Summary

ams-OSRAM USA INC. AS3955-AWLM-I4 is evaluated in RFID, RF Access, Monitoring ICs category when frequency coverage and integration details must hold up in the real enclosure. Key specs include Description (IC RFID TRANSP 13.58MHZ 12WLCSP), Temperature (-40°C ~ 125°C), Package/case (12-UFBGA, WLCSP), Mounting (Surface Mount), and Packaging (Tape & Reel (TR)).

Selection Notes
  • For AS3955-AWLM-I4, double-check the mounting type (Surface Mount) for your intended installation method.
  • Make sure your rails cover (1.65V ~ 5.5V) across temperature and load, with adequate margin.
  • Double-check the data interface (I2C) for integration and verification planning.
Alternates & Substitutions
  • In RFID, RF Access, Monitoring ICs, confirm that alternates preserve startup states and fault behavior so system behavior does not change quietly.
  • Confirm the physical match (package/case 12-UFBGA, WLCSP, supplier package 12-WLCSP (2.13x1.42), mounting Surface Mount) and the operating corners (supply 1.65V ~ 5.5V, temperature -40°C ~ 125°C) so the substitution is not a hidden redesign.
  • For RF substitutions, match the operating band and interface, then validate insertion loss and return loss in your real signal path.
  • If substitutions are likely, write down the non-negotiables and re-check them when the supply chain changes, not after field failures.
FAQ

Any tips for integrating AS3955-AWLM-I4 into an RF signal path?
Pay attention to impedance continuity, grounding, connector transitions, and layout symmetry to minimize loss and reflections.

Which operating frequency is specified for AS3955-AWLM-I4?
13.58MHz

Which Supplier Device Package is listed for AS3955-AWLM-I4?
12-WLCSP (2.13x1.42)

What is the operating temperature range of AS3955-AWLM-I4?
-40°C ~ 125°C

Application Scenarios

When ams-OSRAM USA INC. AS3955-AWLM-I4 is used in RFID, RF Access, Monitoring ICs designs, teams typically start by confirming interfaces, supply rails, operating envelope, and qualification expectations. RF parts are judged by how they behave on the board: impedance environment, coupling, shielding, and the real antenna or load. Minor layout differences can shift spurs and margins, so evaluation includes grounding, stack-up, shielding, and test access from day one. In medical telemetry, controlled emissions and stable links are prioritized around sensitive instruments. Across industrial handheld radios, RF robustness is validated under shock and battery sag because enclosure effects and supply droop change margins. In real deployments, across rugged handhelds, stability under vibration and low battery conditions is treated as a primary constraint for RF qualification. The end result is more predictable performance, faster troubleshooting, and fewer surprises during production ramp.

Compatibility Advice
  • In board-level integration, confirm power supply isolation so conducted noise does not translate into emissions or desense in real deployments. This helps field behavior stay predictable across lots.
Project Fit
  • Ideal when you can validate ams-OSRAM USA INC. AS3955-AWLM-I4 for RFID, RF Access, Monitoring ICs integration with the real wiring and cabling, typically when you have a defined frequency plan and filtering strategy from the start. That said, riskier when integrating ams-OSRAM USA INC. AS3955-AWLM-I4 for RFID, RF Access, Monitoring ICs, impedance and return paths cannot be maintained through the connector system, because integration risk stays high when key margins cannot be measured.
