Cypress Semiconductor Corp. introduced a version of its CY7C67300 EZ-Host embedded USB host/peripheral controller designed for automotive applications. The device is compliant with Automotive Electronics Council Q100 specifications, featuring an operating temperature range from -40C to 85C. It is targeted at automotive infotainment applications such as interfacing MP3 players, mobile handsets and GPS systems with in-vehicle radios and display systems.

The EZ-Host device is a multi-port embedded host/peripheral controller that contains a 16bit RISC microcontroller, two configurable USB serial interface engines and a configurable I/O block that can connect to several standard interfaces. It can operate as either a host or peripheral, and supports up to four host ports. It contains 16Kbytes of RAM, enabling custom applications, multiple CPU interfaces and on-board BIOS to handle a portion of the USB processing. The embedded processor can operate in coprocessor mode.

The product's features include the following: Support for USB On-The-Go protocol; 4Kbits x 16 internal masked ROM with built-in BIOS that supports a communication-ready state with access to I2C EEPROM interface, external ROM, UART or USB; 8Kbits x 16 internal RAM for code and data buffering; extended memory interface port for external SRAM and ROM; serial port supports from 9,600 baud to 2Mbaud; and supports 12MHz external crystal or clock.

The CY7C67300 is currently available in a 100-pin TQFP package. Pricing in 1,000-unit quantities is $8.67. An automotive infotainment reference design for the EZ-Host device is expected to be available from Cypress in April 2006.
