A54SX08A-FTQG100

The A54SX08A-FTQG100 is a commercial-grade SX-A family Field Programmable Gate Array (FPGA) from Microchip Technology. It delivers a nonvolatile, single‑chip programmable logic solution with 12,000 system gates and 768 logic elements for compact reconfigurable designs.

Targeted at commercial embedded applications that require reprogrammable logic and flexible I/O, this device combines mixed‑voltage I/O capability, hot‑swap compliance, and on‑chip security and diagnostic features to simplify system integration and in‑system verification.

Key Features

• Logic Capacity — 12,000 system gates and 768 logic elements provide a compact programmable fabric for glue logic, interface functions, and small-scale control logic.
• I/O Count & Flexibility — 81 user I/O pins with configurable support for multiple signaling standards; family-level support includes 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL and 2.5 V LVCMOS2 options.
• Performance (SX‑A family) — Family-level performance targets include up to 250 MHz system performance and up to 350 MHz internal performance.
• Power & Voltage — Operates from 2.25 V to 5.25 V and supports mixed‑voltage operation with 5 V input tolerance and 5 V drive strength, enabling flexible board power architectures.
• Nonvolatile Single‑Chip Solution — On-chip nonvolatile configuration removes the need for external configuration memories.
• System Reliability & I/O Behavior — Hot‑swap compliant I/Os and power‑up/power‑down friendly behavior require no special supply sequencing at power‑up.
• Security & Test — Includes Actel Secure Programming Technology (FuseLock™) to protect design IP, plus boundary‑scan testing compliant with IEEE 1149.1 (JTAG).
• Diagnostics & In‑System Verification — Family supports unique in‑system diagnostic capability with Silicon Explorer II for visibility and debugging.
• Package & Environmental — Supplied in a 100‑pin LQFP package (supplier device package: 100‑TQFP (14×14)); RoHS compliant. Rated for commercial temperature operation from 0 °C to 70 °C.
• On‑Chip Memory — Total on‑chip RAM: 0 bits (no embedded RAM).

Typical Applications

• Commercial Embedded Control — Implement control logic, state machines, and system glue for commercial products that require reprogrammable logic in a compact package.
• Interface Bridging and Peripheral Control — Useful for PCI‑class interfaces and other peripheral bridging tasks where configurable I/O standards and 66 MHz PCI compatibility at the family level are beneficial.
• Prototyping and In‑System Verification — Nonvolatile configuration and Silicon Explorer II support enable rapid prototype iterations and on‑board diagnostics.
• Compact Board Designs — 100‑pin LQFP packaging and mixed‑voltage I/O support help minimize board area and reduce the need for level‑shifters in space‑constrained systems.

Unique Advantages

• Compact, Reprogrammable Logic — 12,000 system gates and 768 logic elements provide sufficient logic density for many glue‑logic and control applications while keeping BOM complexity low.
• Flexible I/O Voltage Support — Mixed‑voltage operation (2.5 V, 3.3 V, 5 V) with 5 V tolerance simplifies interfacing to legacy and modern devices without extra components.
• Nonvolatile Configuration — Eliminates external configuration flash or EEPROM, simplifying board design and improving system reliability.
• Design Security — FuseLock™ secure programming technology helps protect intellectual property against reverse engineering.
• Power Sequencing Simplicity — Power‑up/power‑down friendly I/O behavior and hot‑swap compliance reduce constraints on supply sequencing and improve system robustness.
• Diagnostics and Testability — Built‑in JTAG boundary‑scan and family diagnostic tools support manufacturing test and in‑field debugging.
