STM32F30xxD/E FMC configuration in 100-pin
packages
The FMC is present in devices delivered in both 144-pin and 100-pin packages. For devices
in 100-pin packages, however, only some FMC banks can be used because not all pins are
available.
5.1
Interfacing the FMC with a NAND Flash memory
In devices that come in 100-pin packages, only Bank2 can be used to interface the FMC
with an 8-/16-bit NAND Flash memory. This is because the NCE3 pin is not available in
these packages.
Likewise, no interrupt can be used because the two interrupt pins INT2 and INT3 are not
available in 100-pin packages.
Table 10 shows how to connect an 8-/16-bit NAND Flash memory to the FMC peripheral of
devices delivered in 100-pin packages.
