Control System Timing and Data Format

Applications control the LC75342 and LC75342M by applying the stipulated serial data to the CL, DI, and CE pins. This

data consists of a total of 40 bits, of which 8 bits are the address and 32 bits are the data itself.

• Address code (B0 to A3)

The LC75342 and LC75342M have an 8-bit address code, and can be used together with other ICs that support the

Sanyo CCB serial bus format.
