- 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_VLXrequires the specified regulator inductor/capacitor network. WL_REG_ENandBT_REG_ENinclude default 200 kΩ internal pull-downs.- Pin 50
USB2_RREFrequires 4.75 kΩ ±1% for USB operation and is DNI for SDIO operation. JTAG_SELmay be NC/GND when unused and must be high for JTAG/SWD.USB2_AVDD33connection depends on the VBAT configuration.
- Pin 2
- 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_ANTas 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.
Key specifications
- Wi-Fi: IEEE 802.11a/b/g/n/ac, 1×1, up to 433 Mbps
- Bluetooth: Bluetooth 5.2 BR/EDR/LE
- WLAN host interface: SDIO or USB
- Bluetooth host interface: UART or USB
- RF bands: 2.4 GHz and 5 GHz, external antenna connection
- Recommended VBAT: 3.13–3.50 V, 3.3 V typical
- VDDIO: 1.62–1.98 V at 1.8 V nominal, or 2.97–3.63 V at 3.3 V nominal
- Absolute maximum VBAT: −0.5 to 5.5 V
- Absolute maximum VDDIO: −0.5 to 3.9 V
- Operating temperature: −40 to +85 °C
- Storage temperature: −40 to +85 °C
- Reflow: example peak 240–250 °C, never above 260 °C, maximum two reflows
- Cleaning is not permitted; observe moisture-sensitivity handling requirements.
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.
