EP3CLS100U484I7 Обзор

The Intel (formerly Altera) EP3CLS100U484I7 is a low-power Cyclone III LS Field Programmable Gate Array with 100,448 logic elements, 4,451,328 bits of embedded memory, and 278 user I/O pins, housed in a 484-ball FineLine BGA (UBGA) package. It is fabricated on TSMC's 60 nm low-power process and operates from a 1.2 V core supply with industrial temperature range support.

A Field Programmable Gate Array (FPGA) is a programmable logic device consisting of an array of configurable logic blocks (CLBs), programmable interconnect, and embedded hard IP such as block RAM, DSP blocks, and PLLs. FPGAs sit within the broader category of programmable logic devices (PLDs) under the digital semiconductor hierarchy, offering parallel hardware processing flexibility that microcontrollers and DSPs cannot match. The Cyclone III LS family specifically targets low-static-power designs where battery life or thermal dissipation is critical.

Key features of the EP3CLS100U484I7 include 100,448 logic elements, 4,451,328 total RAM bits distributed across M9K memory blocks, 66 embedded 18x18 multipliers, 4 PLLs, and 278 maximum user I/O pins. The device supports LVDS, LVCMOS, SSTL, and HSTL I/O standards with hot-socketing capability. Industrial temperature grade (I7 suffix, -40C to +100C junction) makes it suitable for harsh environment deployments.

Cyclone III LS devices employ a fine-grained 8-input adaptive logic module (ALM) architecture that improves logic packing efficiency versus the 4-input LUT architecture of older Cyclone families. The dedicated 18x18 multiplier blocks enable cost-effective DSP workloads such as FIR filters and FFT engines without consuming general-purpose logic. Configuration is via active serial (AS), passive serial (PS), fast passive parallel (FPP), or JTAG modes using industry-standard 16-64 Mbit EPCS or EPCQ configuration memories.

Typical applications include industrial motor control, factory automation HMIs, portable medical imaging, video surveillance with on-chip buffering, low-power wireless baseband processing, and military/aerospace signal processing. The 484-UBGA package with 1.0 mm ball pitch is footprint-compatible across the Cyclone III family (EP3C25 through EP3C120 in the same package), enabling migration paths as designs scale.

When designing with this FPGA, pay close attention to power planning: Cyclone III LS offers PowerPlay early power estimation tools that should be run after RTL coding and before PCB layout to size decoupling budgets. The 484-UBGA package requires 4-6 layer PCB stackup with 1.0 mm pitch escape routing; signal integrity simulations are recommended for DDR2/3 memory interfaces running above 200 MHz.

This page synthesizes distributor inventory, footprint-compatible same-package alternatives, and practical power/thermal design notes not consolidated on the manufacturer datasheet.

Типичное применение

EP3CLS100U484I7 подходит для 6 применениеs: Industrial Motor Control, Video Surveillance & Image Processing, Portable Medical Imaging, Low-Power Wireless Baseband, Aerospace & Defense Signal Processing, Factory Automation HMI.

🏭

Industrial Motor Control

The EP3CLS100U484I7 fits industrial motor control designs because its 66 dedicated 18x18 multipliers accelerate Field-Oriented Control (FOC) math (Clarke/Park transforms, PID loops, SVPWM generation), and the 100,448 logic elements host the state machine and protection logic. The 4 PLLs generate the PWM switching frequencies (typically 10-20 kHz) and resolver-excitation sinusoids from a single 50 MHz crystal. Industrial temperature grade (I7) supports -40C to +100C operation in cabinet-less deployments. The 278 user I/O pins accept quadrature encoder inputs, Hall sensors, and drive multiple PWM channels. Estimated: power dissipation for a typical FOC firmware workload is ~1.2 W with PowerPlay optimization, manageable with a 4-layer PCB copper pour without forced cooling.

Both share the same Cyclone III LS die and 100,448 logic elements. They are NOT footprint-compatible; the choice depends on PCB stackup constraints and routing density.

EP3CLS100U484I7 vs EP3C120F484I7N - which is better for high-logic designs?

The EP3C120F484I7N (Cyclone III, non-LS) contains 119,088 logic elements versus 100,448 for the EP3CLS100U484I7, but the LS variant offers substantially lower static power. For battery-powered or thermally constrained designs, choose EP3CLS100U484I7; for maximum logic density with adequate cooling, choose EP3C120F484I7N.

Choose Cyclone IV E (e.g. EP4CE115F29) when you need higher performance, more logic, and modern 1.0 V core operation. Cyclone III LS remains preferred for designs already in production due to mature Quartus II tool support and proven long-term availability.

Can EP3C55U484I7N be a drop-in replacement for EP3CLS100U484I7?

Yes - the EP3C55U484I7N shares the 484-UBGA footprint and pinout with EP3CLS100U484I7, making it a true drop-in alternative. However, it has only 55,856 logic elements versus 100,448 (-44%), so existing designs must fit within the smaller logic budget. Suitable when migrating down to save cost or power, not as a full functional replacement.

Where to download EP3CLS100U484I7 datasheet PDF?

The official Cyclone III LS datasheet is hosted by Intel at https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyc3/cyc3_cii51006.pdf. The handbook is split into Chapter 1 (Cyclone III) and Chapter 2 (Cyclone III LS); pinout, timing, and electrical specifications for the U484 package are in the LS chapter. Registration is not required.

Where to find EP3CLS100U484I7 pinout information?

The complete 484-ball pinout for EP3CLS100U484I7 is published in the Cyclone III LS Device Handbook (chapter 2, pin tables section). Banks 1-8 are arranged around the die with dedicated PLL, configuration, and clock pins. The Intel Pin Planner tool in Quartus II automatically assigns pins based on the selected U484 package; an exportable CSV pinout is available there.

What are the key specifications of EP3CLS100U484I7 that engineers should know?

Critical specifications: 100,448 logic elements, 4,451,328 bits embedded RAM (333 M9K blocks), 66 dedicated 18x18 multipliers, 4 PLLs, 278 user I/O pins, 484-ball UBGA package, 1.2 V core supply, -40C to +100C junction temperature. Configuration supports AS, PS, FPP, and JTAG modes. Source: Cyclone III LS Device Handbook, Intel Programmable Solutions Group.

Is EP3CLS100U484I7 the same as EP3CLS100F484I7?

No. The U484 (UBGA, 19x19 mm, 1.0 mm pitch) and F484 (FBGA, smaller body) packages are NOT pin-compatible. Both parts contain the same Cyclone III LS die with 100,448 logic elements, but their ball maps differ. Verify the package code carefully when ordering - confusing U and F suffixes is a common sourcing error that requires full PCB rework.

Руководство по выбору

Choose EP3CLS100U484I7 when your design needs mid-range logic capacity (100K LE) with low static power (Cyclone III LS family) and industrial temperature operation. This part is optimal for battery-powered or fanless embedded systems running always-on DSP workloads. Choose EP3C120U484I7N if you need +18% more logic and accept higher static current. Choose EP3C55U484I7N or EP3C40U484I7N when cost-down is critical and your design fits within 56K or 40K LE. All four parts share the identical 484-UBGA footprint, so PCB layout is reusable across the entire family range - only the FPGA bitstream and Quartus project target need to change.

Заметки по проектированию

Run Intel PowerPlay early power estimation after RTL coding and before PCB layout. Cyclone III LS static current is markedly lower than Cyclone III non-LS; however, dynamic power scales with toggle rate. Decoupling: place 0.1 uF X7R ceramics adjacent to every VCCINT pin and bulk 100 uF tantalum or polymer at board entry. VCCIO banks must each have their own 0.1 uF + 4.7 uF capacitor pair.

At typical 1.2 W core dissipation (PowerPlay estimate) the 484-UBGA requires no external heatsink on a 4-layer PCB with 1 oz copper pours. At 2 W+ sustained load, add thermal vias under the central GND balls and a 25x25 mm top-side copper flood. Industrial grade is junction-rated to +100C; recommended Tj_max operating ceiling is +85C for 7-year reliability targets.

484-UBGA at 1.0 mm pitch requires 4-6 layer PCB stackup with microvia or via-in-pad for the inner rows. Escape routing on the outermost rows uses 0.20 mm (8 mil) trace/space; inner rows need 0.15 mm (6 mil) or laser microvias. Maintain continuous GND plane beneath the BGA to control return paths for LVDS and DDR2/3 interfaces.

Do not confuse U484 (UBGA, 19x19 mm, 1.0 mm pitch) with F484 (FBGA, 23x23 mm, 1.0 mm pitch) package suffixes - they are NOT footprint-compatible. Also verify JTAG chain order and TCK frequency (max 33 MHz) before board bring-up. MSL3 moisture sensitivity mandates dry-pack bake (125C, 24 hours) before reflow if the seal is broken more than 168 hours.
