A54SX16P-TQG176

The A54SX16P-TQG176 is a commercial-grade SX family Field Programmable Gate Array (FPGA) in a 176-pin thin LQFP package. It provides a nonvolatile, single-chip programmable fabric with 24,000 system gates and 1,452 logic elements for mid-density embedded logic and interface tasks.

Designed for mixed-voltage systems and flexible I/O configurations, this device targets applications that need reliable logic integration, configurable I/O support, and on-board security and testability features while operating within standard commercial temperature and supply ranges.

Key Features

• Core Capacity — 24,000 system gates and 1,452 logic elements provide substantial mid-range programmable logic capacity for glue logic, protocol bridging, and control functions.
• I/O and Packaging — Up to 147 user I/O pins in a 176-LQFP surface-mount package (176-TQFP, 24×24 footprint) for dense board-level connectivity.
• Mixed-Voltage I/O — Configurable I/O support for multiple voltage standards with 5 V input tolerance and 5 V drive strength, enabling direct interfacing to 5 V and 3.3 V domains.
• Performance — Family-level performance indicators include up to 250 MHz system performance and up to 350 MHz internal performance for timing-critical functions.
• Power-Up/Down Friendly — Power sequencing is not required for supply voltages, simplifying system power management and hot-swap scenarios.
• Security and Testability — Built-in secure programming technology and Boundary-Scan (IEEE 1149.1 JTAG) support help protect designs and simplify board-level testing and diagnostics.
• Operating Range — Commercial grade operation with a supply voltage range from 3.00 V to 5.25 V and an operating temperature range of 0 °C to 70 °C.
• Standards Compliance — Family-level features include 66 MHz PCI compliance and configurability for PCI and other common I/O standards.
• RoHS Compliant — Meets RoHS environmental requirements for lead-free assembly and manufacturing.

Typical Applications

• PCI and legacy bus interfacing — Use the device’s PCI compliance and mixed-voltage I/O to implement bus bridges, protocol adapters, and interface controllers.
• Embedded control and glue logic — 1,452 logic elements and 24,000 gates are suitable for consolidating discrete logic, state machines, and control functions into a single programmable device.
• System I/O expansion — With 147 user I/Os and configurable voltage support, the FPGA can centralize signal routing and level translation for complex boards.
• Secure, in-system programmable designs — Nonvolatile single-chip architecture and secure programming capabilities enable field updates and protect IP against reverse engineering.

Unique Advantages

• Highly integrated mid-range logic: 24,000 system gates and 1,452 logic elements reduce external components and simplify PCB layouts.
• Flexible mixed-voltage interfacing: 3.0 V–5.25 V supply range with 5 V input tolerance supports direct connection to multiple legacy and modern logic levels.
• No power-sequencing requirement: Power-up/down friendliness simplifies power-rail design and enables safer hot-swap operations.
• Built-in security and test features: Secure programming technology and JTAG boundary-scan support streamline manufacturing test and help protect design IP.
• Commercial temperature and RoHS compliance: Commercial-grade temperature rating (0 °C to 70 °C) and RoHS status support standard product lifecycles and regulatory needs.
• Proven family-level performance: Family specifications list high internal and system clock performance suitable for timing-sensitive embedded functions.
