Product details

What this 2 Kbit I²C EEPROM brings to a BOM

The Microchip 34AA02-I/P is a 2 Kbit serial EEPROM organized as 256 x 8 bits, accessed over an I²C bus at up to 400 kHz. It stores configuration parameters, calibration constants, or small lookup tables in designs where non-volatile memory is needed but the density requirement stays modest. The 8-DIP through-hole package (0.300" body) is the go-to form factor for breadboarding, legacy board rework, and low-volume production where socketing or hand-soldering is the norm.

The 900 ns access time at 400 kHz leaves setup margin before the next SCL edge.

The through-hole PDIP package is not the first choice for high-vibration environments — a socket with a retention clip or conformal coating helps — but for benchtop instrumentation, HVAC controllers, and retrofit boards it is exactly what the rework tech wants to see.

Microchip lists the 34AA02-I/P as Active. The ROHS3 compliance covers current EU and UK regulatory requirements without an exemption expiry.

Frequently asked questions

What are the cross-reference alternatives to 34AA02-I/P?

The closest functional alternative in a through-hole DIP package is the 24AA01-I/P (1 Kbit, same I²C interface, same supply range and temperature grade). The 24AA01-I/P halves the density to 128 x 8 and has a longer access time of 3500 ns, so a firmware change to the memory map and a timing review are needed. For a drop-in 2 Kbit replacement, the AT34C02C-THDD-T matches the density and access time but comes in a surface-mount package — not a pin-compatible swap for the 8-DIP footprint.
