This figure shows the electrical connections that may and must be made to control the R3101C Lepton x1 / R3104C Lepton x4.
  • Page 12: Power Supply

    Fig. 3.2: BSL Sequence The BSL program execution starts when TST pin has received a minimum of two positive transitions and if TST is high while /RST rises from low to high. BSL_SEL shall be at high level before BSL starts. Pulses length and distance between edges of all signals shall be 10ms at least.
  • Page 13: Reset Pin

    Reset Pin The R3101C Lepton x1/R3104C Lepton x4 may be reset by a logic low voltage on the NRST pin (pin 14). Usage of this pin is recommended in all designs. It may be used to reset the part if an unexpected operating state is entered.
  • Page 14: Wakeup Pin

    Wakeup Pin The WKUP pin is used to wake the device when it is in the Standby or Sleep operating modes. This pin is edge sensitive and will wake the device on a rising edge. The WKUP pin must be logic low in order for the device to re-enter Idle mode after a Sleep wakeup, so it should only be pulsed high to wake up the part.
