Features

E1/E20 Emulator is an on-chip debug emulator with flash programming function, which is used for debugging and programming a

program to be embedded in on-chip flash memory microcontrollers. This product can debug with the target microcontroller connected to

the target system, and can write programs to the on-chip flash memory of microcontrollers.
