Overview
The CY8C21512-12PVXET is an 8-bit microcontroller from the PSoC 1 family, utilizing the M8C core. It features a maximum operating frequency of 12 MHz and includes 16 KB of Flash memory with 1024 bytes of RAM. The device integrates a Delta-Sigma ADC with 10-bit resolution at 5.9 ksps and supports CapSense Plus technology for capacitive touch sensing. It offers 24 GPIO pins, operates within a voltage range of 3 V to 5.25 V, and functions across a temperature range of -40 °C to 125 °C in a 20-pin SSOP package.
Feature Summary
- Integrates CapSense Plus technology for capacitive touch sensing applications
- Includes a Delta-Sigma analog-to-digital converter for signal acquisition
- Provides programmable digital and analog blocks via PSoC Designer software
Applications
- Capacitive touch interface controllers
- Portable consumer electronics
- Battery-powered measurement devices
Procurement Notes
Verify the specific suffix 'T' indicating tape and reel packaging against the required handling method. Confirm the component status as End-of-Life or limited supply through official Infineon channels before finalizing procurement plans. Ensure compatibility with the PSoC Designer development environment for programming and configuration.
Selection Notes
Select this component when a combination of low pin count, integrated capacitive touch sensing, and moderate processing speed is required. The inclusion of a Delta-Sigma ADC makes it suitable for precision sensor interfaces. Evaluate the 20-SSOP package constraints against board space requirements and thermal dissipation needs for the target application environment.
Part Context
This part belongs to the Cypress (now Infineon) PSoC 1 series, designed for highly configurable embedded control. The CY8C215xx variant specifically targets applications requiring mixed-signal capabilities alongside user-interface elements like touch buttons. It represents a solution for reducing external component count by integrating analog and digital peripherals on a single chip.
Replacement Considerations
Check for direct pin-compatible upgrades within the CY8C21xxx series. Verify if newer PSoC generations offer backward-compatible firmware migration paths. Consult official obsolescence notices for recommended alternative part numbers.
