UC1394a-3 (Legacy *)

Multi-Chip Module

* Legacy Product: Available, but Not Recommended for new designs.

The ultra-compact UC1394a-3 is the second in a series of ready-to-use embedded FireWire peripheral interface devices for integrating digital hardware, such as cameras, sensors, and other embedded devices, within a high performance FireWire networking environment. It is implemented as a 116 pin PLCC surface mount multi-chip module, which measures only 30mm x 36mm.


On-board DSP, FPGA and a wide variety of serial and configurable digital I/O resources provide the developer with an extensive range of plug & play and software programmable capabilities for IEEE 1394 FireWire connectivity, embedded peripheral control, and signal processing applications.

Key functional resources within the UC1394a-3 include a TMS320C5501/2 DSP, a Xilinx Spartan-3 50k/200k Gate FPGA, TSB12LV32 Link Layer and TSB41AB2 Physical Layer [IEEE 1394a] controllers. 4MBytes of SDRAM and 512kBytes of FLASH ROM provides program and data storage for the DSP and FPGA.

UC1394a-1 FireWire Interface and DSP Module

Two 400MBit/s IEEE 1394a ports are provided, together with a wide variety of universal interfaces to enable integration with a hardware design. These include a 32MByte/s 16-bit wide plug & play data streaming interface, RS-232, McBSP, I2C, JTAG, and user configurable digital I/O. All of the interfaces are accessed via the PLCC pin connectors.
