A54SX32A-2BG329

The A54SX32A-2BG329 is a commercial-grade FPGA from Microchip Technology’s SX-A family. It provides a nonvolatile, single-chip FPGA architecture with 48,000 system gates, approximately 2,880 logic elements and up to 249 user I/Os in a 329-ball BGA package.

Designed for system designs that require mixed-voltage I/O, in-system configuration and PCI-compatible interfaces, this device combines high I/O density, configurable I/O standards and on-chip security features to simplify board-level integration and IP protection.

Key Features

• Core & Capacity – Approximately 48,000 system gates and 2,880 logic elements provide a mid-range FPGA resource set for glue-logic, protocol bridging and control plane functions.
• I/O & Interface Flexibility – Up to 249 user-programmable I/Os with configurable support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 to accommodate mixed-voltage systems and legacy interfaces.
• Performance – SX-A family performance characteristics include system-level operation to 250 MHz and internal performance to 350 MHz, with this part using the –2 speed grade (approximately 25% faster than standard).
• Power & Voltage – Wide voltage supply support from 2.25 V to 5.25 V and mixed-voltage operation on I/Os enable flexible power architectures without complex sequencing.
• Security & Test – Nonvolatile single-chip configuration with Actel Secure Programming Technology (FuseLock™) to help protect design IP, plus boundary-scan (IEEE 1149.1) for board-level testability.
• System Reliability – Hot-swap compliant I/Os and power-up/power-down friendly operation reduce system-level power sequencing constraints and support robust board behavior during field events.
• Package & Grade – Supplied in a 329-ball PBGA (31 × 31 mm) package; commercial temperature grade (0 °C to +70 °C). RoHS compliant.
• On-chip Resources – This device reports zero on-chip RAM bits (Total RAM Bits: 0), making it suitable for logic-centric implementations where external memory is preferred.

Typical Applications

• PCI and legacy bus interfaces – Use the device’s 66 MHz PCI compliance and configurable 3.3 V / 5 V I/O support to implement host/bus interface logic and bridge functions.
• Mixed-voltage system glue – High I/O count and mixed-voltage I/O capability make the part well suited for interfacing between 5 V legacy devices and lower-voltage cores.
• Secure configuration and IP protection – Leverage the nonvolatile configuration and FuseLock programming to protect critical firmware and reduce the risk of reverse engineering.
• Hot-swap and field-serviceable boards – Hot-swap compliant I/Os and power-up/power-down friendly behavior enable use on boards that require live insertion/removal or tolerant power sequencing.

Unique Advantages

• High I/O density: Up to 249 user I/Os allow complex board-level interconnects and multiple peripheral interfaces without external multiplexing.
• Mixed-voltage support: Configurable I/O standards and 2.25 V–5.25 V supply range simplify integration with diverse voltage domains.
• Nonvolatile, single-chip solution: Eliminates the need for external configuration memory and supports deterministic power-up behavior.
• Security-focused programming: FuseLock technology helps protect design IP and deter reverse engineering.
• Board-level testability: IEEE 1149.1 boundary-scan support facilitates production test and in-system diagnostics.
• Commercial-grade thermal profile: Rated for 0 °C to +70 °C for board designs targeting commercial environments.
