EPM7096LC68-7 - 96-Macrocell MAX 7000 CPLD, 7.5ns | Intel
MPN: EPM7096LC68-7 ✗ Cuối đờiEPM7096LC68-7 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the broader programmable logic hierarchy between simple SPLDs (like GAL/PAL) and high-capacity FPGAs. CPLDs use EEPROM or flash cells to retain configuration, provide deterministic timing with predictable pin-to-pin delays, and typically contain hundreds of macrocells grouped into LABs interconnected by a programmable interconnect matrix (PIA). They are commonly chosen for applications needing instant-on behavior, robust I/O driving capability, and small-form-factor logic integration at low power. Within the programmable logic taxonomy, the MAX 7000 family sits as one of the longest-lived mainstream 5 V EEPROM CPLD lines introduced by Altera (now Intel).
Key features of the EPM7096LC68-7 include 5.0 V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, a maximum toggle frequency that supports common bus-interface speeds, six dedicated global clock pins, and a programmable power-saving mode that reduces quiescent current on unused macrocells. Each macrocell contains a programmable AND/OR array with a flip-flop, providing both combinational and registered logic in a single architectural unit. The LC68 (PLCC-68 J-lead) package is socket-compatible across the MAX 7000 series, enabling board reuse between density variants.
Architecturally, the MAX 7000 uses a second-generation MAX architecture with enhanced interconnect routing and per-macrocell product-term allocation. The four LABs share a Programmable Interconnect Array (PIA) that routes any LAB output to any other LAB input, removing routing bottlenecks common to older PLD families. Combined with the 52 I/O pins, the device delivers sufficient logic density for 16-/32-bit bus decoding, address-latch multiplexing, and peripheral control blocks in legacy 5 V systems.
Typical applications include 5 V ISA bus decoding, industrial PLC I/O expansion, peripheral glue logic in telecom line cards, address/data multiplexing for microprocessors without integrated peripherals, and pin-compatible board upgrades from smaller MAX 7000 devices (EPM7032, EPM7064, EPM7128). The part is widely used for new designs targeting legacy 5 V rails and for long-lifecycle industrial equipment maintenance where firmware-updateable logic simplifies field upgrades.
When designing with this part, allow at least one 0.1 uF decoupling capacitor per VCC/GND pair, place the JTAG TMS/TCK/TDO/TDI chain with proper pull-ups, and verify the device programming file (POF/JEDEC) targets the correct speed grade (-7 = 7.5 ns tPD). Note that EPM7096LC68-7 is generally considered a legacy/NRND device; engineers should confirm long-term availability before new design-in.

Ứng dụng tiêu biểu
EPM7096LC68-7 phù hợp cho 6 Áp dụngs: ISA Bus Address Decoding, Industrial PLC I/O Expansion, Peripheral Glue Logic in Telecom Line Cards, Microprocessor Address/Data Multiplexing, Legacy 5 V System Board Upgrades, Custom State-Machine Controllers.
ISA Bus Address Decoding
The EPM7096LC68-7 is well suited for ISA bus address decoding in legacy 5 V PC/104 and embedded computing platforms. With 96 macrocells it can decode the full 16-bit or 24-bit ISA address space and generate multiple chip-select signals, while the 7.5 ns tPD meets the ISA 8.33 MHz bus timing budget without inserting wait states. Place the CPLD between the ISA bus and peripheral chip-select lines; its 5 V tolerant I/O matches ISA signal levels directly. Compared with discrete 74-series decoder logic, the CPLD integrates the equivalent of dozens of decode gates into one package, reducing board area and BOM cost.
Được đề xuất
Industrial PLC I/O Expansion
The EPM7096LC68-7 serves as a flexible I/O expander and signal-conditioning block in 5 V industrial PLC designs. Its 52 user I/O pins and 96 macrocells can scan and debounce multiple discrete-input channels while driving relay or optocoupler outputs through sequenced logic. The EEPROM non-volatile configuration means PLCs boot instantly into known states, which is critical for industrial safety and deterministic startup. The -40C to +85C operating range supports factory-floor environments. Compared with microcontroller-based I/O, the CPLD's deterministic timing eliminates firmware-task scheduling jitter.
Được đề xuất
Peripheral Glue Logic in Telecom Line Cards
The EPM7096LC68-7 integrates bus-bridge, chip-select, interrupt-arbitration, and reset-sequencing logic for telecom line cards where multiple processors, ASICs, and DSPs must communicate over shared buses. With 96 macrocells the CPLD can implement several independent glue-logic functions that would otherwise require dozens of 74LVTH/74FCT packages, reducing board complexity and improving signal integrity. The 7.5 ns tPD easily handles 33-50 MHz local bus speeds, and the JTAG ISP allows in-system updates as line-card firmware evolves.
Được đề xuất
Microprocessor Address/Data Multiplexing
The EPM7096LC68-7 is used to multiplex and demultiplex address and data buses in designs where the host microprocessor (e.g., 8051, 80188, or older Motorola 68000) lacks an integrated external bus interface unit. With 96 macrocells it can implement 16-bit address-latch multiplexing, byte-enable steering, and ready/wait-state insertion in a single device. The 7.5 ns tPD meets the setup/hold windows of common 8/16-bit microprocessors at full speed, and the LC68 socket footprint allows straightforward board layout.
Được đề xuất
Legacy 5 V System Board Upgrades
The EPM7096LC68-7 is a drop-in upgrade for legacy boards originally populated with smaller MAX 7000 devices such as the EPM7032 or EPM7064. Because all LC68 MAX 7000 parts share the same 68-pin J-Lead PLCC socket footprint, designers can scale logic density up or down by simply swapping the part without PCB rework. This makes the EPM7096LC68-7 ideal for field-upgrade programs where new firmware requires additional glue-logic capacity. The EEPROM non-volatile configuration also means no external boot PROM is needed, simplifying the BOM.
Được đề xuất
Custom State-Machine Controllers
The EPM7096LC68-7 is used to implement complex state machines for embedded controllers, motor-control sequencers, and protocol bridges where a microcontroller is overkill or where deterministic hardware timing is required. Each of the 96 macrocells can host a flip-flop with programmable set/reset, and the LAB-based architecture allows easy state-machine partitioning. With 6 global clock pins the CPLD can synchronize multiple independent state machines to different clocks, and the JTAG ISP enables in-field state-machine updates.

Ghi chú thiết kế
The EPM7096LC68-7 requires a stable 5.0 V supply with decoupling placed close to every VCC/GND pair. Recommended: one 0.1 uF ceramic capacitor per VCC pin (pins 9, 30, 40, 53) plus one bulk 10-100 uF tantalum or aluminum electrolytic capacitor at the board supply input. The CPLD draws significantly higher current during JTAG programming, so verify the 5 V regulator can supply at least 500 mA peak. Place the decoupling within 5 mm of the VCC pins to minimize inductance.
Route JTAG signals (TMS, TCK, TDI, TDO on pins 27-29 and 32) as a daisy-chain with proper 10 kohm pull-ups on TMS, TDI, and TCK. Keep JTAG traces short (under 100 mm) and away from switching power or high-current signals to avoid programming failures. For sockets, use a quality PLCC-68 thru-hole socket with retention clips; the J-lead PLCC package is mechanically fragile and a socketing approach eases field replacement. Maintain continuous ground planes under the package to reduce EMI.
Do not confuse the EPM7096LC68-7 (5.0 V) with 3.3 V MAX 7000A or MAX 7000B variants - mixing voltage rails can damage the device. Verify the speed-grade suffix matches your timing budget: -7 = 7.5 ns, -10 = 10 ns, -15 = 15 ns. Using a slower speed grade than required is fine; using a faster one is also fine but typically costs more. The JTAG programming file must be compiled for the specific device ID; a JEDEC file for EPM7064 will NOT work on EPM7096.
The EPM7096LC68-7 is a 5 V CMOS device with relatively slow edge rates compared to modern logic, so signal-integrity issues are usually limited to heavily-loaded outputs. For outputs driving more than 4-6 loads or cables, add a 22-33 ohm series damping resistor near the CPLD pin. The 52 user I/O pins can be configured for 5 V TTL-compatible I/O levels, but verify the receiver device's VIH/VIL thresholds are met when interfacing with 3.3 V peripherals - level translation may be required.
