8 / 26 page  8 AC Electrical Specifications Electrical Characteristics over recommended operating conditions. Typical values at 25 °C, VDD3=2.6V. Parameter Symbol Minimum Typical Maximum Units Notes Motion delay after reset tMOT-RST 23 ms From SW_RESET register write to valid motion, assuming motion is present Shutdown tSTDWN 50 ms From STDWN pin active to low current Wake from shutdown tWAKEUP 1s From STDWN pin inactive to valid motion. Notes: A RESET must be asserted after a shutdown. Refer to section "Notes on Shutdown and Forced Rest", also note tMOT-RST Forced Rest enable tREST-EN 1s From RESTEN bits set to low current Wake from Forced Rest tREST-DIS 1s From RESTEN bits cleared to valid motion MISO rise time tr-MISO 150 300 ns CL = 100pF MISO fall time tf-MISO 150 300 ns CL = 100pF MISO delay after SCLK tDLY-MISO 120 ns From SCLK falling edge to MISO data valid, no load conditions MISO hold time tHOLD-MISO 0.5 1/fSCLK µs Data held until next falling SCLK edge MOSI hold time tHOLD-MOSI 200 ns Amount of time data is valid after SCLK rising edge MOSI setup time tSETUP-MOSI 120 ns From data valid to SCLK rising edge SPI time between write commands tSWW 30 µs From rising SCLK for last bit of the first data byte, to rising SCLK for last bit of the second data byte. SPI time between write and read commands tSWR 20 µs From rising SCLK for last bit of the first data byte, to rising SCLK for last bit of the second address byte. SPI time between read and subsequent commands tSRW tSRR 500 ns From rising SCLK for last bit of the first data byte, to falling SCLK for the first bit of the address byte of the next command. SPI read address-data delay tSRAD 4 µs From rising SCLK for last bit of the address byte, to falling SCLK for first bit of data being read. NCS inactive after motion burst tBEXIT 500 ns Minimum NCS inactive time after motion burst before next SPI usage NCS to SCLK active tNCS-SCLK 120 ns From NCS falling edge to first SCLK rising edge SCLK to NCS inactive (for read operation) tSCLK-NCS 120 ns From last SCLK rising edge to NCS rising edge, for valid MISO data transfer SCLK to NCS inactive (for write operation) tSCLK-NCS 20 us From last SCLK rising edge to NCS rising edge, for valid MOSI data transfer NCS to MISO high-Z tNCS-MISO 500 ns From NCS rising edge to MISO high-Z state MOTION rise time tr-MOTION 150 300 ns CL = 100pF MOTION fall time t F -MOTION 150 300 ns CL = 100pF SHTDWN pulse width tP-STDWN 1s Transient Supply Current IDDT 45 mA Max supply current during a VDD ramp from 0 to 2.6V |
