CY8C27643-24LTXIT

Overview

The CY8C27643-24LTXIT is an 8-bit microcontroller within the Infineon 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 supports a maximum clock frequency of 24 MHz and provides 24 I/O pins in a 48-pin SSOP package. Operating voltage ranges from 3 V to 5.25 V, with a functional temperature range spanning -40°C to +85°C.

Feature Summary

• Integrates configurable analog and digital peripherals for mixed-signal system-on-chip applications
• Combines an 8-bit microcontroller with embedded memory and programmable logic blocks
• Supports surface-mount installation via standard SSOP packaging

Applications

• Consumer electronics control systems
• Industrial equipment monitoring
• Communication interface modules

Procurement Notes

Verify the specific suffix LTXIT against official datasheets to confirm tape-and-reel packaging and moisture sensitivity classification. Ensure compatibility with existing PCB footprints for 48-pin SSOP components. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a low pin-count solution with integrated analog capabilities is required. The 24 MHz speed and 16 kB memory suit moderate processing tasks. Compare against CY8C27643 variants with different packages or temperatures if environmental conditions exceed standard industrial limits.

Part Context

This part belongs to the CY8C27xxx series of Programmable System-on-Chip devices. These controllers merge CPU, memory, and customizable peripheral blocks into a single silicon die, reducing external component count and board space compared to discrete microcontroller designs.

Replacement Considerations

Check for CY8C27643 variants with alternative suffixes indicating different packaging options such as QFN or TQFP. Verify that substitute parts maintain identical memory sizes and I/O configurations to ensure software compatibility.
