Detailed Description for BLUENRG-345AT

Product Overview

BLUENRG-345AT is a Bluetooth Low Energy wireless SoC / network processor from STMicroelectronics. It reduces the need for a separate radio IC in BLE-enabled products. It is commonly selected for BLE sensors, beacons, smart accessories, handheld devices and connected industrial products.

For design-in, continuation sourcing or repair work, engineers should review RF matching, antenna layout, interface timing, supply filtering and firmware compatibility. The selected orderable code should also be checked for package footprint, firmware or stack support, RF band, regulatory requirements and lifecycle status before approval.

Key Features

  • Manufacturer: STMicroelectronics
  • Part Number: BLUENRG-345AT
  • Device Type: Bluetooth Low Energy wireless SoC / network processor
  • Wireless / RF Technology: Bluetooth Low Energy
  • RF Band / Frequency Focus: 2.4 GHz ISM band
  • Architecture / Integration: Bluetooth LE radio and embedded control resources for compact wireless products
  • System Design Value: reduces the need for a separate radio IC in BLE-enabled products
  • Host / Peripheral Interface Review: host and peripheral interfaces should be checked against the exact BlueNRG variant
  • Security / Firmware Review: Bluetooth stack, firmware image and security resources should be reviewed before production use
  • Package / Case: 32-VFQFN Exposed Pad
  • PCB / Assembly Review: compact surface-mount IC package; confirm land pattern, thermal pad, RF keepout and assembly profile
  • Application Fit: BLE sensors, beacons, smart accessories, handheld devices and connected industrial products
  • Design Verification Notes: RF matching, antenna layout, interface timing, supply filtering and firmware compatibility

Applications

BLUENRG-345AT is commonly used in Bluetooth Low Energy products, including beacons, wireless sensors, smart locks, wearables, medical accessories, lighting controls and compact battery-powered devices.

It is especially important to review the BLE stack version, clock source, antenna matching, sleep-current profile, package footprint and firmware migration path when continuing or replacing an existing BOM.

Quality & Sourcing

Antrex Electronics can support BLUENRG-345AT sourcing with stock availability checks, RFQ quotation, date code review, package confirmation and shipment arrangement. For faster quotation, buyers can provide target quantity, acceptable date code, packaging preference, target price, required wireless protocol, frequency band, firmware or module version, and end-application information.

For quality control, Antrex Electronics can help arrange product photos, label review, visual inspection and third-party testing support when required. OEMs, EMS providers, wireless module manufacturers, IoT device makers, repair centers and electronic component buyers are welcome to send BOM lists or hard-to-find RF transceiver requirements for sourcing assistance.
