SAN JOSE -- Cypress Semiconductor Corp. here has introduced an evaluation kit for its keyboard plus integrated four-port hub USB controller.
The kit (CY3652-KBHUB) uses the Cypress single-chip solution, CY7C66113, for the USB keyboard and hub function. Cypress reported that its one-chip solution significantly reduces overall system cost versus comparable solutions by enabling keyboard designers to immediately connect the fully functional hardware right out of the box, and begin evaluation of the Cypress design.
The evaluation kit includes full reference design files, including source code, an application note, schematics in Orcad and .pdf formats, an Orcad OPJ file, a bill of materials, and a Cypress CY7C66113 datasheet.
While competing solutions require external EEPROM for programming flexibility and provide only two downstream ports, the Cypress kit has the EPROM inside the CY7C66113, enabling manufacturers to quickly change the keyboard matrix for different multimedia keyboards while reducing both the bill of materials and overall cost for system designers, said Allyn Pon, product marketing director for Cypress USB.
Cypress also offers the CY3652C Development Kit, which uses real-time hardware emulation of the actual devices to assist in firmware development. The kits consist of a USB development board, USB monitor/debugger, assembler, example application source code, cables, and documentation.
