Caution Set the detection voltage (V
LVD) to be within the operating voltage range. The operating voltage range
depends on the setting of the user option byte (000C2H/010C2H). The following shows the operating
voltage range.
HS (high-speed main) mode: V
DD = 2.7 to 3.6 V@1 MHz to 32 MHz
VDD = 2.4 to 3.6 V@1 MHz to 16 MHz
LS (low-speed main) mode: V
DD = 1.8 to 3.6 V@1 MHz to 8 MHz
LV (low-voltage main) mode: V
DD = 1.6 to 3.6 V@1 MHz to 4 MHz

(T
A = −40 to +85°C, VSS = 0 V)
Parameter Symbol Conditions MIN. TYP. MAX. Unit
Supply voltage rise SVDD 54 V/ms
Caution Be sure to maintain the internal reset state until VDD reaches the operating voltage range specified in
29.4 AC Characteristics, by using the LVD circuit or external reset pin.
