EP1S40B956I6

The EP1S40B956I6 is a Stratix® series field programmable gate array (FPGA) from Altera designed for industrial applications requiring substantial logic, memory and I/O capacity in a compact BGA package. It combines 41,250 logic elements and approximately 3.4 Mbits of embedded RAM with a 683-pin I/O footprint to address mid-range FPGA design requirements.

Packaged in a 956-ball BGA (40×40) and specified for an operating range of –40 °C to 100 °C with a core voltage supply of 1.425 V to 1.575 V, this device is targeted at industrial systems where integration density, robust thermal range and high I/O count are important.

Key Features

• Core Logic 41,250 logic elements provide a substantial base of programmable logic for implementing custom hardware functions and control logic.
• Embedded Memory Approximately 3.4 Mbits of on-chip RAM for buffering, state storage and embedded data processing without relying solely on external memory.
• I/O Capacity 683 user I/O pins support dense peripheral connectivity and complex board-level interfaces.
• Package & Mounting 956-ball BGA (40×40) package in a surface-mount form factor for high-density PCB integration and reliable solder connections.
• Power Core voltage supply specified at 1.425 V to 1.575 V to match system power-rail design and ensure predictable power behavior.
• Industrial Temperature Rating Rated for operation from –40 °C to 100 °C, suitable for a wide range of industrial environments.
• Regulatory RoHS compliant, aiding conformity with environmental material restrictions.

Typical Applications

• Industrial Automation Implement motor control, real-time logic, and sensor interfacing where industrial temperature range and robust I/O are required.
• Communication Equipment Provide protocol handling, logic processing and high pin-count interfacing in network or infrastructure modules.
• Test & Measurement Support custom data acquisition, on-chip buffering and control logic for instrumentation and diagnostic platforms.
