A54SX72A-CQ256

The A54SX72A-CQ256 is a commercial-grade FPGA from Microchip Technology’s SX‑A family, delivered in a 256‑lead ceramic CQFP package with tie bar. It provides a high‑density programmable logic option, combining approximately 108,000 system gates and 6,036 logic elements with a high pin count for complex glue‑logic, control and interface tasks.

Designed for applications that require flexible I/O and wide supply tolerance, this surface‑mount FPGA supports mixed 2.25 V to 5.25 V supplies and up to 203 user I/O pins in the 256‑pin package while meeting RoHS requirements.

Key Features

• Core Logic  Approximately 6,036 logic elements providing a total of 108,000 system gates for implementing medium to high complexity logic functions.
• I/O Capacity  203 user‑programmable I/O pins on the 256‑lead package to support wide peripheral and interface connectivity.
• Supply Voltage Flexibility  Operates across a broad supply range from 2.25 V to 5.25 V, enabling use with multiple voltage domains and interface standards.
• Package & Mounting  256‑BFCQFP (with tie bar) / supplier device package 256‑CQFP (75 × 75) in a surface‑mount format suitable for automated assembly and handling.
• Commercial Temperature Grade  Rated for operation from 0 °C to 70 °C for commercial applications.
• Memory  No embedded on‑chip RAM (Total Ram Bits: 0), useful for deterministic logic implementations that do not rely on internal block RAM.
• RoHS Compliance  Conforms to RoHS requirements for environmentally conscious designs.

Typical Applications

• Consumer and Industrial Electronics  Implement interface logic, protocol bridging and custom control functions in commercial devices where a high I/O count and flexible supply options are required.
• Communications Equipment  Use as glue logic or packet handling accelerators requiring dense combinatorial logic and many I/O connections.
• Test and Measurement  Deploy for custom signal routing, timing control and instrumentation front‑end logic in lab and bench equipment.
• Embedded Control  Perform system control, sequencers and peripheral management in embedded platforms that benefit from configurable logic resources.

Unique Advantages

• High Logic Integration: 6,036 logic elements and 108,000 system gates consolidate complex designs into a single device, reducing board-level component count.
• Large I/O Count: 203 user I/Os in the 256‑lead package enable extensive peripheral and bus connectivity without external multiplexing.
• Wide Supply Range: 2.25 V to 5.25 V operation allows flexible interfacing with multiple voltage domains and legacy interfaces.
• Surface-Mount Ceramic Package with Tie Bar: The 256‑BFCQFP with tie bar aids automated handling and PCB assembly while providing a dense pinout in a compact footprint.
• Commercial Temperature Suitability: Rated 0 °C to 70 °C for applications targeting commercial environments.
• RoHS Compliant: Supports environmentally driven procurement and regulatory needs.
