27C128-15I/K

Overview

The 27C128-15I/K is a 131,076-bit (16K x 8) UV-Erasable Programmable Read-Only Memory (EPROM) manufactured by Microchip Technology. It features a parallel interface with a maximum access time of 150 ns and operates on a single 5V power supply. The device is housed in a 28-pin PLCC package and supports industrial temperature ranges from -40°C to +85°C. Data retention is specified for ten years without power.

Feature Summary

Supports UV erasure for reprogrammability via a dedicated window.

Applications

Embedded firmware storage in industrial control systems.

Procurement Notes

Verify the integrity of the quartz window on the component surface prior to installation, as exposure to ambient light can cause data loss. Confirm that the specific ordering suffix matches the required package type and temperature grade. Ensure compatibility with existing programming equipment for EPROM architectures before procurement.

Selection Notes

Select this component when non-volatile storage requiring field reprogramming via ultraviolet light is necessary. It serves as a legacy alternative to flash memory in systems designed around parallel ROM interfaces. Consider the physical requirement for a UV eraser unit during the development and maintenance phases of the product lifecycle.

Part Context

This part belongs to the 27C series of high-speed EPROMs, representing a transition from older OTP ROMs to fully erasable and reusable memory solutions. It maintains pin compatibility with earlier generations while offering improved speed and reliability characteristics suitable for demanding industrial environments.

Replacement Considerations

Direct replacements include the AT27C128-15PC or other 27C128 variants from Microchip. Verify package equivalence between PLCC and DIP formats if mechanical constraints differ.
