A54SX32A-2TQ144

Overview

The A54SX32A-2TQ144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 249 user-programmable I/O pins. The device operates with internal clock frequencies reaching 350 MHz and delivers 250 MHz system performance. It features three global clock networks (HCLK, CLKA, CLKB) and includes boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG). The component utilizes nonvolatile single-chip architecture for secure programming.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Includes deterministic timing control with individual output slew rate selection.
• Provides 100% resource utilization capability with full pin-locking support.

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to approximately 25% faster performance than standard speed. Confirm the temperature grade suffix matches the required operating range, as blank indicates commercial (0 to +70°C), 'I' indicates industrial (-40 to +85°C), 'A' indicates automotive (-40 to +125°C), and 'M' indicates military (-55 to +125°C). Ensure the package type TQFP-144 aligns with board layout constraints.

Selection Notes

Select this device when 48,000 system gates are required within a 144-pin Thin Quad Flat Pack. Consider the -2 speed grade if higher frequency performance is needed compared to the standard grade. Verify that the application requires nonvolatile configuration to eliminate external configuration memory. Check if the specific temperature grade suffix is necessary for the environmental conditions.
