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 andmeasurement tools including work benches and floors must be grounded. The operator must also be grounded using a wrist strap. Semiconductor2.

devices must not be touched with bare hands. Similar precautions must be taken for printed circuit boards with mounted semiconductor devices.
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 ofregister 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 resetpin, 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 the3.

level at which resetting is specified.
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

4.

elements. Follow the guideline for input signal during power-off state as described in your product documentation.
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

5.

become possible.
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

6.

produced with an external resonator or by an external oscillator while program execution is in progress, wait until the target clock signal is stable.
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 VIL(Max.) and VIH (Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the7.

input level is fixed, and also in the transition period when the input level passes through the area between VIL (Max.) and VIH (Min.).
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 these8.

addresses as the correct operation of the LSI is not guaranteed.
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 termsof 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 systemevaluation test for the given product.

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 toeach pad, then remove the connecting copper foil either mechanically or with the assistance of heat. Oncethe etched copper trace is removed, the trace-cut jumper is turned into a solder-bridge jumper for any laterchanges.
A solder-bridge jumper is provided with two isolated pads that may be joined together. The silkscreen
overlay printed around a solder-bridge jumper has gaps in the surround. Three methods can be used forjoining:•••

Solder may be applied to both pads to develop a bulge on each and the bulges joined by touching asoldering 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.

CK-RX65N v2 – User's Manual

For any copper jumper, the connection is considered closed if there is an electrical connection between thepads (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.)

3.3.2

Traditional Pin Header Jumpers

3.3.3

Default Jumper Configuration

These jumpers are traditional small pitch jumpers that require an external shunt to open/close them. The
traditional pin jumpers on the CK-RX65N v2 board are 2.54 mm (0.1”) pitch headers and require compatible
2.54 mm shunt jumpers.
The following table describes the default settings for each jumper on the CK-RX65N v2 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 eachfunctional area of the kit.

Power Supply Options

This section describes the different ways in which CK-RX65N v2 kit can be powered.

Figure 5. Power Supply Options

4.1.1.1 Option 1: Debug USB
5 V may be supplied from an external USB host to the USB Debug connector (J14) labelled USB DEBUG on
the board. Power from this source is connected to the main system 5 V power. Reverse current protection isprovided between this connector and the main system 5 V power.

4.1.1.2 Option 2: USB Full Speed
5 V may be supplied from an external USB host to the USB Full Speed connector (J13) labelled USB FS on
the board. Power from this source is connected to the main system 5 V power. Reverse current protection isprovided between this connector and the main system 5 V power.

5. MCU Native Access Area
5.1

MCU and Pmod Current Measurement

Included in the Native Pin Access area are current measurement resistors and test points to measure the
MCU core power current and Pmod power current.
The CK-RX65N v2 board has pin header test points for current measurement of the main +3.3 V MCU power
and for Pmod power. To measure current, remove 0 Ohm resistor and install pin header. Alternatively use a
resistor of known value and measure the voltage drop across the resistor and use Ohm’s Law to calculate
the current. J2 can be used to measure the MCU power, J1 can be used to measure Pmod 1 power, and J7
can be used to measure Pmod 2 power.
