A54SX32A-2TQG100

The A54SX32A-2TQG100 is a commercial-grade SX-A family FPGA in a 100-pin TQFP surface-mount package. It delivers a nonvolatile, single-chip FPGA architecture with deterministic timing and support for mixed-voltage I/O, making it suitable for embedded control and mixed-signal interface applications.

Built around 48,000 system gates and 2,880 logic elements, this device provides a balance of gate density and I/O count (81 user I/Os) for designs that require secure, in-field programmable logic with flexible I/O standards and broad supply-voltage tolerance.

Key Features

• Core Performance — System performance up to 250 MHz and internal performance up to 350 MHz as documented for the SX-A family; deterministic, user-controllable timing for repeatable timing closure.
• Logic Capacity — Approximately 48,000 system gates and 2,880 logic elements suitable for mid-density logic integration.
• I/O and Voltage Flexibility — 81 user-programmable I/O pins with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2. Device supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and 5 V drive strength.
• Package and Mounting — Available in a 100-TQFP (14×14 mm) thin quad flat pack, surface-mount mounting for compact board-level integration.
• Power-Up/Down Friendly — Power-up/power-down friendly design that does not require supply-voltage sequencing.
• Hot-Swap and I/O Control — Hot-swap compliant I/Os with configurable weak pull-up or pull-down on power-up and individual output slew-rate control.
• Security and Test — Actel Secure Programming Technology with FuseLock to guard design IP, plus boundary-scan testing in compliance with IEEE 1149.1 (JTAG) for in-system testability.
• Diagnostics and Development — Supports in-system diagnostic and verification capability with Silicon Explorer II for debug and validation workflows.
• Operating Range — Commercial temperature grade with an operating range of 0°C to 70°C and supply-voltage support from 2.25 V to 5.25 V.
• Environmental Compliance — RoHS-compliant manufacturing.

Typical Applications

• PCI and Legacy Interface Designs — Use the device’s 66 MHz PCI compliance and multi-voltage I/O support to implement PCI or mixed-voltage interface logic and bridging functions.
• Embedded Control and Glue Logic — Integrate mid-density combinational and sequential logic in compact systems where nonvolatile, single-chip programmability and predictable timing are required.
• Secure, Field-Programmable Systems — Leverage FuseLock secure programming and in-system verification for applications that require IP protection and in-field updates.
• Board-Level Test and Validation — Employ JTAG boundary-scan and Silicon Explorer II diagnostics for production test, board bring-up, and system validation.

Unique Advantages

• Nonvolatile, Single-Chip FPGA: Eliminates external configuration memory and simplifies system power-up behavior and board-level BOM.
• Wide Supply Range: 2.25 V to 5.25 V supply support and mixed-voltage I/O capability reduce the need for level translators in multi-supply designs.
• IP Protection Built-In: FuseLock secure programming protects device bitstreams against reverse engineering and helps preserve design investment.
• Deterministic Timing: User-controllable timing characteristics make the device suitable for applications where predictable, repeatable timing is required.
• Compact Packaging: 100-pin TQFP surface-mount package provides a small footprint option for space-constrained PCBs while offering a substantial I/O count.
• Test and Debug Support: On-board boundary-scan (IEEE 1149.1) and in-system diagnostic support streamline manufacturing test and field diagnostics.
