LFXP3E-4T144I

The LFXP3E-4T144I is an industrial-grade FPGA from Lattice's LatticeXP family, built on non-volatile ispXP technology. This surface-mount 144-pin TQFP/LQFP device integrates approximately 3,000 logic elements, about 54 Kbits of embedded RAM, and 100 user I/Os in a compact 20 × 20 mm package, delivering instant-on, reconfigurable logic for embedded and industrial systems.

Designed for applications that require robust operation across -40 °C to 100 °C and a core supply range of 1.14–1.26 V, the device combines on-chip memory, flexible I/O, low-power modes and in-field reconfiguration capabilities to simplify system design and accelerate time to market.

Key Features

• Non-volatile ispXP architecture  Instant-on operation with no external configuration memory required and built-in protection against bit-stream read-back.
• Core capacity  Approximately 3,000 logic elements organized across 384 logic blocks for compact logic implementation.
• Embedded memory  Approximately 55,296 bits (~54 Kbits) of on-chip RAM for distributed and block storage needs.
• Flexible I/O  100 user I/Os on the 144-LQFP package to support a variety of system interfaces and peripheral connections.
• Programmable I/O buffer and interface support (family)  Family-level sysIO buffer options support a wide range of standards including multiple LVCMOS levels, LVTTL, SSTL, HSTL, PCI, LVDS and others.
• On-chip clocking  Integrated PLL resources (LFXP3 devices provide 2 PLLs) for clock multiply/divide and phase-shifting requirements.
• Low-power operation  Sleep mode capability for significant static current reduction during idle or low-power states.
• Reconfiguration and in-field update  TransFR™ reconfiguration enables in-field logic updates while the system remains operational; supported configuration and JTAG access for programmability.
• Package and mounting  Surface-mount 144-LQFP / 144-TQFP (20 × 20 mm) package suitable for compact PCB designs.
• Industrial temperature range  Rated for operation from -40 °C to 100 °C for deployment in industrial environments.

Typical Applications

• Industrial control and automation  Instant-on and industrial temperature range make the device suitable for control logic, protocol bridging and machine interface tasks.
• Embedded system glue logic  Compact logic capacity and flexible I/O enable integration of custom interfaces and timing control between subsystems.
• Communications and protocol adaptation  Programmable I/O buffer options and on-chip PLLs facilitate implementation of protocol conversion and timing-critical interfaces.
• Sensor aggregation and preprocessing  On-chip memory and reconfigurable logic allow local data buffering, preprocessing and aggregation of multiple sensor streams.

Unique Advantages

• Instant-on, non-volatile operation  Eliminates external configuration memory and enables fast system start-up without additional components.
• Compact, integrated solution  Combines logic, embedded RAM and I/Os in a single 144-pin package to reduce board area and BOM complexity.
