A54SX16A-PQG208

The A54SX16A-PQG208 is a commercial-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 compact embedded logic and interface designs.

Designed for commercial embedded systems, the device combines flexible mixed-voltage I/O, JTAG boundary-scan support and in-system diagnostic capabilities to address applications that require reconfigurable logic, deterministic timing and up to 175 user-configurable I/Os.

Key Features

• Logic Capacity — 24,000 system gates and approximately 1,452 logic elements (cells) provide mid-range programmable logic density for control and interface functions.
• User I/O and Package — 175 user I/Os in a 208-pin BFQFP package (supplier package: 208-PQFP 28×28), surface-mount, RoHS-compliant package for space-efficient board layouts.
• Voltage and I/O Flexibility — 2.25 V to 5.25 V supply range with configurable I/O support for multiple voltage standards and mixed-voltage operation; devices support 5 V input tolerance and 5 V drive strength as part of the SX-A family capabilities.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family specifications).
• Nonvolatile, Single-Chip Solution — Nonvolatile configuration storage on-chip simplifies system design by removing external configuration memory.
• Hot-Swap and Power Handling — Hot-swap compliant I/Os and power-up/power-down friendly operation with no supply sequencing required (family features).
• Diagnostics and Security — In-system diagnostic and verification capability with Silicon Explorer II and Actel Secure Programming Technology (FuseLock) to help protect IP (family features).
• Standards and Testability — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) for production test and board-level debug.
• Operating Conditions — Commercial grade with an operating temperature range of 0 °C to 70 °C.

Typical Applications

• Embedded Control — Implement mid-density control logic, glue logic and state machines where nonvolatile configuration and deterministic timing are required.
• Interface Bridging — Support mixed-voltage interfacing and protocol bridging, including PCI-relevant I/O configurations indicated by SX-A family features.
• System Prototyping and Verification — Use in-system diagnostic capabilities for iterative development, verification and in-field updates.
• Peripheral and I/O Expansion — Add programmable I/O functionality and custom peripherals to commercial electronic systems using the device’s 175 user I/Os.

Unique Advantages

• Integrated, Nonvolatile Logic: Single-chip nonvolatile configuration eliminates the need for external configuration PROM and simplifies BOM and board design.
• Flexible Mixed-Voltage I/O: Support for multiple I/O voltage standards and 5 V tolerance reduces the need for external level-shifting and enables direct interfacing with legacy logic.
• Deterministic Timing: User-controllable timing and family performance headroom help designers meet real-time and high-speed control requirements.
• Built-in Test and Security: Boundary-scan (IEEE 1149.1), in-system diagnostics, and FuseLock programming support production testability and IP protection.
• Commercial Temperature Footprint: Specified for 0 °C to 70 °C operation, matching typical commercial electronics deployment requirements.
