LFEC20E-4F484C

The LFEC20E-4F484C is a commercial-grade, field programmable gate array (FPGA) from Lattice Semiconductor Corporation designed for general-purpose digital logic integration. It combines a mid-density logic fabric with embedded memory and abundant I/O to support a range of commercial embedded and communications applications.

With 19,700 logic elements, approximately 0.434 Mbits of embedded memory and 360 I/O pins in a compact 484-ball BGA package, this device targets designers who need flexible programmable logic, moderate on-chip RAM and a high I/O count in a surface-mount package.

Key Features

• Logic Capacity — 19,700 logic elements for custom digital functions, state machines and glue-logic integration.
• Embedded Memory — Approximately 0.434 Mbits of on-chip RAM to support buffering, small FIFOs and local data storage.
• I/O Count — 360 user I/O pins to support multiple interfaces, parallel buses and wide peripheral connectivity.
• Package & Mounting — 484-BBGA (supplier device package: 484-FPBGA, 23×23) in a surface-mount form factor for compact PCB layouts.
• Power — Core voltage supply range from 1.14 V to 1.26 V for defined power domain planning.
• Operating Range & Grade — Commercial-grade device rated for 0 °C to 85 °C operating temperature.
• Environmental Compliance — RoHS compliant for lead-free manufacturing processes.

Typical Applications

• Consumer & Commercial Embedded Systems — Implement custom control logic, peripheral interfaces and integration tasks using the device's logic density and I/O resources.
• Communications Equipment — Use the FPGA for protocol bridging, data path control and interface aggregation where flexible logic and plentiful I/O are required.
• Prototyping and Development — Rapidly validate digital designs and iterate on custom logic within a mid-density programmable fabric.
• Instrumentation & Test — Implement custom signal routing, control logic and local buffering using on-chip RAM and abundant I/O.

Unique Advantages

• Balanced Logic and Memory: 19,700 logic elements paired with approximately 0.434 Mbits of embedded memory provide a practical balance for many control and data-path functions without external RAM.
• High I/O Integration: 360 I/O pins simplify board-level interfacing and reduce the need for additional I/O expanders.
• Compact Surface-Mount Package: The 484-BBGA / 484-FPBGA (23×23) package supports dense PCB layouts while maintaining robust pin count.
• Defined Power Envelope: A core voltage range of 1.14 V to 1.26 V helps with power budgeting and supply design.
• Commercial Temperature Support: Rated for 0 °C to 85 °C operation to match typical commercial product environments.
• RoHS Compliant: Conforms to lead‑free manufacturing requirements for commercial production.
