Description
The PM7384-BI-P is an integrated circuits (IC) chip that comes under the product category of IC Chips. This monolithic IC is designed to implement HDLC processing and PCI bus memory management functions. It is capable of handling a maximum of 672 bi-directional channels.
Specifications and features
- Single-chip multi-channel HDLC controller with a 66 MHz, 32 bit Peripheral Component Interconnect (PCI) Revision 2.1 bus for configuration, monitoring and transfer of packet data.
- On-chip DMA controller with scatter/gather capabilities.
- Supports up to 672 bi-directional HDLC channels assigned to a maximum of 84 channelised or unchannelised links conveyed via a Scaleable Bandwidth Interconnect (SBI) interface.
- Data on the SBI interface is divided into 3 Synchronous Payload Envelopes (SPEs).
- Three bi-directional HDLC channels each assigned to an unchannelised link with an arbitrary rate link of up to 51.84 MHz when SYSCLK is running at 45 MHz.
- 32 Kbytes of on-chip memory for partial packet buffering in both the transmit and receive directions.
- Low power 2.5 Volt 0.25 μm CMOS technology.
- 352 pin enhanced ball grid array (SBGA) package.
