the watchdog clock (wdclk) source can be selected from the irc or the dedicated watchdog oscillator (wdo). this gives a wide range of potential timing choices of watchdog operation under different power conditions. 7.14 clocking and power control 7.14.1 crystal oscillators the lpc1102 includes two inde pendent oscillators. these are the inte rnal rc oscillator (irc) and the watchdog oscillator. each oscillat or can be used for mo re than one purpose as required in a particular application. following reset, the lpc1102 will ope rate from the internal rc os cillator until switched by software. this allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. see figure 4 for an overview of the lpc1102 clock generation. lpc1102 all information provided in this document is subject to legal disclaimers. ? nxp b.v. 2011. all rights reserved. product data sheet rev. 4 ? 24 june 2011 12 of 39 nxp semiconductors lpc1102 32-bit arm cortex-m0 microcontroller 7.14.1.1 internal rc oscillator the irc may be used as the clock source for th e wdt, and/or as the clock that drives the pll and subsequently the cpu. the nominal irc frequency is 12 mhz. the irc is trimmed to 1 % accuracy over the entire voltage and temperature range. upon power-up or any chip reset, the lpc1102 uses the irc as the clock source. software may later switch to one of the other available clock sources. 7.14.1.2 watchdog oscillator the watchdog oscillator can be us ed as a clock source that directly drives the cpu or the watchdog timer. the watchdog oscillator nomi nal frequency is prog rammable between 7.8 khz and 1.7 mhz. the frequency spread over processing and temperature is ? 40 %. 7.14.2 system pll the pll accepts an input clock frequency in the range of 10 mhz to 25 mhz. the input frequency is multiplied up to a high frequency with a curren t controlled oscillator (cco). the multiplier can be an integer value from 1 to 32. the cco operates in the range of 156 mhz to 320 mhz, so there is an additional divider in the loop to keep the cco within its frequency range while the pll is prov iding the desired output frequency. the pll output frequency must be lower than 100 mhz. the output divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. si nce the minimum output divider value is 2, it is insured that the pll output has a 50 % duty cycle. the pll is turned off and bypassed fig 4. lpc1102 clock generation block diagram system pll irc oscillator external clock watchdog oscillator irc oscillator watchdog oscillator mainclksel (main clock select) syspllclksel (system pll clock select) system clock divider ahb clock 0 (system) ahbclkctrl[1:18] (ahb clock enable) ahb clocks 1 to 18 (memories and peripherals) spi0 peripheral clock divider spi0 uart peripheral clock divider uart wdt clock divider wdt wdtuen (wdt clock update enable) 002aaf527 main clock system clock irc oscillator 18 lpc1102 all information provided in this document is subject to legal disclaimers. ?

s. 7.14.3 wake-up process the lpc1102 begins o peration at power-up by using the 12 mhz irc oscillator as the clock source. this allows chip operation to resume quickly. if an external clock or the pll is needed by the applicat ion, software will need to enable these features and wait for them to stabilize before they ar e used as a clock source. 7.14.4 power control the lpc1102 supports a variety of power control features. there are two special modes of processor power reduction: sleep mode and deep-sleep mode. the cpu clock rate may also be controlled as needed by changing clock sources, reconfiguring pll values, and/or altering the cpu clock divider value. this allows a trade-off of power versus processing speed based on application requirem ents. in addition, a register is provided for shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. selected peripherals have their own clock divider which provides even better power control. 7.14.4.1 power profiles the power consumption in active and sleep modes can be optimized for the application through a simple call to the power profiles. t he power configuration ro utine configures the lpc1102 for one of the following power modes: ?

low-current mode corresponding to lowest power consumption. in addition, the power profiles includes a rout ine to select the optimal pll settings for a given system clock and pll input clock. 7.14.4.2 sleep mode when sleep mode is entered, the clock to the core is stopped. resumption from the sleep mode does not need any special sequence but re-enabling the clock to the arm core. in sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. peripheral functions continue opera tion during sleep mode and may generate interrupts to cause the processor to resume execution. sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 7.14.4.3 deep-sleep mode in deep-sleep mode, the chip is in sleep mode, and in addition all analog blocks are shut down except for the watchdog oscillator and the bod circuit, which can be configured to remain running in deep-sleep mode to allow a reset initiated by a timer or bod event. deep-sleep mode allows for additional power savings. lpc1102 all information provided in this document is subject to legal disclaimers. ?

to improve the adc performance in a very no isy environment, put the device in sleep mode during the adc conversion. 11.2 xtal input the input voltage to the on-chip oscillators is limited to 1.8 v. if the oscillator is driven by a clock in slave mode, it is recommended that th e input be coupled through a capacitor with c i = 100 pf. to limit the input voltage to the specified range, choose an additional capacitor to ground c g which attenuates the input voltage by a factor c i /(c i + c g ). in slave mode, a minimum of 200 mv (rms) is needed. in slave mode the input clock signal should be coupled by means of a capacitor of 100 pf ( figure 19 ), with an amplitude between 200 mv (rms) and 1000 mv (rms). this corresponds to a square wave signal with a signal swing of between 280 mv and 1.4 v. 11.3 standard i/o pad configuration figure 20 shows the possible pin modes for standard i/o pins with analog input function: ?
