Note 1: The charging time depends on the environment temperature and the USB specification. Do not use any other batteries
different from Ni-MH battery.
Note 2: The battery voltage may drop to low voltage impossible to charge after this product is not used over a prolonged period.
Uninstall and charge the batteries by dedicated charger.
Note 3: The voltage of battery may drop sharply while the feeding current is large. This is because of the internal impedance of
battery and this depends on specification of battery. Use batteries with large capacity when feeding current is large. Change
batteries when battery performance becomes low because batteries are expendable supplies.
Note 4: The current of charging or feeding depend on the specification of the devices connected. (e.g. USB Battery Charging
Specification corresponding. etc.) This product detects if the device connected is correspond to USB Battery Charging
Specification or not, and controls the charging current according to USB specification.

General Precautions in the Handling of MPU/MCU Products
The following usage notes are applicable to all MPU/MCU products from Renesas. For detailed usage notes on this
products covered by this manual, refer to the relevant sections of the manual. If the descriptions under General
Precautions in the Handling of MPU/MCU Products and in the body of the manual differ from each other, the
description in the body of the manual takes precedence.
1. Handling of Unused Pins
Handle unused pins in accord 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 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. Unused pins should be handled as
described under Handling of Unused Pins in the manual.
2. Processing at Power-on
The state of this product is undefined at the moment 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 moment 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 moment 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 moment when power is supplied until the power reaches the level at
which resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
The reserved addresses are provided for the possible future expansion of functions. Do not access
these addresses; the correct operation of LSI is not guaranteed if they are accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has become stable.
When switching the clock signal during program execution, wait until the target clock signal has
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.
Moreover, 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.
5. Differences between Products
Before changing from one product to another, i.e. to one with a different type number, confirm that the
change will not lead to problems.
The characteristics of MPU/MCU in the same group but having different type numbers may differ
because of the differences in internal memory capacity and layout pattern. When changing to
products of different type numbers, implement a system-evaluation test for each of the products.
