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

This allows stand-alone operation of the RL78/G1P independently of control by the IDE while the IDE is applying a forcible reset. Figure 5-3 shows the position of the emulator reset header (EJ1) (only through-holes are provided; an actual header component is not mounted).

5. User Circuits R20UT4661EJ0100 Rev.1.00 Page 13 of 27 Dec.16.19 5.12 External Power-Supply Header When operating the RL78/G1P at a desired external input voltage, or when more current is required than the USB is capable of supplying, use the external power-supply header (J4) to supply power. The usable voltage range is from 2.7 V to 3.6 V. When using this header, remove the pattern (SS1) for cutting on the soldered side (see Figure 5-4). In addition, short-circuit the emulator reset header (EJ1) as described in section 5.11, Emulator Reset Header, to place the emulator in the forced reset state. Figure 5-4 shows the position of the external power-supply header (the J4 header component is not mounted). When power other than 3.3 V is being supplied through the external power-supply header, the connection of Arduino Nano shields is not possible.

User Circuits R20UT4661EJ0100 Rev.1.00 Page 14 of 27 Dec.16.19 5.13 Current Measurement Header The current measurement header (J3) is used to measure the current drawn by the evaluation MCU (the J3 header component is not mounted). 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 (SS2). Figure 5-5 shows the positions of the header and pattern for cutting.

6. Handling Precautions R20UT4661EJ0100 Rev.1.00 Page 15 of 27 Dec.16.19 6. Handling Precautions 6.1 Power to be Supplied The maximum current that the power-supply IC (ISL9005AIRNZ-T from Renesas) can supply is 300 mA during operation at 3.3 V. If power is to be supplied to this product via the USB, take care with the regard to the load that the USB-power source is capable of driving. 6.2 Remodeling the Board Any modification of the board (including removing the patterns for cutting) shall be conducted at the user’s own responsibility. 6.3 Limitation on the Number of Connected RL78/G1P Fast Prototyping Boards Connecting the same host PC to multiple RL78/G1P Fast Prototyping Boards is not possible. 6.4 Power-Supply Circuits and Usage Conditions Different power supplies can be selected by remodeling the board. Table 6-1 shows the relationship between power-supply circuits and usage conditions. Table 6-1 Power-Supply Circuits and Usage Conditions Power-Supply circuit Usage Condition Power supplied to the RL78/G1P Use of Arduino Nano shields*1 Use of boards supported by Pmod*1 Use of an emulator and IDE Remodeling the board*2 As shipped (default) 3.3 V Possible Possible Possible Not required External power- supply header 2.7 V to 3.6 V Only possible with 3.3 V Possible Not possible (The emulator circuit is in the reset state.) Required • J4: mounted; SS1: removed • EJ1: mounted; EJ1: short-circuited Notes: 1. Connecting the RL78/G1P Fast Prototyping Board to an Arduino Nano shield or a board supported by Pmod shall be conducted at the user’s own responsibility and should only proceed after confirming the specifications of the power supply and interfaces. 2. Modifications after shipment for remodeling the board are stated in this column.
