General Precautions in the Handling of Microprocessing Unit and Microcontrolle r
Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas. For detailed usage notes on the
products covered by this document, refer to the relevant sections of the document as well as any technical updates that have been issued for the products.
1. Precaution against Electrostatic Discharge (ESD)
A strong electrical field, when exposed to a CMOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps
must be taken to stop the generation of static electricity as much as possible, and quickly dissipate it when it occurs. Environmental control must be
adequate. When it is dry, a humidifier should be used. This is recommended to avoid using insulators that can easily build up static electricity.
Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and
measurement tools including work benches and floors must be grounded. The operator must also be grounded using a wrist strap. Semiconductor
devices must not be touched with bare hands. Similar precautions must be taken for printed circuit boards with mounted semiconductor devices.
2. Processing at power-on
The state of the product is undefined at the time when power is supplied. The states of internal circuits in the LSI are indeterminate and the states of
register settings and pins are undefined at the time when power is supplied. In a finished product where the reset signal is applied to the external reset
pin, the states of pins are not guaranteed from the time when power is supplied until the reset process is completed. In a similar way, the states of
pins in a product that is reset by an on-chip power-on reset function are not guaranteed from the time when power is supplied until the power reaches
the level at which resetting is specified.
3. Input of signal during power-off state
Do not input signals or an I/O pull-up power supply while the device is powered off. The current injection that results from input of such a signal or I/O
pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal
elements. Follow the guideline for input signal during power-off state as described in your product documentation.
4. Handling of unused pins
Handle unused pins in accordance with the directions given under handling of unused pins in the manual. The input pins of CMOS products are
generally in the high-impedance state. In operation with an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of
the LSI, an associated shoot -through current flows internally, and malfunctions occur due to the false recognition of the pin state as an input signal
become possible.
5. Clock signals
After applying a reset, only release the reset line after the operating clock signal becomes stable. When switching the clock signal during program
execution, wait until the target clock signal is stabilized. When the clock signal is generated with an external resonator or from an ext ern al osci ll at or
during a reset, ensure that the reset line is only released after full stabilization of the clock signal. Additionally, when switching to a clock signal
produced with an external resonator or by an external oscillator while program execution is in progress, wait until the target clock signal is stable.
6. Voltage application waveform at input pin
Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the CMOS device stays in the area between V
(Max.) and V
input level is fixed, and also in the transition period when the input level passes through the area between V
7. Prohibition of access to reserved addresses
Access to reserved addresses is prohibited. The reserved addresses are provided for possible future expansion of functions. Do not access these
addresses as the correct ope ration of the LSI is not guaranteed.
8. Differences between products
Before changing from one product to another, for example to a product with a different part number, confirm that the change will not lead to problems.
The characteristics of a Microprocessing unit or microcontroller unit products in the same group but having a different part number might differ in terms
of internal memory capacity, layout pattern, and other factors, which can affect the ranges of electrical characteristics, such as characteristic values,
operating margins, immunity to noise, and amount of radiated noise. When changing to a product with a different part number, implement a system
evaluation test for the given product.

4.3 Jumper Settings
Two types of jumpers are provided on the EK-RA2E1 board.
1. Copper jumpers (trace-cut type and solder bridge type)
2. Traditional pin header jumpers
The following sections describe each type and their default configuration.
4.3.1 Copper Jumpers
Copper jumpers are of two types, designated trace-cut and solder-bridge.
A trace-cut jumper is provided with a narrow copper trace connecting its pads. The silk screen overlay
printing around a trace-cut jumper is a solid box. To isolate the pads, cut the trace between pads adjacent to
each pad, then remove the connecting copper foil either mechanically or with the assistance of heat. Once
the etched copper trace is removed, the trace-cut jumper is turned into a solder-bridge jumper for any later
changes.
A solder-bridge jumper is provided with two isolated pads that may be joined together by one of three
methods:
• Solder may be applied to both pads to develop a bulge on each and the bulges joined by touching a
soldering iron across the two pads.
• A small wire may be placed across the two pads and soldered in place.
• A SMT resistor, size 0805, 0603, or 0402, may be placed across the two pads and soldered in place. A
zero-ohm resistor shorts the pads together.
For any copper jumper, the connection is considered closed if there is an electrical connection between the
pads (default for trace-cut jumpers.) The connection is considered open if there is no electrical connection
between the pads (default for the solder-bridge jumpers.)
Figure 6. Copper Jumpers
4.3.2 Traditional Pin Header Jumpers
These jumpers are traditional small pitch jumpers that require an external shunt to open/close them. The
traditional pin jumpers on the EK-RA2E1 board are 2 mm pitch headers and require compatible 2 mm shunt
jumpers.
4.3.3 Default Jumper Configuration
The following table describes the default settings for each jumper on the EK-RA2E1 board. This includes
copper jumpers (Ex designation) and traditional pin jumpers (Jx designation.)
The Circuit Group for each jumper is the designation found in the board schematic (available in the Design
Package). Functional details for many of the listed jumpers may be found in sections associated with each
functional area of the kits.

5.1 Power
The EK-RA2E1 kit is designed for +5 V operation. An on-board Low Dropout Regulator (LDO) is used to
convert the 5 V supply to a 3.3 V supply. The 3.3 V supply is used to power the RA MCU and other
peripheral features.
5.1.1 Power Supply Options
This section describes the different ways in which EK-RA2E1 kit can be powered.
Figure 8. Power Supply Options
5.1.1.1 Option 1: Debug USB
5 V may be supplied from an external USB host to the USB Debug connector (J10) labelled DEBUG on the
board. Power from this source is connected to the Main System 5 V Power. Reverse current protection is
provided between this connector and the Main System 5 V Pow er .
5.1.1.2 Option 2: 5 V Test Points
5 V may be supplied from an external power supply to test points on the board. TP7 (5 V) and TP9 (GND)
are loop-style test points, and TP5 (5 V) and TP6 (GND) are large via style test points. The two types of test
points are electrically equivalent, and both are provided for user convenience. Power from this source is
connected to the Main Syst em 5 V Power. Reverse current protection is provided between the 5 V test points
and the Main System 5 V Power.
5.1.2 Power Supply Considerations
The on-board LDO regulator which supplies +3.3 V has a built-in current limit of 2.0 A. Make sure the total
current required by the RA MCU, any active on-board features, and any connected peripheral devices does
not exceed this limit.
Note: The total current available from a typical USB host is 500 mA maximum. Depending on the
configuration of the kit, multiple power sources may be required.
5.1.3 Power-up Behavior
When powered, the white LED near the center of the board (the “dash” in the EK-RA2E1 name) will light up.
For more details on initial power up behavior, see the EK-RA2E1 Quick Start Guide.

5.2.1 Debug On-Board
The on-board debug functionality is provided using Renesas S124 Debug MCU and SEGGER J-Link®
firmware. Debug USB Micro-B connector (J10) connects the S124 Debug MCU to an external USB Full
Speed Host, allowing re-programming and debugging of the target RA MCU firmware. This connection is the
default debug mode for the EK-RA2E1 board.
The S124 Debug MCU connects to the target RA MCU using the SWD interface.
Table 4. Debug USB Connector
A yellow indicator, LED5, shows the visual status of the debug interface. When the EK-RA2E1 board is
powered on, and LED5 is blinking, it indicates that the S124 Debug MCU is not connected to a programming
host. When LED5 is on solid, it indicates that the S124 Debug MCU is connected to a programming
interface.

Pressing the Reset switch (S3) generates a reset signal to restart the RA MCU.
Table 18. EK-RA2E1 Board Switches
The User Switches S1 and S2 may be isolated from the Main MCU, so the associated ports can be used for
other purposes. To separate S1 from P004, Trace Cut Jumper E31 must be open. To separate S2 from
P015, Trace Cut Jumper E32 must be open.

5.4.3 MCU Boot Mode
A two-pin header (J16) is provided to select the Boot mode (P201) of the RA MCU. For normal operation, or
Single-Chip mode, leave J16 open. To enter SCI Boot mode place a jumper on J16.

6. MCU Native Pin Access Area
Figure 20. Native Pin Access Area
6.1 Breakout Pin Headers
The EK-RA2E1 board pin headers, J1, J2, and J3, provide access to all RA MCU interface signals, and to
voltages for all RA MCU power ports. Each header pin is labeled with the voltage or port connected to that
pin. Refer to the RA2E1 MCU Group User’s Manual for details of each port function, and the EK-RA2E1
board schematic for pin header port assignments.
The placement of the breakout pin headers allows for a standard 2.54 mm (0.100”) center breadboard to be
placed on all four pin headers simultaneously. This can be used for prototyping and testing of custom
circuitry for use with the RA2E1 MCU.
6.2 MCU Current Measurement
Included in the Native Pin Access area is a current measurement resistor and test points to measure the
MCU core power current.
The EK-RA2E1 board provides a precision 5 mΩ resistor (Vishay, part number W SL P08 055 L00 0FE A18) for
current measurement of the main 3.3 V MCU power. Measure the voltage drop across these resistors and
use Ohm’s Law to calculate the current. For convenience, TP1 and TP3 are provided to measure the main
3.3 V MCU power. See Figure 22 for the location of TP1 and TP3.
