LPC2364/2366/2368
Fast communication chip
7.24.1.1
Internal RC oscillator
The Internal RC oscillator (IRC) may be used as the clock source for the watchdog timer,
and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC
frequency is 4 MHz. The IRC is trimmed to 1 % accuracy.
Upon power-up or any chip reset, the LPC2364/66/68 uses the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.24.1.2
Main oscillator
The main oscillator can be used as the clock source for the CPU, with or without using the
PLL. The main oscillator operates at frequencies of 1 MHz to 24 MHz. This frequency can
be boosted to a higher frequency, up to the maximum CPU operating frequency, by the
PLL. The oscillator output is called OSCCLK. The clock selected as the PLL input is
PLLCLKIN, and the ARM processor clock frequency is referred to as CCLK elsewhere in
this document. The frequencies of PLLCLKIN and CCLK are the same value unless the
PLL is active and connected. Refer to
Section 7.24.2
for additional information.
7.24.1.3
RTC oscillator
The RTC oscillator can be used as the clock source for the RTC and/or the watchdog
timer. Also, the RTC oscillator can be used to drive the PLL and the CPU.
7.24.2
PLL
The PLL accepts an input clock frequency in the range of 31 kHz to 50 MHz. The input
frequency is multiplied up to a high frequency, then divided down to provide the actual
clock used by the CPU and the USB block.
The PLL input, in the range of 32 kHZ to 50 MHz, may initially be divided down by a value
‘N’, which may be in the range of 1 to 256. This input division provides a wide range of
output frequencies from the same input frequency.
Following the PLL input divider is the PLL multiplier. This can multiply the input divider
output through the use of a Current Controlled Oscillator (CCO) by a value ‘M’, in the
range of 1 through 32768. The resulting frequency must be in the range of 275 MHz to
550 MHz. The multiplier works by dividing the CCO output by the value of M, then using a
phase-frequency detector to compare the divided CCO output to the multiplier input. The
error value is used to adjust the CCO frequency.
The PLL is turned off and bypassed following a chip Reset and by entering Power-down
mode. PLL is enabled by software only. The program must configure and activate the PLL,
wait for the PLL to Lock, then connect to the PLL as a clock source.
7.24.3
Wake-up timer
The LPC2364/66/68 begins operation at power-up and when awakened from Power-down
mode or Deep power-down mode by using the 4 MHz IRC oscillator as the clock source.
This allows chip operation to resume quickly. If the main oscillator or the PLL is needed by
the application, software will need to enable these features and wait for them to stabilize
before they are used as a clock source.
When the main oscillator is initially activated, the wake-up timer allows software to ensure
that the main oscillator is fully functional before the processor uses it as a clock source
and starts to execute instructions. This is important at power on, all types of Reset, and
