The device offers up to 16 configurable GPIO pins and supports multiple communication interfaces including I2C, SPI, and UART. Analog capabilities include a 10-bit ADC and comparators. It operates within a voltage range of 2.4 V to 5.25 V and functions in temperatures from -40 °C to +85 °C.

Feature Summary

• Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
• M8C Harvard-architecture processor supporting high-speed operation at low power
• Flexible on-chip memory with in-system serial programming and partial flash updates
• Programmable pin configurations with various drive modes and interrupt capabilities

Applications

• Low-cost single-chip replacements for traditional MCU-based systems
• Applications requiring customizable analog signal processing such as sensor interfacing
• Systems needing flexible digital peripherals like PWMs, timers, and counters
• Battery-powered devices utilizing the on-chip switch mode pump for extended operation

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with PSoC Designer development tools for configuration. Check for any silicon errata related to frequency tolerance at extreme temperatures before finalizing design integration.

Selection Notes

Select this component when a balance of analog programmability and digital flexibility is required in a compact form factor. Consider the limited number of analog blocks compared to higher-end PSoC families if complex mixed-signal designs are needed. Evaluate the 24 MHz clock speed against application timing requirements.

Part Context

This part belongs to the CY8C21x23 series within the broader PSoC 2 portfolio. It shares architectural similarities with other members like the CY8C21323-24PVXI but differs in packaging or tape-and-reel availability indicated by the suffix. It serves as a versatile solution for embedded control tasks requiring programmable logic.

Replacement Considerations

Direct substitutes may include other CY8C21323 variants with different packaging options such as CY8C21323-24PVXI. Cross-family migration to CY8C24x23A or CY8C29x66 requires significant architectural changes due to differences in block counts and memory sizes.
