A54SX16A-PQ208A

The A54SX16A-PQ208A is an SX-A family field programmable gate array (FPGA) from Microchip Technology tailored for automotive applications. It is a nonvolatile, single-chip FPGA offering 24,000 system gates and 1,452 logic elements with up to 175 user I/O pins in a 208-pin BFQFP package.

Designed for embedded control and vehicle electronics, the device delivers deterministic timing, configurable I/O support, and wide operating conditions — including AEC-Q100 qualification and an operating range of −40°C to 125°C — for designs that require automotive-grade robustness.

Key Features

• Core & Capacity 24,000 system gates and 1,452 logic elements provide a compact FPGA fabric for control, glue logic, and medium-complexity processing tasks.
• I/O Density Up to 175 user I/O pins support extensive external interfacing for sensors, actuators and bus connectivity.
• Nonvolatile Single-Chip Solution Nonvolatile architecture eliminates the need for external configuration memory and enables instant-on behavior after power-up.
• Performance & Timing Family-level performance capabilities include up to 250 MHz internal operation and deterministic, user-controllable timing for predictable system behavior.
• I/O Capabilities Hot-swap compliant I/Os, configurable support for 3.3V PCI, 3.3V LVTTL and 2.5V LVCMOS2 signaling, configurable weak pull-up/pull-down at power-up, and individual output slew-rate control.
• Security & Test Secure programming technology (FuseLock™) and boundary-scan (IEEE 1149.1 JTAG) support for design protection and board-level testability.
• Power & Supply Wide supply range from 2.25 V to 5.25 V and power-up/down friendly operation with no required sequencing of supply voltages.
• Package & Mounting Surface-mount 208-BFQFP package (supplier package listed as 208-PQFP, 28 × 28 mm) suitable for standard PCB assembly processes.
• Automotive Qualification Automotive grade with AEC-Q100 qualification and an operating temperature range of −40°C to 125°C.
• On-chip Memory No embedded RAM (total RAM bits = 0), enabling predictable resource usage for register- and logic-centric designs.
• Standards & Interfaces Family-level compliance includes 66 MHz PCI capability and in-system diagnostic/verification support (Silicon Explorer II noted in family datasheet).
• Environmental RoHS-compliant device packaging.

Typical Applications

• Automotive Control Electronics — Configurable logic for body control, gateway functions, and domain controllers where AEC-Q100 qualification and wide temperature range are required.
• Sensor Interface & Signal Conditioning — High I/O count and configurable I/O thresholds enable integration of multiple sensors and pre-processing logic.
• Vehicle Networking & Bus Glue Logic — Deterministic timing and nonvolatile configuration support reliable in-vehicle protocol bridging and interface logic.

Unique Advantages

• AEC-Q100 Qualified Automotive Grade: Provides a qualification level and temperature rating appropriate for automotive electronic systems.
• Nonvolatile Single-Chip Design: Eliminates external configuration memory, simplifying bill-of-materials and boot behavior.
• Wide Supply Voltage Range: 2.25 V to 5.25 V support allows integration across mixed-voltage domains without additional level-shifting for supply compatibility.
• Deterministic, User-Controlled Timing: Enables predictable timing behavior for control and gateway logic where timing determinism is important.
• Rich I/O Controls: Hot-swap compliance, configurable pull-ups/pull-downs at power-up, and individual slew-rate control simplify board-level integration and signal integrity tuning.
• Secure Programming & Test Support: FuseLock programming and JTAG boundary-scan improve IP protection and manufacturability.

Why Choose A54SX16A-PQ208A?

The A54SX16A-PQ208A combines a moderate logic capacity (24,000 system gates and 1,452 logic elements) with a high I/O count and automotive-grade qualification, making it well suited for vehicle electronics that require configurable logic, deterministic timing and robust environmental performance. Its nonvolatile architecture and wide supply tolerance simplify system-level design by removing external configuration memory and accommodating mixed-voltage subsystems.

Choose this device for automotive-focused embedded designs that demand predictable timing, secure programming, and extensive I/O integration while operating across −40°C to 125°C and complying with AEC-Q100 qualification.
