| Market Reality | The PIC16F84A is the microcontroller that taught a generation of designs: an 18-pin workhorse in chargers, timers, industrial retrofits and ten thousand hobby classics, still demanded by field repairs long after new designs moved on. Its living successor is the PIC16F628A - the same 18-pin footprint, a factory-calibrated internal 4MHz oscillator the original never had, USART, PWM and twice the program memory - requiring exactly two kinds of work: two firmware lines that every migration guide names (comparators off, bank layout), and hardware that mostly stays put. Buying this part in 2026 means the aftermarket: date codes, pulls and re-marked stock are the sourcing question, not availability on paper. | The PIC16F84A is the microcontroller that taught a generation of designs: an 18-pin workhorse in chargers, timers, industrial retrofits and ten thousand hobby classics, still demanded by field repairs long after new designs moved on.
