LFXP20E-3FN388C

The LFXP20E-3FN388C is a LatticeXP family FPGA delivering a non-volatile, instant-on programmable fabric with extensive on-chip memory and flexible I/O. Featuring 20,000 logic elements and approximately 0.406 Mbits of embedded RAM, this surface-mount 388-ball BGA device is suited for system designs that require reconfigurable logic with secure configuration and fast start-up.

Its combination of high I/O count (268), dedicated clocking resources, and support for in-field reconfiguration targets embedded applications and system-level designs that need on-chip memory, sophisticated I/O, and fast configuration behavior.

Key Features

• Core Logic — 20,000 logic elements provide a programmable fabric for implementing complex digital functions and custom logic.
• Embedded Memory — Total on-chip RAM of 405,504 bits (approximately 0.406 Mbits) for distributed and block memory requirements.
• I/O Capacity — 268 I/Os available in the 388-ball fpBGA (23 × 23 mm) package to support dense peripheral and bus interfaces.
• Non-volatile, Instant-on Architecture — Family-level features include non-volatile configuration with no external configuration memory required, enabling rapid power-up.
• Reconfiguration and In-field Updates — TransFR™ reconfiguration allows in-field logic updates while the system operates; JTAG and system configuration ports are supported for reprogramming.
• Low-Power Modes — Sleep mode capability enables large static current reductions (up to 1000× as specified for the family).
• Clocking — Up to four analog/sysCLOCK PLLs for clock multiply/divide and phase shifting.
• Voltage and Mounting — Core supply operating range from 1.14 V to 1.26 V; surface-mount package (388-FPBGA, 23×23 mm).
• Operating Range & Grade — Commercial grade device rated for 0 °C to 85 °C operation.
• Compliance — RoHS compliant.

Typical Applications

• Embedded Systems — Implement control logic, protocol bridges or custom processing functions using the device’s on-chip memory and 20,000 logic elements.
• High-density I/O Interfaces — Use the 268 I/Os in the 388-BBGA package for parallel interfaces, bus arbitration, or multi-channel signal routing.
• Memory Interface and Timing — Dedicated PLLs and family-level DDR support enable integration with external memory interfaces and timing-sensitive designs.
• Field-upgradable Systems — TransFR reconfiguration and JTAG support allow in-field updates and iterative feature deployment without removing the device from the system.

Unique Advantages

• Instant-on Non-volatile Operation: Eliminates the need for external configuration memory and enables rapid power-up behavior for systems that require immediate availability.
• High Logic and Memory Integration: 20,000 logic elements combined with approximately 0.406 Mbits of on-chip RAM reduce external component needs and simplify board-level design.
• Flexible I/O Density: 268 programmable I/Os in a compact 23 × 23 mm fpBGA package provide room for complex peripheral and bus connectivity.
• In-field Reconfiguration: TransFR capability supports live updates to logic while the system remains operational, improving maintainability and upgrade paths.
• Power Management Features: Sleep mode support (family-level) offers substantial static current reduction for power-sensitive designs.
• Commercial Temperature and RoHS Compliance: Designed for commercial applications with a 0 °C to 85 °C operating window and RoHS compliance for regulatory alignment.
