Finally, as opposed to last week’s “hack,” each bus is bidirectional, which means the PCA9547 is fully compliant with the I²C spec. Selecting one of the eight I²C buses is done via a ...

However, there is lot to be said for using bus switches in I2C, when they are not strictly needed. Just because you can multidrop a whole system on one bus pair, doesn’t mean that you should do it.

Figure 44 in section 7.24 of the UM10204 I2C-bus specification and user manual presents a method of amelioration (Figure 1). Advertisement. Figure 1: Switched-pullup circuit where the analog switch is ...

The I2C reference design has a 7-bit address space that can be expanded with an infrequently used 10-bit extension. The most common I2C bus speeds are the 100-kb/s standard mode and the 400-kb/s ...

San Jose, Calif. – Targeting industrial applications and high-end systems that can benefit from an I2C serial bus but are not equipped for one, Philips Semiconductors has launched a parallel-to-serial ...

Bytom -- April 2, 2013-- Digital Core Design, an IP Core and System on Chip design house from Poland, has introduced its newest I2C Bus Interface soft core.It is fully compatible with Philips v. 3.0 ...

NXP Semiconductors has introduced its first no-offset I2C-bus buffers, which are designed to isolate capacitance and so allow interface with other bus buffers. Significantly, the bus buffers use the ...

One reason for this triggered sequence approach is that the 1-wire bus main interface has no hope of keeping up with the raw data rate of its slave interface – the 1-wire interface works at 11kbit/s ( ...

The Inter-Integrated Circuit (often referred to as I2C, I2C, or IIC) bus's origins date back to the late 1970s and early 1980s during the rapid rise of what would eventually be referred to as ...
