WebWe understand I2C SCL clock frequency of Fast Mode is usually 400kHz. However, we guess that if frequency is 360kHz (less than 400kHz), TSC2007 operates normally. Is my … WebI 2 C uses two bi-directional lines, serial data (SDA) and serial clock (SCL). Typical voltages used are +5 V or +3.3 V. The most common I 2 C bus modes are the 400 kbit/s fast mode, the 100 kbit/s standard mode and the 10 kbit/s low-speed mode. A high speed mode of 3.4 Mbit/s is also available.
