A54SX32A-2PQ208I

The A54SX32A-2PQ208I is a nonvolatile SX-A family FPGA offered by Microchip Technology, packaged in a 208-pin BFQFP. It provides a mid-range logic capacity and a rich set of configurable I/O for use in industrial and embedded designs requiring deterministic timing and in-system diagnostics.

Designed for mixed-voltage operation and industrial temperature ranges, this device targets system and peripheral control, embedded processing glue logic, and interfaces where nonvolatile single-chip configurability and robust I/O flexibility are required.

Key Features

• Logic Capacity: Approximately 48,000 system gates implemented as 2,880 logic elements, supporting a range of moderate-complexity logic functions.
• I/O and Package: 174 user-programmable I/O pins in a 208-BFQFP (208-PQFP, 28×28) surface-mount package—suited for dense, board-level implementations.
• Core Performance: SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family specification).
• Nonvolatile Single-Chip Configuration: Single-chip, nonvolatile architecture eliminates the need for external configuration memory and supports deterministic, user-controllable timing.
• Mixed-Voltage I/O and Wide VCC Range: Configurable I/O supports multiple voltage standards with a device supply range of 2.25 V to 5.25 V and 5 V input tolerance (family-level capability).
• Industrial Grade and Temperature Range: Rated for industrial operation with an operating temperature range of −40 °C to 85 °C.
• System Reliability and Test: Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability (Silicon Explorer II) for easier production test and field diagnostics (family features).
• Mounting and Compliance: Surface-mount device with RoHS-compliant status.

Typical Applications

• Industrial Control: Implement motor control logic, timing-critical I/O sequencing, and interface bridging where industrial temperature range and robust I/O are required.
• PCI and Peripheral Interfaces: Use in PCI-compliant peripheral logic and interface adaptation thanks to family-level PCI support and configurable I/O voltage options.
• Embedded System Glue Logic: Replace multiple discrete components with a single nonvolatile FPGA for board-level glue logic and control functions.
• In-System Diagnostics and Test: Leverage boundary-scan and the family’s in-system diagnostic capabilities for manufacturing test, debugging, and field verification.

Unique Advantages

• Nonvolatile Single-Chip Solution: Eliminates external configuration memory and simplifies power-up sequencing for more predictable system behavior.
• Flexible I/O and Voltage Support: Wide supply voltage range and configurable I/O enable mixed-voltage designs and 5 V-tolerant interfaces, reducing the need for level-shifters.
• Deterministic Timing: User-controllable timing and predictable performance characteristics support timing-critical designs.
• Industrial Qualification: Rated for −40 °C to 85 °C operation, making it suitable for industrial environments.
• Production Test and Security: Boundary-scan support and family-level Secure Programming Technology help streamline manufacturing test and protect design IP.
