Freescale Semiconductor
Features
— Dedicated interface logic for SDRAM
CPU core can be disabled and the device can be used in slave mode to an external core
Communications processor module (CPM)
— Embedded 32-bit communications processor (CP) uses a RISC architecture for flexible support
for communications protocols
— Interfaces to G2 core through on-chip 32-Kbyte dual-port RAM and DMA controller
— Serial DMA channels for receive and transmit on all serial channels
— Parallel I/O registers with open-drain and interrupt capability
— Virtual DMA functionality executing memory-to-memory and memory-to-I/O transfers
— Three fast communications controllers supporting the following protocols:
– 10/100-Mbit Ethernet/IEEE 802.3 CDMA/CS interface through media independent
interface (MII)
– Transparent
– HDLC—Up to T3 rates (clear channel)
— One multichannel controller (MCC2)
– Handles 128 serial, full-duplex, 64-Kbps data channels. The MCC can be split into four
subgroups of 32 channels each.
– Almost any combination of subgroups can be multiplexed to single or multiple TDM
interfaces up to four TDM interfaces per MCC
— Four serial communications controllers (SCCs) identical to those on the MPC860, supporting
the digital portions of the following protocols:
– Ethernet/IEEE 802.3 CDMA/CS
– HDLC/SDLC and HDLC bus
– Universal asynchronous receiver transmitter (UART)
– Synchronous UART
– Binary synchronous (BISYNC) communications
– Transparent
— Two serial management controllers (SMCs), identical to those of the MPC860
– Provide management for BRI devices as general circuit interface (GCI) controllers in time-
division-multiplexed (TDM) channels
– Transparent
– UART (low-speed operation)
— One serial peripheral interface identical to the MPC860 SPI
— One inter-integrated circuit (I2C) controller (identical to the MPC860 I2C controller)
– Microwire compatible
– Multiple-master, single-master, and slave modes
— Up to four TDM interfaces
– Supports one group of four TDM channels
