USB-C100, USB-C101 Turn-Key Modules

The USB-C100 & USB-C101 USB “Type-C” Turn-key Modules – Complete Digital Audio Solutions Embedded inside a USB-C Connector

While nearly identical to the TDTSI010 USB-C (USB “Type-C”) dongle and TDTSI016 from a functional standpoint (sans GPIO-based buttons, integrated microphone, board size and cables), the USB-C100 / USB-C101 is Tempo’s USB-C Headphone / HeadsetFemale 3.5mm Adapter embedded connector complete turn-key module offering. It features the brand new CP2616 – USB to I2S Digital Audio Bridge Controller from SiLabs. This highly cost-effective solution is targeted at Android™ / Windows® / macOS® X / Linux® OS-powered mobile / desktop / laptop / tablet devices.

Unlike the TDTSI0101 and TDTSI016 turn-key reference designs which connects the CP2615 via discrete GPIO signals to discrete push-buttons (removing the need for an additional PCB or PCB space), the USB-C100 / USB-C101 turn-key modules enable ANY OEM or ODM to simply convert their current Android 3.5 mm Headset Specification-compliant product that employs a single push button (Function A) or 3 push buttons (Functions A, B & C) which are designed using the simple resistor-ladder network per the Android 3.5mm: Headset Accessory Specification.

The RoHS compliant USB-C100 / USB-C101 modules are the simplest and fastest time to market solution for OEMs or ODMs desiring to make a Headset product that is 100% Compliant to the Android USB Headset: Accessory Specification


The conversion process to USB Type-C from your current 3.5mm Headset  is as simple as
1, 2, 3…

1.) Solder the 4 wires from a 3.5mm headset to the 4 pads on the end of the USB-C100 / C101 turn-key module, which follows the CTIA standard, from top pad to bottom pad as shown on page 2 of the USB-C100 / USB-C101 Product Brief v0.6 document.

2.) Wrap USB-C100 / USB-C101 module and end of Headset wire connection in plastic / polymer / rubber / etc.

3.) Test, package, & ship your new USB-C Headset.

It just doesn’t get any easier.

No firmware to develop.

No software to develop.

No app to develop.

Nothing to debug.
