The MPC862/857T/857DSL provides enhanced ATM functionality over that of the MPC860SAR.
The MPC862/857T/857DSL adds major new features available in “enhanced SAR” (ESAR) mode,
including the following:
— Improved operation, administration and maintenance (OAM) support
— OAM performance monitoring (PM) support
— Multiple APC priority levels available to support a range of traffic pace requirements
— ATM port-to-port switching capability without the need for RAM-based microcode
— Simultaneous MII (10/100Base-T) and UTOPIA (half-duplex) capability
— Optional statistical cell counters per PHY
— UTOPIA level 2 compliant interface with added FIFO buffering to reduce the total cell
— Multi-PHY support on the MPC857T
— Four PHY support on the MPC857DSL
— Parameter RAM for both SPI and I
— Supports full-duplex UTOPIA both master (ATM side) and slave (PHY side) operation using
— AAL2/VBR functionality is ROM-resident
Up to 32-bit data bus (dynamic bus sizing for 8, 16, and 32 bits)
32 address lines
Memory controller (eight banks)
— Contains complete dynamic RAM (DRAM) controller
— Each bank can be a chip select or RAS to support a DRAM bank
— Up to 30 wait states programmable per memory bank
— Glueless interface to Page mode/EDO/SDRAM, SRAM, EPROMs, flash EPROMs, and other
— DRAM controller programmable to support most size and speed memory interfaces
— Four CAS lines, four WE lines, one OE line
— Boot chip-select available at reset (options for 8-, 16-, or 32-bit memory)
— Variable block sizes (32 Kbyte–256 Mbyte)
— Selectable write protection
— On-chip bus arbitration logic
General-purpose timers
— Four 16-bit timers cascadable to be two 32-bit timers
— Gate mode can enable/disable counting
— Interrupt can be masked on reference match and event capture
Fast Ethernet controller (FEC)
— Simultaneous MII (10/100Base-T) and UTOPIA operation when using the UTOPIA
transmission time. (The earlier UTOPIA level 1 specification is also supported.)
