LFXP20C-5FN388C

The LFXP20C-5FN388C is a non-volatile FPGA from the LatticeXP family offering 20,000 logic elements, 268 user I/Os and approximately 0.405 Mbits of on-chip RAM. Packaged in a 388-ball fpBGA (23 × 23 mm) and specified for commercial operation (0 °C to 85 °C), it targets cost‑effective system designs that require instant-on behavior, reconfigurable logic and flexible I/O support.

Key Features

• Non-volatile, reconfigurable architecture – Instant-on operation with no external configuration memory required and support for in-system reconfiguration.
• Logic density – 20,000 logic elements suitable for mid-density designs and on-chip implementation of complex logic functions.
• Embedded memory – Total on-chip RAM of 405,504 bits (approximately 0.405 Mbits) combined with distributed RAM resources for data buffering and state storage.
• High I/O count – 268 I/Os to support extensive peripheral and bus connectivity from a single device.
• Flexible I/O and standards support – sysIO programmable buffer options include LVCMOS (3.3/2.5/1.8/1.5/1.2), LVTTL, SSTL, HSTL, PCI, LVDS, Bus‑LVDS, LVPECL and RSDS, enabling a wide range of interface choices.
• Dedicated memory interface – Implements interfaces up to DDR333 for connection to external DDR memory where required.
• Clocking – Up to four analog PLLs for clock multiplication, division and phase shifting to simplify timing architectures.
• Power and sleep – Supply range 1.71 V to 3.465 V with a sleep mode that enables substantial static current reduction for low-power states.
• System-level debug and configuration – IEEE 1149.1 boundary scan and internal trace/logic analysis capabilities, plus an onboard oscillator to support configuration.
• Package and mounting – Surface-mount 388-ball fpBGA (388-FPBGA, 23 × 23 mm) for compact board integration.
• Commercial temperature grade – Rated for 0 °C to 85 °C operation.

Typical Applications

• System control and peripheral interfacing – Use the 268 I/Os and programmable sysIO buffers to manage sensors, displays and multiple bus standards from a single FPGA.
• Memory-interfaced designs – Leverage approximately 0.405 Mbits of embedded RAM and DDR333 interface capability for buffering, packet handling and temporary storage.
• Field-upgradable logic – Instant-on non-volatile configuration and in-field reconfiguration support iterative firmware updates without external configuration memories.
• Prototyping and mid-density integration – 20,000 logic elements and flexible clocking resources make this device suitable for prototyping and integration of mid-complexity digital subsystems.

Unique Advantages

• Instant-on, no external config memory – Eliminates the BOM and board area needed for separate configuration flash while reducing system boot time.
• High I/O capacity – 268 user I/Os enable consolidation of multiple interfaces and reduce the need for external glue logic or multiplexers.
• Integrated memory resources – Approximately 0.405 Mbits of on-chip RAM plus distributed RAM options reduce external memory dependency for many applications.
• Flexible interfacing – Broad sysIO support for common signaling standards simplifies board-level design across multiple subsystems.
• Power management features – Sleep mode capability allows significant static current reduction for low-power product states.
• Compact, surface-mount package – 388-ball fpBGA provides a high-pin-count footprint in a compact 23 × 23 mm package suitable for dense board designs.
