Product Features


 Single-chip Peripheral Component Interconnect (PCI) Bus multi-channel HDLC controller.  

 Supports up to 128 bi-directional HDLC channels assigned to a maximum of 8 channelised T1  or E1 links. The number of time-slots assigned to an HDLC channel is programmable from 1  to 24 (for T1) and from 1 to 31 (for E1).  

 Supports up to 8 bi-directional HDLC channels each assigned to an unchannelised arbitrary  rate link; subject to a maximum aggregate link clock rate of 64 MHz in each direction.  Channels assigned to links 0 to 2 can have a clock rate of up 52 MHz when SYSCLK is at 33  MHz. Channels assigned to links 3 to 7 can have a clock rate of up to 10 MHz.  

 Supports up to two bi-directional HDLC Channels each assigned to an unchannelised arbitrary  rate link of up to 52 MHz when SYSCLK is at 33 MHz.  

 Supports a mix of up to 8 channelised and unchannelised links; subject to the constraint of a  maximum of 128 channels and a maximum aggregate link clock rate of 64 MHz in each  direction.  

 For each channel, the HDLC receiver performs flag sequence detection, bit de-stuffing, and  frame check sequence validation. The receiver supports the validation of both CRC-CCITT  and CRC-32 frame check sequences. The receiver also checks for packet abort sequences,  octet aligned packet length and for minimum and maximum packet length.  

 Alternatively, for each channel, the receiver supports a transparent mode where each octet is  transferred transparently to host memory. For channelised links, the octets are aligned with  the receive time-slots.  

 For each channel, time-slots are selectable to be in 56 kbits/s format or 64 kbits/s clear  channel format.  

 For each channel, the HDLC transmitter performs flag sequence generation, bit stuffing, and,  optionally, frame check sequence generation. The transmitter supports the generation of  both CRC-CCITT and CRC-32 frame check sequences. The transmitter also aborts packets  under the direction of the host or automatically when the channel underflows.  

 Supports two levels of non-preemptive packet priority on each transmit channel. Low priority  packets will not begin transmission until all high priority packets are transmitted.  

 Alternatively, for each channel, the transmitter supports a transparent mode where each octet  is inserted transparently from host memory. For channelised links, the octets are aligned with  the transmit time-slots.  

 Directly supports a 32-bit, 33 MHz PCI 2.1 interface for configuration, monitoring and transfer  of packet data, with an on-chip DMA controller with scatter/gather capabilities.

 Provides 8 kbytes of on-chip memory for partial packet buffering in each direction. This  memory can be configured to support a variety of different channel configurations from a  single channel with 8 kbytes of buffering to 128 channels, each with a minimum of 48 bytes of  buffering.  

 Supports PCI burst sizes of up to 128 bytes for transfers of packet data.  

 Pin compatible with PM7364 (FREEDM-32) device.  

 Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board test purposes.  

 Supports 3.3 and 5 Volt PCI signaling environments.  

 Low power CMOS technology.  

 256 pin enhanced ball grid array (SBGA) or 272 pin plastic ball grid array (PBGA) packages  (27 mm X 27 mm).
