The 2 MHz clock frequency supports moderate-speed parameter storage in embedded control applications. ## Package and board integration — 8-UFDFN with exposed pad Housed in an 8-UFDFN Exposed Pad package (supplier device package 8-Mini Map 2x3 mm), the part requires a surface-mount footprint with a thermal pad for heat sinking. The exposed paddle must be soldered to a PCB copper plane to meet the datasheet thermal resistance. ## Write cycle and endurance for field updates This is fast enough for infrequent calibration or configuration updates in a production test sequence. The 3-wire serial interface (chip select, clock, data I/O) is compatible with standard SPI-like controllers; no pull-up resistors are required on the data line if the master drives it actively. ROHS3 compliant — no restricted substances above the threshold per EU Directive 2015/863.","metaTitle":"AT93C56B-MAHM-T EEPROM 2Kbit 3-Wire 2MHz Microchip","metaDescription":"AT93C56B-MAHM-T EEPROM 2Kbit, 3-Wire Serial, 2 MHz, 1.7V-5.5V, -40°C to 85°C, 8-UFDFN.
