4. Hardware Details

4.1 Jumpers Settings

4.1.1 Copper Jumpers

There are two types of copper jumpers, 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 to each pad then remove the connecting copper foil either mechanically or with the assistance of heat. Once the etched copper trace is removed, the trace-cut jumper is turned into a solder-bridge jumper for any later changes.

A solder-bridge jumper is provided with two isolated pads that may be joined together by one of three methods:

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

The silk screen overlay printing around a solder-bridge jumper is a box with a gap in the lines adjacent to the isolation region between the pads.

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

5.2 Power Requirements

EK-RA4M1 is designed for 3.3 V operation. This also means that 5 V PMOD devices cannot be used together with the EK-RA4M1 unless they are powered separately.

The total current available from the LDO regulator for all connected circuits is 600 mA or less, depending on the 5 V power source used.

5.2.1 Power Supply Options

EK-RA4M1 can be power e d in s ev eral dif f erent ways as described in this section.

R20UT4579EU0101 Rev.1.01 Page 9 of 32 Apr.09.20

Page 13

Renesas RA Microcontrollers EK-RA4M1 v1 – User's Manual

Figure 6. Power Supply Options

5.2.1.1 Option 1: Debug USB (default)

The default power source is 5 V, supplied from an external USB host to the USB Debug connector labelled DEBUG USB on the top surface of the board. A low drop-out regulator (LDO) is used to convert the 5 V signal to 3.3 V, wh ic h then is used to power the MCU and any connected devices.

Copper jumper E35 selects the source for the primary power input to the LDO regulator. By default, this jumper is configured to provide power through the Debug USB connector. Copper jumper E35 is closed for this configuration.

5.2.1.2 Option 2: Test Points TP3 and TP4

The EK-RA4M1 board can also be powered by installing a 5 V power source across TP3 (positive input) and TP4 (negative input). Copper jumper E35 must be opened to enable powering the board using these test points.

The on-board Low Dropout Regulator (see section 5.3, Main Components) has an input voltage range of +3.3 V to +5.5 V, and a built-in current limit of 600 mA. Make sure that any external power source connected to TP3 and TP4 meets these requirements.

Figure 7. USB Debug Connector (J11), TP3, and TP4 on the Evaluation Kit Board

5.2.1.3 Option 3: Test Points TP1 and TP2

The EK-RA4M1 board can also be powered by installing a 3.3 V source across TP1 (positive input) and TP2 (negative input). Copper jumper E35 must be open to enable powering the boar d us ing these tes t poin ts .

Figure 8. TP1, TP2, and LED1 on the Evaluation Kit Board

These test points supply voltage directly to the RA4M1 MCU, the S124 J-Link MCU, and other on-board circuitry. Use caution to ensure that any voltage connected in this manner meets the power requirements for the active features. Power sources that are outside of the published operating range for the active devices may cause degraded performance or damage the board.

R20UT4579EU0101 Rev.1.01 Page 10 of 32 Apr.09.20

Page 14

Renesas RA Microcontrollers EK-RA4M1 v1 – User's Manual

5.2.1.4 Option 4: Pin Headers

EK-RA4M1 board can also be powered through the following pin-headers:

• J1 (pin J1-15 for +3.3 V, pin J1-17 for Return)

• J2 (pin J2-10 for +3.3 V, pin J2-12 for Return)

• J4 (pin J4-37 for +3.3 V, pin J4-36 for Return)

Copper jumper E35 must be open for any of these configurations.

The pin headers supply voltage directly to the RA4M1 MCU, the S124 J-Link MCU, and other on-board circuitry. Use caution to ensure that any voltage connected in this manner meets the power requirements for the active features. Power sources that are outside of the published operating range for the active devices may cause degraded performance or damage the board.

See section 5.5, Pin Headers for more information on the Pin Headers.

5.2.2 Powering up the Board

When powered, the green LED to the right of the DEVICE USB connector (LED2) lights up.

The red LED in the same LED package functions as a status indicator for the J-Link interface on the board. If both LEDs in the LED2 package are lit, LED2 appears orange.

Figure 11. LED2 on the Evaluation Kit Board (Top Side)

5.2.3 Battery Supply Configuration

An external battery may be connected according to the methods outlined in section 5.2.1, Power Supply Options, providing that it meets the minimum voltage and current requirements.

Additionally, an external battery source may be connected to VBAT at Pin Header location J2-29 (J2-12 ground return) to maintain the MCU Realtime Clock (RTC) when other main power sources are disconnected from the EK-RA4M1 board.

5.2.4 Measuring Current Consumption

Pads 1 and 3 of the copper jumper E6, which is a dual trace-cut jumper, allow measurement of +3V3 MCU supply current. Pads 2 and 4 of E6 allow measurement of VBAT supply current. Both traces are connected by default. These traces should be cut to enable power measurement. Care must be taken when cutting the trace to not cause damage to PCB layers below the trace.

On-board (OB) debug

The actual current consumed by the RA4M1 MCU is dependent on many factors, including ambient temperature, internal clock speed, input voltage level, and device activity. The actual current consumed by the MCU can vary from less than 1 mA to nearly 40 mA.

Figure 14. E6 on the Evaluation Kit Board (Bottom side)

Once the shorting traces have been removed, there are several options to measure current:

• Pins can be installed that allow connection of a precision multi-meter or bench meter, or leaded current

shunt to allow oscilloscope or data logger connection. When not measuring the current, this allows easily installed and removed shunts to be used to short the jumper terminals.

• Another option is to install current sense resistors between pads 1 and 3 for +3V3 MCU, and between

pads 2 and 4 for VBAT. Precision non-inductive film or foil resistors are recommended for use in this application, and the value of each resistor should be carefully considered.

For example, if the expected current requirement for the +3V3 MCU supply voltage is 10 mA, and the user would expect to measure a 10 mV drop across the current measurement resistor, then a 1.0-ohm resistor should be selected and installed.

The actual value selected should be based on the operating conditions of the MCU for the specific user application, and the sensitivity of the measurement equipment used.

5.6 Additional Features

5.6.1 Analog Reference Voltages

Footprints for the installation of capacitors C21 and C23 are provided on the board. These two capacitors provide noise-bypass capability for ports P010/P011 and for ports P012/P013. See Figure 24 for the circuit design.

Port pair P010/P011 may be assigned as GPIO, where bypass capacitor C21 would damage signal quality. When P010/P011 are to be assigned as VREFH0/VREFL0, installation of the capacitor C21 can reduce reference voltage noise and improve ADC measurement and DAC output quality. The board was designed for Samsung P/N CL10B104KB8NNNC, or similar, noise-bypass capacitors.

Port pair P012/P013 may be assigned as GPIO, where bypass capacitor C23 would damage signal quality. When P012/P013 are to be assigned as VREFH/VREFL, installation of capacitor C23 may reduce reference voltage noise and improve ADC measurement and DAC output quality. The board was designed for Samsung P/N CL10B104KB8NNNC, or similar noise-bypass capacitors.
