U3741BM-P2FL の詳細説明
Product Overview
U3741BM-P2FL from Microchip Technology is a UHF ASK/FSK remote-control receiver IC. This receiver-oriented summary is written for engineers and sourcing teams that need a clear view of the receiver function, operating band and interface requirements.
The content focuses on architecture, RF band or radio standard, power/interface characteristics and practical design notes for BOM sourcing and replacement projects.
Key Features
- Manufacturer: Microchip Technology
- Part Number: U3741BM-P2FL
- Device Type: UHF ASK/FSK remote-control receiver IC
- Receiver Architecture: LNA, VCO/PLL, crystal oscillator, IF amplifier, demodulator and control block for remote-control receivers
- Frequency Planning: Used in 315 MHz, 433 MHz, 868 MHz and 915 MHz class RKE/TPMS receiver platforms depending on device variant
- Modulation: ASK and FSK receiver support across the car-access receiver family
- Control Interface: Host-controller configuration through control pins or serial control depending on variant
- Application Class: Automotive RKE, TPMS and remote start receiver modules
- Supply Class: Designed for low-power remote-control receiver operation with polling/sleep modes in supported variants
- Package / Case: SOIC/SO package family; exact outline follows ordering code
- Design Notes: Keep crystal frequency, LNA matching and polling/sleep timing consistent with the original receiver reference design.
Applications
Automotive remote keyless entry, tire pressure monitoring, remote start and short-range command receiver modules.
Legacy car-access receiver boards where maintaining the original Atmel/Microchip receiver family and package code is important.
Quality & Sourcing
Antrex Electronics can support sourcing for U3741BM-P2FL through available stock checks, BOM consolidation and alternative-lot review. For RF receiver and radio receiver parts, package condition, lot/date code, moisture handling and original labeling should be checked before shipment.
For shortage support or legacy builds, Antrex Electronics can coordinate visual inspection, packaging verification and third-party electrical or authenticity testing when required. This helps buyers manage risk when sourcing discontinued, allocated or hard-to-find receiver ICs and modules.
