On a wafer basis, the tolerance is ± 2% Timing Characteristics VDD = 1.5V, VSS = 0V, fcoil = 134kHz square wave, Ta = 25°C VC1 = 1.0V with positive peak at VDD and negative peak at VDD -1V unless otherwise specified Timings are derived from the field frequency and are specified as a number of RF periods. Parameter Symbol Test Conditions Value Units Read Bit Period Trdb depending on option 64, 32, 16 RF periods Timing Waveforms BIT n BIT n+1 BIT n+2 64, 32 or 16 TOC, depending on option TOC COIL1 Serial Data Out Fig. 4 |
