Cypress lancerer ny generation af WirelessUSB transceivere

Nye low-power 2,4 GHz Wireless USB transceivere leveres i en bred vifte af pakningstyper - herunder også som 'bare dies' (in english).

Cypress Semiconductor has introduced its next-generation 2.4-GHz WirelessUSB 'Radio-on-a-Chip'. The new WirelessUSB NL gives manufacturers a robust performance along with very low power consumption for wireless keyboards, mice, remote controls and other Human Interface Devices (HIDs). The new devices are offered in 4 x 4 mm QFN packages, in bare die, and in wafer form, enabling low-cost chip-on-board manufacturing.

WirelessUSB NL boasts an impressive -87dBm receive sensitivity at 1 Mbps. This enhanced sensitivity enables longer range operation and allows for lower-power transmit signals.


The device features very low active and standby current (less than 1 uA), enabling battery life to be more than a year for normal mouse usage. WirelessUSB NL also has a closed-loop internal architecture that minimizes signal frequency drift for very robust radio performance. This robustness minimizes retries during transmission enabling lower power consumption and allows for long payload lengths of up to 255 bytes.

As with other Cypress WirelessUSB families, the NL device offers superior performance in the presence of common 2.4-GHz interference from sources such as WiFi, Bluetooth, cordless phones and microwaves. The device is highly integrated, requiring less than 12 non-critical supporting components to make a complete mouse.

This integration reduces board space, BOM cost and manufacturing cost, while improving overall product quality.
