PCA9665
Fm+ parallel bus to I
2
C-bus controller
10. Application design-in information
10.1 Specific applications
The PCA9665 is a parallel bus to I
2
C-bus controller that is designed to allow ‘smart’
devices to interface with I
2
C-bus or SMBus components, where the ‘smart’ device does
not have an integrated I
2
C-bus port and the designer does not want to ‘bit-bang’ the
I
2
C-bus port. The PCA9665 can also be used to add more I
2
C-bus ports to ‘smart’
devices, provide a higher frequency, lower voltage migration path for the PCF8584 and
convert 8 bits of parallel data to a serial bus to avoid running multiple traces across the
printed-circuit board.
10.2 Add I
2
C-bus port
As shown in
Figure 33
, the PCA9665 converts 8-bits of parallel data into a multiple master
capable I
2
C-bus port for microcontrollers, microprocessors, custom ASICs, DSPs, etc.,
that need to interface with I
2
C-bus or SMBus components.
