A54SX16P-PQ208

The A54SX16P-PQ208 is a nonvolatile SX-A family FPGA provided in a 208-pin BFQFP/PQFP package. It delivers a compact programmable logic solution with 24,000 system gates and 1,452 logic elements, and supports 175 user I/Os for flexible interface and glue-logic applications.

Designed for commercial embedded designs, the device operates from a 3 V to 5.25 V supply and across a 0 °C to 70 °C commercial temperature range, and includes series-level features such as deterministic timing, in-system diagnostics, and secure programming options.

Key Features

• Core Performance — SX-A family performance characteristics including up to 250 MHz system performance and up to 350 MHz internal performance as specified for the family.
• Logic Capacity — 24,000 system gates and approximately 1,452 logic elements to implement control, glue logic, and medium-density custom logic functions.
• User I/O — 175 user-programmable I/Os with configurable I/O options. I/Os support mixed-voltage operation and 5 V input tolerance as defined for the SX-A family.
• Memory — Total on-chip RAM bits: 0 (no embedded RAM).
• Power and Voltage — Operates from 3 V to 5.25 V supply. Family-level support for mixed 2.5 V, 3.3 V, and 5 V I/O operation and 5 V drive strength.
• Package & Mounting — 208-pin BFQFP / PQFP package (supplier device package 208-PQFP 28 × 28), surface-mount mounting type, RoHS compliant.
• System Reliability & Test — Boundary-scan testing compliant with IEEE 1149.1 (JTAG) and in-system diagnostic/verification capability available through family tools.
• Power-Up/Down Friendly — Family-level support for no required sequencing of supply voltages; hot-swap compliant I/Os and configurable weak pull-up or pull-down at power-up.
• Security & Control — Family-provided secure programming technology and selectable output slew-rate control for signal integrity management.
• Grade — Commercial grade device with operating temperature from 0 °C to 70 °C.

Typical Applications

• PCI interface and bridge logic — Family support for 66 MHz PCI and configurable 3.3 V/5 V PCI I/O makes the device suitable for PCI glue logic and interface bridging.
• Custom I/O aggregation — High I/O count and mixed-voltage support enable aggregation and translation of multiple peripheral interfaces in compact systems.
• In-system diagnostics and verification — Built-in support for in-system diagnostic tools and JTAG boundary-scan facilitates hardware bring-up and board-level testing.
• Hot-swap and power-sequencing-sensitive designs — Hot-swap compliant I/Os and power-up/down friendly behavior reduce system-level power sequencing constraints.

Unique Advantages

• Nonvolatile single-chip solution: Eliminates the need for external configuration memory and simplifies board-level design.
• Flexible mixed-voltage I/O: Configurable I/O levels and 5 V input tolerance support interfacing to a wide range of legacy and modern peripherals.
• Deterministic, user-controllable timing: Family-level deterministic timing features help meet timing closure and predictable system behavior.
• High I/O density in a standard package: 175 user I/Os in a 208-pin PQFP/BFQFP footprint enable compact integration without large BGA packages.
• Integrated test and security features: Boundary-scan (IEEE 1149.1), in-system diagnostics, and secure programming technology provide testability and IP protection.
• RoHS compliant: Meets lead-free environmental requirements for commercial electronics manufacturing.

Why Choose A54SX16P-PQ208?
