Verified distributor data identifies a 437.5 MHz maximum clock, 1.2 V supply, 65 nm process technology, and a commercial temperature grade. The device is listed for sale by DigiKey and Mouser, while the verified search snapshot reports same-day shipping from DigiKey. An FPGA is a programmable semiconductor whose logic, interconnects, and I/O behavior can be configured after manufacturing. Within the component hierarchy, it belongs to programmable logic devices and field-programmable gate arrays. Unlike a fixed-function application-specific integrated circuit, an FPGA supports iterative logic changes without fabricating a new integrated circuit, making it useful for digital design, prototyping, interface bridging, and configurable control systems. The headline resources are 81,264 cells, 2,810,880 embedded-memory bits, and 295 I/O. These resources support datapaths, state machines, communications controllers, and peripheral interfaces. The 437.5 MHz value represents a verified maximum-clock listing and should be interpreted within the device's stated configuration and operating conditions. The 1.2 V core supply reflects the listed Cyclone III architecture. The part uses a 65 nm process and is supplied in a rectangular 484-terminal FBGA, also identified as UBGA or BGA-484 by distributor and comparison sources. The high terminal count supports 295 user I/O plus dedicated power, configuration, clock, and other device functions. Surface-mount assembly, controlled-impedance routing, and appropriate decoupling are therefore central to reliable implementation. Typical applications include industrial control, communications equipment, video or imaging interfaces, test equipment, and embedded processing systems. Its logic capacity suits multiple control blocks and interface functions, while the large I/O count helps connect memories, converters, network transceivers, and application-specific peripherals. Engineers must confirm timing closure, configuration storage, power sequencing, and supported I/O standards in the manufacturer datasheet. A key design trade-off is that adding programmable logic does not remove implementation effort. Clock budgets, pin assignments, power integrity, signal integrity, and thermal behavior must be analyzed for the final design. Logic capacity and I/O count alone do not guarantee a particular maximum system clock, because routing, constraints, tool settings, and peripheral interfaces affect timing. This page consolidates the verified distributor specifications, commercial availability, package identity, datasheet location, applications, and cross-reference evidence. Because no verified five-item set of same-footprint, pin-to-pin FPGA replacements was provided, alternatives are limited to candidates that can be supported without fabricating cross-brand or cross-package claims.

Cyclone III LS adds additional security features such as configuration bitstream encryption and JTAG-based tamper protection, distinguishing it from the standard Cyclone III family. Key features of the EP3CLS100F484C7N include a logic element count of 100,448 (giving roughly 100K LE), 4,451,328 bits (~4.4 Mbit) of embedded SRAM organized into M9K blocks, embedded 18x18 multipliers for DSP operations, and four general-purpose PLLs per device for clock management. The 'F484' suffix denotes the 484-pin FineLine BGA package, 'C7' denotes the commercial speed grade 7, and 'N' indicates lead-free / RoHS compliance. Compared with the older Cyclone II family, Cyclone III LS cuts core voltage to 1.2 V and adds security features while retaining the low-cost positioning that the family is known for. Typical applications include industrial motor control, video processing pipelines, software-defined radio front ends, automotive infotainment (where the LS security features matter), test and measurement equipment, and low-cost protocol bridging. Designers choose this part when they need >100K LE of logic plus DSP blocks in a BGA that can be assembled with standard 1.0 mm-pitch PCB processes. The device is supported by Quartus II (and later Intel Quartus Prime) design software, which provides synthesis, place-and-route, timing analysis, and bitstream generation. When designing with this part, plan for the 484-ball FBGA land pattern carefully - the package uses 1.0 mm ball pitch and requires microvia or via-in-pad PCB technology for reliable assembly. Decoupling follows the Cyclone III LS Hardware Reference manual recommendations with multiple bulk and high-frequency caps across the 1.2 V core and each bank VCCIO rail. Finally, designers must provision a configuration source (EPCS serial flash, JTAG, or parallel flash) because the SRAM-based configuration memory is volatile.

EP3CLS100F484C8 - Cyclone III LS FPGA | Altera / Intel
The Altera EP3CLS100F484C8 is a Cyclone III LS field-programmable gate array (FPGA) with 100,448 logic elements, 4,451,328 RAM bits, and 278 user I/O pins, supplied in a 484-ball FBGA package. This commercial-temperature, speed-grade-8 device operates from a 1.2V core supply and is part of the low-power Cyclone III LS family built on a 65nm process. An FPGA is a semiconductor device whose logic fabric and interconnects are reconfigured by the user after manufacturing. FPGAs occupy the programmable-logic portion of the integrated circuit hierarchy: FPGA -> programmable logic device -> integrated circuit. Unlike ASICs, they can be updated in the field, which makes them useful for prototyping, low-to-medium production, and systems where standards change quickly. The EP3CLS100F484C8 is the 100,000-logic-element-class member of the Cyclone III LS series, designed for applications that need high logic density without the cost or power of an ASIC. Key features include 100,448 logic elements, 4,451,328 RAM bits, and 278 user I/Os. The device is a commercial-grade part in the Altera/Intel ordering code, where C indicates commercial temperature and 8 indicates speed grade 8. According to distributor and cross-reference data, the FPGA is built on a 65nm process and is rated for 1.2V core operation, with an FPGA performance indicator of 402MHz in the Cyclone III LS family. The 484-ball FBGA package provides enough pins for wide memory buses and many parallel I/O channels. The Cyclone III LS family is distinguished from the standard Cyclone III family by lower power and the LS security-related features; the exact feature set and I/O standard support are defined in the Cyclone III and Cyclone III LS device handbooks. From a system perspective, the EP3CLS100F484C8 provides a reconfigurable parallel computing fabric that can implement RTL logic, soft processors, DSP datapaths, and state-machine controllers in one device. It requires an external configuration device or JTAG download at power-up because it is SRAM-based. Typical applications for this FPGA include industrial motor control and factory automation, networking and Ethernet bridging, machine vision and video processing, medical imaging equipment, high-performance test-and-measurement instruments, and compute/network acceleration. The high I/O count and 100K logic capacity allow designers to integrate multiple discretely implemented functions onto one programmable platform, reducing total system component count. A key design consideration is that the EP3CLS100F484C8 requires a clean 1.2V core supply and correct power-up configuration sequencing. Use a serial configuration device such as the EPCS or EPCQ family, or download the bitstream through JTAG during development. Thermal dissipation from an FPGA this size also requires proper BGA layout, sufficient copper planes, and air flow in the final enclosure.

Typical applications for this part include industrial motor control, video processing pipelines, software-defined radio front-ends, factory automation controllers, low-cost PCIe protocol bridges, and portable medical instrumentation where low static power and tamper resistance are both required. The 484-ball BGA package supports the device's full I/O count while keeping the board footprint manageable for multilayer PCBs. When designing with this FPGA, use the Quartus II (or Quartus Prime) toolchain to generate configuration bitstreams; the LS device family must be selected explicitly to enable the AES encryption engine. Plan power sequencing carefully because the Cyclone III LS family requires 1.2 V core, 2.5 V analog, and 3.3 V I/O rails with a documented power-on-reset order. Decoupling must follow the reference board's recommendations because the PLLs and serializer/deserializer blocks are sensitive to supply noise.

EP3CLS100U484C7 - Cyclone III LS FPGA 100K LE UFBGA-484
The Altera (Intel) EP3CLS100U484C7 is a low-power Cyclone III LS Field Programmable Gate Array (FPGA) built on a 65 nm CMOS process, integrating 100,448 logic elements in a 484-ball Ultra-FineLine BGA (UFBGA) package with 0.8 mm pitch and a 19 x 19 mm body. It belongs to the Cyclone III LS sub-family, which adds hardware AES bitstream encryption and a robust configuration infrastructure to the standard Cyclone III architecture. An FPGA (Field Programmable Gate Array) is a programmable logic device (PLD) that sits in the broader semiconductor hierarchy between application-specific integrated circuits (ASICs) and microcontrollers. It is composed of configurable logic blocks (CLBs), programmable interconnect, embedded memory blocks (M9K/M144K), embedded multipliers, and I/O elements (IOEs). FPGAs are used when designers need custom parallel hardware, deterministic latency, or hardware-accelerated signal processing without the NRE cost of an ASIC. Key features of the EP3CLS100U484C7 include 100,448 logic elements, 4,451,328 bits of embedded RAM (approximately 4.2 Mbit), 278 user I/O pins, embedded 18x18 multipliers for DSP, and a core voltage of 1.2 V. The Cyclone III LS family adds 256-bit AES encryption for bitstream protection, JTAG-based configuration, and supports multiple configuration schemes including active serial, passive serial, and fast passive parallel modes. The device architecture combines 4-input LUT-based logic elements, True Dual-Port RAM blocks, and dedicated PLL blocks for clock synthesis. The 65 nm process enables a favorable power/performance ratio, making the LS sub-family suitable for power-sensitive applications where standard Cyclone III logic density is needed but bitstream security is also required. Maximum internal clock frequencies around 437-450 MHz support a wide range of digital signal processing pipelines. Typical applications include industrial motor control, video processing and display interfaces, automotive driver-assistance subsystems, secure communications equipment, software-defined radio (SDR) baseband, and portable medical instrumentation. The 278 available user I/O enables direct interface to DDR/DDR2 memory, LVDS signaling, and a wide mix of legacy parallel buses. When designing with this device, careful attention must be paid to decoupling, the multi-rail power sequencing (1.2 V core, 2.5 V/3.3 V analog and I/O), and configuration mode selection at board bring-up. Engineers should use Altera/Intel Quartus II design software for synthesis, place-and-route, and bitstream generation; configuration file generation requires the design license tier matching the device family.

EP3CLS100U484C7N - Cyclone III LS FPGA, 100K LE, 484-FBGA | Altera
The Intel (formerly Altera) EP3CLS100U484C7N is a Cyclone III LS family Field Programmable Gate Array (FPGA) IC delivering 100,448 logic elements and 4,451,328 bits of embedded memory in a 484-ball Fine-pitch Ball Grid Array (FBGA) package with 278 user I/O pins. The device is fabricated on a low-power 65 nm TSMC process and operates from a 1.2V core supply, with the speed grade -7 (commercial) and a maximum internal clock frequency of 437.5 MHz per the manufacturer datasheet family. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by a programmable interconnect and surrounded by programmable I/O cells. Modern FPGAs embed hard IP such as block RAM, DSP blocks, PLLs, and high-speed transceivers, allowing a single chip to implement complete digital signal-processing pipelines, glue logic, or even soft processor subsystems. Cyclone III LS belongs to Intel's low-power, low-cost FPGA family that sits beneath the Stratix series in the product hierarchy: FPGA -> low-cost FPGA -> Cyclone family -> Cyclone III -> Cyclone III LS (lower static power, targeted at power-sensitive applications). The 'LS' suffix indicates reduced-leakage silicon compared to standard Cyclone III, with lower static power at the cost of slightly lower maximum operating frequency. Key features of the EP3CLS100U484C7N include 100,448 logic elements, 4,451,328 embedded memory bits (approximately 4.4 Mbits), dedicated 18x18 hardware multipliers for DSP, multiple phase-locked loops (PLLs) for clock management, and a 484-pin FBGA package that supports up to 278 general-purpose I/O pins spread across eight I/O banks. The 65 nm process and 1.2 V core voltage yield low static and dynamic power consumption relative to older 90 nm and 130 nm FPGA generations. Architecturally, the Cyclone III LS device uses an SRAM-based configuration cell that is loaded from an external flash or configuration controller at power-up. Logic is implemented in Look-Up Tables (LUTs), DSP operations in dedicated multiplier blocks, and on-chip memory in M9K blocks (9 Kbits each). The integrated PLLs synthesize multiple clock domains from a small number of reference oscillators, and the I/O structure supports a wide range of single-ended and differential signaling standards (LVDS, SSTL, HSTL, LVCMOS, LVTTL, PCI, PCI-X). Typical applications include industrial motor control and factory automation, video processing and display controllers, low-cost software-defined radio front-ends, embedded vision and machine-vision preprocessing, telecommunications line cards and protocol bridging, medical imaging front-ends, automotive driver-assistance subsystems, and educational/hobbyist development platforms such as the Altera/Intel DE0/DE2-115 boards. The combination of 100K logic elements, 278 user I/Os, and low 1.2 V core power makes the part well suited for medium-complexity parallel-processing tasks that would be too large for a CPLD yet do not justify a high-cost Stratix device. When designing with this part, the engineer should plan the configuration scheme (AS, AP, PS, or JTAG), select appropriate decoupling for the 1.2 V core and the bank I/O supplies (typically 1.5 V, 1.8 V, 2.5 V, 3.3 V), and budget thermal dissipation. Although the 65 nm LS silicon is low-power, a fully utilized 100K-LE device with high toggle rates can still dissipate several watts; a small thermal pad or copper pour is recommended on the BGA land pattern.
