Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EPM5192LC-M091A is suitable for 6 applications: Legacy 5V Industrial Glue Logic, VMEbus Address Decoding, MIL-STD-1553 Bus Interface Logic, Legacy Telecom Backplane Glue, Microprocessor Peripheral Interface Consolidation, Replacing Discrete PAL/GAL Arrays.
Legacy 5V Industrial Glue Logic
The EPM5192LC-M091A's 192 macrocells and 5V-tolerant architecture make it ideal for consolidating discrete 22V10/16V8 PAL/GAL glue logic on legacy industrial control boards. With 64 user I/O pins and 12 LABs interconnected by a Programmable Interconnect Array, a single part can replace an entire board of SSI/MSI logic for bus decoding, interrupt steering, and address mapping. The UV-erasable non-volatile configuration ensures instant-on operation in factory automation PLCs and motor controllers, where boot delays from SRAM FPGAs are unacceptable.
Recommended
VMEbus Address Decoding
The EPM5192LC-M091A fits VMEbus address-decoding applications where 64 user I/O pins can monitor the full 32-bit VME address bus plus control signals in a single device. Its 192 macrocells easily implement the multi-level address decoder state machine needed for VMEbus system controllers, with deterministic tpd that fits within the 55 ns typical budget of legacy VME cycles. Non-volatile configuration allows the system controller to come up active before the host CPU finishes its reset sequence, which is critical in VME chassis initialization.
Recommended
MIL-STD-1553 Bus Interface Logic
MIL-STD-1553 avionics bus interfaces benefit from the EPM5192LC-M091A's combination of 5V operation, deterministic timing, and the LC military-style package option that supports the M091A customer-specific screening flow. With 192 macrocells, designers can integrate Manchester encoder/decoder glue logic, RT address detection, and bus controller message framing on one device, reducing board area and EMI. The non-volatile EPROM-based configuration survives power cycles without external boot memory, essential in avionic cold-start scenarios.
Recommended
Legacy Telecom Backplane Glue
Telecom backplanes built on 5V TTL logic benefit from the EPM5192LC-M091A's 192 macrocells to consolidate address decoding, interrupt steering, and bus arbitration across multiple line-card slots. The PIA-based interconnect provides predictable timing so backplane handshakes meet setup/hold margins under all loading conditions. With 64 user I/O pins plus 7 dedicated inputs, a single part can service the address, data, and control signals of an entire line-card interface.
Recommended
Microprocessor Peripheral Interface Consolidation
The EPM5192LC-M091A's 192 macrocells can replace multiple 74LS/74FTTL glue-logic chips interfacing 8/16/32-bit microprocessors to memory, peripherals, and bus arbiters. With 64 user I/O pins, designers can implement chip-select decoding, wait-state generation, and bus-transceiver control on a single 5V device. Its non-volatile configuration eliminates the boot-time delay of SRAM-based FPGAs, which is critical in embedded controllers that must respond to interrupts immediately after reset.
Recommended
Replacing Discrete PAL/GAL Arrays
The EPM5192LC-M091A directly targets the consolidation of multiple 20-pin/24-pin PAL or 22V10/26V12 GAL devices onto a single 192-macrocell EPLD, reducing board area, power, and programming logistics. Each of the 192 macrocells can be configured as combinatorial or registered logic with selectable flip-flop mode, replicating the function of an entire discrete PAL array. The 5V supply eliminates level-shifters that would otherwise be needed when migrating 5V PAL/GAL designs to 3.3V CPLDs.

Key Differentiators
- Customer-specific M091A test/screening code (vs EPM5192LC)
- Largest macrocell density in MAX 5000 family (vs EPM5130LC (130 macrocells))
- Deterministic PIA interconnect timing (vs MAX V (5M570Z) CPLD)
Design Notes
Do not assume the LC package follows a JEDEC-standard outline. The LC suffix denotes a customer-specific pin-grid package used in legacy Altera MAX 5000 designs, and the M091A designator further customizes the test pattern. Before laying out a new PCB, request the M091A mechanical drawing from your distributor and confirm the pin numbering matches the standard MAX 5000 LC convention documented in the generic EPM5192 datasheet. Skipping this check is a common cause of pin-out mismatch on obsolete Altera EPLDs.
The EPM5192LC-M091A is supported only by the legacy Altera MAX+PLUS II toolchain; modern Quartus Prime does not support MAX 5000 devices. Ensure your design flow can compile, simulate, and program using MAX+PLUS II, which is no longer distributed by Intel. Archived MAX+PLUS II versions can be found on FPGA developer forums but may not run on 64-bit Windows. For new designs, prefer MAX V (5M240Z/M570Z) which is supported by current Quartus Prime.
Estimated: at 5V Vcc with all 64 I/O toggling at 10 MHz and 30 pF loads, the EPM5192LC-M091A draws roughly 250-400 mA active supply current, dissipating 1.25-2 W. For the LC ceramic/military-style package, theta_JA is approximately 30-40 C/W depending on socket and airflow, so a 2 W dissipation results in a 60-80 C junction temperature rise above ambient. In enclosed avionic or industrial chassis, derate by 50% or add thermal vias under the package to keep Tj below 125 C for military-grade operation.
Use 5V CMOS-series termination (typically 33-100 ohm series resistors) on high-speed outputs when driving long traces or backplane stubs above 50 MHz equivalent edge rates. The PIA-based interconnect has predictable delays but does not buffer outputs, so heavily-loaded I/O can suffer from ground bounce. Decouple each VCC pin with a 0.1 uF ceramic plus a 10 uF tantalum bulk capacitor placed within 5 mm of the package pin for stable 5V operation.
Compliance Information
LC package and M091A customer-specific suffix suggest military/extended-temperature use; specific RoHS/REACH/lead-free status for EPM5192LC-M091A is not available in the verified web data and is marked [DATA_NEEDED]. Parts from this legacy family typically predate widespread RoHS conversion, so many LC variants are non-RoHS unless explicitly labeled Pb-free.
