TS68C429AVF

Controllers Overview

The TS68C429AVF is a high-performance ARINC 429 controller manufactured by Microchip Technology, designed for multi-channel serial data communication. It features eight independent receiver channels and three independent transmitter channels, supporting data rates up to 2.5 Mbit/s. The device operates on a single 5V supply with low power consumption of 400 mW and supports a maximum operating frequency of 20 MHz. It includes an 8-message FIFO per transmitter channel and direct addressing of all registers. The component is packaged in a CQFP 132 ceramic quad flat pack.

Controllers Feature Summary

• Eight independent receiver channels with parallel-to-serial conversion and label control matrix validation
• Three independent transmitter channels equipped with 8-word FIFO memory and programmable gap control
• Full compatibility with the TS68K family microprocessor interface via a 16-bit data bus
• Support for vectored interrupts with daisy-chain capability for both receive and transmit functions

Controllers Applications

• Avionics systems requiring multi-channel ARINC 429 data bus interfacing
• Flight management computers integrating navigation and sensor data
• Military aircraft electronic warfare and communication subsystems

Controllers Procurement Notes

Verify the specific suffix 'VF' against official datasheets to confirm package type and temperature range. Ensure compliance with MIL-STD-883 Class B screening requirements if specified for your application. Confirm availability through authorized distributors as this component may be subject to long-term supply agreements.

Controllers Selection Notes

Select the TS68C429AVF when multiple ARINC 429 channels are required within a single integrated circuit. Consider its compatibility with the TS68K processor family for seamless integration. Evaluate thermal resistance characteristics for heat dissipation in enclosed avionics environments. Verify that the 5V logic levels meet system voltage requirements.

Controllers Part Context

The TS68C429A serves as an enhanced version of the EF 4442, providing increased channel density for complex avionics architectures. It replaces traditional discrete solutions or lower-density controllers, reducing board space and power consumption. The device is widely used in modern digital flight control systems where reliable, high-speed serial communication is critical.

Controllers Replacement Considerations

Direct replacements include the HS-3282 for basic dual-channel applications, though it lacks the multi-channel capacity. For higher integration, consider newer FPGA-based solutions from Microchip or other vendors. Verify pinout and register compatibility before substituting with similar ARINC controllers.
