LFE2-35E-5F484C

LFE2-35E-5F484C - 32K LUT ECP2 FPGA | Lattice Semiconductor

Lattice Semiconductor LFE2-35E-5F484C is an ECP2 field-programmable gate array with 32,000 look-up tables, 331 I/O sites, a 1.2 V core supply, and a 484-ball FBGA package. It combines programmable logic, embedded memory, and advanced DSP blocks in a single surface-mount device suited to consolidated control, signal-processing, and interface designs. An FPGA is a reconfigurable digital semiconductor that combines programmable logic blocks with programmable interconnect resources. At the system level, it belongs to the programmable-logic hierarchy: FPGA, programmable-logic device, digital integrated circuit, and semiconductor. Unlike a fixed-function microcontroller or application processor, an FPGA implements parallel hardware logic that can be rewritten for different protocols, data paths, or control functions after manufacture. The ECP2 family provides 32,000 LUTs, 331 I/O, and advanced DSP blocks in the specified device. The 1.2 V core operating voltage supports modern low-voltage digital designs, while the 484-FBGA package offers a dense route for implementing many board-level interfaces in a compact component. The -5 ordering suffix identifies the selected Lattice speed and temperature grade, and the trailing C identifies the commercial package configuration. At an architectural level, the FPGA fabric can implement parallel datapaths, control logic, protocol bridges, and fixed-point or filtered DSP functions. The embedded DSP blocks accelerate suitable arithmetic workloads while programmable interconnect routes signals between LUTs, registers, memories, block RAM, DSP elements, and I/O. Designers must still map clocks, resets, buses, and interfaces in the development tool and verify timing after each implementation. Typical uses include industrial control, data acquisition, communications infrastructure, embedded vision, instrumentation, and general-purpose digital signal processing. Its combination of 331 I/O and programmable logic is especially useful when a design needs many parallel external connections, custom serial protocols, or multiple independent processing pipelines rather than a single sequential processor core. Board design should follow the manufacturer pinout and recommended decoupling guidance for the 484-FBGA package. Confirm that every power, ground, configuration, clock, and high-speed signal connection matches the selected device variant, and route configuration pins so the FPGA enters a valid operating state during power-up, reset, and reprogramming events. This product overview combines the device's verified architecture and ordering information with family-level comparison data and practical implementation guidance. It helps engineers evaluate the LFE2-35E-5F484C for high-density programmable-logic, DSP, control, and I/O-intensive designs before completing device-specific schematic and timing review.

LFE2-35E-5F484I

LFE2-35E-5F484I - 32K LUT, 331 I/O ECP2 FPGA | Lattice

The Lattice Semiconductor LFE2-35E-5F484I is an ECP2 field-programmable gate array with approximately 32,000 logic cells, 331 I/O, and a -5 speed grade in a 484-ball BGA package. Its 1.2 V core voltage places it in the LatticeECP2 family of low-power programmable logic devices. The part is designed for industrial-temperature applications requiring moderate logic density, substantial user I/O, and programmable digital signal processing support. An FPGA is a reconfigurable semiconductor whose lookup tables, registers, interconnect, and programmable I/O implement digital logic functions after configuration. Within the product hierarchy, the LFE2-35E-5F484I is an FPGA, a programmable-logic IC, and a semiconductor. Compared with fixed-function logic, an FPGA supports field updates, parallel processing, hardware customization, and design changes without changing the PCB. The ECP2 family balances programmable logic, embedded DSP capability, and low-power operation in a single device. The device provides approximately 32K LUTs and 331 I/O, giving it the resources to consolidate multiple digital subsystems onto one package. Its -5 speed designation identifies the selected performance grade, while the 484-ball BGA package supports dense PCB routing and a large pin count. The 1.2 V core supply is suitable for low-energy logic systems. Exact memory-block, DSP-count, differential-I/O, operating-temperature, and package-dimension details should be confirmed in the LatticeECP2/M family data sheet before design release. The LFE2-35E-5F484I belongs to the ECP2 family rather than the ECP2M family. This distinction matters because the family data sheet identifies advanced DSP and high-speed SERDES capabilities that are not automatically shared by every ECP2 member. Board-level compatibility must therefore be based on the exact package, speed suffix, I/O arrangement, power rails, and configuration requirements rather than the device family name alone. Typical uses include industrial control, communications interfaces, test equipment, embedded signal processing, data acquisition, and general-purpose programmable logic. Its combination of 331 I/O and a large logic-cell count is useful when an interface-rich design must consolidate logic that would otherwise require multiple programmable devices. A synchronized switching converter or multiple regulators may be required because the core and I/O supplies can have distinct voltage requirements. When planning a PCB, reserve the complete 484-ball land pattern, verify every power and ground ball assignment, and confirm differential-pair routing and configuration interface requirements against the family documentation. Treat the BGA package as a fine-pitch assembly constraint requiring appropriate land geometry, solder mask definition, thermal design, and inspection coverage rather than treating the FPGA as a generic fine-pitch component. This page combines the exact LFE2-35E-5F484I ordering characteristics with same-family drop-in candidates, application guidance, and design-focused comparison data. It is intended to accelerate engineering selection while keeping unresolved device details subject to verification in the manufacturer family documentation.

The Lattice Semiconductor LFE2-35E-5F672C is an ECP2 FPGA with 32,000 logic cells, 450 I/O, and a 1.2 V supply in a 672-pin FPBGA package. The device is identified as an LatticeECP2 field-programmable gate array using 90 nm technology, with a 27 x 27 mm package and 311 MHz maximum operating frequency. It is intended for complex logic and memory applications where programmable parallel processing, high I/O density, and embedded block RAM are useful. An FPGA, or field-programmable gate array, is a programmable digital semiconductor that combines configurable logic blocks, programmable interconnect, memory resources, and I/O into one device. The LFE2-35E-5F672C belongs to the ECP2 family, a low-power FPGA platform used for embedded control, communications, signal processing, and general-purpose programmable logic. Its 450 I/O provide substantial connectivity for parallel buses, memory interfaces, and control logic. The verified product information identifies 32,000 cells, 450 I/O, a 1.2 V operating voltage, 90 nm process technology, and a -5 speed grade. The 672-pin FPBGA package is specified as a surface-mount, tray-packaged component. The ECP2 architecture is suited to designs requiring deterministic parallel logic rather than a high-level microcontroller workload, while the large pin count supports high-bandwidth external memory and peripheral connectivity. The LFE2-35E-5F672C is identified as obsolete by GlobalSpec data, so procurement should account for lifecycle risk rather than assuming new production availability. Distributor records and marketplace listings may still show inventory, but availability, pricing, and lead time require confirmation at the time of purchase. A 672-pin BGA package also requires careful PCB layout, controlled reflow, and adequate via-in-pad or fanout routing for reliable assembly. Typical applications include industrial control systems, communications infrastructure, test and measurement equipment, embedded video processing, interface aggregation, and high-density logic prototyping. The device can also be used in FPGA-based embedded systems where programmable logic, block memory, and a large I/O count must coexist on one package. Designers should verify the exact pinout, power rails, configuration method, supported I/O standards, and memory interface requirements against the manufacturer documentation before layout. Since the package exposes 672 balls, power and ground distribution, decoupling, escape routing, and thermal management are especially important. A PCB with adequate layer count, via density, and assembly-process capability should be planned before committing to this footprint. This product page consolidates the verified distributor and manufacturer-oriented specifications, lifecycle status, package information, and same-family replacement candidates into one engineering-focused reference. It also highlights the practical distinction between true package-compatible alternatives and ECP2 devices that require a different footprint.

LFE2-35E-5F672I

LFE2-35E-5F672I - 32K LUT ECP2 FPGA, 450 I/O, 672-BBGA | Lattice

The Lattice Semiconductor LFE2-35E-5F672I is an ECP2 field-programmable gate array (FPGA) providing 32,000 logic cells (32K LUTs) with 450 user I/O, built on a 0.09 um embedded process and offered in a 672-ball BGA package for a 1.2 V core supply, -5 speed grade, industrial temperature range. An FPGA is a programmable logic device: a semiconductor whose interconnect and logic fabric are configured at power-up from a bitstream held in external flash, so one physical part can implement many different circuit functions. The LFE2-35E-5F672I belongs to the ECP2 family, which sits in the broader programmable-logic hierarchy: FPGA -> programmable logic device -> digital ASIC alternative -> digital integrated circuit. Lattice positions the ECP2 series as a cost-effective, low-power mid-density platform for high-speed processing and data transmission designs that need more parallelism than a microcontroller or discrete logic can deliver. Catalogued device attributes for this part include 32,000 logic cells, 450 user I/O, dedicated DSP resources, a 1.2 V core voltage, and the -5 speed grade in an industrial temperature option. The 672-ball BGA land pattern offers a large number of high-speed differential-capable I/O in a compact square footprint, which is what makes the device attractive for parallel data acquisition, video pipeline processing and multi-channel interface bridging where a smaller package would run out of pins. The -5 speed suffix denotes the Lattice speed grade for this device within the ECP2 family, so it can be ordered alongside slower -3 and faster -7 options in the same 672-ball package without changing the board layout. The trailing I character marks the industrial temperature grade, while the 5 in the part number denotes the 5 V configuration bank family characteristic of this ECP2 variant. Device configuration is handled through the standard Lattice ECP2 configuration path, so the design can be programmed in-circuit from a serial flash or a microcontroller. Typical end uses for this part include video and image pipeline processing, industrial control and test instrumentation, communications and data-transmission equipment, and general-purpose signal conditioning or protocol bridging. In each case the combination of 32K LUTs, 450 I/O and DSP capability allows several parallel datapaths to be consolidated into one device instead of a collection of discrete components. When designing around the LFE2-35E-5F672I, treat the 1.2 V core rail as the critical supply: decouple it close to the ball grid with low-inductance ceramic capacitance and keep the switching-noise budget for surrounding analog sections in mind, since a 672-ball BGA also presents a substantial thermal and decoupling challenge on multilayer boards. Use the manufacturer datasheet for the full pin, ball and power-supply assignment list. This page consolidates the verified distributor and catalogue data for the LFE2-35E-5F672I, adds same-footprint drop-in alternatives from the ECP2 and related Lattice families, and supplies the application, thermal and layout guidance that a bare catalogue listing does not provide.

LFE2-35E-7F672C - 32K LUT ECP2 FPGA, 450 I/O, 672-BBGA | Lattice

The Lattice Semiconductor LFE2-35E-7F672C is an ECP2 field-programmable gate array (FPGA) providing 32,000 look-up tables, 339,968 gates and 450 user I/O in a 672-ball BGA (672-BBGA) package, operating from a 1.2 V core supply at the -7 speed grade. An FPGA is a programmable semiconductor whose logic fabric, memory and interconnect are configured at power-up from a non-volatile configuration memory. Where an ASIC fixes a function in silicon, an FPGA lets a designer reconfigure the same package pinout for different logic, interface or DSP tasks, shortening development cycles and supporting field upgrades. The ECP2 family sits at the low-cost, high-volume end of Lattice's portfolio and is widely used for control, interface and signal-processing logic that does not require the resources of a midrange FPGA. Key features of this device include 32,000 LUTs (reported as 32K LUTs by distributor listings), a 339,968 gate count, and 450 general-purpose I/O in a single square BGA package with ball terminals. The 1.2 V core supply keeps on-board power dissipation manageable in dense control designs, and the -7 speed grade is the fastest ordering option in the ECP2 line, which matters for timing closure on multi-cycle bus and pipeline-heavy logic. The family also supports dedicated DSP and memory resources for arithmetic and buffer-heavy data paths. Technologically the part belongs to the ECP2 low-cost architecture, where the logic fabric is built from 4-input LUTs with dedicated block RAM and DSP multipliers. Because configuration is non-volatile, the device boots directly into the loaded bitstream without an external configuration PROM, which reduces board area and BOM cost on production builds. Exact block counts for DSP multipliers and block RAM for this ordering code are listed as [DATA_NEEDED: DSP block count] and [DATA_NEEDED: block RAM count] in the specification table; consult the manufacturer datasheet for the definitive resource breakdown before finalizing a design. Typical applications for this device include industrial control and factory automation modules, video timing and interface bridging, audio and general DSP pipelines, network and data-communication interface cards, and instrumentation front ends. The high I/O count of 450 in a single 672-ball package makes it especially useful where many parallel lines, memory interfaces and differential pairs must converge on one device. When designing around this FPGA, budget for the BGA escape-routing density of a 672-ball package, match the printed board stack-up to the manufacturer's ball-pitch and land-pattern recommendations, and confirm the -7 speed grade timing margin against your slowest clock domain.

LFE2-50E-6F484C - 48K LUT ECP2 FPGA | Lattice

The Lattice Semiconductor LFE2-50E-6F484C is an ECP2-series field-programmable gate array with 48,000 logic elements, 6,000 LUTs, 396,288 bits of distributed RAM, and up to 339 user I/O in a 484-BBGA package. It operates from a 1.14 V to 1.26 V core supply and is identified as a 1.2 V, -6 speed-grade device. These headline parameters position it for programmable control, interface, signal-processing, and embedded systems requiring moderate logic density and extensive I/O. An FPGA is a programmable semiconductor whose digital logic, interconnect, and I/O behavior are defined after fabrication through a configuration bitstream. Within the product hierarchy, the LFE2-50E-6F484C is a field-programmable gate array, specifically a member of the Lattice ECP2 family and the broader integrated-circuit and semiconductor categories. Compared with a fixed-function ASIC, it permits design revisions, field updates, and adaptation to multiple hardware configurations without changing the PCB. Key features include a nominal 50,000-cell FPGA implementation, 6,000 LUTs, and 396,288 bits of distributed RAM. The device provides 339 user I/O according to distributor listings, making the 484-ball package suitable for designs that need more external connections than a smaller FPGA can offer. Its 1.2 V operating class supports low-voltage digital systems, while the -6 ordering code identifies the device's performance grade. The ECP2 architecture is intended to combine programmable logic with embedded memory resources in a single package. Distributed RAM can be used for buffers, lookup functions, small state machines, and data transformations without requiring external memory for every small storage requirement. The available verified sources do not state the exact number of DSP blocks, PLL count, supported I/O standards, maximum clock frequency, or internal memory organization, so these values must be confirmed in the manufacturer datasheet before design release. Typical uses include industrial automation, test and measurement, communications interfaces, embedded control, video or display control, and general-purpose signal processing. The large I/O count is particularly useful when a design must bridge multiple buses, converters, memories, LEDs, connectors, and communication transceivers while retaining a reconfigurable logic fabric. Designers should confirm power sequencing, decoupling, configuration interface requirements, ball assignments, and high-speed layout constraints against the official LatticeECP2/M family data sheet. Because the supplied web results do not expose a complete 484-ball pin map, the package drawing should not be inferred from a generic BGA layout. This page consolidates the verified distributor specifications, family-level substitute information, application guidance, and design cautions so engineers can compare the LFE2-50E-6F484C against pin-compatible ECP2 options without treating package similarity as proof of complete interchangeability.

LFE2-6E-5F256C

LFE2-6E-5F256C - 6K Lattice ECP2 FPGA, 190 I/O | Lattice

The Lattice Semiconductor LFE2-6E-5F256C is a 6,000-cell ECP2 field-programmable gate array with 190 user I/O, 56,320 RAM bits, and a 256-pin FBGA package, optimized for 1.2 V operation. It combines programmable logic, block RAM, and DSP resources in a reconfigurable semiconductor for embedded control, communications, and signal-processing systems. The device operates from 1.14 V to 1.26 V and is specified for a 0°C to 85°C operating junction-temperature range. An FPGA is a programmable digital integrated circuit that can be configured after manufacture to implement logic, state machines, interfaces, and parallel processing functions. The LFE2 family belongs to the broader field-programmable logic and semiconductor hierarchy. Compared with a fixed-function application-specific integrated circuit, an FPGA allows design changes to be implemented through configuration rather than a new silicon layout, making it useful for prototypes, industrial equipment, communications infrastructure, and embedded systems. The LFE2-6E-5F256C provides 6,000 logic elements organized into 750 logic array blocks and includes 56,320 total RAM bits. The verified distributor data identifies 190 user I/O, a 1.2 V supply class, and a 256-FPBGA package measuring 17 x 17 mm. These resources make the device suitable for designs requiring parallel control logic, moderate memory buffering, protocol bridging, and programmable digital signal processing. Lattice ECP2 devices are also positioned for designs that need flexible logic density without the scale of a larger FPGA. The 90 nm ECP2 implementation combines programmable logic with advanced DSP blocks; high-speed SERDES capability is associated with the ECP2M family rather than being assumed for every ECP2 member. For the LFE2-6E-5F256C specifically, design engineers should use the manufacturer datasheet and package documentation to confirm configuration, I/O standards, clocking, power, and exposed-ball assignments before layout. Typical applications include industrial control systems, communications and protocol interfaces, embedded instrumentation, audio and general digital signal processing, data acquisition front ends, and compact embedded processors. Its 190 I/O and 56,320 RAM bits allow the FPGA to connect external memory or peripherals while offloading time-critical logic from a host processor. The 256-pin FBGA footprint also requires careful PCB routing and thermal design because the dense package can make escape routing and power delivery more demanding than a leaded package. When selecting this device, match the FPGA logic, RAM, DSP, clock, I/O, speed-grade, temperature, and power requirements to the exact system specification. A different FPGA with a similar cell count may require different tools, configuration handling, package balls, or I/O standards. This page combines verified distributor specifications, package information, and application guidance; exact pricing and stock status must be confirmed for the current purchase date. This product-data summary is intended to make the LFE2-6E-5F256C searchable for FPGA selection, package matching, and replacement evaluation without implying that every similarly packaged FPGA is pin-to-pin compatible.

LFE2-6E-5F256I

LFE2-6E-5F256I - 6K LUT, 190 I/O ECP2 FPGA | Lattice

The Lattice Semiconductor LFE2-6E-5F256I is an ECP2 field-programmable gate array with 6,000 logic cells, 190 user I/O, a -5 speed grade, and a 1.2 V core supply in a 256-ball Fine Pitch Ball Grid Array package. It is designed for compact, parallel digital logic, control, interface, and signal-processing designs requiring programmable nonvolatile configuration and deterministic FPGA performance. A field-programmable gate array is a programmable semiconductor containing configurable logic blocks and programmable interconnect. An FPGA sits above basic fixed-function logic in the hardware hierarchy: programmable logic blocks can be connected by engineers after manufacture, allowing parallel datapaths, state machines, interfaces, and embedded control functions to be consolidated into one device. ECP2 devices combine this reconfigurable architecture with an industrial-temperature option and a high-I/O package. The verified distributor data identifies the device as an ECP2 FPGA with 6K logic cells, 190 I/O, a -5 speed designation, and a 1.2 V operating rail. DigiKey additionally lists 56,320 configuration bits and identifies the physical device as a 256-BGA package. The supplied Microchip USA result describes the package as 17 mm by 17 mm and notes 190 user I/O pins. Its snippet inconsistently states 750 lookup tables, so that value is not used as an authoritative specification. Lattice describes the ECP2/M family as optimized for advanced DSP blocks and, for ECP2M devices, high-speed SERDES. The exact DSP-block count, system frequency ranges, memory quantities, I/O standards, configuration interfaces, and power characteristics are not present in the supplied source text and therefore require confirmation from the complete manufacturer datasheet before design release. The 190-I/O count is especially useful for dense board-level integration, but users must assign pins according to the official package data and bank constraints. Typical uses include industrial control, data acquisition, communications gateways, embedded instrumentation, and parallel processing. The 256-ball package supports fine-pitch assembly but demands careful PCB layout, ball assignment, power-plane distribution, and signal-integrity control. The -5 suffix denotes the supplier-classified speed grade, while the final I suffix is reported by Partstack as an industrial temperature grade. For PCB design, use the manufacturer pinout and package drawing rather than generic BGA assumptions. Validate every power, ground, configuration, clock, and user-I/O ball against the current Lattice documentation. Confirm supported I/O standards and voltage domains before connecting external devices. This page synthesizes the supplied distributor records, package details, and replacement cross-references into an engineering-oriented procurement and selection summary.

LFE2-6E-5FN256I - 6K LUT FPGA, 190 I/O, 256-BGA | Lattice

The Lattice Semiconductor LFE2-6E-5FN256I is an ECP2 field-programmable gate array with 6,000 logic cells, 190 I/O, 1.2 V operation, and a 256-pin FBGA package. It is positioned for embedded systems that require reconfigurable logic, parallel interfaces, control functions, and moderate DSP processing in a compact surface-mount package. The -5 speed grade and industrial temperature designation identify this configuration for industrial operating conditions. An FPGA is a programmable semiconductor used to implement digital control, interface, timing, signal-processing, and data-path logic. Unlike a fixed-function application-specific integrated circuit, an FPGA can be reconfigured during development and can shorten the cycle between prototype and production. The ECP2 family belongs to Lattice Semiconductor's programmable-logic portfolio and is commonly used when design flexibility is more valuable than the very high logic density of a large FPGA. The LFE2-6E-5FN256I combines 6K LUTs, 190 I/O, 1.2 V supply operation, and embedded DSP capability in a 256-BGA package. The 190 I/O count supports connections to external memories, parallel buses, sensors, converters, and industrial peripherals. Its 1.2 V operating supply is suitable for systems designed around modern low-voltage digital logic. The -5 suffix identifies the speed grade, while the I suffix identifies the industrial temperature option. The FPGA architecture allows designers to implement parallel control logic, interface translation, data acquisition, and fixed-point signal-processing functions in one programmable device. This can reduce the number of supporting discrete logic components and allow firmware or configuration updates during product development. Designers must still account for I/O assignment, pin constraints, configuration memory, clocking, power integrity, and thermal performance in the PCB design. Typical uses include industrial automation, test and measurement, communications interfaces, embedded control, data acquisition, and compact embedded processing systems. The 256-BGA package is appropriate for multilayer PCB designs with adequate escape-routing capability and careful power delivery. It is not intended for a simple two-wire serial interface or a low-pin-count control-only design. When planning the layout, follow the manufacturer pinout and package guidelines, provide clean 1.2 V power rails, keep configuration and clock signals away from noisy analog or high-current switching paths, and validate all I/O standards against the target board voltage. This page summarizes the available LFE2-6E-5FN256I information, practical application fit, and same-package alternatives for engineering evaluation. The LFE2-6E-5FN256I is best selected when a 6K-logic ECP2 design needs 190 I/O, a 256-BGA footprint, and industrial-grade programmable logic. Compare speed-grade and package variants carefully, because a related MPN with a similar family name may not have identical electrical ratings, temperature coverage, or pin compatibility.

It is positioned for programmable logic, control, interface, and embedded digital systems where a compact, high-pin-count FPGA is required. An FPGA is a programmable digital integrated circuit whose logic and interconnect resources can be configured after manufacture. In the broader hierarchy, an FPGA belongs to programmable logic devices and sits above basic logic gates but below application-specific processors and systems. The LatticeECP2 family provides configurable logic blocks, programmable routing, dedicated resources, and I/O structures for parallel and serial digital designs. The LFE2-6E-5T144C combines 6,000 LUTs with 90 I/O in a 144-lead LQFP package. The -5 designation is associated with a -5 speed grade in the distributor listings, while the package code and gull-wing terminal description identify a 144-terminal surface-mount FPGA. The exact core voltage, operating-temperature range, embedded-memory configuration, block-resource quantities, and pin functions were not included in the supplied verified data and are therefore not inferred here. Typical design uses include industrial control logic, data-acquisition front ends, communications-interface bridges, instrumentation, embedded test equipment, and general-purpose digital prototyping. The 90-I/O count can be valuable when a design requires multiple parallel buses, control signals, or high-speed external interfaces. Designers should still confirm pin availability, voltage standards, and timing constraints against the official Lattice ECP2 documentation before schematic capture. A key design consideration is power planning. The distributor result identifies a 1.2 V FPGA, but the supplied data does not state core current, I/O current, power consumption, junction temperature, or thermal resistance. Those values must be taken from the manufacturer datasheet and the actual switching activity of the implemented design. Decoupling, ground-plane continuity, and pin-compatible replacement verification remain essential during PCB implementation. This page consolidates the verified distributor identity, package information, device resource summary, availability links, and engineering-oriented application context. It distinguishes documented facts from parameters that require confirmation from the Lattice Semiconductor datasheet rather than estimating values.

The I suffix identifies the industrial-temperature offering, while the -5 speed grade and 144-pin package support designs requiring deterministic programmable logic in industrial embedded systems. A field-programmable gate array, or FPGA, is a programmable semiconductor used to implement control logic, interfaces, protocol handling, datapaths, and DSP functions after board fabrication. Within the broader semiconductor hierarchy, an FPGA combines configurable logic blocks, programmable interconnect, block RAM, and I/O resources. This makes it useful when a design requires rapid revisions, parallel channels, mixed logic functions, or a compact controller that would otherwise require several fixed-function devices. The verified product data identifies 6K LUTs, 90 I/O, 56,320 RAM bits, and a 1.2 V operating class. A 144-TQFP package provides 144 physical leads and a surface-mount form factor suitable for automated PCB assembly. The available listing data also reports 90 I/O and a 144-TQFP package, while detailed pin assignments, block counts, pin standards, and configuration interface details require the manufacturer datasheet before layout or replacement approval. Typical ECP2 applications include industrial control, instrumentation, embedded communication, motion-control logic, and general-purpose programmable signal conditioning. The programmable architecture lets designers consolidate parallel control functions into one FPGA, while the 90 I/O count supports external memory, converters, communications transceivers, status indicators, and actuator or sensor interfaces. Designers should verify voltage tolerances and pin multiplexing against the device-specific pinout rather than relying only on the package name. For robust implementation, begin with the manufacturer pinout and power specifications, then define bank voltage constraints before assigning external interfaces. Place decoupling capacitors close to every supply pin, preserve the package footprint and exposed thermal requirements specified by the manufacturer, and program the device using the supported Lattice toolchain. A hardware replacement is valid only after checking pinout, I/O standards, supply rails, timing, configuration interface, and temperature grade.

The 144-pin package provides more I/O than smaller ECP2 options while retaining a surface-mount form factor. An FPGA is a user-programmable semiconductor in the broader semiconductor and digital-logic hierarchy. Unlike a fixed-function application-specific integrated circuit, an FPGA allows logic, interfaces, and processing functions to be configured after manufacture. ECP2 devices combine LUT-based logic, block RAM, programmable I/O, and DSP resources in a single silicon platform. This makes the LFE2-6E-5TN144C suitable for designs where algorithms, protocols, or control logic must be adapted without changing the physical PCB. The device offers 6,000 logic cells, 90 I/O, 56,320 RAM bits, and a 1.2 V core voltage.

The 90 available I/O support communication ports, control signals, status indicators, and external memory or sensor interfaces. The -5 speed designation identifies the device’s manufacturer speed grade, while the TN144C suffix identifies its commercial-temperature and 144-pin package configuration. The LFE2-6E-5TN144C belongs to the ECP2 family, a compact FPGA architecture intended for low-cost embedded applications with modest logic requirements. Designers can implement state machines, bus interfaces, protocol conversion, digital filtering, and control logic in one device. Embedded RAM can retain data buffers and state, while DSP blocks can accelerate suitable arithmetic pipelines. The 1.2 V core keeps the device aligned with modern low-voltage digital systems and allows the FPGA to share nearby supply rails when its I/O and configuration requirements permit. Typical applications include industrial control and data acquisition, communications-interface bridging, embedded sensor processing, compact audio or control subsystems, and general-purpose digital logic prototyping. Its 90 I/O are especially useful when an implementation must connect multiple sensors, actuators, communications ports, and status signals without adding another large programmable-logic package. A key design consideration is I/O planning. Because the device has 144 physical positions but only 90 user I/O, not every package position is a general-purpose user pin. Use the manufacturer pin-description table and device documentation when assigning banks, dedicated configuration pins, power pins, and ground pins. PCB design must also preserve the ECP2 configuration interface and provide a deterministic startup path for reliable field operation. This page consolidates the verified resource counts, package information, sourcing links, compatible ECP2 alternatives, comparison parameters, and application-focused design guidance.

The LFE2-6E-6F256C belongs to the LatticeECP2 family. Its large I/O count can simplify board-level connections when the design uses multiple buses, parallel data interfaces, or multiple external peripherals. The 55 Kb block RAM figure applies explicitly to the verified LFE2-6E-6FN256C family member; the supplied search data does not state that figure for LFE2-6E-6F256C, so that value is not used as a target specification here. For a new board, engineers should verify power rails, configuration interface support, I/O standards, pin constraints, and the exact package drawing before layout. Because the available evidence confirms 256 FBGA and 190 I/O but does not provide a complete manufacturer pin table, detailed ball assignments and electrical limits should be taken from the official Lattice documentation rather than inferred from distributor summaries.

The ECP2 architecture combines programmable logic with embedded block RAM for designs requiring both control logic and local data storage. A 357 MHz maximum frequency is reported in the supplied component listing, making timing closure an important consideration for clocked datapaths. Because this device belongs to a mature FPGA family, engineers can use its configuration ecosystem and established design flows rather than developing fixed application-specific logic. Typical uses include industrial control and automation, communication interfaces, test and measurement equipment, embedded video or display control, and peripheral expansion for microcontrollers or processors. The 190 I/O are useful for parallel buses, status and control signals, and multi-bit data interfaces, while the embedded RAM can support buffers, packet processing, or state-holding functions. PCB design requires careful BGA fanout, differential-pair routing, ground-plane continuity, and decoupling around the 1.2 V supply rails. Designers should obtain the manufacturer pinout and power-decoupling guidance before routing the 256-ball footprint. Configuration programming and signal-integrity verification should also be included in the design plan rather than treated as late board-layout steps. This page consolidates the verified device specifications, current distributor information, package details, and same-family drop-in alternatives. It also adds application guidance and engineering checks that are not presented as a single manufacturer-datasheet conclusion, helping teams compare speed grades, temperature options, and package-compatible alternatives before committing to a PCB design.

LFE2-6E-6T144C - 6K LUT, 90 I/O FPGA | Lattice Semiconductor

The Lattice Semiconductor LFE2-6E-6T144C is an ECP2 field-programmable gate array with 6K LUTs, 90 I/O, 6,320 logic cells, and a 144-pin TQFP package. Its 1.2 V core and -6 speed grade make it a compact programmable-logic device for embedded control, interface bridging, signal conditioning, and industrial automation. The verified distributor listing identifies the device as a LatticeECP2 FPGA manufactured using 90 nm technology and supplied in a tray package. A field-programmable gate array is a semiconductor whose configurable logic and interconnect resources implement digital functions after fabrication. An FPGA occupies the programmable-logic portion of the wider semiconductor hierarchy, above fixed-function logic ICs and below application-specific programmable systems. The ECP2 family combines programmable logic blocks, memory resources, digital signal processing capability, and general-purpose I/O in one reconfigurable device. This makes the LFE2-6E-6T144C useful when design rules change faster than a custom ASIC can be produced. Key features include 6K LUTs, 6,320 cells, 90 I/O, a 1.2 V supply, and a -6 speed designation. The 144-pin TQFP package provides 144 external terminals in a surface-mount gull-wing format. Verified web results describe the part as an ECP2 FPGA with DSP capability, but detailed block counts, I/O standards, memory parameters, and timing values were not supplied in the retrieved evidence. Those values should therefore be confirmed against the manufacturer datasheet before a design is released. The part’s architecture is appropriate for glue-logic implementations, protocol conversion, control-plane logic, parallel data acquisition, and compact embedded systems. Its 90 I/O count can reduce the need for external programmable peripherals when the board-level pin budget is constrained. The -6 designation identifies the manufacturer’s speed grade, while the commercial C suffix appears in the ordering code; the retrieved evidence does not provide the exact commercial-temperature limits. Typical uses include industrial controllers, sensor aggregation modules, test equipment, embedded communications bridges, and compact control systems. A 1.2 V FPGA core simplifies power partitioning when the surrounding board already includes a 1.2 V rail, but external interface voltage levels must be selected independently and checked against the actual I/O specifications. The 144-pin package is larger than common QFN options, so PCB area and routing resources must be included in the mechanical design. For a new board, place the FPGA close to its clocks, decoupling network, configuration interface, and high-speed I/O routes. Keep power and ground connections short, follow the manufacturer’s recommended land pattern, and validate signal integrity for any external interface. This page consolidates verified distributor specifications, procurement information, replacement analysis, and engineering guidance rather than repeating only the part-number description.

LFE2-6E-6T144I - 6K LUT FPGA, 90 I/O, 1.2 V | Lattice

The Lattice Semiconductor LFE2-6E-6T144I is an ECP2 series field-programmable gate array with 6,000 logic cells, 90 I/O, and 56,320 RAM bits in a 144-LQFP surface-mount package. The verified product data identifies a 1.2 V device with a -6 speed designation and an industrial temperature option encoded by the part number. Its architecture combines programmable logic resources, block RAM, and dedicated DSP capability in a compact programmable-logic device suited to embedded control, signal processing, communications, and industrial equipment. An FPGA is a reconfigurable digital semiconductor that contains configurable logic blocks and programmable interconnect. Unlike a fixed-function microcontroller or application-specific integrated circuit, an FPGA can be programmed after manufacture to implement control logic, data paths, interfaces, and algorithms. The ECP2 family belongs to the broader FPGA and programmable-logic hierarchy, combining flexible parallel hardware with configuration-based design updates. The LFE2-6E-6T144I provides 6K logic elements, 90 I/O, and 56,320 RAM bits according to DigiKey and Mouser results. One supplier result also identifies 750 logic array blocks or configurable logic blocks, while the available data reports a 1.14 V to 1.26 V supply range and an operating junction temperature beginning at -40 °C. The -6 speed grade identifies the device speed option, but the supplied data does not establish the complete timing table, configuration interface details, or absolute maximum ratings. Typical uses include industrial control logic, sensor and acquisition systems, communications interface aggregation, low-power signal processing, and embedded instrumentation. The 90-I/O count provides substantial board-level connectivity for buses, status signals, control outputs, and external interfaces. The 56,320 RAM bits can support buffering, packet storage, counters, and small data tables, while the FPGA architecture allows parallel operations without relying on sequential processor execution. When designing around this device, verify the exact pinout, configuration memory interface, clock requirements, supported I/O standards, and bank voltage constraints in the LatticeECP2/M family data sheet. Do not infer pin compatibility solely from a matching package. The supplied search data supports the core resource and package claims, but not a complete manufacturer-qualified replacement list. This page combines verified distributor specifications, application guidance, and design cautions for engineers evaluating the LFE2-6E-6T144I. It distinguishes documented facts from unavailable parameters so procurement and hardware decisions can be made without inventing electrical or timing data.
