A54SX32-1BG329I

Overview

The A54SX32-1BG329I is an SX-A series Field Programmable Gate Array (FPGA) manufactured by Microchip Technology. It provides 48,000 system gates and supports up to 249 user-programmable I/O pins within a 329-pin Plastic Ball Grid Array (PBGA) package. The device operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The industrial temperature grade (-40°C to +85°C) is indicated by the 'I' suffix.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into electrically active systems without degrading host reliability or requiring specific power sequencing.
• Supports 66 MHz PCI compliance and configurable I/O standards including 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Includes Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for diagnostic and verification capabilities.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays in industrial control systems.
• PCI-compliant interface designs requiring deterministic timing and hot-swap capability.
• Secure embedded applications utilizing FuseLock technology to prevent reverse engineering and design theft.

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status as packaging options vary. Check for end-of-life notifications or production change notices (PCN) relevant to this specific part number before procurement planning.

Selection Notes

Select the A54SX32-1BG329I when 48,000 system gates and 249 I/Os are required in a PBGA-329 package. The '-1' speed grade offers approximately 15% faster performance than standard speed. Ensure the design accommodates the industrial temperature range (-40°C to +85°C) specified by the 'I' suffix.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their nonvolatile antifuse technology. The SX-A series is designed for low-power, high-performance applications, offering a cost-effective alternative to volatile FPGA solutions that require external configuration memory.
