About EEPROM

EEPROM (Electrically Erasable Programmable Read-Only Memory) ICs are non-volatile semiconductor memory devices designed to store small amounts of critical data — such as system configuration settings, calibration coefficients, serial numbers, MAC addresses, and user preferences — that must be retained through system power cycles. EEPROMs support byte-level read and write access, offering highly flexible data logging capabilities on PCBs.

EEPROMs are characterized by high endurance (often exceeding 1 million write cycles) and long data retention (typically 40 to 100+ years). Key parameters include memory capacity (ranging from bits to megabits), serial interface protocol (I2C, SPI, or Microwire), operating voltage range, and ultra-low current consumption. Compact packages (including SOIC, TSSOP, DFN, and WLCSP) make them ideal for space-constrained designs.

On Octatronics, source high-quality EEPROMs from leading brands including Microchip Technology, STMicroelectronics, onsemi, and ROHM. Compare specifications, check stock levels, and submit RFQs for volume deliveries.

Frequently Asked Questions

Octatronics can help source a wide range of EEPROM from major manufacturers worldwide, including active production parts, long-lead-time items, and hard-to-find components.

Yes. You can submit a single part number or upload a BOM with multiple parts. Our team will check stock, date code, lead time, and pricing for each item.

Availability depends on the specific part number and supplier source. For important orders, buyers can request packaging photos, labels, date code information, and traceability documents.

Yes. Octatronics supports sourcing for active, end-of-life, obsolete, and hard-to-find components through our global supplier network.

Please provide the part number, manufacturer, quantity, required date code, target price, delivery country, and whether original packaging or COC is required.
