EPF8820ATC144-12 Tóm tắt

The Altera (Intel) EPF8820ATC144-12 is a member of the FLEX 8000 family of SRAM-based Field-Programmable Gate Arrays, delivering approximately 8,000 usable gates in a 144-pin TQFP (Thin Quad Flat Pack) package. The device integrates 672 logic cells organized into 84 Logic Array Blocks (LABs) and provides 112 user I/O pins, supporting 5.0V core and MultiVolt I/O operation for 3.3V or 5.0V interface compatibility. The -12 speed grade denotes the slowest timing bin in the FLEX 8000 lineup, optimized for cost-sensitive designs where maximum clock frequency is not the primary constraint.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure digital logic functions after manufacture. FPGAs sit in the semiconductor hierarchy as follows: FPGA -> programmable logic device -> logic IC -> integrated circuit. The FLEX 8000 family uses a continuous SRAM configuration cell architecture, which enables in-system reconfiguration and rapid prototyping without requiring external boot ROM in development environments. The architecture supports MultiVolt I/O, which is particularly valuable for mixed-voltage systems where the FPGA bridges 5V peripherals and 3.3V ASICs.

Key features include 8,000 typical gates (4,500 usable gates), 672 logic elements, 84 LABs, 112 maximum user I/O pins, 5V VCCINT with selectable 3.3V/5.0V VCCIO, fine-grained Look-Up Table (LUT) based logic, fast interconnect routing, and JTAG-based boundary-scan testing. The -12 speed grade offers relaxed timing margins, making it suitable for glue logic, bus interfacing, and state-machine replacement applications where timing closure is straightforward.

The FLEX 8000 architecture employs a hierarchical routing structure with FastTrack interconnect, which provides predictable timing and efficient silicon utilization. Configuration data is loaded at system power-up from an industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1213, EPC1064, or EPC1441), or a system controller. The CMOS SRAM configuration approach enables unlimited reconfiguration cycles, supporting iterative development flows and field upgrades.

Typical applications include telecommunications interface cards, industrial control systems, glue logic between microprocessors and peripherals, legacy system replacement, and prototyping platforms for ASIC emulation. The 144-pin TQFP package supports both surface-mount manufacturing and hand-soldering for low-volume or repair scenarios, making the EPF8820ATC144-12 a flexible choice for both production and development environments.

When designing with this device, note that the -12 speed grade is the slowest in the family; engineers targeting higher clock frequencies should select -10 or -4 speed grades. The MultiVolt I/O feature requires explicit VCCIO selection (3.3V or 5.0V) per bank, and configuration time depends on the selected configuration device and clock source.

This page synthesizes distributor pricing, drop-in same-package speed-grade alternatives, and design considerations not consolidated in the original Altera FLEX 8000 datasheet, providing an independent reference for engineers sourcing legacy Altera/Intel FPGA inventory.
