Texas Instruments and Cypress Semiconductor introduced a power-optimized wireless mouse reference design kit with a 27-MHz dual-channel receiver. The receiver system incorporates TI’s TRF7900 dual-channel receiver and a Cypress microcontroller (CY7C63743) to receive the transmit information from the mouse, decode it and communicate the mouse movements and switch selections to the personal computer via a Universal Serial Bus interface.

The mouse design optimizes power consumption and maximizes battery life using a low-power optical mouse sensor (ADNS3040) from Agilent Technologies and TI´s MCU MSP430F1222. The MSP430 MCU’s features a typical real time clock standby current of 0.7 micro-amps and a shut-down mode of 0.1 micro-amps.

The 27-MHz Wireless Receiver and Mouse EVM and Reference Design (MSP-TRF7900-EVM) including mouse, component samples and CD-ROM with complete code, bill of materials and technical documents is available now, priced at $199 per kit.
