A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the architectural simplicity of PAL/GAL devices with much higher macrocell density and deterministic timing. CPLDs occupy the middle tier of programmable logic hierarchy - below FPGAs in raw density but above simple SPLDs/PALs - and are commonly classified within the broader category of programmable logic devices (PLDs) and digital semiconductors. The MAX 7000 family uses a classic EEPROM-based architecture, meaning configuration is retained without external memory and the device is in-system programmable (ISP) through a built-in IEEE 1149.1 JTAG interface.
Key features of the EPM7096LI68-15 include 96 macrocells, 4 logic array blocks, 52 I/O pins, 15ns combinatorial propagation delay, 5.0V in-system programmability via JTAG, open-drain output option, and built-in JTAG boundary-scan test (BST) circuitry. Each macrocell provides a programmable register with dedicated product-term logic, supporting classic sum-of-products glue-logic applications. The device operates from a single 5V supply and supports both 3.3V and 5.0V I/O standards when used with the appropriate configuration.
From a technical depth perspective, the MAX 7000 architecture uses a global interconnect that routes every LAB signal to every other LAB through a single fast connective path. Each LAB contains 16 macrocells and an I/O block. The 'L' suffix indicates the low-power variant and the 'I' suffix denotes industrial temperature grade. The -15 speed grade sets tPD (pin-to-pin) at 15ns, suitable for 33 MHz-66 MHz state-machine and decoder-style glue logic.
Typical applications include bus interface bridging, address decoding, state-machine control, peripheral glue logic in microcontroller/ASIC systems, and legacy industrial control replacement. The JTAG ISP capability makes board-level upgrades and field reprogramming practical without removing the device from the circuit.
When designing with the EPM7096LI68-15, observe PLCC-68 PCB layout guidelines including proper land pattern per JEDEC MS-018, decoupling capacitor placement near VCC pins, and JTAG chain integration if multiple devices share the same boundary-scan test port. Note that this part is now in legacy/end-of-life status - check Intel FPGA product lifecycle notices before new designs.

عام استعمالات
EPM7096LI68-15 کے لیے موزوں ہے 6 ایپلیکیشنs: Bus Interface Bridging, Address Decoding & Chip-Select Generation, State-Machine Control Logic, Legacy Industrial Control Replacement, Glue Logic for Microcontroller/ASIC Systems, Peripheral Multiplexing & Signal Conditioning.
Bus Interface Bridging
The EPM7096LI68-15's 96 macrocells and 52 user I/O pins make it well-suited to bridge between microcontrollers, ASICs, and peripheral buses. The 15ns pin-to-pin delay comfortably meets the timing budgets of 8-bit and 16-bit microcontroller interfaces (e.g., 8051, 68k) and legacy ISA-style buses, while the JTAG ISP capability allows field reprogramming to fix hand-shake mismatches discovered during integration. With 5V tolerant I/O, it can sit directly on legacy 5V buses without level shifters - a key advantage over modern 3.3V-only MAX V replacements that would require bus re-architecting.

Address Decoding & Chip-Select Generation
The EPM7096LI68-15's sum-of-products macrocell architecture and 15ns propagation delay are ideal for multi-bank memory address decoding and chip-select generation in microprocessor systems. Each of the 96 macrocells implements an AND-OR logic function, with the product-term allocator distributing up to 5 product terms per macrocell. Engineers can decode large memory maps (e.g., 24-bit address space yielding 8 wait-state chip selects) in a single device. The 5V I/O tolerance allows direct interface to legacy memory chips like 27C256 EPROM, 62256 SRAM, and peripheral controllers.

State-Machine Control Logic
For FSM-based control of motors, displays, or industrial machinery, the EPM7096LI68-15 provides 96 macrocells each with a programmable D/T/JK flip-flop, supporting one-hot, binary, or Gray-coded state machines of up to ~20 states per device. Industrial temperature grade (-40C to +85C) and 5V I/O tolerance make it ideal for factory-floor PLC interfaces, where ambient temperatures can range widely. The deterministic 15ns timing eliminates the metastability concerns of asynchronous CPLD/FPGA designs and supports clean synchronous control loops at clock rates up to ~66 MHz.

Legacy Industrial Control Replacement
When repairing or refurbishing legacy industrial equipment (CNC controllers, PLCs, medical instruments), the EPM7096LI68-15 is often the only practical replacement for original Altera MAX 7000 CPLDs that have reached end of life. Its pin-compatible package and JTAG ISP enable drop-in PCB replacement without firmware rewrite - engineers program the new device with the original JEDEC file. The industrial temperature grade and proven 5V tolerance match the operating envelope of 1990s-2000s industrial systems still in service worldwide. Authorized distributor stock supports bridge supply until full system redesign.

Glue Logic for Microcontroller/ASIC Systems
Modern MCUs and ASICs rarely match their I/O requirements perfectly - the EPM7096LI68-15 fills the role of 'glue logic' between mismatched interfaces, e.g., converting parallel MCU ports to SPI/I2C master controllers, generating timing-critical waveforms, or implementing custom interrupt controllers. The 96 macrocells handle complex glue functions in a single device, replacing multiple 74-series TTL packages and saving PCB area. The 5V I/O directly interfaces with both 5V TTL/CMOS peripherals and 3.3V devices when 5V tolerance is acceptable.
تجویز کردہ
Peripheral Multiplexing & Signal Conditioning
Systems with more peripheral chips than MCU I/O pins benefit from the EPM7096LI68-15 as a peripheral multiplexer. The 52 user I/O pins and bidirectional I/O blocks allow dynamic re-routing of peripheral signals under firmware control, while the open-drain output option directly drives I2C or wire-OR interrupt lines without external transistors. The 15ns propagation delay is short enough to handle 10-20 MHz peripheral buses without hold-time violations, making the part common in mid-2000s embedded designs that now need lifecycle support.

ڈیزائن نوٹس
The EPM7096LI68-15 requires a stable 5.0V +/- 5% supply with adequate decoupling. Place a 0.1uF ceramic capacitor close to each VCC pin (pins 15, 35, 58) and a single 10uF tantalum or low-ESR ceramic bulk capacitor near the device. Per the MAX 7000 datasheet, ICC (active supply current) scales with toggle frequency and the number of active macrocells - typical ICC is ~30-50 mA at low toggle rates and can reach ~150 mA when all 96 macrocells toggle at full speed.
PLCC-68 land patterns must follow JEDEC MS-018 with all 68 J-leads properly soldered. Ensure no voids under the thermal pad area (this device has no exposed pad - thermal dissipation is through the leads and the small amount of top-side copper). For JTAG chains with multiple devices, route TCK/TMS/TDI as daisy-chain and place a 10k pull-up on TMS and TDI per IEEE 1149.1 recommendations.
Three pitfalls to avoid: (1) Do NOT assume pin-to-pin compatibility between 68-pin PLCC and 84-pin PLCC variants of the EPM7096 - the extra 12 pins on PLCC-84 add additional I/O with different pin assignments, so the 68-pin and 84-pin variants require different PCB designs. (2) Do NOT mix EPM7096 with EPM7128S/EPM7160S without re-validating timing - the 'S' variants add JTAG BST circuitry and have different propagation delay curves. (3) Do NOT program a non-ISP variant expecting JTAG to work - the EPM7096 (non-S) supports ISP via JTAG, but verify your specific ordering code supports ISP before relying on it for field upgrades.
For 33 MHz-66 MHz signal paths through the EPM7096LI68-15, maintain controlled-impedance traces (50 ohm microstrip) on clock inputs (GCLK1/GCLK2 at pins 26 and 51) and observe 3ns rise-time assumptions when calculating setup/hold margins. Output enable signals (OE1 at pin 27 and OE2 at pin 52) should be driven synchronously to prevent glitches - asynchronous OE assertion can produce output race conditions. For bus signals exceeding ~25 MHz, add 22-33 ohm series damping resistors at the CPLD outputs to suppress transmission-line ringing.
