2Kbit I²C EEPROM with wide supply range
The Microchip AT34C02C-THDD-T is a 2Kbit serial EEPROM with an I²C interface, organized as 256 x 8 bits. The 400 kHz clock frequency and 900 ns access time cover the read timing needs of most microcontroller buses. The 8-TSSOP package (4.40 mm width) is a compact surface-mount footprint suited for space-constrained PCBs in industrial control, telecom, and sensor modules.
The 900 ns access time is the read-cycle ceiling from address to data valid. At 400 kHz I²C, the bus period is 2.5 µs, so the access fits within a single clock cycle with margin. This matters if you are back-to-back reading sequential bytes in a tight polling loop — the EEPROM will not stretch the clock beyond the standard timing budget.
The 8-TSSOP package is a standard JEDEC footprint shared with many other 8-pin serial EEPROMs, so board layout reuse across alternate parts is straightforward.
