EPM5192LC-45 - MAX 5000 CPLD 192 Macrocells | Altera
MPN： EPM5192LC-45 ✗ 停產EPM5192LC-45 概覽
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs/GALs and large FPGAs in the programmable logic hierarchy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. CPLDs typically offer predictable timing, instant-on behavior, deterministic I/O placement, and lower power consumption than SRAM-based FPGAs, making them ideal for decoder, multiplexer, state-machine, and bus-arbitration roles where deterministic propagation delay matters more than raw gate density.
Key features of the EPM5192LC-45 include 192 macrocells, 48 dedicated input pins, a maximum toggle frequency of 100 MHz, and a 45 ns tPD (pin-to-pin delay) over commercial 0C to +70C operating range. The part uses Altera's classic MAX architecture with a programmable interconnect array (PIA) and supports the company's MAX+PLUS II and older AHDL toolchains. The 'LC' suffix indicates a ceramic-windowed LCC package suitable for prototype and UV-erase development cycles.
The EPM5192LC-45 sits in the hierarchy: programmable logic -> CPLD -> MAX 5000 family -> EPM5192 die. It targets older designs, legacy industrial controllers, and educational applications where the developer needs in-system UV erasure and re-programming, or where the design must remain bit-stream-compatible with vintage AHDL/MAX+PLUS II code bases.
Typical applications include bus interface glue logic, address decoding, state-machine controllers, and legacy industrial automation retrofits. The 'LC-45' speed grade (-45 = 45 ns tPD) places it in the medium-speed tier of the EPM5192 family and is appropriate for asynchronous logic, address decoding, and slow peripheral interfaces.
When designing with this part, note that the EPM5192 family has been discontinued by Intel PSG and is generally only available through obsolete-stock distributors. New designs should target MAX II, MAX V, or MAX 10 CPLD families. The ceramic LCC window package requires a UV eraser for reprogramming.

典型應用
EPM5192LC-45 適用於 6 應用s: Legacy Industrial Control Logic, Address Decoding and Bus Interface Glue Logic, State Machine Controllers, Educational and Prototyping Platforms, Avionics and Defense Legacy Systems, Telecommunications Backplane Glue Logic.
Legacy Industrial Control Logic
The EPM5192LC-45 fits legacy industrial control retrofits where existing designs are coded against the MAX 5000 family and PCB rework is prohibitively expensive. With 192 macrocells the device handles address decoding, I/O expansion, and small state-machine controllers in PLC backplanes and motor-drive interfaces. Its UV-erasable window allows field re-programming during commissioning and fault recovery cycles, and the 45 ns tPD comfortably meets asynchronous bus-arbitration timing. The LCC-68 ceramic package provides the mechanical robustness required for vibration-prone factory environments, and the 5V supply aligns with legacy industrial rails.
推薦
Address Decoding and Bus Interface Glue Logic
The EPM5192LC-45 is well-suited to bus decoding and glue-logic roles in VME, ISA, and custom backplane designs that require predictable, deterministic timing. Its 45 ns tPD provides adequate margin for address-latch, chip-select, and interrupt-controller arbitration, and the 192-macrocell density supports multiple decoder banks in a single device. The deterministic interconnect-array (PIA) architecture of the MAX 5000 family ensures consistent propagation regardless of routing, a key advantage over SRAM-based FPGAs. The 5V I/O is directly compatible with TTL and CMOS logic families used in legacy backplane designs.
推薦
State Machine Controllers
The EPM5192LC-45 supports multi-state Moore and Mealy state machines in instrumentation and process-control equipment where its non-volatile UV-EPROM configuration provides instant-on behavior without external boot memory. The 192 macrocells comfortably encode 16-32 state FSMs with rich output decoding, and the 45 ns tPD yields ~22 MHz state-machine clock rates. Legacy designs using AHDL and MAX+PLUS II can be recompiled and re-targeted to this die without code changes, preserving engineering investment in mature firmware.
推薦
Educational and Prototyping Platforms
The EPM5192LC-45 in ceramic-windowed LCC packaging is ideal for university FPGA/CPLD laboratories where students need to repeatedly erase, re-program, and iterate on designs. The UV window allows hundreds of erase cycles, making it a cost-effective teaching vehicle compared to one-time-programmable plastic parts. The 192 macrocells expose students to realistic design complexity, and the AHDL/MAX+PLUS II toolchain is mature, well-documented, and freely available in legacy archives. The 45 ns tPD is forgiving for student timing budgets.
推薦
Avionics and Defense Legacy Systems
The EPM5192LC-45 supports MIL-spec and avionics legacy systems where long-life-cycle programs require form-fit-function replacement of obsolete Altera MAX 5000 parts. The /883B-screened variants (EPM5192GM/883B, EPM5192JM/883B) provide MIL-STD-883 processing for high-reliability military applications, and the LCC-68 ceramic package meets the hermeticity requirements of military and aerospace electronics. With 192 macrocells it implements redundant voter logic and interface adapters in legacy avionic platforms where modern parts are not yet qualified.
推薦
Telecommunications Backplane Glue Logic
The EPM5192LC-45 fits telecom backplane designs requiring fast, deterministic bus arbitration, address decoding, and interrupt steering. The MAX 5000 family's instant-on non-volatile behavior eliminates the boot delays of SRAM FPGAs, enabling rapid system start-up required in central-office equipment. With 192 macrocells and 45 ns tPD, it comfortably handles multi-master bus arbiters and clock-distribution networks. The 5V I/O is compatible with legacy telecom ASIC environments where 3.3V parts cannot be used.

主要差異化特點
- Slowest speed grade available in the EPM5192 family (對比EPM5192LC-35)
- Commercial temperature range vs industrial -1 variant (對比EPM5192LC-1)
- UV-erasable ceramic-windowed package (對比EPM5192JC-1 (plastic J-lead))
設計說明
The EPM5192LC-45 has been discontinued by Intel PSG (formerly Altera). New production runs are not feasible. When designing a replacement, do NOT assume a modern MAX II/MAX V CPLD is drop-in compatible - they use different packages, JTAG programming, and 3.3V cores requiring PCB rework. For legacy support, plan for at least 4-12 week obsolete-component lead times and verify the part date code to avoid counterfeit risk.
Estimated: at 5V supply with all 192 macrocells switching at 10 MHz, the EPM5192LC-45 draws approximately 200-300 mA. The LCC-68 ceramic package has theta_JA of approximately 30-40 C/W (estimated), so a fully loaded part can dissipate 1-1.5W, yielding a 30-50C junction temperature rise above ambient. Ensure the LCC socket provides adequate thermal dissipation or consider a heatsink for high-utilization designs.
The LCC-68 ceramic package requires a through-hole socket (e.g., 3M Textool or equivalent) for UV-erase development cycles. For production, the plastic J-lead (JC) variant is recommended. Decoupling: place 0.1 uF ceramic capacitors on every VCC/GND pair within 5 mm of the package leads, and add a 10 uF tantalum bulk capacitor on each supply rail. The MAX 5000 family is sensitive to supply noise - inadequate decoupling can corrupt configuration memory.
The 45 ns tPD is a best-case pin-to-pin delay; actual timing depends on the number of macrocell stages, fan-out, and interconnect routing. Use Altera MAX+PLUS II timing analysis to verify worst-case delays. For designs exceeding ~10 MHz internal clock rates, choose a faster speed grade (-35 or -25) to maintain timing margin. Output drive strength is fixed at TTL-compatible 24 mA - no slew-rate control is available on MAX 5000 devices.
