PACKAGE INFORMATION

The 80960JD is offered with three speeds and two

package types. The 132-pin Pin Grid Array (PGA)

device is specified for operation at VCC =3.3 V ± 5%

over a case temperature range of 0° to 100°C:

• A80960JD-66 (66 MHz core, 33 MHz bus)

• A80960JD-50 (50 MHz core, 25 MHz bus)

• A80960JD-40 (40 MHz core, 20 MHz bus)

The 132-pin Plastic Quad Flatpack (PQFP) devices

will be specified for operation at VCC = 3.3 V ± 5%

over a case temperature range of 0° to 100°C:

• NG80960JD-66 (66 MHz core, 33 MHz bus)

• NG80960JD-50 (50 MHz core, 25 MHz bus)

• NG80960JD-40 (40 MHz core, 20 MHz bus)

Functional Pin Definitions

Table 2 presents the legend for interpreting the pin

descriptions which follow. Pins associated with the

bus interface are described in Table 3. Pins

associated with basic control and test functions are

described in Table 4. Pins associated with the

Interrupt Unit are described in Table 5.

Description

Input pin only.

Output pin only.

I/O

Pin can be either an input or output.

–

Pin must be connected as described.

Synchronous. Inputs must meet setup

and hold times relative to CLKIN for

proper operation.

S(E) Edge sensitive input

S(L) Level sensitive input

A (...)

Asynchronous. Inputs may be

asynchronous relative to CLKIN.

A(E) Edge sensitive input

A(L) Level sensitive input

R (...)

While the processor’s RESET pin is

asserted, the pin:

R(1) is driven to VCC

R(0) is driven to VSS

R(Q) is a valid output

R(X) is driven to unknown state

R(H) is pulled up to VCC

H (...)

While the processor is in the hold state,

the pin:

H(1) is driven to VCC

H(0) is driven to VSS

H(Q) Maintains previous state or

continues to be a valid output

H(Z) Floats

P (...)

While the processor is halted, the pin:

P(1) is driven to VCC

P(0) is driven to VSS

P(Q) Maintains previous state or

continues to be a valid output
