Microchip explicitly states the PIC16F877A-I/P is "In Production" with no EOL announcement. The part is widely distributed (LCSC, DigiKey, Mouser), in stock, and maintains errata documentation. A recent PCN was issued in October 2016, and Microchip's corporate policy commits to product longevity for legacy parts like this one, which remains one of the most popular 8-bit microcontrollers despite its age.
