EP2C70F896C8N 概要
A Field-Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing, sitting within the broader hierarchy of programmable logic devices (PLD) → FPGA → digital semiconductor → integrated circuit. The Cyclone II family was architected to deliver ASIC-like density at ASIC-competitive pricing, displacing gate arrays in cost-sensitive volume applications such as consumer electronics, industrial control, and communications infrastructure.
Key features include up to 250 MHz internal operation, dedicated DSP blocks for high-speed multiply-accumulate operations, and Cyclone II's signature low-power architecture that consumes 50 percent less dynamic power than its Cyclone predecessor. The device also offers up to four PLLs for clock management, supporting frequency synthesis, phase shifting, and zero-delay buffering. The 896-FBGA package supports high-density board designs with extensive I/O access while maintaining a compact 31 mm x 31 mm footprint.
The EP2C70F896C8N utilizes a SRAM-based configuration cell with on-chip configuration memory, requiring an external configuration device such as the EPCS16 or EPCS64 serial flash for standalone operation. Cyclone II devices support the Quartus II design software (version 13.0 and later recommended for legacy support), with IP libraries for DDR/DDR2 SDRAM controllers, PCI, PCI Express, and Ethernet MAC functions. The 90 nm process node and 1.2 V core voltage deliver an optimal balance of performance and power consumption for cost-optimized designs.
Typical applications include video processing and display controllers, industrial Ethernet and fieldbus gateways, motor control and servo drives, low-cost software-defined radio front-ends, and ASIC prototyping for mid-complexity designs. The 622 available user I/Os and 150 DSP blocks make it well-suited for parallel signal processing tasks such as image filtering and digital pre-distortion.
When designing with this device, ensure that the configuration scheme is selected before PCB layout, since the dual-purpose configuration pins differ across AS, PS, and JTAG modes. The 896-FBGA package requires microvia-compatible PCB fabrication and careful power-plane segmentation to maintain signal integrity at 250 MHz.

Its 250 MHz core frequency and 150 dedicated multipliers provide deterministic MAC-layer processing with hardware-accelerated CRC and frame stamping, while the 622 I/Os can host multiple isolated PHY interfaces, RS-485 transceivers, and CAN controllers concurrently. The commercial 0C to +85C temperature range suits factory-floor enclosures with active cooling. For harsh industrial environments, the industrial-temperature EP2C70F896I8N variant delivers -40C to +100C operation in the same package.
おすすめ
Motor Control and Servo Drives
In multi-axis servo drives and AC induction motor controllers, the EP2C70F896C8N provides the FPGA fabric for parallel current-loop control of up to six axes. The 150 embedded 18x18 multipliers execute Park/Clarke transforms and space-vector PWM at sub-microsecond latency, while 4 PLLs generate the precisely-phased carrier frequencies for IGBT gate drivers. The 622 I/Os handle quadrature encoder inputs, Hall-effect sensors, and PWM outputs without external logic. Compared to a DSP+ASIC solution, this Cyclone II design consolidates the control loop, communication stack (EtherCAT/CAN), and safety logic on one device, reducing BOM and PCB complexity.

設計ノート
The EP2C70F896C8N requires a 1.2 V core supply and a 3.3 V I/O supply, plus a 2.5 V analog PLL supply (VCCA_PLL) for the 4 PLLs. Cyclone II power sequencing requires core voltage to ramp before I/O voltage to avoid I/O latch-up; use a supervisor IC such as the TPS3808 to enforce sequencing. Estimated: at 250 MHz with 80% logic utilization, the device draws approximately 1.0-1.5 A from VCCINT and 0.5-1.0 A from VCCIO. Decouple each VCCINT pin with a 0.1 uF X7R ceramic plus a 10 uF bulk capacitor.
The 896-FBGA uses a 1.0 mm ball pitch with 31 mm x 31 mm body. PCB fabrication must support microvia (laser-drilled) stack-up with minimum 4-6 routing layers to fan out from the inner ball grid. Match all differential pairs to 100 ohm impedance and all single-ended I/O to 50 ohm controlled impedance. Maintain continuous ground planes beneath the device and stitch vias around the BGA perimeter to suppress ground bounce.
The EP2C70F896C8N requires an external configuration memory such as EPCS16, EPCS64, or EPCQ16 for standalone operation. Select configuration mode (AS, PS, or JTAG) via MSEL pins at PCB design time - the choice is not reversible without board rework. For in-system reprogramming, expose the JTAG pins (TCK, TMS, TDI, TDO) to a 10-pin header compatible with the Altera USB-Blaster or Intel FPGA Download Cable.
Common pitfalls include: (1) leaving MSEL pins floating instead of tying to known state; (2) forgetting to enable nCONFIG pull-up; (3) using 2.5 V LVCMOS on I/O banks without checking VCCIO bank voltage; (4) not providing a clean 2.5 V analog PLL supply; (5) designing DDR interfaces without using the dedicated DQS/DQSn pins for byte-level alignment; (6) not running Quartus II TimeQuest timing analysis before board fabrication.
Estimated: at 250 MHz internal operation, source-synchronous interfaces such as DDR SDRAM and LVDS require length-matched traces within 25 mils (0.635 mm) across the byte group. Use series termination resistors on high-speed outputs and minimize via stubs. For DDR2 SDRAM up to 200 MHz, enable Cyclone II's on-chip dynamic phase alignment (DPA) circuitry to ease timing constraints.
