CY8C28545-24AXI

Overview

The CY8C28545-24AXI is an 8-bit microcontroller within the PSoC 1 family, featuring an M8C core operating at up to 24 MHz. It integrates 16 KB of Flash program storage and 1 KB of SRAM data memory. The device supports a supply voltage range of 3.0 V to 5.25 V, with operation down to 1.5 V using an on-chip switched mode pump. It includes CapSense IO capabilities, two hardware I2C resources, and operates within an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• Configurable analog and digital PSoC blocks allow custom peripheral creation
• CapSense technology enables capacitive sensing applications
• On-chip switched mode pump supports low voltage battery operation
• Integrated system resources include watchdog timers and low voltage detection

Applications

• Consumer electronics requiring mixed-signal control
• Industrial equipment monitoring systems
• Communications interface modules
• Computational devices with sensor integration needs

Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific ordering suffix matches project requirements for package type and temperature grade. Check current lifecycle status as availability may vary. Ensure compliance with RoHS directives and relevant regional regulations before procurement.

Selection Notes

Evaluate resource allocation against application needs, noting this subgroup offers full feature sets including CapSense. Compare pin counts and I/O configurations with alternative CY8C28xxx variants. Consider development tool compatibility with PSoC Designer software. Assess power consumption profiles relative to the switched mode pump capability for battery-operated designs.

Part Context

This component belongs to the CY8C285xx subgroup of the PSoC 1 Programmable System-on-Chip family. It shares architectural similarities with CY8C28243, CY8C284xx, and CY8C286xx devices but offers distinct resource configurations. The part represents a solution combining an 8-bit processor with reconfigurable analog and digital peripherals on a single chip.

Replacement Considerations

Consult official documentation for qualified substitute part numbers within the CY8C28xxx series. Verify pin-to-pin compatibility and resource equivalence before substitution. Review errata sheets for any silicon revisions affecting functionality.
