Overview of E1/E20/E2 Emulator and E2 emulator Lite

In this document, we describe 'E2 Emulator' as 'E2', 'E1 Emulator' as 'E1', 'E20 Emulator' as 'E20' and
'E2 emulator Lite' as 'E2 Lite'.
The E1, E20, E2, and E2 Lite are on-chip debugging emulators for Renesas' mainstream MCUs.
The E1 and E2 Lite are highly affordable development tools providing basic debugging functions. The
E20 is a development tool allowing sophisticated debugging through enhanced functions such as
tracing and RAM monitoring as well as the basic debugging functions of the E1 and E2 Lite. The E2 is a
development tool providing a solution for the tuning of current consumption and an external trigger
function as extended functions beyond the basic debugging functions of the E1 and E2 Lite. The
E1/E20/E2/E2 Lite can also serve as a Flash Programmer.

Note on Using E20

The large trace function and the real-time RAM monitoring function, which are the primary features of
the E20, cannot be used with RL78 devices.
The available functions are equivalent to those of the E1/E2 Lite (only the internal trace function in the
MCU and memory reference and modification during execution).
The power supply function from the E20 is not supported.
