SAM3X/A
1.1 Configuration Summary
The SAM3X/A series devices differ in memory sizes, package and features list. Table 1-1 below
summarizes the configurations.
Notes: 1. 4 Kbytes RAM buffer of the NAND Flash Controller (NFC) which can be used by the core if not
used by the NFC
2. One channel is reserved for internal temperature sensor
3. 2 / 8 + 4 = Number of SPI Controllers / Number of Chip Selects + Number of USART with SPI
Mode
4. 9 TC channels are accessible through PIO
5. 6 TC channels are accessible through PIO
6. 3 TC channels are accessible through PIO
7. USART3 in UART mode (RXD3 and TXD3 available)
