A54SX16P-1VQ100

The A54SX16P-1VQ100 is a commercial-grade SX-A family FPGA from Microchip Technology in a 100-pin thin quad flat pack (TQFP) surface-mount package. It provides 24,000 system gates implemented as approximately 1,452 logic elements with 81 user I/Os, making it suitable for compact, reprogrammable digital logic, interface control, and system integration tasks in commercial embedded designs.

As a member of the SX-A family, this device benefits from single-chip nonvolatile configuration and a set of system features aimed at deterministic timing, in-system diagnostics, and flexible I/O voltage support.

Key Features

• Logic Capacity  Approximately 24,000 system gates implemented as 1,452 logic elements, enabling moderate-density logic integration in a compact package.
• User I/O  81 user-programmable I/O pins provided in the 100-TQFP package for signal interfacing and peripheral connections.
• Package & Mounting  100-pin TQFP (14 × 14 mm) surface-mount package (supplier device package 100-VQFP), optimized for compact board layouts.
• Voltage Support  Wide supply range from 3.0 V to 5.25 V; SX-A family supports mixed-voltage operation including 2.5 V, 3.3 V and 5 V I/O levels with 5 V input tolerance and 5 V drive strength (family-level capability).
• Speed Grade  This part carries the –1 speed grade designation (approximately 15% faster than standard for SX-A family parts).
• Commercial Temperature  Rated for commercial operation from 0 °C to 70 °C.
• Nonvolatile Single-Chip Configuration  SX-A family devices are provided as nonvolatile, single-chip solutions for retained configuration without external configuration memory (family-level feature).
• System & Test Features  Family features include boundary-scan testing compliant with IEEE 1149.1 (JTAG), in-system diagnostic and verification capability, and configurable I/O behavior at power-up.
• Regulatory  RoHS compliant.

Typical Applications

• Commercial Embedded Systems  Use the A54SX16P-1VQ100 for compact embedded control and logic tasks where moderate gate density and a 100-TQFP footprint are required.
• Interface Control & Glue Logic  Implement protocol adaptation, bus bridging, and glue logic leveraging 81 I/Os and mixed-voltage I/O capability.
• PCI-Enabled Designs  Leverage SX-A family support for 66 MHz PCI signaling for interface and peripheral bridging in commercial systems.
• In-System Diagnostics & Boundary Scan  Integrate JTAG boundary-scan and family diagnostics to simplify testing and bring-up of board-level designs.

Unique Advantages

• Compact, Moderate-Density FPGA  Delivers ~24k system gates and 1,452 logic elements in a 100-pin TQFP, reducing board area while providing useful logic capacity.
• Flexible I/O Voltage Options  Family-level support for mixed 2.5 V / 3.3 V / 5 V operation and 5 V tolerance simplifies interfacing to a wide range of legacy and modern peripherals.
• Nonvolatile, Single-Chip Solution  Eliminates the need for external configuration memory and simplifies system power-up behavior.
• Deterministic Timing & Diagnostics  SX-A family features deliver predictable timing behavior and in-system diagnostic capabilities to shorten development and validation cycles.
• Testability  IEEE 1149.1 (JTAG) boundary-scan support eases board-level testing and manufacturing diagnostics.
• RoHS Compliant  Meets lead-free and restricted-substances requirements for commercial deployments.

Why Choose A54SX16P-1VQ100?

The A54SX16P-1VQ100 strikes a balance between logic capacity, I/O count, and package size for commercial embedded applications that require a nonvolatile, reprogrammable logic device in a compact TQFP footprint. With approximately 1,452 logic elements, 81 user I/Os, and SX-A family system features—such as boundary-scan, in-system diagnostics, and mixed-voltage I/O capability—this device is well suited for designers building interface controllers, glue logic, and moderate-density digital subsystems.

Its –1 speed grade and family-provided system features support projects that need a modest performance uplift and robust test/diagnostic options without external configuration components. RoHS compliance and surface-mount packaging make it appropriate for commercial product assemblies.
