ST10F272B/ST10F272E
Introduction
Clock module, the Power-down consumption is dominated by the consumption of the
oscillator amplifier itself.
A second on-chip oscillator amplifier circuit (32kHz) is implemented for low power modes: it
can be used to provide the reference to the Real Time Clock counter (either in Power Down
or Stand-by mode). Pin XTAL3 and XTAL4 replace a couple of VDD/VSS pins of ST10F269.
Possibility to re-program internal XBUS chip select window characteristics (XRAM2 window)
is added.
