POWER

Regarding the power supply, the device has just one supply power source:

In the S100 Slave – uSD Holder v1.1 the power source comes from the Rhomb.io module connectors. The source used is VDD. To supply “VDD”, we use “2V8”.

As per the supply lines used on the board, there is a summary on the next table.

Signal (Rhomb.io)	Signal (module)	Voltage (V)	Used
1V8 150mA	1V8	1.8	No
2V8 150mA	2V8	2.8	YES
3V3	3V3	3.3	No
5V_USB	USB/OTG	5	No

BLOCK DIAGRAM

The next figure shows the Block Diagram for the S100 Slave – uSD Holder v1.1.

ID Memory

The DS28E05 is a 112-byte user-programmable EEPROM organized as 7 pages of 16 bytes each. Memory pages can be individually set to write protected or EPROM emulation mode through protection byte settings. Each part has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip.

Applications:

• Accessory/PCB Identification
• Medical Sensor Calibration Data Storage
• Analog Sensor Calibration
• Aftermarket Management of consumables

Features:

• Single-contact 1-Wire Interface
• 112 Bytes User EEPROM with 1k Write Cycles
• Programmable Write Protection and OTP EPROM Emulation Modes for User Memory
• Unique Factory-Programmed 64-Bit ROM ID Number
• Operating Range: 1.71V to 3.63V, -40ºC to +85ºC

The configuration is shown in the next image:

Warranty

• Precaution against Electrostatic Discharge. When handling Rhomb.io products, ensure that the environment is protected against static electricity. Follow the next recommendations:

1. The users should wear anti-static clothing and use earth band when manipulating the device.
2. All objects that come in direct contact with devices should be made of materials that do not produce static electricity that would cause damage.
3. Equipment and work table must be earthed.
4. 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.

• EMS (Electromagnetic Susceptibility). Note that semiconductor devices characteristics may be affected by strong electromagnetic waves or magnetic field during operation.
