Chapter 1 Overview
1.1 Purpose
The DK-S124 is a development kit for the Renesas SynergyTM S124 microcontroller in a LQFP64 package. The
DK-S124 is primarily intended for software and hardware developers to develop firmware, experiment, and
evaluate the I/O features of the S124 on the DK-S124 prior to development of their own customized hardware.
The DK-S124 contains several communications ports, including Bluetooth Low Energy, CAN, RS-232/RS-485, SPI,
I2C, and USB Device. The board includes a PMOD™ connector and a Grove I2C connector (connector for easy-touse Seeed Grove modules), for external prototyping modules from Digilent and other vendors.
For HMI interface examples, the DK-S124 include stereo headphone output, microphone input, touch buttons and
a touch bar, two user-programmable push-buttons, three user programmable LEDs, a thumb-wheel potentiometer,
light sensor, temperature sensor, and 3-axis accelerometer.
Several test points are located around the board, and jumpers are provided for measurements and configuration.
The DK-S124 is supported by both the e
2
studio from Renesas and the IAR embedded workbench for Synergy.

Getting Started
Chapter 2 Getting Started
The DK-S124 includes the Main Board assembled with bumper feet and an acrylic cover over the touch region, a
PMOD serial LCD daughter card, a 3-foot (91-cm) USB Type A to Micro-B adapter cable, and a Quick Start Guide.
To start working with the DK-S124, see the included Quick Start Guide.
Figure 3: DK-S124
2.1 Powering the DK-S124
Prior to providing power with one of the three power options, make sure that the power jumpers in the BATTERY
labeled region of the DK-S124 main board are properly installed. For non-battery operation, and without an
ammeter installation, J3, J19, and J20 should all have jumpers installed across their two pins. Also, the two
SOURCE SELECT header jumpers, J2 and J18, should have a total of three jumpers installed from their center
terminal to their left-most terminal for each row of terminals.
The DK-S124 can be powered via three different methods:
• 5-V power source at the -5V external power connection, J1, on the DK-S124 main board. Note that the
outer sleeve of the barrel connector must be negative, and the center of the connector must be positive.
• External USB host to the J-Link USB connector, J14, on the DK-S124 main board.
• CR2032 coin cell battery in the BAT1 holder on the DK-S124 main board. Note that this option may
require one of the other two listed power sources also be installed for proper operation of the J-Link
interface, which may affect reboot of the S124 processor. For proper operation and use of the coin cell
battery, jumpers on J2 and J18 may need be changed to jump the center terminal to the right-most
terminal, and J19 and J20 may or may have jumpers installed between their terminals (removal of the
jumper unpowers the circuitry served by J19 or J20).

barrel plug power source may permanently damage the unit.
Getting Started
If power is supplied from the 5-V barrel connector, a green LED should be lit in LED4 making that LED green. If
power is from the USB port, both LED4 LEDs are lit on J-Link MCU commands making LED4 appear orange. LED4 is
located in the box labeled “POWER” on the DK-S124. LED4 is not powered by the coin cell with jumpers properly
installed.
If both the barrel connector is powered, and the J-Link USB port is powered, LED4 will change to orange on J-Link
MCU commands and power from the DK-S124 will be taken from the source with the higher voltage, or shared if
the loaded higher-voltage source voltage droops to the open-circuit voltage of the other source.
There is limited voltage protection on the 5-V direct power input. Using a reverse-polarity

A demo (pre-installed on the DK-S124) will start up when the unit is first powered. If during the course of
software development this demo is erased from the flash memory you can download this demo from the

Micro-B cable, and the Segger J-Link On-Board debugger USB interface.

Power Supplies
Chapter 3 Power Supplies
3.1 Power supply
Power may be supplied to the DK-S124 from three sources:
• The barrel jack J1 in the upper left corner of the circuit board, with +5 V to the center of the
mating plug and 0 V to the outer sleeve of the mating plug
• The USB Micro-B J-Link jack J14 adjacent to the battery holder
• A CR2032 lithium coin cell installed in BAT1 holder near the right edge of the circuit board
When power to the S124 MCU is supplied from the lithium coin cell, power from one of the other
two sources should be available to power the J-Link and related support circuitry. This will allow
proper restarting of the S124 MCU.
3.2 Power-up behavior
The DK-S124 is delivered preloaded with a demonstration program. The demonstration program shows several
features of the DK-S124 and source code is available as a programming example for developers. See the Quick
Start Guide delivered with the DK-S124 for details of use of and expected board behavior when running the
demonstration program.
When powered from J-Link USB or the barrel jack, the green LED in LED4 adjacent to the barrel jack will be lit. The
red LED in LED4 will be controlled by the J-Link microcontroller in accordance with J-Link specifications. When
both LEDs are lit, LED4 will appear orange.
3.3 Battery supply configuration
See Chapter 6 for configuration details.
3.4 +5-V Main Voltage Rail
Dual low-drop Schottky diodes merge the two power inputs (barrel connector input and J-Link USB supply) so
that whichever is available and higher is delivered downstream as the power rail
circuitry on the DK-S124.

Figure 5: +5V Main Rail Schematic Extract
3.5 3.3-V Main Power Subsystem
Almost all the circuits on the board require 3.3 volts, including MCU, memory, and logic. The +5-V Main Voltage
Rail power is delivered to the ISL91107 buck-boost switcher. This switcher, using a tiny inductor, creates 3.3 V at
up to 2 A to the DK-S124. It can operate with +5-V rail voltage between about 5.8 V and about 2 V. The variant of
the switcher shown is internally set for FB pin voltage of 3.3 V.
Figure 6: 3.3V Regulator Schematic Extract
3.6 Power LED
LED4 on the DK-S124 indicates the currently used source of power on the system. LED4 has two LEDs in one
package (red, green) so three colors can be visible: red, green, and orange (when both are lit).
When the green portion of LED4 is lit, the 3.3-V Main Power Subsystem is currently under power. The J-Link MCU
controls when the red portion of LED4 is lit.
