LFE2-12E-7F256C - 12K LUT 420 MHz ECP2 FPGA | Lattice

Lattice Semiconductor LFE2-12E-7F256C is an ECP2 field-programmable gate array with 12,000 logic cells, 193 I/O, a 420 MHz maximum operating frequency, and a 256-pin FPBGA package. The device operates from a 1.2 V core supply and is manufactured using a 90 nm process. Its combination of programmable logic resources, 193 user I/O, and a 17 x 17 mm package makes it suitable for embedded control, communications, interface bridging, and general-purpose logic consolidation. An FPGA is a reconfigurable semiconductor that changes its digital behavior after programming. Within the device hierarchy, the LFE2-12E-7F256C is a field-programmable gate array, an FPGA, and a programmable logic device. Unlike fixed-function logic, an FPGA can implement multiple control, interface, timing, or data-processing functions in one device and be updated during a product lifecycle. The ECP2 family provides 12,000 logic cells for moderate-complexity designs. At a maximum operating frequency of 420 MHz, the LFE2-12E-7F256C can support demanding clocked logic and high-speed interface functions. Its 193 I/O provide substantial board connectivity, while the 256-pin FPBGA package supports a compact 17 x 17 mm implementation when appropriate PCB density and assembly capability are available. The 1.2 V core supply improves power efficiency compared with older FPGA process generations, although system-level power also depends on I/O voltage, switching activity, configuration method, and board design. The 90 nm ECP2 architecture remains useful for cost-sensitive embedded applications where deterministic programmable logic and a broad set of I/O are more important than the highest device density available in modern FPGA families. Typical applications include industrial control and automation, communication interfaces, sensor aggregation, video or display control, embedded protocol conversion, and general-purpose digital signal processing. Designers can consolidate several fixed-function logic blocks into one programmable device, simplifying updates when interface requirements or field behavior change. Board implementation requires careful attention to the FPBGA layout, power-supply integrity, configuration signals, clocking, and I/O voltage standards. The manufacturer package documentation and pin-assignment information should govern land pattern, via requirements, assembly profile, and signal-routing decisions. Thermal performance also depends on board construction and FPGA utilization rather than package size alone. This page consolidates the exact LFE2-12E-7F256C electrical and packaging attributes, compares same-package ECP2 candidates, and organizes application and design guidance around the device's 12,000 logic cells, 193 I/O, 420 MHz performance, and 256-pin FPBGA implementation.

The Lattice Semiconductor LFE2-12E-7F484C is an ECP2 field-programmable gate array with 12K logic cells, 297 user I/O, a maximum operating frequency of 420 MHz, and a 1.2 V core supply in a 484-ball FBGA package. Its -7 speed designation places it in the performance-oriented portion of the ECP2 family, while the 484-ball package supports dense board-level connectivity. An FPGA is a programmable semiconductor whose logic, routing, and I/O behavior are defined by a configuration bitstream rather than fixed circuitry. Within the product hierarchy, an FPGA is a programmable logic device and a general-purpose semiconductor. The Lattice ECP2 family combines LUT-based logic fabric, programmable I/O, embedded memory, and DSP resources for embedded control, signal processing, communications, and industrial automation. The LFE2-12E-7F484C provides 12K LUTs and 297 I/O, giving an implementation considerable parallelism for control logic, interface bridging, data acquisition, and embedded signal processing. Its 1.2 V core operation supports power-conscious designs, while the -7 speed grade supports designs requiring higher clock performance than slower ECP2 options. The 484-ball surface-mount package also provides enough ball density for high I/O counts and multi-voltage power connections. The ECP2 architecture is built on a 90 nm FPGA process and uses configuration-based programmable logic. Its embedded DSP capability allows multiply-accumulate functions to be implemented without relying exclusively on external processors. Designers can use the programmable I/O and logic resources to consolidate parallel interfaces, protocol handling, control functions, and data-preparation logic in one device. Typical uses include industrial automation, embedded communications, video and image processing, instrumentation, consumer electronics, and compact control systems. The 297 available I/O are especially useful for board designs combining multiple buses, display or sensor interfaces, and general-purpose digital control. The -7 performance grade can also suit timing-sensitive datapaths where conservative external synchronization would otherwise increase system complexity. PCB design requires careful BGA escape routing, plane assignment, and separation of sensitive inputs from high-speed or switching nodes. Use the manufacturer pinout and package information to assign every power, ground, configuration, clock, and user I/O ball before finalizing the board. Configuration storage, clocking, decoupling, and programming-interface implementation should follow the ECP2 reference design practices. This product page consolidates the verified FPGA specifications, package details, drop-in family comparisons, and practical design considerations needed to evaluate the LFE2-12E-7F484C for a new programmable-logic design.

LFE2-12E-7Q208C

LFE2-12E-7Q208C - 12K LUT ECP2 FPGA | Lattice Semiconductor

Lattice Semiconductor LFE2-12E-7Q208C is an ECP2 field-programmable gate array with 12,000 logic cells, 131 I/O, a -7 speed grade, and a 1.2 V core voltage in a 208-pin BFQFP package. It combines programmable digital logic, embedded FPGA resources, and a surface-mount gull-wing package in a device suited to compact control, interface, signal-processing, and embedded-control systems. An FPGA is a programmable digital semiconductor whose lookup-table-based logic, registers, and routing resources are configured after manufacture. The ECP2 family belongs to Lattice Semiconductor's FPGA and CPLD product hierarchy, combining configurable logic density with a fixed package and pin arrangement. Unlike a mask-programmed logic device, an FPGA can be reprogrammed during development or, where system requirements allow, in the field to update logic, interfaces, and control sequences. The LFE2-12E-7Q208C provides 12K LUTs and 131 I/O in a 208-BFQFP package identified by distributor listings as 208-BFQFP or PQFP208. Its stated -7 speed designation supports designs requiring higher operating performance than -5 grade devices, while the 1.2 V core supply is a key constraint for power planning, termination, and signal-level compatibility. A 28 mm by 28 mm package size provides ample routing flexibility for external memory, control buses, and multi-channel interfaces. The device is positioned for applications that need more programmable logic than a small CPLD without moving to a larger FPGA package. Its 12K-cell resource level is useful for control-plane logic, bridge functions, protocol controllers, and parallel datapaths. The listed 420 MHz frequency and 131 I/O count are important search and selection criteria, although the achievable clock rate and I/O performance in a finished design remain dependent on the selected device variant, system topology, speed grade, pin constraints, and manufacturer timing documentation. Typical application areas include industrial automation, embedded control, instrumentation, communications infrastructure, consumer peripherals, and general-purpose digital signal processing. The large I/O count can support parallel data acquisition, multiple serial interfaces, memory buses, and external control signals. A design should use the manufacturer pinout and package information to assign bank voltages, ground pins, configuration pins, clock inputs, and I/O standards before finalizing the PCB layout. The principal design consideration is package and bank compatibility. A 208-pin footprint must match the 208-BFQFP mechanical drawing, including lead pitch, body dimensions, exposed thermal requirements, and solderable land pattern. Configuration, clock, decoupling, and I/O planning should be completed against the Lattice ECP2 documentation before schematic release because family membership alone does not establish interchangeability. This page combines the exact orderable MPN, package and resource details, traceable source links, same-package drop-in candidates, comparison parameters, and practical selection guidance. It is intended to accelerate engineering triage while making the remaining verification steps explicit: confirm pin compatibility, timing closure, power behavior, configuration method, and lifecycle status in the manufacturer documentation before production release.

LFE2-12E-7T144C

LFE2-12E-7T144C - 12K LUT ECP2 FPGA | Lattice

The Lattice Semiconductor LFE2-12E-7T144C is an ECP2 field-programmable gate array with 12K LUTs, 93 I/O, a -7 speed grade, and a 144-LQFP package. It is a programmable-logic semiconductor intended for digital control, interface, signal-processing, and embedded system designs where configurable parallel logic is preferable to a fixed application-specific integrated circuit. The 144-LQFP package provides 144 accessible package terminals around a square gull-wing body. An FPGA is a reconfigurable digital integrated circuit in which the interconnect and logic cells are programmed after manufacture. Within the semiconductor hierarchy, an FPGA belongs to programmable logic devices, alongside CPLDs, and is commonly used as the main digital controller in industrial, communications, consumer, and embedded applications. The ECP2 family combines LUT-based programmable logic with dedicated resources that can accelerate suitable control, arithmetic, and interface operations. The LFE2-12E-7T144C combines 12K LUTs with 93 I/O in a single device. Its -7 designation identifies the device speed grade, making it the faster of the explicitly identified -6 and -7 alternatives considered on this page. The 1.2 V operating value shown in the product listing is associated with the FPGA's core power domain. These characteristics position the device for designs requiring moderate logic density, a substantial parallel interface, and predictable implementation timing. ECP2 devices are configured from a bitstream generated by the appropriate Lattice design flow. A design must account for package-specific I/O behavior, configuration requirements, clocking, memory resources, power sequencing, and the available logic and DSP resources. Because an FPGA combines fixed silicon resources with programmable routing, successful implementation depends on constraints and device utilization rather than only the nominal LUT and I/O counts. Typical uses include industrial control and automation, communication interfaces, embedded video or image pipelines, general-purpose digital signal processing, data acquisition, and consumer or automotive-adjacent logic modules. The 93 available I/O are especially useful for parallel buses, control signals, and data interfaces, while the 12K LUT capacity supports moderate state machines, control logic, protocol handling, and multiple independent digital blocks. PCB design should preserve the manufacturer's recommended power, ground, decoupling, and configuration arrangements. Place bypassing capacitance at the appropriate supply pins, route sensitive clock and configuration signals carefully, and verify all 144 package terminals against the LQFP land pattern before fabrication. Designers migrating an existing ECP2 board should also compare speed grade, temperature option, supported I/O standards, and configuration details rather than relying on the package name alone. This page combines the verified ECP2 resource and package identifiers with drop-in-family analysis, practical FPGA integration guidance, and a parameter-by-parameter comparison. It emphasizes the distinction between a mechanically compatible replacement and a fully qualified design migration, helping engineers narrow alternatives before validating timing, I/O behavior, configuration, and system-level constraints.

LFE2-20E-5F256C - 21K LUT ECP2 FPGA | Lattice Semiconductor

The Lattice Semiconductor LFE2-20E-5F256C is an ECP2 field-programmable gate array with 21,000 logic cells, 21K LUTs, 193 user I/O, and a 1.2 V supply in a 256-ball fbBGA package measuring 17 mm × 17 mm. It is a commercial-temperature FPGA built with 90 nm CMOS technology and uses the -5 speed designation. An FPGA is a reconfigurable digital-logic semiconductor that belongs to the programmable-logic hierarchy: FPGA → field-programmable logic device → digital semiconductor. Unlike a fixed-function application-specific integrated circuit, an FPGA lets engineers configure parallel logic, state machines, interfaces, and signal-processing functions after manufacture. The ECP2 family therefore supports design adaptation without changing the physical IC, provided the required resources, interfaces, timing, and pin assignment are supported by the selected device. The verified source data identifies 21,000 ECP2 logic cells, 21K LUTs, 193 I/O, and approximately 0.28 Mbit of on-chip RAM. The 256-ball fbBGA package supports compact, high-density PCB layouts, while the 90 nm CMOS process identifies the technology generation used for the device. A 1.2 V core supply is suitable for low-voltage embedded systems, and the -5 ordering code identifies the device’s specified speed grade. The ECP2 architecture is appropriate when a design needs programmable logic resources rather than a fixed controller. Its 193 I/O provide substantial board-level connectivity for clocks, data buses, serial links, control signals, and external memory interfaces. The approximately 0.28 Mbit RAM adds on-chip storage for buffering, state retention, lookup structures, and small packet or frame-processing functions, reducing the need for external memory in suitable designs. Typical uses include embedded control, industrial automation, communications interface bridging, data acquisition, general-purpose digital signal processing, and prototype systems that require reconfigurable hardware. The commercial grade and compact BGA package make the LFE2-20E-5F256C especially relevant to cost-sensitive embedded products that need more I/O and logic than a small microcontroller can provide. Designers should verify the exact pinout, supported I/O standards, bank voltage constraints, clock requirements, and configuration method against the manufacturer documentation before layout release. Because this package contains 256 balls, PCB escape routing, via-in-pad considerations, soldering process, and assembly inspection require careful planning. This page consolidates the verified distributor specifications, package information, a drop-in cross-reference assessment, and practical selection guidance. It also distinguishes documented parameters from details that still require confirmation in the manufacturer pinout and device documentation.

LFE2-20E-5F256I

LFE2-20E-5F256I - 21K LUT ECP2 FPGA, 193 I/O, 256-FPBGA | Lattice

The Lattice Semiconductor LFE2-20E-5F256I is an ECP2 series field programmable gate array providing 21,000 logic elements (21K LUTs), 193 user I/O and 282,624 bits (276 Kb) of embedded block RAM, packaged in a lead-free 256-FPBGA (17 x 17 mm) surface-mount package with a 1.2 V core supply. The part is specified at the -5 speed grade, corresponding to a 311 MHz maximum frequency for this device family. An FPGA (field programmable gate array) is a reconfigurable digital integrated circuit whose logic, interconnect and I/O are defined by a bitstream loaded from a configuration memory rather than by a fixed mask. In the product hierarchy an FPGA sits above programmable logic, sits alongside CPLD devices, and belongs to the broader class of programmable logic semiconductors used to shorten development cycles in control, interface and signal-processing designs. Key features of this device include 2,625 configurable logic blocks (LABs), a 193-pin user I/O complement for high external connectivity, and 276 Kb of EBR block RAM for on-chip buffering, dual-port FIFO storage and video line buffers. The -5 speed grade and industrial temperature rating of -40 °C to +100 °C junction temperature suit continuous industrial duty, while the 1.2 V core supply keeps power dissipation manageable in densely packed systems. Architecturally, the ECP2 family uses a LUT4-based logic fabric with a programmable interconnect switch matrix, distributed registers, block RAM and dedicated DSP multipliers, allowing medium-complexity designs such as bus bridges, protocol controllers and multi-channel acquisition front ends to be implemented in a single device. A single 1.2 V core rail simplifies power sequencing compared with split-rail devices. Typical applications include industrial factory automation controllers, industrial Ethernet and fieldbus protocol bridges, camera and image sensor interface pipelines, LED and video timing generators, and data acquisition front ends that need deterministic parallel I/O with on-chip buffering. A key design consideration is I/O assignment: with 193 user I/O in a 256-ball FBGA, pin mapping is constrained by the package, so plan bank assignments and voltage standards against the package drawing before committing the board layout. Decoupling and configuration-memory readiness should also be verified against the manufacturer power-up sequencing guidance.

The supplied distributor information identifies the device as an ECP2 FPGA with 21K LUTs, 331 I/O, DSP support, 1.2 V operation, and a -5 speed designation. The package is identified as 484-BBGA. Detailed timing, memory, configuration, electrical, and temperature data are not present in the supplied source excerpts, so those values are not asserted here. The design should be checked against the manufacturer datasheet before layout, power budgeting, or production qualification. A -5 FPGA speed designation indicates the manufacturer’s speed-grade family, but the operating-temperature grade and timing margins are not stated in the verified excerpts. The 1.2 V core supply is the confirmed supply value, while external I/O supply requirements, configuration voltage, and power consumption require the full manufacturer documentation. The 484-BBGA package requires a PCB footprint and thermal design appropriate for a large fine-pitch BGA. Typical design uses include industrial automation, communications equipment, video and image processing, embedded control, and general-purpose programmable logic. The large I/O count can support external memory, parallel buses, sensor interfaces, transceiver connections, and control peripherals. DSP capability can reduce external processing hardware when the design uses fixed-point or parallel signal-processing functions implemented within the FPGA. For a new PCB, preserve the exact Lattice package pinout and ball assignment, define clean power and ground planes, and validate high-speed routing with the complete timing and pinout documentation. Do not treat distributor snippets as a substitute for the manufacturer datasheet. This page consolidates the verified distributor identity, package, density, I/O, voltage, and sourcing information while explicitly separating unknown technical details. The practical advantage of this part is its combination of moderate FPGA logic density, extensive I/O, DSP support, and a 1.2 V core architecture. It is more suitable than a small logic device when a design needs substantial parallel connectivity, while the -5 grade should be selected only after confirming timing requirements against the complete Lattice documentation.

A field-programmable gate array is a programmable digital integrated circuit composed of configurable logic blocks, programmable interconnect, and input/output resources. Within the semiconductor hierarchy, an FPGA is a digital IC, and within programmable logic, the LatticeECP2 family provides a mid-density platform combining logic fabric, block RAM, multipliers, DSP capability, and high-speed I/O. This device occupies the 21K-cell position in the ECP2 family. The verified device characteristics include a 90 nm CMOS process, 1.2 V supply, 21K logic cells, 331 I/O, and a -5 speed designation. Its 484-ball surface-mount FBGA package supports high pin density and is supplied in a manufacturer-standard tray. Mouser classifies the part as an FPGA with 21K LUTs, 331 I/O, and DSP capability. The LFE2-20E-5F484I is positioned for designs where deterministic programmable logic, embedded DSP processing, and a large parallel I/O count are more important than the lowest unit price. Its 484-pin FBGA footprint can support substantial external connectivity, although BGA layout demands careful escape routing, continuous supply planes, and controlled via distribution. Because the complete verified data does not provide pin-level tables, a package drawing should be consulted before layout is released. Typical uses include industrial control and automation, networked data acquisition, video or image-processing front ends, communications infrastructure, and test equipment. The 331 I/O count makes the device appropriate for systems that terminate many parallel buses or high-pin-count expansion interfaces, while the ECP2 DSP resources can accelerate filtering, arithmetic, and signal-processing functions without relying on a separate processor. The primary design consideration is package complexity. A 484-pin FBGA assembly needs thermal-via arrays, short power-plane connections, multiple decoupling positions, and escape routing for configuration, clock, and high-speed interfaces. Signal integrity should be validated against the actual interface rate because the verified web results do not specify a complete I/O performance table. This page combines verified distributor identification, device-family positioning, same-package ECP2 alternatives, and practical BGA design guidance. It also separates confirmed specifications from data that must be checked in the LatticeECP2/M family datasheet before schematic release, PCB layout, or production sourcing.

The -5 ordering option identifies the device’s speed grade, making this FPGA suitable for high-density programmable logic, interface bridging, embedded control, signal processing, and industrial data-acquisition systems that require substantial parallel I/O in a single package. An FPGA is a programmable semiconductor whose internal lookup tables, registers, memory blocks, and programmable I/O can be configured after manufacture. Within the product hierarchy, this device belongs to the ECP2 FPGA family, a low-power programmable-logic platform that can implement control logic, parallel data paths, communications interfaces, and DSP-assisted functions. The LFE2-20E-5F672C combines approximately 21K LUTs with 402 I/Os, providing high connectivity for modules and systems with many external buses, sensors, converters, and display links. The most prominent specifications are 21K LUTs, 402 I/Os, and a 1.2 V operating supply. These headline figures distinguish it from smaller ECP2 devices that offer fewer logic cells and I/O resources. The -5 suffix identifies the performance grade, while 672C denotes the large ball-grid-array package used for this ordering option. The package provides substantial interconnect capacity but requires careful ball assignment, escape routing, and multilayer-PCB planning. ECP2 devices support programmable logic architecture in which multiple parallel data channels can be routed through LUTs, flip-flops, block RAM, multipliers, and DSP resources. The large I/O count is particularly valuable for designs that must adapt to several external bus widths or aggregate many sensor inputs. Because FPGA timing depends on the selected clocking, I/O standards, routing, and design implementation, system performance should be evaluated with the Lattice Semiconductor development tools and timing constraints used for the production design. Typical applications include industrial control and automation, test and measurement, communications equipment, video and image processing, embedded instrumentation, and high-speed interface consolidation. The device is also appropriate for prototype platforms and production systems that need configurable logic, substantial I/O, and deterministic parallel processing without the development cycle of a custom ASIC. A lower-pin-count ECP2 device may be preferable when only a small number of external connections is required. PCB implementation should reserve the FPGA power rails as a dedicated power-management structure, follow the manufacturer’s ball-assignment and decoupling guidance, and route high-speed interfaces with controlled impedance. Designers should also verify the selected I/O standard against the board connector and external clock source before committing the pinout. This product page combines the exact ECP2 ordering information with practical guidance for pin planning, performance grading, interface selection, and family alternatives. It helps engineers determine whether the 21K-LUT device, 402-I/O density, -5 grade, and 672-BBGA footprint match the mechanical and functional requirements of a new programmable-logic design.

The exact I/O voltage range, supported I/O standards, embedded-memory configuration, and clocking limits must be confirmed in the Lattice Semiconductor ECP2 documentation before a board is released. Typical applications include industrial automation modules, sensor and instrumentation interfaces, communication bridges, embedded control systems, and video or image-processing front ends. In each case, parallel programmable logic can implement protocol handling, state machines, timing, filtering, and control functions, while the dedicated DSP block supports selected multiply-accumulate operations. Product qualification should match the required logic density, I/O count, speed target, power budget, and operating environment. For PCB design, treat the 208-pin PQFP footprint, exposed thermal requirements, power rails, configuration interface, and decoupling network as a complete package. Confirm every signal's I/O standard and voltage-domain compatibility against the Lattice Semiconductor pinout and device documentation. Configuration storage, clock topology, and programming support should be verified before committing a system design. This page combines verified product attributes, same-family drop-in migration options, application guidance, and practical design cautions. It helps engineers compare speed grades and package-compatible ECP2 options without overlooking differences in operating grade, qualification, or configuration requirements.

Lattice Semiconductor LFE2-20E-5Q208I is an ECP2 field-programmable gate array (FPGA) with 21,000 logic elements, 131 user I/Os, and 282,624 RAM bits in a 208-pin BFQFP package. It operates from a 1.2 V core supply and is configured as an industrial-temperature grade device with speed grade -5. An FPGA is a programmable semiconductor in the broader logic semiconductor and digital processing hierarchy. Its configurable lookup logic, embedded block RAM, and programmable I/O blocks allow one physical device to implement control logic, interface bridging, signal processing, and embedded system functions. The ECP2 family combines this reconfigurable architecture with a 1.2 V core and deterministic embedded memory resources for compact industrial and communications designs. The LFE2-20E-5Q208I provides 21,000 logic elements organized into 2,625 logic array blocks, 282,624 RAM bits, 131 user I/Os, and one DSP multiplier according to the manufacturer listing. Its 208-pin gull-wing package exposes substantially more interface pins than smaller FPGA packages, making it suitable for parallel buses, memory interfaces, high-speed control signals, and multi-channel data acquisition systems. Device selection depends on the -5 speed grade, industrial-temperature ordering suffix, 1.2 V core architecture, and available package resources. Because the FPGA receives its function from a configuration bitstream, engineers should also verify the required configuration memory, programming interface, clocking scheme, I/O standards, and system-level timing before releasing a PCB for production. Typical uses include industrial automation controllers, test-and-measurement instruments, communications interface modules, embedded video and imaging control, sensor aggregation, and general-purpose digital signal processing. The large I/O count is especially useful when a design must connect multiple external memory devices, converters, communication transceivers, and precision interface components without requiring a separate large package. A key design consideration is that the 208-pin package requires careful escape routing and a stable 1.2 V core rail. Follow the manufacturer pinout and recommended power-supply connections, place decoupling capacitors close to the supply pins, and preserve signal-integrity margin on high-speed outputs. Configuration, clock, and I/O standards should be validated against the exact ECP2 device documentation used for the design. This page organizes the verified device identity, package information, resource counts, comparison points, and practical selection guidance into one engineering-focused reference. It also distinguishes verified ECP2 alternatives from generic FPGA substitutes so engineers can focus on genuine package and parameter compatibility.

It operates from a 1.14 V to 1.26 V supply and is ordered in the -6 speed grade. The device is designed for low- to mid-density applications that need programmable logic, flexible I/O, embedded memory, and DSP capability without the complexity of a high-end FPGA. An FPGA is a reprogrammable semiconductor whose configuration defines digital interconnect and processing functions after manufacturing. The ECP2 family belongs to the broader programmable-logic hierarchy, combining configurable logic blocks, block RAM, programmable I/O, and dedicated DSP resources. This makes the LFE2-20E-6F256C suitable for control logic, interface bridging, data acquisition, signal conditioning, and embedded protocol handling where a fixed application-specific integrated circuit would be less flexible. Key features include 2,625 look-up tables, 21,000 logic elements, 282,624 total RAM bits, and 193 user I/O. The device includes DSP capability and supports a 1.2 V operating supply, with a documented operating range of 1.14 V to 1.26 V. Its 256-terminal square BGA package uses ball-grid-array interconnect rather than perimeter leads, supporting dense I/O density on compact boards. The -6 ordering code identifies the performance grade used in the manufacturer ECP2 ordering scheme. The ECP2 architecture is intended for designs that benefit from in-system reconfiguration and deterministic parallel logic implementation. Its 193 user I/O can connect external memory, transceivers, converters, and display or industrial interface circuitry. Embedded RAM supports buffering, packet storage, and general-purpose state-holding functions, while DSP resources accelerate multiply-accumulate operations found in filtering and signal-processing paths. Configuration must be completed before normal user logic begins operating. Typical uses include industrial control panels, embedded communication gateways, video timing and control, industrial sensor acquisition, consumer peripherals, and communications infrastructure. The dense BGA footprint is appropriate for multilayer PCBs where escape routing, via-in-pad practices, and careful ball-to-ball inspection matter. It is less convenient than a leaded package for prototype work, but it supports higher I/O density in a compact land pattern. Design with the ECP2 pin-connection and pinout documentation for the F256 package before assigning PCB tracks. Confirm the configuration interface, clock requirements, supported I/O standards, and bank power sequencing against the manufacturer datasheet.

Lattice Semiconductor LFE2-20E-6F256I is an ECP2 field-programmable gate array with 21,000 logic cells, 193 user I/O, a 1.2 V core supply, and a -6 speed grade in a 256-ball BGA package. The industrial-temperature device combines programmable logic, embedded block RAM, and DSP resources in a single reconfigurable semiconductor, allowing designers to implement parallel control, signal processing, interface bridging, and protocol handling without relying on fixed-function logic. An FPGA is a programmable semiconductor whose digital circuits are defined through a configuration bitstream rather than a fixed mask set. Within the device hierarchy, the LFE2-20E family is an FPGA and CPLD-class programmable logic device, while ECP2 identifies Lattice Semiconductor's low-cost, low-power ECP2 platform. Its combination of 21K LUTs, 193 I/O, 276 Kb of block RAM, and 90 nm process technology makes it useful when design flexibility, parallel processing, or deterministic hardware control is more valuable than a very high clock rate. The verified distributor information identifies 21K LUTs, 193 user I/O, one DSP block, a 1.2 V core voltage, and a -6 performance designation. It also identifies a 256-pin BGA package and industrial-temperature grading. These characteristics position the device for embedded control, industrial automation, communications infrastructure, test equipment, and embedded video systems where multiple parallel channels must operate under one programmable controller. The ECP2 architecture supports a compact implementation of control logic, data acquisition paths, protocol converters, and DSP-style pipelines. Because the device is configured rather than permanently wired, a single hardware platform can be revised during development without changing the PCB. Designers must still account for configuration setup time, I/O-bank voltage constraints, clocking requirements, and the high pin count and BGA routing demands of the 256-ball package. Typical uses include industrial controllers and factory automation, networking and communications equipment, embedded processing systems, instrumentation, and secure or specialized control logic. The 193 I/O count is particularly useful for parallel buses, status and control signals, and high-pin-count programmable peripherals. The 21K LUT capacity also allows logic consolidation when discrete programmable devices would otherwise increase board area and complicate inventory management. The primary PCB consideration is that a 256-ball BGA requires careful escape routing, a suitable multilayer land pattern, assembly process controls, and power and ground distribution suitable for a 1.2 V core. Engineers should validate the exact ball map, supported I/O standards, configuration method, clocking scheme, and decoupling requirements against the manufacturer documentation before committing the PCB layout. This product record combines verified distributor specifications with practical selection, comparison, application, and design guidance. It also distinguishes an explicitly identified ECP2-family option from unsupported substitute claims, helping engineers identify what is verified and what still requires schematic, pinout, timing, and lifecycle review before a production decision.

The device is associated with a -6 speed grade and is manufactured using 90 nm CMOS technology in a 23 x 23 mm package. An FPGA is a semiconductor whose digital logic and connectivity can be configured after manufacture. The ECP2 family belongs to the FPGA and CPLD hierarchy within integrated circuits and provides programmable hardware for implementing parallel processing, control logic, interfaces, and fixed-function replacements without changing the PCB. Unlike a fixed ASIC, an FPGA permits design revisions through programmable configuration rather than a full silicon respin. The principal features visible in the verified product data are the 21K LUT count, 331 available I/O, 357 MHz stated operating frequency, 1.2 V core voltage, and -6 speed designation. The LFE2-20E-6F484C designation also identifies a 484-ball package and an approximately 21,000-cell ECP2 device. Its high ball and I/O counts make it appropriate for designs requiring extensive parallel connectivity, multi-bank memory interfaces, or multiple peripheral functions. The device is implemented in 90 nm CMOS and operates from a stated 1.2 V core supply. This architecture places the FPGA within the broader semiconductor and programmable-logic hierarchy while supporting integration of substantial logic resources into one component. Designers must still account for configuration storage, clocking, voltage regulation, signal integrity, and power budgeting when laying out a board around the 23 x 23 mm FBGA. Typical application categories include industrial automation, industrial networking, data acquisition, communications infrastructure, embedded control, and test equipment. The combination of 21K LUTs and 331 I/O can suit parallel sensor aggregation, protocol bridging, motion or machine control, and auxiliary processing beside a higher-level processor. Exact implementation limits depend on timing closure, memory resources, I/O standards, configuration method, and power budget. When designing a PCB for this FPGA, use the manufacturer package drawing and pinout for ball assignment and escape routing. The 484-ball land pattern generally requires multilayer PCB construction with careful power-plane distribution, via-in-pad or microvia strategies where appropriate, and controlled-impedance routing for high-speed interfaces. Decoupling should follow the manufacturer power-supply recommendations rather than relying on generic capacitor values. This product record combines verified distributor specifications, family-level replacement information, and practical implementation considerations that are not presented together on a standard distributor listing. It also distinguishes exact source-supported values from parameters that require confirmation from the manufacturer datasheet before schematic release or PCB layout.

The ECP2 family combines these resources on a 90 nm process and supports configurable logic, memory, and DSP-based arithmetic within a single device. Key features include 21,000 logic cells, 2,625 logic blocks, 331 I/O, 331 DSP blocks, 282,624 EBR bits, and a 1.2 V operating supply. The -6 suffix identifies the target device speed grade, while the final I indicates the industrial temperature option. Its 484-FBGA package provides a dense interface arrangement for multilayer PCB designs, although exact ball assignments must be checked against the manufacturer package drawing before layout. The ECP2 architecture is appropriate for control logic, data acquisition, industrial automation, communications, embedded signal processing, and equipment control. Its 21K-cell fabric can host parallel state machines, protocol engines, and DSP pipelines, while 331 I/O provide external interfaces and the verified listing identifies one DSP block rather than a larger DSP inventory. The quoted 331 DSP value is retained exactly because the supplied distributor snippet does not distinguish a physical multiplier count from a logical DSP count. A primary design consideration is that a 484-ball FBGA is not a low-pin-count PCB package. Designers must plan power and ground distribution, controlled-impedance routing, via-in-pad or via-adjacent escape structures where required, and careful ball-grid alignment. The industrial-temperature ordering code must also be checked against the exact system requirements because commercial and industrial variants may use different temperature grades. This page consolidates the verified distributor specifications, package and source links, practical FPGA design guidance, and same-package replacement candidates into one engineering reference. It also distinguishes published values from unavailable information so engineers can verify timing, memory organization, pin assignments, pricing, and lifecycle commitments before committing a new PCB revision.

The -6 speed grade supports operation up to 357 MHz system clocking, and the device is built on a 90 nm CMOS process. An FPGA is a programmable logic device: instead of a fixed circuit, the chip contains a matrix of look-up tables (LUTs), programmable interconnect and dedicated hard blocks that engineers configure at runtime to implement any digital function from a single register-transfer level (RTL) design. FPGAs sit in the hierarchy of programmable logic devices, above simple programmable logic arrays (PLAs) and complex PLAs (CPLDs), and are widely used where a design must change without a silicon respin. The ECP2 family targets cost-sensitive, mid-complexity designs needing logic, moderate DSP capability and generous I/O. Key characteristics of this device include 21,000 logic cells for general combinational and sequential logic, 402 user I/O for external bus and peripheral connectivity, integrated DSP multiplier blocks for arithmetic-heavy pipelines, and single 1.2 V core operation with separate I/O supply domains. The 672-ball package gives one of the highest I/O counts in the ECP2 range, which allows dense parallel buses, multiple high-speed memory interfaces and video or network data paths to be realized without an external glue layer of discrete logic. Technically, the ECP2 architecture uses a LUT-based logic fabric with a programmable switch matrix, dedicated block RAM for on-chip storage, and DSP blocks for multiply-accumulate operations. The fabric is configured from SRAM and the device is re-programmable in-circuit, so field upgrades are possible. Because the die is built on 90 nm CMOS, the core voltage of 1.2 V balances leakage and switching performance against static power draw in industrial control, communications and embedded industrial-control products. Typical applications include industrial control and factory automation panels, networked sensor and gateway equipment, video and image capture pipelines, interface consolidation for serial links, and general embedded control logic that benefits from a high pin count. The 357 MHz speed grade makes it appropriate for designs combining parallel bus logic with a moderate-speed control processor. When laying out a board, treat the FBGA as a fine-pitch ball-grid array with several power and ground balls distributed through the array rather than only at the perimeter. Follow the manufacturer's recommended decoupling and ball-assignment guidance exactly, and confirm the specific I/O standard and voltage banking for every external interface before routing. This page consolidates manufacturer device data, package and pin-count details, drop-in alternatives from the same ECP2 family, and practical design notes that are not gathered together in the factory datasheet itself, helping engineers qualify or replace the device quickly.

The 331-I/O count is especially useful for designs that must connect multiple buses, capture parallel data, or control a substantial number of external signals. The DSP resources allow selected arithmetic and filtering pipelines to be implemented in parallel rather than relying entirely on sequential processor execution. Board-level implementation should follow Lattice's published high-density BGA layout, power, and decoupling guidance. Differential pairs, clock inputs, and high-speed memory interfaces require controlled impedance, continuous return paths, and length matching; the 1.2 V core rail also requires careful sequencing and filtering. Because this MPN is reported as obsolete by one indexed source while distributor listings remain available, procurement planning should confirm lifecycle status, date codes, traceability, and current inventory before a new production release. This page consolidates distributor specifications, package identification, lifecycle signals, and same-family upgrade paths with practical implementation guidance. It also distinguishes confirmed parameters from details that require verification against the manufacturer documentation, helping engineers evaluate fit without treating distributor snippets as a substitute for the complete datasheet.

LFE2-20E-7F672C - 21K LUT FPGA | Lattice Semiconductor

Lattice Semiconductor LFE2-20E-7F672C is a 21,000-logic-cell field-programmable gate array (FPGA) with a maximum frequency of 420 MHz, a 1.2 V operating supply, 402 I/O, 318 Kb of embedded memory, and a 672-ball FBGA package. The device belongs to the LatticeECP2 family and combines programmable logic, DSP resources, and system-level connectivity in a single surface-mount semiconductor package. A field-programmable gate array is a semiconductor whose logic architecture is configured after fabrication. In the device hierarchy, an FPGA is a programmable logic device, while the LatticeECP2 family is positioned as a low-power FPGA family for embedded control, communications, industrial, and consumer applications. Unlike a fixed-function application-specific integrated circuit, the LFE2-20E-7F672C permits design revisions, field updates, and adaptation to multiple control protocols without changing the PCB layout. Key features include 21,000 logic elements or LUTs, 318 Kb of embedded memory, and 402 user I/O. The supplied specifications identify a maximum operating frequency of 420 MHz and a 1.2 V operating supply voltage. Its 672-ball BGA package provides dense routing access for designs requiring numerous external connections. The -7 ordering code denotes the device’s selected speed and temperature ordering option, while exact pin functions, memory organization, DSP count, and I/O standards require confirmation in the manufacturer documentation. The device is manufactured using 90 nm technology according to the verified technical listing. This places it in the ECP2 product class, where configurable logic can implement control, data acquisition, protocol bridging, and embedded signal processing. The 1.2 V supply supports contemporary low-voltage digital systems, but board design must account for separate core and I/O supply requirements where the family documentation specifies them. Configuration, programming, clocking, decoupling, and power sequencing must follow the applicable LatticeECP2 guidance. Typical uses include industrial automation, embedded communications, video or image processing, sensor acquisition, consumer electronics, and compact embedded control systems. The 21K LUT capacity is appropriate for parallel control logic and moderate DSP workloads, while 402 I/O is useful when the design connects multiple buses, displays, converters, or external processors. Exact suitability depends on available routing, clock resources, hard peripherals, memory requirements, and the selected package. When planning the PCB, verify the official 672-ball footprint, ball assignments, exposed-pad requirements, and power planes before layout release. Provide local decoupling according to the family datasheet, design clean clock and configuration paths, and verify signal-integrity behavior for every high-speed interface. Because the supplied web results summarize rather than reproduce the full pinout, the complete package pin list is intentionally not asserted here. This product page consolidates verified distributor specifications, same-family replacement candidates, package details, pricing status, and practical selection guidance. It is intended to accelerate engineering comparison while clearly separating confirmed parameters from information that must be checked in the LatticeECP2 datasheet and package documentation.

LFE2-20E-7Q208C

LFE2-20E-7Q208C - 21K LUT ECP2 FPGA | Lattice

The Lattice Semiconductor LFE2-20E-7Q208C is an ECP2 field-programmable gate array with 21K LUTs, 131 I/O, 1.2 V core voltage, and a -7 speed grade in a 208-pin BFQFP package. It is designed for embedded systems that require programmable logic, parallel interfaces, control functions, and moderate signal-processing capability in a single reconfigurable device. An FPGA is a digital semiconductor whose internal logic, interconnect, and peripheral behavior are configured after manufacture. It belongs to the programmable-logic hierarchy: FPGA > field-programmable gate array > digital integrated circuit > semiconductor. Unlike a fixed-function microcontroller or application-specific controller, an FPGA can implement parallel datapaths and hardware state machines while retaining the flexibility to update logic through a configuration interface. The LFE2-20E-7Q208C provides 21K LUTs, 131 user I/O, and a 1.2 V supply while operating in the -7 speed grade. The 208-pin BFQFP package provides 131 I/O rather than using all 208 package positions for user signals, leaving positions for power, ground, configuration, and other dedicated functions. Its programmable architecture supports designs that require deterministic control, interface adaptation, protocol handling, or parallel data acquisition. The ECP2 architecture is appropriate for designs combining control logic with modest data processing. The 1.2 V core voltage supports integration into systems that partition supply rails by function, while the -7 grade identifies the device’s speed classification. Exact logic-cell counts, embedded-memory capacity, supported I/O standards, configuration modes, and electrical limits should be confirmed in the manufacturer datasheet before finalizing a high-speed or safety-critical design. Typical uses include industrial control, communications infrastructure, test and measurement equipment, embedded data acquisition, display interfaces, and compact control systems. In each case, the FPGA can execute multiple state machines concurrently, absorb protocol-specific formatting, and isolate time-critical operations from a companion processor. The 131 available I/O are particularly useful for parallel buses, capture logic, and mixed peripheral interfaces. A key design consideration is the distinction between package capacity and usable user I/O. A 208-pin package does not provide 208 general-purpose pins; this device has 131 user I/O. Board planning must also account for the 1.2 V core supply, configuration pins, decoupling, programming access, and the pin assignments required by the selected device family and package variant. This page combines the verified device identity, electrical highlights, package information, sourcing workflow, and drop-in replacement analysis with practical guidance for FPGA selection. It is intended to help engineers distinguish a genuine same-footprint replacement from a merely similar FPGA and to plan a migration without overlooking configuration, pinout, and supply requirements.
