2.5 Digital Communication
Most HB LED-based lighting systems require some form of
digital communication to send and receive data to and from the
light fixtures to control them. The CY8CLED16P01 is a
one-device solution for HB LED lighting control and powerline
communication. However, the CY8CLED16P01 supports
several other data communication protocols, apart from
powerline communication. These are listed in
of the hardware is dedicated for a protocol and does not use any
digital blocks. Some protocols use digital blocks to implement the
communication.
A DMX512 protocol receiver can be implemented using two
digital blocks. This is a standard protocol that is common in stage
and concert lighting systems. The receiver has a software
programmable address and programmable number of channels
that it can control. A typical DMX512 receiver implementation
(developed by Cypress) controlling three LED channels
consumes five digital blocks (three for the LED modulators).
Table 2-1. Digital Communication Resource Usage
DALI is another lighting communication protocol that is common
for large commercial buildings. The DALI slave can be imple-
mented in EZ-Color consuming six digital blocks (three for the
DALI slave and three to modulate 3 LED channels). The three
blocks used to implement DALI need not be communication
blocks as the Manchester encoding is performed in the software.

Apart from these specific lighting communication protocols, the
industry standard communication protocols such as I
and SPI can be implemented in any of the devices in the family.
As examples, SPI can be used to interface to external WUSB
devices, while I

2.6 Other Functions
The CY8CLED16P01 is capable of functions other than those
previously discussed. Most functions that can be implemented
with a standard microcontroller can be also implemented with the
CY8CLED16P01.
Similar to regular PSoC devices, the CY8CLED16P01 also has
dynamic reconfiguration ability. This is a technique that enables
the device’s digital and analog resources to be reused for
different functions that may not be available simultaneously. For
instance, consider the application to remotely control LED
color/intensity (with current feedback) over powerlines using the
CY8CLED16P01 for both PLC and LED color control. The PLC
functionality and the current feedback do not necessarily need to
happen at the same time. Therefore, the digital and analog
blocks that implement the PLC functionality can dynamically
reconfigure into resources that implement current feedback. By
doing this, the CY8CLED16P01 device gets more functionality
out of a fixed number of resources than would otherwise be
possible. The only constraint on this technique is the amount of
Flash and SRAM size required for the code to implement these
functions. For more details on dynamic reconfiguration, refer to
application note AN2104, PSoC Dynamic Reconfiguration .
