EPM3064ATC100-4 Visão geral

The Altera EPM3064ATC100-4 is a 64-macrocell member of the MAX 3000A family of high-performance, low-cost, EEPROM-based Complex Programmable Logic Devices (CPLDs) housed in a 100-pin TQFP package. It delivers 4.5 ns pin-to-pin logic delays, 222.2 MHz (227.3 MHz counter) performance, and approximately 1,250 usable gates with 64 macro cells distributed across 2 Logic Array Blocks (LABs), plus 34 user I/O pins operating at 3.3 V.

A CPLD (Complex Programmable Logic Device) is a non-volatile, flash/EEPROM-backed programmable logic device that implements combinational and sequential logic using a sum-of-products architecture organized as macro cells. In the broader hierarchy, the CPLD sits between simple SPLDs/PLDs and FPGAs: it provides deterministic, ultra-fast pin-to-pin timing (often sub-5 ns), instant-on behavior, and high-drive I/O - making it the workhorse for glue logic, bus bridging, and power-up sequencing. The MAX 3000A family is Altera's classic 3.3 V CPLD line, with in-system programmability via IEEE 1149.1 JTAG.

Key features include 600-10,000 usable gates, in-system programmability (ISP) through the JTAG interface, MultiVolt I/O supporting 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfacing, and four dedicated input pins for high-speed control signals. The CMOS EEPROM process gives non-volatile configuration with zero standby power, and the TQFP-100 package supports surface-mount manufacturing with standard JEDEC reflow profiles.

The device is built on a 5-level Altera MAX architecture with each macro cell containing a programmable AND/OR array, a configurable flip-flop, and fast product-term steering. Programmable interconnect couples the LABs with predictable, deterministic timing - critical for replacing discrete 74LS/74HC glue logic, asynchronous bus bridges, and PWM/timer peripherals that PLLs and microcontrollers cannot easily handle.

Typical applications include bus decode and address latching in legacy x86/embedded systems, asynchronous SRAM/Flash glue logic, motor-control PWM and timer replacement, industrial PLC I/O expansion, and power-sequencing networks for multi-rail systems. Its instant-on behavior also suits hot-swap controllers, ISA-to-PCI bridges, and high-drive LED/relay scan matrices.

When designing with the EPM3064ATC100-4, allocate at least four pins as JTAG (TCK, TMS, TDI, TDO) plus one TRST, follow Altera's ByteBlaster pinout recommendations, and respect the 3.3 V VCCINT supply. Choose the -4 speed grade for 4.5 ns tPD; slower -7 and -10 grades are pin-compatible for cost-sensitive timing paths.
