Structure and Working Principle
The SAK-C167CR0LM integrates a 16-bit C167 CPU core with on-chip memory, timers, and communication interfaces like UART, SPI, and CAN. The CPU operates at clock speeds up to 20 MHz, executing instructions efficiently for real-time control. Its Harvard architecture separates program and data memory, enhancing performance. Peripherals such as ADCs, PWM modules, and GPIOs enable interfacing with sensors and actuators. The microcontroller’s interrupt system prioritizes tasks, critical for automotive safety systems. Power management features reduce energy consumption during idle states, extending battery life in portable applications.
Key Features
The SAK-C167CR0LM stands out for its real-time capabilities, supported by a 16-bit core and deterministic interrupt handling. Integrated peripherals reduce external component count, simplifying PCB design. Its CAN interface is essential for automotive networks, while UART and SPI facilitate industrial communication. Low power modes (e.g., idle and power-down) optimize energy use, crucial for battery-operated devices. The microcontroller’s wide operating temperature range (-40°C to +125°C) ensures reliability in extreme conditions. On-chip flash memory allows firmware updates, enhancing flexibility over the product lifecycle.
Application Areas
In automotive systems, the SAK-C167CR0LM controls engine management units, transmission systems, and dashboard displays. Its robustness meets AEC-Q100 standards, ensuring longevity in vehicles. Industrial uses include PLCs, motor control, and HVAC systems, where real-time responsiveness is critical. Embedded applications leverage its communication interfaces for IoT edge devices and smart sensors. Medical devices benefit from its precision timing and low EMI. The microcontroller’s versatility makes it a go-to choice for developers needing reliability across diverse sectors.
Maintenance and Precautions
To ensure longevity, avoid exposing the SAK-C167CR0LM to excessive ESD or voltage spikes. Use proper decoupling capacitors near power pins to stabilize supply voltages. Heat sinks or airflow may be necessary in high-temperature environments to prevent thermal throttling. Firmware should include watchdog timers to recover from unexpected stalls. Regularly update development tools to maintain compatibility with newer compiler optimizations. For automotive applications, adhere to ISO 26262 functional safety guidelines during design.
B2B Procurement Guide
When sourcing the SAK-C167CR0LM, verify supplier authenticity to avoid counterfeit parts. Infineon’s authorized distributors provide traceability and technical support. Bulk purchases (100+ units) typically offer cost savings of 10-30%. Check lead times, as industrial demand may cause delays. Evaluate sample availability for prototyping. Confirm RoHS and REACH compliance if exporting to regulated markets. For long-term projects, secure multi-year supply agreements to mitigate price volatility.
