CY8C26643-24AI

Overview

The CY8C26643-24AI is an 8-bit microcontroller from the Infineon PSoC™ 1 family, utilizing the M8C processor core. It features 16KB of Flash program memory and 256 bytes of SRAM data storage. The device operates at a maximum clock frequency of 24 MHz with a supply voltage range of 3.0 V to 5.25 V. It includes 8 switch-capacitor analog blocks (Type B) and supports configurable digital peripherals.

Feature Summary

• Configurable mixed-signal array architecture integrating programmable analog and digital peripheral blocks
• On-board M8C Harvard architecture processor with fast multiply/accumulate capabilities
• Flexible on-chip memory with in-system serial programming and partial Flash update support
• Precision programmable clocking with internal oscillator options

Applications

• Consumer electronics requiring low pin-count system integration
• Industrial equipment control systems
• Communications devices needing programmable signal processing
• Computation modules for embedded applications

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure compliance with RoHS directives and relevant environmental standards before procurement.

Selection Notes

Select this component when a single-chip solution replacing multiple MCU-based components is required. Consider the CY8C26643-24AI for designs needing flexible analog/digital configuration and moderate I/O counts within the PSoC 1 ecosystem.

Part Context

This part belongs to the PSoC™ 1 CY8C26xxx series, designed as a Programmable System-on-Chip. It replaces discrete components by combining a CPU, Flash/SRAM, and configurable analog/digital blocks into one IC, targeting markets like consumer, computation, communications, automotive, and industrial equipment.

Replacement Considerations

Official documentation recommends using the CY8C27xxx series instead of the CY8C26xxx series for new designs.
