LFXP6C-4TN144I

The LFXP6C-4TN144I is a non-volatile LatticeXP family field programmable gate array (FPGA) offered by Lattice Semiconductor Corporation. It combines approximately 6,000 logic elements with on-chip embedded memory and a flexible I/O fabric to address industrial and embedded applications that require configurable logic, on-board memory, and a wide I/O voltage range.

Key hardware attributes include 73,728 bits of on-chip RAM (approximately 72 Kbits), 100 user I/Os in a 144-pin LQFP package, a broad supply voltage window (1.71 V to 3.465 V) and industrial operating temperature (-40 °C to 100 °C), making it suitable for robust system designs that need instant-on reconfigurability and in-field updates.

Key Features

• Non-volatile, instant-on architecture No external configuration memory is required; the device powers up in microseconds and supports secure configuration without an external bitstream.
• Reconfiguration and in-field updates Infinitely reconfigurable logic with TransFR™ reconfiguration for in-field logic updates and the ability to reprogram SRAM and non-volatile sections via system configuration and JTAG.
• Logic density Approximately 6,000 logic elements suitable for mid-density FPGA implementations.
• Embedded and distributed memory 73,728 total RAM bits (approximately 72 Kbits of embedded SRAM) plus family-level distributed RAM resources.
• Flexible I/O buffer and standards support Programmable sysIO™ buffer supports a wide range of interfaces including LVCMOS (3.3/2.5/1.8/1.5/1.2 V), LVTTL, SSTL, HSTL, PCI, LVDS, Bus-LVDS, LVPECL and RSDS—enabling diverse peripheral and memory interfaces.
• Dedicated DDR memory support Implements interfaces up to DDR333 (166 MHz) for external memory connectivity.
• Clocking and PLLs sysCLOCK PLL resources for clock multiply/divide and phase shifting—LFXP6 devices provide two analog PLLs.
• Low-power modes Sleep mode support provides substantial static current reduction (up to 1000× reduction as specified for the family).
• Package and operating conditions 144-pin LQFP package (supplier device package noted as 144-TQFP, 20 × 20 mm), operating voltage 1.71–3.465 V, and industrial temperature range of −40 °C to 100 °C.
• Compliance RoHS compliant.

Typical Applications

• Industrial control and automation — Configurable logic, industrial temperature rating and flexible I/O allow implementation of motor control, PLC interfaces and custom control logic.
• Embedded systems and appliances — Instant-on, non-volatile configuration and on-chip memory enable compact embedded controllers and user-interface controllers without external configuration storage.
• Memory interface bridging — Dedicated DDR support (up to DDR333) and programmable I/O make the part suitable for memory interface logic and buffering tasks.
• Communications and I/O aggregation — Wide I/O standard support (including LVDS and high-speed signaling options) for protocol bridging, data capture and preprocessing functions.

Unique Advantages

• Instant-on, secure configuration: Non-volatile architecture removes the need for external configuration memory and protects design bitstreams.
• In-field reconfiguration: TransFR and JTAG/system configuration ports enable runtime updates and rapid iterative development.
• Strong I/O flexibility: Broad programmable I/O support reduces the need for additional level-shifting or interface components.
• Compact package with ample I/O: 100 I/Os in a 144-pin LQFP package balances I/O count with a small footprint for space-constrained PCBs.
• Industrial robustness: Wide operating temperature range (−40 °C to 100 °C) and RoHS compliance suit industrial deployments.
• Vendor design ecosystem: Supported by the LatticeISP design flow and pre-designed IP (ispLeverCORE™) to accelerate development.
