Pericom replicates Intel PCI bridge chip

Pericom Semiconductor Corp. has released a pin-compatible, drop-in replacement for Intel's 21150 PCI bridge device.

The two-port, 32-bit, 66MHz PI7C8150 PCI-to-PCI bridge chip is the first of three Intel-compatible PCI bridges Pericom plans to introduce.

The part can support up to nine devices on a secondary PCI bus and accommodates 3.3V and 5V signaling, enabling communication with legacy as well as current-generation products. The PCI specification sets a limit of one device per add-in card because the loading restriction allows only one device per connection. A secondary bus increases that number.

The PI7C8150MA is housed in a 208-pin FQFP and is sampling now at $15.50 in lots of 5,000.
