CY8C21534-12PVXE

Overview

The CY8C21534-12PVXE 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 an operating voltage range of 4.75 V to 5.25 V and functions reliably in extended temperature environments ranging from –40 °C to +125 °C.

Feature Summary

• AEC Q100 qualified for automotive electronics applications
• Configurable analog and digital system blocks for custom peripheral creation
• Supports capacitive sensing application capabilities via complex peripherals
• Includes flexible on-chip memory with partial flash update and protection modes

Applications

• Automotive electronic systems requiring extended temperature operation
• Capacitive touch sensing interfaces
• Systems utilizing configurable analog-to-digital conversion
• Applications requiring programmable digital logic and timers

Procurement Notes

Verify that the specific part number suffix corresponds to the required package type and temperature grade. Confirm AEC Q100 qualification status if automotive compliance is mandatory. Ensure compatibility with existing design tools such as PSoC Designer software before procurement.

Selection Notes

Select this component when fixed-function microcontrollers lack the necessary configurability for mixed-signal designs. The PSoC architecture allows customization of analog and digital resources, reducing bill-of-materials complexity. Consider the 12 MHz processing speed and available I/O count against specific application requirements.

Part Context

This device belongs to the CY8C21x34 family of Programmable System-on-Chips. It combines a Harvard-architecture CPU with reconfigurable analog and digital blocks. The architecture enables designers to implement custom peripherals, replacing multiple discrete components with a single chip solution.

Replacement Considerations

CY8C21534-24PVXI offers similar features but operates at higher clock frequencies.
