Key Features

• Core Logic Approximately 20,000 logic elements with an architecture based on the LatticeXP family.
• Embedded Memory Total on-chip RAM of 405,504 bits (approximately 405.5 Kbits) for distributed and block memory usage.
• I/O Density & Flexibility Up to 188 I/Os in the 256-ball fpBGA package to support multiple interface signals and board routing density.
• Non‑volatile, Instant‑on Configuration ispXP non-volatile technology provides instant-on power-up with no external configuration memory required and options for reconfiguration through system and JTAG ports.
• In-field Reconfiguration TransFR™ reconfiguration enables logic updates while the system is operating, supporting iterative development and field updates.
• Clocking Up to four analog sysCLOCK™ PLLs per device for clock multiplication, division and phase shifting.
• Dedicated Memory Interface Support On-device support for DDR memory interfaces (dedicated DDR memory support described in family data).
• Power and Sleep Modes Core voltage support specified at 1.14 V to 1.26 V and a sleep mode that allows substantial static current reduction.
• Package & Temperature 256-ball fpBGA (17 × 17 mm) supplier device package; commercial operating temperature range of 0 °C to 85 °C.
• RoHS Compliant Meets RoHS environmental requirements.

Typical Applications

• Embedded Systems Acts as a reconfigurable logic backbone for commercial embedded platforms that require high logic density and flexible I/O.
• Memory Interface and Controller Integration Supports designs that implement DDR memory interfaces and require on-chip memory and PLL-based clock management.
• Communications and Interface Bridging High I/O count and programmable I/O buffers make the device suitable for protocol bridging and multi‑standard interface tasks.
• Field‑Upgradeable Products Non-volatile configuration with TransFR reconfiguration enables in-field updates for long-lived commercial products.

Unique Advantages
