MPC860 Family Hardware Speciﬁcations

MOTOROLA

Features

— Decrementer, time base, and real-time clock (RTC) from the PowerPC

architecture

— Reset controller

— IEEE 1149.1 test access port (JTAG)

•

Interrupts

— Seven external interrupt request (IRQ) lines

— 12 port pins with interrupt capability

— 23 internal interrupt sources

— Programmable priority between SCCs

— Programmable highest priority request

•

10/100 Mbps Ethernet support, fully compliant with the IEEE 802.3u Standard (not

available when using ATM over UTOPIA interface)

•

ATM support compliant with ATM forum UNI 4.0 speciﬁcation

— Cell processing up to 50–70 Mbps at 50-MHz system clock

— Cell multiplexing/demultiplexing

— Support of AAL5 and AAL0 protocols on a per-VC basis. AAL0 support enables

OAM and software implementation of other protocols).

— ATM pace control (APC) scheduler, providing direct support for constant bit rate

(CBR) and unspeciﬁed bit rate (UBR) and providing control mechanisms

enabling software support of available bit rate (ABR)

— Physical interface support for UTOPIA (10/100-Mbps is not supported with this

interface) and byte-aligned serial (for example, T1/E1/ADSL)

— UTOPIA-mode ATM supports level-1 master with cell-level handshake,

multi-PHY (up to 4 physical layer devices), connection to 25-, 51-, or 155-Mbps

framers, and UTOPIA/system clock ratios of 1/2 or 1/3.

— Serial-mode ATM connection supports transmission convergence (TC) function

for T1/E1/ADSL lines; cell delineation; cell payload scrambling/descrambling;

automatic idle/unassigned cell insertion/stripping; header error control (HEC)

generation, checking, and statistics.

•

Communications processor module (CPM)

— RISC communications processor (CP)

— 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 8Kbytes of dual-port RAM

— 16 serial DMA (SDMA) channels
