Clock frequency is 2 MHz, and the write cycle time per word or page is 6 ms — the limiting factor for firmware update throughput is this write time, not the bus clock. Product status is Active, meaning Microchip Technology continues to manufacture and support this part for new designs. ROHS3 compliant, so it meets the current EU restriction on hazardous substances without exemption.","metaTitle":"Microchip 93AA56AT-I/SN 2 Kbit Microwire EEPROM, 2 MHz","metaDescription":"Microchip Technology 93AA56AT-I/SN 2 Kbit EEPROM, Microwire interface, 2 MHz clock, 1.8-5.5 V supply, 8-SOIC, -40 to 85°C.
