Freescale Semiconductor
Overview
— Two full-duplex fast communications controllers (FCCs) that support the following protocols:
– ATM protocol through two UTOPIA level 2 interfaces
– IEEE Std 802.3/Fast Ethernet (10/100)
– HDLC
– Totally transparent operation
— Three full-duplex serial communications controllers (SCCs) support the following protocols:
– High level/synchronous data link control (HDLC/SDLC)
– LocalTalk (HDLC-based local area network protocol)
– Universal asynchronous receiver transmitter (UART)
– Synchronous UART (1x clock mode)
– Binary synchronous communication (BISYNC)
– Totally transparent operation
– QMC support, providing 64 channels per SCC using only one physical TDM interface
— Universal serial bus (USB) controller that is full/low-speed compliant (multiplexed on an SCC)
– USB host mode
– Supports USB slave mode
— Serial peripheral interface (SPI) support for master or slave
—I2C bus controller
— Two serial management controllers (SMCs) supporting:
– UART
– Transparent
– General-circuit interfaces (GCI)
— Time-slot assigner supports multiplexing of data from any of the SCCs and FCCs onto eight
time-division multiplexed (TDM) interfaces. The time-slot assigner supports the following
TDM formats:
– T1/CEPT lines
–T3/E3
– Pulse code modulation (PCM) highway interface
– ISDN primary rate
– Freescale interchip digital link (IDL)
– General circuit interface (GCI)
— User-defined interfaces
— Eight independent baud rate generators (BRGs)
— Four general-purpose 16-bit timers or two 32-bit timers
— General-purpose parallel ports—16 parallel I/O lines with interrupt capability
256 Kbytes of on-chip memory
— Can act as a 256-Kbyte level-2 cache
— Can act as a 256-Kbyte or two 128-Kbyte memory-mapped SRAM arrays
