2.20 NOR Flash
128 Mbit NOR Flash is connected to bank1 NOR/PSRAM2 of the FSMC interface. The 16-
bit operation mode is selected by a pull-up resistor connected to the BYTE pin of the NOR
Flash. Write protection can be enabled or disabled by jumper JP5.
Three different NOR 128-Mbit references can be present on the evaluation board depending
on component availability.
These three references are not identical in terms of ID code, speed, timing or block
protection. The demonstration firmware and the software library delivered with the board
support these three NOR Flash references. However, during the development of your
application software, you must verify which NOR reference is implemented on your board
(component referenced as U2 on silkscreen and schematic), and take its characteristics into
account.

Jumper Description
JP5 Write protection is enabled when JP5 is fitted while write protection is
disabled when JP5 is not fitted.
Default setting: not fitted

3.8 Daughter board extension connectors CN10 and CN11
Two 70-pin male headers CN10 and CN11 can be used to connect a daughter board or
standard wrapping board to the STM3210E-EVAL evaluation board. All total 112 GPI/Os are
available on it. The space between these two connectors and the position of power, GND
and RESET pins (marked in gray in Table 23 and Table 24) are defined as a standard which
allows to develop common daughter boards for several evaluations boards. The standard
width between CN10 pin1 and CN11 pin1 is 2700 mils (68.58 mm). This standard is
implemented on the majority of evaluation boards.
Each pin on CN10 and CN11 can be used by a daughter board after disconnecting it from
the corresponding function block on the STM3210E-EVAL evaluation board, as described in
Table 23 and Table 24.
