EPM3064ALC44-7N 概述
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the broader taxonomy of digital semiconductors: programmable logic -> logic IC -> integrated circuit. CPLDs combine multiple PAL-like macrocell blocks on a single die with a programmable interconnect matrix, providing deterministic timing, instant-on operation (no external boot PROM required), and in-system programmability (ISP). The MAX 3000A family uses EEPROM configuration cells, so the device retains its logic pattern indefinitely without external memory and supports the IEEE Std 1149.1 JTAG interface for boundary-scan testing and ISP.
Key features of the EPM3064ALC44-7N include 1,250 usable gates, 64 macrocells distributed across 2 Logic Array Blocks (LABs), 34 user I/O pins, a maximum toggle frequency around 135 MHz (per family characterization), and a 3.3 V core supply with 5 V-tolerant I/O. The 7.5 ns tPD makes it suitable for glue-logic, interface bridging, and asynchronous state-machine replacement of discrete 74-series TTL/MSI parts. Each macrocell contains a programmable AND/OR array, a flip-flop with selectable clock/enable, and a tri-state output buffer with individually programmable pin functions.
Typical applications include bus decoding and address mapping in legacy microcontroller or 8051 systems, I/O expansion and signal conditioning for industrial controllers, replacement of multiple discrete SSI/MSI logic gates (74xx/54xx), power-on sequencing logic, and glue logic between ASICs and standard peripherals. The 44-PLCC footprint is socket-friendly for prototype and production rework.
Design with the EPM3064ALC44-7N by writing HDL in the Quartus II/Quartus Prime design suite (legacy MAX+PLUS II is also supported), then programming through the JTAG chain with a ByteBlaster, USB-Blaster, or compatible download cable. Note that the MAX 3000A family is mature and is recommended for new designs only when long-term availability and pin-compatibility with legacy designs matter more than latest-generation features.
This page synthesizes distributor pricing, drop-in alternatives drawn from the same MAX 3000A family, and practical design notes not found in the original datasheet.

典型应用
EPM3064ALC44-7N 适用于 6 应用s: Microcontroller Bus Decoding and Address Mapping, Discrete TTL/MSI Logic Replacement, Industrial I/O Expansion and Signal Conditioning, Power-On Sequencing and Reset Logic, ASIC/FPGA Glue Logic and Interface Bridging, Legacy Peripheral and Memory Controller Replacement.
Microcontroller Bus Decoding and Address Mapping
The EPM3064ALC44-7N's 64 macrocells and 34 user I/O pins make it well suited to decode multiplexed address and data buses in 8051, 68HC11, or ARM7 legacy systems. Its 7.5 ns pin-to-pin delay matches typical HC-series TTL decoder propagation, so chip-select signals are generated with deterministic timing. Unlike a discrete 74HC138/74HC139 decoder tree, the CPLD can implement priority decoding, address-range comparison, and wait-state generation in a single device, saving PCB area. The 3.3 V core with 5 V-tolerant I/O allows direct connection to 5 V microcontroller buses without level shifters.
推荐
Discrete TTL/MSI Logic Replacement
The EPM3064ALC44-7N can replace up to 20-30 discrete 74xx/54xx SSI/MSI logic packages (gates, decoders, multiplexers, flip-flops, counters) with a single programmable device, dramatically reducing PCB area and BOM cost in industrial controllers. Each macrocell implements AND/OR logic with a flip-flop, and the 7.5 ns tPD rivals HC-series TTL propagation delay. Designs migrate by re-targeting the original TTL schematic into the CPLD's development tool. The 44-pin PLCC socket-compatible package allows easy insertion into legacy boards originally designed for discrete logic.
推荐
Industrial I/O Expansion and Signal Conditioning
In factory automation and PLC I/O modules, the EPM3064ALC44-7N provides 34 user I/O pins that can be configured as inputs, outputs, or bidirectional, enabling expansion of a microcontroller's GPIO count or implementing optocoupler-isolated input conditioning. Its 5 V-tolerant I/O tolerates industrial 24 V signals when divided down with external resistor networks, and the JTAG interface allows in-system reprogramming for field firmware updates. The commercial 0C to +70C range covers most indoor industrial cabinet environments.
推荐
Power-On Sequencing and Reset Logic
The EPM3064ALC44-7N's instant-on EEPROM-based configuration makes it ideal for power-on sequencing logic in multi-rail systems, where discrete RC delay networks are inaccurate across temperature. Designers implement timing chains, watchdog timers, and rail-good combinators in a single CPLD with deterministic behavior from the first clock cycle after power-up. The 3.3 V core operates from common 3.3 V system rails, and the JTAG interface allows field reconfiguration if sequencing requirements change. This application typically uses only 10-20 macrocells, leaving room for additional glue logic.
推荐
ASIC/FPGA Glue Logic and Interface Bridging
When integrating ASICs or older-generation FPGAs with mismatched bus widths or voltage levels, the EPM3064ALC44-7N provides deterministic, low-latency glue logic that pure software drivers cannot match. With 7.5 ns tPD, it bridges timing-critical handshake signals between processors and peripherals, and its 5 V-tolerant I/O directly interfaces 5 V legacy peripherals from a 3.3 V core. Typical use cases include bus-width conversion (8-to-16 or 16-to-32 bit), FIFO flag generation, and interrupt prioritization. The 44-PLCC footprint is small enough for placement adjacent to the ASIC.
推荐
Legacy Peripheral and Memory Controller Replacement
The EPM3064ALC44-7N can replace obsolete peripheral controllers, memory interface logic, or EOL ASICs in long-lifecycle products where re-spinning the PCB is impractical. Its non-volatile EEPROM configuration retains the design indefinitely without an external boot PROM, and the same PLCC-44 footprint fits into legacy sockets designed for the original IC. Combined with the JTAG ISP interface, field upgrades can update logic patterns without removing the chip. This application is especially valuable in medical, aerospace, and industrial products with 15-20 year lifecycles.

关键差异点
- 7.5 ns speed grade balances cost and timing margin （对比 EPM3064ALC44-10N)
- 64 macrocells vs 32 in the EPM3032 family （对比 EPM3032ALC44-7N)
- Same PLCC-44 footprint as MAX 3032A for design reuse （对比 MAX II EPM240T100C5N)
设计说明
Estimated: at maximum toggle frequency with all 34 I/O pins switching at 5 pF load, the EPM3064ALC44-7N core current draw is approximately 50-80 mA from the 3.3 V supply, per typical MAX 3000A family characterization. Decouple VCC (pin 42) with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 uF tantalum near the supply trace. The PLCC-44 socket adds approximately 1-2 nH of inductance per pin; for high-speed designs (>100 MHz) consider soldering the PLCC directly rather than using a socket.
Do not confuse the EPM3064ALC44-7N with the EPM3064ATC44-7N - both are valid MAX 3064A parts in 44-PLCC but differ in operating temperature grade. The 'L' suffix denotes commercial 0C to +70C, while 'T' is also commercial but indicates a slightly different thermal characterization in legacy Altera datasheets. Industrial temperature grade is the EPM3064ALI44 variant (-40C to +85C). When migrating designs, always verify the temperature grade matches your environment. Also note that the JTAG chain shares pins with user I/O on certain configurations - consult the dedicated-pin tables in the datasheet before assigning user I/O to JTAG pins.
Place the EPM3064ALC44-7N JTAG header (TDI/TDO/TMS/TCK) at the board edge for easy access with a USB-Blaster or ByteBlaster download cable. Keep JTAG traces short (under 50 mm) and add 10 kohm pull-ups on TMS and TCK to prevent spurious JTAG state transitions during power-up. For multi-device JTAG chains, buffer TCK with a 74HC244 if the chain exceeds 4 devices. The unused I/O pins should be configured as outputs driving low (or inputs with internal pull-ups enabled) in the Quartus design to minimize quiescent current.
合规信息
RoHS/REACH/lead-free status for EPM3064ALC44-7N not explicitly stated in the verified data; consult Intel/Altera product declaration documents for definitive compliance information. The MAX 3000A family was originally released in the early 2000s, so some variants may be lead-containing; the '-7N' suffix typically indicates lead-free but should be confirmed with the manufacturer's full material declaration (FMD).
