MPN: EP3SE50F780C2G ⚠ Huling PagbiliEP3SE50F780C2G Ulas
A Field Programmable Gate Array (FPGA) is a type of integrated circuit containing an array of programmable logic blocks, configurable interconnect, and on-chip memory that can be customized after manufacturing to implement virtually any digital logic function. FPGAs occupy the position of programmable logic devices (PLD) within the broader semiconductor hierarchy: PLD -> ASIC family -> logic ICs -> integrated circuits. Stratix III E FPGAs specifically target DSP and high-throughput memory-intensive workloads with dedicated DSP blocks, embedded TriMatrix memory blocks, and high-speed transceivers.
Key features of the EP3SE50F780C2G include 47,500 logic elements, 1,900 Logic Array Blocks (LABs), 5.49 Mbit embedded RAM, 488 maximum user I/Os, and 132 embedded 18x18 multipliers. The device integrates up to 12 embedded transceivers (depending on variant) supporting data rates up to 3.75 Gbps for serial connectivity, and supports DDR2/DDR3 memory interfaces at speeds up to 800 MHz. The C2 speed grade indicates commercial temperature range (0C to +85C) with a moderate timing closure rating.
The device's 65 nm low-k process technology and adaptive logic modules (ALMs) deliver a balanced ratio of register-rich to combinational logic, enabling efficient pipelined DSP and parallel datapath designs. Programmable Power Technology allows unused blocks to be powered down, reducing static consumption relative to comparable fixed-logic architectures.
Typical applications include high-end ASIC prototyping, wireless baseband processing, high-definition video processing, military radar signal chains, and test & measurement equipment. The 780-ball FCBGA package supports high-density board designs where multi-gigabit transceivers and large memory bandwidth are required. The EP3SE50F780C2G is best suited for designs that can fully exploit its DSP blocks and high pin count rather than simple glue-logic applications where a smaller Cyclone device would be more cost-effective.
When designing with this part, ensure adequate thermal management for the FCBGA package - a minimum of four PCB layers with thermal vias under the device is recommended. Quartus II design software is required for synthesis, place-and-route, and bitstream generation; the Quartus Prime Lite edition does not support Stratix III and the Quartus II Subscription Edition is required for the final timing closure and programming files.

Talaan ng Disenyo
The 780-FCBGA package requires careful thermal management. Estimated: with 100% logic utilization at typical toggle rates (~20%), core power reaches 4-6 W. A minimum 4-layer PCB with continuous ground/power planes beneath the device and a thermal-via array (0.3 mm pitch, 0.2 mm drill) connecting top-side pad to internal copper is required to keep junction below 125C. Active airflow or a heatsink is recommended for sustained workloads.
Use 1.0 mm ball pitch land pattern per JEDEC MS-034 for the 780-FCBGA. Decouple each VCC/VCCPD/VCCPGM pin with a 0.1 uF X7R ceramic placed as close as possible. Add 10 uF bulk capacitors within 1 cm of the device. Match differential pair lengths within 0.13 mm (5 mil) for LVDS signals and within 0.05 mm (2 mil) for transceiver channels. Route high-speed transceivers on the top layer only with a continuous reference plane.
Do not assume Quartus Prime Lite supports this device - Stratix III requires the Quartus II Subscription Edition. Confusing speed grades (C2 vs C3 vs C4) when ordering can leave 10-30% timing margin on the table. The 'G' suffix indicates lead-free RoHS-compliant ball finish; the non-G variant is SnPb. Verify I/O bank voltage assignments match your mixed-voltage design before committing to PCB layout, as bank re-assignment is not possible post-fab.
