Tsi382A PCI Express to PCI Bridge The Tundra Semiconductor Tsi382A is a high-performance bus bridge that Features connects PCI Express based devices to legacy PCI devices. The Tsi382As General PCIe Interface supports a x1 lane configuration, which enables the bridge to PCI Express 1.1 to PCI bridge offer throughput performance of up to 2.5 Gbps per transmit and receive direction. Transparent and Non-transparent addressing modes The devices PCI Interface operates up to 66 MHz, and supports transparent Efficient queuing and buffering for low and non-transparent addressing. The Tsi382A supports Legacy mode latency and high throughput operation, which configures the device as a subtractive decode PCIe-to-PCI bridge. Legacy mode support for subtractive decode Block Diagram Compliant with the following specifications: PCI Express Base 1.1 Clocking/ EEPROM PCIe Interface (x1) Reset Controller PCI Express PCI/PCI-X Bridge 1.0 PCI-to-PCI Bridge Architecture 1.2 PCI Local Bus 3.0 PCI Bus Power Mgt.

The device is offered in a 10 x 10 mm package with a Up to eight outstanding memory reads standard 0.8-mm ball pitch, making it ideal for PCI ExpressCard applications PCI clock outputs for up to four devices or similar designs that have limited component space. For cost-sensitive Four external PCI masters supported applications, the Tsi382A is also available in an LQFP package. through internal arbiter In addition, by providing sufficient clock outputs for up to four PCI devices, 3.3V PCI I/Os, 5V tolerant board space is further reduced by eliminating the need for an external clock MSI generation and handling using buffer. interrupt and GPIO signals Tundra ConfidentialTsi382 PCI Express to PCI Bridge Low Power Consumption Other Features Masquerade mode The Tsi382A has typical power consumption of less than 0.7W, and it incorporates advanced power management modes to minimize consumption JTAG IEEE 1149.1, 1149.6 during operation. Four GPIO pins and four interrupt pins that can generate MSIs High Performance D0, D3 hot, D3 cold power In addition to low-latency operation, the Tsi382As superior queueing management state support architecture and rich feature set allow designers to optimize their overall 1.2V core power supply, 3.3V I/O system performance. Features such as short-term caching also enable No power sequencing constraints designers to tune the devices performance for different applications. Packaging: Transparent and Non-transparent Bridging BGA: 144-pin, 10 x 10 mm, Transparent mode operation is available for efficient, flow-through 0.8 mm ball pitch, Industrial configurations, while non-transparent bridging enables multi-host systems operating temperature, RoHS/Green and is used in applications such as intelligent adapter cards. compliant LQFP: 176-pin, 20 x 20 mm, Typical Applications Commercial operating temperature, The Tsi382A is suited to applications that need to bridge PCIe to downstream RoHS compliant PCI devices. Its flexibility, high performance, small footprint, and low power consumption, make it ideal for a range of applications, including: Benefits Motherboards Enhances system performance by PC adapter cards (communications, graphics, imaging, and multimedia) delivering high throughput and low latency across the bridge Digital video recorders Simplifies system design by offering ExpressCards for laptop computers numerous programmable features Multifunction printers Minimizes board space due to small Line cards and NICs footprint of BGA package Motherboard Application Design Support Tools Tundra is committed to helping customers PCI Slot minimize their time to market. Thats why PCI Slot we provide one of the highest levels of design support in the industry, including: PCI Application notes 10x10 mm footprint Tsi382A Supports up to four Evaluation boards PCI devices off x1 PCIe IC models PCIe Hardware and software development tools Graphics PCIe Slot Processor Chipset Memory Peripherals CPU 80E2040 TA001 01 Tundra Semiconductor Corporation Document: 80E2040 FB001 01 603 March Road, Ottawa, 2009 Tundra Semiconductor Corporation Ontario, Canada, K2K 2M5 All trademarks are property of their respective Phone: +1 613-592-0714 Toll-free: 800-267-7231 owners.
