Cypress Semiconductor recently introduced its next-generation 2.4GHz radio-on-a-chip (RoC) that enables low bill of materials (BOM) cost, higher data rate applications and faster time-to-market schedules for Human Interface Devices (HIDs) applications. In addition, the company debuted a USB 2.0 programmable microcontroller in a 56-ball VFBGA (Very Fine Pitch Ball Grid Array) package, which measures only 5×5mm with a 0.5-mm ball pitch, for implementing high-speed USB in small-form-factor or battery-powered applications such as mobile phones, portable media players, PDAs and webcams.

The WirelessUSB LP RoC operates between 1.8 and 3.6 volts and uses Cypress' patented Direct Sequence Spread Spectrum (DSSS) and frequency-agile technology to offer best-in-class interference immunity for a 2.4GHz radio system. WirelessUSB LP brings these benefits to the Voice over IP (VoIP) market for products like wireless headsets by transferring data at a maximum speed of up to 1Mbps.

With Cypress's patent pending AutoRate Receiver technology, the WirelessUSB LP can receive data at any data rate without the need to negotiate speed changes. In addition, the device includes integrated features such as an automatic transaction sequencer, deep packet buffers (16 byte) for TX and RX and a boost converter (generating up to 2.7V).

Cypress is sampling the WirelessUSB LP now in 40-pin QFN packages. Full production quantities are expected to be available in the first quarter 2006. Pricing is approximately US$1.20 each in high volumes.

The EZ-USB LP microcontroller family takes advantage of advanced process technology developed by Cypress to slash dynamic and standby power consumption by nearly 50%. Peripherals using the new devices can operate from the power of the USB bus and the low standby current enables portable USB applications to significantly extend battery life.

The EZ-USB FX2LP has typical current consumption of just 50mA, enabling peripherals to enumerate at well below the 100mA USB-IF bus power specification to offer ample power margins to implement additional features. Competing solutions typically consume 80-110mA. The device is a fully integrated peripheral controller, including an 8051 microprocessor, a serial interface engine, a high-speed USB 2.0 transceiver, on-chip RAM and FIFO and a general programmable interface. The new microcontroller features 480Mbps in data rate, 16Kbytes of on-chip memory and up to 40 programmable I/Os.

In addition to the 56-ball VFBGA, the EZ-USB FX2LP is offered in 100- and 128-pin TQFP and 56-pin QFN and SSOP packages. Pricing in high volumes for the EZ-USB FX2LP starts at as low as US$2.95.
