LFECP20E-4FN484C

The LFECP20E-4FN484C is a commercial-grade ECP-family Field Programmable Gate Array from Lattice Semiconductor. It combines a mid-range logic fabric with substantial on-chip memory and a high I/O count in a compact 484-ball BGA package for mainstream, cost-sensitive FPGA designs.

This device is suited for applications that require a balance of logic capacity, embedded memory and flexible interfaces — delivering approximately 19,700 logic elements, around 0.43 Mbits of embedded memory, and 360 user I/Os while operating from a 1.14 V to 1.26 V supply.

Key Features

• Logic Capacity — Approximately 19,700 logic elements to implement medium-complexity digital designs.
• Embedded Memory — Total on-chip RAM of 434,176 bits (approximately 0.43 Mbits / ≈424 Kbits) for data buffering and local storage.
• I/O Density — 360 user I/Os in a 484-ball BGA package (484-FPBGA, 23 × 23 mm) to support wide peripheral and bus connectivity.
• Dedicated DDR Memory Support — Family-level support for DDR interfaces up to DDR400 (200 MHz) for system memory interfacing needs.
• sysDSP™ Acceleration (Family) — Lattice ECP family devices offer dedicated DSP resources (family range: 4 to 8 sysDSP blocks) for high-performance multiply-accumulate operations.
• Flexible I/O Standards (Family) — Programmable I/O buffers support a broad set of interfaces including LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS and related standards (as provided by the family data sheet).
• Clocking — Family-level support for up to four analog PLLs for clock multiply/divide and phase-shifting functions.
• Package & Mounting — Surface-mount 484-BBGA package (supplier package: 484-FPBGA, 23 × 23 mm) for dense board layouts.
• Power & Temperature — Operates from 1.14 V to 1.26 V supply and rated for commercial operation from 0 °C to 85 °C.
• Regulatory — RoHS compliant for environmental compatibility.

Typical Applications

• Data and Interface Bridging — High I/O count and flexible I/O standards make the device suitable for bridging multiple buses and peripheral interfaces in embedded systems.
• DDR Memory Controllers & Buffers — Built-in family-level DDR support enables implementation of memory interfaces and buffering for mid-performance systems.
• Signal Processing Acceleration — Family sysDSP blocks and embedded RAM support multiply-accumulate and local data storage for DSP tasks and hardware accelerators.
• Cost-Sensitive Embedded Systems — Balanced logic, memory and I/O in a compact BGA package fits mainstream embedded and consumer designs where cost and integration matter.

Unique Advantages

• Balanced Integration: Combines nearly 19,700 logic elements with substantial on-chip RAM to reduce external memory needs and simplify board BOM.
• High I/O Count in Compact Package: 360 I/Os in a 23 × 23 mm fpBGA footprint supports complex connectivity without a larger package.
• Family-Level DSP & Clocking: Access to sysDSP blocks and up to four PLLs enables efficient implementation of timed and compute-heavy functions.
• Commercial Temperature Rating: Rated 0 °C to 85 °C for reliable operation in standard commercial environments.
• Low-Voltage Operation: Narrow supply range (1.14 V to 1.26 V) aligns with modern low-voltage system designs.
• RoHS Compliant: Environmentally compliant manufacturing and supply chain compatibility.
