1.2 I/O AND AS/DS/RW DRIVE
The high drive option (EMR1.BSZ bit=1) available in the ST92F150 does not exist in the
ST92F250. This means that whatever the value of the BSZ bit (bit 1 of the EMR1 register,
R245 page 21), the I

This could impact an application ported from ST92F150 to ST92F250 in terms of external
memory access speed (if EMR1.BSZ bit=1 in the application):
– If the application code doesn't modify the reset state of the BSZ bit, the External Memory
– If the application code modifies the reset state of the BSZ bit, the External Memory Interface
1.3 WKUP6 MAPPING
The ST92F120/F124/F150/F250 microcontrollers have a STOP low power mode which can
be exited by a Wake-Up event on the INTD1 external interrupt channel. The Wake-Up event
can be a rising or a falling event on one of the 16 Wake-Up lines: WKUP[15:0] (Refer to the
Wake-Up / Interrupt Lines Management Unit Chapter of the datasheet).
In the ST92F150, the WKUP6 line is connected on both the CAN0 RX line (or P5.1 in standard
I/O mode) and the CAN1 RX line. This is a useful feature for applications that use the CAN in-
terfaces since an event on the CAN buses will wake-up the microcontroller.
As the ST92F250 includes only one CAN, the WKUP6 line is connected only to the CAN0-RX
(or P5.1 in standard I/O mode) and the pin corresponding to the CAN1 RX line becomes the
standard I/O P6.6.
Application Impact: if an ST92F150 application uses the WKUP6 line on the CAN1 RX line,
this feature is not available on the ST92F250 and the signal must be connected to another
Wake-Up line (or on P5.1 WKUP6).

of the ST92F250 will have different timing characteristics from the ST92F150, and the appli-
cation may have to be adapted by adding some wait cycles (refer to the External Memory
Interface Chapter of the datasheet).
