A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-like logic blocks with a central interconnect matrix, sitting in the broader programmable logic hierarchy: CPLD -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Unlike SRAM-based FPGAs, MAX 9000 devices store their configuration in on-chip EEPROM, providing instant-on behavior without external boot memory and making them well suited for deterministic boot-critical applications.
Key features include 25 logic array blocks, 59 maximum user I/Os, 5.0 V VCCINT core supply with TTL-compatible input thresholds that are also 3.3 V tolerant, and a commercial 0C to 70C operating temperature range. The device is fabricated on a 0.35 um EEPROM process that retains configuration for at least 20 years and supports in-system programmability via the JTAG-compliant IEEE Std. 1149.1 boundary-scan interface. The PLCC-84 package offers a JEDEC-standard through-hole-style leaded footprint that simplifies prototyping and rework.
Architecturally, the MAX 9000 family uses a programmable interconnect array (PIA) that routes signals between LABs (Logic Array Blocks), each containing 16 macro cells with shared product-term expanders and I/O control blocks. The EPM9400LC84-15 supports per-pin slew-rate control, programmable ground pins, and JTAG-based in-system programming through dedicated JTAG pins, eliminating the need for a separate EPROM programmer.
Typical applications include bus-interface bridging, address decoding and glue logic for microprocessor systems, peripheral controllers (UART, FIFO, memory controllers), industrial control sequencing, and legacy 5V system replacement of discrete TTL/CMOS logic. The deterministic timing of the EEPROM-based architecture also makes it suitable for safety-critical or hard-real-time control where SRAM-FPGA configuration latency is unacceptable.
When designing with this device, ensure VCC rises monotonically during power-up and that all four dedicated input pins stay above -0.3 V DC. The 5 V VCCINT rail must remain stable; designers should place decoupling capacitors close to every VCC pin and observe the maximum I/O undershoot/overshoot limits stated in the Operating Requirements for Altera Devices Data Sheet.

সাধারণ ব্যবহার
EPM9400LC84-15 এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Microprocessor Glue Logic and Bus Bridging, Address Decoding and Chip-Select Generation, Peripheral Controllers (UART, FIFO, Memory), Industrial Sequencing and Machine Control, Legacy 5V TTL Replacement and Board Refresh, JTAG-Based In-System Programming Test Platforms.
Microprocessor Glue Logic and Bus Bridging
The EPM9400LC84-15's 400 macro cells and 15 ns pin-to-pin delay make it well suited for microprocessor glue logic and bus-bridging applications such as address decoding, chip-select generation, and wait-state insertion between legacy 5V MCUs and peripheral ICs. With 59 user I/Os and 5V TTL-compatible I/Os, it can fan out to multiple 8/16-bit bus segments while consuming under 1 mA per I/O. Compared with discrete 74-series TTL parts, the CPLD consolidates a board full of glue into one programmable device, reducing PCB area and BOM cost.

Address Decoding and Chip-Select Generation
With 8,000 usable gates and 25 LABs, the EPM9400LC84-15 can decode wide memory address buses (24-32 bits) and generate chip-selects for banks of memory, peripheral controllers, and bus transceivers in a single device. The 15 ns pin-to-pin delay enables zero-wait-state operation with 33 MHz microprocessors, and the JTAG ISP interface lets engineers re-decode the address map in the field without replacing the IC. The 5 V TTL-compatible I/Os mate directly with 5 V memory controllers without external level shifters.

Peripheral Controllers (UART, FIFO, Memory)
The 117.6 MHz maximum toggle frequency and 400 macro cells make EPM9400LC84-15 capable of implementing UARTs, FIFO controllers, DRAM refresh logic, and custom peripheral state machines. Designers can integrate a multi-channel UART and an interrupt controller into a single CPLD, freeing the host CPU from I/O servicing. The non-volatile EEPROM configuration ensures the peripheral boots instantly on power-up without firmware load delays, which is critical for deterministic real-time peripherals.

Industrial Sequencing and Machine Control
Inside 0C to +70C control cabinets, the EPM9400LC84-15 implements sequencing logic for assembly lines, packaging machinery, and conveyor control with deterministic 15 ns step times. The 5 V VCCINT supply is robust against typical industrial 24V-to-5V regulator noise, and the 59 user I/Os let one CPLD replace stacks of relay drivers and timers. Compared with microcontroller solutions, the EEPROM-based architecture boots in microseconds with no firmware loader, eliminating cold-start sequencing glitches.

Legacy 5V TTL Replacement and Board Refresh
When refreshing legacy boards built around discrete 74LS/74HC TTL, the EPM9400LC84-15 with 5 V TTL-compatible I/Os and 400 macro cells can replace dozens of small-scale logic ICs with a single in-system programmable device. Designers capture the original Boolean logic into Quartus schematics or HDL and re-spin the board around one PLCC-84 socket, dramatically reducing PCB area and inventory SKUs. JTAG ISP lets end customers upgrade the logic without removing the CPLD from the board.

JTAG-Based In-System Programming Test Platforms
The EPM9400LC84-15's JTAG (IEEE Std. 1149.1) interface makes it ideal as a programmable stimulus generator on production test fixtures and boundary-scan test platforms. Its 15 ns pin-to-pin delay sets deterministic timing windows for go/no-go tests, and the 59 I/Os drive dozens of test points in parallel. Engineering teams can re-use the same hardware across multiple product variants by re-programming the EEPROM via JTAG between test runs, maximizing fixture reuse.

ডিজাইন নোট
The EPM9400LC84-15 requires a monotonic 5.0 V VCCINT supply with a minimum operating voltage of 4.75 V. Place a 0.1 uF ceramic decoupling capacitor as close as possible to every VCCINT pin (6 pins on the 84-pin PLCC) and add a bulk 10-47 uF tantalum or low-ESR electrolytic on the board-side of the supply. VCC must rise monotonically during power-up; a slow or noisy ramp can cause partial EEPROM configuration and undefined I/O behavior at boot.
The 84-pin PLCC package uses a JEDEC-standard 1.27 mm pitch leaded footprint with a central thermal/exposed cavity. Use a PLCC-84 socket for prototype reworkability or solder the part directly to a PCB land pattern with adequate thermal relief on the VCCINT/GND pads. Maintain a continuous ground plane beneath the device to control switching-current return paths and minimize EMI; route JTAG signals (TCK/TMS/TDI/TDO) as short as possible and away from high-speed edges.
Input pins must not undershoot below -0.5 V DC or below -2.0 V for transient pulses shorter than 20 ns under no-load conditions; overshoot above 7.0 V is likewise prohibited. Do not drive the four dedicated inputs (and user I/Os) below -0.3 V. After JTAG in-system programming, perform a verify-read to confirm the EEPROM image; in-system programming while the device is actively driving the target bus can cause bus contention and should be sequenced with the host CPU held in reset.
Estimated: at maximum toggle rate (117.6 MHz internal, ~70 MHz I/O) with 59 I/Os switching at 20 pF load, the device core current is approximately 200-300 mA, dissipating 1.0-1.5 W. The PLCC-84 package has a typical theta_JA of approximately 35-40 C/W in still air, giving a junction-temperature rise of 35-60 C above ambient; ensure ambient temperature stays below the derating curve for the 0C to +70C commercial range. Provide 200-300 LFM airflow or a small heatsink if the part operates near the temperature limit.
কমপ্লায়েন্স তথ্য
RoHS, REACH, lead-free, and halogen-free statuses were not present in the verified web data; the part is obsolete and pre-dates many modern compliance disclosures. AEC-Q100 is not applicable as the part is specified for commercial 0C to +70C operation, not automotive grade.
