(1)
1. 64 KB RAM for 256 KB Flash are available on devices delivered in CSP packages only.
2. For the LQFP100 and BGA100 packages, only FSMC Bank1 and Bank2 are available. Bank1 can only
support a multiplexed NOR/PSRAM memory using the NE1 Chip Select. Bank2 can only support a 16- or
8-bit NAND Flash memory using the NCE2 Chip Select. The interrupt line cannot be used since Port G is
not available in this package.
3. The SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the
I

S audio mode.
