CY8C21345-12PVXE

Overview

The Infineon CY8C21345-12PVXE is an automotive-grade PSoC microcontroller featuring the M8C core operating at 12 MHz. It integrates 8 KB of Flash program memory and 512 bytes of SRAM data storage within a 28-pin SSOP package. The device supports AEC-Q100 Grade A qualification, functioning reliably between 3.0 V and 5.25 V across a temperature range of -40 °C to +85 °C.

Feature Summary

• AEC Q100 qualified for automotive electronics applications
• Configurable analog and digital system-on-chip architecture
• Integrated CapSense resource with dedicated scanning timers

Applications

• Automotive body control modules
• Sensor interface systems
• Capacitive touch sensing controllers

Procurement Notes

Verify the specific suffix '12PVXE' against official ordering guides to confirm pinout compatibility and package type. Ensure the design accounts for the 12 MHz clock speed limitation inherent in this variant compared to higher-speed models. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when automotive reliability standards are mandatory alongside programmable I/O flexibility. The 12 MHz speed suits moderate processing loads where power efficiency is prioritized over raw throughput. Consider the limited 512-byte RAM size for complex algorithm implementation requirements.
