Baja4700E Heurikon Single Board Computer

Targeting compute and I/O intensive applications like communications, imaging, embedded control, and video-on-demand, the Emerson / Heurikon Baja 4700 VME Single Board Computer features a 64-bit VME64 interface, on-card Ethernet, two serial ports and up to 64 Mbytes of DRAM. It also features a pair of 32-bit PMC expansion interfaces, which make it easy for designers to add custom and off-the-shelf third-party PMC cards.

The Baja's compute engine is IDT's R4700, available in both 166 and 175 MHz versions. The 166 MHz board is optimized for high-performance I/O, and is best suited for I/O intensive applications. The 175 MHz board is best suited for CPU intensive applications such as those requiring extensive floating point calculations or critical program loops.

The Baja's PMC (PCI Mezzanine Card) interface features two 32-bit expansion connectors. The two interfaces can accept either two single-wide or one double-wide module. I/O can be routed either to the front panel or out the P2 connector. Because it supports two PMC modules, the Baja is ideally suited to communications applications requiring support for multiple protocols. By mixing PMC modules the Baja can serve as a high-performance bridge between networks. The excellent data moving capabilities of the R4700 processor make the board ideal as a communication switch controller, and the 2 PMC slots ensure compatibility with most standard or custom switch interfaces.
