CY8C21223-24LGXI

Overview

The CY8C21223-24LGXI is a PSoC Programmable System-on-Chip featuring an M8C processor operating at speeds up to 24 MHz. It includes 4 KB of Flash program storage and 256 bytes of SRAM data storage. The device provides four analog Type E PSoC blocks supporting dual 10-bit ADCs and comparators, alongside four digital PSoC blocks for timers, counters, and PWMs. Operating voltage ranges from 2.4 V to 5.25 V, with support for operation down to 1.0 V via the on-chip switch mode pump.

Feature Summary

• Configurable analog and digital logic blocks allow custom peripheral creation
• On-chip switch mode pump enables low-voltage battery operation
• Flexible GPIO supports various drive modes and interrupt configurations
• Integrated I2C master, slave, and multi-master communication

Applications

• Battery-powered consumer electronics
• Industrial control systems
• Smart sensing applications
• General-purpose microcontroller designs

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature range. Ensure compatibility with the PSoC Designer development environment. Confirm RoHS compliance status through current datasheets. Check for any silicon errata relevant to the specific revision before finalizing design integration.

Selection Notes

Select this component when a single-chip solution replaces multiple traditional MCU components. The architecture suits designs requiring configurable analog precision and flexible digital logic. Consider the 24 MHz processing speed and available memory for application complexity. Evaluate the need for the internal switch mode pump if operating from single-cell batteries.

Part Context

This part belongs to the CY8C21x23 family within the broader PSoC portfolio. It utilizes the M8C Harvard-architecture core. The device integrates programmable interconnects between analog and digital subsystems. It is designed to reduce inventory costs by replacing fixed-function peripherals with customizable hardware blocks.

Replacement Considerations

Consult official replacement guides for cross-referencing. Verify pinout compatibility and electrical specifications against potential substitutes. Ensure functional equivalence in analog block configuration and digital resource availability.
