A54SX08A-TQ144A

Overview

The A54SX08A-TQ144A is an automotive-grade Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 12,000 system gates and 768 combinatorial cells. The device operates within a temperature range of -40°C to 125°C and supports internal clock frequencies up to 250 MHz. It utilizes a 0.22µ CMOS process technology and includes two global routed clocks (CLKA, CLKB) and one hardwired clock (HCLK). The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and provides up to 113 user-programmable I/O pins.

Feature Summary

• Automotive-grade reliability with extended temperature support (-40°C to 125°C)
• Nonvolatile antifuse architecture providing deterministic timing and high security
• Hot-swap compliant I/Os allowing safe insertion without power sequencing
• Integrated boundary scan testing compliant with IEEE 1149.1 (JTAG)

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive logic integration replacing CPLDs

Procurement Notes

Verify that the specific ordering suffix corresponds to the TQFP-144 package type. Confirm the 'A' designation indicates the automotive temperature grade (-40°C to 125°C). Ensure the lead-free packaging status matches project requirements, as indicated by the 'G' suffix if present. Cross-reference the part number against the official Microchip/Actel SX-A Automotive Family datasheet for current availability and specification updates.

Selection Notes

Select this device when designing for automotive environments requiring operation at elevated temperatures. The SX-A architecture offers high logic density relative to its gate count, suitable for complex state machines and datapath logic. Consider the available routing resources and clock networks if high-speed synchronous designs are required. Verify that the 113 available user I/Os meet the interface requirements of the target application.

Part Context

This component belongs to the Actel SX-A FPGA family, which was acquired by Microchip Technology. The SX-A series is characterized by its sea-of-modules architecture and nonvolatile antifuse technology. The A54SX08A represents the entry-level capacity within the automotive-grade subset of this family, offering 12,000 system gates. It shares architectural similarities with commercial and industrial grades but is specifically qualified for automotive thermal conditions.

Replacement Considerations

Direct pin-compatible replacements within the same package include other devices from the SX-A family such as the A54SX16A or A54SX32A, provided the logic capacity requirements are met. Note that speed grades and temperature grades may vary across the family; verify electrical specifications before substitution.
