A54SX72A-2FG256I

The A54SX72A-2FG256I is an SX-A family FPGA from Microchip Technology offering a nonvolatile, single-chip programmable solution for industrial designs. It combines a high-capacity logic fabric with a large I/O count and mixed-voltage I/O support to address glue-logic, protocol bridging and control applications that require deterministic timing and in-system diagnostics.

Key value propositions include 108,000 system gates of capacity implemented as 6,036 logic elements, up to 203 user I/Os in a 256-pin FBGA package, and industrial temperature operation for robust deployed systems.

Key Features

• Core capacity and performance — 108,000 system gates implemented as 6,036 logic elements; family-level performance figures include up to 250 MHz system performance and up to 350 MHz internal performance as documented for the SX-A family.
• Logic and flip-flops — Supports up to 2,012 dedicated flip-flops (family specification) enabling register-rich designs and synchronous implementations.
• I/O flexibility — 203 user-programmable I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 levels, hot-swap compliant I/Os, and 5 V input tolerance and 5 V drive strength (family features).
• Memory — No on-chip RAM (Total RAM bits: 0) as provided in the product data.
• Power and sequencing — Operates from a 2.25 V to 5.25 V supply range and is power-up/power-down friendly with no sequencing required for supply voltages (family feature).
• Package and mounting — 256-BGA package (supplier package: 256-FPBGA, 17×17 mm), surface-mount mounting suitable for compact, board-level integration.
• Industrial temperature grade — Rated for operation from −40 °C to +85 °C.
• Security and test — Supports boundary-scan testing in compliance with IEEE 1149.1 (JTAG) and includes Actel Secure Programming Technology with FuseLock for design protection; also offers in-system diagnostics and verification capability with Silicon Explorer II (family features).
• Deterministic timing — Deterministic, user-controllable timing for predictable system behavior (family feature).
• Standards and compatibility — 66 MHz PCI compliant (family feature), enabling use in PCI-based subsystems where applicable.
• RoHS status — RoHS compliant.

Typical Applications

• Industrial control and automation — Industrial temperature rating (−40 °C to +85 °C) and a broad supply range (2.25 V–5.25 V) make this FPGA suitable for control logic, motor drives and factory automation interfaces.
• Protocol bridging and interface logic — High I/O count (203 I/Os) and configurable multi-voltage I/O support enable protocol translation, bus bridging and custom peripheral interfacing.
• PCI-based subsystems — 66 MHz PCI compliance and deterministic timing support implementation of PCI glue logic and interface controllers within larger systems.
• Secure and verifiable systems — Built-in secure programming (FuseLock) and JTAG boundary-scan support are suited to applications that require IP protection and in-system testability.

Unique Advantages

• High-capacity programmable fabric: 108,000 system gates and 6,036 logic elements deliver substantial logic resources for complex glue logic and custom functions without adding discrete ASICs.
• Large, flexible I/O: 203 user I/Os with mixed-voltage support reduce the need for level shifters and simplify board-level interfacing to diverse peripherals and buses.
• Nonvolatile single-chip solution: On-chip nonvolatile configuration removes the requirement for external configuration memory and simplifies system design.
• Industrial robustness: Surface-mount 256-FPBGA package plus industrial temperature rating supports deployment in harsh environments.
• Security and testability: FuseLock secure programming and IEEE 1149.1 boundary-scan deliver IP protection and standardized manufacturing/test support.
• Predictable timing behavior: Deterministic, user-controllable timing helps achieve consistent system-level performance and simplifies timing closure.
