Overview
The 93LC66AT/ST is an EEPROM made by Microchip Technology in a TSSOP-8 package with 8 pins. -40℃~+85℃ 1,000,000 cycles 2.5V~5.5V 200 Years 3MHz 4Kbit 6ms Built-in write enable latch (WEL)、Power-down/Power-up protection circuit SPI TSSOP-8 EEPROM ROHS.
PCBKit's library has its KiCad symbol (Memory_EEPROM:93LCxxA, from KiCad's library) and its footprint (Package_SO:TSSOP-8_4.4x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2062641).
