WebbThe I2C spec has been upgraded over the years from 100kHz to 400kHz (fast mode) and nowadays you can go to speeds over 3MHz. What I specifically look for is the fast speed + mode, being 1MHz or above. Some controller may have this, some don't. I was wondering if the F4xx series do support the 'fast speed +' mode of 1MHz? Webb9 juli 2024 · The I2C Slave interface of EFM8LB1 is a 2-wire, bidirectional serial bus that is compatible with the I2C Bus Specification 3.0. It is capable of transferring in high …

I C uses only two bidirectional open-collector or open-drain lines: serial data line (SDA) and serial clock line (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V, although systems with other voltages are permitted. The I C reference design has a 7-bit address space, with a rarely used 10-bit extension. Common I C bus speeds are the 100 kbit/s standard mode and the … WebbThis resulted in few upgrades to the standard-mode I2C specifications: Fast Mode – supports transfer rates up to 400 kbit/s High-speed mode (Hs-mode) – supports …
