CY8C21x23 | Cypress Semiconductor


The PSoC® family consists of many Mixed Signal Array with On-Chip Controller devices. These devices are designed to replace multiple traditional MCU-based system components with a low cost single-chip programmable component. A PSoC device includes configurable blocks of analog and digital logic, and programmable interconnect. This architecture allows the user to create customized peripheral configurations, to match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts.

The PSoC architecture, consists of four main areas: the Core, the System Resources, the Digital System, and the Analog System. Configurable global bus resources allow the combining of all device resources into a complete custom system. Each CY8C21x23 device includes four digital blocks. Depending on the PSoC package, up to two analog comparators and up to 16 general purpose IO (GPIO) are also included. The GPIO provide access to the global digital and analog interconnects.

User Module Datasheets
  • The silicon datasheet covers key features of the device, brief operational details, pin out, electrical specifications and characterization graphs. It only focuses on the silicon features. Analog  functions (for e.g. ADC, DAC) and Digital  functions (for e.g. PWM, timer) are documented in the .
  • The family errata documents operation deviation of device compared to the family datasheet. If certain feature doesn't work as expected it is documented in the errata document. It is very critical that user refers to corresponding errata document as it will document critical issues and workarounds for the device.
Programming Specifications
  • The PSoC® 1 In-System Serial Programming Specification provides programming timing and vectors so that developers and programmer vendors can create their own in-system programming solutions for a PSoC 1 device. The specifications are provided in 3 Application Notes (AN2026A/B/C) with 2 additional Application Notes (AN44168, AN59389) providing working easy to follow example code.
PSoC 1 Programmers
  • The General PSoC Programming web page is central location that details all aspects of programming related to all available PSoC devices like Software, Engineering Programmers, Programming Specifications and Production Programming Vendors.
Technical Reference Manual
  • The PSoC 1 Technical Reference Manual provides detailed information on the device features and how they work. It is intended for advanced user's who want to understand what's going on under the hood.

CY3210 - CY8C21x23 PSoC® Evaluation Pod (EvalPod)

CY3210 - CY8C21x23 PSoC EvalPod connects to the ICE In-Circuit Emulator (CY3215-DK kit) to allow debugging capability. It can also function as a standalone device without debugging capability. The EvalPod has a 28-pin DIP footprint on the bottom for easy connection to development kits or other hardware. The top of the EvalPod has prototyping headers for easy connection to the devices pins.

CY2315-DK IN-Circuit Emulation Development Kit

PSoC 1 devices require an In-Circuit Emulator (ICE) to perform debugging using the CY3215-DK In-circuit Emulation Development Kit. Cypress Semiconductor provides multiple POD foot options (PDIP, QFN, SSOP, SOIC). The POD kits are listed under the CY3210- XXXX or CY3250 – XXXX naming conventions. Visit the or click on the Title above to know more.
Featured Kit: The CY2315 DK software interface allows the user to run, halt, and single step the processor code. It also allows the user to set complex event points. Event points can start and stop the trace memory on the ICE, as well as break the program execution.
In addition to the CY3213 DK, different Emulation Pods are available to support the range of devices in the PSoC 1 family. They plug into (or are soldered onto) the user's circuit board to provide the physical interface. Pods are available for low-cost expansion of the ICE-Cube capability.
