The 2 MHz clock frequency sets the read/write throughput ceiling; each write cycle takes 5 ms (word or page). This density tier is typical for storing calibration constants, serial numbers, or a small configuration block in industrial control, telecom, or sensor modules. The 8-UFDFN with exposed pad (2x3 mm body) saves board area on compact designs; the thermal pad should be stitched to a ground plane with vias to pull heat out of the package during sustained write cycles. For dual-sourcing or a density upgrade, the AT93C56B-SSHM-B (2 Kbit, same 3-wire interface, SOIC-8) is a functional step-up, though the package differs.","metaTitle":"AT93C46DY6-YH-E EEPROM 1Kbit 3-Wire Serial 2MHz 8-UDFN","metaDescription":"Microchip AT93C46DY6-YH-E 1Kbit serial EEPROM, 1.8V-5.5V supply, 2 MHz clock, 8-UDFN (2x3mm) package.
