LFXP20E-4F484C

The LFXP20E-4F484C is a non-volatile XP family Field Programmable Gate Array (FPGA) from Lattice Semiconductor, offering a high-density, reconfigurable logic fabric with on-chip memory and extensive I/O. It targets systems that require instant-on behavior, flexible interfacing and in-field reconfiguration while maintaining a compact 484‑ball BGA footprint.

With 20,000 logic elements and 340 I/Os in a 484-BBGA package, this device is suited for designs that need significant routing and memory resources, programmable I/O standards, and system-level features such as PLLs and internal configuration options.

Key Features

• Core and Logic  20,000 logic elements and 2,464 PFU/PFF units provide the programmable resources required for complex logic implementations.
• On‑chip Memory  Approximately 0.405 Mbits of total on-chip RAM, backed by distributed memory and embedded SRAM block resources.
• High‑Density I/O  Up to 340 I/Os with a programmable sysIO buffer supporting a wide range of standards including LVCMOS (3.3/2.5/1.8/1.5/1.2), LVTTL, SSTL, HSTL, PCI, LVDS, LVPECL and RSDS.
• Configuration and Security  Non‑volatile, instant-on architecture with no external configuration memory required and design security that prevents bitstream interception.
• In‑field Reconfiguration  TransFR™ Reconfiguration (TFR) enables reconfiguration of SRAM‑based logic while the system remains operational for flexible field updates.
• Low‑Power Modes  Sleep mode support enables substantial static current reduction (up to 1000× reduction under sleep), helping reduce standby power.
• Clocking  Up to four analog PLLs on the device for clock multiply, divide and phase shifting to support varied timing domains.
• Memory Interface Support  Dedicated DDR memory support (up to DDR333/166 MHz) for designs that require external high‑speed memory interfaces.
• Package and Mounting  484‑BBGA package (supplier package: 484‑FPBGA, 23×23 mm) with surface‑mount installation for compact, high‑I/O density PCB layouts.
• Operating Range and Compliance  Commercial grade device with operating temperature 0 °C to 85 °C, core voltage supply 1.14 V to 1.26 V, and RoHS compliance.
• System Level Tools  IEEE 1149.1 boundary scan, ispTRACY internal logic analyzer capability and onboard oscillator options for configuration and debug.

Typical Applications

• Instant‑on embedded systems  Systems that require immediate availability on power‑up benefit from the device’s non‑volatile instant‑on architecture and lack of external configuration memory.
• Memory interface controllers  Designs implementing external DDR memory can use the dedicated DDR support (up to DDR333) and on‑chip PLLs for timing management.
• High‑I/O signal processing  Applications needing a large number of I/Os and mixed signaling standards (LVDS, PCI, SSTL, HSTL, etc.) can use the programmable sysIO buffers for protocol flexibility.
• Field‑upgradeable logic  Products requiring in-field updates while operating can leverage TransFR™ reconfiguration to update logic without full system downtime.

Unique Advantages

• Non‑volatile instant‑on: Powers up in microseconds without external configuration memory, simplifying system startup and reducing component count.
• High integration: 20,000 logic elements with substantial embedded RAM consolidate logic and memory, lowering PCB BOM and board area.
• Flexible I/O standards: Programmable sysIO supports a broad set of interface standards, enabling multi‑protocol designs from a single device.
• In‑field reconfiguration: TransFR™ capability allows live updates to SRAM‑based logic for maintenance and feature upgrades in deployed systems.
• Low standby power: Sleep mode can reduce static current by up to 1000×, helping meet low‑power system requirements.
• Compact, high‑I/O package: 484‑ball BGA (23×23 mm) delivers maximum I/O density for space‑constrained PCBs.
