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 devi ces 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 switchi ng 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.

Evaluation Kit is supplied by emulator through USB cable. The details of power supply components are
shown in Figure 4-2 and Table 4-1. When the Evaluation Kit is connected to another system then that system
should supply power to the Evaluation Kit.
When operating in stand-alone mode, connect a USB cable to USB1 or USB2 and supply the voltage
through VBUS. At that time, do not use J-Link
TM
OB or USB serial function.

4.3 External Power Supply
It is possible to supply voltage to RE01 power terminal by using external power supply. This allows the entire
or individual power domain to operate at any voltage (1.62 – 3.6V). Normally, the emulator supplies voltage
equivalent to 3.3V, which is the voltage value after reduction by the regulator. (excluding device which can
supply 3.3V)
4.3.1 All power pins
Figure 4-3 shows the component layout. Follow the steps below when supplying voltage from external p
supply to all RE01 power pins:
1. Set SW3 and SW5 to EHC.
2. Open J8 jumper pin 1-2 and 2-3.
3. Supply voltage (1.62V-3.6V) from pin 2 of J8 or T6 using an external power supply.

6.6 Emulator connection in EHC mode
When the RE01 is connected to an emulator, the internal debugging circuitry runs which increases the
power consumption of the RE01 . Therefore, when debugging in EHC mode, it is necessary to keep supplying
enough power to run the device.
The following shows how to debug in EHC mode using a voltage source.
Note 1: This procedure assumes that a program to transition to the steady operation period in Chapter 13
EHC of the UM (the RE01 Group User’s Manual: Hardware) has been constructed. Please write the
program to transition to the steady operation in advance.
Note 2: The power supply from the emulator should be disabled.
6.6.1 Connection and Settings
After setting the board to EHC mode, connect the voltage source and the emulator as shown in Figure 6-19.
For setting the EHC mode, refer to Section 5.2 EHC Operation.
Figure 6-19 shows the case where the on-board super capacitor (BT2) is used as the secondary battery. If
an external secondary battery or super capacitor is used (BT1), connect a voltage source to J12 1pin.

6.6.2 Debugging Procedure
Follow the steps below to debug.
1. Supply power from VSC_VCC (T10) to start RE01.
2. In order to transition from the secondary battery charging period to the steady operation period, apply a
voltage higher than the software threshold voltage. (There is no problem if the voltage is applied before
starting RE01.)
3. Operate the IDE to debug.
If the QUICKMODE bit of RE01 is changed from 1 to 0 after the transition to the steady state, the EHC circuit
will be initialized and the power of RE01 will be turned off. If you wish to debug again, please follow the above
procedure again.

8.10 External DC/DC Circuit
Normally, the internal power supply of RE01 uses a built-in regulator (LDO). However, RE01 can enable an
even lower power consumption by supplying power to the internal power supply from an external DC/DC
converter instead of the internal LDO. Figure 8-15 shows an overview of operation when using a built-in
regulator, and Figure 8-16 shows an overview of operation when using an external DC / DC converter.
For external DC / DC, Renesas ISL9123 is mounted on the board and can be evaluated immediately.
