A54SX32-1PQ208

The A54SX32-1PQ208 is a commercial-grade SX-A family Field Programmable Gate Array from Microchip Technology supplied in a 208-pin BFQFP package. It provides a nonvolatile, single-chip FPGA solution with flexible I/O and deterministic timing suitable for designs that require reconfigurable logic and mixed-voltage I/O support.

Key on-board resources include 2,880 logic elements (LEs), approximately 48,000 system gates of capacity, and 174 user I/O pins. The device supports a wide supply range and standard commercial operating temperatures for mainstream embedded and electronic designs.

Key Features

• Core Performance — SX-A family performance characteristics include published system and internal performance points of up to 250 MHz and 350 MHz respectively.
• Logic Capacity — Provides 2,880 logic elements (approximately 48,000 system gates) for implementing bespoke logic and control functions.
• I/O and Voltage Flexibility — 174 user I/Os with configurable support for multiple voltage standards; devices in the family include 5 V input tolerance and mixed-voltage operation options per datasheet guidance.
• Nonvolatile Single-Chip Solution — On-device nonvolatile configuration enables a single-chip FPGA implementation without external configuration memory.
• Package and Mounting — 208-pin BFQFP / 208-PQFP (28×28) supplier package; surface-mount mounting type for PCB assembly.
• Supply and Temperature — Wide supply range from 3 V to 5.25 V and commercial temperature grade (0 °C to 70 °C).
• System and Test Features — Hot-swap–compliant I/Os, boundary-scan test support (IEEE 1149.1), and in-system diagnostic and verification capability as described for the SX-A family.
• Security — Family-level secure programming technology (FuseLock™) to protect configuration and prevent reverse engineering, as documented in the SX-A family datasheet.
• Regulatory — RoHS compliant.

Typical Applications

• PCI-capable peripherals — Family support for 66 MHz PCI and configurable I/O levels enables implementation of PCI-attached logic and interfacing functions.
• Mixed-voltage system I/O — Use in systems that require level translation or mixed 2.5 V / 3.3 V / 5 V I/O support and 5 V input tolerance.
• In-system diagnostics and verification — Leverage the SX-A family in-system diagnostic capability for validation, verification and manufacturing test flows.
• Boundary-scan test environments — Devices support IEEE 1149.1 boundary-scan for board-level testability and production test integration.

Unique Advantages

• Nonvolatile single-chip FPGA: Eliminates the need for separate configuration memory while providing persistent configuration across power cycles.
• Flexible I/O and mixed-voltage operation: Configurable I/O standards and 5 V tolerance simplify interfacing across different subsystem voltage domains.
• Deterministic timing control: User-controllable timing features help achieve predictable performance in timing-sensitive applications.
• Integrated test and security features: Boundary-scan support and FuseLock programming enhance testability and intellectual-property protection.
• Compact, surface-mount package: 208-pin PQFP/BFQFP packaging with 174 user I/Os balances pin count and board-area efficiency for medium-density designs.
• RoHS compliant, commercial grade: Meets RoHS requirements and is specified for commercial temperature operation (0 °C to 70 °C).
