"WebbThe primary difference is that I²C operates them as open-drain outputs at all time, so its speed is limited by the resultant slow signal rise time. I3C uses open-drain mode when necessary for compatibility, but switches to push-pull outputs whenever possible, and includes protocol changes to make it possible more often than in I²C.

Hello there, I have noticed that in the newer STM32 chips it is possible to configure the GPIO's in 2 kinds of output … WebbPush/Pull vs. Open Drain In general, there is no need for pull up resistors in a SPI implementation, because the pins use a push-pull configuration, rather than Open Drain. The output pins are capable of actively creating their own logical high and low states, rather than relying on pull up resistors to generate a default state.

Webb19 nov. 2024 · I 2C requires that if a master in a multi-master environment transmits a high, but see's that the line is low (another device is pulling it down), to halt communications because another device is using the bus. Push-pull interfaces do not allow for this type of freedom, which is a benefit of I 2C. ". This is the first para of Section 1.1 Open ... WebbThe power consumption per bit-transfer in all I3C modes is more efficient than I²C, due to the use of push-pull (vs. Open-Drain) and strong Pull-Up ... I3C Targets may also …

Webb6 maj 2024 · DrAzzy May 5, 2016, 9:28pm 2. Push-pull means that the device will drive the pin high or low. Open drain means that the device can only drive the pin low, and you need an external pullup. For driving an external transistor, you probably want push-pull. Open drain is very convenient for interfacing with lower voltage logic, for example, or if ... Webb27 juni 2016 · So I am reading a tutorial about the I2C bus.

Webb9 apr. 2024 · Let's start with discussing an open drain interface: To produce a Logic High in an open drain interface, a pullup resistor to the supply voltage is required. An example for I2C would be an 8k pullup resistor to 3.3V. This produces a Logic High of approximately 3.3V on the bus. A pulldown resistor on the bus results in a voltage divider.
