OTP EPROM Memory Chips | Supplier & Distributor

EPROM stands for Erasable Programmable Read-Only Memory. It is a type of nonvolatile memory that can be programmed electrically and erased by exposure to ultraviolet (UV) light through a quartz window on the chip package. EPROMs are commonly used for firmware, boot code, and embedded program storage.

In embedded systems, OTP (One-Time Programmable) refers to memory that is written once during manufacturing or field programming and cannot be altered afterward. OTP memory is used to store firmware, boot code, and configuration data in applications where the code is finalized, offering a cost-effective and secure alternative to fully erasable EPROMs.

LEVEL SOLUTIONS stocks EPROM and EEPROM chips from a broad range of manufacturers including AMD, NEC, Hitachi, Fujitsu, Sharp Microelectronics, SGS-Thomson, Cypress Semiconductor, WaferScale Integration, MMI, Seeq Technology, General Instrument, Microchip Technology, and NXP Semiconductors, in both commercial and Mil-spec package types.

Yes. LEVEL SOLUTIONS supplies EPROM and EEPROM memory chips in military-specification (Mil-spec) package types across all major manufacturers. Mil-spec components are available for defense, aerospace, and high-reliability industrial applications, and all parts are stored in ESD-compliant facilities to maintain component integrity.

EPROM chips are used in embedded firmware and boot-code storage, industrial control systems, computing system BIOS, legacy microprocessor systems, lookup tables, address decoding, military-spec equipment, prototype development, and consumer electronics program memory. Both UV-erasable and OTP variants serve production and development use cases across commercial and defense markets.

All EPROM and EEPROM components at LEVEL SOLUTIONS are stored in ESD-compliant warehouses to prevent electrostatic discharge damage. Parts ship from local inventory with millions of components available for immediate dispatch. Billions of additional parts can be sourced globally. Specific shipping methods and return policies are available upon request.
