BOARD LAYOUT:
POWER SUPPLY CIRCUIT:
RESET CIRCUIT:
CLOCK CIRCUIT:
LPC-E2468 can take power from power connector PWR, where +(9-12) VDC
or (6-9) VAC external voltage source has to be applied. The board could also
take power from USB_D or from battery. Note: the battery only supplies the
internal 2MB SRAM and the RTC.
The board power consumption is: about 150 mA at 9VDC.
LPC-E2468 reset circuit is made with RC group R4 – 47K, C20 – 100nF
and RESET button.
Quartz crystal 12MHz is connected to LPC2468 pin 44 (XTAL1) and pin 46
(XTAL2).
32.768 KHz quartz crystal is connected to LPC2468 pin 34 (RTCX1) and
pin 36 (RTCX2) for its internal Real Time Clock.
