EEPROM Programmers
Reliable programmers for serial EEPROMs supporting I²C, SPI, and Microwire.
Designed for fast production, lab evaluation, and field service.
EPW-20A Serial EEPROM Programmer
The EPU-20A is a versatile programmer designed for serial EEPROMs.
It connects to a PC via a USB Type-C interface and works with dedicated software to read and write various types of EEPROM devices.
Supporting Microwire, SPI, and I²C protocols, the EPU-20A is compatible with a wide range of 8-pin EEPROMs from major manufacturers.
With the optional ISP (In-System Programming) connector, it can also program devices mounted directly on circuit boards.
The EPU-20A utilizes a parameter database tailored to each manufacturer’s device, ensuring optimal programming conditions.
An optional editing tool allows users to customize and extend the database to suit specific needs.
Equipped with Lua scripting capabilities, the EPU-20A can be controlled via user-defined scripts for advanced automation.
Lua scripts can also run independently, enabling users to build custom applications around the programmer.
Thanks to its compact design, intuitive operation, and powerful customization features, the EPU-20A is ideal for production, evaluation, and field maintenance applications.
