EPF8452ATC100-4N Ringkasan

The Altera EPF8452ATC100-4N is a member of the FLEX 8000 family of SRAM-based Field Programmable Gate Arrays, providing 68 user I/Os, 336 logic elements (LEs), and 42 Logic Array Blocks (LABs) in a 100-pin TQFP package. It operates from a 5 V supply and supports in-circuit reconfigurability through CMOS SRAM configuration cells, making it suitable for system-level designs that require rapid prototyping or field updates.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration of a gate array with the design flexibility of in-system programmability. Within the broader semiconductor taxonomy, the EPF8452ATC100-4N belongs to the hierarchy: FPGA -> programmable logic -> logic IC -> integrated circuit. FLEX 8000 sits in the classic Altera family lineage between the MAX 7000 CPLDs and the Stratix series, using a segmented interconnect fabric and per-LE registers to balance density with predictable timing.

Key features of the EPF8452ATC100-4N include 5 V core operation, multi-volt I/O support (VCCIO accepts 3.3 V or 5.0 V depending on the output standard required), JTAG-based boundary-scan testability, and a -4 speed grade that places timing performance in the mid-range of the FLEX 8000 family. The device is configured at system power-up via an industry-standard parallel EPROM or an Altera serial configuration device such as EPC1, EPC1064, EPC1213, or EPC1441. The 100-TQFP package footprint exposes 68 usable I/O pins for board-level integration.

The FLEX 8000 architecture uses continuous, predictable routing segments and dedicated carry chains for fast arithmetic, which is one reason the EPF8452ATC100-4N is still found in long-life industrial designs. Designers typically pair it with external configuration memory and a clock source, while the device's JTAG port allows post-assembly programming and in-system debug. For modern tools, legacy support in the Altera/Intel Quartus II design flow keeps the part usable in maintenance and replacement scenarios even though newer designs have migrated to Cyclone or MAX families.

Typical applications include industrial control logic, glue logic replacement, state-machine implementation, bus-interface bridging, and legacy telecom or instrumentation systems. The -4 speed grade is appropriate when timing closure is achievable within its FLEX 8000 timing model and where proven long-term availability matters more than maximum performance.

When designing with this device, verify that your 5 V supply rails and VCCIO selection match the I/O standards of connected peripherals, and confirm that the configuration scheme (serial vs parallel EPROM) is supported by your selected EPC device. Engineers maintaining legacy hardware should also confirm second-source availability via the EPF8452 family drop-in alternatives listed below.
