EPM3064ATI44-7 Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a programmable interconnect matrix, sitting between small SPLDs and FPGAs in the programmable logic taxonomy. The MAX 3000A family uses EEPROM cells to store configuration, so the device retains its logic on power-up without an external boot PROM - a key advantage over SRAM-based FPGAs in cost-sensitive and instant-on applications such as bus interface glue logic, I/O expansion, and power-up sequencing state machines.
Key features include a 135.1 MHz internal fMAX, 3.3 V core operation, JTAG-based IEEE 1532 ISP, multi-volt I/O compatibility (the 'I' in TI44 denotes industrial temperature grade), and PCI SIG compliance for -4 through -10 speed grades per the MAX 3000A datasheet. The 44-TQFP footprint provides compact integration for board-constrained designs.
Architecturally, the EPM3064ATI44-7 is built on a 0.30 µm CMOS EEPROM process with four Logic Array Blocks (LABs) of 16 macrocells each, an enhanced interconnect switch matrix (the 'FastTrack' interconnect), and dedicated inputs plus I/O pins that can be configured per pin as input, output, or bidirectional. The 'A' suffix designates the MAX 3000A generation with improved ISP and lower power versus the legacy MAX 3000 family.
Typical applications include PCI bus interface glue logic, address decoding, power-up sequencing controllers, I/O expansion for microcontrollers without enough pins, and legacy system replacement where non-volatile, instant-on logic is required. Its 7.5 ns tPD comfortably meets 66 MHz PCI timing at 3.3 V.
When designing with the EPM3064ATI44-7, ensure the JTAG chain (TCK, TMS, TDI, TDO) is properly terminated with 4.7 kΩ pull-ups on TCK per IEEE 1149.1, and reserve the four JTAG pins dedicated to ISP - they cannot be used as general-purpose I/O even when JTAG is unused. Decouple VCCINT and VCCIO pins with 0.1 µF ceramic capacitors placed within 3 mm of the package.

Applications typiques
EPM3064ATI44-7 convient pour 6 applications: PCI Bus Interface Glue Logic, Power-Up Sequencing Controller, Microcontroller I/O Expansion, Address Decoding and Chip Select Logic, Legacy Industrial System Replacement, Bus Interface Bridge and Protocol Translation.
PCI Bus Interface Glue Logic
The EPM3064ATI44-7's 7.5 ns tPD and PCI SIG Rev. 2.2 compliance make it well-suited for PCI bus glue logic at 33 MHz, where address decoding, command decoding, and parity generation must complete within a single 30 ns PCI clock cycle. With 64 macrocells and 34 I/O, the device can implement multi-function decode, wait-state insertion, and bus arbitration state machines in a single chip. Place the CPLD between the PCI bus and the local microcontroller or ASIC, using VCCIO at 3.3 V to match the PCI signaling environment; unlike a small FPGA, the EEPROM-based configuration powers up instantly with no boot delay.
Recommandé
Power-Up Sequencing Controller
The EPM3064ATI44-7's non-volatile EEPROM configuration and 64 macrocells make it ideal for multi-rail power-up sequencing in industrial and telecom systems. The device can monitor PG (power-good) signals from up to 8-12 DC-DC converters and assert enable signals in a programmed order with configurable delays implemented in logic. Operating from 3.0-3.6 V, it can be powered from a standby rail and remain active while sequencing main rails. Compared to a discrete sequencing solution using timers and logic gates, the CPLD provides programmable timing, easy design changes via JTAG, and smaller board area in a 44-TQFP.
Recommandé
Microcontroller I/O Expansion
Designers using microcontrollers with insufficient GPIO often use the EPM3064ATI44-7 to add 34 user I/O lines from a single 3.3 V supply. The CPLD connects to the MCU via SPI or parallel bus, allowing up to 32 register-mapped I/O bits per device with logic-level translation done in the macrocell fabric. With 7.5 ns tPD and 135.1 MHz fMAX, the device can implement shift registers, PWM generators, or quadrature decoders in hardware, offloading the MCU. Industrial temperature grade (-40 to +85 °C) suits factory automation and outdoor equipment.
Recommandé
Address Decoding and Chip Select Logic
Memory and peripheral address decoding in 8/16/32-bit embedded systems is a classic CPLD use case where the EPM3064ATI44-7's 64 macrocells provide ample capacity for 8-16 chip-select outputs with full address-decode logic and minimal external glue. The 7.5 ns tPD easily fits within a 50 ns memory cycle, and the JTAG ISP lets engineers iterate the decode map without removing the chip. Industrial temperature rating suits harsh-environment embedded systems such as factory controllers, transportation, and outdoor telecom equipment.
Recommandé
Legacy Industrial System Replacement
The EPM3064ATI44-7 is a drop-in replacement for legacy 44-TQFP MAX 3000A designs where original parts have reached end-of-life and field-repair inventory is critical. With identical footprint, pinout, and Quartus II programming flow, the device can substitute for EPM3064ATC44-7, EPM3064ATI44-10, or other MAX 3000A -7/-10 speed grades with timing within datasheet margins. Use it to maintain production of long-lifecycle industrial controllers, medical instruments, and military systems where PC board redesign is cost-prohibitive and IEC compliance testing must not be repeated.
Recommandé
Bus Interface Bridge and Protocol Translation
The EPM3064ATI44-7 enables bridging between legacy parallel buses (ISA, PC/104, custom microcontrollers) and modern peripherals, with up to 34 I/O supporting 16-bit data plus 8-bit address plus control signals. The 7.5 ns tPD accommodates full-speed protocol translation at 50 MHz, and the EEPROM configuration preserves bridge logic across power cycles - critical for bus analyzers and protocol converters that must boot into a known state. Designers can use Quartus II schematic capture or VHDL/Verilog to implement bus-master arbitration, FIFO flag generation, or level-shifting state machines in a single device.

Notes de conception
Place 0.1 µF ceramic decoupling capacitors within 3 mm of each VCCINT (pin 18) and VCCIO (pin 40) supply pin. Add a 10 µF tantalum or ceramic bulk capacitor at the board-level 3.3 V plane near the CPLD. The four GND pins (10, 26, 35, plus one internal) must all be connected to a low-impedance ground plane for ISP reliability and signal-integrity - per MAX 3000A datasheet recommendation, use a continuous ground plane under the TQFP body with vias stitching every 5 mm.
Per IEEE 1149.1 JTAG specification, TCK requires a 4.7 kΩ pull-up to VCCIO and TMS/TDI require 4.7 kΩ pull-ups to VCCIO if the JTAG chain is not actively driven. The TDO output is open-drain on some Altera CPLDs and benefits from a 4.7 kΩ pull-up. Route JTAG signals away from high-frequency switching nets (clock, PCI bus edges) and keep the chain under 6 inches total to avoid signal-integrity failures during ISP.
The four JTAG pins (TCK, TMS, TDI, TDO) on the EPM3064ATI44-7 cannot be reused as general-purpose I/O even when JTAG is unused - they are dedicated per IEEE 1149.1. If JTAG is not needed in production, leave TCK grounded or pulled low at the connector to prevent floating-pin noise injection. Additionally, the 'N' suffix denotes Pb-free finish; if your assembly line is not Pb-free compliant, choose the non-N variant. Verified datasheet document number is referenced generically as the MAX 3000A family datasheet (no specific document number was provided in the verified data).
Informations de conformité
RoHS/REACH status for the EPM3064ATI44-7 (non-N suffix) was not provided in the verified web data; the 'N' suffixed variants (EPM3064ATI44-7N) are Pb-free per Altera ordering nomenclature. AEC-Q100 not applicable - this is a commercial/industrial-grade CPLD, not an automotive-qualified part. For automotive designs, choose automotive-qualified MAX V or MAX 10 variants.
