A54SX16A-2PQG208

The A54SX16A-2PQG208 is a member of the SX-A family of nonvolatile, single-chip FPGAs. It provides 24,000 system gates and 1,452 logic elements with 175 user I/Os in a 208-pin surface-mount package, making it suitable for commercial embedded designs that require flexible programmable logic and mixed-voltage I/O support.

As an SX-A family device, it supports family-level performance up to 250 MHz system performance and 350 MHz internal performance and includes features such as hot-swap compliant I/Os, configurable I/O standards, and in-system diagnostic capabilities to simplify integration and verification.

Key Features

• Logic Capacity — 24,000 system gates and 1,452 logic elements provide a compact programmable fabric for combinatorial and sequential logic implementations.
• I/O Flexibility — 175 user I/Os with configurable support for mixed-voltage operation (2.5 V, 3.3 V, and 5 V), 5 V input tolerance and selectable drive strength to interface with a wide range of peripherals.
• Voltage and Power — Wide supply range from 2.25 V to 5.25 V and power-up/down friendly operation that requires no sequencing of supply voltages.
• Package and Mounting — 208-pin BFQFP / PQFP (28×28) surface-mount package for compact board-level integration.
• Performance and Speed Grade — Delivered as speed grade "-2" (part suffix -2), consistent with SX-A family speed options; family datasheet lists up to 250 MHz system and 350 MHz internal performance.
• Security and Test — Actel Secure Programming technology with FuseLock™ for protection against reverse engineering and design theft, plus IEEE 1149.1 (JTAG) boundary-scan support for board-level testability.
• Design Control and Reliability — Deterministic, user-controllable timing, configurable weak pull-up/pull-down at power-up, individual output slew-rate control, and up to 100% resource utilization with 100% pin locking.
• Grade and Environment — Commercial grade device with an operating temperature range of 0 °C to 70 °C and RoHS compliance for environmental compatibility.

Typical Applications

• PCI and Bus Interfaces — Use where 66 MHz PCI compliance and configurable I/O signaling are needed to implement custom bus logic or bridging functions.
• Mixed-Voltage Embedded Systems — Integrate into systems that require 2.5 V, 3.3 V, and 5 V signaling with 5 V tolerant inputs for flexible peripheral interfacing.
• In-System Debug and Verification — Employ on boards that benefit from boundary-scan (JTAG) testing and the SX-A family’s in-system diagnostic capabilities for validation and troubleshooting.
• Compact Programmable Logic — Implement glue logic, protocol handling, or control functions in space-constrained commercial products using the 208-pin surface-mount package.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates the need for external configuration memory, simplifying BOM and boot-up behavior.
• Wide I/O Voltage Support: Mixed-voltage I/O and 5 V tolerance enable direct interfacing to legacy and modern peripherals without level-shifter complexities.
• Deterministic Timing Control: User-controllable timing helps achieve predictable behavior for timing-sensitive logic and communication endpoints.
• Security Features: FuseLock™ secure programming reduces the risk of reverse engineering and protects intellectual property on-device.
• Board-Level Testability: IEEE 1149.1 boundary-scan support eases manufacturing test and in-field diagnostics.
• Commercial Temperature Suitability: Rated for 0 °C to 70 °C operation and RoHS compliant for mainstream commercial applications.
