EPROM
EPROM (Erasable Programmable Read-Only Memory) ICs store firmware and configuration data that can be erased by UV light exposure and reprogrammed. While largely superseded by Flash memory in new designs, EPROMs remain in production for legacy system maintenance in military, aerospace, and industrial applications.

82,970 productsAbout EPROM
EPROM (Erasable Programmable Read-Only Memory) ICs are non-volatile memories designed to store firmware and system boot code. EPROMs are characterized by their floating-gate transistor arrays which can be erased by exposing the silicon die to ultraviolet (UV) light through a quartz window on the package, allowing them to be reprogrammed. While largely superseded by Flash memory and EEPROM in new designs, EPROMs remain in active production to sustain critical legacy hardware in military, aerospace, and industrial installations.
Selection of EPROM components for maintenance and legacy repair depends on memory density, access times (nanoseconds), programming voltage (Vpp), package footprint (typically Ceramic DIP or LCC with quartz windows), and lifecycle availability.
On Octatronics, source high-quality replacement EPROMs from legacy semiconductor suppliers including Microchip Technology, STMicroelectronics, and Rochester Electronics. Verify component authentication, package styles, and submit your RFQ online.
Frequently Asked Questions
Octatronics can help source a wide range of EPROM 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.
