With its unique array of configurable blocks, PSoC® 3 is a true system level solution providing microcontroller unit (MCU), memory, analog, and digital peripheral functions in a single chip. The CY8C38 family offers a modern method of signal acquisition, signal processing, and control with high accuracy, high bandwidth, and high flexibility. Analog capability spans the range from thermocouples (near DC voltages) to ultrasonic signals.
The CY8C38 family can handle dozens of data acquisition channels and analog inputs on every general-purpose input/output (GPIO) pin. The CY8C38 family is also a high-performance configurable digital system with some part numbers including interfaces such as USB, multimaster inter-integrated circuit (I2C), and controller area network (CAN). In addition to communication interfaces, the CY8C38 family has an easy to configure logic array, flexible routing to all I/O pins, and a high-performance single cycle 8051 microprocessor core. You can easily create system-level designs using a rich library of prebuilt components and boolean primitives using PSoC Creator™, a hierarchical schematic design entry tool. The CY8C38 family provides unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute design changes through simple firmware updates.

CY8CKIT-001 PSoC開發套件(DVK)
The CY8CKIT-001 PSoC® Development Kit (DVK) provides a common development platform where you can prototype and evaluate different solutions using any one of the PSoC 1, PSoC 3, or PSoC 5 architectures.
The PSoC DVK gives you a practical understanding of PSoC technology. In addition, the kit includes several example projects with step-by-step instructions to enable you to easily get started developing PSoC solutions. This kit includes PSoC 1, PSoC 3, and PSoC 5 Family Processor Modules.
The CY8CKIT-001 PSoC Development Board is designed to aid hardware, firmware, and software developers in building their own systems around Cypress’s PSoC devices. The flexibility to configure the power domains is one of the foremost features of this board. Input power to the board is from one of two sources:
■ 12V 1A power supply adapter
■ 9V alkaline battery (not included)
This full featured board incorporates three onboard linear regulators that power peripherals and PSoC processor modules at voltages between 1.7V and 5.0V. These regulators include a fixed 5V 1A linear regulator, a fixed 3.3V 300 mA linear regulator, and a 1.5V to 5.5V 300 mA adjustable regulator. The board also provides the ability to separate the PSoC core VDD rail into two separate rails, analog and digital. In addition, the board is able to separate the I/O VDD rails, giving the flexibility to power the I/O ports at different voltages.
The board is equipped with a 2x16 alphanumeric LCD module capable of 1.8V to 5.0V I/O. In addition, there is a mini-B full speed USB interface and a female DB9 serial communications interface. Also included is a 12-pin wireless radio module interface which can be used to develop CyFi™ Low-Power RF or other embedded RF solutions with this kit. The board also has a prototyping area containing a small breadboard complete with I/O port sockets nearby, multipurpose LEDs, mechanical push buttons, and a multipurpose variable resistor. In addition, three capacitive sensing elements (two buttons and a five segment slider) are included on the board to allow the evaluation of CapSense® applications.
The board has four GPIO expansion slots, allowing the I/O to expand to external boards.
The board was designed with modularity in mind and, as a result, supports removable processor modules. This allows you to plug different PSoC processor modules into the board based upon the desired features of both 8-bit and 32-bit PSoC devices.
