EPF8282ALC84-4 Ringkasan

The Altera EPF8282ALC84-4 is a member of the FLEX 8000 family of SRAM-based CMOS Field Programmable Gate Arrays (FPGAs) housed in an 84-pin PLCC (Plastic Leaded Chip Carrier, J-Lead) package. The device integrates 208 logic elements arranged in 26 Logic Array Blocks (LABs) and provides 68 user I/O pins for high-density, register-rich programmable logic designs. It is supplied from a nominal 5V rail (4.75V-5.25V) and operates over the commercial 0C to +70C temperature range. The -4 speed grade reflects the slowest of the FLEX 8000 family grades, providing the longest propagation delay but at the lowest cost.

An FPGA (Field-Programmable Gate Array) is a programmable logic device belonging to the broader PLD (Programmable Logic Device) family, which itself falls under digital ICs and semiconductors. FPGAs sit hierarchically above simple PLDs and below ASICs, offering higher logic density than CPLDs while preserving field programmability. The FLEX 8000 series combines the high register count and fine-grained interconnect of an FPGA with features normally associated with mask-programmed gate arrays, including in-circuit reconfigurability (ICR) via SRAM configuration cells.

Key features include 2,500 usable gates, 208 logic elements, 26 LABs, and 68 user I/Os. The FLEX 8000 architecture uses CMOS SRAM configuration elements that are 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. MultiVolt I/O allows the device to interface with mixed-voltage systems supporting 3.3V or 5.0V I/O pin operation across the family.

Typical applications include glue logic replacement, bus interface bridging, state-machine and controller implementation, peripheral emulation in legacy industrial systems, and prototyping of larger ASIC designs. The 5V tolerance and PLCC footprint make it well-suited to long-lifecycle industrial and telecom designs where through-hole or socketed assembly is preferred over fine-pitch QFP.

Designers should note that the SRAM-based configuration is volatile: the device must be reconfigured at every power-up. PCB layouts must respect the PLCC-84 socket's mechanical constraints and provide a robust configuration source. As a -4 speed-grade part, propagation delay is the longest in the family - consult the FLEX 8000 datasheet for timing margins in time-critical paths.
