CY8C26443-24SIT

Overview

The CY8C26443-24SIT is a Programmable System-on-Chip (PSoC) device from the CY8C26xxx family, featuring an M8C processor core with speeds up to 24 MHz. It integrates 16 KB of Flash program memory and 256 bytes of SRAM data storage. The device includes configurable analog and digital peripheral blocks, supporting up to 11-bit Delta-Sigma ADCs, 9-bit DACs, and various digital communication interfaces. Operating voltage ranges from 3.0 V to 5.25 V, with extended operation down to 1.0 V using the on-chip switch mode voltage pump.

Feature Summary

• Configurable mixed-signal array allows user-defined analog and digital peripheral blocks without custom silicon design.
• Integrated M8C Harvard architecture processor supports fast multiply/accumulate operations and flexible addressing modes.
• On-chip precision clocking provides internal oscillators and external crystal support for system timing.
• Flash memory technology enables in-system serial programming and partial updates with high endurance.

Applications

• General-purpose embedded control systems
• Smart sensing applications requiring programmable analog front ends
• Human-machine interface designs with LCD direct drive capabilities

Procurement Notes

Verify component authenticity through authorized Infineon or Cypress distribution channels. Confirm that the specific ordering suffix matches the required package type and temperature range. Ensure compliance with RoHS directives as indicated in the official datasheet specifications before procurement.

Selection Notes

Select this component when a single-chip solution replaces multiple discrete MCU and analog components. Consider the CY8C27xxx series for new designs as the CY8C26xxx family is not recommended for new implementations. Evaluate pin count and I/O requirements against the specific device variant within the family.

Part Context

This device belongs to the PSoC 2 family of programmable system-on-chips manufactured by Infineon Technologies (formerly Cypress Semiconductor). It represents a configurable mixed-signal array architecture designed to reduce board space and development time by integrating CPU, memory, and customizable peripherals.

Replacement Considerations

Official documentation recommends using the CY8C27xxx series for new designs instead of the CY8C26xxx family. Verify functional compatibility if substituting with other members of the CY8C26xxx family based on memory size and pin configuration.
