4. Module: DC Characteristics
The specifications and parameter numbers for the
Brown-out Reset Voltage limits (V
BOR, originally
parameter D005) in Section 25.1 “DC Character-
istics: Supply Voltage” of the Device Data Sheet
have been changed.
The specifications and parameter numbers have
been revised for devices with date codes from
0401xxx to 0420xxx, inclusive.
Specifications and parameter numbers have been
revised for specific temperature ranges for date
codes from 0421xxx and higher.
The new information is shown in bold text.

Legend: Shading of rows is to assist in readability of the table.
Note 1: This is the limit to which V
DD can be lowered in Sleep mode, or during a device Reset, without losing RAM data.
2: When BOR is on and BORV<1:0> = 0x, the device will operate correctly at 40 MHz for any V
DD at which the BOR
allows execution.
