PCA9624
8-bit Fm+ I 2 C-bus 100 mA 40 V LED driver
The last bit of the address byte defines the operation to be performed. When set to logic 1
a read is selected, while a logic 0 selects a write operation.
7.1.2 LED All Call I 2 C-bus address
? Default power-up value (ALLCALLADR register): E0h or 1110 000
? Programmable through I 2 C-bus (volatile programming)
? At power-up, LED All Call I 2 C-bus address is enabled. PCA9624 sends an ACK when
E0h (R/W = 0) or E1h (R/W = 1) is sent by the master.
See Section 7.3.8 “ ALLCALLADR, LED All Call I 2 C-bus address ” for more detail.
Remark: The default LED All Call I 2 C-bus address (E0h or 1110 000) must not be used as
a regular I 2 C-bus slave address since this address is enabled at power-up. All the
PCA9624s on the I 2 C-bus will acknowledge the address if sent by the I 2 C-bus master.
7.1.3 LED Sub Call I 2 C-bus addresses
? 3 different I 2 C-bus addresses can be used
? Default power-up values:
– SUBADR1 register: E2h or 1110 001
– SUBADR2 register: E4h or 1110 010
– SUBADR3 register: E8h or 1110 100
? Programmable through I 2 C-bus (volatile programming)
? At power-up, Sub Call I 2 C-bus addresses are disabled. PCA9624 does not send an
ACK when E2h (R/W = 0) or E3h (R/W = 1), E4h (R/W = 0) or E5h (R/W = 1), or
E8h (R/W = 0) or E9h (R/W = 1) is sent by the master.
See Section 7.3.7 “ SUBADR1 to SUBADR3, I 2 C-bus subaddress 1 to 3 ” for more detail.
Remark: The default LED Sub Call I 2 C-bus addresses may be used as regular I 2 C-bus
slave addresses as long as they are disabled.
7.1.4 Software Reset I 2 C-bus address
The address shown in Figure 5 is used when a reset of the PCA9624 needs to be
performed by the master. The Software Reset address (SWRST Call) must be used with
R/W = logic 0. If R/W = logic 1, the PCA9624 does not acknowledge the SWRST. See
Section 7.6 “ Software reset ” for more detail.

Software Reset address
Remark: The Software Reset I 2 C-bus address is a reserved address and cannot be used
as a regular I 2 C-bus slave address or as an LED All Call or LED Sub Call address.
