LFE2-6E-6TN144I
LFE2-6E-6TN144I - 6K LUT ECP2 FPGA | Lattice
Lattice Semiconductor LFE2-6E-6TN144I is an ECP2 field-programmable gate array with 6,000 logic cells, a 90 I/O interface, a 1.2 V core supply, and a 144-pin LQFP package. The -6 speed designation identifies the performance grade, while the industrial-temperature suffix supports applications requiring extended environmental operation. Its 90 nm programmable-logic process combines configurable logic, block RAM, and DSP resources in a low-cost device family designed for embedded control, communications, industrial automation, and general-purpose digital logic.
An FPGA is a programmable-logic semiconductor whose digital function is defined by loading a configuration bitstream into on-chip memory. Within the semiconductor hierarchy, the LFE2-6E-6TN144I belongs to the ECP2 family of field-programmable gate arrays, placing it below programmable logic devices and above fixed-function logic integrated circuits. This distinction allows one PCB design to support firmware-driven changes in timing, interfaces, control algorithms, or system behavior without replacing the physical device.
The device provides 6,000 logic cells and 90 user I/O in a surface-mount 144-pin LQFP package measuring 20 mm by 20 mm. A 1.2 V core operating voltage supports low-power logic implementation, and the -6 speed grade targets designs requiring more timing margin than slower ECP2 grades. The 90 I/O count is particularly useful for parallel control, data acquisition, industrial interfaces, and board-level integration where a programmable device must directly connect to multiple external signals.
The ECP2 architecture provides programmable logic together with dedicated block RAM and DSP resources, allowing designers to implement control logic, counters, state machines, data pipelines, signal conditioning, and fixed-point processing in one device. The manufacturer classifies the part in the ECP2 family and identifies 6,000 cells, a 144-LQFP package, 90 I/O, and a 90 nm process node. This combination provides a practical platform for moderately complex digital systems where a small microcontroller is insufficient or an application-specific ASIC would not justify the development cost.
Typical uses include industrial automation controllers, sensor and measurement interfaces, communication equipment, embedded data acquisition, motor and machine-control logic, and general-purpose digital signal conditioning. Its 90 I/O can simplify board partitioning when multiple buses, discrete inputs, and outputs must be consolidated. The 20 mm by 20 mm LQFP also remains practical for conventional multilayer PCB assembly methods rather than requiring fine-pitch BGA assembly.
Designers should confirm the exact pin assignments, supported I/O standards, configuration requirements, clocking resources, and recommended power and decoupling networks against the manufacturer ECP2 documentation before layout release. Pay particular attention to the -6 speed designation, 1.2 V core supply, industrial-temperature ordering code, and package pinout. Configuration storage, JTAG access, programming voltage, and unused-pin treatment must also be validated for the selected board architecture.
This product page combines the exact ECP2 ordering information with practical selection guidance, alternative cross-references, parameter comparisons, and design-oriented implementation notes. These resources help engineers identify whether the LFE2-6E-6TN144I fits the required logic density, I/O count, package, speed grade, and environment before beginning a new programmable-logic design.
