EPM5192C-2 - 192-Macrocell MAX 5000 PLD, 45ns | Altera

What is a CPLD? A Complex Programmable Logic Device (CPLD) is a programmable logic device that sits in the hierarchy between simple PAL/GAL devices and high-density FPGAs. CPLDs offer non-volatile configuration, deterministic timing, instant-on behavior, and predictable pin-to-pin delays, making them ideal for glue logic, bus interfacing, and state-machine replacement in industrial and telecom designs. Within Altera's portfolio, MAX 5000 CPLDs occupy the classic high-density tier, with the EPM5192C-2 serving as the 192-macrocell density point.
Key features include 192 macrocells, 64 I/O lines, a 45 ns propagation delay through the PIA, 50 MHz maximum operating frequency, and a CMOS process for low static power. The device supports in-system programmability through the Altera MAX+ programming environment with industry-standard JTAG interface support. The architecture provides deterministic timing that simplifies timing closure for control-logic and bus-interface functions.
From an architectural standpoint, the EPM5192C-2 uses an EEPROM-based configuration cell that retains programming without external memory, providing instant-on operation at power-up. The 12 LABs each contain 16 macrocells, with the PIA providing uniform routing between blocks to keep interconnect delays predictable. This makes the part well suited for synchronous state machines and address decoding tasks.
Typical applications include bus decoding and address mapping in embedded systems, glue logic between microprocessors and peripherals, industrial control and instrumentation, telecommunications line-card interface logic, and replacement of discrete TTL/CMOS logic on legacy boards.
When designing with this part, verify timing budgets against the 45 ns PIA delay under worst-case commercial conditions and confirm the JTAG chain order when multiple programmable devices share a single boundary-scan port. Older Altera MAX 5000 software (MAX+PLUS II) is required for legacy device support.

典型應用
EPM5192C-2 適用於 6 應用s: Microprocessor Bus Decoding, Glue Logic Replacement, Industrial Control State Machines, Telecommunications Line-Card Interface, Peripheral Interface Bridging, Legacy Board Repair and Sustainment.
Microprocessor Bus Decoding
The EPM5192C-2 fits microprocessor bus decoding applications because its 192 macrocells provide ample product-term capacity for full address-decode logic, while the deterministic 45 ns PIA delay ensures predictable chip-select timing. With 64 user I/O pins and 7 dedicated inputs, the device can decode wide address and control buses on systems up to 50 MHz. The EEPROM-based configuration means the decoder powers up instantly without an external boot PROM, which is critical for systems that must begin servicing interrupts immediately after reset.
推薦
Glue Logic Replacement
The EPM5192C-2 is well suited to replacing scattered discrete TTL/CMOS glue logic on legacy boards because its 192 macrocells can absorb dozens of 74-series functions into a single device. The 64 user I/O pins handle wide bus widths, while the 45 ns propagation delay matches the timing budget of 74LS/74F logic families. Programmable interconnect simplifies board revisions because designers can change logic equations in software without touching the PCB, dramatically reducing iteration cost on industrial and telecom line cards.
推薦
Industrial Control State Machines
The EPM5192C-2 fits industrial control state-machine applications because the MAX 5000 architecture delivers deterministic timing that simplifies state-machine timing closure. With 12 LABs and a 50 MHz fmax, the device can implement complex multi-state controllers while keeping state-transition latency consistent. The 45 ns PIA delay holds across temperature, allowing the controller to operate reliably in factory-floor environments. Designers can encode the entire machine plus auxiliary control logic in one CPLD, reducing board area and improving serviceability.
推薦
Telecommunications Line-Card Interface
The EPM5192C-2 is a good fit for telecom line-card interface logic where deterministic timing and high I/O count are required. Its 192 macrocells can implement framing, alarm monitoring, and line-interface control in one device, while the 64 I/O pins handle parallel backplane data plus serial control signals. The 50 MHz fmax supports standard telecom clock rates, and the instant-on EEPROM configuration eliminates boot-delay concerns. Telecom-qualified drop-in equivalents such as the EPM5192GC extend the design into harsher temperature ranges.
推薦
Peripheral Interface Bridging
The EPM5192C-2 fits peripheral interface bridging because it can host multiple protocol converters simultaneously - for example parallel-to-FIFO bridges, UART glue, or legacy-to-modern bus adapters - on its 192 macrocells and 64 I/O pins. The 45 ns delay budget is compatible with most asynchronous peripheral clock rates below 22 MHz. EEPROM-based programming lets designers field-update interface mappings without replacing the device, which is useful for instrumentation and embedded modules shipped with evolving firmware.
推薦
Legacy Board Repair and Sustainment
The EPM5192C-2 is ideal for legacy board repair and sustainment programs because the obsolete MAX 5000 family is widely supported by independent distributors and brokers as of 2026-09-12. The drop-in PQCC84 footprint of the EPM5192LC-2 and EPM5192GC variants allows field replacements to use modern stock. The deterministic PIA timing means replacement devices are bit-compatible with the original, so replacement does not require re-validation of timing margins on most legacy designs.

- Same 192-macrocell architecture with faster speed grade available (對比EPM5192GC1)
設計說明
The EPM5192C-2 is obsolete, so always confirm stock before committing to a new design. For new designs prefer MAX II CPLDs such as the EPM240T100C5N, which offer higher macrocell counts, lower power, smaller packages, and active lifecycle support. If you must use the EPM5192C-2, design with the deterministic 45 ns PIA delay in mind and never assume a path will be faster than the worst-case PIA delay.
PQCC84 J-lead packages require careful PCB layout - keep at least 0.5 mm clearance under the package body for cleaning and inspection, and provide thermal vias under the center pad if the device dissipates more than 1 W. Use four-layer boards with continuous ground and power planes to control the inductance of the +5 V supply pins, and decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin.
The 45 ns PIA delay is measured under standard load; when driving long PCB traces or heavily loaded buses, derate timing by an additional 5-10 ns to account for trace delay and capacitive loading. Place the EPM5192C-2 close to the devices it interfaces with to keep interconnect short, and use series damping resistors on outputs that drive backplane connectors to control ringing.
合規資訊
Compliance information was not present in the verified web data for EPM5192C-2. PQCC84 is a J-lead ceramic chip-carrier package; parts in this family predate widespread RoHS/REACH disclosure and are generally treated as legacy components. Use EPM5192GC for harsher qualification levels.
