A54SX08A-TQG100I

The A54SX08A-TQG100I is a nonvolatile SX-A family FPGA from Microchip Technology configured in a 100‑pin quad flat package. It provides 12,000 system gates with 768 logic elements and 81 user I/Os, targeting industrial-temperature applications that require flexible, reprogrammable logic with mixed‑voltage I/O support.

As a single‑chip, nonvolatile FPGA, the device combines deterministic timing and configurable I/O options to support designs that need reliable in‑system programmability, boundary‑scan testability, and hardware security features from the SX‑A family.

Key Features

• Logic Capacity — 12,000 system gates and 768 logic elements provide the programmable logic resources for medium‑complexity designs.
• User I/O — 81 user‑programmable I/O pins, with configurable weak pull‑up/pull‑down on power‑up and individual output slew rate control.
• Nonvolatile Single‑Chip Architecture — SX‑A family nonvolatile configuration for single‑chip deployment without the need for external configuration memory.
• Performance (SX‑A family) — Family‑level performance up to 250 MHz system performance and up to 350 MHz internal performance (SX‑A family specification).
• Mixed‑Voltage I/O Support — Configurable support for 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and 5 V drive strength (family feature).
• Power and Hot‑Swap Friendly — Power‑up/power‑down friendly operation with hot‑swap compliant I/Os (family feature).
• Packaging — 100‑pin LQFP package. Supplier device package also listed as 100‑TQFP (14×14).
• Supply and Temperature — Wide supply range of 2.25 V to 5.25 V and industrial operating temperature from −40°C to 85°C.
• No On‑Chip RAM — Total embedded RAM bits: 0, for designs that rely on combinational and registered logic resources.
• System Test and Security (family features) — Boundary‑scan (IEEE 1149.1/JTAG) support and Actel Secure Programming Technology (FuseLock™) to protect design IP.
• In‑System Diagnostics — Family support for in‑system diagnostic and verification using Silicon Explorer II (series capability).
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Control — Use the industrial temperature rating and flexible I/O voltage options for control logic, protocol bridging, and I/O expansion in industrial systems.
• Embedded Systems — Implement glue logic, state machines, and custom interfaces where nonvolatile, in‑system reprogrammability and deterministic timing are required.
• Interface and Peripheral Control — Leverage configurable I/O standards and 5 V tolerance for designs that interface with legacy TTL/PCI‑level peripherals and mixed‑voltage subsystems.

Unique Advantages

• Nonvolatile, Single‑Chip Configuration: Eliminates the need for external configuration memory, simplifying board design and improving system reliability.
• Industrial Temperature Support: Rated for −40°C to 85°C operation, suitable for deployments that require extended temperature range.
• Flexible Mixed‑Voltage I/O: Supports 2.5 V, 3.3 V, and 5 V I/O domains with 5 V tolerance and selectable pull directions at power‑up, reducing the need for level‑shifters.
• Security and Testability: Built‑in boundary‑scan and FuseLock™ secure programming technology protect IP and facilitate board‑level testing.
• Deterministic Timing and High Utilization: SX‑A family capabilities enable deterministic, user‑controllable timing and up to 100% resource utilization and pin locking for predictable implementations.
• Tooling and Diagnostics: Series support for Silicon Explorer II provides in‑system diagnostic and verification capabilities during development and production.
