Key Features

• Logic Capacity  Approximately 19,000 logic elements for implementing mid-range combinational and sequential logic.
• On-chip Memory  Approximately 1.246 Mbits of embedded memory to store buffers, FIFOs and state data directly on the device.
• I/O Density  304 user I/Os to support multiple parallel interfaces, sensor arrays, or mixed-signal front-ends.
• Supply Voltage  Core supply range of 1.14 V to 1.26 V to match system power rails and enable predictable power budgeting.
• Package & Mounting  484-ball FPBGA (23 × 23 mm) package, surface-mount mounting type for compact board integration.
• Industrial Temperature Grade  Specified for operation from −40 °C to 100 °C for deployments in extended-temperature environments.
• Family Capabilities (ECP2/M)  Includes the ECP2/M family feature set from the datasheet such as advanced DSP blocks, flexible memory resources, and high-speed SERDES support (as applicable to ECP2M family devices).
• RoHS Compliant  Conforms to RoHS environmental requirements.

Typical Applications

• Industrial Control  Use for I/O aggregation, protocol bridging, and control logic where extended temperature range and robust I/O count are required.
• Networking & Connectivity  Suitable for mid-range communication endpoints and protocol adaptation leveraging the ECP2M family’s high-speed serial and interface capabilities.
• Embedded Processing Acceleration  Implement hardware accelerators, DSP preprocessing, and custom state machines using available logic elements and embedded RAM.
• Test & Measurement  Ideal for data acquisition front ends and timing-critical sampling logic that benefit from abundant I/O and on-chip memory.

Unique Advantages

• Balanced Logic and Memory: Combines approximately 19,000 logic elements with ~1.246 Mbits of embedded RAM to support mid-sized system functions on a single device.
