3.1 Jumpers and DIP Switch settings

3.1.1 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

esistor shorts the pads together.

The silk screen overlay printing ar ound 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 co nsidered 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.)

4.2 Power Requirements

TB-S3A6 is designed for 3.3 Volt operation. Note that this also means that 5V PMOD devices cannot be used together with the TB-S3A6 unless they are powered separately.

The total current available from the LDO regulator for all connected circuits is 0.600A or less, depending the 5V power source used.

4.2.1 Power supply options

TB-S3A6 can be powered via several different methods:

Option 1: Debug USB (Default)

The default power source is 5V 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 5V signal to 3.3V, which then is used to power the MCU and any connected devices.

The 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. The Copper Jumper E35 is closed for this configuration.

Option 2: Test Points TP3 and TP4

The TB-S3A6 can also be powered by installing a 5V power source a cross TP3 (positive input) and TP4 (negative input). The Copper Jumper E35 must be opened to enable powering the board using these test points.

The on-board Low Dropout Regulator (see Section 4.3: Major Components) has an input voltage range of +3.3V to +5.5V, and a built-in current limit of 600 mA. Make sure any external power source connected to TP3 and TP4 meets these requirements.

R12UM0014EU0100 Rev.1.00 Page 10 of 43 Aug 23, 2017

Page 11

Target Board S3A6 (TB-S3A6) User's Manual

Option 3: Test Points TP1 and TP2

The TB-S3A6 can also be powered by installing a 3.3V source across TP1 (positive input) and TP2 (negative input). Copper jumper E35 must be open to enable powering the board using these test points.

Figure 4 TP1, TP2 and LED1 on Target Board

These test points supply voltage directly to the S3A6 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.

Option 4: Pin Headers

The TB-S3A6 can also be powered through the following pin-headers on the board.

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

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

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

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

The pin headers supply voltage directly to the S3A6 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 4.5 for more information on the Pin Headers.

4.2.2 Power-up behavior

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 On-Board debug interface on the board. If both LEDs in the LED2 package are lit, LED2 appears orange.

Figure 7 LED2 on Target Board (top)

4.2.3 Battery supply configuration

An external battery may be connected according to the methods outlined in Section 4.2.1: Power supply options, providing it meets the minimum voltage and current requiremen ts.

Additionally, an external battery source may be connected to VBAT at Pin Header location J2-29 (J2-12 ground return) to maintain the MCU Real Time Cloc k (RTC) when other main power sources are disconnected from the TB-S3A6.

Page 13

Target Board S3A6 (TB-S3A6) User's Manual

4.2.4 Measuring Current Consumption

Pad 1 and 3 of the Copper jumper E6, which is a dual trace-cut jumper, allow measurement of +3V3 MCU sup ply current. Pad 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.

Note that the actual current consumed by the S3A6 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. Please refer to the S3A6 User’s Manual for more information on the electrical characteristics of the MCU.

Target Board S3A6 (TB-S3A6) User's Manual

Figure 10 E6 on Target 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 connec tion. When not measur i ng 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.

The DEBUG USB Micro-B connection jack connects the S124 J-Link MCU to an external USB Host, FS capable, allowing re-programming and debugging of the Main MCU firmware. Power for the Target Board may be received from this connector.

The J-Link OB interface is multiplexed with the JTAG interface, and can collectively be referred to as the Programming Interface. While the J-Link OB interface and the JTAG interface do not conflict, the J-Link OB signals may be isolated from the programming interface by changing the associated copper jumpers.

J-Link Disconnect Copper Jumpers E32, E33, E34, E37, and E38 connect the J-Link signals to the MCU programming interface. To isolate the J-Link signals from the JTAG interface, the copper jumpers must be open. To allow use of the J-Link interface, each copper jumper must be closed.

J-Link MCU Power Copper Jumper, E1, connects the main +3.3V power to the J-Link +3.3V power. The default condition for E1 is closed, which connects the J-Link MCU power to the main +3.3V power. If J-Link signa ls are disconnected, the power to the J-Link MCU should also be removed by changing E1 to open.

4.5 Target Board Pin Headers

The Target Board pin headers, J1, J2, J3, and J4, provide access to all Main MCU interface signals, and to voltages for all Main MCU power ports.

Fixed Function Pin Assignments

For consistency across all Synergy Target Board Kits, some pin assignments on the headers have fixed function signal assignments. This provides specific signals and functions to be at a common pin header location on all Target Boards for S1, S3, S5, S7 Synergy MCU Series.

On the TB -S3A6, 40 pins of the pin headers are set aside for fixed function assignment. These pins are odd-numbered pins of J1 and even-numbered pins of J2.

Pin Header Fixed Function Pins are labeled on the Target Board with dark text on a white background. Pins that are not Fixed Function pins are labeled with white text on a dark background. On the top side of the board is the functional label for the fixed location. On the bottom side of the board is the port infor mation for the same pin.

Figure 19 Fixed Function Pin Label example

There are several pins in the headers that are secondary fixed f unction pins. These secondary fixed function pins share common pin assignments with other Target Boards having Main MCUs with the same functionality. The secondary fixed function pins are also labele d with the top side having a functional label, and bottom side having a port label.

4.6 Additional Features

4.6.1 Analog Reference Voltages

A footprint for installation of capacitors C21 and C23 is provided on the Target Board. These two capacitors provide noise-bypass capability for ports P010/P011 and for ports P012/P013. See Figure 20 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 Target 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 Target Board was designed for Samsung P/N CL10B104KB8NNNC, or similar, noise-bypass capacitors.

4.6.2 On-Board Clock Crystals

The TB-S3A6 includes two precision crystal clock sources. A precision 12.000 MHz crystal is installed at location X1, and a pr e c isio n 3 2.768 kHz crystal is installed at locatio n X2. These crystal clock sources are connected to the Main MCU by default.

The MCU pins for the 12 MHz clock crystal may be connected to P212 and P213. To disconnect the 12 MHz crystal, open copper jumpers E23 and E24, and close copper jumpers E18 and E19.

The MCU pins for the 32.768 kHz clock crystal may be connected to P214 and P215. To disconnect the 32.768 kHz crystal, open copper jumpers E25 and E26, and close copper jumpers E22 and E27.
