SRAMBytes

The public SRAMBytes variable is an unsigned 16-bit number that is filled at class instantiation and should not be changed outside of the class.

During class instantiation the actual size of the memory is determined by exploiting the memory wrap-around functionality when writing past the physical end of memory. The value set in SRAMBytes is as follows for the specific models:

Memory Type	Storage Bits	SRAMBytes
23x640	64 kbit	8192 Bytes
23x256	256 kbit	32768 Bytes
23x512 23LCV512	512 kbit	65536 Bytes
23x1024 23LCV1024	1024 kbit	131072 Bytes

###Example

const uint8_t CS_PIN = 8;   // define the CS/SS Pin used for SPI
MicrochipSRAM sram(CS_PIN); // Instantiate the class
uint16_t availableMemory = sram.SRAMBytes;
Serial.print("Available memory is ");
Serial.print(availableMemory/1024);
Serial.println(" Kb.");
