EPM5192LC-2 - 192-Macrocell MAX 5000 CPLD, 45ns, PQCC84 | Altera
MPN: EPM5192LC-2 ✗ Cuối đờiEPM5192LC-2 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on characteristics of PAL/GAL architecture with the density of an FPGA, organized as an array of Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA). The MAX 5000 family was Altera's third-generation EPLD/CPLD line, predating the later MAX 7000/MAX II families and widely deployed in legacy telecom, industrial-control, and military systems. Within the broader taxonomy, a CPLD falls under programmable logic devices (PLD) -> logic ICs -> integrated circuits.
Key features of the EPM5192LC-2 include 192 macrocells arranged in 12 Logic Array Blocks, 7 dedicated input pins, and one external clock input. The architecture uses a shared input/clock scheme, with each macrocell containing a programmable AND/OR array and a configurable flip-flop. The -2 speed grade denotes the slower of the two production speed bins for this die, trading off tPD against lower dynamic power consumption versus the -1 grade. The PQCC84 JEDEC-standard package (also known as PLCC-84) is a surface-mount J-lead plastic carrier rated for the standard Altera commercial temperature range.
The EPM5192LC-2 is typically used in legacy bus-interface designs, address decoding, peripheral control logic, and glue logic between microprocessors and peripherals. It is also commonly deployed in industrial automation backplanes, telecom line cards, and military/aerospace subsystems where its non-volatile MAX architecture and long-life-cycle pedigree remain advantageous. Compared to modern SRAM-based FPGAs, it offers instant-on configuration (no external boot PROM required) and very predictable timing, which simplifies static timing closure.
Designers should note that the EPM5192 family is a legacy part with limited active distributor stock; sourcing typically goes through brokers, franchised distributors carrying residual inventory, or the authorized Altera/Intel FPGA channel for the Long-Term Supply program. A pin-compatible modern alternative within the Altera (now Intel) portfolio is the MAX 7000A series in the same PLCC-84 footprint, while cross-brand options exist from Lattice (ispMACH 4000 family) and Xilinx (XC9500XL family) — see the alternatives section for full details.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes drawn from the legacy Altera MAX 5000 datasheet — context that is not aggregated on any single distributor product page and is intended to accelerate sourcing decisions for engineers maintaining EOL systems.

Ứng dụng tiêu biểu
EPM5192LC-2 phù hợp cho 6 Áp dụngs: Legacy Telecom Line-Card Glue Logic, Industrial Control Backplane Address Decoding, Military/Aerospace Avionics Subsystem Logic, Legacy Microprocessor Peripheral Interfacing, Test & Measurement Instrument Custom Logic, Automotive Aftermarket ECU Replacement Logic.
Legacy Telecom Line-Card Glue Logic
The EPM5192LC-2 is well-suited to legacy telecom line-card glue logic where its 192 macrocells, 64 user I/Os, and 50 MHz internal frequency provide ample capacity for TDM bus steering, address decoding, and protocol conversion between T1/E1 framers and the host CPU. Its non-volatile EPROM-based configuration means the card powers up in a known valid state — critical for telecom infrastructure that must come online deterministically after a power interruption. The 45 ns tPD comfortably meets setup/hold margins for 8.192 MHz TDM buses and most legacy memory-mapped peripheral interfaces. Designers should note that sourcing this part today requires broker channels; pairing with the Lattice ispMACH 4000 as a second-source is recommended for new designs, but for maintaining installed EOL telecom fleets the EPM5192LC-2 (or its -1 speed-grade variant) remains the lowest-risk replacement.

Industrial Control Backplane Address Decoding
The EPM5192LC-2 delivers reliable, instant-on address-decoding and bus-control logic for VME/PCI/ISA industrial backplanes where deterministic power-up behavior is mandatory. With 192 macrocells and 12 LABs, designers can implement multi-master arbiter state machines, chip-select generators, and interrupt controllers in a single device, replacing 4-6 discrete PAL/GAL chips. The 45 ns propagation delay supports ISA-bus timing (8 MHz with comfortable margin) and most VMEbus DTB cycles. Its CMOS process and 5 V supply make it tolerant of the industrial input-voltage ranges commonly found on legacy backplanes. For new designs, pair it with the EPM5192LC-1 to gain headroom; for retrofitting existing boards, the EPM5192LC-2 remains functionally identical to its original installation and survives reflow profiles compatible with SnPb and lead-free processes when handled per the original Altera packaging specifications.

Military/Aerospace Avionics Subsystem Logic
The EPM5192LC-2 (and its military-processed variants such as EPM5192GM-2 and EPM5192JM-2/883B) has historically been qualified into avionics subsystems, missile guidance test fixtures, and naval electronics where its non-volatile, radiation-tolerant EPROM-based CPLD architecture offers deterministic instant-on behavior without needing SRAM-configuration scrubbing. The 192-macrocell capacity suits medium-complexity state machines such as MIL-STD-1553 bus controllers, ARINC 429 interface glue, and radar timing generators. When sourcing for military programs today, the EPM5192GM-2 (883B-processed) is the preferred drop-in, while the -2 commercial part is acceptable for ground-test fixtures and development boards. Designers must verify current DSCC/VMER sourcing status with the franchised distributor; lead times for military-processed variants typically extend 12-26 weeks.

Legacy Microprocessor Peripheral Interfacing
The EPM5192LC-2 is widely deployed as the interface bridge between legacy microprocessors (Motorola 68000, Intel 8086/80186, Zilog Z80) and peripheral chips lacking modern bus protocols. With 64 user I/O pins and 7 dedicated inputs, the device can implement wait-state generators, bus-transceiver direction controls, DMA acknowledge steering, and interrupt priority encoders in a single chip. The 45 ns tPD comfortably satisfies 68000 bus timing at up to 12 MHz and 80186 timing at up to 8 MHz with full margin. The PQCC-84 (PLCC-84) socketable package simplifies field replacement on legacy boards. For modern designs, the same role can be served by a MAX 7000AE in the same footprint, but for maintaining installed 68000/80186/Z80 systems the EPM5192LC-2 (or its -1 speed-grade variant) remains the lowest-risk replacement with proven long-term reliability data.

Test & Measurement Instrument Custom Logic
The EPM5192LC-2 is well-suited to custom trigger, sequencing, and front-panel logic inside bench-top test instruments where non-volatile, instant-on behavior is desired over an SRAM-based FPGA. Its 50 MHz internal frequency and 45 ns tPD comfortably generate precision timing sequences, IEEE-488 handshake state machines, and front-panel switch-debounce/encoding logic. The PQCC-84 socketed package simplifies rework during prototype iterations. When designing a new instrument, the Lattice ispMACH 4000 family offers a modern cross-brand alternative but typically in TQFP/QFP packages requiring PCB rework; the EPM5192LC-2 is the recommended drop-in when maintaining an existing instrument design where the PCB footprint is fixed.
Được đề xuất
Automotive Aftermarket ECU Replacement Logic
While the EPM5192LC-2 is not AEC-Q100 qualified (Altera never offered this part with automotive PPAP), it has been widely used in aftermarket and grey-market automotive ECU repair shops to replace failed OEM glue-logic CPLDs from the 1990s and early 2000s. With 192 macrocells and 64 I/Os, it can replicate the address decoding, sensor conditioning, and actuator drive timing found in legacy ECUs. Its 5 V supply and commercial temperature range are adequate for under-hood retrofit when paired with proper thermal management. For new automotive designs, AEC-Q100-qualified MAX 7000AE or Lattice ispMACH 4000ZE variants are required; the EPM5192LC-2 should only be used to maintain existing ECU repairs where the OEM CPLD was originally this part. Designers should verify the operating-temperature envelope against the target vehicle's under-hood temperature profile before deployment.

Bảo phân biệt quan trọng
- Faster propagation delay than the -2 grade at identical footprint (vsEPM5192LC-1)
- Same die, ceramic package for prototyping and military/extended temperature (vsEPM5192GC-2)
- Industrial temperature grade at the same footprint (vsEPM5192JC-2)
Ghi chú thiết kế
The EPM5192LC-2 operates from a single +5 V supply; decouple VCC pins (22, 44, 70) with 0.1 µF ceramic capacitors placed within 5 mm of each VCC pin, plus a single 10 µF tantalum or aluminum polymer bulk capacitor near the package. The MAX 5000 family is sensitive to supply noise during programming — a clean +5 V rail is required for reliable in-system programming via the JTAG port. Estimated: ICC during continuous operation is typically 150-300 mA depending on switching activity; verify with the actual design's toggle rate.
For the PQCC-84 (PLCC-84) socketed design, use a machined-pin socket (e.g., 3M Textool or equivalent) with retention clips to ensure reliable contact through thermal cycling. The J-lead footprint requires a PCB land pattern per JEDEC MO-047; pad dimensions are typically 0.040 x 0.060 inch (1.0 x 1.5 mm) with 0.050 inch (1.27 mm) pitch. Place all decoupling capacitors on the same PCB side as the CPLD to minimize loop inductance; via-to-inner-plane stitching should surround the device at 1 mm pitch for EMI suppression.
Do not assume any modern Altera/Intel Quartus toolchain supports the MAX 5000 family — design entry requires the legacy MAX+PLUS II or MAX+PLUS II Baseline tool, which only runs on Windows and is no longer actively maintained. Plan for tool obsolescence when designing new code for this part; archive design files with the BitBlaster or ByteBlaster programming configuration. Also note: the EPM5192 is one-time-programmable (OTP) in its plastic package variant — once programmed, the design cannot be erased; use the ceramic windowed package (EPM5192GC) for prototyping.
Thông tin tuân thủ
MAX 5000 family predates RoHS; PQCC-84 plastic J-lead package uses tin-lead (SnPb) finish. Not AEC-Q100 qualified — automotive designs should use MAX 7000AE or modern ispMACH equivalents. Reach and conflict-mineral status not published by Altera for this legacy part.
