EPM7128SLC84-7N Présentation
A Complex Programmable Logic Device (CPLD) is a non-volatile, in-system programmable logic IC that bridges the gap between discrete logic gates and full FPGAs. CPLDs use EEPROM or flash memory cells to store their configuration, retaining bitstream through power cycles without external boot memory. Architecturally, CPLDs belong to the programmable logic hierarchy (CPLD -> PLD -> programmable logic -> digital IC -> semiconductor) and are typically deployed for glue logic, bus bridging, state-machine control, and I/O expansion where deterministic timing and instant-on behavior matter more than raw logic density.
Key features of the EPM7128SLC84-7N include 128 macro cells organized into 8 logic array blocks (LABs), 68 user I/O pins, in-system programmability (ISP) via JTAG, and counter speeds up to 175.4 MHz on faster speed grades. The MAX 7000S second-generation MAX architecture integrates a programmable interconnect array (PIA) that routes signals between LABs with predictable timing, eliminating the routing-variation problem of early PLDs. Built on advanced CMOS EEPROM technology, the device offers 100% TTL-compatible I/O and supports hot-socketing for legacy bus designs.
Typical applications include 5V bus-interface glue logic in industrial control boards, address decoding and interrupt steering in embedded motherboards, legacy peripheral replacement for 74LS/74F TTL logic, state-machine controllers for motor drives, and I/O expansion around microcontrollers and DSPs. The wide 5V tolerance also makes it suitable for prototyping legacy PC/104 and VMEbus systems.
When designing with this device, ensure that the JTAG pins (TDI, TDO, TMS, TCK) are properly terminated and that the input ramp time on VCC respects the EEPROM programming requirements. The 84-pin PLCC package requires a socket or hand-soldered footprint; for new designs consider the modern MAX II or MAX V equivalent. Power dissipation scales with the toggle rate of the programmed logic and the output loading.

Applications typiques
EPM7128SLC84-7N convient pour 6 applications: 5V Bus Glue Logic in Industrial Control, Address Decoding and Interrupt Steering, Legacy TTL Replacement (74LS/74F), Motor Drive State-Machine Controller, I/O Expansion Around Microcontrollers, Prototype and Educational Logic Platform.
5V Bus Glue Logic in Industrial Control
The EPM7128SLC84-7N is well-suited to 5V bus-interface glue logic in industrial control boards, where its 128 macro cells replace multiple 74LS/74F TTL packages and the 7.5 ns tpd provides deterministic timing for ISA, PC/104, and legacy VMEbus signaling. Its 68 I/O pins comfortably address- decode a full 24-bit address bus plus a parallel data path, while in-system programmability via JTAG lets technicians rework the logic without removing the chip. Compared to a discrete TTL implementation, this CPLD cuts board area by 70 percent and eliminates cross-chip timing skew.
Recommandé
Address Decoding and Interrupt Steering
In embedded motherboards the EPM7128SLC84-7N consolidates address decoding, chip-select generation, and interrupt steering into a single non-volatile device that boots instantly with no FPGA configuration delay. The 2,500 usable gates handle a full 32-bit decode tree with multiple chip enables, while the 7.5 ns propagation delay ensures setup/hold margin for 50 MHz legacy buses. Because the configuration is stored in on-chip EEPROM, no boot PROM is required, reducing BOM cost and board complexity.
Recommandé
Legacy TTL Replacement (74LS/74F)
Engineers migrating from discontinued 74LS and 74F discrete TTL can consolidate 20 or more SSI/MSI packages into one EPM7128SLC84-7N, achieving the same logic in 70 percent less board area with lower power and zero skew between signals. The 5V TTL-compatible I/Os interface transparently to legacy 5V peripherals without level shifters, while the 128 macro cells and 8 LABs map cleanly to most decode, latch, and small state-machine patterns. Quoted power savings are typical 40 percent versus equivalent discrete TTL implementations.
Recommandé
Motor Drive State-Machine Controller
The EPM7128SLC84-7N's deterministic 7.5 ns tpd makes it a reliable state-machine controller for stepper and brushless DC motor drives, where commutation sequences must be generated with low jitter and predictable latency. Its 68 I/Os drive H-bridge gate drivers, encoder inputs, and Hall-sensor feedback paths from a single chip, while EEPROM-based non-volatile storage retains the commutation table across power cycles. Designers typically pair it with discrete gate drivers and an external MCU for closed-loop torque control.
Recommandé
I/O Expansion Around Microcontrollers
Around a low-pin-count MCU or DSP, the EPM7128SLC84-7N expands the I/O count by 68 pins, offloads timing-critical tasks like PWM generation, quadrature decoding, and SPI/I2C bridging, and consumes minimal quiescent current. The JTAG-based in-system programmability allows field updates without removing the chip, and the 5V tolerance matches legacy industrial MCU rails. The combination is popular in factory automation retrofits where 5V MCU inventory remains in service.
Recommandé
Prototype and Educational Logic Platform
The EPM7128SLC84-7N remains a staple in university embedded systems laboratories and prototype labs because the 84-pin PLCC socket allows easy insertion/removal on a breadboard or training board. Its 128 macro cells comfortably host introductory finite state machines, custom instruction decoders, and bus-interface experiments, while the 5V supply matches common lab power rails. The well-documented MAX+PLUS II / Quartus legacy toolchain keeps the part accessible for teaching non-volatile programmable logic fundamentals.

Notes de conception
The EPM7128SLC84-7N requires a 4.75 V to 5.25 V supply on VCCINT (pin 21 and pin 76) and VCCIO (pin 33) with decoupling: place one 0.1 uF ceramic capacitor as close as practical to each VCC pin plus a single 10 uF tantalum or aluminum bulk capacitor at the supply entry. During in-system programming the EEPROM array draws transient current up to ~150 mA per VCC pin, so the bulk capacitor prevents VCC sag. Estimated: Icc (standby) is approximately 10-30 mA per the legacy datasheet family characterization.
Place the PLCC-84 socket on the top side with the orientation dot aligned to pin 1 marker; reserve clearance for the J-lead bend radius (approximately 0.8 mm). Route JTAG signals (TDI/TDO/TMS/TCK on pins 43/81/44/45) as a short bus with a 10 kohm pull-up on TMS and TCK to VCCIO to keep the TAP controller in a defined state at power-up. Avoid routing sensitive analog signals under the socket cavity to prevent crosstalk from the switching I/O transitions.
Do not mix EPM7128SLC84-7N with non-'N' lead-bearing variants on a RoHS-certified board; the 'N' suffix is mandatory for European CE compliance. When migrating from MAX 7000S to MAX 7000E (e.g., EPM7128ELC84-10), recompile the design with MAX+PLUS II or Quartus - the macro cell timing and JTAG BSDL differ slightly. Ensure VCCINT rise time is monotonic and exceeds 1 ms to avoid EEPROM programming faults during ISP.
Estimated: at maximum toggle activity on all 68 outputs driving 50 pF loads at 10 MHz, the PLCC-84 dissipates approximately 0.6 W with theta_JA around 35 C/W (still-air), giving a junction rise of ~21 C. The commercial 0 C to +70 C range leaves comfortable margin without a heatsink. In enclosed industrial cabinets, derate toggle frequency or provide 100 LFM airflow to keep Tj below 100 C.
Informations de conformité
