This is the successor of the 18F452, for instance with a much faster A/D converter. This is the SMD version.
When this standard chip is temporarily not available I might provide you an LF chip (extended opertaing voltage range) or an E version (extended temperature range) instead. Such chips are fully (upwards) compatible replacements for the plain F chips.Related products:
