CY8C21534-12PVXET

Overview

The CY8C21534-12PVXET is an automotive-grade PSoC microcontroller from Infineon Technologies, featuring the M8C processor core operating at speeds up to 12 MHz. It integrates 8 KB of Flash program storage and 512 bytes of SRAM data memory within a 28-pin SSOP package. The device supports a supply voltage range of 4.75 V to 5.25 V and operates across an extended temperature range of –40 °C to +125 °C. Key peripherals include four analog Type E PSoC blocks for ADC and comparator functions, four digital PSoC blocks for timers and communication interfaces, and CapSense capability.

Feature Summary

• AEC Q100 qualified for automotive electronics applications
• Configurable analog and digital system resources via PSoC architecture
• Integrated capacitive sensing (CapSense) application capability
• Flexible on-chip memory with in-system serial programming support

Applications

• Automotive body control modules
• Instrumentation clusters
• Touch sensing interfaces
• Low-power automotive sensors

Procurement Notes

Verify component authenticity through authorized distributors or Infineon directly. Confirm the specific suffix 'T' indicates tape and reel packaging. Check current lifecycle status as automotive components may face discontinuation notices. Ensure environmental compliance documentation matches project requirements.

Selection Notes

Select this part when AEC Q100 qualification and extended temperature operation are mandatory. The 28-pin SSOP package offers a balance of I/O count and form factor. Consider the limited analog block functionality compared to higher-end PSoC families if complex signal processing is required.

Part Context

This component belongs to the CY8C21x34 family of PSoC devices designed specifically for automotive environments. It shares architectural similarities with the CY8C21334 but provides additional GPIOs due to the larger 28-pin package. The device replaces multiple discrete MCU and peripheral chips in automotive designs.

Replacement Considerations

CY8C21534-12PVXE is a tube-packaged equivalent. CY8C21334-12PVXET is a pin-compatible alternative with fewer I/O pins. Verify software compatibility when migrating between these variants.
