A54SX16A-1PQG208

The A54SX16A-1PQG208 is a nonvolatile SX‑A family Field Programmable Gate Array from Microchip Technology, provided in a 208‑pin BFQFP surface‑mount package. It delivers a reprogrammable logic resource of 24,000 system gates with 1,452 logic elements and 175 user I/O pins, targeted at embedded designs that require configurable I/O and deterministic timing.

Designed for commercial‑grade systems, the device supports mixed‑voltage operation across a broad supply range (2.25 V to 5.25 V), RoHS‑compliant packaging, and an operating temperature range of 0 °C to 70 °C.

Key Features

• Core Performance — Series-level performance includes up to 250 MHz system performance and 350 MHz internal performance for time-critical logic paths.
• Logic Capacity — Approximately 24,000 system gates implemented as 1,452 logic elements to support medium‑complexity FPGA designs.
• User I/O — 175 user‑programmable I/O pins with configurable I/O support for multiple voltage standards, enabling flexible interfacing to mixed‑voltage systems.
• Power and Voltage — Wide supply range from 2.25 V to 5.25 V to accommodate multiple system rails and mixed‑voltage operation.
• Package and Mounting — 208‑pin BFQFP (supplier device package: 208‑PQFP, 28×28) in a surface‑mount form factor for compact PCB designs.
• Memory — No embedded RAM (Total Ram Bits: 0), delivering a predictable, register‑centric resource model for control and glue‑logic functions.
• System Reliability & Security — Family features include nonvolatile single‑chip configuration and Actel Secure Programming Technology (FuseLock™) to protect designs from reverse engineering.
• Design and Test Support — Series support for boundary‑scan (IEEE 1149.1 JTAG) and in‑system diagnostic/verification capabilities.
• Regulatory & Grade — Commercial grade device (0 °C to 70 °C) with RoHS‑compliant packaging.

Typical Applications

• PCI Interface and Bridging — With 66 MHz PCI compliance in the SX‑A family and configurable multi‑voltage I/O, the device is suitable for PCI interface logic and glue‑logic functions.
• Embedded Control and Glue Logic — The combination of 1,452 logic elements and deterministic timing supports glue logic, protocol handling, and system control tasks.
• Mixed‑Voltage System Integration — Wide supply range and configurable I/O make the device useful for designs requiring level translation and interfacing between 2.5 V, 3.3 V, and 5 V domains.
• In‑system Diagnostic and Verification — Built‑in diagnostic capabilities support field debug and verification during system bring‑up.

Unique Advantages

• Nonvolatile Single‑Chip Solution: Eliminates the need for external configuration memory, simplifying board design and improving system robustness.
• Flexible I/O and Mixed‑Voltage Support: Configurable I/O conventions and wide supply range reduce BOM complexity when interfacing to diverse peripherals.
• Predictable, Register‑Centric Architecture: Absence of embedded RAM and a known count of logic elements (1,452) simplify resource planning for control and interface functions.
• Commercial Temperature Grade: Rated for 0 °C to 70 °C operation, suitable for a wide range of standard electronic products and environments.
• Security and Testability: Series security features and JTAG boundary‑scan support protect IP and facilitate production testing and in‑field diagnostics.
• Compact Surface‑Mount Package: 208‑pin BFQFP in a 28 × 28 supplier PQFP outline provides a high pin count in a familiar SMD footprint.
