Epson Electronics America Announces Release of Single Chip A/V IEEE1394 Controller with Integrated PHY
SAN JOSE, Calif.--(BUSINESS WIRE)--July 8, 2003--Epson Electronics America today announced the release of the S1R72902 ASSP, an IEEE1394 chip with integrated PHY, targeted at Audio-video applications.
This single-chip 1394 IC integrates a LINK/Transaction controller ideal for IEC61883 isochronous packets, 2-port cable PHY, EPSON's S1C33000 32-bit RISC processor and a Flash ROM for the firmware. The S1R72902 includes an IDE interface and a stream interface conforming to the IEEE1394-1995 and 1394a-2000 standards.
IEC-61883 specification for consumer electronic audio/video applications has been defined to handle isochronous streaming data for audio and video over a 1394 interface. To enable IEC61883 isochronous packet transfer, S1R72902 enables automated CIP header and source packet header addition/separation. The stream interface can be connected to separate 8-bit DMA interfaces for inputs and outputs. The LINK/Transaction controller supports bi-directional data transfer in both Asynchronous and Isochronous modes.
"The advantages of this chip include the ability to switch between an IDE interface and stream interface, integration of high-precision, low-noise PHY," said Kiran Koshy, ASIC Marketing Manager at Epson Electronics America. "In developing S1R72902, Epson has leveraged its experience in having mass produced 1394 PHY products for major computer peripheral manufacturers."
Other benefits of this chip include hardware implementation of SBP2 protocol processing, taking the burden off the host processor, and a built-in 8K byte SRAM for stable data transfer up to 400Mbps. The IC also includes an ICD33 interface for easy development of firmware to run on the S1C33000 processor.
"S1R72902 is the first in the series of 1394 products designed by Epson targeted at digital audio/video applications like HDTV, set-top boxes, and home gateways. Introduction of this product broadens Epson's existing portfolio of Interface ICs targeted at computer peripherals," said George Napier, General Manager of IC Division, Epson Electronics America.
The S1R72902 is packaged in 176-pin QFP (24 x 24 x 1.4mm) and is available for mass production in July. S1R72902 costs $6.25 in volume quantities. Samples are currently available. Please contact Epson for samples and evaluation boards.
