General Precautions in the Handling of Microprocessing Unit and Microcontroller
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 external oscillator
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
and V
(Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the input level
IH
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 operation 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.

The first time the CPU board is connected to the USB port of a PC, the monitor of the PC shows the message
stating that installation of the driver is in progress as shown in Figure 5-3. After that, a message indicating
completion of the driver installation is displayed. The content of the message will differ with the OS version on
the host PC.

The ACT LED displays the state of operation of the emulator control software. The illumination conditions are
listed below. The LED is green.
• Illuminated: Indicates that the emulator is connected to the target.
• Blinking: Indicates that the host machine (PC) has recognized the emulator.
• Not illuminated: Indicates that the emulator cannot be used for some reason (including its power being off).
5.6 Power LED
While the power LED is illuminated, power is being supplied to the board. The LED is green.

Table 5-6, and Table 5-7 show the signal specifications of the Arduino UNO connectors (the actual
connector components are not mounted on the board as shipped).

5.11 Current Measurement Header
The current measurement header (J7) is used to measure the current drawn by the evaluation MCU (an actual
header component is not mounted on the board as shipped). The current drawn can be measured by
connecting an ammeter to the evaluation MCU. When this header is to be used, remove the relevant pattern
for cutting (SS20) on the soldered side. Figure 5-8 shows the positions of the header and pattern for cutting.
5.12 MCU Headers
MCU headers are provided for by two sets of through holes (CN3 and CN4) for 28-pin headers (actual header
components are not mounted on the board as shipped). The pin headers have a pitch of 2.54 mm and are
connected to the evaluation MCU. Pin numbers of the MCU headers correspond to those of the evaluation
MCU, and most pins are connected (with pins 1, 3, 4, 19, 22, 28, 32, 37, 38, 39, 40, 44, 45, and 46 as the
exceptions).
5.13 Reset Switch
Pressing the RESET switch applies a hardware reset to the evaluation MCU.
5.14 User Switch
An optional user switch (SW1) is mounted. It is connected to pin 17 of the evaluation MCU, which operates as
pin function P15. The IRQ5 interrupt is multiplexed on the same pin.
5.15 Patterns for Cutting
Patterns must be cut or repaired by soldering if necessary. Figure 5-9 shows examples of the states of
patterns for cutting.

6.1 Modifying the Target Board for RX23W
This section describes how to change the setting of this product by using option-link resistors.
An option-link resistor is a 0-Ω surface-mount resistor, which is used to short-circuit or isolate a part of circuits.
The subsequent sections contain lists of option-link resistors for individual functions. Fit or remove option-link
resistors to switch functions with reference to the list. Resistor numbers in bold blue type indicate the initial
state of the configuration on the Target Board for RX23W as shipped. For the positions of the option links,
refer to chapter 3, Parts Layout.

7. Handling Precautions
7.1 Adding Load
When load is added while power is being supplied via the USB, the maximum current is 300 mA during
operation at 3.3 V.
When load is added while power is being supplied externally, the maximum current is 500 mA regardless of
the operating voltage.
7.2 Remodeling the Board
Any modification of the board (including removing the patterns for cutting) shall be conducted at the user’s
own responsibility.
7.3 Limitation on the Number of Connected Target Boards for RX23W
Connecting the same host PC to multiple Target Boards for RX23W is not possible.
