C161PIL25FCABXUMA1

Overview

The C161PIL25FCABXUMA1 is a 16-bit microcontroller from the Infineon C166 family, specifically the C16xx series. It features a ROMless program memory architecture and operates at a clock speed of 25 MHz. The device includes 3K x 8 bytes of RAM and provides 76 I/O lines. It integrates four 10-bit A/D converters and supports interfaces including EBI/EMI, I2C, SPI, and UART/USART. Powered by 4.5V to 5.5V, it functions within -40°C to 85°C and uses a 100-LQFP package.

Feature Summary

• Supports high-speed internal processing with a 25 MHz operating frequency
• Provides flexible external bus interface capabilities for peripheral expansion
• Integrates multiple communication protocols for system connectivity

Applications

• Automotive engine control units
• Industrial motor drive systems
• Power electronics management

Procurement Notes

Verify the exact suffix 'CA' against official Infineon documentation to confirm pinout and voltage specifications. Confirm availability status as this component may be discontinued or superseded. Ensure the 100-LQFP package matches your PCB footprint requirements before ordering.

Selection Notes

Select this model when a 16-bit C166 core with 25 MHz performance is required. It is suitable for applications needing extensive I/O and external bus access without onboard program memory. Verify that the 4.5V to 5.5V supply range aligns with your system design.

Part Context

This part belongs to the C16xx family of 16-bit microcontrollers designed for automotive and industrial applications. These devices are known for their robustness and support for complex control tasks in power electronics and engine management systems.

Replacement Considerations

Check for direct substitutes like C161CSLFCAFXUMA1 or C161PILFCAFXUMA1 if available. Verify pin compatibility and software register mapping before switching components.
