LPC2921/2923/2925
ARM9 microcontroller with CAN, LIN, and USB
9.6 Dynamic characteristics: ADC1/2
[1]
All parameters are guaranteed over the virtual junction temperature range by design. Pre-testing is performed at T

= 85
°
C ambient
temperature on wafer level. Cased products are tested at T
amb

°
C (final testing). Both pre-testing and final testing use correlated
test conditions to cover the specified temperature and power supply voltage range.
[2]
Duty cycle clock should be as close as possible to 50 %.
10. Application information
10.1 Operating frequency selection
The LPC2921/2923/2925 is specified to operate at a maximum frequency of 125 MHz,
maximum temperature of 85
°
C, and maximum core voltage of 1.89 V.
Figure 25
and
Figure 26
show that the user can achieve higher operating frequencies for the
LPC2921/2923/2925 by controlling the temperature and the core voltage accordingly.
