This new product serves as a replacement for both E-PGM+ and E-PGM Serial, and it extends support to microcontrollers with Flash memory larger than 1 MB, which were not supported by E-PGM+.

By adopting a high-performance controller, the E-PGM-LC significantly improves write speed. In addition, it employs a WinUSB driver, enabling immediate use without Windows driver installation.

The E-PGM-LC programmer also supports 5 V USB portable power, allowing it to be used as a mobile programmer. An additional Power MOSFET has been incorporated into the output voltage circuit to enhance durability and reliability.

The table below compares E-PGM-LC with existing products.
