MPC862EC 数据手册

Freescale Semiconductor, Inc.

Features

— 12 port pins with interrupt capability

— The MPC862P and MPC862T have 23 internal interrupt sources; the MPC857T and

MPC857DSL have 20 internal interrupt sources

— Programmable priority between SCCs (MPC862P and MPC862T)

— Programmable highest priority request

Communications processor module (CPM)

— RISC controller

•

— Communication-speciﬁc commands (for example, GRACEFUL STOP TRANSMIT, ENTER HUNT

MODE, and RESTART TRANSMIT)

— Supports continuous mode transmission and reception on all serial channels

— Up to 8-Kbytes of dual-port RAM

— The MPC862P and MPC862T have 16 serial DMA (SDMA) channels; the MPC857T and

MPC857DSL have 10 serial DMA (SDMA) channels

— Three parallel I/O registers with open-drain capability

Four baud rate generators

•

— Independent (can be connected to any SCC or SMC)

— Allow changes during operation

— Autobaud support option

The MPC862P and MPC862T have four SCCs (serial communication controller) The MPC857T

and MPC857DSL have one SCC, SCC1; the MPC857DSL supports ethernet only

— Serial ATM capability on all SCCs

— Optional UTOPIA port on SCC4

— Ethernet/IEEE 802.3 optional on SCC1–4, supporting full 10-Mbps operation

— HDLC/SDLC

— HDLC bus (implements an HDLC-based local area network (LAN))

— Asynchronous HDLC to support PPP (point-to-point protocol)

— AppleTalk

— Universal asynchronous receiver transmitter (UART)

— Synchronous UART

— Serial infrared (IrDA)

— Binary synchronous communication (BISYNC)

— Totally transparent (bit streams)

— Totally transparent (frame based with optional cyclic redundancy check (CRC))

Two SMCs (serial management channels) (The MPC857DSL has one SMC, SMC1 for UART)

— UART

•

— Transparent

— General circuit interface (GCI) controller

— Can be connected to the time-division multiplexed (TDM) channels

One serial peripheral interface (SPI)

— Supports master and slave modes

— Supports multiple-master operation on the same bus
