The second option uses two power supplies; a 3.3 V supply for the I/O pads (V
a dedicated 3.3 V supply for the CPU (V
powered independently from the I/O pad ring enables shutting down of the I/O pad power
supply “on the fly”, while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC domain. The RTC requires a minimum of
power to operate, which can be supplied by an external battery. The device core power

there is no power drain from the RTC battery when V
Reset has four sources on the LPC178x/7x: the RESET pin, the Watchdog reset,
Power-On Reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a
Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating
voltage attains a usable level, starts the Wake-up timer (see description in
