PSoC® 3
|
PSoC® 3 is a true programmable embedded system-on-chip integrating configurable analog and digital peripheral functions, memory and a microcontroller on a single chip. And now our breakthrough new PSoC 3 architecture boosts performance through:
PSoC 3 is now available in Chip Scale Packages (CSP) allowing you to design with the flexibility of PSoC in space constrained and small form factor applications like wearables, fitness products, and mobile devices.

Technology
The PSoC® architecture consists of configurable analog and digital blocks, a CPU subsystem and programmable routing and interconnect. PSoC lets you plug in predefined and tested IP from the PSoC library of functions, or code your own. Either way, you have the flexibility to build innovation and competitive advantage into your products.

CPU Subsystem • Internal main and low-speed oscillator PSoC devices also have dedicated communication interfaces like I2C, Full-Speed USB 2.0, CAN 2.0, and on-chip debugging capabilities using JTAG and Serial Wire Debug. The newest members of the PSoC family offer industry-standard processors like the 8051 and Arm Cortex-M3. |

Device Documentation| Family Datasheet
The PSoC 3 architecture has multiple device families (i.e. CY8C38 family). Each family has a unique datasheet. They are categorized under Datasheets section on cypress website.
The silicon datasheet covers key features of the device, brief operational details, pinout, electrical specifications and characterization graphs. It only focuses on the silicon features. Due to programmable nature of PSoC, new analog and digital peripheral are created continuously. These peripherals are documented in the component datasheets. Some of the very common MCU peripherals like UART or SPI aren't documented in the device datasheet as they are constructed in programmable blocks, they are documented in the component datasheet.

| Family Programming Specifications
This document (available as an application note) provides information on hardware connections for programming, programming vectors required to develop your own PSoC 3 Programmers.
Both Serial Wire Debug (SWD) and Joint Test Action Group (JTAG) interfaces are supported for programming the PSoC 3 device. The programming specifications for all PSoC 3 families are available as application note AN62391.

| Technical Reference Manual
The PSoC 3 Technical Reference Manual provides detailed information on the device features and how they work. It is intended for advance user's who want to understand what's going on under the hood.
In case of MCU, technical reference manual is the most commonly used document for programming. However, in case of PSoC component datasheets provides the same functionality. The technical reference manual is intended to be technical reference to clarify device behavior. It will be mostly used by the advanced users. It isn't intended for the beginners. PSoC 3 has way more registers compared to typical MCU due to highly programmable and flexible system on chip architecture. Therefore, the technical reference manual is split into two documents.

Software DocumentationPSoC Creator Documentation
|
| PSoC Creator Component Datasheet The component datasheet covers component features, its usage and operation details, API description and electrical specifications.
This is the primary documentation used during development. Traditional MCU peripherals and many high level functions are available as component in PSoC Creator. These components can represent fixed function peripherals on the device (i.e. USB, CAN), hardware peripherals constructed with programmable logic (i.e SPI, UART) or high level system function (i.e thermistor). In case of traditional MCU peripherals are accessed through register interface and user is responsible for creating driver layer. In case of PSoC 3, PSoC Creator also creates this driver layer by providing APIs to configure/ control peripheral activity.
The component datasheets are accessible directly from PSoC Creator by right clicking on the component. These component datasheets are also available on Cypress website. |
