EX64-TQ100A

Field Programmable Gate Array Overview

The EX64-TQ100A is a Field Programmable Gate Array from the eX Automotive Family, manufactured by Microsemi Corporation. It utilizes advanced 0.22µm CMOS antifuse technology to deliver high performance with low power consumption. The device features 64 system gates and operates with mixed-voltage I/O support for 2.5 V, 3.3 V, and 5.0 V levels, including 5.0 V input tolerance. It is housed in a TQFP-100 package with 100 terminals. Key electrical specifications include a maximum clock frequency of 80 MHz and an operating temperature range extending up to 125 °C, suitable for automotive environments.

Field Programmable Gate Array Feature Summary

• Nonvolatile antifuse architecture enabling live-on-power-up operation without configuration sequences
• Automotive-grade reliability with extended temperature range support up to 125 °C
• Mixed-voltage I/O capability supporting 2.5 V, 3.3 V, and 5.0 V standards with 5.0 V drive strength

Field Programmable Gate Array Applications

• Automotive electronic control units requiring nonvolatile logic
• Power-sensitive embedded systems utilizing low static power modes
• Industrial interfaces requiring hot-swap compliant I/Os

Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized Microsemi distributors or certified suppliers. Confirm the specific suffix indicates the TQFP-100 package variant. Ensure compliance with automotive quality standards if required for the target application. Request full datasheets to validate manufacturing origin and revision history before integration into production designs.

Field Programmable Gate Array Selection Notes

Select this model when nonvolatile configuration is mandatory to eliminate external memory components. The 0.22µm process offers deterministic timing suitable for precise interface control. Consider the 100-pin count for moderate I/O density requirements. Evaluate thermal management needs given the 125 °C maximum junction temperature rating in enclosed automotive enclosures.

Field Programmable Gate Array Part Context

This component belongs to the eX (EX) family of FPGAs, designed specifically for cost-effective, low-power applications. Unlike flash-based FPGAs, it uses antifuse technology which provides permanent configuration. This family bridges the gap between discrete logic and complex programmable devices, offering flexibility with the security of nonvolatile storage.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same eX family include the EX128-PTQG100A for higher gate counts. Cross-family migration to Microsemi ProASIC3 or SmartFusion may require schematic redesign due to differing configuration architectures and voltage domains.
