| FFF Compatibility | Identical 8-pin package layout and pin-to-pin assignments.Same TSSOP-8/MSOP-8 physical dimensions.Direct functional second-source with identical register set and electrical characteristics. | Identical physical pin configuration on the TSSOP-8 footprint.Matches the same TSSOP-8 (SOT505-1) mechanical envelope.Register map differs from the PCF8563, requiring minor driver updates, and the CLKOUT pin is push-pull rather than open-drain. | ||
 AI Summary | PCF8563TS by UMW: Real Time Clock (RTC) IC Clock/Calendar I2C 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). | The NXP PCF8563TS/5,118 is the original, industry-standard implementation of the PCF8563 RTC. It serves as a direct, seamless drop-in replacement with complete physical, electrical, and register-level software compatibility.
| The PCF85063ATT/AJ is NXP's recommended modern successor to the PCF8563 series. While it matches the footprint and physical pins perfectly, it requires minor firmware changes due to a redesigned register map.
