A54SX32-2TQ144

Overview

The A54SX32-2TQ144 is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 48,000 system gates and supports up to 113 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. The device operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect
• Includes IEEE 1149.1 compliant Boundary-Scan Testing for diagnostic and verification capabilities
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• Low-power, high-performance designs requiring nonvolatile integration
• Applications needing mixed-voltage I/O support for 3.3V/5V PCI, 5V TTL, or 2.5V LVCMOS2

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to approximately 25% faster performance than standard speed when sourcing this component. Confirm the temperature grade suffix matches the required operating environment, as blank indicates commercial range. Ensure the ordering suffix aligns with the desired packaging type and lead-free compliance status defined in the official datasheet.

Selection Notes

Select the A54SX32-2TQ144 when 48,000 system gates and 113 I/Os are required in a TQFP-144 package. The '-2' speed grade offers higher performance than the standard grade. Consider the SX-A architecture's antifuse nature for permanent configuration needs. Verify that the 250 MHz system performance meets the design's timing constraints compared to other speed grades.

Part Context

This part belongs to the Actel SX-A FPGA family, which uses antifuse technology for nonvolatile configuration. The SX-A series provides a single-chip solution integrating CPLD and FPGA capabilities. The A54SX32 variant specifically offers 48,000 system gates, positioning it between the A54SX16A and A54SX72A in terms of capacity within the product line.
