LFEC3E-3QN208C

The LFEC3E-3QN208C is a commercial-grade EC family FPGA from Lattice Semiconductor, offered in a 208‑BFQFP / 208‑PQFP (28 × 28 mm) surface-mount package. It delivers a balance of logic density, embedded memory and flexible I/O for mainstream commercial and embedded digital designs.

Built on the LatticeECP/EC family architecture, the device targets cost-sensitive, mainstream applications that require a programmable fabric with integrated memory, configurable I/O and system-level features for interface and timing management.

Key Features

• Logic Capacity — 3,100 logic elements (LEs) providing moderate programmable logic resources for glue logic, protocol bridging and control functions.
• Logic Structure — 384 PFUs/PFFs (as indicated in product specifications for this family), supporting efficient placement and routing of logic.
• On‑Chip Memory — Approximately 55 Kbits of embedded RAM (56,320 bits total) for FIFOs, buffering and small data storage inside the FPGA.
• I/O Count and Flexibility — 145 user I/Os in the 208‑pin BFQFP package, compatible with a range of parallel and serial interface options described in the family datasheet.
• Power — Core supply range 1.14 V to 1.26 V, matching the family’s 1.2 V nominal core requirements.
• Clocking and Timing — Up to two analog PLLs (per family data) for clock multiply/divide and phase shifting to support diverse timing requirements.
• Memory Interface Support — Family-level support includes dedicated DDR memory interface logic (up to DDR400), enabling external memory connectivity where required.
• System and Development Support — Family documentation highlights IEEE 1149.1 boundary scan, SPI boot flash interface and ispTRACY internal logic analyzer capability for debug and system bring‑up.
• Package and Mounting — 208‑BFQFP (supplier package noted as 208‑PQFP 28×28) in surface mount format; RoHS compliant.
• Operating Range — Commercial temperature grade with an operating range of 0 °C to 85 °C.

Typical Applications

• Embedded Systems — Implement custom control logic, protocol translation and on‑board data handling where moderate logic and embedded RAM are required.
• Interface Bridging — Bridge between disparate digital interfaces using the device’s flexible I/O and family-supported interface standards.
• Memory Interface and Buffering — Use embedded RAM and family DDR interface support for intermediate buffering and memory controllers in cost-sensitive designs.
• Prototyping and Development — Evaluate system architectures or validate custom logic with available design‑tool support and on‑chip debug capabilities.

Unique Advantages

• Balanced Logic and Memory: 3,100 logic elements combined with approximately 55 Kbits of embedded RAM provides a compact platform for integrated control and buffering tasks.
• High I/O Count in a Compact Package: 145 user I/Os in a 208‑pin BFQFP footprint enable rich external connectivity without larger BGA packages.
• Low‑Voltage Core: Narrow core supply range (1.14–1.26 V) aligns with the family’s 1.2 V architecture for predictable power design.
• System-Level Features: Integrated support for boundary scan, SPI boot flash and internal logic analysis simplifies development and system integration.
• Commercial Grade and RoHS Compliant: Designed for commercial temperature ranges (0 °C to 85 °C) and RoHS compliance for regulated supply chains.
• Design Ecosystem: Family documentation references ispLEVER tools and pre‑designed IP modules to accelerate development and migration within the LatticeECP/EC family.
