TS-4100 Specifications
Power Specification
The TS-4100 module accepts a nominal 5 VDC input.
| Input | Min. Voltage | Max. Voltage |
|---|---|---|
| 5 VDC | 4.7 VDC [1][2] | 5.3 VDC |
- ↑ Some USB peripherals will not function below 5 VDC.
- ↑ The TS-SILO supercapacitors on compatible baseboards are not able to fully charge with less than 5 VDC input.

I/O Specifications
The GPIO external to the TS-4100 are all nominally 3.3 V, but will have differences depending on if they are CPU/FPGA pins.
The CPU pins can be adjusted in software and will have initial values in the device tree. This allows for an adjustment of the drive strength and pull strength of the I/O. See the device tree for information and details about specific I/O.
The FPGA I/O cannot be adjusted further in software.
| IO | Typical Range | Absolute Range | Logic Low Max. Input | Logic High Min. Input | Drive Strength |
|---|---|---|---|---|---|
| External CPU GPIO | 0 V to 3.3 VDC | -0.5 V to 3.6 V | 0.99 V | 2.31 V | 50 mA |
| External FPGA GPIO | 0 V to 3.3 VDC | -0.5 V to 3.75 V | 0.8 V | 2.0 V | 8 mA |
Refer to the MachXO2 Family Datasheet for more detail on the FPGA I/O. Refer to the CPU datasheet for further details on the CPU I/O.
| Note: | Do not drive any I/O externally until the 3.3 V rail is valid. Doing so can violate the power sequencing causing boot failures or damage to the device. |
Power Output
The TS-4100 generates all internally used voltages from the supplied 5 V input. In addition to that, it outputs a 3.3 V source on the TS-SOCKET connector to provide a reference to the attached baseboard or supply power to some baseboard peripherals.
| Rail | Current Source | Location |
|---|---|---|
| 3.3 V | 500 mA | CN2_13, CN2_39 |
