A54SX32A-TQG144

The A54SX32A-TQG144 is a member of the SX‑A family of nonvolatile, single‑chip FPGAs from Microchip Technology. This commercial‑grade device delivers 48,000 system gates implemented as approximately 2,880 logic elements with 113 user I/Os in a 144‑pin thin quad flat pack (TQFP/LQFP) package.

Designed for mixed‑voltage systems, the device supports a wide supply range (2.25 V to 5.25 V) and operates over a commercial temperature range (0 °C to 70 °C). It targets embedded logic, interface bridging and I/O‑centric applications that benefit from nonvolatile configuration, flexible I/O and deterministic timing.

Key Features

• Logic Capacity — Approximately 48,000 system gates and 2,880 logic elements provide substantial combinational and sequential logic resources for moderate‑complexity designs.
• User I/O — 113 user‑programmable I/O pins in a 144‑pin package; configurable I/O support for multiple voltage standards and mixed‑voltage operation.
• Performance — Family data indicates up to 250 MHz system performance and up to 350 MHz internal performance for timing‑critical paths.
• Nonvolatile Single‑Chip Architecture — Single‑chip, nonvolatile configuration removes the need for external configuration memory and simplifies system design.
• Flexible I/O and Voltage Support — Configurable I/O support for 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.
• Hot‑Swap and Power‑Friendly I/Os — Hot‑swap compliant I/Os and power‑up/power‑down friendly operation (no supply sequencing required) simplify integration into live‑insertion and multi‑rail systems.
• PCI and Boundary‑Scan Support — 66 MHz PCI compliance and IEEE 1149.1 JTAG boundary‑scan support for board‑level testing and system integration.
• Device Security and Diagnostics — Family features include Actel Secure Programming Technology (FuseLock™) and in‑system diagnostic/verification capability (Silicon Explorer II) for design protection and validation.
• Packaging and Environmental — 144‑pin thin QFP package (20 × 20 mm footprint) and RoHS‑compliant material listing.
• Commercial Temperature Grade — Rated for operation from 0 °C to 70 °C for standard commercial applications.

Typical Applications

• PCI Bus Interfaces — Implement PCI‑compliant endpoints, bridges or peripheral logic leveraging the device's 66 MHz PCI support and flexible I/O voltages.
• Mixed‑Voltage System Glue Logic — Interface and translate between 5 V and lower‑voltage domains using the device's mixed‑voltage I/O and 5 V input tolerance.
• Embedded Control and Peripheral Offload — Use nonvolatile single‑chip configuration to provide persistent logic for control, protocol offload or custom I/O handling without external configuration memory.

Unique Advantages

• Nonvolatile, Single‑Chip Solution: Eliminates external configuration components and simplifies board design and supply chain.
• Wide Supply Range: 2.25 V to 5.25 V support enables deployment across a variety of systems and simplifies integration with different power domains.
• Deterministic Timing and High Utilization: Family capability for deterministic, user‑controllable timing and up to 100% resource utilization helps achieve predictable system behavior.
• Robust I/O Flexibility: Configurable I/O standards, 5 V tolerance and individual output slew control allow precise interface tuning and reliable signaling across domains.
• Built‑In Security and Testability: FuseLock programming and IEEE‑1149.1 boundary‑scan support protect IP and streamline board‑level testing and diagnostics.
