LPC2926/2927/2929
ARM9 microcontroller with CAN, LIN, and USB
9.7 Dynamic characteristics: ADC
[1]
All parameters are guaranteed over the virtual junction temperature range by design. Pre-testing is performed at T
amb
= 85
°
C ambient
temperature on wafer level. Cased products are tested at T
amb
= 25
°
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 LPC2926/2927/2929 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 30
and
Figure 31
show that the user can achieve higher operating frequencies for the
LPC2926/2927/2929 by controlling the temperature and the core voltage accordingly.
