EPF8452ALC84-4 Ringkasan

The Intel / Altera EPF8452ALC84-4 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs) housed in an 84-pin Plastic Leaded Chip Carrier (PLCC, J-Lead) package. It integrates approximately 4,000 usable gates, 336 logic elements (LEs), and 68 user I/O pins, fabricated on a 0.42 micrometer CMOS process and operating from a single 5V supply. The device supports in-circuit reconfigurability (ICR), allowing the logic and interconnect to be re-programmed in-system without removing the part from the board.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high gate density of gate-array ASICs with the design flexibility of user-programmable logic. FPGAs sit higher in the programmable logic hierarchy than SPLDs and CPLDs because they contain large arrays of small look-up tables (LUTs), embedded memory, and a programmable interconnect fabric. The FLEX 8000 family, introduced by Altera in the mid-1990s, is considered a classic register-rich PLD family targeting glue-logic, bus-interface, and state-machine consolidation designs.

Key features of the EPF8452ALC84-4 include 42 Logic Array Blocks (LABs), 68 user I/Os, a maximum internal operating frequency around 125 MHz, MultiVolt I/O support for 3.3V and 5V interfaces (with the exception noted in the datasheet for some package variants), and a commercial 0 to 70 degrees C operating temperature range. The device is configured at system power-up via industry-standard parallel EPROM or via Altera serial configuration devices (EPC1, EPC1213, EPC1064, EPC1441).

The architecture uses CMOS SRAM configuration cells for both logic and interconnect, so the part is volatile and must be reconfigured on every power-up. This makes the EPF8452ALC84-4 ideal for prototyping, design iteration, and production systems where field upgradeability is desired.

Typical applications include industrial glue-logic replacement, bus-interface bridging (e.g., between legacy 5V microcontrollers and 3.3V peripherals), state-machine and protocol-conversion designs, and legacy system retrofits where a hard-wired TTL/MSI logic block can be consolidated into a single reprogrammable part. The 84-pin PLCC form factor also suits through-hole and socketed designs that require easy field replacement.

When designing with the EPF8452ALC84-4, ensure the configuration memory source (parallel EPROM or EPCx serial device) is correctly wired to the dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DATA, DCLK). Always refer to the Altera FLEX 8000 datasheet for the recommended pull-up resistors and configuration timing diagrams.
