The Microchip PIC16LF1559-I/SS is an 8-bit MCU from the PIC XLP 16F series, built around the PIC core and clocked at 32 MHz.
The part is ROHS3 compliant. For volume requirements or date-code consistency across a production run, submit an RFQ and we will confirm the supply position.
The standard PIC16F1559-I/SS typically operates from a higher minimum voltage (2.0 V or 2.3 V, depending on the specific datasheet revision). Otherwise, the two are pin-compatible and share the same 14 KB Flash, 512-byte RAM, 32 MHz core, and peripheral set. For a 1.8 V rail design, the LF variant is the correct choice.
It is pin-compatible and functionally identical, with the added benefit of operating down to 1.8 V. No board or firmware changes are required.
