EP3C40Q240C8N

The EP3C40Q240C8N is an Intel Cyclone® III FPGA in a 240-pin BFQFP surface-mount package. It provides a mid-range density FPGA fabric with 39,600 logic elements and approximately 1.16 Mbits of embedded memory, designed for cost- and power-sensitive commercial applications.

Targeted at system designers needing flexible, low-power programmable logic, this device combines significant on-chip memory and I/O capacity with a low-voltage core supply (1.15 V to 1.25 V) and commercial temperature rating (0 °C to 85 °C).

Key Features

• Logic Capacity — 39,600 logic elements implemented across 2,475 logic blocks to support medium-complexity HDL designs and custom logic integration.
• Embedded Memory — Total on-chip RAM of 1,161,216 bits, or approximately 1.16 Mbits, for buffers, FIFOs, and state storage.
• I/O Resources — 128 user I/Os to interface with peripherals, sensors, and external logic.
• Clock Management — Cyclone III family architecture includes multiple phase-locked loops (PLLs) for flexible clock synthesis and distribution.
• Low-Voltage Core — Core supply range of 1.15 V to 1.25 V supports low-power system designs.
• Package & Mounting — 240-BFQFP (supplier package 240-PQFP, 32×32) in a surface-mount form factor for PCB assembly.
• Commercial Grade — Rated for operation from 0 °C to 85 °C for standard commercial applications.
• RoHS Compliant — Environmentally compliant with RoHS requirements.

Typical Applications

• Embedded Control — Implement custom control logic, state machines, and glue logic for consumer and industrial equipment within a commercial temperature range.
• High-Speed Interfaces — Use the device's 128 I/Os and clock-management resources to implement parallel or serialized interfaces and bridge functions.
• Signal Processing — Leverage the 39,600 logic elements and on-chip memory for moderate-density signal processing, buffering, and packet handling tasks.
• Prototyping & Custom ASIC Replacement — Flexible FPGA fabric for iterative development, feature upgrades, and reducing time-to-market for custom digital logic.

Unique Advantages

• Balanced Logic and Memory: 39,600 logic elements paired with ~1.16 Mbits of embedded RAM deliver a strong mix of combinational and storage resources for mid-range designs.
• Generous I/O Count: 128 user I/Os simplify system integration and reduce the need for additional interface components.
• Low-Voltage Operation: 1.15 V–1.25 V core supply supports low-power system architectures and efficient power budgeting.
• Compact Surface-Mount Package: 240-pin BFQFP (240-PQFP 32×32) enables high-density PCB layouts while remaining compatible with standard SMT assembly.
• Commercial Temperature Rating: Specified 0 °C–85 °C operation aligns with a wide range of consumer and commercial product environments.
• RoHS Compliance: Environmentally compliant manufacturing and disposal considerations met out of the box.
