Programmable Radio-on-a-Chip™ melds two technologies — WirelessUSB and PSoC.

Cypress Semiconductor introduces its 2.4 GHz Radio-on-a-Chip with a programmable mixed signal array. The Programmable Radio-on-a-Chip™ (PRoC™) includes two of the company's technologies — WirelessUSB™ and Programmable System-on-Chip™ (PSoC™) — in one integrated device. It delivers the benefits of both technologies into a variety of applications, including consumer electronics, home and industrial automation, Human Interface Device (HID), transportation, security and medical systems.

WirelessUSB features a highly integrated radio transceiver plus digital baseband on a single chip. The technology enables designers to significantly decrease development time, component count and system cost while improving operating range, power consumption and latency. The DSSS (Direct Sequence Spread Spectrum)-based technology is robust to interference and features a range of up to 50 meters and beyond.

PSoC devices are configurable mixed signal arrays that integrate a fast 8-bit microcontroller with many peripheral functions typically found in an embedded design. PSoC devices provide the advantages of an ASIC without the ASIC NRE or turnaround time. A single PSoC device can integrate as many as 100 peripheral functions with a microcontroller. Easy to use development tools enable designers to select configurable library elements to provide analog functions such as amplifiers, ADCs, DACs, filters and comparators, and digital functions such as timers, counters, PWMs, SPI and UARTs. The PSoC family's analog features include rail-to-rail inputs, programmable gain amplifiers and up to 14-bit ADCs with exceptionally low noise, input leakage and voltage offset. PSoC devices include up to 32 kB of Flash memory, 2 kB of SRAM, an 8 × 8 multiplier with 32-bit accumulator, power and sleep monitoring circuits and hardware I2C communications.

The PRoC device is part of a portfolio of devices that combine WirelessUSB technology with Cypress controller solutions. PRoC offers access to a general-purpose mixed signal array with four programmable analog and four programmable digital blocks, 8 kB of Flash program memory storage, 512 B of SRAM data storage, and a powerful DSSS 2.4 GHz radio system — all integrated in a compact package. It is designed to implement highly integrated, wireless systems operating in the worldwide 2.4 GHz ISM band.

Cypress is sampling the CYWUSB6953 today in 48-pin QFN packages. Full production quantities are expected to be available in Q3, 2005. Pricing is approximately $3.50 each depending on quantities.
