EPF8820ATC144-15 Tóm tắt

The Altera EPF8820ATC144-15 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays, providing approximately 8,000 usable gates, 672 logic elements (also called registers), and 112 user I/O pins in a 144-pin TQFP (also referred to as LQFP) package. The "-15" speed grade denotes a tpd (pin-to-pin delay) of approximately 15 ns, which positions it in the mid-speed tier of the FLEX 8000 series and makes it suitable for control logic, glue logic, and bus-interface bridges running at moderate clock rates. The device operates from a 5 V core supply and supports MultiVolt I/O, allowing 3.3 V or 5 V interfacing on the same silicon.

A Field Programmable Gate Array (FPGA) is a semiconductor device whose logic and interconnections are configured by the user via SRAM configuration memory, placing FPGAs in the broader hierarchy of programmable logic devices (PLDs) -> FPGAs -> CMOS programmable logic. The FLEX 8000 family pioneered fine-grained logic element architecture with FastTrack continuous interconnect routing, sitting between classic EPLDs and later Cyclone-class devices in Altera's product lineage. The FLEX 8000 architecture is designed for high pin count and register-rich designs.

Key features of the EPF8820ATC144-15 include in-system reconfigurability via serial or parallel configuration devices (EPC1, EPC1064, EPC1213, EPC1441), JTAG support via the IEEE 1149.1 boundary-scan interface, and MultiVolt I/O for mixed-voltage system integration. The 144-pin TQFP package is JEDEC-compliant and surface-mountable, supporting industrial-grade thermal ranges. The CMOS SRAM technology provides low static power and unlimited re-programmability, in-circuit reconfigurability (ICR) being a hallmark of the FLEX 8000 family.

Architecturally, the EPF8820ATC144-15 implements 672 logic elements arranged into Logic Array Blocks (LABs), each LAB containing eight LEs with a local interconnect. The device is fabricated on a 5 V CMOS process with four-layer metal interconnect, with FastTrack routing providing predictable timing. Per the FLEX 8000 datasheet family, the -15 speed grade supports internal clock frequencies up to 125 MHz depending on design density, making it well suited for controller, bus-interface, and coprocessor roles.

Typical applications include bus-interface bridging (e.g., between 5 V and 3.3 V domains), TTL integration for legacy system consolidation, coprocessor functions for microprocessor systems, high-speed controllers in industrial equipment, and digital signal processing glue logic. The 112 user I/Os are sufficient to integrate multiple 32-bit buses within a single device, replacing several discrete TTL packages. Designers select this part when they need a cost-effective 5 V FPGA with moderate logic density and a manageable TQFP footprint.

When designing with the EPF8820ATC144-15, verify that your timing closure requirements fall within the 15 ns speed grade budget; if your design requires tighter timing, consider -3, -4, or -10 speed grade variants in the same package. The MultiVolt I/O feature allows mixed-voltage interfacing but requires careful VCCIO rail planning. Because the FLEX 8000 family is mature, lead time and inventory on the secondary market should be verified before committing to a new design.

This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers select the right speed grade and package variant for legacy 5 V FPGA designs.
