In this tradition, PLX offers the PCI 9052 I/O Accelerator. The PCI 9052 brings PLX's industry leading experience in the world of PCI designs to you in a way that is simple and convenient to use. The PCI 9052 is the ideal choice for implementation of your 32-bit, 33MHz PCI bus target (slave) I/O Accelerator designs for you 32-bit 40MHz, Industry Standard Architecture (ISA) local bus, or generic designs. 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. The PCI 9052 is a perfect fit for many networking, telecommunications, imaging, industrial, and storage applications: ■ 32-bit, 33MHz PCI operation ■ 32-bit, 40MHz local bus operation Glueless ISA interface for low cost adapters 32-bit, 16-bit, 8-bit data lines ■ ■ Local bus asynchronous to PCI clock ■ Serial EEPROM interface for loading configuration information, to simplify your switch from ISA designs ■ On-the-fly big/little endian byte conversion ■ Based on the industry-leading architecture of the PCI 9050, for easy software migration ■ – Redirects current word or byte lane during 8- or 16-bit local bus operation ■ Backwards compatibility with the PCI 9050 ■ Five local address spaces independent from EEPROM ■ Four independently programmable local chip selects ■ Up to four programmable GPIOs ■ Serial EEPROM interface – Used to switch to ISA interface mode 32-bit, 33MHz PCI Bus PCI Bus Local Bus Run-Time PCI Bus State Machines PCI Bus Interface – User-specified register initialzation values Local Bus State Machines FIFOs PCI Target (For Direct Slave Xfers) Serial EEPROM Direct Slave Read Direct Slave Write Local Master (For Direct Slave Xfers) Local Bus Interface – Dynamic Bus Width (8-, 16-, or 32-bit) – Endian Conversion – Muxed or non-Muxed Address/Data Buses 32-bit, 40MHz Local Bus Configuration Registers – ISA Logic Interface Control Logic Interrupts Direct Slave EEPROM PCI 9052 Internal Block Diagram Development Tools Support To minimize risk and lower your product development costs, PLX offers Software Development Kits (SDKs) and Rapid Development Kits (RDKs) that support the PCI 9052. These kits enable designers to quickly bring new designs to production. PLX recognizes that software often represents the largest investment in development. The PCI 9052 is fully compliant with PLX’s SDK-LITE that enables quick and easy development of high performance local processor and host PCI software through standard APIs, PCI debug tools, and sample drivers. The PCI 9052 design support is provided through RDKs that include a robust PCI development platform, complete with OrCAD schematics, documentation, a PCI 9052 chip sample, and software.
