CP2112-F02-GMR

CP2112-F02-GMR is a USB device controller in the F02 series of the CP2112 family, providing a single-chip solution for USB operations. It is integrated with a 2.4GHz frequency-hopping spread spectrum (FHSS) transceiver, a UART, and several GPIOs with an array of on-board signal conditioning. This device is designed to make usage of the USB interface in portable applications that require enhanced screening and radio communication.

Application Field

The CP2112-F02-GMR is an ideal controller for a variety of applications, such as personal monitoring and metering applications, medical device control, remote controls for consumer products and industrial automation, traffic signaling, and home security systems. This controller is designed to meet the needs of products requiring low data rates and secure RF transmissions. It also provides a very low power USB as well as a battery back-up/recharge option through the USB interface.

Working Principle

CP2112-F02-GMR is a USB-powered controller that utilizes energy efficient Cypress FHSS 2.4GHz transceiver technology. The integrated FHSS transceiver allows data communication in the 2.4GHz ISM band, enabling the most reliable device data transmission at the lowest possible power output. Through the UART, the controller acts as an intermediary between the RF software and the USB interface, allowing the transfer and reception of data. The controller also enables USB communication with peripheral devices, such as printers, and peripherals for RF communication.

The device can be configured to run in either master and slave mode, depending on the application. In combined mode, data is both transmitted and received over the USB interface, while data is only transmitted in master mode. Its I/O function connect to several IO ports, such as GPIO, SPI and I2C, to allow for the configuration of the controller to both the user side and the attached peripheral. The IC also provides standby and wake-on-interrupt functions, allowing the controller to turn off power-hungry peripherals or even the entire system when not in use and to pull them back up when they are needed. GPIO pins can be also used to control backlighting, LCDs and electric curtains as an input source or source of data.

The Cypress FHSS technology allows for a single-chip solution for low data rate USB applications requiring secure, low power radio transmissions. The CP2112-F02-GMR can provide a complete USB controller and RF transceiver, making it an ideal choice for wireless embedded systems and portable devices needing a wireless connection.
