LFECP20E-3FN672I

The LFECP20E-3FN672I is a LatticeECP-family Field Programmable Gate Array (FPGA) optimized for mainstream, cost-conscious designs that require substantial I/O and on-chip resources. This industrial-grade device combines a dense logic fabric with embedded memory and dedicated DSP resources to support data buffering, signal processing and high‑pin-count interfaces.

Targeted at embedded and industrial applications, the device offers a broad set of system features derived from the LatticeECP architecture, delivering integration and flexibility for designs that demand plentiful I/O, on-chip RAM and clocking resources.

Key Features

• Programmable Logic — 19,700 logic elements providing the configurable fabric required for complex control and processing functions.
• Embedded Memory — Approximately 434 Kbits of on-chip RAM (434,176 bits) for frame buffering, packet queues and local data storage.
• High I/O Count — 400 I/Os to support dense connectivity and multiple high‑speed interfaces without extensive external logic.
• Dedicated DSP Resources — Family-level sysDSP blocks available (LatticeECP family mapping: 6 sysDSP blocks for this density) and associated multipliers to accelerate multiply‑accumulate workloads.
• Flexible I/O Standards — LatticeECP family I/O buffer programmability supports a wide range of interfaces and levels (LVCMOS, LVTTL, SSTL, HSTL, LVDS and others) to simplify system-level interfacing.
• Clocking — Up to four analog PLLs per device (family capability) enable clock multiplication, division and phase shifting for flexible timing architectures.
• Power — Core supply range 1.14 V to 1.26 V as specified for the device.
• Package & Mounting — 672‑ball fpBGA in a 27×27 mm footprint (672-FPBGA); surface-mount packaging for compact board integration.
• Operating Range — Industrial temperature grade with an operating range of −40°C to 100°C.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Implement motor control, sensor aggregation and deterministic I/O handling using the device’s logic density, DSP resources and industrial temperature rating.
• Data Buffering and Protocol Bridging — Use the on-chip RAM and plentiful I/Os for packet buffering, protocol conversion and interface bridging in embedded networking subsystems.
• Signal Processing — Leverage the family’s sysDSP blocks and multipliers for real-time filtering, accumulation and processing tasks in instrumentation or imaging pipelines.
• High‑Pin‑Count Embedded Systems — Integrate multiple peripherals and buses directly to the FPGA’s 400 I/Os to minimize external glue logic and simplify board-level routing.

Unique Advantages

• High integration density: Nearly 20k logic elements and significant on-chip RAM reduce the need for external memories and glue devices, shrinking BOM and board area.
• DSP-accelerated processing: Built-in sysDSP capability and multipliers accelerate math-intensive tasks and reduce load on external processors.
• Flexible interfacing: The family’s programmable I/O buffer support enables direct connection to a broad set of signaling standards, simplifying interface design.
• Robust clock management: Multiple PLLs support complex clocking schemes for multi-domain systems and high-speed interfaces.
• Industrial temperature support: Rated for −40°C to 100°C operation, suitable for harsh environments and extended-temperature deployments.
• Compact, high‑pin package: The 672‑ball fpBGA (27×27 mm) provides high pin density in a compact surface-mount form factor for space-constrained boards.
