PIC16F84A-20I/SO 8-bit MCU for embedded control

This PIC16F84A-20I/SO is an 8-bit microcontroller in an 18-pin SOIC package. It suits engineers and hobbyists building compact embedded systems that need simple I/O control. The device operates at speeds up to 20 MHz. It is sold as a new semiconductor component.

SOIC-18 package enables surface-mount assembly

The SOIC-18 footprint allows direct placement on printed circuit boards without through-hole drilling. This reduces board size and supports automated soldering workflows. No additional accessories or software are included with the IC. Buyers needing a different pin count or package style should select another part.

Questions about this item

Does the SOIC-18 package require any special handling or replacement considerations during board assembly?

The SOIC-18 surface-mount package uses standard reflow soldering profiles. No special handling beyond typical ESD precautions for CMOS devices is needed, and the part is not socketed for field replacement.

What thermal or voltage limit is reached first when the MCU runs continuously at 20 MHz?

The 20 MHz rating defines the maximum clock speed; sustained operation at this frequency stays within the specified industrial temperature and supply-voltage ranges without exceeding internal timing margins.
