EP20K1000EFI672-2X

Overview

The EP20K1000EFI672-2X is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family, manufactured by Altera. It utilizes the MultiCore architecture, integrating Look-Up Table (LUT) logic, product-term logic, and Embedded System Blocks (ESB). The device features 38,400 Logic Elements (LEs), 160 ESBs, and supports up to 327,680 RAM bits. It operates at a maximum system frequency of 500 MHz with a 1.8 V internal supply voltage (VCCINT). The component is housed in a 672-pin FineLine BGA package with a 1.00 mm pitch, measuring 27 x 27 mm.

Feature Summary

• MultiCore Architecture: Combines LUT-based logic for register-intensive functions, product-term logic for combinatorial paths, and embedded memory.
• High Density: Provides 38,400 LEs, 160 Embedded System Blocks (ESBs), and up to 327,680 RAM bits.
• Clock Management: Includes four Phase-Locked Loops (PLLs), ClockLock for delay reduction, and ClockBoost for multiplication/division.
• I/O Flexibility: Supports MultiVolt I/O interface for 1.8-V, 2.5-V, 3.3-V, and 5.0-V devices.

Applications

• System-on-a-programmable-chip (SOPC) integration
• Complex state machines and control logic
• Digital signal processing (DSP) and arithmetic functions
• Memory implementations including FIFO, dual-port RAM, and CAM

Procurement Notes

Verify the specific ordering suffix 'X' against official manufacturer documentation, as standard datasheets typically list 'EP20K1000E'. Confirm RoHS compliance status, as older APEX 20K variants may not meet current environmental standards. Ensure compatibility with legacy configuration devices like EPC1 or EPC2 for serial programming.

Selection Notes

Select this device for designs requiring high gate density (up to 1.77 million typical gates) and mixed logic types. The 1.8 V core voltage offers lower power consumption compared to 2.5 V variants. Consider the 672-pin FBGA package constraints for board layout and thermal management. Verify that the required I/O standards are supported by the 1.8 V MultiVolt interface.

Part Context

The EP20K1000EFI672-2X is part of the APEX 20KE series, which extends the original APEX 20K family with enhanced features such as additional global clocks and advanced I/O standards. This family was among the first PLDs to integrate SOPC capabilities, combining LUT, product-term, and memory resources on a single die.

Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be sought from the APEX 20K family, such as the EP20K1000EFI672-2. Note that the 'E' suffix denotes the enhanced feature set. Cross-family migration to newer Altera families requires significant architectural redesign.
