Description of Changes
Title Page:
Changed the Revision number from 3.0 to 4.0. Changed the date format to DD MMM YYYY. Made the same
changes in the lower left corner of the back page.
Added the sentence directly preceding Table 1: ‘Unless noted in this data sheet, all specifications apply
from TL to TH.’
Sections 3.7.1, 3.7.2 and 3.7.3: Reordered sections resulting in the following order and section renumbering:
Added the following text directly before this section and after Table 8 Pin Status for Medium and Slow Pads During
the Power-on Sequence:
‘The values in Table 7 and Table 8 do not include the effect of the weak pull devices on the output pins during
power up.
Before exiting the internal POR state, the voltage on the pins goes to high-impedance until POR negates. When
the internal POR negates, the functional state of the signal during reset applies and the weak pull devices (up
or down) are enabled as defined in the device Reference Manual. If VDD is too low to correctly propagate the
logic signals, the weak-pull devices can pull the signals to VDDE and VDDEH.
To avoid this condition, minimize the ramp time of the VDD supply to a time period less than the time required to
enable the external circuitry connected to the device outputs.’
Section 3.7.3, “Power-Down Sequence (VRC33 Grounded)” Deleted the underscore in ORed_POR to become ORed POR.
