Freescale Semiconductor
— Eight independent baud rate generators and 20 input clock pins for supplying clocks to FCCs,
— Four independent 16-bit timers that can be interconnected as two 32-bit timers
PCI bridge
— PCI Specification Revision 2.2 compliant and supports frequencies up to 66 MHz
— On-chip arbitration
— Support for PCI to 60x memory and 60x memory to PCI streaming
— PCI Host Bridge or Periphera
— Includes 4 DMA channels for the following transfers:
— Includes all of the configuration registers (which are automatically loaded from the EPROM
— Supports the I
— Hot-Swap friendly (supports the Hot Swap Specification as defined by PICMG 2.1 R1.0
— Support for 66 MHz, 3.3 V specification
— 60x-PCI bus core logic which uses a buffer pool to allocate buffers for each port
— Makes use of the local bus signals, so there is no need for additional pins
– 2,048 bytes of SI RAM
– Bit or byte resolution
– Independent transmit and receive routing, frame synchronization
– Supports T1, CEPT, T1/E1, T3/E3, pulse code modulation highway, ISDN basic rate, ISDN
SCCs, SMCs, and serial channels
