Components of the USB stack are provided for USB hosts and for connected devices. The project code is written in C and is distributed under the MIT license.    <\/p>\n<p>To enhance security, TinyUSB does not use dynamic memory allocation. It supports use in multithreaded applications. For safe multithreaded operation, all events related to interrupt occurrences are not processed immediately upon receiving an ISR (Interrupt Service Request), but are queued and processed in the context of application execution, rather than in the interrupt handler. Semaphores and mutexes are employed when accessing shared resources, such as the FIFO CDC (Communication Device Class).     <\/p>\n<p>The stack is abstracted from the operating system and can be used as a standalone component, independent of the functionality of operating systems. Modules are available for integrating TinyUSB with FreeRTOS, RT-Thread, and Apache Mynewt. Energy-saving features are supported, such as transitioning to sleep mode and waking up upon activity. There is a preliminary implementation of the PD 3.0 (Power Delivery) protocol for managing power transfer over USB Type-C.       <center><img decoding=\"async\" alt=\"The open USB stack TinyUSB 0.19 has been released.\" src=\"\/wp-content\/uploads\/2025\/10\/77b99418cff48336d22a2162c453e404.png\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<p>TinyUSB allows adding support for custom USB device and host classes without modifying the USB stack.
