CY8C20140-SX2I

Overview

The CY8C20140-SX2I is a PSoC Low Power Programmable System-on-Chip manufactured by Cypress Semiconductor Corp. It integrates an 8-bit CPU core with configurable analog and digital peripherals on a single die. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It features programmable interconnects allowing flexible routing between analog blocks, digital logic, and I/O pins. The architecture enables the implementation of complex mixed-signal applications while minimizing external component count.

Feature Summary

• Integrates configurable analog and digital peripherals for mixed-signal processing
• Supports low-power operation suitable for battery-powered devices
• Features programmable interconnects for flexible hardware customization

Applications

• Industrial control systems requiring mixed-signal interfaces
• Portable consumer electronics with power constraints
• Sensor interface modules in IoT end-nodes

Procurement Notes

Verify the specific suffix 'SX2I' against official Infineon or Cypress datasheets to confirm package type and temperature grade. Ensure compatibility with existing firmware libraries as PSoC architectures require specific configuration tools. Cross-reference pinouts if replacing legacy components to avoid layout mismatches.

Selection Notes

Select this component when a single-chip solution for mixed-signal tasks is required to reduce board space. Compare performance against standard microcontrollers if high-speed digital processing is needed, as PSoC cores prioritize peripheral flexibility over raw computational speed. Verify available development tool support for the specific PSoC generation.

Part Context

This part belongs to the Cypress PSoC 3 family, which combines a CyM8 CPU with reconfigurable analog and digital blocks. The series is designed for applications needing custom hardware accelerators without FPGA complexity. Cypress Semiconductor was acquired by Infineon Technologies, so current documentation may be hosted under the Infineon brand.

Replacement Considerations

Direct replacements are limited due to the proprietary PSoC architecture. Evaluate other PSoC 3 variants with different pin counts or memory sizes. Generic MCU replacements require significant firmware redesign and additional external components for analog functions.
