CSRB534x

Configurable Bluetooth

dual

mode SoCs enable developers

to bring differentiated IoT

products to market quickly

The BlueCore CSRB534x series of dual-mode

SoCs (System-on-Chip) features a rich

Bluetooth v4.1 compliant platform and offers a

powerful, versatile and cost-effective solution,

making it ideal for a variety of next generation

wireless and VR (virtual reality) gaming

accessories and embedded modules.

The CSRB534x dual-mode dierentiated platform is

designed to support devices that need to connect

to both Bluetooth BR/EDR (basic rate/enhanced data

rate) and Bluetooth LE (Bluetooth low energy). These

dual-mode SoCs provide enhanced connection

topologies to improve smart device support and

accessory support. This is combined with a powerful

array of embedded system blocks including an 80MHz

processor, DSP, large I/O for sensor-rich connection,

ROM memory array, direct LED drive, and analog and

power management.

The CSRB534x highly integrated package with ultra-

low power operation allows for signicant bill of

materials (BoM) savings and optimum design exibility.

The dual-mode CSRB534x platform meets the needs

of a wide range of IoT applications including wireless

game pads, VR game pads, toys, industrial and home

automation, EPOS, data loggers, barcode readers,

metering devices and systems with large interface

requirements, such as keyboards.

Qualcomm BlueCore, CSRB5341, CSRB5342 and CSRB5348 are products of Qualcomm Technologies International, Ltd.

BlueCore™ Series

Solution Highlights

Dual-mode Bluetooth for

powerful, versatile and

cost-effective solutions

The CSRB5341 and CSRB5342 are ideal for a variety of

next generation wireless and VR gaming accessories and

controllers, HIDs and embedded modules.

Ultra-low power operation for

optimal battery life

The CSRB534x platform is Bluetooth v4.1 qualified and

makes use of a highly efficient baseband, so that system

level power consumption is minimized, giving optimized

performance with minimum development effort.

Peripheral rich for design

flexibility

The BlueCore platform comes with 22 fully configurable

digital I/O and 22 analog I/O, ensuring feature rich designs

along with embedded ROM, RAM and the option for

memory expansion with a serial Flash memory interface.

Tools for rapid development

The powerful Software Development Kit (SDK) for

CSRB534x helps accessory developers of various

operating systems to bring products to market quickly. It

includes Android and PC support and integrates SPP and

SPP over GATT.
