1 OVERVIEW
EVB-I94124ADI is the specific development tool for I94100 series. User can use EVB-I94124ADI to
develop and verify the application program easily.
EVB-I94124ADI includes two portions. One is I94124ADI evaluation board and the other is Debug
Adaptor (Nu-Link-Me). Thus, users do not need other additional ICE or debug equipment.
Introduction to EVB-I91240ADI Board1.1
EVB-I94124ADI uses the I94124ADI as the target microcontroller. The EVB-I94124ADI board consists
of I94124ADI Platform and Nu-Link-Me ICE Bridge. Figure 1-1 shows the EVB-I94124ADI board.
The left portion of this board is the I94124ADI Platform that includes the target chip I94124ADI MCU
which embedded ARM® Cortex®-M4 core with DSP extensions and a Floating Point Unit (FPU) and the
other related on-board application parts and connectors.
The right portion of this board is a Nu-Link-Me ICE Bridge based on the SWD (Serial Wire Debug)
interface connected with the target chip, allowing user to program the application code to the flash of
target chip through the USB port from PC Host.

Power Supply2.3
The EVB-I94124ADI supplied by an external 5 Volt DC power supply connected to Micro USB
connectors (CN1 and CN2) or 1.6 Volt to 3.6 Volt DC power supply connected to Pin Header (JP2).
On-board reverse current protection diodes will ensure safe operation in case power is provided
through both USB connectors at the same time. If the board is powered via a USB connector, it is not
recommended to apply an additional power supply to VCC pin header (JP2), because there is no
protection against reverse current into the external power supply. Figure 2-3 shows EVB-I94124ADI
power supply concept.
