A54SX32A-TQG100I

The A54SX32A-TQG100I is an SX-A family FPGA offered in a 100-pin thin quad flat package (100‑LQFP / 100‑TQFP, 14×14). It provides a nonvolatile, single‑chip programmable logic solution with 48,000 system gates and 2,880 logic elements intended for industrial applications.

With 81 user I/Os, a wide 2.25 V to 5.25 V supply range and an industrial operating temperature rating of −40 °C to 85 °C, this device is suitable for embedded control, I/O bridging and mixed‑voltage interface designs where in‑system programmability, security and robust I/O behavior are required.

Key Features

• Core & capacity — 48,000 system gates and 2,880 logic elements provide mid‑range programmable logic capacity for control, glue logic and protocol handling.
• User I/O — 81 user‑programmable I/Os with configurable input/output standards; supports mixed‑voltage operation to interface with a variety of device levels.
• Voltage flexibility — Operates across a wide supply range (2.25 V to 5.25 V), enabling integration into systems with diverse power rails.
• Package & mounting — Surface mount 100‑LQFP (supplier package: 100‑TQFP, 14×14) for compact PCB footprints and standard SMT assembly.
• Industrial temperature grade — Specified for −40 °C to 85 °C operation to meet industrial environmental requirements.
• Nonvolatile single‑chip configuration — SX‑A family characteristic: nonvolatile configuration that removes the need for external configuration memory and supports power‑up/power‑down friendly operation.
• System performance (SX‑A family) — Family datasheet lists up to ~250 MHz system performance and up to ~350 MHz internal performance for time‑critical logic (refer to SX‑A family documentation for details).
• Reliability & test — Includes IEEE‑1149.1 boundary‑scan (JTAG) support and features for hot‑swap compliant I/Os and configurable weak pull‑ups/pull‑downs for predictable behavior at power‑up.
• Security — Family includes Actel Secure Programming Technology (FuseLock) for design protection and anti‑reverse engineering capability.
• Environmental compliance — RoHS compliant.

Typical Applications

• Industrial control and automation — Implement custom control logic and I/O interfacing in industrial equipment using the device’s industrial temperature rating and wide supply range.
• Mixed‑voltage interface bridging — Use the configurable I/Os and 2.25 V–5.25 V support to adapt between differing logic levels and peripheral domains on a single board.
• PCI and legacy interface boards — SX‑A family support for 66 MHz PCI and multiple I/O standards makes the device suitable for PCI peripheral glue logic and protocol adaptation (refer to family datasheet for PCI compliance details).
• Embedded system glue logic — Mid‑density logic capacity and 81 I/Os enable consolidation of discrete glue logic, device control and small peripheral management into one programmable device.

Unique Advantages

• Single‑chip nonvolatile configuration: Eliminates external configuration memory, simplifying BOM and board layout.
• Wide supply and mixed‑voltage I/O: 2.25 V–5.25 V supply range and configurable I/O standards reduce the need for level shifters and simplify power design.
• Industrial temperature support: Rated for −40 °C to 85 °C to meet environmental demands of industrial deployments.
• Security features: Built‑in FuseLock programming technology helps protect intellectual property and prevent reverse engineering.
• Diagnostic and test support: Boundary‑scan (JTAG) and family diagnostic capabilities aid board‑level test and in‑system verification.
• Compact SMT package: 100‑pin thin QFP provides a balance of I/O count and PCB area for space‑constrained designs.
