ABB 2764-3EPROM8K8ABB 2764-3EPROM8K8 Industrial EPROM Memory Spare Part
Full Official OEM Name: ABB 2764-3EPROM8K8 8K×8-Bit UV-Erasable Programmable Read-Only Memory Industrial Firmware Chip (DIP-28 Legacy Control System EPROM Module) Core Function: This dedicated industrial-grade 2764 EPROM IC stores factory core firmware, control logic programs, parameter calibration data, and fault lookup tables for legacy ABB PLC, DC drive, and early DCS rack CPU boards. The 8K×8 bit memory array retains data without continuous power supply via floating-gate transistor storage. It is UV-erasable through a quartz window for firmware re-flashing during equipment overhaul, delivers stable 5V logic-level data read operations to host microprocessors, and serves as a critical pluggable spare for vintage ABB industrial control hardware phased out of active OEM production. It pres
