CY8C21223-24LGXIT

Overview

The CY8C21223-24LGXIT is a PSoC Programmable System-on-Chip featuring an M8C processor operating up to 24 MHz. It includes 4 KB Flash and 256 bytes SRAM. The device provides four digital PSoC blocks for timers, counters, PWMs, UART, SPI, and I2C. Four analog Type E blocks support comparators and 10-bit ADCs. Operating voltage ranges from 2.4 V to 5.25 V, or down to 1.0 V with the on-chip switch mode pump. Industrial temperature range is -40 °C to +85 °C.

Feature Summary

Configurable analog and digital peripherals enable custom system integration on a single chip.
On-chip switch mode pump allows operation from a single battery cell at low voltages.
Flexible GPIO supports various drive modes and interrupt configurations.

Applications

Battery-powered consumer devices
Industrial control systems
General-purpose embedded applications

Procurement Notes

Verify the component against official Infineon/Cypress datasheet specifications. Confirm package type and marking codes match the ordered part number. Ensure environmental compliance documentation aligns with project requirements.

Selection Notes

Select this model when design flexibility for mixed-signal applications is required. The programmable architecture reduces external component count. Consider the switch mode pump feature for extended battery life in portable designs.

Part Context

This component belongs to the PSoC 21x23 family. It integrates an 8-bit CPU with configurable analog and digital blocks. The architecture allows designers to implement specific peripheral functions without fixed hardware constraints.

Replacement Considerations

Check CY8C21123 and CY8C21323 for pin-compatible alternatives within the same family. Verify memory size and I/O count differences before substitution.
