Original LC1531 GPS BT FM device monolithic combo integrating GPS Measurement Engine , Bluetooth Low Energy and FM TX/RX BGA

Product Descriptions

The LC1531 is a monolithic combo integrating GPS Measurement Engine (ME), Bluetooth  and Bluetooth Low Energy (BLE) and FM TX/RX. It is manufactured in 45 nm CMOS  technology and provided in a WLCSP package. The CX2001 is optimized for best in class  power consumption with a very high level of integration. 

The LC1531 needs a low number of external components making integration in mobile  applications easy.

Product Features

• High co-existence and co-habitation performance with each subsystem working simultaneously at high performance

• Small dimensions: 3.80 x 4.07 x 0.6 (mm) in 85-ball WLCSP package with 0.4 mm pitch

• Minimal number of standard external components

• Shared clock and supply inputs for all functions

• Single-ended antenna ports

• Support for 1.8 V and direct Vbatt connection

• HCI commands to control all subsystems over the same shared UART interface

• System interfaces: UART, SPI, PCM, I2S, control interfaces, FM analog audio output, WLAN ePTA, and WiMAX PTA.

• Audio DSP: embedded BT wide band speech SBC codec, A2DP SBC stereo encoding and L2CAP encapsulation to reduce host 

processing and power consumption
