CY8C20110-LDX2I

Overview

The CY8C20110-LDX2I is a member of the PSoC™ 2 family, integrating an 8-bit 8051-compatible microcontroller with programmable analog and digital blocks. It features up to 32 KB of Flash memory and 1 KB of SRAM. The device includes one SAR ADC with 10-bit resolution and supports multiple communication interfaces such as SPI, I2C, and UART. Operating voltage ranges from 1.71 V to 5.5 V, with an industrial temperature range of -40 °C to 85 °C. Peak reflow temperature is rated at 260 °C, and it utilizes Ni/Pd/Au ball finish for CSP packaging.

Feature Summary

• Integrates programmable analog and digital subsystems within a single chip architecture
• Supports flexible communication protocols including SPI, I2C, and UART via configurable digital blocks
• Includes a successive approximation register (SAR) analog-to-digital converter for signal acquisition

Applications

• Battery-powered portable devices requiring low power consumption
• Industrial control systems needing mixed-signal processing
• Consumer electronics with interface connectivity requirements

Procurement Notes

Verify the specific ordering suffix against Infineon's official datasheet to confirm package type, temperature grade, and lead finish. Ensure compatibility with existing PCB footprint and reflow profiles. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through current documentation.

Selection Notes

Select this component when an 8-bit MCU with integrated programmable analog capabilities is required. Consider the pin count and available GPIO resources relative to system interface needs. Evaluate power supply constraints against the 1.71 V to 5.5 V operating range. Verify that the Flash and SRAM sizes meet application code and data storage requirements.

Part Context

This part belongs to the PSoC™ 2 family, which combines an 8051 core with Cypress's Programmable System-on-Chip technology. It targets applications requiring cost-effective mixed-signal solutions. The family emphasizes flexibility through hardware-configurable peripherals, reducing external component count compared to standard MCU architectures.

Replacement Considerations

Check for direct pin-to-pin replacements within the PSoC™ 2 series or upgraded PSoC™ 3/4/5LP families if enhanced performance is needed. Verify software compatibility when migrating to newer architectures with different instruction sets or peripheral configurations.
