A54SX16A-1TQ144I

The A54SX16A-1TQ144I is an industrial-grade SX-A family FPGA from Microchip Technology. It provides a nonvolatile, single-chip programmable logic solution with 24,000 system gates and 1,452 logic elements for implementing control, interface, and glue-logic functions in embedded and industrial systems.

With 113 user I/Os in the 144-pin LQFP/TQFP footprint, wide supply range (2.25 V to 5.25 V) and an operating temperature of −40 °C to 85 °C, this device is targeted at mixed-voltage, industrial and general embedded applications that require deterministic timing, configurable I/O and in-system programmability.

Key Features

• Core Capacity — 24,000 system gates and 1,452 logic elements provide a compact, programmable fabric for control and interface logic.
• User I/O — 113 user-programmable I/O pins in the 144-pin package, with configurable I/O options for mixed-voltage operation.
• Voltage Flexibility — 2.25 V to 5.25 V supply range supports 2.5 V, 3.3 V and 5 V signaling scenarios as documented for the SX-A family.
• Performance (Series) — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as specified in the series datasheet.
• Configuration and Security — Nonvolatile, single-chip configuration; series-level security features include Actel Secure Programming Technology with FuseLock™ to help protect designs against reverse engineering.
• System Integration — Series-level features include hot-swap compliant I/Os, power-up/power-down friendly operation with no sequencing required for supply voltages, and IEEE 1149.1 (JTAG) boundary-scan testing.
• Package and Mounting — 144-pin LQFP package (supplier device package listed as 144-TQFP, 20×20); surface-mount mounting type for compact PCB designs.
• Industrial Temperature Grade — Rated for −40 °C to 85 °C operation.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Implement deterministic control logic, interface adaptation and timing-critical glue logic for automation and factory equipment.
• Embedded System Glue Logic — Bridge mixed-voltage peripherals, implement protocol adapters or customize I/O timing within space-constrained PCBs using the 144-pin package.
• PCI and Bus Interfaces — Use the SX-A family’s documented 66 MHz PCI compliance and configurable I/O support for 3.3 V/5 V PCI and other bus-level interfacing (series-level capability).
• Instrumentation and Test — Boundary-scan (IEEE 1149.1) support and in-system diagnostic capabilities from the SX-A series help streamline board-level test and verification flows.

Unique Advantages

• Compact, Programmable Integration: 24,000 system gates and 1,452 logic elements reduce external glue logic and simplify PCB designs.
• Mixed-Voltage Support: Wide supply range and series-configurable I/O enable direct interfacing to 2.5 V, 3.3 V and 5 V domains, minimizing level-shifting components.
• Nonvolatile Single-Chip Solution: Eliminates the need for external configuration memory, simplifying power-up behavior and board-level BOM.
• Design Protection: FuseLock™ security in the SX-A series helps protect intellectual property on-device.
• Industrial Reliability: Industrial temperature rating (−40 °C to 85 °C) and surface-mount 144-pin package support robust deployment in industrial environments.
• Testability and Diagnostics: IEEE 1149.1 (JTAG) boundary-scan and series in-system diagnostic features improve board-level test and field diagnostics.
