CY8C28403-24PVXIT

Overview

The CY8C28403-24PVXI is an Infineon Technologies PSoC 1 mixed-signal controller featuring the M8C core operating at 24 MHz. It integrates 16 KB Flash program memory and 1 KB SRAM data storage within a 28-pin SSOP package. The device supports a supply voltage range of 3.0 V to 5.25 V and operates across an industrial temperature range of -40 °C to +85 °C. Key peripherals include up to 24 I/O pins, four 14-bit Delta-Sigma ADCs, two hardware I2C interfaces, and multiple digital blocks for configurable PWM, UART, and SPI functions.

Feature Summary

• Integrates reconfigurable analog and digital PSoC blocks allowing custom peripheral creation
• Features a high-speed 24 MHz M8C Harvard architecture processor with multiply-accumulate capability
• Includes on-chip switched mode pump enabling operation from single-cell battery sources
• Supports in-system serial programming and partial flash updates

Applications

• Industrial control systems
• Communication base station management
• White home appliances

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Ensure compatibility with existing design tools such as PSoC Designer when integrating this component into new or legacy projects.

Selection Notes

Select this model for applications requiring flexible mixed-signal processing within a compact footprint. The CY8C28xxx series offers segmented resource options, allowing designers to utilize only necessary analog and digital blocks. Verify that the 24 I/O count and available ADC channels meet system requirements before finalizing the part number selection.

Part Context

This component belongs to the CY8C28xxx subgroup of the PSoC 1 family. These devices share a common architecture but vary in resource allocation. The CY8C284xx subgroup specifically provides full analog capabilities including four synchronized Delta-Sigma ADCs and twelve regular analog blocks, distinguishing it from other subgroups with limited analog resources.

Replacement Considerations

Consult official replacement lists for obsolete parts. Cross-reference pinouts and electrical specifications carefully when substituting components.
