CY8C20140-LDX2I

Overview

The CY8C20140-LDX2I is a programmable system-on-chip microcontroller from Infineon Technologies, belonging to the PSoC 2 family. It integrates an M8C CPU core with programmable analog and digital blocks on a single die. The device features 32 kByte of Flash program memory and 2 kByte of SRAM data memory. It operates within a voltage range of 1.71 V to 5.5 V and supports industrial temperature ranges. The component utilizes a TSSOP-28 package for surface mount installation.

Feature Summary

• Integrates programmable analog and digital blocks for custom peripheral creation
• Includes an M8C CPU core for efficient code execution
• Supports flexible communication interfaces including I2C and SPI

Applications

• General-purpose embedded control systems
• Sensor interface circuits
• Human-machine interface modules

Procurement Notes

Verify the specific suffix LDX2I against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for TSSOP-28 packages. Confirm supply chain availability through authorized distributors as lead times may vary. Check for RoHS compliance status in current datasheets before finalizing procurement plans.

Selection Notes

Select this component when a low-pin-count solution with mixed-signal capabilities is required. The PSoC architecture allows replacing multiple discrete components with a single chip. Consider the available GPIO count and memory size relative to application requirements. Evaluate the programming toolchain support for the M8C core during the design phase.

Part Context

This part belongs to the PSoC 2 family, which focuses on cost-effective mixed-signal integration. It serves as a bridge between simple 8-bit microcontrollers and more complex high-performance SoCs. The family is designed for applications requiring analog signal conditioning alongside digital logic processing in compact form factors.

Replacement Considerations

Check for direct pin-to-pin replacements within the PSoC 2 series such as CY8C20x40 variants. Verify functional equivalence if upgrading to newer families like PSoC 4 or PSoC 5LP, noting architectural differences between M8C and ARM Cortex-M cores.
