A54SX32-2PQ208I

The A54SX32-2PQ208I is an SX-A family FPGA from Microchip Technology designed for mid-density logic integration in industrial applications. It provides a nonvolatile, single-chip FPGA architecture optimized for mixed-voltage I/O and in-system configurability, making it suitable for embedded control, interface bridging, and I/O-rich designs that require robust industrial temperature operation.

Key Features

• Logic Capacity — Includes approximately 48,000 system gates implemented as 2,880 logic elements, delivering mid-range integration density for glue logic, protocol handling, and control functions.
• I/O and Mixed-Voltage Support — 174 user I/O pins with configurable I/O support for 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2; supports 5 V input tolerance and 5 V drive strength for legacy interfacing.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance, suitable for timing-critical logic and interface tasks.
• Nonvolatile, Single-Chip Architecture — Single-chip FPGA that retains configuration without external memory, simplifying system design and reducing BOM.
• Power and I/O Robustness — Power-up/down friendly (no supply sequencing required) with hot-swap compliant I/Os and configurable weak pull-up/pull-down on I/O at power-up.
• Security and Diagnostics — Family features include Actel Secure Programming technology (FuseLock™) and in-system diagnostic and verification capability via Silicon Explorer II, supporting design protection and debug.
• Standards and Testability — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) for production test and board-level validation.
• Package and Mounting — 208-pin BFQFP package (supplier device package: 208-PQFP, 28×28) designed for surface-mount assembly.
• Supply and Temperature — Operates from 3.0 V to 5.5 V and is rated for industrial temperature operation from −40 °C to +85 °C; RoHS compliant.

Typical Applications

• Industrial Control and Automation — Implement control logic, I/O aggregation, and protocol bridging in equipment that requires industrial temperature operation and mixed-voltage interfacing.
• Interface and Peripheral Bridging — Provide glue logic, bus interfacing and PCI-capable support for systems that mix legacy 5 V devices with modern 3.3 V peripherals.
• Embedded System Glue Logic — Replace discrete logic with a single-chip FPGA to consolidate state machines, address decoding, and custom peripheral control.
• Secure and Testable Designs — Use built-in FuseLock programming and IEEE-1149.1 boundary-scan to protect IP and simplify production test and in-system verification.

Unique Advantages

• Mid-density integration with compact footprint: ~48,000 system gates and 2,880 logic elements provide substantial logic capability in a 208-pin surface-mount package.
• Flexible mixed-voltage I/O: Configurable I/O standards and 5 V tolerance enable straightforward interfacing to both legacy and modern devices without external level shifters.
• Nonvolatile single-chip solution: Eliminates the need for external configuration memory, reducing component count and simplifying board design.
• Industrial temperature rating: Specified operation from −40 °C to +85 °C for deployment in temperature-demanding environments.
• Built-in security and diagnostics: FuseLock programming and Silicon Explorer II support facilitate IP protection and in-system diagnostic capability.
• Production-friendly testability: IEEE 1149.1 (JTAG) boundary-scan support aids board-level testing and manufacturer validation.
