• I/O Density 197 user I/O pins to support multiple interfaces and board-level protocol bridging in a single device.
• Package & Mounting 256-LFBGA (supplier device package: 256-CABGA, 14×14) in a surface-mount package suitable for compact PCB layouts.
• Power Core supply voltage specified from 1.045 V to 1.155 V for predictable power supply planning.
• Thermal & Grade Industrial-grade device rated for operation from −40 °C to 100 °C.
• Architecture & Family Features Built on the ECP5 family architecture which includes programmable I/O cells, clocking resources, sysDSP slices, DDR memory support, and SERDES/physical coding structures as detailed in the ECP5 family datasheet.
• Environmental Compliance RoHS compliant for environmental and regulatory alignment.

Typical Applications

• Programmable logic and glue Implement board-level glue logic and custom control functions using the device’s 12,000 logic elements and abundant I/O.
• I/O bridging and protocol adaptation Use the 197 I/Os to consolidate multiple interfaces and perform protocol translation on a single FPGA.
• On-chip buffering and state Leverage approximately 0.59 Mbits of embedded RAM for small buffering, FIFOs, and state storage without external memory.
• Industrial systems Deploy in industrial-temperature designs that require operation across −40 °C to 100 °C and RoHS compliance.

Unique Advantages
