HI-3111PCTF

Controllers Overview

The HI-3111PCTF is a CAN bus controller manufactured by Holt Integrated Circuits Inc. It supports the CAN 2.0 protocol and features an SPI interface for communication with a microcontroller. The device operates within a supply voltage range of 4.75V to 5.25V and draws a typical current of 6.3mA. It is housed in a 44-pin QFN package measuring 7mm x 7mm. The component is rated for extended temperature operation, functioning reliably between -55°C and +125°C.

Controllers Feature Summary

• Supports CAN 2.0 protocol standards
• Utilizes SPI interface for host connectivity
• Designed for extended industrial temperature ranges

Controllers Applications

• Avionics systems requiring robust CAN control
• Industrial automation networks
• Automotive electronic modules

Controllers Procurement Notes

Verify the specific suffix 'PCTF' to ensure the correct 44-QFN package and extended temperature rating are obtained. Confirm that the supplier provides documentation confirming compliance with RoHS directives, as indicated in available product listings. Cross-reference the manufacturer part number against official Holt Integrated Circuits catalogs to avoid substitution errors with similar variants like the HI-3111PSTF.

Controllers Selection Notes

Select this component when a dedicated CAN controller with SPI interface is required for high-reliability applications. The extended temperature range makes it suitable for harsh environments where standard commercial grade parts may fail. Ensure the host system can accommodate the 44-pin QFN footprint and provides the necessary SPI clock speeds for optimal data throughput.

Controllers Part Context

This part belongs to the HI-3111 series of CAN controllers from Holt Integrated Circuits. The series includes variants such as the HI-3111PSTF, which integrates a transceiver. The HI-3111PCTF specifically focuses on the controller logic, providing the interface layer between the CAN bus physical layer and the digital processing unit.

Controllers Replacement Considerations

The HI-3111PSTF is a related variant but includes an integrated transceiver, differing in pinout and functionality. Direct replacement requires verifying if the external transceiver circuitry is still needed. No other direct substitutes are confirmed in public documentation.
