C161PILF3VCABXUMA1

Overview

The C161PILF3VCABXUMA1 is a 16-bit microcontroller from the Infineon C166 C16xx family. It features a ROMless program memory architecture and an internal oscillator. The device operates at a clock speed of 20MHz with a supply voltage range of 3V to 3.6V. It includes 76 I/O lines, 3K x 8 RAM, and four 10-bit A/D converters. Connectivity options include EBI/EMI, I2C, SPI, and UART/USART interfaces. The component is housed in a PG-TQFP-100-1 package and supports a temperature range of -40°C to 85°C.

Feature Summary

• ROMless architecture for flexible code execution
• Integrated internal oscillator for clock generation
• Multiple communication interfaces including I2C, SPI, and UART

Applications

• Automotive electronic control units
• Industrial motor control systems
• Embedded sensor processing nodes

Procurement Notes

Verify the exact suffix 'BX' against official manufacturer documentation, as standard listings typically use 'FX'. Confirm current production status, as similar C161PI variants are marked obsolete. Ensure compatibility with existing board layouts for the 100-pin TQFP package before procurement.

Selection Notes

Select this component when a 16-bit C166 core is required with low-voltage operation around 3.3V. The absence of on-chip program memory necessitates external storage solutions. Verify that the 20MHz performance meets system timing requirements and that the 100-pin footprint aligns with the target PCB design.

Part Context

This part belongs to the C161PI series within the broader C16xx microcontroller portfolio. It shares architectural similarities with other C166 derivatives but is distinguished by its specific pin count, voltage rating, and package type. The series targets applications requiring robust 16-bit processing capabilities in compact form factors.

Replacement Considerations

Public confirmed substitute part numbers are not available for this specific variant.
