16 Important notes
Important notes
With the objective of continuous improvement, ST has developed ST72F324B-Auto devices.
These devices are fully compatible with all ROM features and provide an improved
price/performance ratio compared to the ST72F324-Auto Flash devices.
A summary of the technical improvements is given below. Refer to the separate ST72324B-
Auto datasheet for the ordering information and full specifications.
16.1 Reset pin logic levels
In ST72F324B-Auto Flash devices, the VIH/VIL levels for the reset pin are the same as
) specified for ROM devices.
te Product(s 16.2
Wake-Up from Active Halt mode using external interrupts
In ST72F324B Flash devices, any external interrupt that capable of waking-up the MCU
from Halt mode can also wake-up the MCU from Active Halt mode. Consequently Note 1
below Table 25: Interrupt mapping on page 52 does not apply to ‘B’ devices.
- Obsole 16.3
PLL jitter
In ST72F324B-Auto Flash devices, PLL clock accuracy is improved and the jitter is the
same as specified for ROM devices.
roduct(s) 16.4
Active Halt power consumption
In ST72F324B-Auto Flash devices, the power consumption in Active Halt mode is specified
as 230µA max. See Table 84: Current characteristics on page 148 for test conditions.
Obsolete P 16.5
Timer A registers
In ST72F324B-Auto Flash devices, all Timer A registers are present and their functionality is
the same as described for ROM devices in the ST72324B-Auto datasheet.
