Preliminary data sheet
NXP Semiconductors
Reset, Clock, and Power
Controller (RCPC)
The RCPC generates the various clock signals for the
operation of the LH79520 and provides for an orderly
start-up after power-on and during a wake-up from one
of the power saving operating modes. The RCPC allows
the software to individually select the frequency of the
various on-chip clock signals as required to operate the
chip in the most power-efficient mode. It features:
14.7456 MHz crystal oscillator and PLL for on-chip
Clock generation
External Clock input if on-chip oscillator and PLL are
not used
32.768 kHz crystal oscillator generating 1 Hz clock
for Real Time Clock
Individually controlled clocks for peripherals and CPU
Clock source for UARTs is selectable between
14.7456 MHz crystal oscillator and external clock
source
Programmable clock prescalers for UARTs and
PWMs
Five global power control modes are available:
– Active
– Standby
– Sleep
– Stop1
– Stop2
CPU and Bus clock frequency can be changed
on the fly
Selectable clock output
Hardware reset (nRESETIN) and software reset.
The 32.768 kHz crystal oscillator is not required for
chip operation, so it may be left out of the design to
save power. If this crystal is not used, XTALIN should
be pulled to VDD or VSS so the input does not float.
