Evaluation Board Mod. R4320CEVB - Evaluation Board allows managing the Lepton x1 and Lepton x4 readers directly using an USB interface (via the embedded USB to UART converter). This board is particularly suited for Lepton x1 and Lepton x4 readers evaluation and SW development purpose. For more information, please refer to §...
3 HARDWARE INTERFACE Introduction An example R3101C Lepton x1/R3104C Lepton x4 system-level block diagram for an embedded system is shown in Fig. 3.1: Lepton3x1 R3101C/Lepton3x4 R3104C - Example of Block Diagram. This figure shows the electrical connections that may and must be made to control the R3101C Lepton x1 / R3104C Lepton x4.
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.
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.
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.
