MPC862/857T/857DSL Hardware Speciﬁcations

Features

•

One inter-integrated circuit (I2C) port

— Supports master and slave modes

— Multiple-master environment support

•

Time-slot assigner (TSA) (The MPC857DSL does not have the TSA)

— Allows SCCs and SMCs to run in multiplexed and/or non-multiplexed operation

— Supports T1, CEPT, PCM highway, ISDN basic rate, ISDN primary rate, user deﬁned

— 1- or 8-bit resolution

— Allows independent transmit and receive routing, frame synchronization, clocking

— Allows dynamic changes

— On the MPC862P and MPC862T, can be internally connected to six serial channels (four SCCs

and two SMCs); on the MPC857T, can be connected to three serial channels (one SCC and two

SMCs)

•

Parallel interface port (PIP)

— Centronics interface support

— Supports fast connection between compatible ports on MPC862/857T/857DSL or MC68360

•

PCMCIA interface

— Master (socket) interface, release 2.1 compliant

— Supports one or two PCMCIA sockets dependent upon whether ESAR functionality is enabled

— 8 memory or I/O windows supported

•

Low power support

— Full on—All units fully powered

— Doze—Core functional units disabled except time base decrementer, PLL, memory controller,

RTC, and CPM in low-power standby

— Sleep—All units disabled except RTC, PIT, time base, and decrementer with PLL active for fast

wake up

— Deep sleep—All units disabled including PLL except RTC, PIT, time base, and decrementer.

— Power down mode— All units powered down except PLL, RTC, PIT, time base and

decrementer

•

Debug interface

— Eight comparators: four operate on instruction address, two operate on data address, and two

operate on data

— Supports conditions: =

≠ < >

— Each watchpoint can generate a break point internally

•

3.3 V operation with 5-V TTL compatibility except EXTAL and EXTCLK

•

357-pin plastic ball grid array (PBGA) package

•

Operation up to 100MHz

The MPC862/857T/857DSL is comprised of three modules that each use the 32-bit internal bus: the

MPC8xx core, the system integration unit (SIU), and the communication processor module (CPM). The

MPC862P/862T block diagram is shown in Figure 1. The MPC857T/857DSL block diagram is shown in

Figure 2.
