General Preca ut ions in the Handling of Microprocessing Unit and Microcontroller Unit Products

The following usage notes are applicab le to all Microprocessing unit and Microcontroller unit products from Renesas.
For detailed usage notes on the products covered by thi s document, refer to the relevant sections of the document as well
as any technical updates that have been issued for the products.

1. 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 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 the produc t is undef in ed 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 a product with a different part number, confirm

that the change will not lead to problems.
 The characteristics of Microprocessing unit or Microcontroller unit products in the same group but

having a different part number may differ in terms of the 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.

WEEE Directive

Renesas development tools and products are directly covered by the European Union's Waste
Electrical and Electronic Equipment, (WEEE), Directive 2002/96/EC.
