Overview
The ER2055 is an EEPROM made by Microchip Technology in a DIP-22 package with 22 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:ER2055, from EasyEDA) and its footprint (Package_DIP:DIP-22_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C6613529).
