LFXP20C-4F256C

The LFXP20C-4F256C is a non-volatile FPGA from Lattice Semiconductor’s LatticeXP family, delivered in a 256-ball fpBGA (17 × 17 mm) surface-mount package. It integrates 2,464 logic blocks (20,000 logic elements), approximately 405,504 bits of on-chip RAM, and 188 I/Os to support reconfigurable system logic with dense I/O and embedded memory.

This device is designed for applications that require instant-on configuration, flexible I/O standards, and in-field reconfigurability while operating over a commercial temperature range and a wide supply range.

Key Features

• Core / Logic  2,464 logic blocks and 20,000 logic elements provide capacity for mid-range FPGA designs and complex glue logic integration.
• Embedded Memory  Approximately 405,504 bits of on-chip RAM (embedded block and distributed memory) for buffering, FIFOs and local data storage.
• I/O and Package  188 programmable I/Os in a 256-FPBGA (17 × 17 mm) package; surface-mount mounting for compact board integration.
• Non-volatile Configuration  ispXP non-volatile technology enables instant-on power-up without external configuration memory and provides design security.
• Reconfiguration and Power Modes  TransFR™ in-field reconfiguration for updating logic while the system operates, plus a Sleep Mode that enables up to 1000× static current reduction.
• Clocking and Memory Interfaces  Up to four analog PLLs for clock multiply/divide and phase shifting; dedicated DDR memory support up to DDR333 (166 MHz).
• Flexible sysIO™ Buffers  Programmable I/O buffer support for a wide range of signaling standards as defined by the family architecture.
• Supply and Temperature  Supply range: 1.71 V to 3.465 V. Operating temperature: 0 °C to 85 °C. Commercial grade and RoHS compliant.
• System Level Support  IEEE 1149.1 boundary-scan (JTAG), ispTRACY internal logic analyzer capability, and on-board oscillator support for configuration.

Typical Applications

• Embedded systems  Instant-on non-volatile configuration and on-chip memory are well suited for embedded control, signal preprocessing, and system glue logic.
• Memory interface and buffering  Built-in DDR support and on-chip RAM enable interface logic, memory buffering and local data staging for systems using external DRAM.
• Multi-protocol I/O and protocol bridging  Programmable sysIO buffers and 188 I/Os support mixed signaling standards for communications, interface conversion and protocol aggregation.
• In-field upgradeable designs  TransFR reconfiguration allows updates to FPGA logic while the system remains operational, useful for deployed systems needing feature updates.

Unique Advantages

• Instant-on, non-volatile operation: Eliminates the need for external configuration memory and enables rapid power-up without external boot steps.
• In-field reconfigurability: TransFR™ reconfiguration enables logic updates during operation, reducing maintenance downtime and enabling field feature upgrades.
• Integrated memory reduces BOM: Approximately 405,504 bits of on-chip RAM minimize external memory requirements for many buffering and processing tasks.
• Flexible I/O and clocking: Extensive sysIO programmability and up to four PLLs let designers adapt signaling and timing to diverse system needs.
• Compact, high-density package: 256-FPBGA with 188 I/Os provides a small-footprint solution for space-constrained boards requiring significant I/O.
• Power management features: Sleep Mode with large static current reduction helps reduce power draw in standby or low-activity conditions.
