EP1S40B956C6 概要
A field-programmable gate array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs/LABs), programmable interconnects, programmable I/O cells, and dedicated hard IP such as block RAM, DSP blocks, PLLs, and high-speed transceivers. FPGAs sit at the top of the programmable logic hierarchy (below ASICs but above CPLDs) and are classified as programmable logic devices (PLDs) within the broader semiconductor category. Stratix FPGAs in particular target high-performance applications requiring embedded memory, DSP, and gigabit serial I/O.
The EP1S40B956C6 differentiates from lower-density Stratix parts through its 4,125 LABs and 46,970 CLB-equivalent register count, providing the capacity to host multi-million-gate system designs. It integrates TriMatrix memory (M512/M4K/M-RAM blocks), embedded DSP blocks, and up to twelve global clock networks with PLL support. Compared with Stratix GX variants, the EP1S40B956C6 omits dedicated gigabit transceivers, positioning it for parallel-I/O and memory-rich designs rather than serial-protocol applications.
Typical applications include high-performance digital signal processing, telecom line cards, ASIC prototyping, video and image processing pipelines, and embedded control with on-chip processors. The 956-ball BGA package and 683 user I/O pins support high-bandwidth parallel memory interfaces (DDR/DDR2) and multiple industry-standard buses. Combined with the Quartus II design toolchain, the EP1S40B956C6 enables rapid design iteration for prototyping and production deployment.
When designing with this device, pay close attention to power-plane decoupling and thermal dissipation of the FCBGA package. Use at least one 0.1 uF decoupling capacitor per power pin, distribute multiple VTT and VCCINT planes across the PCB stack-up, and verify signal-integrity simulations for high-speed DDR/DDR2 interfaces. The -6 speed grade is the slowest in the Stratix family and is typically chosen for cost-sensitive designs or for engineering prototypes.

主な用途
EP1S40B956C6 の用途: 7 件s: High-Performance Digital Signal Processing, Telecommunications Line Cards, ASIC Prototyping, Video and Image Processing Pipelines, Industrial Control and Automation, Embedded Processor Subsystems, Test and Measurement Instrumentation.
High-Performance Digital Signal Processing
The EP1S40B956C6's 41,250 logic cells and embedded DSP multiplier blocks make it a strong fit for high-performance DSP systems such as radar baseband processing, software-defined radio front-ends, and multi-channel audio/video codecs. With 4,125 LABs the device can host hundreds of parallel multiplier-accumulator engines, while the TriMatrix memory hierarchy (M512/M4K/M-RAM) keeps data close to computation for low-latency FFTs and filters. The 956-ball BGA exposes 683 user I/Os, allowing direct attachment to high-speed parallel ADCs and DACs without external muxing. Designers targeting this application should use Quartus II's DSP Builder to map math functions into dedicated DSP blocks, reserving logic cells for control and glue.
おすすめ
Telecommunications Line Cards
The 683 user I/O pins of the EP1S40B956C6 support multiple parallel telecom interfaces such as LVDS, LVPECL, and HSTL buses, enabling aggregation of OC-48/STM-16 traffic or 10 Gigabit Ethernet MAC functions in 2004-era line cards. The embedded TriMatrix memory blocks provide the per-port buffers and lookup tables required for cell/frame processing. Its multiple PLLs allow frequency synthesis for different backplane speeds (155/622 MHz) and oversampling clocks. For SONET/SDH or packet-switch fabrics the -6 speed grade is sufficient for up to ~250 MHz internal operation, while designers needing more margin select the -7 or -8 grade EP1S40B956C7/EP1S40B956C8 pin-compatible variants.
おすすめ
ASIC Prototyping
With 41,250 logic cells and abundant TriMatrix memory, the EP1S40B956C6 has historically been used to prototype ASIC RTL in FPGA form, allowing pre-silicon validation of designs destined for sub-90 nm ASIC processes. The 683 user I/O and BGA-956 footprint permit mapping wide internal ASIC buses to off-chip verification headers, JTAG, and memory buses. Quartus II's incremental compilation and LogicLock regions allow the prototype to be partitioned to mirror the planned ASIC block diagram, easing migration from prototype to silicon. Engineers use this part because it provides a balance of logic capacity, memory, and I/O - more headroom than Stratix EP1S20/EP1S25 but cheaper than the EP1S60/EP1S80.
おすすめ
Video and Image Processing Pipelines
Real-time video processing (HD-SDI, DVI/HDMI pre-processing, motion estimation, color-space conversion) benefits from the EP1S40B956C6's combination of DSP blocks, embedded multipliers, and wide on-chip memory. With 4,125 LABs the device can run multiple parallel pixel pipelines at 148.5 MHz (HD-SDI) or 165 MHz (1080p), while the M4K and M-RAM blocks store line buffers and frame contexts. The 683 user I/O balls accommodate the 24- to 48-bit wide parallel buses needed for uncompressed video plus audio and control side-channels. Camera and broadcast OEMs deployed this Stratix generation between 2002 and 2010 as a flexible DSP+control platform.
おすすめ
Industrial Control and Automation
Industrial control systems require deterministic real-time processing with extensive I/O for sensors and actuators; the EP1S40B956C6's 683 I/O and abundant LABs support multi-axis motor control, deterministic Ethernet (EtherCAT, PROFINET), and high-speed ADC interfacing. Industrial-grade variants like EP1S40B956I6 extend the operating range to -40C to 100C, supporting factory-floor deployments. The device's multiple PLLs enable synchronization of multiple motors or generators, and its embedded memory allows real-time buffering of high-speed ADC samples. This makes the part suitable for servo drives, programmable logic controllers (PLCs), and machine vision inspection systems.
おすすめ
Embedded Processor Subsystems
The EP1S40B956C6 can host soft-core processors (Altera Nios II, MicroBlaze-equivalent) alongside custom hardware accelerators, enabling an SoC-style design within a single FPGA. The 41,250 cells comfortably fit a Nios II/f core plus peripherals, on-chip memory, and a hardware accelerator block for cryptographic, signal-processing, or networking workloads. External memory interfaces (DDR/DDR2 SDRAM controllers) are supported through dedicated PHY blocks and the high I/O count of the BGA-956. This makes the part a flexible platform for embedded computing in test equipment, network appliances, and industrial gateways.
おすすめ
Test and Measurement Instrumentation
Test instruments such as logic analyzers, protocol analyzers, and arbitrary waveform generators rely on the EP1S40B956C6's combination of high logic capacity and very wide parallel I/O to capture or generate hundreds of signals simultaneously. The TriMatrix memory and embedded DSP blocks allow real-time pattern matching, Fast Fourier Transform analysis, and digital signal synthesis in a single device. Its 683 I/O support direct attachment to high-pin-count probe fixtures, and the 1.5 V core with multiple I/O standards (LVTTL, LVCMOS, SSTL, HSTL) enables interfacing with both modern and legacy DUTs. The -6 speed grade is appropriate for instrumentation up to ~250 MHz state rates.

主な差別化要因
- Highest-density member of the original Stratix family in BGA-956 （vs EP1S30B956C6)
- Wide selection of pin-compatible speed and temperature grades （vs EP1S40B956C6N (RoHS) and EP1S40B956C7 (faster))
- Mature Quartus II toolchain support （vs ASIC at similar capacity)
設計ノート
The 40 x 40 mm BGA-956 package concentrates thermal output across a large footprint; engineers should estimate FPGA junction temperature using the Altera PowerPlay early-power estimator (typical Stratix -6 grade devices dissipate 3-8 W depending on toggle rate and block utilization). For high-utilization designs consider a 4-layer PCB with a ground plane directly beneath the BGA, thermal vias under the die flag, and a low-profile heatsink if junction-to-ambient exceeds 60C. Industrial-temperature EP1S40B956I6 variants extend to -40C to 100C for harsh environments.
Escape the 1.27 mm pitch BGA-956 grid using a 4-2-4-2-4 microvia stack-up on a high-Tg FR-4 or low-loss PCB substrate. Each BGA ball requires a fanout via, so plan at least 8 inner signal layers for the escape plus dedicated VCCINT, VCCIO, and GND planes. Length-match DDR/DDR2 interfaces within +/-25 ps and use 50-ohm controlled-impedance traces for HSTL/SSTL. Decouple each power pin with 0.1 uF X7R ceramic caps placed as close to the ball as possible.
Because the part is NRND, confirm with the Intel/Altera Product Discontinuance notices that the EP1S40B956C6 is still orderable and not in last-time-buy status before committing to a long-life program. For new designs, migrate to a current-generation Stratix II, III, IV, V, or Stratix 10 device. When upgrading to the EP1S40B956C7 or EP1S40B956C8 (faster speed grades), re-run timing analysis - higher speed grades relax setup slack but do not change pinout or power requirements.
Place JTAG chain components (TCK/TMS/TDO/TDI pull-ups and the 4.7 kohm series resistors) within 25 mm of the configuration balls to avoid signal integrity issues. The configuration clock DCLK and data lines DATA[7:0] must be length-matched to within 100 mils if running at >50 MHz for fast passive serial configuration. For multi-device JTAG chains, add 33-ohm series damping resistors near each device's TDO output.
