A54SX32-2PQG208

The A54SX32-2PQG208 is a member of the SX-A family of nonvolatile FPGAs, delivered in a 208-pin BFQFP package. It provides 48,000 system gates across approximately 2,880 logic elements and 174 user-programmable I/Os, making it suitable for mid-density programmable logic tasks where predictable, in-system configuration and mixed-voltage I/O are required.

Designed for commercial-temperature applications, the device supports mixed-voltage operation and a broad supply range, enabling flexible digital interfacing and reliable single-chip programmable logic integration for a range of embedded designs.

Key Features

• Logic Capacity  Approximately 2,880 logic elements and 48,000 system gates provide mid-range logic integration for glue-logic, control, and interface functions.
• User I/O  174 user-programmable I/Os with configurable support for multiple signaling families (including 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2) to simplify direct interfacing with legacy and modern peripherals.
• Performance  SX-A family performance targets listed in the datasheet include system performance up to 250 MHz and internal performance up to 350 MHz for demanding timing paths.
• Nonvolatile Single-Chip Solution  On-chip nonvolatile configuration eliminates the need for external configuration memory, enabling instantaneous configuration at power-up.
• I/O Robustness  5 V input tolerance, 5 V drive strength and configurable weak pull-up/pull-down on I/Os at power-up improve board-level interoperability and signal integrity during sequencing or hot-swap events.
• Security and Test  Family features include Actel Secure Programming technology (FuseLock™) to protect bitstream intellectual property, plus IEEE-1149.1 JTAG boundary-scan for board-level test and in-system diagnostics.
• Package & Mounting  Surface-mount 208-pin BFQFP package (supplier device package documented as 208-PQFP, 28×28) for standard PCB assembly processes.
• Supply & Temperature  Operates from 3.0 V to 5.25 V and is specified for commercial temperature operation from 0 °C to 70 °C.
• Standards & Compliance  RoHS-compliant packaging option is indicated, supporting lead-free manufacturing requirements.

Typical Applications

• PCI Interface Logic  Use in PCI-compliant interface functions and protocol glue-logic where mixed 3.3 V/5 V signaling and deterministic timing are required.
• Embedded Control  Implements mid-density control logic and state machines for industrial and commercial embedded systems within the commercial temperature range.
• I/O Concentration and Level Translation  Consolidates multiple peripheral interfaces and performs level translation between differing voltage domains thanks to configurable I/O and 5 V tolerance.

Unique Advantages

• Mid-Density Integration:  Combines ~2,880 logic elements and 48,000 system gates to reduce external glue logic and lower BOM in mid-complexity designs.
• Flexible Mixed-Voltage I/O:  Configurable I/O families and 5 V tolerance simplify interfacing with a wide range of legacy and modern devices without additional level-shifters.
• Nonvolatile Configuration:  Single-chip, nonvolatile architecture removes the need for external configuration memory and streamlines system power-up behavior.
• Security & Diagnostics:  Built-in programming protection (FuseLock™) and JTAG boundary-scan support enable secure deployment and in-system testability.
• Commercial Temperature Rated:  Specified for 0 °C to 70 °C operation, matching typical commercial embedded product environments.
• RoHS-Compliant Packaging:  Packaging options compliant with RoHS requirements facilitate lead-free assembly and regulatory alignment.
