EP3SL70F780I4N 개요
A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hardware resources such as block RAM, DSP slices, PLLs, and high-speed I/O serializers. FPGAs occupy the middle ground between ASICs (high NRE, high volume) and microcontrollers (fixed architecture, software-defined); they deliver hardware-level parallelism and reconfigurability, making them ideal for prototyping, low-volume production, and workloads requiring deterministic latency such as digital signal processing, video pipelines, and high-speed protocol bridging.
Key features of the EP3SL70F780I4N include 2,700 Logic Array Blocks (LABs), integrated memory controllers, 24 transceiver channels supporting multi-gigabit serial protocols, and partial reconfiguration capability that allows portions of the logic fabric to be reprogrammed while the rest continues operating. The device supports industrial-grade operating conditions (-40C to +100C junction) and uses Altera's Quartus II design suite for synthesis, place-and-route, and timing closure.
Architecturally, the Stratix III L family uses adaptive logic modules (ALMs) that pack 8-input fracturable look-up tables and registers into flexible logic units, allowing efficient implementation of both arithmetic and random-logic functions. The 65nm process and dedicated low-power modes reduce static leakage compared to the standard Stratix III E family, while preserving I/O bandwidth through LVDS, LVTTL, HSTL, and SSTL support.
Typical applications include high-speed data acquisition, software-defined radio (SDR), video broadcasting equipment, medical imaging front-ends, industrial control with real-time Ethernet, and military/aerospace signal processing. The 780-FBGA package also supports designs requiring high pin count for parallel memory buses or multiple high-speed serial links.
Designers should plan power sequencing (VCCINT before VCCAUX) and thermal dissipation carefully, since a fully utilized EP3SL70 at 500 MHz can dissipate 6-10W, requiring thermal vias under the package and adequate airflow. Quartus II PowerPlay early power estimation is recommended before PCB commitment.

설계 노트
Estimated: A fully utilized EP3SL70F780I4N at 500 MHz with high toggle rates can dissipate 6-10 W. The 1.1V VCCINT rail must supply up to 5 A with less than 30 mV peak-to-peak ripple - use a buck converter with at least 20% current headroom (e.g., 6 A rated) and bulk-decoupling of 4x 220 uF polymer plus 20x 100 nF ceramics near the package. Power sequencing (VCCINT before VCCAUX, VCCAUX before VCCIO) is mandatory to prevent latch-up; use a sequencer IC such as the LM3880 or TPS3808.
The 780-FBGA has a typical theta_JB of 4 C/W; with a 7 W dissipation, junction-to-board temperature rise is ~28C. Design PCB with a full thermal-via array (0.3 mm pitch) under the package center connected to internal copper planes; for ambient > 60C or chassis-mounted applications, attach a heatsink with thermal interface material. Quartus II PowerPlay early power estimator should be run with realistic toggle rates before layout commitment.
Use 1.0 mm ball pitch BGA fanout with microvia-in-pad or 8-mil dogbone escape routing. Maintain 100-ohm differential impedance for LVDS pairs (typical 4-mil/8-mil stripline in 0.2 mm stackup). Split ground planes: digital ground for I/O banks and transceivers, analog ground for PLL/JTAG; join at a single point under the package. Match length within 25 mils for high-speed LVDS groups.
Do not use EP3SL70F780I4N for new designs - it is NRND; consider Stratix V (5SGXEA7) or Cyclone V (5CEFA7) instead, but note these require different packages. When migrating a design, re-run timing closure since architecture differences between L and E variants affect DSP block inference. JTAG chain ordering matters: place the EP3SL70 first in the chain for boundary-scan bring-up. Always validate configuration mode (AS, PS, FPP, JTAG) using the actual EPCS/EPCQ flash part number shipped, not the generic Quartus assignment.
Transceiver channels require AC-coupled differential routing with characteristic impedance of 85-100 ohms; reference plane continuity is critical across the entire channel. Place AC-coupling capacitors (10 nF X7R) within 100 mils of the receiver pins. For LVDS inputs at > 600 Mbps, add a 100-ohm differential source termination at the FPGA pin side. Use IBIS or HSpice simulation for critical interfaces, since the Quartus II Fitter does not model transmission-line effects.
