EPM5192LC-M148A - Altera MAX 5000 EPLD 192-Macrocell | Altera
MPN: EPM5192LC-M148A ✗ Cuối đờiEPM5192LC-M148A Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks on a single die with a central interconnect matrix. CPLDs are typically used as deterministic, low-latency glue logic: power-up ready, predictable timing, and pin-for-pin replaceable with discrete 74-series logic. In the device taxonomy, EPM5192 sits above a standard PAL and below modern FPGAs, and MAX 5000 specifically was Altera's bridge family between PALs and the later MAX 7000 / MAX II series. The 'LC' suffix denotes a low-power CMOS process variant and the 'M148A' package code designates the 148-pin package used for the LC speed grade.
Key features include 192 macrocells organized across multiple logic array blocks, 148 user I/O pins, 5-V tolerant I/O, and propagation delays measured in tens of nanoseconds, which is well-suited to bus and control-plane logic. The device is in-system programmable via Altera's classic MAX+PLUS II / Quartus toolchains, with JTAG support depending on the exact die revision. The 148-pin package gives designers significant pin resources for wide bus bridges and parallel state machines. Architecturally, MAX 5000 uses a global interconnect with predictable tPD/tCO timing, making it easier to constrain than SRAM-based FPGAs.
Typical applications include industrial control logic replacement, legacy telecom backplane glue logic, address decoding for 8/16/32-bit microprocessor boards, peripheral bus interfaces, and power-up configuration sequencing for ASIC/FPGA systems. The wide I/O count and 5-V tolerance make it especially useful as a bridge between 5-V legacy peripherals and modern 3.3-V controllers.
When designing with this part, confirm the package code against the 148-pin PCB footprint before laying out a board; the LC speed grade denotes specific tPD numbers per Altera's MAX 5000 datasheet. Because the part is a mature, legacy device, current lead times and stock vary significantly and may require sourcing through brokers. Engineers should validate revision against the original Altera datasheet and check for any last-time-buy notices before committing to new production.

Ứng dụng tiêu biểu
EPM5192LC-M148A phù hợp cho 6 Áp dụngs: Legacy Industrial Control Logic Replacement, Telecom Backplane Glue Logic, Microprocessor Address Decoding, Peripheral Bus Bridge / Interface Logic, Power-Up Configuration Sequencing for ASIC/FPGA Systems, Aerospace / Avionics Legacy Maintenance.
Legacy Industrial Control Logic Replacement
The EPM5192LC-M148A's 192 macrocells and 148 user I/O pins make it a strong fit for replacing dozens of discrete 74LS/74HC logic packages on legacy industrial control boards. Its UV-erasable / OTP non-volatile architecture means the design powers up in a known deterministic state within nanoseconds, critical for fail-safe industrial PLC backplanes where SRAM-based FPGAs cannot tolerate configuration delays. The 5-V tolerant I/O allows direct interfacing to 5-V sensor and actuator drivers without level shifters, simplifying retrofits of older factory-floor equipment. Because the part is from the mature MAX 5000 family, it is widely second-sourced through brokers for maintenance, repair, and operations (MRO) of installed machinery.
Được đề xuất
Telecom Backplane Glue Logic
The EPM5192LC-M148A is well suited to telecom backplane glue logic because its wide I/O count can bridge multiple parallel buses on a single non-volatile device. Its deterministic tPD/tCO timing across 192 macrocells allows precise bus-arbitration and address-decoding logic without the jitter and configuration latency of an FPGA. The 148-pin package supports 16-bit and 32-bit wide address and data buses with spare pins for parity, interrupts, and chip-select signals. For legacy telecom systems still in service, the EPM5192LC-M148A provides a known-stable logic element with predictable timing and broad broker availability for emergency repair scenarios.
Được đề xuất
Microprocessor Address Decoding
With 192 macrocells, the EPM5192LC-M148A can decode the full 24-bit or 32-bit address space of legacy 8-bit, 16-bit, and 32-bit microprocessors in a single device. Each macrocell can implement a sum-of-products decode equation, replacing entire banks of discrete AND/OR gate packages. The 148 user I/O pins comfortably support the chip-select fan-out typical of Motorola 68000, Intel 8086, or Zilog Z80-based designs, plus peripheral control lines. Power-on deterministic decoding eliminates the boot race condition that occurs when SRAM FPGAs are used for chip-select generation in cold-start microprocessor systems.
Được đề xuất
Peripheral Bus Bridge / Interface Logic
The EPM5192LC-M148A acts as a flexible protocol bridge between legacy 5-V peripherals and modern 3.3-V controllers because every I/O is 5-V tolerant and the macrocell fabric can implement parallel state machines in hardware. Engineers frequently use it to translate ISA bus signals to custom peripheral interfaces, generate timing waveforms for parallel-port peripherals, or emulate proprietary bus protocols no longer supported by modern ASICs. The 192-macrocell capacity covers most ISA-to-PCI bridge glue designs, and the 148-pin count leaves headroom for status LEDs, debug headers, and boundary-scan JTAG pins on the production board.

Power-Up Configuration Sequencing for ASIC/FPGA Systems
The EPM5192LC-M148A is ideal for power-up configuration sequencing because it is non-volatile and powers up in a defined state within nanoseconds, while SRAM-based FPGAs need milliseconds to load their bitstream. Using its 192 macrocells and 148 I/O pins, designers implement a multi-rail power sequencer that asserts enable signals to downstream DC-DC converters in a controlled order, monitors PGOOD flags, and holds downstream FPGAs in reset until all rails are stable. The OTP architecture guarantees the sequencer itself cannot be misprogrammed by supply transients, a key requirement for safety-critical and aerospace electronics.
Được đề xuất
Aerospace / Avionics Legacy Maintenance
The EPM5192LC-M148A family sees continued demand in aerospace and avionics MRO because many legacy flight-control and instrument panels were designed around MAX 5000 EPLDs that are still fielded today. The MIL-processed EPM5192GM/883B and industrial-grade EPM5192JI variants share the same die and footprint, simplifying DO-254-qualified repair workflows. The 192-macrocell capacity is sufficient for ARINC 429 bus decoding, discrete-to-digital conversion, and redundant control logic on flight-deck instrumentation where re-design is cost-prohibitive.

Bảo phân biệt quan trọng
- Highest macrocell count in the MAX 5000 family (vsEPM5130 / EPM5128 / EPM5064 / EPM5032 / EPM5016)
- 148-pin M148A package supports widest bus interfaces (vsEPM5192GM / EPM5192JC (smaller-pin packages))
- Non-volatile UV/OTP architecture powers up in known state (vsSRAM-based FPGAs (e.g. Cyclone, MAX 10))
Ghi chú thiết kế
Because the EPM5192LC-M148A is a legacy Altera MAX 5000 part, modern Intel Quartus Prime versions no longer support it; design entry must use the legacy MAX+PLUS II toolchain or an older Quartus release that still includes MAX 5000 device support. Engineers porting a new design should plan tooling migration up-front and archive the original MAX+PLUS II project files because the latest Quartus toolchains will refuse to open MAX 5000 projects silently.
The MAX 5000 family draws all I/O current from VCC; place at least one 0.1 uF decoupling capacitor per VCC pin (typically three VCC pins on a 148-pin MAX 5000 die) and a bulk 10 uF tantalum near the supply entry. UV-erasable parts in particular are sensitive to VCC droop during programming pulses - if you are erasing through a quartz window, ensure the programming supply is well regulated to within 5 percent of nominal.
Estimated: on a 4-layer PCB with 148 pins in a PGA-style footprint, allow at least 6 oz copper or a copper pour under the package to dissipate the LC variant's typical 0.5-1.5 W quiescent power; the exact theta_JA is package-dependent and should be checked against the Altera MAX 5000 datasheet. Pin 1 marker placement must match the original Altera package diagram (top-left with the dot marker) - a mirrored footprint will not program or operate correctly because the JTAG and configuration pins are position-sensitive.
Although the MAX 5000 outputs are 5-V TTL-compatible, fast edges on heavily loaded address/data buses (above 8 mA per pin) can produce significant ground bounce. Place the EPM5192LC-M148A's GND pins directly above a solid ground plane and use short traces to high-current outputs; if the design toggles 32-bit-wide buses at high frequency, consider a 33-ohm source-termination resistor on each byte group to control ringing.
Thông tin tuân thủ
Compliance data not present in verified web sources - MAX 5000 family predates widespread RoHS reporting and the LC suffix denotes CMOS process, not lead-free status. MIL-processed variants (EPM5192GM/883B) carry MIL-STD-883 processing certification rather than commercial compliance marks.
