C167CSL40MCAKXQLA1

Overview

The C167CSL40MCAKXQLA1 is a 16-bit microcontroller from the Infineon C166 family, operating at a maximum frequency of 40 MHz. It features a 32 KByte on-chip mask ROM, 3 KByte IRAM, and 8 KByte XRAM within a 16 MBytes linear address space. The device includes two CAN interfaces (Rev. 2.0B), a 24-channel 10-bit ADC, PWM units, and capture/compare modules. It utilizes a 144-pin MQFP package and supports up to 111 general-purpose I/O lines with selectable thresholds.

Feature Summary

• High-performance 16-bit CPU with a 4-stage pipeline and single-cycle context switching.
• Dual on-chip CAN interfaces supporting Rev. 2.0B active protocols.
• Integrated analog-to-digital conversion with 24 channels and programmable timing.
• Flexible external bus controller supporting multiplexed and demultiplexed modes.

Applications

• Automotive electronic control units requiring CAN communication.
• Industrial motor control systems utilizing PWM and capture/compare features.
• Embedded applications needing high-speed data acquisition via the ADC.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product catalog to confirm availability and exact pinout compatibility. Ensure that the design accounts for the 5V supply voltage requirements during normal operation. Confirm that the 144-pin MQFP package dimensions align with the target PCB layout constraints.

Selection Notes

Select this component when a 16-bit architecture with integrated CAN controllers is required. Consider the 40 MHz operational speed for processing-intensive tasks. Evaluate the available memory sizes against application code and data storage needs. Verify that the peripheral count, including timers and ADC channels, meets system interface requirements.
