STM32F10xxx FSMC configuration in 100-pin

packages

The FSMC is present in devices delivered in both 144-pin and 100-pin packages. For

devices in 100-pin packages, however, only some FSMC banks can be used because not all

pins are available.

5.1

Interfacing the FSMC with a NAND Flash memory

In devices that come in 100-pin packages, only Bank2 can be used to interface the FSMC

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 9 shows how to connect an 8-/16-bit NAND Flash memory to the FSMC peripheral of

devices delivered in 100-pin packages.
