The Intel® 80219 General Purpose PCI Processor introduces a powerful combination of integrated features. It is offered in either 400 MHz or 600 MHz options. The 133 MHz PCI-X interface achieves up to 1 GB/s throughput, a two-fold increase over 66 MHz PCI. The internal bus operates at 200 MHz and offers internal bandwidth of up to 1.6 GB/s. The Intel 80219 General Purpose PCI Processor also features a 200 MHz DDR SDRAM controller with ECC that supports up to 1 GB of 64-bit DDR SDRAM. It also supports 32-bit memory for applications that are more space and cost sensitive. It contains a programmable, 32-bit local bus that is excellent for embedded applications requiring connections to non-PCI peripheral components such as ASICs, Flash memory, or DSPs.
The Intel 80219 General Purpose PCI Processor has additional features that accelerate I/O throughput. A 2-channel DMA controller facilitates increased PCI-to-memory throughput and memory-to-memory throughput. 4 KB ATU buffers and a messaging unit help maximize PCI-to-core communication.
The Intel 80219 General Purpose PCI Processor features a small 544 LPBGA (35mm) package. Additional integration includes 8 GPIO pins, 4 SDRAM output clocks, enhanced interrupt processing, a Watchdog timer, and 2 programmable timers. This integration reduces chip count, saves board space, and simplifies designs. The Intel 80219 General Purpose PCI Processor is code compatible with the 80200 processor and other Intel® XScale technology-based processors simplifying code porting from existing designs. It is compliant with the ARM* Version 5TE instruction set (excluding the floating point instruction set).
Intel® 80219 General Purpose PCI Processor opens gates of I/O throughput
The Intel 80219 General Purpose PCI Processor is based on the Intel XScale® microarchitecture. It integrates Intel® Super-Pipelined RISC Technology with a 7-stage integer, 8-stage memory superpipelined core that achieves high speed and low power. The Intel 80219 General Purpose PCI Processor is available in two speed grades: 400 MHz and 600 MHz.
The Intel 80219 General Purpose PCI Processor integrates 32 KB data and instruction caches with write-back, write-though, and hit-under-miss capabilities. These large caches greatly improve performance by preventing core stalls caused by multicycle memory accesses. In addition, a 2 KB mini-data cache is also included to help avoid "thrashing" of the data cache for frequently changing data streams.
This combination of greater core speed, larger caches, PCI-X interface, DDR memory controller, and a fast internal bus enables the Intel 80219 General Purpose PCI Processor to achieve greater data throughput. The Intel 80219 General Purpose PCI Processor can efficiently handle a broad spectrum of designs involving networking and embedded applications.
Integrated PCI-X bus and 200 MHz internal bus increase in speed and bandwidth
The Intel 80219 General Purpose PCI Processor includes an integrated 64-bit PCI-X Interface. It is fully PCI 2.2 compatible and can run at 33 MHz and 66 MHz (3.3v). The PCI-X interface (PCI-X 1.0a) can be operated at 133 MHz, (or at 100 MHz and 66 MHz) which achieves a greater than two-fold boost in performance over PCI 2.2 bus technology. The Intel 80219 General Purpose PCI Processor internal bus delivers 200 MHz speed, offering internal bandwidth of up to 1.6 GB/s, increasing performance over earlier processors with Intel XScale technology.
32-bit local bus offers increased design options
The Intel 80219 General Purpose PCI Processor offers a 32-bit local bus that provides an interface to external components that do not or can not reside on the PCI bus. It is excellent for embedded applications that need a non-PCI attach point to the processor such as ASICs, DSPs, or other peripherals. Six chip selects are available to provide expandability. The local bus functions at 8, 16, or 32 bits and is programmable at 33, 66, or 100 MHz.
200 MHz DDR SDRAM improves memory throughput
The 200 MHz DDR SDRAM memory controller acts as an interface between the Intel 80219 General Purpose PCI Processor and local system memory. It supports up to 1 GB of 64-bit DDR SDRAM, and 32-bit DDR SDRAM configurations between 32 MB and 512 MB. It also supports single-bit error correction and multi-bit detection support with ECC.
Intel® 80219 General Purpose PCI Processor offers flexibility
The Intel 80219 General Purpose PCI Processor offers the flexibility to interface with a wide variety of different technologies, including Gigabit Ethernet, USB, SATA, Graphics controllers, etc. Products that have a PCI interface can be connected to the Intel 80219 General Purpose PCI Processor. This enables the same code base to be used across multiple applications, reducing development costs and enhancing time-to-market. For more information, see the product brief.
