The S100 Stacked Voltage Translator v1.0 Module is a Rhomb.io platform compatible module created to modify and condition the signals of other modules. It works as the interface between two modules which have two different voltage levels. The connection between the signals' supplier and the signals' receiver is done by the Rhomb.io standard connectors(two receptacle and two plug connectors of fifty pins each one). It includes four Voltage Translators (FXMA108), which are used to reconfigure some signals voltage.

The "S100 Stacked Voltage Translator v1.0 Module" is a module that allows the connection between modules that were not able to be connected. When the voltage of the signals is high or low and needs to be conditioned, the "S100 Stacked Voltage Translator v1.0 Module" can be used to modify it between a range that depends on the FXMA108. In the "S100 Stacked Voltage Translator v1.0 Module", the voltage range is as high as 5,5V to as low as 1,65V. It is important to mention that the FXMA108 used in the "S100 Stacked Voltage Translator v1.0 Module" are bi-directional, so this module can be even used if it is needed to modify the A port tracks level or the B port tracks level.
Regarding the power supply, two main sources are used: VCCB and VIO_IN. To supply "VCCB" we can use "3V3", "2V8", "1V8" or "VSYS". All of these power supplies, come from the Rhomb.io module connectors as it is shown in the Block Diagram. There is a solder jumper for each power supply. All of them are connected by one side to each power supply and by the other side to "VCCB". You can choose "VCCB" by soldering one of the solder jumpers. By default "VCCB" is not connected to any power source. "VIO_IN" is a power source that comes from the Rhomb.io module connectors. The power sources' configuration should be carried out on the Rhomb.io core. Here it is the Block Diagram of the S100 Stacked Voltage Translator v1.0 Module :
These are the serial communication ports reconfigured on the module: UART, SPI, I2C, QSPI, CAN, CAPT, INT and PWM. Before being connected to the Top Rhomb.io Connectors, all of them go through the voltage translators(FXM108). We can choose the output voltage depending on "VCCB". There are other ports : SDIO-A, SDIO-B, CLK32K, #NMI, RESET, AD, DIFF and USB, which are connected directly between the Top and Bottom Connectors.
There are four connectors used in this module: "J101-BOT", "J102-BOT", "J101-TOP" and "J102-TOP". All of them are Connectors of fifty pins each one. "J101-BOT" and "J102-TOP" are plug connectors, and "J102-BOT", "J101-TOP" are receptacles. To make this module be an interface between others the connectors are placed in a specific way, as we can see in the image below.
The next figure identifies the main parts of the S100 Stacked Voltage Translator v1.0 Module. It can be found specific information for some of those parts on the following sections.
The FXMA108 is a configurable dual-voltage supply translator designed for both unidirectional and bi-directional voltage translation between two logic levels. The device allows translation between voltages as high as 5.5V to as low as 1.65V. The A port tracks the VCCA level and the B port tracks the VCCB level.
- Bi-directional Interface
- Fully Configurable: Inputs and Outputs Track VCC
- Non-Preferential Power-Up; Either VCC may be Powered-Up first
- Outputs Remain in 3-State Until Active VCC Level is Reached
- Outputs Switch to 3-state if Either VCC is at GND
- 80 Mbps Throughput when translatin between 2.5V and 5.0V
- Cell Phones
- Digital Camera
- Portable GPS
In the "S100 Stacked Voltage Translator v1.0 Module" there are four voltage translators to reconfigurate some of the signals used in the module: UART, SPI, I2C, QSPI, CAN, CAPT, INT and PWM.
Each FXMA108 has 20 pins, which configuration is shown in the next table:
-VOLTAGE TRANSLATOR 1 (U1)
-VOLTAGE TRANSLATOR 2 (U2)
-VOLTAGE TRANSLATOR 3 (U3)
-VOLTAGE TRANSLATOR 4 (U4)
NOTE: It is important to mention, that the signals configured as outputs (OUT) in the table, are the signals that come from the Top Rhomb.io Connectors to the Voltage Translators. The signals configured as inputs (IN) in the table, are the signals that come from the Bottom Rhomb.io connectors to the Voltage Translators. The FXMA108 are Bi-directional so the Output signals could work as well as inputs, and the inputs as well as outputs.
There are four solder jumpers in the "S100 Stacked Voltage Translator v1.0 Module". They are used to connect the different power supplies: "3V3", "2V8", "1V8" or "VSYS" to "VCCB". Any of them is soldered. "VCCB" can be chosen by soldering one of them, as it was mentioned in "Module specification";"Key features".

Bill of materials
- Precaution against Electrostatic Discharge. When handling Rhomb.io products, ensure that the environment is protected against static electricity. Follow the next recommendations:
- The users should wear anti-static clothing and use earth band when manipulating the device.
- All objects that come in direct contact with devices should be made of materials that do not produce static electricity that would cause damage.
- Equipment and work table must be earthed.
- Ionizer is recommended to remove electron charge.
- Contamination. Be sure to use semiconductor products in the environment that may not be exposed to dust or dirt adhesion.
- Temperature/Humidity. Semiconductor devices are sensitive to environment temperature and humidity. High temperature or humidity may deteriorate semiconductor devices characteristics. Therefore avoid storage or usage in such conditions.
- Mechanical Shock. Care should be exercised not to apply excessive mechanical shock or force on the connectors and semiconductors devices.
- Chemical. Do not expose semiconductor device to chemical because reaction to chemical may cause deterioration of device characteristics.
- Light Protection. In case of non-EMC (Epoxy Molding Compound) package, do not expose semiconductor IC to strong light. It may cause devices malfunction. Some special products which utilize the light or have security function are excepted from this specification.
- Radioactive, Cosmic and X-ray. Semiconductor devices can be influenced by radioactive, cosmic ray or X-ray. Radioactive, cosmic and X-ray may cause soft error during device operation. Therefore semiconductor devices must be shielded under environment that may be exposed to radioactive, cosmic ray or X-ray.
