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. -
Page 11: Fig. 3.2: Bsl Sequence
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 12 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.
