First ‘USB On-The-Go’ embedded controller launched

Supplier News

Cypress Semiconductor (distributed by Braemac ) claims to be the first silicon vendor to achieve USB “On-The-Go” (OTG) compliance certification from the USB Implementers’ Forum for a microprocessor-based embedded USB OTG controller. (See EDN Australia July 03 page 16.)

Cypress’ EZ-OTG controller allows portable electronic devices to communicate with one another without connecting to a PC. A sister EZ-Host device is said to bring similar capabilities to multi-port devices including set top boxes, point-of-sale terminals and printer servers.

Both devices can operate as either a host or peripheral device, depending on the application and have an embedded 16 bit RISC processor that eliminates the need for an external processor in many applications.

Being based upon the USB OTG protocol enables direct connectivity between compatible portable devices, such as cell phones, PDAs, video and still cameras, MP3 players and mass storage peripherals.

The USB Implementers Forum is a non-profit corporation founded by the same group of companies that developed the USB specification. It both promotes and defines protocol standards for USB-related applications and products.
