EP20K1000CB652C7N

Overview

The EP20K1000CB652C7N is a high-density programmable logic device from the APEX 20KC family, manufactured by Altera. It utilizes a 0.15-µm all-layer copper-metal fabrication process and operates with an internal supply voltage of 1.8 V. The device features up to 38,400 logic elements (LEs) and supports up to 327,680 RAM bits without reducing available logic resources. It is housed in a 652-pin Ball Grid Array (BGA) package and supports MultiVolt I/O interface voltages of 1.8 V, 2.5 V, and 3.3 V.

Feature Summary

• MultiCore architecture integrating look-up table (LUT) logic and embedded system blocks (ESBs) for memory functions like FIFO, dual-port RAM, and CAM.
• High-performance copper interconnect providing 25% to 35% faster design performance compared to APEX 20KE devices.
• Flexible clock management circuitry featuring up to four phase-locked loops (PLLs), ClockLock, ClockBoost, and ClockShift capabilities.
• Support for advanced I/O standards including LVDS, PCI-X, AGP, CTT, SSTL-3, SSTL-2, GTL+, and HSTL Class I.

Applications

• System-on-a-programmable-chip (SOPC) designs requiring integration of LUT, product-term, and memory-based functions.
• High-speed external memory interfaces supporting DDR SDRAM and ZBT SRAM.
• PCI Local Bus applications compliant with Revision 2.2 for 3.3-V operation at 33 or 66 MHz.
• Complex state machines and register-intensive digital signal processing (DSP) tasks.

Procurement Notes

Verify the specific speed grade suffix '7' against the datasheet Table 1 to confirm it corresponds to the -7 speed grade, which offers the fastest performance within the APEX 20KC series. Ensure the 652-pin BGA package dimensions match the target PCB footprint, as noted in Table 5. Confirm RoHS compliance status if required for the manufacturing environment.

Selection Notes

Select this model when designs require up to 38,400 LEs and significant embedded memory capacity. The -7 speed grade is appropriate for timing-critical applications. Consider the 1.8-V core voltage requirement and ensure compatible level shifters are used for any 5.0-V tolerant I/O interfaces, which require an external resistor. Verify that the 652-pin BGA package is suitable for the assembly process.

Part Context

This component belongs to the APEX 20KC family, which succeeded the APEX 20KE series. It shares pin compatibility with APEX 20KE devices but offers enhanced performance due to the 0.15-µm copper process. The EP20K1000C variant represents the highest density in the base APEX 20KC lineup, offering 38,400 LEs and 160 Embedded System Blocks (ESBs).

Replacement Considerations

APEX 20KE devices are pin-compatible but offer lower performance. Later Intel FPGA families such as Stratix or Arria provide higher densities but require different packaging and software tools. No direct drop-in replacement exists within the same package and pinout for identical functionality without redesign.
