Topics

See Release Information when using the E2 emulator Lite.

The E2 emulator Lite (abbreviated as "E2 Lite") is an on-chip debugging emulator and flash programmer for MCUs of the RX, RA, RE and RL78 families. The E2 Lite is more economical than the E1, and is suitable for work across the whole range from education and initial evaluation to professional development.

Features

  • An entry model recommended for new starters
  • Features equivalent to E1 at a more affordable price
  • Ability to connect to boards designed for E1
  • Support for new MCUs with next-generation, such as RXv3, RA, etc.
