EPM7128SLC84-15N 개요
A CPLD is a user-programmable semiconductor that combines configurable logic blocks with nonvolatile configuration memory. In the broader hierarchy, a CPLD is a programmable logic device, a semiconductor, and a complement to FPGA and mask-programmed logic solutions. The MAX 7000 architecture provides deterministic timing and straightforward integration into designs that need programmable Boolean functions, address decoding, bus control, or legacy-interface logic.
Key verified features include 128 macrocells, 2.5K logic gates, 68 I/Os, 76.9 MHz operation, 5 V operation, and an 84-pin PLCC package. The LC suffix identifies the leaded-chip carrier package, while the -15 suffix identifies the 15 ns device speed grade. One distributor result describes the EPM7128SLC84-15 as functionally and pin-compatible with earlier EPM7128 variants in the same speed grade and package, making replacement selection primarily a matter of package, speed, electrical, and qualification verification.
The EPM7128SLC84-15N is suitable for industrial and legacy control logic where a 5 V supply, leaded PLCC package, and a moderate logic capacity are acceptable. Typical uses include industrial automation interfaces, peripheral controllers, signal conditioning, state machines, bus arbitration, and board-level control. It can also serve as a bridge between older microprocessors and newer digital subsystems when the required logic fits within 128 macrocells.
The primary design consideration is verifying timing, power, pinout, and programming compatibility against the system requirements. Because a CPLD replacement is not automatically safe merely because the family name matches, confirm the package pin count, pin assignments, I/O voltage, macrocell count, speed grade, and programming file support. The 84-pin PLCC footprint should not be treated as interchangeable with QFP, TQFP, or BGA packages.
This page consolidates verified source specifications, pricing references, cross-reference results, and practical replacement guidance. It also distinguishes the exact EPM7128SLC84-15N from the separately listed EPM7128SLC84-15 and explains when a substitute can be considered for legacy 5 V MAX 7000 designs.

일반적인 애플리케이션
EPM7128SLC84-15N 적합 용도: 6 애플리케이션s: Industrial Automation Control, Peripheral Bus Interface, Legacy Processor Glue Logic, Signal Decode and Routing, Board-Level State Machine, Instrumentation and Test Control.
Industrial Automation Control
The EPM7128SLC84-15N fits programmable industrial control logic where 128 macrocells and 68 I/Os are sufficient for sequencing, state-machine, and interface functions. Its stated 76.9 MHz operating frequency and 15 ns speed grade provide timing capability for control logic that is faster than simple relay or discrete implementations. The 5 V supply and 84-pin PLCC package suit legacy or brownfield industrial boards, but system temperature, isolation, and EMC requirements must be checked separately.
추천
Peripheral Bus Interface
Use the EPM7128SLC84-15N as a programmable interface controller between a microprocessor or microcontroller and discrete digital peripherals. The 128 macrocells can implement address decoding, bus arbitration, latch control, interrupt request logic, and level translation within the device's specified electrical limits. Its 68 I/Os provide substantial board-level connectivity, while the 15 ns speed grade helps preserve timing margin in synchronous control paths.
추천
Legacy Processor Glue Logic
The EPM7128SLC84-15N is suitable for legacy processor boards requiring programmable glue logic after a processor interface redesign. A CPLD can implement address decode, command sequencing, data steering, handshake generation, and status multiplexing without changing the original processor footprint. The 84-pin PLCC package enables replacement of an older leaded PLCC design only after confirming the PCB land pattern and pin assignment; the part is not compatible with every 84-pin package.
추천
Signal Decode and Routing
The device can implement programmable decode trees, signal routers, mux/demux logic, pulse stretchers, and control matrices in systems that fit within 128 macrocells. Its 76.9 MHz stated frequency makes it relevant for moderate-speed digital routing rather than high-speed serial or memory-interface applications. Designers should use the datasheet timing tables to verify every path and should not assume that the 15 ns suffix guarantees the same timing across all package and temperature options.
추천
Board-Level State Machine
For sequencing and protocol-control tasks, the EPM7128SLC84-15N can implement finite-state machines, command decoders, timers, and handshake logic in a single programmable IC. The 128 macrocells and 68 I/Os allow multiple board functions to be consolidated when the design remains within the device's stated capacity. Its PLCC package and 5 V operating supply are practical for legacy industrial and instrumentation boards, although modern production designs must verify lifecycle availability and tooling support.
추천
Instrumentation and Test Control
The EPM7128SLC84-15N can support programmable control and measurement-interface logic in older instrumentation systems, including relay control, status encoding, measurement sequencing, and operator-panel interfaces. Its 68 I/Os allow numerous external digital signals to be coordinated, while the 15 ns speed grade supports faster control transitions than a slow discrete implementation. Confirm analog-interface isolation, input thresholds, and environmental requirements separately because those specifications are not present in the supplied data.

설계 노트
Do not select a substitute from the EPM7128 family name alone. Confirm the exact package, pin-one location, PLCC lead pitch, I/O assignments, voltage, macrocell count, speed grade, temperature grade, and programming-file compatibility. The supplied search results explicitly list EPM7128SLC84-15 and EPM7160ELC84-15 as comparison references, but they do not provide enough verified data to declare either universally interchangeable.
Keep the 84-pin PLCC footprint and its solder pads centered in the same mechanical arrangement as the original board. Verify pin numbering against the manufacturer package drawing, especially because PLCC J-lead devices can be rotated or installed with incorrect orientation. Check pin 1, lead clearance, thermal and copper requirements, and the assembly process before releasing a replacement board.
Design the 5 V supply path for the CPLD's actual input, output, and I/O loading under the required operating state. The supplied data confirms 5 V operation but does not provide current-consumption values, so do not estimate the supply requirement from the 76.9 MHz frequency. Decouple the device according to the manufacturer datasheet and include margin for inrush, I/O load, and nearby logic.
The listed 66-page datasheet and 1 MB file size come from a third-party mirror, while the source set also includes an official Altera Corporation description. Use the manufacturer ordering information to resolve any conflict between the EPM7128SLC84-15 and EPM7128SLC84-15N suffix conventions. Do not rely on a distributor page alone for pinout, timing, or lifecycle decisions.
규정 준수 정보
The verified UTSource result states that EPM7128SLC84-15N is RoHS compliant. The supplied data does not establish REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status.
