A54SX72A-1FG256

The A54SX72A-1FG256 is a nonvolatile SX-A family FPGA from Microchip Technology that integrates programmable logic and configurable I/O in a single 256‑ball fine‑pitch BGA package. With 108,000 system gates and 6,036 logic elements, it is intended for designs that require high gate density, flexible I/O support and deterministic timing in a commercially graded device.

This device supports mixed‑voltage operation and a broad supply range, making it suitable for embedded control, interface bridging and system consolidation where a nonvolatile single‑chip solution and in‑system diagnostics are important.

Key Features

• Logic Capacity – 108,000 system gates and 6,036 logic elements with up to 2,012 dedicated flip‑flops for complex logic implementation and register‑rich designs.
• Performance – SX‑A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as documented for the family.
• Configurable I/O – 203 user‑programmable I/Os on the 256‑BGA package, with configurable support for multiple I/O standards and 5 V tolerance as described in the SX‑A family documentation.
• Voltage and Power – Flexible supply operation from 2.25 V to 5.25 V, enabling mixed‑voltage system integration with power‑up/down friendly behavior (no supply sequencing required).
• Nonvolatile Single‑Chip Solution – Built as a nonvolatile FPGA family member, eliminating need for external configuration memory in deployed systems.
• Security and Test – Includes Actel Secure Programming Technology with FuseLock™ for anti‑reverse engineering protection and supports IEEE 1149.1 (JTAG) boundary‑scan testing for board‑level diagnostics.
• In‑System Diagnostics – Family features include unique in‑system diagnostic and verification capabilities (Silicon Explorer II) to aid validation and field diagnostics.
• Package and Grade – 256‑FBGA (1.0 mm fine‑pitch BGA, 17×17 mm) in a commercial grade device with operating temperature range 0 °C to 70 °C.
• On‑Chip Memory – Total on‑chip RAM reported as 0 bits; this device targets logic‑centric implementations rather than embedded RAM applications.

Typical Applications

• Interface Bridging – Use the configurable I/O and mixed‑voltage support to implement protocol bridging and level translation between subsystems.
• Embedded Control – Consolidate control logic and state machines within the FPGA’s 6,036 logic elements and flip‑flop resources for compact embedded designs.
• PCI‑Capable Systems – SX‑A family documentation includes PCI‑compliant I/O support for 66 MHz PCI applications where a nonvolatile FPGA is required.
• Board Test and Diagnostics – Leverage boundary‑scan (IEEE 1149.1) and in‑system diagnostic features to streamline board‑level test, verification and field diagnostics.

Unique Advantages

• Highly integrated, nonvolatile solution: Single‑chip nonvolatile FPGA removes the need for external configuration memory and simplifies power‑up behavior.
• Flexible I/O and mixed‑voltage operation: 203 configurable I/Os and a wide supply voltage range allow integration with a variety of system I/O standards without extra level‑shifters.
• Deterministic timing and performance: Family performance characteristics and deterministic timing controls support predictable system timing and high‑speed internal paths.
• Security‑oriented programming: FuseLock™ secure programming technology offers protection against reverse engineering and unauthorized access to bitstream contents.
• Built‑in testability: IEEE 1149.1 boundary‑scan and in‑system diagnostics simplify production test and in‑field verification workflows.
• Compact, high‑density packaging: 256‑FBGA fine‑pitch package provides a high I/O count and compact board footprint for space‑constrained designs.
