A54SX08-1FGG144I

The A54SX08-1FGG144I is a nonvolatile SX family FPGA supplied by Microchip Technology, delivered in a compact 144-ball LBGA package for surface-mount assembly. It provides a field-programmable logic platform with 12,000 system gates and 768 logic elements, plus 111 user I/Os, targeted at industrial and embedded control applications.

Built on the SX-A family architecture, the device offers high internal performance and predictable timing characteristics while supporting mixed-voltage I/O and power-up/down friendly operation, making it suitable for designs that require low board-level configuration overhead and I/O flexibility.

Key Features

• Logic Capacity — 12,000 system gates and 768 logic elements for implementing control, glue logic, finite state machines, and small-scale datapaths.
• I/O Count & Flexibility — 111 user I/Os with configurable support for multiple interface voltages; ideal for multi-voltage systems and interface bridging.
• Voltage Supply — Operates from 3 V to 5.5 V, enabling compatibility with a broad range of system power rails.
• No On-Chip RAM — 0 total RAM bits (no embedded RAM), suitable for logic-centric designs that rely on external memory or do not require embedded block RAM.
• Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical paths.
• I/O and Interface Support — Hot-swap compliant I/Os, configurable I/O for 3.3 V / 5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2; supports mixed 2.5 V, 3.3 V, and 5 V operation with 5 V input tolerance and 5 V drive strength.
• Nonvolatile, Single-Chip Solution — Single-chip configuration (nonvolatile) removes the need for external configuration memory and simplifies system initialization.
• Package & Mounting — 144-LBGA package (supplier package: 144-FPBGA 13×13), surface-mount mounting for compact PCB implementations.
• Industrial Temperature Grade — Rated for operation from −40 °C to +85 °C.
• Standards, Test & Security — 66 MHz PCI compliance, boundary-scan testing (IEEE 1149.1 JTAG), deterministic timing, in‑system diagnostics, and secure programming capability with FuseLock technology.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Control — Implement control logic, signal conditioning, and interface glue in industrial systems where extended temperature range and mixed-voltage I/O are required.
• Interface Bridging — Translate or aggregate signals between different voltage domains and legacy/modern interfaces using the device's configurable I/Os and 111 available pins.
• Embedded System Glue Logic — Replace discrete logic, microcontroller peripherals, or CPLDs with a single nonvolatile FPGA to reduce board complexity and BOM count.
• Secure Logic and Functionality — Use the device’s secure programming technology and boundary-scan support to protect and validate in-system logic implementations.

Unique Advantages

• Compact, Surface-Mount Footprint: 144-LBGA package enables higher-density PCB layouts while preserving 111 user I/Os.
• Nonvolatile Single-Chip Design: Eliminates external configuration memory, simplifying power-up behavior and reducing board-level components.
• Flexible I/O Voltage Support: Configurable interface levels (2.5 V, 3.3 V, 5 V) and 5 V tolerant inputs provide compatibility across mixed-voltage systems.
• Industrial Temperature Rating: −40 °C to +85 °C operation supports deployment in industrial and outdoor environments.
• Predictable, High-Speed Operation: SX-A family timing and performance characteristics (250 MHz system, 350 MHz internal) support timing-critical designs.
• Built-in Test and Security Features: Boundary-scan JTAG, in-system diagnostics, and secure programming (FuseLock) streamline manufacturing test and protect IP.
