Specification Clarifications

The Specification clarifications listed in this section (If any) apply to the following

documents:

• Intel

Celeron

D Processors 340, 335, 330, 325, and 320 Datasheet - On 90 nm

Process in the 478-pin Package Datasheet

• Intel

Celeron

D Processor 3xx Sequence – On 90 nm Process in the 775-Land

Package Datasheet

All Specification Clarifications will be incorporated into a future version of the

appropriate Celeron D processor on 90 nm process and in the 478-pin package/775

Land Package processor documentation.

L1. THERMTRIP# De-assertion Clarification for the 478-pin Package

The following text is an updated description of THERMTRIP# signal as defined in Table

4-3 (Signal description table) of the Intel

Celeron

D Processor 3xx Sequence

Datasheet.

Driving of the THERMTRIP# signal is enabled within 10 us of the assertion of

PWRGOOD (provided VIDPWRGD, VCCVID, and Vcc are asserted) and is disabled on

de-assertion of PWRGOOD (if VIDPWRGD, VCCVID, or Vcc are not valid, THERMTRIP#

may also be disabled). Once activated, THERMTRIP# remains latched until

PWRGOOD, VIDPWRGD, VCCVID or Vcc is de-asserted. While the de-assertion of the

PWRGOOD, VIDPWRGD, VCCVID or Vcc signal will de-assert THERMTRIP#, if the

processor’s junction temperature remains at or above the trip level, THERMTRIP# will

again be asserted within 10 us of the assertion of PWRGOOD (provided VIDPWRGD,

VCCVID, and Vcc are asserted).

L2. THERMTRIP# De-assertion Clarification for the 775-Land Package

The following text is an updated description of THERMTRIP# signal as defined in Table

4-3 (Signal description table) of the Intel

Celeron

D Processor 3xx Sequence

Datasheet.

Driving of the THERMTRIP# signal is enabled within 10 us of the assertion of

PWRGOOD (provided VTTPWRGD, VTT, and Vcc are asserted) and is disabled on de-

assertion of PWRGOOD (if VTTPWRGD, VTT, or Vcc are not valid, THERMTRIP# may

also be disabled). Once activated, THERMTRIP# remains latched until PWRGOOD,

VTTPWRGD, VTT or Vcc is de-asserted. While the de-assertion of the PWRGOOD,
