EP1810GI-45 Présentation
A UV-erasable PLD (also called an EPLD or erasable programmable logic device) is a non-volatile logic IC that can be configured by the user to implement custom combinational and sequential logic. PLDs sit within the broader programmable logic hierarchy that includes PROMs, PALs, GALs, CPLDs, and FPGAs; the Classic EPLD family represents one of the earliest erasable, macrocell-based PLD architectures. Programming is performed electrically via a dedicated programmer, and erasure is achieved by exposing the die through the quartz window to ultraviolet light, after which the device can be reprogrammed - making EP1810GI-45 well suited to prototype and low-volume production environments.
Key features include 24 dedicated macrocells, 48 flip-flops, 45 ns propagation delay (tpd), and CMOS technology for low power operation. The CPGA-68 ceramic package with UV window supports field reprogramming, while the 45 ns speed grade enables use in glue-logic, bus interfacing, state-machine control, and address decoding roles in legacy systems. The device is offered in -45 (45 ns) and -35 (35 ns) speed grades within the same Classic EPLD architecture.
In a typical application, the EP1810GI-45 implements glue logic between microprocessors and peripherals, replacing multiple discrete 74-series logic ICs with a single programmable device. The CMOS process keeps quiescent power low, while the ceramic PGA package and integrated UV window make it straightforward to erase and reprogram during development. The 45 ns propagation delay is sufficient for asynchronous bus decoding, register-decode multiplexing, and glue logic in systems running at MHz-class clock rates.
Typical applications include legacy industrial control logic, replacement of discontinued 74-series discrete logic, address decoding, state-machine controllers, I/O expansion for older microprocessors, and military/aerospace systems where the ceramic package and known Altera Classic EPLD silicon are required. The UV-erasable window also makes it suitable for secure prototyping where bitstream erasure between builds is mandatory.
When designing with EP1810GI-45, ensure the programmer socket supports the 68-pin CPGA pinout and the device is erased with the correct UV dose prior to reprogramming. The ceramic CPGA package is through-hole and not RoHS-equivalent; for new designs consider modern surface-mount CPLDs in QFP or BGA packages with similar macrocell counts. Stock is supported by Rochester Electronics as an authorized Altera Classic EPLD franchise partner.

Applications typiques
EP1810GI-45 convient pour 6 applications: Legacy Industrial Control Logic, Microprocessor Bus Address Decode, Glue Logic Replacement for Discrete 74-Series ICs, State Machine Controllers, I/O Expansion and Bus Multiplexing, Military and Aerospace Legacy Avionics.
Legacy Industrial Control Logic
The EP1810GI-45's 24 macrocells and 45 ns propagation delay make it well suited for legacy industrial control boards where it replaces several discrete 74LS/74HC logic ICs implementing motor-control state machines and sensor-conditioning glue. The CMOS process keeps quiescent current low, and the ceramic CPGA package tolerates the wide temperature and vibration environment of factory floors. Field engineers appreciate the UV-erasable window for last-minute logic revisions without re-spinning the PCB, an important consideration for long-life industrial equipment. The Rochester Electronics franchise supply chain continues to support these legacy control designs through their authorized Altera Classic EPLD silicon stockpile.
Recommandé
Microprocessor Bus Address Decode
The EP1810GI-45's 24 macrocells and 48 flip-flops are sufficient for full 24-bit address-decode logic for microprocessors such as the 8086, 68000, or Z80 in legacy embedded systems. The 45 ns tpd aligns with the address-to-chip-select timing window of these microprocessors, ensuring that peripheral enables remain glitch-free even at the rated bus-clock frequencies. CMOS technology reduces the Icc draw of address-decode PLDs versus bipolar PAL counterparts, helping legacy boards meet thermal budgets. The UV window also permits rapid design iteration during board bring-up, where decode maps change frequently during firmware development.
Recommandé
Glue Logic Replacement for Discrete 74-Series ICs
A single EP1810GI-45 can functionally replace an entire board section of discrete 74LS244, 74LS245, 74LS138, 74LS151, and 74LS374 chips, freeing PCB area and reducing the bill-of-materials count on legacy logic boards. The 24 macrocells comfortably accommodate 8 to 12 small SSI/MSI functions, while the 45 ns tpd preserves the original timing budgets of 74LS-grade designs. CMOS technology reduces the quiescent current draw by approximately 80% versus the bipolar 74LS families it replaces, an attractive feature for legacy systems on tight thermal budgets. The ceramic PGA package is footprint-compatible with the original 68-pin through-hole discrete logic layouts.
Recommandé
State Machine Controllers
With 48 flip-flops and 24 macrocells, the EP1810GI-45 is well suited for implementing Moore and Mealy state machines with up to several dozen states for sequencer, controller, and protocol-handshake applications. The 45 ns tpd provides comfortable timing margin for asynchronous state transitions and edge-detect sequencing in legacy industrial and aerospace sequencers. The UV-erasable window enables engineering teams to iterate on state-machine designs during prototype validation without re-spun programmers. Rochester Electronics' authorized silicon ensures long-term availability for aerospace sequencer designs that may be in service for decades.
Recommandé
I/O Expansion and Bus Multiplexing
The EP1810GI-45's macrocell-rich architecture makes it ideal for I/O expansion, bus multiplexing, and signal routing in legacy microcomputer systems where multiple peripheral buses share a common processor bus. Its 45 ns tpd handles bus-turnaround timing comfortably for MHz-class microprocessor systems, while the CMOS process keeps power dissipation low in continuously-active I/O-mux roles. The CPGA-68 ceramic package is footprint-compatible with older discrete-logic I/O-mux boards, enabling drop-in modernization. Rochester Electronics' franchise distribution keeps these parts in stock for long-lifecycle industrial I/O systems.
Recommandé
Military and Aerospace Legacy Avionics
The ceramic CPGA-68 package, military temperature screening, and known Altera Classic EPLD silicon make the EP1810GI-45 a long-standing choice for military and aerospace avionics, ground-support equipment, and defense electronics where a UV-erasable PLD with deterministic timing is preferred over reprogrammable flash-based logic. Its 45 ns tpd aligns with the conservative timing margins typical of avionics designs, and Rochester Electronics' military-screened variants (e.g., EP1810GM-45) extend the operating temperature range. The long-life cycle of military platforms - often 20 to 30 years - is supported by Rochester's authorized Classic EPLD franchise stocking program, which guarantees continued silicon availability for legacy defense designs.

Notes de conception
Estimated: The EP1810GI-45 must be erased with a UV dose of approximately 30 W·s/cm^2 (watt-seconds per square centimeter) of 254 nm UV light before reprogramming. Insufficient erasure time leaves residual programming charges that cause functional errors and unreliable operation. Use a dedicated UV eraser, not sunlight or fluorescent room light, and confirm erasure by a blank-check read on the programmer before reprogramming.
Estimated: The CPGA-68 ceramic package has a typical theta_JA of approximately 30 C/W in still air. At CMOS EPLD quiescent and dynamic currents, total package dissipation at 5 MHz internal logic toggling remains well below 1 W, so the junction-to-ambient rise is roughly 30 C above ambient - acceptable for commercial temperature operation. For military temperature screening (-55C to +125C), use the EP1810GM-45 or EP1810GM-35 variants that share the same CPGA-68 pinout.
The CPGA-68 package is through-hole and not RoHS compliant; the lead finish is typically SnPb. For lead-free reflow compatibility, choose modern surface-mount CPLDs in the Altera MAX II / MAX V family (for example EPM240T100C5N or 5M80ZT100C5N from the Site MPN list) in TQFP-100 packages. When replacing EP1810GI-45 on a legacy through-hole board, use a PGA-to-PGA adapter or migrate to a daughter-board design.
The EP1810GI-45 requires a dedicated Altera Classic EPLD programmer (e.g., Data I/O or BP Microsystems programmers with EPLD Classic support modules) and a CPGA-68 programming socket. Modern Altera/Intel USB-Blaster programmers do not support the Classic EPLD family - verify programmer compatibility before committing to the EP1810GI-45 in prototype development. JEDEC fuse-map files (.jed) written for EP1810GI-45 are forward-compatible with EP1810GC-35 and EP1810GM-45 in the same package.
Informations de conformité
Ceramic CPGA-68 package is through-hole SnPb, RoHS non-compliant by exemption may apply for military/aerospace. Reach compliant per Rochester Electronics part listing. Not AEC-Q100 qualified; military temperature variants (EP1810GM-45) follow MIL-STD-883 screening rather than automotive AEC-Q100.
