LFECP20E-3FN484C

The LFECP20E-3FN484C is a Lattice ECP‑family Field Programmable Gate Array (FPGA) in a 484‑ball FPBGA package. The device combines an efficient FPGA fabric with dedicated high‑performance functions to address mainstream, cost‑sensitive FPGA applications.

With a midrange logic capacity, embedded memory and dedicated DSP resources, this commercial‑grade device is suitable for designs that require configurable logic, high I/O counts and integrated memory/DDRsupport capabilities within a compact surface‑mount package.

Key Features

• Logic Capacity  Approximately 19,700 logic elements (logic cells) providing a midrange implementation capacity for user logic and glue functions.
• On‑chip Memory  Approximately 0.43 Mbits (434,176 bits) of total on‑chip RAM for embedded and distributed memory requirements.
• Dedicated DSP Resources  6 sysDSP blocks on the LFECP20 device, supporting up to 24 18×18 multipliers for multiply‑accumulate and signal‑processing tasks.
• I/O and Interface Flexibility  360 user I/Os with programmable sysI/O buffer support for a wide range of standards including LVCMOS (1.2–3.3 V), LVTTL, SSTL, HSTL, PCI, LVDS, LVPECL and RSDS.
• Memory Interface Support  Dedicated DDR memory support and on‑chip resources to implement DDR interfaces (device family supports DDR implementations up to DDR400 as described in family documentation).
• Clocking  Up to four analog PLLs per device to enable clock multiply, divide and phase shifting for system timing requirements.
• Power  Core supply range specified at 1.14 V to 1.26 V (nominal 1.2 V operation).
• Package and Mounting  484‑ball FPBGA (23 × 23 mm) surface‑mount package optimized for high I/O count in a compact footprint.
• Commercial Grade Operation  Operating temperature range 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Cost‑sensitive embedded systems  Midrange logic and on‑chip RAM provide configurable control and interface functions for space‑ and cost‑constrained products.
• Signal processing and DSP  sysDSP blocks and multiple multipliers enable on‑device multiply‑accumulate workloads for filtering, transform and other DSP tasks.
• Memory interface controllers  Dedicated DDR support and flexible I/O make the device suitable for implementing DDR interfaces and memory controllers.
• High‑I/O protocol bridging  360 I/Os and wide I/O standard support enable protocol translation, parallel buses and mixed‑I/O systems integration.

Unique Advantages

• Balanced logic and memory resources: ~19,700 logic elements with approximately 0.43 Mbits of on‑chip RAM to support both control logic and state/data buffering in a single device.
• Integrated DSP acceleration: Six sysDSP blocks offering multiple 18×18 multipliers to offload compute‑intensive math from external processors.
• High I/O density in a compact package: 360 I/Os in a 23 × 23 mm 484‑ball FPBGA for designs requiring large numbers of external connections without a large PCB footprint.
• Flexible interface support: Programmable I/O buffers that support a broad set of standards (LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS, LVPECL, RSDS) to simplify system integration.
• Robust clocking capabilities: Up to four analog PLLs for clock generation, multiplication, division and phase shifting to meet diverse timing needs.
• Design ecosystem support: Family documentation references design tools and pre‑designed IP to accelerate implementation and migration across the LatticeECP family.
