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.
