Block Diagram - HVAC

Design Considerations
Typical HVAC systems consist of a series ASICs or MCUs which control several brushless DC motors, fans, AC compressor, and heating coils. Additionally, semi and fully-automatic HVAC systems will integrate system/user-interface and graphical display as well as temperature and humidity sensing.

PSoC 3 provides a very versatile HVAC solution. Integrated user-interface, motor control, precision analog sensing, and communication make PSoC 3 the ideal platform.

 •  Industry leading CapSense technology to create a sleek user interface
 •  Highly configurable analog and digital resources allow for flexible motor control over a wide range of configurations
 •  Eliminate costly Hall-Effect sensors and reduce mechanical/electrical complexity
 •  Full CAN 2.0A/B to integrate the system with the entire automotive electronic ecosystem
 •  LIN 2.0 to create local networks for other nodes


Application Notes

AN52701 - PSoC® 3 and PSoC 5LP - Getting Started with Controller Area Network (CAN)
This application note introduces the basic concepts of CAN (Controller Area Network) and demonstrates how CAN bus communication is implemented using PSoC® 3 and PSoC 5LP.

AN58304 - PSoC® 3 and PSoC 5LP – Pin Selection for Analog Designs

AN58827 - PSoC® 3 and PSoC 5LP Internal Analog Routing Considerations
AN58827 discusses how internal trace and switch resistance can affect the performance of a design and how these issues can be avoided by understanding a few basic details about the PSoC® 3 and PSoC 5LP internal analog architecture.

AN60580 - SIO Tips and Tricks in PSoC® 3 / PSoC 5LP
The special input/output (SIO) pins provide differential input buffer and a means to regulate the high-level output voltage (VOH). The SIO pins are tolerant to input voltages higher than the I/O supply voltage and can sink up to 25 mA current. This application note explains the following applications of SIO pins: comparator, charge pump, Salen-key filter, level shifter, half wave rectifier, peak detector, and sleep wakeup using SIO comparator.

Development Kits/Boards

CY8CKIT-001 PSoC® Development Kit

CY8CKIT-017 CAN/LIN Expansion Board Kit
The CY8CKIT-017 CAN/LIN Expansion Board Kit (EBK) is an expansion board that is used with the CY8CKIT-001 PSoC® Development Kit (DVK) or the CY8CKIT-030 PSoC 3 Development Kit (DVK). This EBK enables you to evaluate the Controller Area Network (CAN 2.0A/B) and Local Interconnect Network (LIN 2.1/2.0)slave communication capability of PSoC 3 and PSoC 5 devices in conjunction with Cypress's PSoC Creator™ Integrated Development Environment. The hardware of this EBK includes transceiver circuits for 1 CAN and 2 LIN interfaces. This EBK consists of 2 CAN example projects and 1 LIN example project. You can design your own projects with an easy-to-use CAN and LIN slave components in Cypress's PSoC Creator™ software, or by altering code examples provided with this kit.

CY8CKIT-029 PSoC® LCD Segment Drive Expansion Board Kit
The CY8CKIT-029 PSoC® LCD Segment Drive Expansion Board Kit allows you to evaluate PSoC's LCD drive capability using LCD segment component in Cypress's PSoC Creator™.
