80960SB Datasheet, PDF (37/38 Pages) Intel Corporation – EMBEDDED 32-BIT MICROPROCESSOR WITH 16-BIT BURST DATA BUS

80960SB
5.0 REVISION HISTORY
This data sheet supersedes data sheet 272207-001. The sections significantly changed since the previous
revision are:
Section
2.3 Connection Recommendations (pg. 11)
2.5 Test Load Circuit (pg. 13)
2.7 DC Characteristics (pg. 14)

Description
Removed two LOCK pin Connection Recommendation
figures and added Figure 5 to reflect the new LOCK
pin connection recommendation of a single 910Ω
pullup resistor.
Obsolete figure (Test Load Circuit for Open-Drain
Output Pins) removed to reflect current test conditions.
I_OL value improved.
WAS:
2.5 mA
IS:
4.0 mA
LOCK pin I_OL value at 0.45V relaxed.
WAS: 12 mA
IS:
6 mA
LOCK pin I_OL value at 0.60V deleted.
Data sheet 270917-004 applied to both the 80960SA and the 80960SB. The 80960SB was then documented
alone in data sheet 272207-001. The sections significantly changed between revisions -004 of the SA/SB data
sheet and 272207-001 of the SB data sheet were:
