I2c high period
WebbThe I2C bus consists of two lines: serial data line (SDA) and serial clock (SCL). Both lines require pull-up resistors. With such advantages as simplicity and low manufacturing cost, I2C is mostly used for communication of low-speed peripheral devices over short distances (within one foot). Webb9 juli 2024 · Answer. The clock of the I2C bus is composed of four regions: Low time. Rise time. High time. Fall time. Because the I2C module uses pins in open-drain mode, the fall time is relatively negligible, since the drivers will be pulling low reasonably quickly. The other three times compose the overall clock speed.

The original communication speed was defined with a maximum of 100 kbit per second and many applications don’t require faster transmissions. For those that do there is a 400 kbit fastmode and – since 1998 – a high speed 3.4 Mbit option available.
Webb19 nov. 2015 · ex. considering engine will supply clock at 50% duty cycle which means 1.25usec low and 1.25usec high. but according to I2c specification minimum clock low time should be 1.3usec at fastmode (400khz) which violates the rule of i2c standard when we operate at 400khz with 50% duty cycle. WebbWhen there is no transmission of data the I 2 C the bus lines idle in a HIGH state; the lines are passively pulled high. Transmission occurs by toggling the lines by pulling LOW and releasing HIGH. Bits are clocked on falling clock edges. The standard data transfer rate is 100kbits/s while the Fast Mode transfer rate is 400kbits/s.

By default, the lines are pulled high by resistors. To communicate, a device pulls lines low and releases them to let them rise back to high. Ones and Zeroes As a digital bus, I2C ultimately transmits 1s and 0s between two circuits.
