CY8C21223-24SXIT

Overview

The CY8C21223-24SXIT is an 8-bit microcontroller from the Infineon PSoC family, featuring the M8C processor core with speeds up to 24 MHz. It includes 4 KB of Flash program storage and 256 bytes of SRAM data storage. The device operates within a voltage range of 2.4 V to 5.25 V and supports industrial temperatures from -40 °C to +85 °C. It provides up to 16 GPIO pins in a 16-pin SOIC package.

Feature Summary

• Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
• M8C Harvard-architecture processor supporting full-duplex UART, SPI, and I2C communication
• On-chip switch mode pump enabling operation from single battery cells down to 1.0 V
• Flexible memory protection modes with in-system serial programming capability

Applications

• Battery-powered portable devices utilizing low-voltage operation
• Industrial control systems requiring programmable logic interfaces
• Consumer electronics needing customizable analog signal processing
• General-purpose embedded applications with mixed-signal requirements

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets RoHS compliance standards for your region. Ensure development tools like PSoC Designer are compatible with the selected silicon revision before finalizing procurement decisions.

Selection Notes

Select this part when fixed-function peripherals are insufficient for application needs. The PSoC architecture allows replacing multiple discrete components with a single chip. Consider the available digital and analog blocks to ensure sufficient resources for complex signal routing and processing tasks without external hardware.

Part Context

This component belongs to the CY8C21x23 series of Programmable System-on-Chips. It shares the M8C core and basic architecture with variants like the CY8C21123 and CY8C21323, differing primarily in pin count and I/O availability. The series emphasizes flexibility through configurable analog and digital blocks.

Replacement Considerations

Direct substitutes include other CY8C21x23 variants such as CY8C21123 or CY8C21323, depending on pin compatibility. Cross-family replacements require careful evaluation of register compatibility and peripheral availability.
