LFXP20E-3FN256I

The LFXP20E-3FN256I is a LatticeXP family Field Programmable Gate Array (FPGA) in a 256-ball fpBGA (17 × 17 mm) package. It provides 20,000 logic elements, approximately 0.4 Mbits of embedded RAM, and 188 I/Os in a surface-mount package engineered for industrial temperature operation. The device is designed for system designs that require integrated non-volatile configuration, flexible I/O support and in-field reconfiguration ability.

Key Features

• Core Architecture — 20,000 logic elements suitable for mid-density FPGA implementations; family architecture supports non-volatile, infinitely reconfigurable operation and instant-on configuration without external configuration memory.
• Embedded Memory — Total on-chip RAM of 405,504 bits (approximately 0.4 Mbits) combining embedded block and distributed memory resources for buffers, FIFOs and local storage.
• I/O and Interface Flexibility — 188 I/Os with sysIO programmable buffers supporting a broad set of interfaces (LVCMOS 3.3/2.5/1.8/1.5/1.2, LVTTL, SSTL, HSTL, PCI, LVDS, Bus-LVDS, LVPECL, RSDS) to simplify board-level interfacing.
• Memory Controller and DDR Support — Dedicated DDR memory interface capability that can implement DDR up to DDR333 (166 MHz) as provided by the family architecture.
• Clocking — Up to four analog PLLs per device for clock multiplication, division and phase shifting to support complex clocking schemes.
• Reconfiguration & Security — Non-volatile device technology with instant-on behavior, TransFR™ reconfiguration for in-field logic updates, and on-chip configuration without external memory for improved security.
• Low-Power Modes — Sleep mode capability for significant static current reduction (family level specification cites up to 1000× reduction).
• System-Level Tools — IEEE 1149.1 boundary scan and ispTRACY™ internal logic analyzer capability for board debug and test; onboard oscillator options for configuration.
• Power & Temperature — Core voltage supply 1.14 V to 1.26 V; industrial operating temperature range of −40 °C to 100 °C.
• Package & Mounting — 256-ball fpBGA (256-FPBGA, 17 × 17 mm) surface-mount package optimized for compact system designs.

Typical Applications

• Industrial Controls — Implement motor control, protocol bridging and deterministic I/O handling where industrial temperature operation and robust I/O compatibility are required.
• Communications — Use as a flexible interface and protocol-adaptation device with DDR memory support and programmable I/O standards for mid-range network or telecom modules.
• Embedded System Glue Logic — Replace discrete glue logic and reduce BOM by consolidating bus interfacing, buffering and custom logic into a single reconfigurable device.
• In-Field Upgradable Systems — Systems that benefit from field reconfiguration and secure, instant-on operation for remote updates and feature additions.

Unique Advantages

• Non-volatile instant-on capability: Eliminates the need for external configuration memory and enables designs that power up to a known configuration within microseconds.
• In-field reconfiguration (TransFR): Allows updates to device logic while the system remains operational, reducing maintenance windows and enabling feature upgrades.
• Broad I/O protocol support: Programmable sysIO buffers support multiple standards to simplify integration with diverse peripherals and memory subsystems.
• Industrial temperature rating: −40 °C to 100 °C operation supports deployment in temperature-stressed environments without additional thermal qualification notes.
• Compact, production-ready package: 256-FPBGA surface-mount format provides a high I/O count in a 17 × 17 mm footprint for space-constrained boards.
• Integrated system support: On-chip PLLs, boundary scan and internal logic analysis capability reduce external debug hardware and speed system bring-up.
