Cypress Earns USB-IF Certification for Controller

September 04, 2003 by Jeff Shepard

Cypress Semiconductor Corp. (San Jose, CA) announced it has become the first silicon vendor to achieve USB On-The-Go (OTG) compliance certification from the USB Implementers' Forum (USB-IF) for a microprocessor-based, embedded, USB OTG controller. Cypress's EZ-OTG™ (CY7C67200) controller allows portable electronic devices to communicate with one another without connecting to a PC. The (CY7C67300) device brings similar capabilities to multi-port devices like set-top boxes, point-of-sale terminals and printer servers.

Featuring a 16-bit RISC controller, large memory and low power, both the EZ-OTG and EZ-Host can operate as either a host or peripheral device, depending on the application. The devices contain 16KB of RAM, multiple CPU interfaces and on-board BIOS to handle a portion of the USB processing. The embedded processor eliminates the need for an external CPU in many applications. Based on the USB OTG protocol, the EZ-OTG enables direct connectivity between portable devices such as cellular phones, PDAs, video and still cameras, MP3 players, and mass storage peripherals.
