A54SX32-1PQ208M

The A54SX32-1PQ208M is a military-grade SX family Field Programmable Gate Array (FPGA) provided in a 208-pin BFQFP package. It delivers a nonvolatile, single-chip FPGA solution with 48,000 system gates and 2,880 logic elements for control, interfacing and custom digital logic integration.

Key engineering attributes include 174 user I/Os, wide supply voltage support from 3 V to 5.5 V, and an extended operating temperature range from −55 °C to 125 °C, making the device suitable for high-reliability and harsh-environment electronics requiring reconfigurable logic and robust I/O options.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements provide a mid-range density for implementing custom logic, control and interface functions.
• I/O Count and Flexibility — 174 user-programmable I/Os with configurable I/O support for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2, plus 5 V input tolerance and 5 V drive strength options.
• Performance — Series datasheet specifies up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical logic paths.
• Nonvolatile Single-Chip Architecture — On-chip nonvolatile configuration removes the need for external configuration memory and supports power-up/power-down-friendly operation without sequencing requirements.
• System and Test Support — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability via Silicon Explorer II.
• Power and I/O Controls — Hot-swap compliant I/Os, configurable weak pull-up/pull-down at power-up, and individual output slew-rate control for signal integrity and board-level flexibility.
• Security and Resource Control — Actel Secure Programming Technology with FuseLock™ for protection of device programming and 100% resource utilization with 100% pin locking for deterministic mapping.
• Package and Mounting — 208-BFQFP package case (supplier device package: 208-PQFP 28×28) with surface-mount construction appropriate for standard PCB assembly.
• Environmental Grade — Military grade device with operating temperature range of −55 °C to 125 °C.
• Supply Voltage Range — Operates from 3 V to 5.5 V to support mixed-voltage system environments.
• On-Chip Memory — No embedded RAM (total on-chip RAM bits: 0).

Typical Applications

• PCI-based systems — The device’s 66 MHz PCI compliance and multi-voltage I/O support make it suitable for board-level PCI interface logic and bridging.
• Military and high-reliability electronics — Military grade temperature range and surface-mount packaging suit rugged, mission-critical control and signal-processing applications.
• Mixed-voltage interface control — Configurable I/Os and 5 V tolerance enable protocol translation and glue-logic between different voltage domains on complex PCBs.
• Test and verification environments — Boundary-scan (IEEE 1149.1) and in-system diagnostics facilitate manufacturing test, board bring-up and field verification.

Unique Advantages

• Wide operating temperature range: −55 °C to 125 °C supports deployment in extreme and military environments where thermal resilience is required.
• Nonvolatile configuration: Single-chip nonvolatile architecture eliminates external configuration memory, simplifying BOM and boot behavior.
• Flexible voltage interoperability: Native support for multiple I/O standards (PCI/TTL/LVTTL/LVCMOS2) and mixed-voltage operation reduces the need for intermediate level-shifting components.
• Deterministic timing and full resource control: 100% resource utilization and pin locking enable predictable placement and timing for safety- and performance-conscious designs.
• Built-in security and testability: FuseLock programming protection and JTAG boundary-scan provide anti-tamper measures and streamlined test integration.
• Mid-range density with high I/O count: 48,000 gates and 174 user I/Os provide a balance of logic capacity and connectivity for complex control and interface tasks.
