Detailed Description

EPM7064TC44-7N is a MAX 7000 family CPLD from Altera (Intel), a non-volatile, in-system-programmable logic device designed for fast, deterministic control and glue logic. It offers around 64 macrocells with instant-on behavior and stable timing, ideal for implementing decoders, state machines, interface bridges, and wide fan-in logic where predictable timing matters. The -7 speed grade denotes a faster timing option. The TC44 suffix typically indicates a compact 44-pin thin quad flat package version. The “N” suffix is commonly used to denote a Pb-free, RoHS-compliant option. Please confirm exact electrical, mechanical, and environmental limits in the datasheet.

Key Features

Non-volatile CPLD fabric with instant-on behavior

In-System Programming via standard JTAG

Deterministic pin-to-pin timing, stable across voltage and temperature

Approx. 64 macrocells for medium-density control and glue logic

Familiar, mature tool support (e.g., Intel Quartus design flow)

Flexible I/O standard support for typical TTL/CMOS interfacing

Global clocks, product term-based architecture, efficient for control logic

Robust ESD and latch-up characteristics typical for mature CMOS CPLDs

Commercial temperature grade version available

RoHS-friendly option denoted by “N” in many Altera parts

Key Advantages

Instant-on and non-volatile configuration eliminates external boot memory

Predictable timing simplifies closure vs. SRAM FPGAs

Low static power compared with many FPGAs in small logic applications

Simple, fast updates via JTAG without removing the device

Cost-effective for glue logic, interface, and control tasks

Mature ecosystem and broad design-in history

Easier qualification in legacy systems that rely on CPLDs

Packaging

Type TC44 indicates a 44-lead thin quad flat package (TQFP), plastic molded

Material Plastic epoxy mold compound, Pb-free lead finish for RoHS compliance (typical for “N” option)

Size TQFP-44 body commonly around 10 mm x 10 mm with low profile; exact dimensions in datasheet

Pin configuration 44 pins total including user I/O, power, ground, and JTAG pins (TCK, TMS, TDI, TDO). I/O count depends on package routing; consult the pinout table in the datasheet for precise mapping

Thermal characteristics Typical TQFP junction-to-ambient values; depends on board, airflow, and copper area. Use datasheet and Intel PSG thermal guidance for accurate RθJA/RθJC

Electrical properties Supply voltage and I/O tolerance depend on subfamily variant. MAX 7000 devices commonly operate at 5 V or 3.3 V with compatible TTL/CMOS I/O. Speed grade -7 indicates faster timing. Confirm VIH/VIL, VOH/VOL, ICC, and timing parameters in the datasheet

Lifecycle

Status The MAX 7000 family is mature and, in many cases, limited for new designs. Availability can vary by speed grade, package, and regional inventory. It is not unusual for parts in this family to be NRND or approaching end of life

Recommended action For new designs, consider migration paths and verify long-term supply with Y-IC

Equivalent or alternative models Similar-capacity CPLDs and low-density programmable logic options you can evaluate

- Intel MAX V family (for example 5M40 or 5M80 devices depending on resource needs)

- Intel MAX II family (for example EPM240/EPM570 for control logic tasks)

- Xilinx CoolRunner-II XC2C64A series (64 macrocell class, various 44-pin packages)

- Lattice ispMACH 4000 family (for example M4A3-64/32 variants depending on package)

- Microchip (Microchip/Atmel) ATF15xx CPLD family for legacy 5 V and mixed-voltage logic

- Note Alternatives may not be drop-in. Pinout, voltage, timing, toolchains, and programming methods will differ. Y-IC can help you select and validate the best fit
