1. Introduction
The HS6621CxC is a power-optimized true System-on-Chip (SOC) solution for both
Bluetooth low energy and proprietary 2.4-GHz applications. It integrates a high
performance and low power RF transceiver with Bluetooth base-band and rich peripheral
IO extension. HS6621CxC also integrates a power management to provide high-efficient
power management. The HS6621CxC is designed for operation in the world wide ISM
frequency band at 2.400 - 2.4835GHz.
The radio front end uses GFSK modulation. It has user configurable parameters like
frequency channel, output power and air data rate. HS6621CxC supports an air data rate
of 500kbps, 1Mbps and 2Mbps. The high air data rates combined with two power saving
modes make the HS6621CxC very suitable for ultra low power designs.
It targets 2.4-GHz Bluetooth low energy systems, proprietary 2.4-GHz systems,
human-Interface devices (keyboard, mouse, and remote control), sports and leisure
equipment, mobile phone accessories and consumer electronics.
