STM32L476 USB Termination

2014年2月19日 — A full-speed USB device requires a 1.5 kΩ resistor between the USB_DP pin and 3.3 V. A USB host controller has 15 kΩ resistors on both the ...

The USB Line termination is reached through the series resistors, RS1 and RS2 (22 Ω or 30 Ω) connected on the D+ and D− lines. These resistors match the cable ...

2021年10月30日 — The termination resistors (see the section on this below); The connector that will hold your USB cable. You might be wondering, how is it done ...

2023年1月9日 — Another example using 22 ohm termination resistors that is based on a similar STM32 is here. So, should I add 22 ohm series termination ...

I am a little confused about USB termination requirements on the STM32L476 part. I read in the datasheet that termination resistors on D+/D- are not needed and ...

2022年6月28日 — The purpose of Rp and Rd terminations on CC pins is to identify the DFP-to-UFP connection and the CC pin that will be used for communication. To ...

2023年10月26日 — Why do I need to put a 22 Ohm series termination resistor in it? You need to use series resistors on D+/D- lines only if you use a cheap MCU ...

2024年5月31日 — Purpose of Rp, Rd, and Ra types of termination resistors in the USB Type-C connector and what usb c resistor values are used for Rp, Rd, ...

2014年5月9日 — They are series termination resistors. The USB standard specifies that the signal-to-ground impedance is 30 ohms and differential impedance ...
