SX1441

Ultra Low Power Bluetooth® V1.2 Soc for Wireless

Headset and Data Applications with DSP Capabilities

GENERAL DESCRIPTION

The SX1441 is a Bluetooth

includes a fully programmable 8-bit application

microcontroller, a high speed UART, SPI interface,

RC oscillator, power management unit, and an on-

chip voice CODEC with DMA interface. The purpose

of the SX1441 is to offer a very high level of

integration

components to build complete voice and data

applications whilst maintaining design flexibility.

This product has been designed for ultra low power

consumption and low cost solutions. By combining

the SX1441 with a low power 2.4 GHz radio device

such as the XE1413, from Semtech, an ultra low

power Bluetooth wireless headset consuming less

than 23mW @1.8V (HV3) can be built.
