CY8C28445-24PVXI

Overview

The CY8C28445-24PVXI is an 8-bit microcontroller from the Infineon PSoC 1 family, utilizing the M8C core. It features 16 KB of Flash program storage and 1 KB of SRAM data memory. The device supports a maximum clock frequency of 24 MHz and operates within a voltage range of 3.0 V to 5.25 V. It includes up to 12 digital blocks and 16 analog blocks for configurable peripherals. The component is housed in a 28-pin SSOP package and supports industrial temperature ranges.

Feature Summary

• Configurable analog system with up to 16 blocks supporting ADCs, DACs, amplifiers, and filters
• Reconfigurable digital system with up to 12 blocks for timers, counters, PWMs, and communication interfaces
• Integrated M8C processor core with Harvard architecture and hardware multiply/accumulate capability
• Flexible GPIO configuration with multiple drive modes and interrupt capabilities on all pins

Applications

• Wireless measurement systems for environmental monitoring
• Soil gas and environment sensing applications
• General-purpose mixed-signal control systems
• Industrial sensor interface designs

Procurement Notes

Verify the specific ordering suffix PVXI confirms the 28-SSOP package and industrial temperature grade. Confirm RoHS compliance status through official documentation. Ensure compatibility with existing design tools such as PSoC Designer. Check for any relevant errata or silicon revisions that may impact implementation.

Selection Notes

Select this part when a mix of analog precision and digital flexibility is required in a compact form factor. The CY8C28445 subgroup offers the full feature set including CapSense and extensive analog resources. Consider pin count requirements against the 28-pin SSOP limitation. Evaluate if the 24 MHz speed meets real-time processing needs.

Part Context

This component belongs to the CY8C28xxx series of Programmable System-on-Chip devices. It shares architectural similarities with other members like the CY8C28445-24PVXI but differs in resource allocation and packaging. The series is designed to replace multiple discrete components with a single programmable chip.

Replacement Considerations

Direct substitutes include other CY8C284xx variants with compatible pinouts and memory sizes. Verify electrical specifications and peripheral availability when cross-referencing with similar Infineon PSoC 1 devices.
