MPC860 Family Hardware Specifications

Motorola => Freescale 

Maximum Tolerated Ratings

— Allows independent transmit and receive routing, frame synchronization,

clocking

— Allows dynamic changes

— Can be internally connected to six serial channels (four SCCs and two SMCs)

• Parallel interface port (PIP)

— Centronics interface support

— Supports fast connection between compatible ports on the MPC860 or the

MC68360

• PCMCIA interface

— Master (socket) interface, release 2.1 compliant

— Supports two independent PCMCIA sockets

— Eight 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 and PIT, PLL active for fast wake up

— Deep sleep—all units disabled including PLL, except RTC and PIT

— 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 ball grid array (BGA) package

Part III Maximum Tolerated Ratings

This section provides the maximum tolerated voltage and temperature ranges for the

MPC860. Table 3-2 provides the maximum ratings.

This device contains circuitry protecting against damage due to high-static voltage or

electrical fields; however, it is advised that normal precautions be taken to avoid application

of any voltages higher than maximum-rated voltages to this high-impedance circuit.

Reliability of operation is enhanced, if unused inputs are tied to an appropriate logic voltage

level (for example, either GND or Vdd).
