EP20K1000CF33C8N

Overview

The Altera EP20K1000CF33C8N is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KC family. It utilizes a 0.15-µm all-layer copper-metal fabrication process and operates at an internal supply voltage of 1.8 V. The device provides up to 38,400 logic elements (LEs), 160 Embedded System Blocks (ESBs), and supports up to 327,680 RAM bits. It features MultiCore architecture integrating look-up table (LUT) logic and embedded memory. The component is housed in a FineLine BGA package with 672 pins and supports I/O standards including LVDS, PCI-X, and SSTL.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term-based logic for complex state machines.
• Embedded System Blocks (ESBs) supporting FIFO buffers, dual-port RAM, content-addressable memory (CAM), and ROM.
• Flexible clock management with up to four phase-locked loops (PLLs), ClockLock, ClockBoost, and ClockShift features.
• Support for high-speed interfaces including 3.3-V PCI Local Bus (33/66 MHz), LVDS, and MultiVolt I/O (1.8-V, 2.5-V, 3.3-V).

Applications

• Complex digital signal processing (DSP) designs requiring optimized data-path performance.
• System-on-a-programmable-chip (SOPC) implementations integrating logic, memory, and interface controllers.
• High-density applications requiring fast arithmetic functions via dedicated carry and cascade chains.

Procurement Notes

Verify the specific ordering suffix CF33C8N against official documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as historical records may vary. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCNs) prior to procurement. Ensure design tools support the legacy APEX 20KC architecture.

Selection Notes

Select this device for designs requiring up to 38,400 LEs and significant embedded memory resources within a single chip. Consider the -8 speed grade for timing requirements between -7 and -9 grades. Verify that the 672-pin FineLine BGA package fits the board space constraints. Ensure the design utilizes the 1.8-V core voltage while managing appropriate VCCIO levels for external interfaces.

Part Context

The EP20K1000C is part of the APEX 20KC series, which offers 25% to 35% faster performance than the preceding APEX 20KE devices. It is pin-compatible with APEX 20KE devices in corresponding packages. The series was manufactured using a 0.15-µm copper interconnect process to enhance performance and reduce power consumption compared to previous generations.

Replacement Considerations

APEX 20KE devices are pin-compatible but offer lower performance. Modern replacements include Stratix or Agilex families, though these require significant redesign due to architectural differences and lack of pin compatibility.
