27C080 8MB CMOS EPROM — Datasheet & Specifications

An EPROM chip is typically a ceramic or plastic DIP (Dual In-line Package) integrated circuit with a distinctive quartz glass window on the top surface. This transparent window allows UV light to reach the silicon die for erasure. The package usually has 28 or 32 pins depending on the density, and the window is often covered with an opaque label during use to prevent accidental data erasure from ambient light.

The 27C080 is an 8-megabit (1M x 8-bit) CMOS UV-erasable EPROM. It features a 32-pin DIP or PLCC package, operates on a 5V supply, and offers access times typically ranging from 70ns to 120ns. It is pin-compatible with the 27C801 and is widely used for firmware storage, boot code, and nonvolatile program memory in embedded and industrial systems.

Leading manufacturers of 27C080 and equivalent 8MB CMOS EPROMs include Sharp Microelectronics (LH57 series), AMD (Am27C series), SGS-Thomson (M27C series), Hitachi (HN27 series), Fujitsu (MBM27C series), NEC (uPD27 series), Cypress Semiconductor, Seeq Technology, and General Instrument. LEVEL SOLUTIONS sources all these brands in commercial and Mil-spec package types.

Yes. LEVEL SOLUTIONS offers both commercial and military-specification (Mil-spec) package types for 27C080 and equivalent EPROMs across all supported manufacturers. Mil-spec versions are tested to more stringent environmental and operational standards, making them suitable for defense, aerospace, and other high-reliability applications requiring extended temperature range and enhanced screening.

EPROMs are sensitive to electrostatic discharge (ESD), which can permanently damage the device. LEVEL SOLUTIONS stores and ships all EPROM components from an ESD-compliant warehouse using proper anti-static packaging, handling procedures, and controlled environments. Components are shipped in conductive foam or anti-static trays to ensure they arrive in full working condition.

Yes. The 27C080 is an industry-standard pinout device widely used for replacing obsolete or end-of-life firmware ROMs in legacy embedded systems, industrial controllers, and vintage computing equipment. LEVEL SOLUTIONS maintains extensive global inventory to support long-lifecycle procurement needs, including one-time builds and ongoing legacy maintenance programs across commercial and military platforms.
