CY8C22345H-24PVXA

Overview

The Infineon CY8C22345H-24PVXA is an automotive-grade PSoC microcontroller featuring the M8C processor running at up to 24 MHz. It integrates 16 KB of Flash program memory and 1 KB of SRAM data storage within a 48-pin TQFP package. The device supports AEC-Q100 Grade A qualification, operating between 3.0 V and 5.25 V across a -40 °C to +85 °C temperature range. Key resources include six analog Type 'E' blocks, eight digital PSoC blocks, and a 10-bit SAR ADC. This specific variant includes Immersion TouchSense Haptics Technology for ERM drive control.

Feature Summary

• Integrates Immersion TouchSense Haptics Technology for ERM motor drive control
• Features configurable analog and digital PSoC blocks for custom peripheral creation
• Includes a 10-bit SAR ADC optimized for embedded control applications
• Supports flexible clocking with internal oscillators and optional PLL

Applications

• Automotive haptic feedback systems
• Embedded control units requiring analog signal processing
• Industrial automation controllers
• Smart sensor interfaces

Procurement Notes

Verify the complete part number including suffixes against official Infineon documentation to ensure correct package type and temperature grade. Confirm that the specific ordering code matches the required automotive qualification level. Check for any recent obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring integrated haptic feedback capabilities alongside programmable analog and digital logic. Ensure the application benefits from the configurable PSoC architecture to reduce bill-of-materials count. Verify that the 24 MHz processing speed and available I/O pins meet the system's timing and connectivity requirements.

Part Context

This device belongs to the Automotive PSoC Programmable System-on-Chip family, specifically the CY8C22x45H series. These devices are designed to replace multiple traditional MCU-based components with a single chip. The 'H' designation indicates the inclusion of specialized haptics technology, distinguishing it from standard CY8C22345 variants.

Replacement Considerations

Direct replacements within the same family include the CY8C22345 (without haptics) or CY8C22645. Cross-family migration to newer PSoC generations requires significant architectural redesign due to differences in CPU cores and peripheral configurations.
