EP3SL70F780C3N

The EP3SL70F780C3N is a Stratix® III L Field Programmable Gate Array (FPGA) manufactured by Intel. It combines a large logic fabric with on-chip embedded memory and flexible I/O to implement complex, custom digital functions.

Designed for commercial-grade applications, the device offers 67,500 logic elements, approximately 2.7 Mbits of embedded memory, and 488 general-purpose I/O in a 780-ball FCBGA package. Key value propositions include substantial integration density, a broad I/O complement, and architecture-level features documented in the Stratix III Device Handbook.

Key Features

• Core Logic  67,500 logic elements provide capacity for complex combinational and sequential logic implementation.
• Embedded Memory  Approximately 2.7 Mbits of on-chip RAM support data buffering, FIFOs, and local storage for implemented functions.
• I/O Resources  488 I/O pins enable extensive external connectivity and interfacing to peripherals and external memories.
• Device Architecture (as documented)  Stratix III architectural elements referenced in the device handbook include TriMatrix embedded memory blocks, DSP blocks, multi-track interconnect, clock networks and PLLs, and high-speed differential I/O support with DPA.
• System and Configuration  Device handbook topics include configuration options, IEEE 1149.1 (JTAG) boundary-scan testing, design security, SEU mitigation, and programmable power features.
• Package & Mounting  780-BBGA (FCBGA) supplier device package, 29 × 29 mm, surface-mount mounting type for compact board-level integration.
• Electrical & Environmental  Core supply voltage range 0.860 V to 1.15 V; commercial operating temperature range 0 °C to 85 °C. RoHS compliant.

Typical Applications

• High-bandwidth external memory interfaces  488 I/O and the device’s embedded memory resources support designs that require external memory controllers and wide memory buses.
• Signal processing and DSP functions  Architecturally supported DSP blocks and a large logic element count enable implementation of custom signal-processing pipelines and accelerators.
• Complex glue-logic and protocol bridging  The combination of extensive I/O and abundant logic capacity suits applications that consolidate multiple peripheral interfaces or implement protocol translation.
• Prototype and system integration platforms  The FCBGA package and surface-mount footprint allow integration into development and system-level boards for validating large-scale FPGA designs.

Unique Advantages

• Substantial logic capacity: 67,500 logic elements provide headroom for complex finite-state machines, custom datapaths, and hardware accelerators.
• On-chip memory for local buffering: Approximately 2.7 Mbits of embedded RAM reduce dependence on external memory for intermediate data storage.
• Extensive I/O flexibility: 488 I/O pins support broad external connectivity, enabling multi-channel interfaces and wide buses without extensive multiplexing.
• Documented architecture and system features: The Stratix III Device Handbook details memory blocks, DSP blocks, clocking resources, configuration and test support, aiding system-level design and verification.
• Compact production package: 780-BBGA (29 × 29 mm) surface-mount package balances pin count and board-area efficiency for commercial applications.
• Commercial-grade and compliant: Rated for 0 °C to 85 °C operation and RoHS compliant for standard commercial deployments.
