LFEC1E-3QN208C

The LFEC1E-3QN208C is an EC-family field programmable gate array (FPGA) from Lattice Semiconductor designed for mainstream, cost-sensitive digital designs. It provides a compact, surface-mount FPGA implementation with a balance of logic capacity, on-chip memory and I/O to support embedded control, interface bridging and general-purpose programmable logic tasks.

Built on the LatticeECP/EC architecture, the device targets applications that require flexible I/O, low-voltage core operation and commercial-temperature operation while minimizing board space and overall system BOM.

Key Features

• Core Logic — Approximately 1,500 logic elements and 192 logic blocks provide the configurable fabric for glue logic, state machines and control functions.
• On-chip Memory — Total RAM of 18,432 bits (~18 Kbits) suitable for small FIFOs, register files and buffering in control and interface applications.
• I/O Capacity & Flexibility — 112 I/Os available in the 208-pin package to support multiple parallel interfaces, GPIO and peripheral connections.
• Power Rail — Core voltage supply range from 1.14 V to 1.26 V (nominal 1.2 V), enabling integration into low-voltage systems.
• Clocking — Family documentation indicates integrated PLL support; the LFEC1-class device includes 2 PLLs for clock management and deskewing.
• Package & Mounting — 208-BFQFP (208-pin PQFP, 28 × 28 mm) surface-mount package for compact board-level integration.
• Operating Range — Commercial temperature grade: 0 °C to 85 °C, suitable for consumer and many industrial/business environments where commercial-grade components are specified.
• Compliance — RoHS compliant, meeting common environmental requirements for lead-free assembly.
• System-Level Support (Family) — LatticeECP/EC family-level features include SPI boot flash interface, IEEE 1149.1 boundary scan and support in the ispLEVER tool suite for synthesis and place-and-route workflows.

Typical Applications

• Embedded Control — Implement real-time control logic, glue logic and protocol translators for consumer and commercial equipment.
• Interface & I/O Expansion — Provide parallel and serial I/O aggregation, bus bridging and custom peripheral interfacing using the device’s 112 I/Os.
• Memory Interface & Buffering — Use on-chip RAM and clocking resources for temporary buffering and data path alignment in systems that require compact memory handling.
• Prototyping & Low-Cost FPGA Designs — Ideal for developers targeting low-cost, small-package FPGA implementations in evaluation and production of mainstream applications.

Unique Advantages

• Right-sized Logic Capacity: ~1,500 logic elements provide a practical balance of capability and cost for modest FPGA designs without excessive device overhead.
• Generous I/O Count: 112 I/Os in a 208-pin PQFP package simplify board routing and reduce the need for external I/O expanders.
• Low-Voltage Core Operation: 1.14 V–1.26 V supply range aligns with modern low-voltage system architectures and reduces core power consumption.
• Compact Surface-Mount Package: 208-BFQFP (28 × 28 mm) provides a small footprint solution for space-constrained PCBs while maintaining robust pin density.
• Design Ecosystem: Supported by the LatticeECP/EC family tools and features (boundary scan, SPI boot), easing integration into established development flows.
• RoHS Compliance: Meets common lead-free assembly requirements for commercial products.
