Description
AMD AM27C2048 15000 EPROM 2Mb UV Erasable Memory IC DIP-40 Vintage 1997 Chip
The AMD AM27C2048 is a 2 Megabit (256K x 8) UV-erasable CMOS EPROM housed in a 40-pin DIP ceramic package. This unit is marked AM27C2048-150DC, indicating a 150 ns access time and commercial temperature range. The visible date code 9818 places manufacture in week 18 of 1997. Like all EPROMs of this family, it is erased by exposure to UV light through the quartz window on the package top, and can be reprogrammed using a standard EPROM programmer.

Applications
The AM27C2048 belongs to AMD's 27C-series EPROM family, a line of UV-erasable programmable read-only memory devices that were widely used from the mid-1980s through the late 1990s in embedded systems, industrial controllers, telecommunications equipment, arcade game boards, automotive electronics, and computer BIOS storage. The 2 Megabit capacity and 40-pin DIP form factor made it a common choice for firmware and lookup-table storage in equipment that required field reprogrammability without battery-backed SRAM. Today these chips remain in demand for maintaining, repairing, and cloning legacy embedded systems, vintage computers, and industrial control boards that cannot be upgraded to newer flash-based storage. Compatible programmers include devices supporting the standard 27C-series EPROM protocol, and the chip is pin-compatible with many 27C020 equivalents from other manufacturers including Intel, Atmel, and ST Microelectronics.
This AMD AM27C2048-150DC EPROM IC has been inspected and is in good condition. It was pulled from a working environment where it was previously in use. The chip body shows no physical damage, and the 40 DIP pins appear straight and intact. The UV erase window is intact. The unit is stored in an anti-static tray within a cardboard box as shown in the photos. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
