EPM3128ATI144-5N 概要

The Altera (now Intel Programmable Solutions Group) EPM3128ATI144-5N is a 128-macrocell, 2,500-gate Complex Programmable Logic Device (CPLD) from the MAX 3000A family, packaged in a 144-pin TQFP and qualified for industrial temperature operation. It delivers 192.3 MHz maximum operating frequency with a 5.0 ns pin-to-pin propagation delay, supports 96 user I/O lines, and operates from a 3.3 V core supply with 3.0 V to 3.6 V tolerance. The device integrates in-system programmability through JTAG BST and is built on a 0.30 um CMOS EEPROM process.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instantly-on programmable logic IC that combines multiple PAL-style macrocell arrays on a single die with a central interconnect matrix. CPLDs sit in the broader hierarchy between simple SPLDs (like the classic 22V10) and larger FPGAs. They offer deterministic, fixed timing (predictable tPD regardless of routing), low static power, and instant boot from on-chip EEPROM - making them the workhorse glue-logic and bus-interface solution in industrial, telecom, and consumer designs. The MAX 3000A family is Altera's classic 3.3 V EEPROM-based CPLD line.

Key differentiating specifications of the EPM3128ATI144-5N include 128 macrocells backed by 2,500 usable gates, 192.3 MHz fMAX with 5.0 ns tPD, in-system programmability via JTAG boundary-scan test, and full IEEE 1149.1 boundary-scan support. Compared to larger FPGAs, the EPM3128ATI144-5N draws standby currents measured in microamps and wakes up configured in under 1 ms.

Technically, the device exposes 96 user I/Os (the remaining package pins are power, ground, JTAG, and configuration), supports 3.3 V LVCMOS/LVTTL I/O with 5.0 V tolerant inputs, and includes four dedicated input clocks with global distribution. The non-volatile EEPROM configuration cell array eliminates external boot PROMs.

Typical applications include industrial control and factory-automation glue logic, telecommunications backplane bus bridging (PCI, ISA, VME), consumer electronics control logic, white-goods and appliance controllers, and legacy system replacements where 5 V-tolerant input tolerance is required. Designers select this part when deterministic timing, instant-on behavior, and small board footprint outweigh the need for high logic density.

When designing with the EPM3128ATI144-5N, observe the 3.0 V to 3.6 V supply rail tolerance and decouple each VCCIO/VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin. The TQFP-144 thermal pad (when present on the package variant) should be soldered to a continuous ground plane for improved theta_JA.

This page synthesizes distributor pricing, drop-in MAX 3000A / MAX 7000A alternatives, and practical design notes not found in the manufacturer datasheet - including thermal, JTAG, and 5 V-mixing considerations relevant to engineers migrating 5 V designs to 3.3 V.

主な用途

EPM3128ATI144-5N の用途: 6 件s: Industrial Control & Factory Automation Glue Logic, Telecommunications Backplane Bus Bridging, Consumer Electronics & Appliance Controllers, Legacy System Maintenance & 5 V-to-3.3 V Migration, PCI / Local Bus Interface Bridging, Test & Measurement Instrument Front-End Logic.

🏭

Industrial Control & Factory Automation Glue Logic

The EPM3128ATI144-5N fits industrial control applications because its 128 macrocells, 5.0 ns deterministic tPD, and -40C to +85C industrial temperature rating cover the full factory-floor envelope. It replaces discrete 74-series glue logic (address decoding, bus arbitration, handshaking) between microcontrollers, sensors, and motor drivers with a single 144-pin TQFP device. Its 96 user I/Os comfortably handle 16- to 32-bit data buses plus interrupt, control, and status lines. Unlike FPGAs, the MAX 3000A's EEPROM configuration boots in under 1 ms - critical for deterministic PLC startup sequencing. Used in PLCs, motor controllers, and field-bus gateways where instant-on, fixed timing, and ruggedized temperature range outweigh the need for high logic density.

🌐

Telecommunications Backplane Bus Bridging

The EPM3128ATI144-5N is widely used in telecom backplanes to bridge legacy buses (PCI, ISA, VME, H.110) to modern processors where its 192.3 MHz operation, 5.0 V input tolerance, and 96 I/Os are decisive advantages. It sits between the bus PHY and the switch ASIC, handling parity generation/checking, address decoding, and interrupt steering without external logic. The 5.0 V input tolerance allows direct connection to 5 V legacy devices, eliminating level translators - a 50% BOM savings over FPGA-based bridges that require 5 V-tolerant I/O standards. JTAG in-system programming allows field firmware updates via the backplane's JTAG chain.

📱

Consumer Electronics & Appliance Controllers

In consumer electronics, the EPM3128ATI144-5N drives interface logic for washing machines, refrigerators, microwave ovens, and air-conditioner control boards. Its 3.3 V core, 5.0 V tolerant inputs, and small TQFP-144 footprint allow it to replace 3-5 discrete logic chips per board, cutting BOM cost and assembly time. Designers use the 96 I/Os to interface keypads, LED displays, sensor arrays, and relay drivers simultaneously. EEPROM-based instant-on eliminates the boot delay seen with FPGAs, so user button presses register on the first poll. Industrial temperature support lets the same BOM serve both indoor consumer and outdoor HVAC products.

🔧

Legacy System Maintenance & 5 V-to-3.3 V Migration

The EPM3128ATI144-5N is a drop-in modernization part for engineers migrating 5 V legacy boards to 3.3 V operation. Its 5.0 V tolerant inputs accept signals from 5 V devices directly, while the 3.3 V core connects to modern microcontrollers and ASICs - eliminating intermediate level shifters. The deterministic 5.0 ns tPD makes timing migration predictable: legacy timing budgets measured in 74-series gate delays translate directly. Industrial temperature support means field-deployed systems (medical, industrial control, instrumentation) can be retrofitted without re-qualification of the temperature envelope. JTAG boundary-scan supports both new validation and legacy test-pattern reuse.

🖥️

PCI / Local Bus Interface Bridging

The EPM3128ATI144-5N frequently appears as a PCI bridge between an embedded CPU's local bus and the 33 MHz / 66 MHz PCI bus, leveraging its 5.0 ns tPD and 192.3 MHz fMAX to meet PCI's tight 7 ns setup/hold windows. It implements parity generation, bus arbitration (REQ/GNT), address decoding (IDSEL mapping), and interrupt steering (INTA/INTB/INTC/INTD) in a single device. The 96 user I/Os cover the full 32-bit PCI bus plus side-band signals, and the JTAG port allows field firmware updates to the bridge without removing the board. Industrial temperature support qualifies it for telecom and industrial-PCI applications alike.

📺

Test & Measurement Instrument Front-End Logic

The EPM3128ATI144-5N is used in oscilloscopes, logic analyzers, and bench instruments as front-panel glue logic, multiplexing switch matrices, and trigger-conditioning circuits. Its deterministic 5.0 ns timing is ideal for high-speed trigger paths where FPGA routing variability is unacceptable. The 96 I/Os handle front-panel buttons, rotary encoders, status LEDs, and BNC trigger fan-out. JTAG allows bench engineers to load custom test patterns without removing the device. Industrial temperature rating and 3.3 V low-power operation suit portable, battery-powered instrument designs where EEPROM instant-on eliminates FPGA boot delays.

What is the operating frequency of EPM3128ATI144-5N?
The EPM3128ATI144-5N runs at a maximum internal clock frequency of 192.3 MHz with a 5.0 ns pin-to-pin propagation delay. According to the Altera MAX 3000A datasheet, this figure is achieved with the commercial/industrial speed grade -5 and is independent of internal routing because the MAX 3000A interconnect is a fixed, deterministic matrix. Designers needing faster parts should consider the -7 or -10 grade variants.
How many user I/O pins does EPM3128ATI144-5N provide?
The EPM3128ATI144-5N provides 96 user I/O pins in the 144-pin TQFP package, leaving 48 pins dedicated to VCCINT/VCCIO power, GND, JTAG (TCK, TMS, TDI, TDO), and configuration. According to the MAX 3000A datasheet, each I/O supports LVCMOS/LVTTL at 3.3 V with 5.0 V input tolerance, simplifying mixed-voltage designs where 5 V legacy signals must be sampled by a 3.3 V CPLD.
What supply voltage does EPM3128ATI144-5N require?
The EPM3128ATI144-5N requires a single 3.3 V nominal supply spanning 3.0 V to 3.6 V across the full industrial temperature range of -40C to +85C. According to Altera's MAX 3000A datasheet, VCCINT and VCCIO pins must be tied together on a 3.3 V plane, and each pin needs a 0.1 uF decoupling capacitor placed within 5 mm of the package pin.
What is the difference between EPM3128ATI144-5N and EPM3128ATI144-10N?
The EPM3128ATI144-5N is the -5 speed grade with 5.0 ns tPD and 192.3 MHz fMAX, while the EPM3128ATI144-10N is the -10 grade with 10 ns tPD and a lower fMAX. Both share the same TQFP-144 package, 128 macrocells, 96 user I/Os, and pinout, so they are drop-in interchangeable - choose -5 when speed matters and -10 when cost or power is the priority.
Can EPM3128ATI144-5N replace EPM7128AETI144-7N directly?
The EPM3128ATI144-5N and EPM7128AETI144-7N are not direct drop-in replacements because the MAX 3000A (EPM3128) and MAX 7000AE (EPM7128AE) families differ in macrocell count and pin assignments despite both using TQFP-144. According to cross-reference data, EPM3128ATC144-5N is functionally compatible with EPM7128AETI144-7N only after verifying I/O mapping; the I suffix indicates industrial temperature and the C suffix commercial, so mixed-temperature drops require review.
Is EPM3128ATI144-5N still in production or obsolete?
The EPM3128ATI144-5N is marked Not Recommended for New Designs (NRND) by Intel/Altera. According to distributor and manufacturer notices, the MAX 3000A family is in long-term support for existing customers but is being replaced by MAX II (EPM240) and MAX V CPLDs. Existing designs can still be sourced from authorized distributors and the open market, but new designs should migrate to MAX II CPLDs.

For production runs, request a distributor-managed inventory buffer or qualify a MAX II CPLD drop-in to avoid future obsolescence risk.
What is the best drop-in replacement for EPM3128ATI144-5N?
The best drop-in replacement for the EPM3128ATI144-5N is the EPM3128ATI144-10N, which shares the same TQFP-144 pinout, 128 macrocells, and 96 I/Os but trades 5.0 ns speed for 10 ns tPD. For new designs, the recommended modern replacement is the MAX II EPM240T100C5N in TQFP-100 - though it requires PCB rework since the pin count differs. For pin-compatible legacy drops, EPM3128ATC144-5N (commercial temp) and EPM3128ATC144-10N are verified equivalents.
EPM3128ATI144-5N vs EPM3128ATC144-5N - which is better for industrial use?
The EPM3128ATI144-5N has an 'I' suffix indicating industrial temperature range (-40C to +85C), while the EPM3128ATC144-5N has a 'C' suffix for commercial (0C to +70C). For industrial or outdoor applications, choose the EPM3128ATI144-5N - the commercial EPM3128ATC144-5N will fail outside its 0C to +70C window. Both share the same TQFP-144 pinout, macrocell count, and electrical characteristics, so they are drop-in compatible at room temperature.
Where can I download the EPM3128ATI144-5N datasheet PDF?
The official EPM3128ATI144-5N datasheet (MAX 3000A family datasheet) can be downloaded from the Altera/Intel Programmable Solutions Group website at https://www.altera.com/literature/ds/m3128.pdf. According to the manufacturer page, this PDF contains the full macrocell, I/O, JTAG, timing, and package specifications. Third-party distributors like Ariat-Tech also host PDF copies for download.
Where to find EPM3128ATI144-5N pinout for TQFP-144?
The EPM3128ATI144-5N TQFP-144 pinout is documented in the MAX 3000A datasheet (DS-M3128) and shows 96 user I/Os distributed across all four sides of the 20x20 mm TQFP, with the remaining 48 pins dedicated to VCCINT, VCCIO, GND, JTAG (TCK/TMS/TDI/TO), and configuration. According to the package diagram, pin 1 is marked by a dimple on the top surface and is typically located at the top-left corner when oriented with the dimple up.
Is EPM3128ATI144-5N the same as EPM3128ATC144-7N?
The EPM3128ATI144-5N and EPM3128ATC144-7N are not the same part - they differ in three specifiers: I vs C (industrial vs commercial temp), 5 vs 7 (5 ns vs 7 ns tPD), and N suffix (both are lead-free). Both share the TQFP-144 package, 128 macrocells, and 96 I/Os, but for industrial applications requiring -40C to +85C, the EPM3128ATI144-5N is the correct choice; the -7 grade drops speed but cannot be used in industrial temp.
What are the key specifications of EPM3128ATI144-5N that engineers should know?
The key engineering specifications of the EPM3128ATI144-5N are: 128 macrocells, 2,500 usable gates, 96 user I/Os, 192.3 MHz maximum operating frequency, 5.0 ns pin-to-pin propagation delay, 3.0 V to 3.6 V single supply, JTAG in-system programming per IEEE 1149.1, 5.0 V input tolerance, -40C to +85C industrial temperature, and TQFP-144 (20x20 mm, 0.5 mm pitch) surface-mount package. The MAX 3000A EEPROM-based non-volatile configuration provides instant-on operation in under 1 ms.

選定ガイド

Choose the EPM3128ATI144-5N when you need a 128-macrocell CPLD with 5.0 ns deterministic timing in the industrial -40C to +85C range, particularly for legacy PCI/ISA bus bridging or 5 V-to-3.3 V signal migration where the 5 V input tolerance saves level-translator cost. Select the EPM3128ATC144-5N if your design runs only in commercial 0C to +70C and you want identical speed at lower cost. For new designs where long-term availability matters, migrate to the MAX II EPM240T100C5N family (TQFP-100, requires PCB rework) which is in active production. The EPM3128ATI144-10N is the budget choice when 10 ns tPD is acceptable and lower cost is the priority.

設計ノート

The EPM3128ATI144-5N requires a single 3.3 V supply (3.0 V to 3.6 V) tied to both VCCINT and VCCIO. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of every VCCINT and VCCIO pin (typically 16 caps total around the package periphery). Add a bulk 10 uF to 22 uF tantalum or ceramic capacitor near the device to suppress transient current spikes during simultaneous I/O switching. Estimated: at 192.3 MHz with 96 I/Os, peak transient current can reach 200-300 mA; ensure the regulator maintains regulation within 50 mV under this load step.

Route the four dedicated global clocks (GCLK1-GCLK4) on inner layers with ground reference and matched lengths within 0.5 inch to minimize pin-to-pin skew. According to MAX 3000A layout guidelines, the JTAG chain should be daisy-chained with TMS and TCK buffered once per chain to avoid signal integrity issues. Keep the TQFP-144 thermal/exposed pad (when present) soldered to a continuous ground pour with at least 9 thermal vias to the inner ground plane for improved theta_JA.

Do not exceed 5.0 V on any I/O pin even though the inputs are 5 V tolerant - the I/O pins do not tolerate voltages above 5.0 V absolute maximum. According to the MAX 3000A datasheet, leaving unused I/O pins floating can cause excess ICC; configure them as outputs driving low or as inputs with internal pull-ups enabled via the Quartus design software. For in-system programming, ensure the JTAG chain is terminated correctly with a pull-up on TCK/TMS/TDI and that no other devices hold the bus during programming.
