Principio de funcionamiento<\/h2>\n

The S-25C320A0 uses a NOR flash array with multi-I\/O SPI. The device supports standard SPI (1-1-1), dual output (1-1-2), dual I\/O (1-2-2), quad output (1-1-4), and quad I\/O (1-4-4) read commands. At 80MHz quad I\/O, read throughput reaches 40MB\/s. 4KB sector erase enables fine-grained updates. The security register area provides 256 bytes of OTP memory for device serialization. Auto-address increment (AAI) programming simplifies multi-byte write sequences.<\/p>\n
