Low-Power 2.4-GHz WirelessUSB-NL Solution chosen for Wireless Mouse and Keyboard Set
Cypress has today revealed that Lite-On has selected Cypress’s 2.4-GHz WirelessUSB-NL radio-on-a-chip for its next-generation wireless keyboard and mouse set. WirelessUSB-NL’s low power consumption enables two AA batteries to power the mouse and keyboard for up to three years. The long range of WirelessUSB-NL also enables the wireless mouse and keyboard set to operate at a distance of up to 30 meters.
LiteWirelessUSB-NL (CYRF8935) boasts an impressive -87 dBm receive sensitivity to enable longer range operations. The device features very low active and standby current (less than 1 uA), and has a closed-loop radio architecture that minimizes signal frequency drift for very robust radio performance. As with other Cypress WirelessUSB families, the WirelessUSB-NL device offers superior performance in the presence of common interference from 2.4-GHz sources such as WiFi, Bluetooth, cordless phones and microwaves.
“We are pleased to see the launch of Lite-On’s ground breaking mouse and keyboard set,” said Jayant Somani, senior director of worldwide marketing for Cypress’s Data Communication Division. “With industry-leading battery life, long-range operation, and the superior noise immunity of Cypress’s Wireless USB, Lite-On has set a new benchmark for performance.”
“Cypress provided a total solution with high performance and best-in-class immunity to RF interference,” said Jerry Lee, Manager of Wireless Technology Design in Human Input Solution SBU of Lite-On. “Cypress also provides excellent technical support, accompanying enCoRe microcontrollers, and outstanding reference designs.”
WirelessUSB-NL is complemented by Cypress’ enCoRe II and enCoRe V low-voltage, highly integrated microcontrollers, offering manufacturers a single source of supply and support. WirelessUSB-NL also supports Cypress’ Agile HID protocol that allows existing WirelessUSB customers to get started quickly on their designs without any additional effort.
WirelessUSB delivers the best combination of performance and cost versus competing wireless technologies. Featuring a highly integrated radio transceiver plus digital baseband on a single chip, WirelessUSB enables designers to significantly decrease development time, component count and system cost while improving operating range, power-consumption and latency.
