The PCE335 Intelligent Synchronous Serial Communications Adapter provides four high-performance synchronous serial ports for connectivity. The adapter is ideally suited for use within radar servers, frame relay access devices, high-speed modems, and other high-speed communications devices. It is part of Sunhillo’s industry-leading Protocol Software and connectivity solutions.
It is designed as a fully programmable communications subsystem capable of sustaining high data rates for a variety of protocols used in synchronous data communications. Its architecture capitalises on the intelligence of the Freescale™ MPC8270 Quad Integrated Communications Controller (PowerQUICC® II), enabling it to act as a specialised communications controller. It enhances overall system performance by using its on-board intelligence and 128 MB of SDRAM array to handle much of the low-level communications that typically burden the host system, and relegates most of the serial I/O communication-related processing to the PCE335. In addition, the SDRAM eliminates start-up delays associated with application download wait times by enabling the code to be executed directly on-board.
