EPM3064ATC44-10NAF جائزہ

The Intel (Altera) EPM3064ATC44-10NAF is a 64-macrocell, 1250-gate CPLD from the MAX 3000A programmable logic family, featuring 34 user I/O pins and a 10 ns maximum pin-to-pin propagation delay, housed in a 44-pin TQFP (10x10 mm) package. It belongs to the non-volatile, in-system programmable (ISP) MAX 3000A family and operates from a single 3.0 V to 3.6 V supply. The "-10N" speed grade indicates 10 ns tPD while the "AF" suffix designates lead-free / NiPdAu lead finish for modern assembly lines.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocells on a single die, providing predictable timing, instant-on operation, and wide input-gluing capability. Within the broader taxonomy, CPLDs sit between simple SPLDs/PLDs and larger FPGAs, serving glue-logic, interface bridging, and power-up state-machine roles where deterministic timing and zero-boot-delay configuration are mandatory. The MAX 3000A family from Intel/Altera uses EEPROM-based configuration cells, so the device retains its logic image even after power removal without an external boot PROM.

Key features include 64 macrocells organized into 4 logic array blocks (LABs) of 16 macrocells each, 1250 usable gates, 34 I/O pins with multi-voltage I/O support, IEEE Std. 1149.1 JTAG boundary-scan test (BST) and IEEE Std. 1532 in-system programmability, and a 10 ns maximum propagation delay from input pin to output pin. The device also provides a global Clear signal, four pin-compatible I/O standards, and pin-locking capability that preserves the board layout across design iterations. Programmable interconnect uses the Altera Classic / MAX architecture with continuous routing that simplifies timing closure.

The EPM3064ATC44-10NAF is built on a 5 V-tolerant I/O structure with multi-voltage I/O capability for interfacing with 3.3 V, 2.5 V, and 1.8 V logic without external level shifters. Internal pull-up resistors on every I/O simplify board layout by eliminating external resistors on unused or tri-stated pins. The EEPROM configuration cell is rated for 100 erase/program cycles, suiting design-stage iteration and field upgrades via JTAG. The TQFP-44 (10x10 mm) package is a JEDEC-standard thin quad flat pack suitable for reflow soldering.

Typical applications include bus and peripheral interface bridging (e.g., address decoding between an MCU and SRAM), state-machine and control-logic replacement for 74LS/HC discrete glue, power-up sequencing logic for FPGAs and SoCs, and small bus-multiplexing/level-translation bridges. Designers choose MAX 3000A parts when they need instant-on, deterministic-timed logic without the cost or complexity of an SRAM-based FPGA. In cost-sensitive industrial controls and consumer electronics, the EPM3064A series is often the lowest-cost CPLD for sub-128 macrocell designs.

When designing with this device, plan a 100 nF decoupling capacitor adjacent to every VCCIO/VCCINT pair, keep JTAG TMS/TCK/TDO/TDI traces short and series-terminated, and configure unused I/O pins as outputs driving low or as inputs with internal weak pull-ups enabled. Confirm Quartus II MAX+PLUS II or legacy MAX+PLUS II compatibility, because the MAX 3000A family is supported by Altera/Intel MAX+PLUS II and Quartus II design software but is NOT supported by modern Quartus Prime Pro/Standard editions.
