Part Details for CY8C24423A-24LTXI by Cypress Semiconductor

Many systems require a variety of voltages to power the ASICs, FPGAs, and standard logic found in today's designs. To further complicate the design, some of these devices require voltages to power-on in a specific sequence, lest damage to the chip will occur. There are a variety of voltage monitoring and sequencing devices available today. However, they can be expensive and often do not meet the needs of the design since they offer little or no programmability. A PSoC devices is an excellent choice for monitoring and sequencing the voltages. With its analog structure and programmability, the PSoC can be a perfect fit for the most stringent designs.

The analog blocks of PSoC can be used to process the signal from a PIR (Pyroelectric Infrared) motion sensor and detect the presence of objects that emit infrared light. This Application Note describes an application where PSoC is used to detect the presence of human beings to control an electric load. This circuit can be used for controlling a porch light or operating a door.

This element describes the implementation of a dual-tone multiple frequency (DTMF) detector.

This element describes the implementation of a multi-channel fan speed control system. The proposed implementation shows how to use low-cost, two-wire fans in different temperature control systems.
