Application Field

CY8C4127LQI-BL473 is a very cost-effective solution for short-range wireless communications, low-power Bluetooth Low Energy (also known as Bluetooth Smart) applications and associated networks. The integrated features of the IC make it suitable for applications such as: wireless audio, locks and monitors, wireless sensor networks, home appliances, automotive infotainment, wireless payment and access control.

The flexibility of the IC also enables it to be used in a wide variety of other applications including: consumer electronics, medical devices, Internet of Things (IoT) devices, industrial automation and wearables.

Working Principle

CY8C4127LQI-BL473 is a Transceiver that enables the transmission and reception of data using RF signals. The IC utilizes an integrated radio frequency (RF) transceiver, baseband polling system, power management system and other components to support long-distance data transmission or acquisition. Primarily, the transceiver functions as Radio Link Controller (RLC) that coordinates between the two endpoints of a link.

When the IC receives a transmission from one end-point, it transmits the data to the other end-point. This is known as an uplink. Conversely, when the IC receives a transmission from the other end-point, it transmits the data back to the first end-point. This is known as a downlink. The IC is also capable of performing in both receive-only and transmit-only modes.

In terms of power efficiency, the IC has the ability to automatically adjust its power output depending on the distance between the two end-points. Additionally, the IC features various frequency selective tracking functions, enabling it to work on various frequency bands. The IC also features modulation techniques such as BPSK, Q PSK, and OOK.

Conclusion

CY8C4127LQI-BL473 is a versatile transceiver IC, mainly used in short-range wireless communications, such as Bluetooth Low Energy (BLE) applications and associated networks. The integrated RF transceiver, baseband protocol support and two on-chip antennas provide a cost-effective solution for these applications. In addition, the IC also has the ability to perform various frequency selective tracking functions and modulation techniques, making it suitable for a wide variety of applications.
