27 / 68 page ![]() DocID18260 Rev 6 27/68 L99DZ80EP Electrical specifications 67 2.9 SPI / logic – electrical characteristics The voltages are referred to ground and currents are assumed positive, when the current flows into the pin. 6V V S 18 V, 4.75 V VCC 5.5 V; all outputs open; Tj = -40 °C to 150 °C, unless otherwise specified. Table 20. Delay time from Standby to Active mode Symbol Parameter Test condition Min Typ Max Unit tset Delay time Switching time from standby to active mode. Time until output drivers are enabled after CSN going to high and set bit 0 = 1 of control register 0. 250 310 410 µs twakup Wake-up time Switching from standby to active mode. Time after the first falling edge of CSN until the first positive CLK edge, which latches EN = 1 correctly into the device —20 µs tawake Stay awake time Switching from standby to active mode. After the first rising edge of CSN a second SPI frame with EN = 1 is correctly recognized — 256 µs Table 21.
