CY8C27643-24LTXI

Overview

The CY8C27643-24LTXI is an 8-bit microcontroller within the PSoC 1 family, utilizing CMOS technology and the M8C core. It features 16 kB of Flash program memory and 256 bytes of SRAM data RAM. The device operates on a supply voltage range of 3 V to 5.25 V with a maximum clock frequency of 24 MHz. It is housed in a 32-pin QFN package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Integrates configurable digital and analog peripherals for system-level flexibility
Combines an 8-bit microcontroller with embedded Flash and SRAM memory
Supports CapSense touch sensing capabilities for user interface applications

Applications

Consumer electronics requiring low pin count and mixed-signal integration
Industrial equipment control systems
Communications devices needing programmable logic interfaces

Procurement Notes

Verify the specific suffix 'LTXI' against official Infineon documentation to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with current datasheets to validate availability status and production lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when a compact 32-pin QFN form factor is required alongside integrated analog and digital programmability. It is suitable for designs needing CapSense functionality without external sensors. Compare memory sizes and I/O counts against other PSoC 1 variants to ensure optimal resource allocation for the specific application constraints.

Part Context

This part belongs to the Cypress Semiconductor (now Infineon) PSoC 1 series, designed as a complete system-on-chip solution. The series emphasizes design flexibility by allowing users to configure peripherals via software, reducing board space and component count. It targets markets including consumer, computation, communications, automotive, and industrial equipment.

Replacement Considerations

Check for CY8C27643-24PVXI for SSOP packaging or CY8C27643-24LFXI for alternative QFN variations. Verify pin compatibility and memory specifications when substituting.
