The device integrates 531,200 logic elements, 28,033,024 bits of embedded memory, 21248 LABs/CLBs, 920 user I/Os, and embedded transceivers for high-speed serial connectivity, making it one of the largest members of the Stratix IV GX family. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device that combines configurable logic blocks, programmable interconnect, programmable I/O, and on-chip memory into a single semiconductor. Within the system hierarchy, FPGAs sit between Application-Specific ICs (ASICs) and general-purpose processors, offering ASIC-like performance and parallelism with the re-programmability of software. Stratix IV GX devices extend this model with multi-gigabit transceivers, hard PCIe and memory controller IP blocks, and DSP blocks, so the EP4SGX530NF45C4N is used wherever designers need ASIC-class throughput without paying NRE costs. Key features of the EP4SGX530NF45C4N include 531,200 logic elements (the highest density option in the Stratix IV GX family), 28 Mb of embedded SRAM, 24 transceivers supporting data rates up to 8.5 Gbps, 920 user I/Os in 24 banks, 1,024 18x18 multipliers for DSP, an 0.9 V core voltage, and hard PCI Express Gen1/Gen2 IP blocks. The -C4 speed grade targets the highest performance corner; the N suffix denotes a lead-free, RoHS-compliant package. Architecturally, the device uses Altera's adaptive logic module (ALM) which combines 8-input fracturable LUTs with two adders, allowing designs to map to either fine-grained logic or arithmetic-heavy structures. Combined with the hard transceiver PCS/PMA blocks and the TriMatrix memory architecture (MLAB, M9K, M144K blocks), the EP4SGX530NF45C4N supports >1500 GMACS of fixed-point DSP performance at typical operating conditions. Typical applications include high-end telecommunications line cards (100G/40G OTN, packet processing), ASIC prototyping and emulation, high-performance computing fabrics, military/aerospace signal processing, broadcast video processing, medical imaging systems, and test and measurement equipment. Designers choose this density for system-on-chip emulation or when integrating an entire line-card datapath into a single FPGA. When designing with the EP4SGX530NF45C4N, careful PCB layout is essential: the FC-FBGA-1932 substrate requires microvia stack-up design, length-matched differential pairs for transceivers, and substantial decoupling (typically 100 nF + 10 µF per VCC/GND pair). The 0.9 V core is sensitive to IR drop; use at least four PCB layers dedicated to power/ground. Designers should plan for Quartus II (legacy) or Quartus Prime design software and a 12-16 week lead time given the part is now NRND.

The hard PCIe Gen2 IP block and 8.5 Gbps transceivers make this family a frequent choice for line cards requiring both packet processing and high-speed serial I/O. When designing with the EP4SGX70DF29I3G, pay close attention to PCB BGA breakout: the 780-ball FCBGA package typically uses 1.0 mm ball pitch and demands a multilayer stack-up with microvia or HDI technology. Power-rail sequencing must follow the Stratix IV Power Management Guide to avoid latch-up; the 0.9 V core rail should ramp before or simultaneously with the 1.1 V transceiver analog rail, and never exceed the absolute maximum values stated in the datasheet.

The Intel (formerly Altera) EP610DC-10 is a 16-macrocell Classic EPLD from the original Altera Classic device family, fabricated on advanced CMOS technology and packaged in a 24-pin ceramic DIP (CDIP). It delivers pipelined data rates up to 100 MHz with a 10 ns pin-to-pin propagation delay (-10 speed grade), making it one of the earliest high-density programmable logic devices for glue-logic and state-machine integration. What is an EPLD? An EPLD (Erasable Programmable Logic Device) is a type of programmable logic IC that sits between simple PAL/GAL devices and modern CPLDs/FPGAs in the PLD hierarchy: PLD -> EPLD -> CPLD -> FPGA -> programmable logic -> semiconductor. EPLDs use non-volatile EEPROM or EPROM storage to retain configuration at power-off, and provide predictable combinational and registered logic with deterministic timing - ideal for replacing multiple SSI/MSI discrete logic gates in a single package. Key features of the EP610DC-10 include 16 macrocells, 24 I/O pins in the CDIP-24 windowed-ceramic package, 100 MHz pipelined throughput, and a propagation delay of 10 ns at the commercial temperature range. The Classic architecture provides a programmable AND/OR array feeding 16 output macrocells, each containing a programmable flip-flop for synchronous logic. EPROM-based configuration allows unlimited reprogramming when the device is erased under UV light through the quartz window on the top of the ceramic package. The EP610DC-10's 24-pin ceramic DIP is windowed (erasable) and uses through-hole mounting, suitable for prototype, lab, and legacy industrial systems. The 'DC' suffix indicates the CDIP-24 ceramic DIP package, while '-10' denotes the 10 ns speed grade. The device requires a single 5V supply and supports TTL-compatible I/O. Applications include legacy industrial control, address decoding, state machines, and bus-interface glue logic in older computer and telecom designs.

A Classic EPLD (Erasable Programmable Logic Device) is the predecessor to modern CPLDs (Complex Programmable Logic Devices). It is a non-volatile, reprogrammable logic IC that combines the simplicity of PAL architecture with the density of multiple PAL-like macrocell arrays on a single die. The Classic EPLD sits within the broader taxonomy: programmable logic -> PLD -> EPLD -> CMOS EPLD -> Classic EPLD family. Compared to modern CPLDs, Classic EPLDs offer lower density but retain useful advantages: deterministic timing, simple JEDEC fuse-map programming, and 5V tolerant I/O. The device features 20 dedicated inputs and 16 bidirectional I/O pins, organized as four Logic Expanders with 160 total product terms, supporting sum-of-products Boolean implementation through a fixed AND/OR/three-state structure. The EP610DC-15 operates from a single 5 V supply (4.75 V to 5.25 V) and offers a typical quiescent current around 50 mA, with commercial 0C to 70C operating range as denoted by the DC package code. Architecture-wise, the EP610 uses Altera's Classic AND-OR architecture with each macrocell providing a programmable D/T/J-K flip-flop, four product terms for logic, and one output enable product term. Programming is performed using a standard JEDEC fuse map via Altera's programming hardware; the UV window in the ceramic DIP enables erasure by exposure to ultraviolet light, hence the name UV PLD. Typical applications include bus decoding and address mapping in 8086/68K microprocessor systems, state-machine replacement for SSI/MSI logic, I/O decoding and wait-state generation, and TTL-to-CMOS logic consolidation. It is also used in legacy industrial controllers, test equipment, and prototyping where modern CPLDs are not required. When designing with the EP610DC-15, ensure the programming algorithm and JEDEC file are compatible with the 610 macrocell architecture. The CDIP-24 ceramic package has a transparent quartz window for UV erasure; protect the window from ambient light with opaque labels after programming to prevent data corruption.

In the modern taxonomy, PLDs sit under the broader umbrella of programmable logic devices -> EPLD -> Classic UV-PLD -> semiconductor. They are positioned above simple PALs (smaller arrays, no registered outputs) and below modern CPLDs and FPGAs (larger logic capacity, in-system programmability, SRAM or flash-based configuration). Key features of the EP610DC-20 include 16 macrocells with selectable D/T/JK flip-flops, a single 5 V supply, a pin-compatible speed-grade family with 20/15/10 ns tPD options (EP610DC-20/DC-15/DC-10), 160 product terms (also called 'p-terms'), and a dedicated clock/clear architecture. Each macrocell drives one of the 16 bidirectional I/O pins, and 4 pins are dedicated inputs only, giving a usable logic capacity of approximately 24 pins total. The device is supported by the legacy Altera MAX+PLUS II development environment (and MAX II), which compiles AHDL, VHDL, or schematic designs into the JEDEC fuse-map for programming. The architecture is a classic AND-OR-NOT PLA feeding a configurable output macrocell. Each macrocell has a programmable output polarity, a tri-state buffer, and an optional flip-flop (D, T, JK, or latch). Product-term allocation is fixed (no expander chain), which simplifies timing analysis: all signals reach the OR array with a single tPD delay. This deterministic timing is one of the main reasons EPLDs were used in place of discrete TTL or early FPGAs in the 1980s and 1990s for glue logic, address decoding, and state machines. Typical applications include legacy bus-interface glue logic (e.g., address decoding for ISA, VME, or STD-bus cards), state-machine controllers for industrial equipment, register and counter arrays replacing multiple 74LS/74F packages, and pin-compatible retrofits for systems that were originally designed around the EP610 family. The 24-pin CDIP-24 ceramic package makes it especially suitable for military, aerospace, and high-reliability programs where a UV-clearable hermetic device is preferred over plastic UV-windowless plastic PLDs. When designing with this part, note that the configuration is volatile until programmed and that the ceramic DIP provides a quartz window for UV erasure. Programming requires an Altera-compatible parallel programmer (e.g., LogiCade, BP Microsystems) since modern USB programmers do not target this legacy family. Decoupling requires 0.1 µF ceramic capacitors on every VCC pin, plus a bulk tantalum or electrolytic cap on the board-level 5 V rail.

EP610DC-25 - 16-Macrocell Classic EPLD, 25ns tPD, CDIP-24 | Rochester
The Rochester Electronics EP610DC-25 is a high-performance 16-macrocell Classic EPLD from the Altera Classic EPLD family, originally manufactured by Altera (now Intel PSG) and presently authorized for continued production and distribution by Rochester Electronics as a long-life-cycle partner. Per the EP610 datasheet family specification, the EP610DC-25 integrates 300 gates, 16 macrocells, and 22 I/O pins in a 24-pin ceramic DIP (CDIP-24) through-hole package, with a worst-case pin-to-pin propagation delay (tPD) of 25 ns and pipelined data rates reaching up to 100 MHz. A Classic EPLD (Erasable Programmable Logic Device) is a type of early-generation programmable logic IC that combines the high integration of a PLD with the erasable, reprogrammable nature of UV-erasable CMOS logic. EPLDs sit within the broader programmable logic hierarchy: PLD -> CPLD (Complex PLD) / EPLD -> FPGA. The Classic family targets glue-logic, decode, and state-machine applications where a small number of logic equations must be implemented with deterministic, TTL-equivalent timing. Key specifications include a maximum tPD of 25 ns, 22 user I/O pins, 4 dedicated input pins (24 pins total minus VCC/GND), 16 macrocells, 300 equivalent gates, an internal supply voltage of 4.75 V to 5.25 V (5 V nominal), and a commercial operating temperature range of 0 C to +70 C. The -DC- suffix indicates the ceramic DIP package, while the -25 speed grade indicates the 25 ns tPD timing bin. Architecturally, the EP610 uses a sum-of-products AND/OR array feeding 16 output macrocells with programmable output polarity and feedback paths, allowing combinatorial and registered logic to be implemented in a single device. The CMOS EPROM technology gives the part zero standby current when not being read, while the macrocell flip-flops provide synchronous register-based state-machine support. With pipelined data rates to 100 MHz, the EP610DC-25 is suitable for high-speed decoder, address-decode, and bus-arbitration roles in legacy 5 V systems. Typical applications include bus decode and address decoding in 5 V microprocessor systems, glue logic in industrial controllers, state-machine controllers for instrumentation, and pin-compatible logic replacement for legacy designs where the original Altera Classic EPLD must be renewed. The 24-pin DIP form factor is also favored for breadboarding and educational platforms. When designing with the EP610DC-25, ensure the design is implemented in legacy Altera Classic EPLD design tools or compatible JEDEC fuse-map programming software, as modern Quartus software does not support the Classic family.
EP610DC-30 - Classic EPLD, 16 Macrocells, 30ns | Altera
The Altera EP610DC-30 is a Classic EPLD (Erasable Programmable Logic Device) featuring 16 macrocells and 300 usable gates, packaged in a 24-pin ceramic DIP (CERDIP) form factor with a 30 ns propagation delay grade. As a member of the EP610 family, this device implements high-performance CMOS EPROM-based programmable logic with pipelined data rates of up to 100 MHz, targeting legacy glue-logic and state-machine replacement tasks in industrial, telecommunications, and aerospace systems. A Classic EPLD is an early-generation programmable logic device that uses EPROM cells to store the configuration. In the broader taxonomy, the EP610DC-30 sits inside the PLD (Programmable Logic Device) family, which is a subset of programmable logic alongside CPLDs and FPGAs. EPLDs were widely adopted in the late 1980s and 1990s as a means of replacing discrete 74-series TTL/MSI glue logic, integrating state machines, address decoders, bus arbiters, and counter/timer functions into a single non-volatile, one-time-programmable (windowed-erasable UV) IC. The Classic device family preceded the MAX series and offers pin-to-pin compatibility across the EP610 and EP910 lines. Key features include 16 macrocells organized in 4 Logic Expanders, 16 dedicated input pins, and 16 I/O pins with output enable control, plus a programmable clock with global and per-macrocell options. The EP610DC-30 supports a maximum toggle frequency of 100 MHz in pipelined mode, delivers a tPD (pin-to-pin propagation delay) of 30 ns in commercial temperature grade, and offers both registered and combinatorial output modes. The device also features a synchronous preset and asynchronous clear network, plus a security bit to protect proprietary designs after programming. Architecturally, the EP610DC-30 uses a sum-of-products (AND-OR-XOR) PLA-like structure with a global interconnect that routes the 16 inputs and 16 feedback paths into 4 Logic Expanders, each producing 4 product terms per macrocell. The JEDEC-standard 24-pin ceramic DIP package supports through-hole mounting, which is typical for legacy and aerospace applications where socketed, field-replaceable logic remains preferred. Typical applications include TTL/MSI glue-logic replacement in industrial controllers, address decoding in 8-bit and 16-bit microprocessor systems (such as 8086 and 68000 bus interfaces), state-machine implementations in telecom and instrumentation, and aerospace/avionics systems requiring ceramic-package reliability. Designers transitioning from 74LS/74ALS logic to a programmable equivalent often select this part for its predictable timing and EPROM non-volatility. When designing with the EP610DC-30, note that ceramic DIP packages require through-hole PCB footprints and are not compatible with modern surface-mount assembly processes. Programming requires a UV-erasable window (no in-system programmability), and design entry uses legacy tools such as Altera MAX+PLUS II or the older A+PLUS environment. Designers should verify second-source availability (Rochester Electronics and Intel/Altera continue to manufacture this part) before committing to new designs.
