Microchip PIC 16F870-20/P (2k FLASH, 20 MHz, DIP-28)This is a reduced version of the PIC-16F877-DIP (most important: only 2k code, 22 I/O pins), recommended for the final version of a project that does not need the full power of the PIC-16F877-DIP.This chip is in a DIP housing. Suitable sockets are DIP-28-L-(5) (low-cost, flat pins) or DIP-28-Q or (high-quality, round pins)..manufacturer: MicrochipIf you have a .hex file that you want programmed into this chip that is possible for an extra fee. Add PIC-PROGRAMMING to your order, and send me the .hex file by email. Note: the .hex file must be complete, including the configuration fuses.When this standard chip is temporarily not available I might provide you an LF chip (extended opertaing voltage range) or an E version (extended temperature range) instead. Such chips are fully (upwards) compatible replacements for the plain F chips.
