LFXP3C-4TN144C

The LFXP3C-4TN144C from Lattice Semiconductor is a non-volatile XP family FPGA in a 144-pin LQFP/TQFP package. It provides 3,000 logic elements, approximately 55,296 bits of on-chip RAM and up to 100 I/Os, making it suitable for compact, commercial embedded designs that require reprogrammable logic with flexible I/O and on-chip memory.

Built on the ispXP™ non-volatile architecture, this device supports instant-on behavior, in-field reconfiguration and multiple I/O standards while operating across a broad supply range and commmercial temperature grade.

Key Features

• Core Capacity — 3,000 logic elements (cells) and 384 PFU/PFF resources provide deterministic logic capacity for moderate-density designs.
• Embedded Memory — Approximately 55,296 bits of total on-chip RAM for distributed and block memory use, enabling buffering, small FIFOs and local data storage without external RAM.
• I/O and Package — 100 user I/Os in a 144-LQFP / 144-TQFP (20 × 20 mm) surface-mount package, offering a compact footprint for space-constrained boards.
• Voltage Range — Flexible supply operation from 1.71 V to 3.465 V to support mixed-voltage systems and a variety of I/O standards.
• Non-volatile, Instant-on Configuration — ispXP™ non-volatile architecture with instant-on capability and no external configuration memory required.
• Reconfiguration and Security — Supports JTAG and system configuration ports for programming and in-field updates; reprogrammable non-volatile storage secures configuration data.
• Low-Power Modes — Sleep mode available for significant static current reduction.
• Clocking — Device-level PLLs for clock multiply/divide and phase adjustment (LFXP3 family devices include 2 PLLs).
• Flexible I/O Standards — sysIO buffer supports LVCMOS (3.3/2.5/1.8/1.5/1.2 V), LVTTL and a range of high-speed and memory interfaces as documented in the LatticeXP family data.
• Operating Range & Mounting — Commercial grade operation from 0 °C to 85 °C; surface-mount package for standard PCB assembly.
• RoHS Compliant — Device meets RoHS environmental requirements.

Typical Applications

• Commercial Embedded Systems — On-board programmable logic for protocol translation, glue logic and custom control functions where compact package and on-chip RAM are required.
• Interface Bridging — Flexible I/O and multiple supported voltage levels enable bridging between different bus and peripheral standards in space-constrained implementations.
• Prototyping and Development — Instant-on, reprogrammability and JTAG support make the device suitable for design validation and iterative development cycles.

Unique Advantages

• Instant-on non-volatile FPGA: Eliminates the need for external configuration memory and provides fast power-up for designs that require immediate logic availability.
• Balanced integration: Combines 3,000 logic elements with ~55 Kbits of on-chip RAM and 100 I/Os in a single compact 144-pin package to reduce BOM and board area.
• Flexible power and I/O: Wide supply range (1.71 V–3.465 V) and broad sysIO support let you interface multiple voltage domains without extra level-shifting ICs.
• Field reconfiguration: In-system and JTAG programming with TransFR™ reconfiguration capability enable updates and in-field logic changes.
• Low-power options: Sleep mode support provides a path to significantly reduce static current when the application is idle.
• Commercial temperature rating: Rated for 0 °C to 85 °C operation, matching many consumer and commercial application environments.
