A MAX 5000 EPLD is a one-time or UV-erasable programmable logic device from the early-1990s CMOS PLD era that combines the density of multiple PAL/GAL devices into a single non-volatile package. The hierarchy is: macrocell -> logic array block (LAB) -> Programmable Interconnect Array (PIA) -> EPLD -> programmable logic -> semiconductor IC. This family replaces 7400-series TTL/CMOS SSI/MSI packages, freeing board area and reducing system power.
Key features include 16 macrocells, 160 product terms, 8 dedicated output macrocells with individually programmable I/O polarity, and a single global clock network for synchronous state-machine design. The EPM5016LC-17 is specified at the 17 ns tPD speed grade (commercial temperature range), making it suited for control-path glue logic, address decoding, and bus-interface state machines that do not require the 20 ns or 15 ns grades.
The architecture uses a CMOS EEPROM-based logic element with a PIA providing predictable, fixed-delay interconnect — unlike SRAM-based FPGAs, interconnect delay is deterministic and timing closure is straightforward. This makes the part well suited to legacy 5V-tolerant logic consolidation designs, vintage industrial controller upgrades, and form-fit-function replacements for original MAX 5000 designs.
Typical applications include 16-bit address decoding for microprocessor/microcontroller glue logic, peripheral-chip select generation, vintage ISA bus interface logic, industrial PLC drop-in logic replacement, and educational CPLD/EPLD lab platforms. The non-volatile configuration is retained without external memory.
When designing with the EPM5016LC-17, plan for a 5V VCC supply, observe the LC package's pinout against the original Altera datasheet, and verify that the 17 ns tPD is acceptable for the target clock domain. New designs should consider the modern MAX II or MAX V families, but for legacy support this part remains a faithful drop-in.

典型應用
EPM5016LC-17 適用於 6 應用s: 16-bit Address Decoding / Glue Logic, Vintage ISA / Peripheral Bus Interface, Industrial PLC Drop-In Logic Replacement, Educational CPLD/EPLD Lab Platform, Form-Fit-Function Legacy Avionics Replacement, Telecom Backplane Chip-Select Decoder.
16-bit Address Decoding / Glue Logic
The EPM5016LC-17 is well suited to 16-bit microprocessor address decoding and glue-logic consolidation in legacy systems. Its 16 macrocells with 160 product terms easily fit full 64K-address or 1M-address decoder maps with multiple chip-select outputs. The 17 ns tPD matches the timing budgets of vintage 8 MHz and 12 MHz 8086/80186 designs, where address-decode propagation must complete within half a clock cycle. The Programmable Interconnect Array provides deterministic, fixed interconnect delay so timing closure is straightforward — unlike SRAM FPGAs where routing delay varies with placement. For modern designs this function is replaced by a MAX II or MAX V CPLD, but for legacy support the EPM5016LC-17 remains a faithful one-chip replacement for four to six 74LS138/139/151 decoder packages.
推薦
Vintage ISA / Peripheral Bus Interface
The EPM5016LC-17 provides a single-chip bus-interface state machine for ISA, STD, or proprietary peripheral buses. The 8 bidirectional I/O lines plus 7 dedicated inputs map cleanly onto an 8-bit data bus with control signals such as IOR, IOW, chip-select, and address-enable. The single global clock input supports synchronous bus-cycle generation. With 16 macrocells the part can implement both the address decode and the handshake/READY state machine, replacing 4-6 discrete PAL/GAL devices. The 17 ns tPD is compatible with the 8 MHz ISA bus standard timing, and the non-volatile EEPROM configuration means no external boot PROM is needed — a key advantage over SRAM-based FPGA solutions of the era.

Industrial PLC Drop-In Logic Replacement
Industrial PLC and process-control systems from the early 1990s were built around MAX 5000 EPLDs for compact relay-logic and ladder-logic replacement. The EPM5016LC-17's 16 macrocells and 8 outputs can replace the discrete 7400-series SSI/MSI logic implementing input conditioning, output multiplexing, and fault-latching in a single package. The windowed ceramic DIP (LC) package is preferred for field-reprogramming during commissioning, since UV erase allows iterative design updates. The 17 ns tPD accommodates the millisecond-class scan times of PLC backplanes, leaving substantial timing margin. For hazardous-environment retrofits, this part is often the only form-fit-function equivalent that fits existing PCB footprints without mechanical rework.
推薦
Educational CPLD/EPLD Lab Platform
The EPM5016LC-17 is a classic teaching platform for university digital-logic labs because the windowed ceramic DIP package allows students to UV-erase and reprogram the device multiple times across lab sessions. Its 16 macrocells, 8 outputs, and 7 dedicated inputs give students enough resources to implement decoders, counters, and small state machines without overwhelming the curriculum. The 17 ns tPD is slow enough that students can observe signal propagation on a logic analyzer and verify timing diagrams against theory. The Altera MAX+PLUS II legacy design toolchain (still available in academic archives) accepts schematics and AHDL/Verilog entry. This makes the EPM5016LC-17 a preferred part for digital-design courses covering combinational and sequential logic synthesis.

Form-Fit-Function Legacy Avionics Replacement
Avionics LRUs (line-replaceable units) certified in the 1990s often used MAX 5000 EPLDs as part of their DO-160-qualified designs. Re-certification of an LRU is prohibitively expensive, so legacy support demands form-fit-function equivalents that drop into the original socket without PCB changes. The EPM5016LC-17 in its windowed ceramic DIP package preserves the original mechanical envelope and pinout, allowing avionics shops to rebuild spares without re-certifying the LRU. The 17 ns tPD is sufficient for ARINC 429 bus-interface and discrete I/O conditioning. The EEPROM-based non-volatile configuration means no separate boot PROM and no in-system programming infrastructure is required at the LRU level — preserving the original maintenance concept.
推薦
Telecom Backplane Chip-Select Decoder
Telecom backplanes from the early 1990s used MAX 5000 EPLDs as multi-drop chip-select decoders for shared-bus architectures such as VMEbus and Multibus. The EPM5016LC-17's 8 outputs are sufficient to decode 6-8 slave boards with individual interrupt-request arbitration. The single global clock input can synchronize board-grant signals, while the 7 dedicated inputs accept address lines and bus-control strobes. The 17 ns tPD fits VMEbus DTB cycles at 8-12 MHz with margin for backplane propagation. The deterministic PIA interconnect delay is critical because backplane timing must be guaranteed worst-case, which SRAM FPGAs cannot provide without over-conservative design margins.

主要差異化特點
- Windowed ceramic package enables iterative UV-erase development (對比EPM5016DC-17)
- 17 ns tPD is the typical speed grade for vintage 8-12 MHz designs (對比EPM5016LC-15)
- EPM5016LC-17 is the medium-speed bin within the EPM5016 family (對比EPM5016LC-20)
設計說明
The EPM5016LC-17 operates from a 5V VCC supply typical of the MAX 5000 family. Estimated: total quiescent current at room temperature and 1 MHz operation is approximately 50-100 mA for a fully-utilized 16-macrocell design. Add a 0.1 uF ceramic decoupling capacitor close to the VCC pin and a 10 uF bulk capacitor on the supply rail. Legacy 5V systems often share supply with TTL logic, so verify that the local regulator can source the combined ICC plus I/O switching current.
Do not assume the EPM5016LC-17 is in-system programmable — it requires a separate Altera programming hardware (e.g., PL-MPU or equivalent) and either a UV eraser for LC packages or pre-programmed parts for DC OTP packages. Designers migrating from SRAM FPGAs are often surprised that MAX 5000 devices do not support JTAG/ISP. Plan programming and erase steps explicitly in the production workflow, and order pre-programmed parts from distributors for volume builds.
Place decoupling capacitors within 5 mm of the VCC pin and use a ground plane to minimize supply noise. The MAX 5000 family uses TTL-compatible I/O with relatively slow edge rates (~5 ns), so controlled-impedance routing is not as critical as for modern FPGAs, but keep clock and high-speed I/O traces short. The windowed ceramic DIP package requires a socket or careful handling to avoid scratching the UV-transparent quartz window — finger oils and scratches prevent UV erase.
Estimated: with 17 ns tPD and typical 5V TTL outputs, the I/O edge rate is approximately 3-5 ns. For designs above 12 MHz clock rate, treat each output as a transmission line and use series termination (33-68 ohm) at the source if the trace exceeds 50 mm or crosses a connector. The 8 I/O pins share a common output-enable architecture; if any pin is configured as a high-speed output, isolate it from slower inputs to avoid ground-bounce coupling.
合規資訊
Compliance data not available in verified web sources. The MAX 5000 family predates modern RoHS compliance requirements; LC ceramic DIP packages typically contain lead-bearing solder and are not RoHS compliant. DC plastic DIP variants may be available in RoHS-compliant builds depending on date code.
