5.10.6.9.2 HDQ/1-Wire—1-Wire Mode

Table 5-69 and Table 5-70 assume testing over the recommended operating conditions and electrical characteristic conditions below (see Figure 5-45, Figure 5-46, and Figure 5-47).

Table 5-69 HDQ / 1-Wire Timing Requirements - 1-Wire Mode

NO. PARAMETER DESCRIPTION MIN MAX UNIT
HDQ10 tPDH Presence pulse delay high 15 60 µs
HDQ11 tPDL Presence pulse delay low 60 240 µs
HDQ12 tRDV Read data valid time tLOWR 15 µs
HDQ13 tREL Read data release time 0 45 µs

Table 5-70 HDQ / 1-Wire Switching Characteristics - 1-Wire Mode

NO. PARAMETER DESCRIPTION MIN MAX UNIT
HDQ14 tRSTL Reset time low 480 960 µs
HDQ15 tRSTH Reset time high 480 µs
HDQ16 tSLOT Bit cycle time 60 120 µs
HDQ17 tLOW1 Write bit-one time 1 15 µs
HDQ18 tLOW0 Write bit-zero time(2) 60 120 µs
HDQ19 tREC Recovery time 1 µs
HDQ20 tLOWR Read bit strobe time(1) 1 15 µs
  1. tLOWR (low pulse sent by the master) must be as short as possible to maximize the master sampling window.
  2. tLOW0 must be less than tSLOT.
