LFXP20C-4FN256C

The LFXP20C-4FN256C is a non-volatile LatticeXP family FPGA offering 20,000 logic elements and approximately 396 Kbits (405,504 bits) of on-chip RAM in a 256-ball fpBGA (17 × 17 mm) package. Designed for commercial-grade systems, it delivers instant-on operation without external configuration memory and a broad voltage supply range for flexible board-level integration.

Its feature set — including up to 188 I/O pins, programmable I/O standards, multiple PLLs and in-field reconfiguration — makes this device suited for embedded systems, memory interface logic and other applications that require reconfigurable logic with compact package integration and reduced BOM.

Key Features

• Core Logic — 20,000 logic elements provide a sizable fabric for implementing complex combinational and sequential logic.
• On‑chip Memory — Approximately 396 Kbits (405,504 bits) of embedded RAM, delivered as block and distributed memory resources for data buffering and state storage.
• I/O and Package — 188 I/O pins in a 256-ball fpBGA (256-FPBGA, 17 × 17 mm) surface-mount package, suitable for compact board layouts and high-density routing.
• Voltage and Temperature — Flexible supply range from 1.71 V to 3.465 V and a commercial operating temperature range of 0 °C to 85 °C.
• Non‑volatile, Instant‑On Architecture — ispXP non-volatile technology eliminates the need for external configuration memory and enables power-up in microseconds.
• In-field Reconfiguration (TransFR™) — Supports in-system logic updates with the ability to reconfigure SRAM-based logic in milliseconds while the system operates.
• Low‑Power Mode — Sleep mode capability for significant static current reduction (up to 1000× as described in family documentation), useful for power-sensitive designs.
• Clocking — Up to four analog PLLs for clock multiply/divide and phase shifting to support various timing architectures.
• Flexible I/O Standards — Programmable sysIO buffer supports LVCMOS (3.3/2.5/1.8/1.5/1.2 V), LVTTL, SSTL, HSTL, PCI, LVDS, LVPECL and RSDS interfaces as documented for the family.
• Memory Interface Support — Implements interfaces up to DDR333 (166 MHz) for dedicated DDR memory connectivity, per family specifications.
• Compliance — RoHS compliant and supplied in a surface-mount package for standard SMT assembly.

Typical Applications

• Embedded Systems — Implement board-level control, protocol handling and custom logic functions that benefit from instant-on and reconfigurability.
• Memory Interface and Bridging — Use the device’s DDR support and multiple PLLs to implement memory controllers, buffers and timing-critical interfaces.
• High‑Density I/O and Interface Conversion — Leverage 188 I/Os and programmable I/O standards for signal bridging, level translation and mixed signaling on compact PCBs.
• In‑field Upgradable Logic — Apply TransFR reconfiguration to deliver firmware-like updates and feature additions without removing the board from the system.

Unique Advantages

• Non‑volatile, instant-on operation: Eliminates external configuration memory and enables immediate startup in microseconds, simplifying system boot behavior.
• Substantial logic and memory in a small package: 20,000 logic elements and approximately 396 Kbits of embedded memory in a 17 × 17 mm fpBGA reduce board area and BOM complexity.
• Flexible interfacing: Programmable I/O standards and 188 I/Os support a wide range of signaling families for versatile system integration.
• Field reprogrammability: In-field reconfiguration (TFR) and JTAG/system configuration ports allow updates and security without external bitstreams.
• Power management options: Sleep mode provides substantial static current reduction for power-conscious designs.
