194 / 220 page  Bit representation and coding for fast commands ST25DV04K ST25DV16K ST25DV64K 194/220 DocID027603 Rev 4 Figure 87. Logic 1, low data rate, fast commands Note: For fast commands, bit coding using two subcarriers is not supported. A.2 ST25DVxxx to VCD frames Frames are delimited by an SOF and an EOF. They are implemented using code violation. Unused options are reserved for future use. For the low data rate, the same subcarrier frequency or frequencies is/are used. In this case, the number of pulses is multiplied by 4. For the Fast commands using one subcarrier, all pulse numbers and times are divided by 2. A.3 SOF when using one subcarrier A.3.1 High data rate For the Fast commands, the SOF comprises an unmodulated time of 28.32 µs, followed by 12 pulses at 423.75 kHz (fC/32), and a logic 1 that consists of an unmodulated time of 9.44 µs followed by four pulses at 423.75 kHz, as shown in Figure 88. Figure 88. Start of frame, high data rate, one subcarrier, fast commands A.3.2 Low data rate For the Fast commands, the SOF comprises an unmodulated time of 113.28 µs, followed by 48 pulses at 423.75 kHz (fC/32), and a logic 1 that includes an unmodulated time of 37.76 µs followed by 16 pulses at 423.75 kHz, as shown in Figure 89.
