EP1SGX40DF1020C7

Overview

The Altera EP1SGX40DF1020C7 is a Stratix GX Field Programmable Gate Array (FPGA) housed in a 1020-ball FineLine BGA package. This device features 41,250 logic elements and supports high-speed serial transceivers for data rates up to 3.2 Gbps. It integrates approximately 3.4 Mbits of embedded memory blocks and provides 624 user I/O pins. The core logic operates within a voltage range of 1.425 V to 1.575 V. Designed for demanding communication applications, the chip supports complex digital signal processing and protocol conversion tasks.

Feature Summary

• Stratix GX architecture with 41,250 logic elements and 3.4 Mbits of embedded RAM
• Integrated high-speed serial transceivers supporting up to 3.2 Gbps data rates
• 1020-ball FineLine BGA package with 624 available I/Os
• Supports advanced clocking resources including DLLs and PLLs for precise timing

Applications

• Very Short Reach (VSR) optical transmission systems for STM-64/OC-192 frames
• High-speed network switches and routers requiring parallel optical interfaces
• Digital signal processing in telecommunications infrastructure
• Protocol conversion between different serial data standards

Procurement Notes

Verify the specific suffix 'D' against official Intel/Altera documentation to confirm temperature grade and packaging variant. Ensure compatibility with Quartus Prime software versions that support the Stratix GX family. Check for end-of-life status or lifecycle recommendations before finalizing procurement plans.

Selection Notes

Select this component when designs require high-density logic combined with moderate-speed serial connectivity. Compare against Stratix II or Arria series if higher transceiver speeds or lower power consumption are required. Verify that the 1020-pin footprint fits the target PCB constraints and thermal management requirements.

Part Context

This part belongs to the Stratix GX family, which was designed for cost-effective high-performance applications. It bridges the gap between standard logic FPGAs and high-end Stratix devices by offering integrated serial links without the complexity of the highest-tier models.

Replacement Considerations

Direct pin-to-pin replacements may not exist due to architectural differences. Consider Intel Agilex or Stratix 10 families for modern equivalents, though these require significant design re-verification and potentially new toolchains.
