Add Target Functionality with Ease
- The PCI 9052 has the industry's most flexible local bus, which allows for multiple interface options to a wide variety of memory and I/O devices. Combine that with fully tested, PCI r2.1 compliance, and your design risk is virtually zero. The PCI 9052 has a set of advanced features to provide high performance and flexibility in order to simplify your design, such as four programmable GPIOs, local chip select, prefetch read ahead mode, zero wait state bursting, and on-the-fly big/little endian byte conversion.
Move your ISA Designs Up to Leading PCI Capabilities with Ease
- The PCI 9052 accelerates I/O data movement on adapter boards, from ISA’s nominal bus speed of 8MHz, 5MBytes/second, to high-performance 33MHz, 132Mbytes/second PCI data transfer. The PCI 9052 enables a simple, rapid, low cost conversion of ISA adapters to the PCI.
