Slave Address
The 7-bit slave address is selected using the ADS pin. When ADS = “L” the address is 48h (1001000b), when
ADS = “H” the address is 49h (1001001b), and when ADS = “Z” (open) the address is 4Ah (1001010b). A
maximum of three SM5320A devices can be connected to the same I
independently by setting the slave address of each using the ADS pin. When writing to control register, send
sub address of control register following slave address.
SLAVE ADDRESS for control register write (1st byte)
SUB ADDRESS for control register write (2nd byte)
Control Register
The SM5320A has a 4-byte control register.
