Feature Summary

• Programmable logic architecture for customized peripheral functions
• Compatible with 8-bit MCU ecosystems
• 64-pin TQFP surface-mount packaging

Applications

• 8-Bit MCU Peripherals

Procurement Notes

Verify the specific datasheet revision and electrical characteristics directly from STMicroelectronics official documentation before integration. Confirm that the 64-TQFP package footprint matches the target PCB layout requirements. Ensure compatibility with the intended 8-bit MCU family for proper interface signaling.

Selection Notes

Select this component when fixed-function peripherals are insufficient for an 8-bit MCU design. Evaluate the available programming tools and firmware libraries required to configure the internal logic. Compare pin count and package size against board space constraints to ensure the 64-TQFP form factor fits the application.

Part Context

This part belongs to the programmable peripheral IC category within STMicroelectronics' portfolio. It complements their range of microcontrollers by providing additional configurable hardware resources. These devices are typically used to offload simple logic tasks from the main processor.

Replacement Considerations

Check for direct pin-to-pin replacements within the same series. Verify if newer generations offer enhanced programming flexibility or improved performance metrics while maintaining physical compatibility.
