• Performance — Family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance as documented for SX‑A devices.
• Package — 208‑pin BFQFP package (supplier device package listed as 208‑PQFP, 28×28), suitable for surface‑mount assembly.
• Industrial Temperature Grade — Rated for operation from −40 °C to +85 °C.
• Power and I/O Robustness — Hot‑swap compliant I/Os and power‑up/power‑down friendly operation (no sequencing required for supply voltages) as noted for the SX‑A family.
• No On‑Chip RAM — Total RAM bits: 0 (no embedded RAM reported for this device).
• Security and Testability — Family features include FuseLock secure programming technology and IEEE 1149.1 (JTAG) boundary‑scan testing capability.
• Standards and Tools — SX‑A family supports deterministic timing and in‑system diagnostics with Silicon Explorer II (as documented for the family).
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• Industrial Control — Use the industrial temperature rating and flexible I/O to implement control logic and interface conversions in factory and process automation equipment.
• Mixed‑Voltage Interface Bridging — Configurable I/O and 5 V input tolerance allow implementation of level‑translation and protocol bridging between legacy 5 V logic and modern lower‑voltage domains.
• PCI‑Related Logic — SX‑A family devices document 66 MHz PCI compliance and 3.3 V/5 V PCI I/O support, making the device suitable for PCI interface glue logic and protocol handling.
• Deterministic Timing Designs — Deterministic, user‑controllable timing features are suited for designs that require predictable timing behavior and in‑system verification.

Unique Advantages

• Nonvolatile, Single‑Chip Solution: Retains configuration without external configuration memory, simplifying board-level design and reducing BOM.
• Flexible I/O Voltage Support: Configurable I/O standards and a broad supply range (2.25 V to 5.25 V) enable direct interfacing to multiple logic families.
• Industrial Reliability: Specified operation from −40 °C to +85 °C for deployment in industrial temperature environments.
• Built‑In Security and Test: Family features such as FuseLock programming and JTAG boundary‑scan support protect IP and simplify manufacturing test.
• Hot‑Swap and Power‑Cycle Robustness: Hot‑swap compliant I/Os and no required supply sequencing reduce system complexity for hot‑plug or multi‑rail systems.
• Compact, High‑I/O Package: 208‑pin PQFP/BFQFP package provides up to 175 user I/Os in a surface‑mount form factor for space‑constrained boards.
