Bluetooth module supports enhanced data rate

14 May 2008 Telecoms, Datacoms, Wireless, IoT

UniStone is a complete HCI BT 2.0 standard compliant system module which offers enhanced data rate (EDR) and excellent RF performance, among other features. The module is based on the successful BlueMoon UniCelluar IC from Infineon and it is Bluetooth qualified, FCC and R&TTE pre-approved for short time to market.

The shielded module has a small footprint of only 8,7 x 11,6 mm with 54 pads at 1,20 mm pitch and provides support for both leaded and non-leaded soldering processes. The high level of integration of the module means that the only necessary external component is the antenna. The qualified temperature range for the UniStone module is -40 to +85°C thus enabling a wide spectrum of applications in the consumer, industrial and automotive market.

The UniStone module benefits from Bluetooth power class 2 to provide long-range performance, and features adaptive frequency hopping (AFH) and packet loss concealment (PLC), a proprietary algorithm where lost packets are replaced by synthesised packets. Further benefits are integrated firmware in low cost ROM on-chip and an additional patch RAM on-chip for future enhancements and bug fixes.

The module has RF sensitivity of -88 dBm at 0,1% bit-error-rate and has adjustable UART and PCM interface levels from 1,35 V to 3,6 V. It offers extended SCO (eSCO) support, multiple SCO/eSCO links and a WLAN coexistence interface. It also includes a voltage regulator, a 26 MHz crystal oscillator, an EEPROM with unique Bluetooth device address and configuration data for initialisation, and also a balun with filter.
