CSRB5348A11-IBVE-R

RF Transceiver ICS Overview

The CSRB5348A11-IBVE-R is a Bluetooth dual-mode System-on-Chip from the Qualcomm CSRB5348 family, compliant with Bluetooth 4.1 specifications. It integrates an RF transceiver and MCU within a 105-VFBGA package. The device supports Bluetooth Low Energy and Classic modes with a maximum output power of up to 9 dBm and receiver sensitivity down to -90 dBm at Basic Rate. Internal memory includes 8 Mb ROM and 56 kB RAM, while the CPU operates at speeds up to 80 MHz.

RF Transceiver ICS Feature Summary

• Dual-mode Bluetooth connectivity supporting both Bluetooth Low Energy and Classic protocols
• High-end industrial temperature grade platform suitable for demanding environments
• Integrated Li-Ion battery charger capability for portable applications
• Rich peripheral interface including 22 digital I/Os and 22 analog I/Os

RF Transceiver ICS Applications

• Wireless gaming accessories and controllers
• HID (Human Interface Device) implementations
• Embedded modules for IoT systems

RF Transceiver ICS Procurement Notes

Verify that the specific suffix IBVE-R corresponds to the required industrial temperature range and packaging configuration. Confirm that the 105-VFBGA package dimensions align with the target PCB layout. Ensure compatibility with the host system's voltage requirements, noting the maximum input voltage specification. Cross-reference the Bluetooth 4.1 compliance against current regulatory standards for the intended market deployment.

RF Transceiver ICS Selection Notes

Select this component when designing wireless gaming peripherals or embedded IoT modules requiring dual-mode Bluetooth support. The industrial temperature rating makes it suitable for harsher operating conditions compared to standard consumer grades. Consider the integrated charger and rich I/O options if minimizing external component count is a priority. Evaluate the 80 MHz CPU speed against application processing requirements before finalizing the design.

RF Transceiver ICS Part Context

This part belongs to the CSRB5348 family of turnkey System-on-Chips designed for wireless gaming and IoT applications. The family emphasizes BoM savings and rapid development through high integration. Unlike broader automotive or high-performance computing SoCs, this series focuses on cost-effective, ultra-low power solutions for connected accessories and embedded sensors.

RF Transceiver ICS Replacement Considerations

Public documentation indicates that older chipsets like the CSR8811 are being replaced by newer platforms such as the Snapdragon S3 Gen 1 Sound Platform. However, direct pin-to-pin substitutes for the CSRB5348A11-IBVE-R are not explicitly confirmed in available public data. Designers should verify functional equivalence if migrating to other Bluetooth SoCs.
