This commercial-grade device is designed for applications that require dense, low-voltage programmable logic integration, offering 24,000 logic elements, approximately 1.03 Mbits of on-chip RAM, and 197 usable I/O pins while operating from 1.045 V to 1.155 V and within a 0 °C to 85 °C temperature range.

Key Features

• Core Logic  24,000 logic elements provide ample programmable resources for custom logic, control, and data-path implementations.
• Embedded Memory  Total on-chip RAM of 1,032,192 bits (approximately 1.03 Mbits) for LUT-based buffering, FIFOs, and small data stores.
• I/O Capacity  197 I/O pins to support multiple peripheral interfaces, bus connections, and signal routing within system designs.
• Power and Voltage  Operates from 1.045 V to 1.155 V supply range to match low-voltage system rails and designer power envelopes.
• Package and Mounting  381-FBGA package (supplier device package: 381-CABGA 17 × 17) in a surface-mount format for compact board implementations.
• Commercial Grade Temperature  Rated for operation from 0 °C to 85 °C for standard commercial applications.
• Environmental Compliance  RoHS-compliant manufacturing and materials.
• Family-Level Architecture  As part of the ECP5 family, the device aligns with family features documented in the datasheet, including programmable I/O cells, flexible clocking, DSP-related slices, and SERDES/physical coding sublayer components.

Typical Applications

• Programmable logic and prototyping  Use the 24,000 logic elements and on-chip memory to implement custom logic, control functions, and prototype hardware definitions.
• High-density I/O control  197 I/O pins support complex peripheral interfacing, signal routing, and multi-signal control tasks in compact systems.
• Compact embedded systems  The 381-FBGA surface-mount package and low-voltage operation make this device suitable for space-constrained designs that require programmable logic.

Unique Advantages

• Highly integrated programmable logic: 24,000 logic elements combined with approximately 1.03 Mbits of embedded memory reduces the need for external logic and RAM in many designs.
• Broad I/O capacity: 197 I/O pins enable flexible interfacing to multiple buses, sensors, and peripherals without immediate external multiplexing.
• Compact BGA footprint: 381-FBGA (381-CABGA 17 × 17) provides a dense package option for board space optimization while supporting surface-mount assembly.
• Low-voltage compatibility: Operates within a 1.045 V to 1.155 V supply window to align with modern low-voltage system rails.
• Commercial-temperature suitability: Rated 0 °C to 85 °C for standard commercial deployments.
• Standards-aligned sourcing: RoHS-compliant materials and manufacturing help meet environmental compliance requirements.
