LFXP6E-5T144C

The LFXP6E-5T144C is a member of the LatticeXP family of non-volatile FPGAs from Lattice Semiconductor Corporation. This device integrates approximately 6,000 logic elements, about 73 Kbits of on-chip RAM, and 100 user I/Os in a 144‑lead LQFP surface-mount package.

Designed for commercial-grade system designs, the LFXP6E-5T144C provides instant-on non-volatile operation, reconfigurability, on-chip memory and flexible I/O support—making it suitable for embedded control, interface bridging and memory-interface applications that require compact, reprogrammable logic.

Key Features

• Core Logic Approximately 6,000 logic elements provide configurable combinational and sequential logic capacity for glue logic, control and data-path functions.
• On-Chip Memory Approximately 73 Kbits of embedded RAM for distributed and block memory requirements.
• I/O Capacity 100 user I/Os in a 144‑LQFP (20 × 20 mm) package, enabling multiple parallel interfaces and board-level connectivity.
• Non-Volatile, Instant-On Configuration LatticeXP family non-volatile technology provides instant-on operation with no external configuration memory required and the ability to reconfigure SRAM-based logic in milliseconds.
• Reconfiguration and Field Update Support for in-field TransFR™ reconfiguration enables logic updates while the system operates (as documented for the LatticeXP family).
• Clocking Family-level support for analog sysCLOCK™ PLLs; the LFXP6 class includes device PLL resources for clock multiply, divide and phase shifting.
• Flexible I/O Standards Family-level programmable I/O buffers support a wide range of standards (examples documented for LatticeXP: LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS and others), enabling broad interface compatibility.
• Power and Low-Power Modes Sleep mode capability on the LatticeXP family reduces static current for power-sensitive designs.
• Supply and Temperature Core supply specified at 1.14 V to 1.26 V; commercial operating temperature range 0 °C to 85 °C.
• Package and Mounting 144‑lead LQFP (supplier device package 144‑TQFP, 20 × 20 mm), surface-mount, RoHS compliant.

Typical Applications

• Embedded Control Implement control logic and state machines for consumer and commercial systems that benefit from reprogrammable, non-volatile logic.
• Interface Bridging Create protocol adapters and bus bridges using flexible I/O standards and the device’s I/O count for system-level interfacing.
• Memory Interface and Buffering Support dedicated DDR interfaces (family-level DDR333 support is documented for LatticeXP devices) and on-chip SRAM for temporary buffering and data handling.
• System Glue Logic Replace complex discrete logic with a compact FPGA to reduce BOM and simplify PCB routing in compact commercial designs.

Unique Advantages

• Non-volatile instant-on operation: Eliminates the need for external configuration memory and enables immediate startup behavior.
• In-field reconfiguration capability: TransFR™ and reprogrammable SRAM elements allow updates and feature additions without hardware changes.
• High integration in a compact package: 6,000 logic elements, ~73 Kbits RAM and 100 I/Os in a 144‑LQFP package reduce board space and component count.
• Flexible I/O and clocking: Programmable I/O standards and PLL resources support diverse interface and timing requirements for mixed-signal systems.
• Commercial-grade operating range: 0 °C to 85 °C rating and RoHS compliance for standard commercial deployments.
