29 / 31 page  AN2784 STM32F10xxx FSMC configuration in 100-pin packages Doc ID 14779 Rev 4 29/31 5.2 Interfacing the FSMC with a NOR Flash memory In devices that come in 100-pin packages, only Bank 1 (NOR/PSRAM 1) can be used to interface with a NOR Flash memory. This is because the NE2, NE3 and NE4 pins are not available in these packages. Likewise, the A0-A15 pins are not available, so the NOR Flash controller should be used in multiplexed mode to use the databus for both address and data. In 8-bit muxed mode, the FSMC address signals A[15:8] are avaialble on the AD[15:8] pins. Table 10 shows how to connect a NOR Flash memory to the FSMC peripheral of devices delivered in 100-pin packages. Table 10.
