16 IMPORTANT NOTES ON ST72F324B FLASH DEVICES:
With the objective of continuous improvement, ST
has developed new ST72F324B devices. These
devices are fully compatible with all ROM features
and provide an improved price/performance ratio
compared to the ST72F324 flash devices.
A summary of the technical improvements is given
below.
Refer to separate ST72324B datasheet for the or-
dering information and full specifications.
16.1 Reset Pin Logic levels
In ST72F324B Flash devices, the V
the reset pin are the same as specified for ROM
devices
16.2 Wake-Up from Active Halt mode using
external interrupts
In ST72F324B Flash devices, any external inter-
rupt that capable of waking-up the MCU from Halt
mode can also wake-up the MCU from Active Halt
mode. Consequently note 1 below
page 36
16.3 PLL Jitter
In ST72F324B Flash devices, PLL clock accuracy
is improved and the jitter is the same as specified
for ROM devices
16.4 Active Halt Power Consumption
In ST72F324B Flash devices, the power con-
sumption in Active Halt mode is specified as
230µA max. See
conditions.

16.5 Timer A Registers
In ST72F324B Flash devices, all Timer A registers
are present and their functionality is the same as
described for ROM devices in the ST72324B da-
tasheet.
