18 productsAbout 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.

NVIDIA led semiconductor vendor revenue in 2025, while TSMC dominated pure-play foundry sales. This guide explains why those rankings measure different things—and gives engineers and buyers a practical framework for selecting manufacturers by component category, lifecycle, qualification, and supply risk.
DDR4 vs DDR5: Key Differences in Speed, Latency, Power, Capacity, and Compatibility
DDR5 is the newer memory standard, offering higher bandwidth, lower nominal operating voltage, improved module architecture, and better capacity scaling than DDR4. However, DDR4 remains widely used in existing PCs, embedded systems, industrial equipment, and cost-sensitive platforms. The best choice depends on your motherboard, processor, workload, budget, and long-term sourcing requirements.
Circuit Board Component Identification: How to Identify PCB Components by Markings, Shape, and Codes
Circuit board component identification means recognizing PCB parts by their reference designators, physical appearance, body markings, polarity marks, package type, and electrical function. The fastest way to identify a component is to start with the PCB silkscreen, match the reference letter to a component type, inspect its shape and package, read any value or top marking, then confirm the result with a datasheet, schematic, BOM, or measurement tool. This guide explains how to identify common PCB components such as resistors, capacitors, inductors, diodes, transistors, MOSFETs, ICs, connectors, fuses, relays, crystals, and test points. It also includes practical examples, common marking codes, polarity clues, mistakes to avoid, and a replacement sourcing checklist.
IC Top Marking Codes Explained: How to Identify SMD Chips from Package Markings
IC top marking codes are abbreviated package markings used to identify semiconductor devices, especially small SMD chips that cannot fit a full part number. Buyers should use the marking as a starting point, then verify manufacturer logo, package, pin count, date code, lot code, datasheet, packing label, and supplier documentation. Official manufacturer marking tools and datasheets should be used before relying on third-party SMD code databases.
DDR6 RAM: What We Know So Far About Next-Generation Memory
DDR6 RAM is the next planned generation of DDR memory technology after DDR5, designed to support higher bandwidth, improved efficiency, and future computing platforms with greater data movement requirements. Although DDR6 is not yet a mainstream commercial product, major memory manufacturers and platform developers are already preparing for the next stage of DRAM evolution.
How to Find Pin-Compatible Alternatives for Obsolete ICs
Finding a pin-compatible alternative for an obsolete IC is not just about matching the package. It requires a structured review of pinout, footprint, electrical parameters, functional behavior, lifecycle status, sourcing reliability, and sample validation.
Pin-to-Pin Replacement Parts: How to Check Compatibility Before Sourcing
When an original electronic component becomes obsolete, unavailable, or too expensive, a pin-to-pin replacement part can help avoid PCB redesign and keep production or repair projects moving. However, pin-to-pin compatibility does not automatically mean the part is a safe drop-in replacement. This guide explains how to check package, footprint, pinout, electrical ratings, thermal performance, timing behavior, firmware requirements, compliance status, and lifecycle risk before sourcing replacement parts. It also provides a practical checklist to help engineers, buyers, and maintenance teams reduce sourcing mistakes and verify compatibility before purchase.
