CY8C20055-24SXIT

Application Specific Microcontrollers Overview

The CY8C20055-24SXIT is an 8-bit microcontroller from the PSoC 1 family, manufactured by Infineon Technologies. It utilizes the M8C core and features a maximum clock frequency of 24 MHz. The device integrates 16 kB of Flash program memory and 1 kB of SRAM data RAM. Key peripherals include CapSense technology for touch sensing, I2C and SPI interfaces, and programmable timers. It operates within a voltage range of 3 V to 5.25 V and supports a -40 °C to +85 °C operating temperature range.

Application Specific Microcontrollers Feature Summary

• M8C 8-bit CPU Core with up to 24 MHz operation
• 16 kB Flash and 1 kB SRAM memory configuration
• Integrated CapSense system for capacitive touch sensing
• On-chip I2C and SPI communication interfaces

Application Specific Microcontrollers Applications

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'IT' corresponds to the required tape-and-reel packaging quantity when sourcing. Confirm that the component meets RoHS compliance standards as indicated in manufacturer documentation. Ensure the supply chain source provides valid traceability for the Infineon/Cypress product line.

Application Specific Microcontrollers Selection Notes

Select this model when a 16 kB Flash size and 1 kB RAM are sufficient for the application logic. The 24 MHz speed is suitable for moderate processing loads. Verify that the available GPIO count in the 16-pin package meets the interface requirements for I2C, SPI, and CapSense channels.

Application Specific Microcontrollers Part Context

This part belongs to the PSoC CY8C20xx7/S series, which combines analog and digital peripherals on a single chip. The CY8C20055 variant specifically denotes the 16 kB Flash capacity within this family, distinguishing it from lower-capacity models like the CY8C20034.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same package and pinout include other members of the CY8C20xx7/S family with equivalent or larger memory sizes, such as the CY8C20237 or CY8C20247, provided the software is compatible.
