Timing specications
The PCD3311C and PCD3312C accept data input from a microcontroller and are ‘slave receivers’ when operating via
the I2C-bus. They support the ‘standard’ and ‘low-speed’ modes of the I2C-bus, but not the ‘fast’ mode detailed in
“The
I2C-bus and how to use it” document order no. 9398 393 40011. The timing requirements for the devices are described
in Sections 8.5.1 and 8.5.2.
8.5.1
STANDARD MODE
Masters generate a bus clock with a maximum frequency of 100 kHz. Detailed timing is shown in Fig.11, where the two
signal levels are LOW = VIL and HIGH = VIH, see Chapter 11. Figure 12 shows a complete data transfer in standard
mode. The time symbols are explained in Table 6.
