SPLatco Knowledge Base

Shadow memory in the SL100 is implemented using a byte erasable EEPROM memory. Endurance is 10,000 writes or clears total (across all bytes). ShadowWrite takes up to 20mS per byte. ShadowClear takes up to 10mS per byte. During these times the SPLat processor can do nothing else (for example quadrature counting). We use a smart algorithm to avoid redundant writes and clears, making the process as fast as possible and reducing wear on the memory.

ShadowRead is very fast.
