Overview
The CY8C21234-24SXI is an 8-bit microcontroller from Infineon's PSoC family, featuring the M8C core and housed in a 16-pin SOIC package. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 2.4 V to 5.25 V. The device includes 8 kB of Flash program memory and 512 bytes of SRAM. Key peripherals include a 10-bit ADC with 28 channels, two analog comparators, an 8-bit DAC, and two timers/counters. It supports I2C, SPI, and UART interfaces and offers CapSense functionality for touch sensing applications.
Feature Summary
- Integrates configurable digital and analog peripherals within a single system-on-chip architecture
- Supports CapSense technology for capacitive touch sensing interface implementation
- Provides flexible mixed-signal processing capabilities through programmable logic blocks
Applications
- Capacitive touch sensing user interfaces
- Low-power embedded control systems
- Mixed-signal data acquisition modules
Procurement Notes
Verify the exact part number against official Infineon documentation, as the input model contains a potential typographical error regarding the digit sequence. Confirm package type and suffix codes match your design requirements. Ensure compliance with RoHS standards and check for moisture sensitivity levels prior to assembly. Cross-reference datasheets for specific electrical characteristics and operating temperature ranges.
Selection Notes
Select this component when a compact 8-bit MCU with integrated analog peripherals and touch sensing capability is required. The PSoC architecture allows for custom peripheral configuration, reducing external component count. Consider the 24 MHz performance limit and available I/O pins for system complexity. Evaluate power consumption profiles against the 2.4 V to 5.25 V operating range for battery or mains-powered designs.
Part Context
This device belongs to the Infineon CY8C21x34 series of Programmable System-on-Chip (PSoC) mixed-signal controllers. These controllers combine an 8-bit CPU with configurable analog and digital blocks, offering high flexibility for various embedded applications. The series is designed to minimize board space and development time by integrating multiple functions into a single chip.
Replacement Considerations
Consult Infineon's official cross-reference tools for verified substitutes. Potential alternatives within the same family may include variants with different pin counts or memory sizes, such as the CY8C21234A or CY8C21334, depending on specific peripheral requirements.
