A54SX08A-1TQG144

The A54SX08A-1TQG144 is a nonvolatile SX-A family FPGA from Microchip Technology providing 12,000 system gates in a compact 144-pin surface-mount package. It combines programmable logic with configurable I/O and deterministic timing capabilities for embedded applications that require in-system reconfiguration and secure programming.

With 768 logic elements and up to 113 user I/Os, the device targets designs that need moderate logic capacity, mixed-voltage I/O support, and single-chip nonvolatile configuration in a commercial temperature grade (0°C to 70°C).

Key Features

• Logic Capacity: 12,000 system gates with 768 logic elements, suitable for moderate-complexity programmable logic implementations.
• User I/O: 113 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 signaling.
• Performance: Documented system performance up to 250 MHz and internal performance up to 350 MHz, supporting responsive logic and interface tasks.
• Nonvolatile Single-Chip Configuration: On-chip nonvolatile configuration removes the need for external configuration memory and enables single-chip deployment.
• Voltage and Power: Wide supply range from 2.25 V to 5.25 V and power-up/power-down friendly operation with no required sequencing of supply voltages.
• Package and Mounting: 144-pin LQFP surface-mount package (supplier device package 144-TQFP, 20×20) for compact board-level integration.
• Commercial Temperature Grade: Rated for 0°C to 70°C operation for standard commercial applications.
• On-Chip Memory: No embedded RAM (0 bits), useful to know when planning external memory requirements.
• System and Testability: Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability.
• Security: Secure programming technology (FuseLock) to protect designs from reverse engineering.
• Standards & Interfaces: 66 MHz PCI compliance and hot-swap compliant I/Os to support common peripheral and interface use cases.
• RoHS Compliance: Device is RoHS compliant.

Typical Applications

• Interface and Glue Logic: Use the A54SX08A-1TQG144 to implement bus bridging, protocol translation, and board-level interface logic where mixed-voltage I/O and 113 programmable pins are required.
• Peripheral Control and I/O Management: Suitable for managing peripherals, I/O expansion, and control tasks that benefit from nonvolatile configuration and deterministic timing.
• Embedded System Logic: Deploy as on-board programmable logic for embedded controllers that require a single-chip, nonvolatile FPGA solution in a compact package.

Unique Advantages

• Nonvolatile, single-chip configuration: Eliminates external configuration memory, simplifying BOM and system initialization.
• Configurable mixed-voltage I/O: Supports multiple I/O standards and 5 V input tolerance for flexible interfacing with legacy and modern logic levels.
• Secure programming: FuseLock-style secure programming protects intellectual property and prevents reverse engineering.
• Deterministic timing and diagnostics: Deterministic, user-controllable timing and in-system diagnostic capability help streamline bring-up and verification.
• Compact surface-mount package: 144-pin LQFP offers a space-efficient footprint for board-level integration while providing a substantial I/O count.
• Power-up/down friendly: No supply sequencing required, reducing system-level power management complexity.
