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
EPM7096LI68-15 is suitable for 6 applications: 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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.

Key Differentiators
- Drop-in compatible with EPM7096LC68-15 for inventory bridge (vs EPM7096LC68-15)
- Faster speed grade available in same PLCC-68 footprint (vs EPM7096LC68-7)
- Higher I/O count available with larger PLCC-84 package (vs EPM7096LC84-15)
Design Notes
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.
