Key Features

• Capacity & Logic — 24,000 system gates and 1,452 logic elements provide mid-range programmable logic density for interface and control functions.
• I/O Count & Flexibility — Up to 175 user-programmable 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 signaling.
• Mixed‑Voltage Operation — Supports 2.5 V, 3.3 V and 5 V mixed-voltage operation with 5 V input tolerance and 5 V drive strength; supply range 2.25 V to 5.25 V.
• Performance — Family-level documented performance includes up to 350 MHz internal performance and up to 250 MHz system performance.
• Packaging & Mounting — 208-pin BFQFP package; supplier device package listed as 208-PQFP (28×28). Surface-mount mounting type.
• Power & Board Friendliness — Power-up/down friendly (no sequencing required for supply voltages) and hot-swap compliant I/Os to simplify system integration.
• Programmability & Security — Nonvolatile single-chip configuration and Actel Secure Programming Technology (FuseLock) for protecting designs against reverse engineering.
• Test & Diagnostics — In-system diagnostic and verification support with Silicon Explorer II and boundary-scan testing compliant with IEEE 1149.1 (JTAG).
• Operating Range & Compliance — Commercial temperature grade (0 °C to 70 °C) and RoHS compliant.

Typical Applications

• PCI Interface Logic — Use the device’s 66 MHz PCI compliance and configurable I/O to implement PCI interface glue logic and bridging functions.
• Mixed‑Voltage I/O Bridging — Mixed-voltage operation and 5 V tolerant I/Os enable level translation and interface control across 2.5 V, 3.3 V and 5 V domains.
• Hot‑Swap Systems — Hot-swap compliant I/Os and power-up/down friendly behavior make the FPGA suitable for replaceable or live-insert modules requiring safe board insertion/removal.
• In‑System Diagnostic & Verification — Built-in in-system diagnostic capability supports runtime validation and debugging using Silicon Explorer II and JTAG boundary-scan.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates the need for external configuration memory and simplifies board-level BOM and system initialization.
• Flexible Mixed‑Voltage I/O: Reduces external level-shifting components by supporting multiple I/O standards and 5 V tolerance on inputs.
• Deterministic Timing Control: Family-level deterministic, user-controllable timing helps streamline timing closure for predictable system behavior.
• Integrated Security Features: FuseLock secure programming protects intellectual property and prevents reverse engineering of deployed designs.
• Board-Level Friendliness: Hot-swap I/Os and no required supply sequencing reduce integration complexity for modular or serviceable systems.
• Standards-Based Testability: IEEE 1149.1 boundary-scan support enables structured manufacturing test and in-field diagnostics.
