CY8C26443-24PVIT

Overview

The CY8C26443-24PVIT is a Programmable System-on-Chip (PSoC) device from the CY8C26xxx family, manufactured by Infineon Technologies. It features an M8C processor core operating at up to 24 MHz. The device includes 16 kB of Flash program memory and 256 bytes of SRAM data storage. It provides 16 I/O pins in an SSOP-28 package. Analog capabilities include configurable Delta-Sigma ADCs with resolutions up to 11-bit. Digital PSoC blocks support UART, SPI, and timer functions. Operating voltage ranges from 3.0 V to 5.25 V, with a wide temperature range of -40°C to +85°C.

Feature Summary

• Configurable mixed-signal array allows user-defined analog and digital peripheral blocks without custom silicon design.
• Integrated M8C processor supports Harvard architecture with fast multiply/accumulate operations for efficient code execution.
• Flexible on-chip memory system includes Flash program storage with EEPROM emulation capabilities and in-system serial programming.
• Precision programmable clocking offers internal oscillators and external crystal options for accurate timing control.

Applications

• Consumer electronics requiring mixed-signal processing
• Industrial equipment monitoring and control systems
• Communications devices utilizing programmable interfaces

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm datasheet revision matches current manufacturing standards. Check RoHS compliance status prior to integration. Ensure proper ESD handling protocols during assembly. Validate pinout compatibility with target PCB layout specifications.

Selection Notes

Select this model when flexible analog-digital integration is required within a single chip. Consider the CY8C27xxx series for new designs as the CY8C26xxx family is not recommended for new applications. Evaluate memory requirements against the 16 kB Flash limit. Assess I/O count needs against the 16-pin availability in the SSOP-28 package.

Part Context

This component belongs to the Cypress Semiconductor (now Infineon) PSoC 2 family, specifically the CY8C26xxx series. These devices represent early generations of programmable system-on-chip technology, combining an 8-bit microcontroller with configurable analog and digital blocks. The family was designed to reduce bill-of-materials costs by integrating multiple discrete components into one IC.

Replacement Considerations

Official documentation states the CY8C26xxx family is Not Recommended for New Designs. The recommended replacement series is CY8C27xxx. Verify specific pin-to-pin compatibility and feature parity between the legacy CY8C26443 and the newer CY8C27xxx models before substitution.
