Product details

2Kbit I²C EEPROM in a DIP-8 — the board-fit story

The 85C82E/P is a 2Kbit serial EEPROM organized as 256 x 8 bits, communicating over an I²C bus at up to 100 kHz. The 8-pin DIP package (0.300-inch row spacing) drops into a standard through-hole footprint — no reflow profile needed, just a wave or hand-solder station. For a legacy board or a low-volume build where you want to avoid the NRE of a stencil, this package saves a spin.

Supply rails and temperature grade

Runs on a single 4.5V to 5.5V rail — the classic 5V ±10% logic supply. The -40°C to 125°C operating range covers automotive under-hood and industrial oven-adjacent environments; the 125°C ceiling means the EEPROM retains data through a hot reflow or an engine-bay soak that would push a commercial-grade part past its limit.

Active lifecycle and what it means for BOM planning

The part is RoHS non-compliant, so if your BOM requires RoHS-10 exemption or you're building for a market that still accepts leaded solder (military, aerospace, some industrial), this fits.

Frequently asked questions

Will 85C82E/P drop into a board that was specified around AT24C08D-PUM without rewiring?

Not without a board spin. The AT24C08D-PUM is an 8Kbit EEPROM in an 8-pin DIP with the same I²C interface and 1.8V supply, but the 85C82E/P runs at 4.5-5.5V only and holds 2Kbit — four times less memory. The pinout is compatible, but the supply voltage and memory map differ. A firmware change and a rail adjustment would be needed.

What compliance documentation does Microchip Technology provide for 85C82E/P?

The part is RoHS non-compliant per Microchip's listing. For compliance certificates, request them at RFQ time.
