TS-4900 TS-Socket interface
The TS-SOCKET System-on-Modules (SoMs) all use two high density 100 pin connectors for power and all I/O. These follow a common pinout for various external interfaces so new modules can be dropped in to lower power consumption or use a more powerful processor. The male connector is on the baseboard, and the female connector is on the SoM. You can find the datasheet for the baseboard's male connector here. This can be ordered from the TS-Socket SoM product page as CN-TSSOCKET-M-10 for a 10 pack, or CN-TSSOCKET-M-100 for 100 pieces.
In our schematics and our table layout below, we refer to pin 1 from the male connector on the baseboard. For designing a custom carrier board for the TS-4900 we recommend using the TS-8550 as a base: https://www.embeddedTS.com/documentation/ts-8550-schematic.pdf
- ↑ EXT_RESET# is an input used to reboot the CPU. Do not drive active high, use open drain.
- ↑ This is an output which can be manipulated in the #Syscon. This pin can optionally be connected to control a FET to a separate 5V rail for USB to allow software to reset USB devices.
- ↑ 3.0 3.1 3.2 3.3 3.4 3.5 This SD interface is the same one used by the MicroSD on the TS-4900. Only one can be used at a time.
- ↑ OFF_BD_RESET# is an output from the CPU that automatically sends a reset signal when the unit powers up or reboots. It can be connected to any IC on the base board that requires a reset.
- ↑ 5.0 5.1 5.2 5.3 The 5V power pins should each be connected to a 5V source.
- ↑ This is used during production to boot to an offboard SPI flash. This pin should typically be left unconnected.
- ↑ 7.0 7.1 The TS-4900 regulates a 3.3V rail which can source up to 700mA. Designs should target a 300mA max if they intend to use other SoMs.
- ↑ This pin is used as a test point to verify the RAM has a correct voltage for debugging
