DESCRIPTION
Initial release
TSOC package added; corrected Electrical Characteristics table Note
20
Updated the text and graphics to mark which features are not
applicable in the low-voltage environment
Created a second Electrical Characteristics table for 3.3V V PUP (±5%),
operating temp range 0°C to +70°C, no overdrive
Removed information about the registration number being factory
lasered into the chip in the General Description section, 64-Bit ROM
section, Figure 3, and CRC Generation section
Changed 125kbps to 90kbps in the Features and Hardware
Configuration sections
Updated the soldering information and added lead temperature
information in the Absolute Maximum Ratings section
Updated the 5.0V/3.0V Supply Electrical Characteristics tables
parameters for C IO , I L , t REC , t SLOT , I PROG , and related notes
Replaced the last sentence of the Read Memory [F0h] and Extended
Read Memory [A5h] sections to clarify the command
Added the Package Information table
Revised the 5.0V Supply Electrical Characteristics table Notes 1, 4,
and 15
Revised the 3.3V Supply Electrical Characteristics table Notes 3 and
14
In the 5.0V Supply Electrical Characteristics table, changed the t RL(MIN)
overdrive speed from 1μs to 0.800μs; changed the t MSR(MAX) overdrive
speed from 2μs to 2.27μs
