A54SX72A-PQ208

Overview

The A54SX72A-PQ208 is a nonvolatile Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 360 user-programmable I/O pins and includes three global clocks plus four quadrant clocks. Operating voltage ranges from 2.25V to 5.25V, with an industrial temperature grade (-40°C to +85°C). It utilizes 0.22μ/0.25μ CMOS antifuse technology for permanent configuration.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports mixed-voltage operation with 5V input tolerance and drive strength across 2.5V, 3.3V, and 5V I/O standards.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes IEEE 1149.1 (JTAG) boundary-scan testing and Actel FuseLock security technology to prevent reverse engineering.

Applications

• High-performance digital signal processing and control applications requiring deterministic timing.
• Systems requiring hot-swappable capabilities or cold-sparing redundancy.
• Complex logic integration replacing multiple CPLDs or gate arrays in telecommunications and industrial equipment.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) as defined in the datasheet. Confirm the 'PQ' package designation corresponds to the 208-pin Plastic Quad Flat Pack. Ensure compliance with RoHS packaging requirements if applicable to the specific revision. Check for any discontinued status updates regarding speed grades or package availability through official Microchip channels.

Selection Notes

Select this device when high gate density (108,000 system gates) and low-power operation are required in a surface-mount PQFP package. Consider the SX-A architecture's unique DirectConnect and FastConnect routing for predictable timing in complex state machines. Verify that the 208-pin count accommodates all necessary I/O signals, noting the maximum of 360 user-programmable pins available on the A54SX72A series.

Part Context

The A54SX72A belongs to the SX-A family of FPGAs, which offers leading-edge performance with internal clock frequencies up to 350 MHz. This family is characterized by its sea-of-modules architecture and patented antifuse technology. The A54SX72A represents the highest capacity variant in the standard SX-A lineup, providing extensive logic resources and advanced clocking structures including quadrant clocks.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX72A such as A54SX72A-1PQ208I or A54SX72A-2PQ208I. For lower capacity needs, the A54SX32A-PQ208I may be considered if resource utilization permits. Cross-family migration to RT or ProASIC3L requires schematic redesign due to architectural differences.
