TS68C429AVF1

Controllers Overview

The TS68C429AVF1 is an ARINC 429 controller manufactured by Microchip Technology, designed for high-performance multi-channel receiver and transmitter applications. It features eight independent ARINC receiver channels and three independent transmitter channels, supporting data rates up to 2.5 Mbit/s with programmable frequency settings. The device operates at a maximum clock frequency of 20 MHz and includes an 8-message FIFO per transmitter channel. It provides full compatibility with the TS68K family microprocessor interface via a 16-bit data bus and supports vectored interrupts with daisy-chain capability. The component is housed in a CQFP-132 package and complies with MIL-STD-883 Class B screening standards.

Controllers Feature Summary

• Supports ARINC 429 protocol with independent programmable frequencies for each channel
• Includes self-test capabilities for receiver label memories and transmit FIFOs
• Features parity control with interrupt capability for odd, even, or no parity configurations
• Provides direct addressing of all registers and comprehensive interrupt management

Controllers Applications

• Avionics systems requiring ARINC 429 data bus communication
• Military aerospace electronic equipment adhering to MIL-STD-883 standards
• Embedded flight control computers interfacing with TS68K processors

Controllers Procurement Notes

Verify the specific suffix 'V' indicates the commercial temperature range (-40°C to +85°C) rather than the military grade 'M' variant (-55°C to +125°C). Confirm the 'F' suffix corresponds to the CQFP-132 ceramic package. Ensure procurement sources provide documentation confirming compliance with DESC Drawing 5962-955180 and MIL-STD-883 Class B requirements for critical deployments.

Controllers Selection Notes

Select this component when designing systems requiring multiple simultaneous ARINC 429 channels with hardware-managed FIFO buffering. It is suitable for environments where low power consumption (400 mW max) and high reliability are prioritized. Consider the 16-bit processor interface compatibility when integrating with legacy or specialized microcontrollers like the Atmel TS68K family.

Controllers Part Context

The TS68C429A serves as an enhanced version of the EF 4442, specifically optimized for connection to 16- or 32-bit microprocessors. It functions as a Multi-Channel Receiver/Transmitter (MRT), bridging the gap between host processors and ARINC 429 avionics buses. The device integrates logical control, interrupt management, and dedicated receiver/transmitter units into a single CMOS chip.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout and register compatibility if considering alternative ARINC controllers from other manufacturers.
