PIC16x84

The PIC16C84, PIC16F84 and PIC16F84A are 8-bit microcontrollers of which the EEPROM based PIC16C84 was the first introduced in March 16 1993 at the suggested retail price of $3.72 in quantities of 10,000.

Software tools for assembler, debug and programming were only available for DOS[2]: PICSTART-16C [3]: MPALC [3]: MPSIM  and Microsoft Windows 3.X operating systems.

Both "EEPROM" and "FLASH" utilise similar forms of "floating gate" technologies to operate.

Microchip's product line has gone through many revisions since the 16x84 and more powerful, flexible, cheaper pin-compatible PICs have been developed.

Existing PIC 16x84 code may require some modifications for these variants, namely making sure pins with multiple functions have been set up properly.
