79RC64574 79RC64575
September 9, 1999: Made several changes in JTAG Interface
section of Table 5. Added information on Pin 63 in Table 5.
October 14, 1999: Revised data in the Power Consumption tables
for RC64574 and RC64575.
November 16, 1999: Added Power Curve graphs, revised data in
System Interface Parameters table, added System Clock Jitter row to
Clock Parameter table.
12, Changed pin #75 function from Vcc to N.C.
March 7, 2000: In Table 1, added “with DSP extensions” in the CPU
row under RC64574 and RC64575 columns and changed “by set” to “by
line” in the Caches row for RC64574 and RC64575 columns. Added
rows in the Data Output and Data Output Hold rows in the System Inter-
face Parameters table. Removed references to 300 MHz, and changed
bandwidth speed to 2GB/second in Cache Memory section. Revised
Power Curves.
March 28, 2000: Replaced existing figure in Mode Configuration
Interface Reset Sequence section with 3 reset figures. Revised values
for 250MHz in System Interface Parameters table. Changed Data Sheet
from Preliminary to final.
April 3, 2000: Deleted signal tDZ from Figure 6.
April 25, 2001: In the Absolute Maximum Ratings table, changed
upper voltage limit from 3.8 to 4.0V and removed “Vin should not exceed
Vcc +0.5 volts” from footnote #1. In DC Electrical Characteristics table,
changed maximum value for Vih from 3.3 to 3.8V for all speeds.
May 1, 2001: In the Data Output Hold category of the System Inter-
face Parameters table, changed values in the Min column for all speeds
from 1.0 to 0. In the Electrical Characteristics table, values were added
to the System Clock Jitter row. Added Industrial temperature range of
-40
° C to +85° C.
December 14, 2001: In Absolute Maximum Ratings Table, changed
the Industrial low-end temperature for symbol Tc to read -40 degrees
instead of 0 degrees.
