A54SX08A-1TQ144

Overview

The A54SX08A-1TQ144 is a Field Programmable Gate Array from the Microchip SX-A family, utilizing antifuse technology. It features 12,000 system gates and 768 logic modules. The device provides 113 user-programmable I/Os in a 144-pin Thin Quad Flat Pack (TQFP) package. It supports mixed-voltage operation at 2.5 V, 3.3 V, and 5.0 V with 5.0 V input tolerance. The speed grade -1 indicates approximately 15% faster performance than standard, achieving up to 250 MHz system performance. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities for most I/O standards, allowing safe insertion into active systems without power sequencing requirements.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing for superior diagnostic and verification capabilities.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• Low-power, high-performance designs requiring single-chip integration
• Systems requiring nonvolatile configuration without external bitstream memory
• Applications needing mixed-voltage I/O interfacing (2.5V, 3.3V, 5V)
• Industrial environments requiring extended temperature range operation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options may vary. Check for end-of-life notifications or discontinuance notices from Microchip Technology prior to finalizing procurement plans.

Selection Notes

Select this component when 12,000 system gates and 113 I/Os are sufficient for the design. The -1 speed grade offers higher performance than the standard grade. Ensure the TQFP-144 package fits the PCB footprint constraints. Verify that the industrial temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the SX-A family of FPGAs, which are built on 0.22 μm / 0.25 μm CMOS antifuse technology. The family includes devices ranging from 8,000 to 108,000 system gates. The A54SX08A variant represents the entry-level capacity within this specific series, offering a balance of logic density and pin count for compact applications.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX08A series, such as the standard speed grade A54SX08A-TQ144 or the slower -F grade A54SX08A-F-TQ144. Upgrades in capacity within the same package require moving to the A54SX16A-TQ144. Cross-family migration to SmartFusion or IGLOO requires significant redesign.

FAQ

What is the maximum system performance frequency for the A54SX08A-1TQ144?

The SX-A family devices support up to 250 MHz system performance. The internal clock frequencies can reach up to 350 MHz.

Does the A54SX08A-1TQ144 support hot-swapping?

Yes, the I/Os are configured to be hot-swappable, with the exception of 3.3 V PCI. During power-up/down, all I/Os are tristated, preventing damage to the host system.

How many global clocks are available on the A54SX08A?

The A54SX08A device provides three global clocks: one hardwired clock (HCLK) and two routed global clocks (CLKA and CLKB). It does not have quadrant clocks.
