A54SX32A-2FG256I

The A54SX32A-2FG256I is a member of the SX-A family of nonvolatile, single-chip FPGAs from Microchip Technology. It delivers deterministic FPGA resources with 48,000 system gates and 2,880 logic elements in a 256-pin fine‑pitch BGA package, suited for industrial-temperature applications.

Designed for mixed‑voltage systems, the device supports a wide supply range and dense I/O, making it appropriate for industrial control, mixed‑voltage interface designs, and embedded logic functions that benefit from nonvolatile configuration and in-system diagnostics.

Key Features

• Core Performance — Typical system performance up to 250 MHz and internal performance up to 350 MHz as published for the SX-A family; device is marked with the –2 speed grade (approximately 25% faster than standard).
• Logic Capacity — 48,000 system gates and 2,880 logic elements with up to 2,012 dedicated flip‑flops available for register-rich designs.
• I/O and Interface — 203 user I/O pins in a 256‑ball FBGA package; configurable I/O supports 2.5 V, 3.3 V and 5 V signaling modes and mixed‑voltage operation with 5 V input tolerance and 5 V drive strength.
• Power and Voltage — Wide supply range: 2.25 V to 5.25 V; power‑up/down friendly with no sequencing required for supply voltages.
• Package and Temperature — 256‑FPBGA (17×17) fine‑pitch BGA package (FG), industrial temperature grade (I) with operating range −40 °C to +85 °C.
• System Integration — Nonvolatile single‑chip solution that eliminates the need for external configuration memory; supports deterministic, user‑controllable timing.
• System Reliability & Test — Hot‑swap compliant I/Os, boundary‑scan (IEEE 1149.1) support, and in‑system diagnostic/verification capability with Silicon Explorer II.
• Security — Actel Secure Programming Technology with FuseLock™ to protect bitstream and prevent reverse engineering.

Typical Applications

• Industrial Control — Handles control logic, glue‑logic, and deterministic timing in factory automation and process control systems operating across industrial temperature ranges.
• Mixed‑Voltage Interface — Acts as an interface bridge or protocol translator for systems that require 2.5 V, 3.3 V and 5 V signaling with 5 V I/O tolerance.
• PCI and Peripheral Logic — Suitable for PCI‑compliant peripheral designs and board‑level interfaces that benefit from hot‑swap I/O behavior and nonvolatile configuration.
• Embedded System Glue Logic — Implements custom control, timing, and glue logic where nonvolatile single‑chip configuration and in‑system diagnostics simplify system design.

Unique Advantages

• Nonvolatile Single‑Chip Configuration: Eliminates external configuration memory and simplifies power‑up behavior, reducing BOM and system complexity.
• Wide Supply Flexibility: 2.25 V to 5.25 V supply range and mixed‑voltage I/O support enable straightforward integration with legacy and modern logic levels.
• Industrial Temperature Rating: Rated for −40 °C to +85 °C, making the device suitable for industrial deployment without additional temperature qualification.
• Dense I/O in a Compact FBGA: 203 user I/Os in a 256‑ball fine‑pitch BGA package provide a high I/O count for space‑constrained boards.
• Security and Testability: Built‑in FuseLock programming security plus boundary‑scan support and in‑system diagnostics accelerate development and protect IP.
• Deterministic Timing and Resource Utilization: Enables predictable timing closure and efficient use of available logic and flip‑flop resources for control‑centric designs.
