EPF10K20RC208-4N

Field Programmable Gate Array Overview

The Altera EPF10K20RC208-4N is a Field Programmable Gate Array (FPGA) belonging to the FLEX 10K embedded programmable logic device family. It features 1,152 Logic Elements (LEs) organized into 144 Logic Array Blocks (LABs) and includes three Embedded Array Blocks (EABs) providing a total of 12,288 bits of RAM. The device supports up to 147 user I/O pins and operates within a supply voltage range of 4.75 V to 5.25 V. It is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and is rated for commercial temperature operation from -40°C to +85°C.

Field Programmable Gate Array Feature Summary

• Embedded PLD Architecture: Combines general-purpose logic arrays with dedicated embedded memory blocks (EABs) for System-on-a-Programmable-Chip integration.
• High-Density Logic Resources: Contains 1,152 LEs and 144 LABs, supporting complex state machines, counters, and arithmetic functions via dedicated carry and cascade chains.
• Synchronous Memory Integration: Includes 12,288 bits of embedded RAM configured in EABs, offering self-timed synchronous RAM capabilities without reducing logic capacity.
• MultiVolt I/O Support: Features individual tri-state control, open-drain options, and programmable slew-rate control on I/O pins for flexible interface compatibility.

Field Programmable Gate Array Applications

• Data acquisition systems requiring high-speed ADC control and data buffering in dual-port RAM configurations.
• Industrial control applications utilizing the device's robust logic density and MultiVolt I/O standards.
• Communication equipment implementing protocol conversion and signal processing tasks.
• Video processing systems leveraging the embedded megafunctions for efficient data transformation.

Field Programmable Gate Array Procurement Notes

Verify component authenticity as this part number is from an established legacy series. Confirm that the 208-pin PQFP package matches the target PCB footprint. Ensure power supply design strictly adheres to the 4.75 V to 5.25 V operating range specified for the FLEX 10K family. Check for moisture sensitivity handling requirements during storage and assembly.

Field Programmable Gate Array Selection Notes

Select this device when a balance of moderate logic density (1,152 LEs) and significant embedded memory (12 kbit) is required within a 208-pin QFP package. It is suitable for designs needing 5.0-V tolerant inputs if using compatible variants, though standard 5.0-V operation is primary. Consider the FastTrack Interconnect for predictable routing delays in medium-complexity digital designs.

Field Programmable Gate Array Part Context

The EPF10K20RC208-4N is part of the FLEX 10K family, recognized as the industry’s first embedded programmable logic devices. This series integrates SRAM-based reconfigurable elements with dedicated die areas for specialized functions like memory and DSP. The 'R' suffix indicates the RQFP package type, while 'C' denotes the commercial temperature grade, and '-4' specifies the speed grade.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the end-of-life status of the FLEX 10K series. Designers may need to evaluate modern Intel/Altera FPGA families such as Cyclone or MAX, though these require schematic and layout modifications due to architectural differences and varying pin counts.
