EPM7128SLC84-6N 개요
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.

일반적인 애플리케이션
EPM7128SLC84-6N 적합 용도: 6 애플리케이션s: 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.

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.
추천
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.
추천
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.
추천
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.
추천
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.

주요 차별점
- 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)
설계 노트
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.
규정 준수 정보
