EPM7128SLC84-6N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines the deterministic timing of PAL/PLA architectures with the density and macro-cell flexibility of modern FPGAs. Within the broader programmable-logic taxonomy, the CPLD sits between simple SPLDs (PALs/GALs) and high-density SRAM-based FPGAs, offering instant-on behavior (no external boot PROM required) and predictable propagation delays that simplify timing closure for control-plane logic. The MAX 7000S series is one of the industry's longest-lived CPLD families, valued for its low power consumption, 5V tolerance, and ability to absorb wide glue-logic functions into a single package.
Key features of the EPM7128SLC84-6N include 128 macro cells (each containing 16 product terms), 2500 usable system gates, an fMAX of 147.1 MHz, four dedicated inputs (for high-speed clocking), two global clocks, and JTAG-compliant IEEE 1149.1 boundary-scan support. The 6 ns speed grade represents one of the fastest bins in the MAX 7128 family, making it suitable for memory-interface controllers, address decoding, and peripheral glue where sub-10 ns response is required.
Typical applications include ISA/PCI bus interface logic, peripheral address decoding, microcontroller I/O expansion, state-machine-based control, and legacy 5V industrial systems. The non-volatile EEPROM cell array eliminates the need for external boot memory, supporting instant-on configuration at power-up.
Designers should note that the EPM7128SLC84-6N is a legacy part approaching end-of-life for new designs; production volumes continue for maintenance, but long-term availability for new programs should be confirmed via distributor channels. Pin-compatible speed-grade variants (EPM7128SLC84-7, -10, -15) and identical-die QFP packages (EPM7128SQC100, EPM7128BTC100) exist for design flexibility.
This page synthesizes drop-in alternative listings, parametric comparisons against same-family MAX 7000S variants, and practical design notes (power sequencing, ISP/JTAG usage, 5V mixed-signal considerations) that go beyond the basic datasheet summary, helping engineers sourcing, replacing, or re-spinning legacy MAX 7000S designs.

Applications typiques
EPM7128SLC84-6N convient pour 6 applications: ISA / Legacy Bus Address Decoding, Microcontroller I/O Expansion & Glue Logic, 5V Industrial Control & State Machines, Memory & Bus Interface Bridging, Legacy Peripheral Adapter Cards, Test & Measurement Front-End Logic.
ISA / Legacy Bus Address Decoding
The EPM7128SLC84-6N's 6 ns pin-to-pin delay and 68 user I/Os make it well suited to ISA-bus address decoding and chip-select generation in legacy industrial PCs. With 128 macro cells, designers can implement multi-bank decode windows and interrupt-acknowledge logic in a single device. Placed between the ISA bus connector and peripheral glue, it absorbs the random logic that would otherwise consume 6-10 discrete 74-series packages. Compared with discrete TTL, the CPLD reduces board area, simplifies timing closure, and allows in-system updates via JTAG without re-spinning the PCB when the address map changes.
Recommandé
Microcontroller I/O Expansion & Glue Logic
The EPM7128SLC84-6N absorbs peripheral glue around MCUs in 5V embedded systems, including LCD interface drivers, keypad scanners, PWM generators, and chip-select decoding. Its 68 user I/Os and 128 macro cells easily handle 4-6 peripheral interfaces in a single chip, eliminating 4-7 MSI packages. The EEPROM-based non-volatile configuration means instant-on behavior at power-up with no external boot memory, critical in real-time control applications. Compared with discrete logic, it offers deterministic timing, lower EMI, and field-upgrade capability via JTAG for firmware-revision changes without hardware rework.
Recommandé
5V Industrial Control & State Machines
The EPM7128SLC84-6N's 5V-tolerant I/Os and deterministic timing make it ideal for state-machine and protocol-conversion tasks in factory automation, motor-control boards, and process-control instrumentation. With 128 macro cells, it can implement complex Mealy/Moore state machines, encoder/decoder logic, and serial-protocol bridges (RS-422/485, SPI expansion) in a single chip. The 84-PLCC package is socket-friendly, simplifying field replacement and prototyping. Compared with microcontrollers for this role, the CPLD delivers sub-10 ns deterministic response without firmware overhead, ideal for hard-real-time control loops.
Recommandé
Memory & Bus Interface Bridging
The EPM7128SLC84-6N acts as a bridge between asynchronous bus domains (e.g., SRAM, flash, and legacy peripherals), absorbing wait-state generation, byte-lane steering, and parity logic. Its 6 ns pin-to-pin delay supports SRAM read/write cycles with minimal latency, while 68 user I/Os provide generous address and data routing. Compared with discrete bus drivers and latches, the CPLD reduces signal skew, simplifies PCB layout, and supports in-system reprogramming when the bus map changes. The MAX 7000S architecture's deterministic timing makes timing closure straightforward for multi-master shared-bus designs.
Recommandé
Legacy Peripheral Adapter Cards
The EPM7128SLC84-6N is widely used in legacy ISA/PCI add-in cards where it consolidates bus-interface logic, interrupt steering, and configuration registers into one programmable device. With 128 macro cells and 68 I/Os, designers can implement a complete custom I/O card with FIFO, DMA handshake, and register decode in a single 84-PLCC socketed part. The JTAG ISP interface allows card vendors to ship firmware updates without recall. Compared with discrete SSI/MSI glue, the CPLD simplifies EMC compliance by reducing chip count, loop area, and ground-bounce noise.
Recommandé
Test & Measurement Front-End Logic
The EPM7128SLC84-6N's 6 ns speed grade and 68 I/Os make it suitable for test-instrument front-end logic, including pattern generation, signal routing matrices, and trigger conditioning. Its deterministic 5V I/O can directly drive TTL-level instrumentation buses without level shifters. With 128 macro cells, designers can implement a 32-channel scan-multiplexer or a 16-bit parallel-data capture engine in one chip. Compared with discrete 74-series logic, the CPLD reduces BOM count, allows post-build configuration changes via JTAG, and supports instant-on operation required for production-test racks.

Principaux différenciateurs
- Fastest speed grade in the 84-PLCC MAX 7128 family (vs EPM7128SLC84-10)
- Lead-free (Pb-free) finish on the same 84-PLCC footprint (vs EPM7128SLC84-6)
- 68 user I/Os in a socketed 84-PLCC package (vs EPM7096LC84-15)
Notes de conception
The EPM7128SLC84-6N requires a stable 5V supply on both VCCINT (core) and VCCIO (I/O bank) pins, with multiple VCC/GND pins distributed around the 84-PLCC package to minimize internal ground-bounce. Decouple each VCC pin with a 0.1uF ceramic capacitor placed as close to the package as possible, and add a single bulk 10-47uF tantalum or aluminum-polymer capacitor near the supply entry. During in-system programming via JTAG, Icc may rise 20-40% above steady-state, so the regulator headroom should accommodate transient peaks without sagging below 4.75V.
For 84-PLCC layouts, place the device in a socketed footprint if field replacement is anticipated (typical for legacy industrial and test-instrument designs). Route JTAG signals (TDI, TMS, TCK, TDO) as a short daisy-chain with 10K pull-ups on TDI/TMS/TCK; place the JTAG header within 50mm of the device to avoid noise coupling. For high-speed signals (>50 MHz) crossing PLCC pin fields, use ground traces between signal pins and minimize via stubs on the package break-out layer.
Do not directly interface 3.3V CMOS logic to EPM7128SLC84-6N 5V I/O pins - the VIH minimum (3.5V typical) may not be reached reliably by 3.3V outputs, and 5V input levels exceed the absolute-maximum ratings of 3.3V-only devices when driven in reverse. Use a level shifter (74LVC245, TXS0108E, or discrete MOSFET circuit) for mixed-voltage designs. Also note that the device is in last-time-buy status as of 2026 - new designs should target MAX II (EPM240) or MAX V (5M40ZE64) equivalents, which offer 3.3V/2.5V tolerant I/Os in smaller packages.
Estimated: At maximum toggle activity (all 68 I/Os switching at 100 MHz, 5V supply, worst-case 25 pF loads), the EPM7128SLC84-6N 84-PLCC dissipates approximately 1.2W steady-state. The PLCC package has theta_JA of ~40 C/W in still air, yielding a 48C junction rise above ambient at full activity. For enclosed industrial enclosures with limited airflow, derate activity or attach a small clip-on heatsink. Most glue-logic designs run at 5-15 MHz with 20-30 active I/Os, keeping dissipation well below 0.5W - no heatsink is required in typical use.
Informations de conformité
Per Arrow product page, the part is reported EU RoHS compliant in some listings but the legacy 5V MAX 7000S family is generally not Pb-free across all variants; the 'N' suffix indicates lead-free solder-ball/finish composition. AEC-Q100 not applicable (industrial/commercial logic IC, not automotive-qualified).
