A54SX16-TQG176I

The A54SX16-TQG176I is a nonvolatile SX family Field Programmable Gate Array (FPGA) from Microchip Technology designed for industrial applications. It delivers a compact, single‑chip programmable logic solution ideal for control, interface and glue‑logic tasks that require deterministic timing and mixed‑voltage I/O support.

With 24,000 system gates and 1,452 logic elements, this device targets designs that need a mid‑density FPGA in a 176‑pin thin quad flat package, supported across a 3.0 V to 5.5 V supply range and an industrial temperature rating.

Key Features

• Core Performance — Family-level performance includes up to 250 MHz system performance and up to 350 MHz internal performance for timing‑sensitive logic implementations.
• Resources — 24,000 system gates and 1,452 logic elements with 147 user I/Os; device reports 0 bits of on‑chip RAM.
• Configurable I/O & Mixed-Voltage Operation — Supports configurable I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; devices support 2.5 V, 3.3 V and 5 V mixed‑voltage operation with 5 V input tolerance and 5 V drive strength.
• Power and Reliability — Hot‑swap compliant I/Os and power‑up/power‑down friendly operation (no sequencing required for supply voltages) simplify system power management.
• Security and Test — Actel Secure Programming Technology with FuseLock™ protects design IP; boundary‑scan testing compliant with IEEE 1149.1 (JTAG) facilitates board‑level test.
• Deterministic Timing & Diagnostics — Deterministic, user‑controllable timing and unique in‑system diagnostic/verification capability with Silicon Explorer II provide predictable, debug‑friendly behavior.
• Package & Temperature — Available in a 176‑pin LQFP/TQFP package (supplier package 176‑TQFP, 24 × 24 mm) with an industrial operating temperature range of –40 °C to 85 °C.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Implement motor control timing, I/O aggregation, and deterministic control logic within industrial automation equipment operating across standard industrial temperature ranges.
• Interface Bridging — Bridge between mixed‑voltage buses and legacy 3.3 V/5 V signal domains for protocol conversion and glue logic.
• Embedded Systems — Provide mid‑density programmable logic for system control, peripheral management, and custom logic functions where nonvolatile single‑chip configuration is required.
• Test & Measurement — Use in test fixtures and instrumentation that benefit from in‑system diagnostics and boundary‑scan testability for board‑level validation.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates the need for external configuration memory and simplifies system boot behavior.
• Mixed‑Voltage Flexibility: Broad I/O standard support and 5 V tolerance allow easy integration with legacy and modern logic families, reducing interface translation hardware.
• Industrial Temperature Rating: Rated for –40 °C to 85 °C, suitable for a wide range of industrial environments.
• Security and Testability: FuseLock™ secure programming and IEEE 1149.1 boundary‑scan support streamline production test and protect intellectual property.
• Deterministic Timing & Diagnostics: User‑controllable timing plus in‑system diagnostic tools support predictable system behavior and faster debug cycles.
• Compact Packaging: 176‑pin TQFP/LQFP footprint provides a balance of I/O density and PCB area efficiency for mid‑range designs.
