LFXP2-8E-5TN144C

The LFXP2-8E-5TN144C is a commercial-grade LatticeXP2 family FPGA in a 144-pin LQFP package. It combines a LUT-based FPGA fabric with on-chip non-volatile flash architecture to provide instant-on, reconfigurable logic for embedded digital designs. Typical use cases include control, interface bridging, signal processing, and display or memory interface functions where moderate logic density, embedded RAM, and flexible I/O are required.

Key Features

• Core Logic — Approximately 8,000 logic elements supporting designs that require mid-range LUT capacity.
• Embedded Memory — Approximately 226,304 bits of on-chip RAM to support data buffering, state storage and small SRAM-based functions.
• Configurable I/O — Up to 100 user I/Os with flexible buffer standards for a wide range of digital interfaces; surface-mount package simplifies board integration.
• Flash-based Architecture (flexiFLASH) — Instant-on, infinitely reconfigurable single-chip flash architecture with on-chip FlashBAK memory and serial tag support for design security and non-volatile configuration.
• Live Update and Security — Family-level Live Update capabilities with secure update mechanisms including 128-bit AES encryption and dual-boot support (as documented for LatticeXP2 family).
• sysDSP and Multipliers — Family support for dedicated DSP resources and hardware multipliers to accelerate multiply-accumulate workloads (as provided by the LatticeXP2 family).
• Clocking — On-chip PLL resources for clock multiply/divide and phase shifting to meet system timing requirements.
• Power and Operating Range — Operates from a 1.14 V to 1.26 V supply with an ambient operating temperature range of 0 °C to 85 °C (commercial grade).
• Package and Mounting — 144-LQFP package (supplier device package listed as 144-TQFP, 20 × 20 mm) designed for surface-mount assembly.
• RoHS Compliant — Manufactured in compliance with RoHS environmental requirements.

Typical Applications

• Embedded Control and Glue Logic — Implement custom control state machines, bus bridging and peripheral interfacing using available logic elements and I/Os.
• Signal Processing — Leverage family DSP resources and on-chip multipliers for moderate-performance filtering, aggregation or data manipulation tasks.
• Memory and Display Interfaces — Use the flexible I/O and pre-engineered source-synchronous interfaces documented for the LatticeXP2 family to implement DDR/DDR2 or multi-lane LVDS links.
• Prototyping and Reconfigurable Systems — Flash-based configuration enables instant-on prototypes and field-reconfigurable products with secure update capability.

Unique Advantages

• Instant-on non-volatile configuration: Flash-based flexiFLASH architecture removes the need for external configuration memory for immediate startup.
• Secure and maintainable firmware: Live Update and AES-based secure update mechanisms reduce risk when deploying field firmware updates.
• Balanced integration: Mid-range logic capacity, substantial on-chip RAM and dedicated DSP resources provide a compact solution that reduces external component count.
• Flexible I/O and clocking: Comprehensive I/O buffer options and on-chip PLLs allow adaptation to diverse interface and timing requirements without additional chips.
• Commercial-grade operating envelope: Designed for 0 °C to 85 °C environments with a defined supply voltage window for predictable system behavior.
