EPM3064ATI44-10N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays on a single chip with a programmable interconnect fabric. CPLDs sit in the broader taxonomy of programmable logic devices (PLDs), alongside FPGAs. Compared to FPGAs, CPLDs typically offer lower logic density, deterministic timing (no routing delays), instant-on non-volatile configuration, and a simpler development flow - making them ideal for glue logic, bus interfacing, and control state machines rather than high-density data-path processing.
Key features include 64 macrocells, 34 user I/Os, four dedicated inputs, and a MultiVolt I/O architecture. The MAX 3000A architecture is built on CMOS EEPROM technology, providing non-volatile storage of the configuration bitstream so the device requires no external boot PROM and powers up instantly. Built-in boundary-scan (JTAG) test circuitry is included for board-level testability.
Typical applications include bus decoding and address mapping, power-up sequencing for multi-rail systems, I/O expansion via I2C/SPI-to-parallel bridges, glue logic between microcontrollers and peripherals, and state-machine-based control logic in industrial, telecom, and consumer designs. The combination of 3.3 V ISP, JTAG support, and instant-on operation also makes the EPM3064ATI44-10N well-suited to legacy board redesigns where pin-compatible drop-in replacements are required for obsolete CPLDs.
When designing with the EPM3064ATI44-10N, route the JTAG TMS, TCK, TDI, and TDO lines with proper termination and avoid stubs to maintain signal integrity for ISP. The four dedicated input pins are useful for global clock or asynchronous clear distribution across all macrocells without consuming user I/O resources.

Applications typiques
EPM3064ATI44-10N convient pour 6 applications: Bus Decoding and Address Mapping, Power-Up Sequencing for Multi-Rail Systems, I/O Expansion via I2C/SPI-to-Parallel Bridges, Glue Logic Between MCU and Peripherals, State-Machine-Based Control Logic, Legacy Board Redesign and Obsolescence Management.
Bus Decoding and Address Mapping
The EPM3064ATI44-10N is widely used as a bus decoder and address mapper between microprocessors, DSPs, FPGAs, and peripheral chips. Its 64 macrocells easily hold multi-output decode logic for chip-select generation, address-line demultiplexing, and interrupt prioritization. The 10 ns pin-to-pin delay and 100 MHz fMAX accommodate synchronous buses such as 33 MHz PCI and standard memory interfaces. Compared to discrete 74-series glue logic, a single EPM3064ATI44-10N replaces dozens of gates while remaining in-system programmable via JTAG.
Recommandé
Power-Up Sequencing for Multi-Rail Systems
The EPM3064ATI44-10N is a natural fit for power-supply sequencing controllers in multi-rail designs. Its non-volatile EEPROM configuration means it powers up instantly to a known state, releasing enable signals to downstream DC-DC converters in a deterministic order. With 34 user I/Os, the device can sequence up to 8-10 separate rails and monitor PGOOD flags. The industrial -40C to +85C range allows placement near hot power stages.
Recommandé
I/O Expansion via I2C/SPI-to-Parallel Bridges
Designers use the EPM3064ATI44-10N as an I/O expander when a microcontroller lacks sufficient GPIO. A small state machine inside the CPLD converts I2C or SPI commands from the MCU into parallel outputs, turning 2-4 MCU pins into 34 controlled outputs. The 10 ns delay supports SPI clocks up to ~50 MHz, and JTAG ISP allows in-field firmware updates without removing the part. This is common in industrial control boards and LCD/LED driver interfaces.
Recommandé
Glue Logic Between MCU and Peripherals
The EPM3064ATI44-10N consolidates discrete 74HC/74LVC glue logic in mixed-voltage designs. Its MultiVolt I/O allows direct interfacing between a 3.3 V MCU and 2.5 V peripherals without level shifters. Typical use cases include display timing generation for TFT panels, FIFO flag combining for memory interfaces, and PWM generation for motor pre-drive. The 44-pin TQFP package is compact enough for handheld and embedded designs.
Recommandé
State-Machine-Based Control Logic
The EPM3064ATI44-10N excels at implementing complex finite state machines for industrial and automotive control. The 64 macrocells comfortably fit FSMs with 16-24 states plus output decoding, and the deterministic 10 ns timing avoids the metastability and jitter concerns of FPGA-implemented state machines. Designers in motor control, solenoid drivers, and instrumentation frequently use it as the supervisory controller paired with a microcontroller.
Recommandé
Legacy Board Redesign and Obsolescence Management
Because the EPM3064ATI44-10N is marked obsolete, it is most commonly sourced today for legacy board redesigns and end-of-life support of installed industrial, telecom, and medical equipment. Engineers who need a pin-compatible drop-in for an aging CPLD on an existing PCB turn to the -7, -10, or low-power variants in the same MAX 3000A 44-pin TQFP family. The JTAG ISP interface allows reprogramming without desoldering, simplifying field firmware updates on legacy hardware.

Notes de conception
The EPM3064ATI44-10N requires a stable 3.3 V supply on VCCINT and either 3.3 V or 2.5 V on VCCIO. Decouple each VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin. The core supply ramp-up time should be slower than 1 ms to ensure clean JTAG ISP operation; if the ramp is too fast, the device may enter an indeterminate state. For battery-backed designs, consider the EPM3064ALI44-10N low-power variant which has substantially lower standby current.
Route the JTAG signals (TMS, TCK, TDI, TDO) as a daisy-chain with no stubs and a maximum trace length of 150 mm to preserve signal integrity at typical TCK frequencies of 10-25 MHz. Place a 10 kohm pull-up resistor on TMS and TDI per the JTAG specification to keep the bus in a benign state during power-up. The four dedicated input pins (GCLK1, GCLK2, OE1, OE2/GCLR) should be treated as high-fanout nets and routed with short, matched traces if used as global clocks.
Do not assume that the -7 and -10 speed grades are interchangeable without re-running static timing analysis - even though the die may be the same, factory speed binning means timing margins differ. Per the Altera community discussion thread, dual-marked -7 and -10 parts may exist on the same physical die, but always respect the marking on the package. Also note the EPM3064ATI44-10N is RoHS non-compliant per the digchip datasheet excerpt; for new designs targeting EU markets, select a RoHS-compliant MAX II alternative.
The 34 user I/O pins are organized into four I/O banks. Each bank shares a VCCIO supply, so all I/Os in a bank must use the same voltage. Mixing 3.3 V and 2.5 V signals requires careful bank assignment in the Quartus pin-planner. Output drive strength defaults to 8 mA at 3.3 V VCCIO, which is sufficient for short board traces; for longer traces or heavily loaded buses, enable the slow slew-rate and high-drive options in the device settings to control ringing.
Informations de conformité
Per the digchip datasheet excerpt, the EPM3064ATI44-10N is RoHS Non-Compliant and contains lead. AEC-Q100 is not applicable for this commercial/industrial-grade CPLD. REACH, halogen-free, and conflict-mineral status were not disclosed in the verified web data.
