CY8C22345-24SXIT

Overview

The Infineon CY8C22345-24SXIT is an 8-bit microcontroller within the PSoC 1 family, featuring a 24 MHz M8C processor. It includes 16 KB of Flash program memory and 1 KB of SRAM data storage. The device offers up to 38 configurable GPIOs and supports industrial temperature ranges from -40 °C to +85 °C with operating voltages between 3.0 V and 5.25 V.

Feature Summary

• Configurable analog and digital system blocks allow custom peripheral creation
• Integrated CapSense technology for capacitive touch sensing applications
• Supports multiple communication interfaces including I2C, SPI, and UART

Applications

• Capacitive touch interface controllers
• Industrial sensor nodes
• Low-power embedded control systems

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints before procurement. Confirm availability status through authorized distributors as supply levels may fluctuate.

Selection Notes

Select this component when application requirements demand high configurability of analog and digital resources. The integrated CapSense capability makes it suitable for touch-sensitive user interfaces. Verify that the 16 KB Flash and 1 KB SRAM meet the memory footprint needs of the target firmware.

Part Context

This part belongs to the CY8C22x45 series of PSoC devices, which provide eight digital blocks and six analog blocks. It shares architectural similarities with the CY8C21345 and CY8C22545 but differs in pin count and I/O capacity. The SOIC-28 package provides a compact solution for space-constrained designs.

Replacement Considerations

CY8C21345-24SXIT: Compatible alternative with reduced I/O count (24 pins). CY8C22545-24AXIT: Higher pin count variant (44 pins) with increased I/O capacity.
