CY8C21223-24SXI

Overview

The Infineon CY8C21223-24SXI is an 8-bit microcontroller based on the PSoC architecture, featuring an 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 an industrial temperature range from -40 °C to +85 °C. It provides up to 16 GPIO pins and integrates four digital PSoC blocks for configurable peripherals such as timers, counters, PWMs, UART, and SPI. The analog system consists of two Type E analog blocks supporting comparators and a single or dual 10-bit ADC.

Feature Summary

Procurement Notes

Verify the specific package type and suffix against official Infineon documentation to ensure compatibility with your board design. Confirm that the ordering code matches the required pinout and environmental specifications. Check for any recent revisions or errata documents that may impact implementation details. Ensure development tools are compatible with the selected device variant.

Selection Notes

Select this component when a highly configurable mixed-signal solution is required to reduce bill of materials count. Consider the CY8C21223-24SXI for designs needing flexible analog-to-digital conversion and digital logic integration within a compact footprint. Evaluate the available GPIO count and memory size against application requirements before finalizing the choice.

Part Context

The CY8C21223-24SXI belongs to the CY8C21x23 family of PSoC Programmable System-on-Chip devices. This family is designed to replace multiple traditional MCU-based components with a single programmable chip. It combines an 8-bit CPU with configurable analog and digital blocks, offering design flexibility and reduced system complexity compared to fixed-function microcontrollers.

Replacement Considerations

Consult official Infineon documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when considering alternatives.
