EPM3128ATI10010N Présentation
A Complex Programmable Logic Device (CPLD) is a non-volatile digital IC that integrates multiple PAL/GAL-style logic blocks on a single die, connected through a programmable interconnect matrix. Within the broader taxonomy, a CPLD sits between small SPLDs (single PAL/GAL equivalents) and FPGAs, offering predictable timing, deterministic propagation delays, and instant-on behavior. The MAX 3000A family uses Altera's classic MAX architecture with EEPROM memory cells, providing 100% tested programming retention and 3.3 V in-system programmability (ISP) via IEEE 1149.1 JTAG.
Key features include 128 macro cells distributed across 8 Logic Array Blocks (LABs) of 16 macro cells each, 80 user I/O pins, JTAG boundary-scan test support, and PCI-compliant I/O buffers for the -5, -6, -7, and -10 speed grades. The device supports multi-volt core operation from 3.0 V to 3.6 V and I/O bank voltages of 1.8 V, 2.5 V, or 3.3 V, allowing flexible mixed-voltage interfacing.
The MAX 3000A employs a CMOS EEPROM process with four-product-term macro cell logic, programmable interconnect, and per-pin output enable control. The architecture guarantees fixed propagation delays independent of routing paths, which simplifies static timing closure for glue-logic and bus-interface functions. Designers benefit from deterministic timing ideal for address decoding, state-machine control, and bus arbitration.
Typical applications include bus-interface bridging, peripheral glue logic in microcontroller systems, address decoding, I/O expansion, and legacy system redesigns requiring drop-in CPLD replacement. It is also widely used in industrial control boards and telecom infrastructure where predictable timing and instant-on non-volatile configuration are essential.
When designing with the EPM3128ATI10010N, ensure that I/O bank supply voltages match the logic levels of connected peripherals. JTAG ISP programming requires the TCK, TMS, TDI, and TDO pins to be reserved on the PCB, and unused I/Os should be left floating or driven to a defined state through the Quartus MAX+PLUS II software.

Applications typiques
EPM3128ATI10010N convient pour 6 applications: Bus Interface Bridging, Address Decoding and Chip-Select Generation, Industrial Control Glue Logic, Legacy System Redesign and Form-Fit Replacements, Telecom Backplane Glue Logic, I/O Expansion and Voltage-Level Translation.
Bus Interface Bridging
The EPM3128ATI10010N is well suited to bridge legacy 8-bit or 16-bit microcontroller buses to modern peripherals because its 80 user I/Os and 128 macro cells comfortably decode multiple chip-select windows simultaneously. With 10 ns pin-to-pin delay at -10 grade, the device meets typical 33 MHz PCI Local Bus timing while remaining deterministic regardless of routing paths. The 3.3 V core with 1.8 V/2.5 V/3.3 V multi-volt I/O banks allows direct connection to 1.8 V modern MCUs without external level shifters, simplifying mixed-voltage board designs and reducing BOM cost.

Address Decoding and Chip-Select Generation
With 128 macro cells organized into 8 LABs of 16 macro cells each, the EPM3128ATI10010N can decode wide address ranges for memory and peripheral chip-select generation in microprocessor systems. Its 10 ns propagation delay ensures clean, glitch-free select lines even at high system clock rates. The non-volatile EEPROM configuration eliminates boot-time configuration delays typical of SRAM-based FPGAs, enabling instant-on chip-select output at power-up. Industrial temperature grade (-40C to +85C) supports factory and outdoor embedded deployments.
Recommandé
Industrial Control Glue Logic
The EPM3128ATI10010N serves as the central glue-logic hub in industrial controllers, integrating I/O expander interfaces, watchdog timers, and protocol translation between PLC backplanes and sensor front-ends. Its 80 user I/Os handle multiple 24 V opto-isolated interfaces when paired with external level shifters. Deterministic timing simplifies safety-critical state-machine design where predictable response is mandatory. The JTAG IEEE 1149.1 ISP interface allows in-field firmware updates without removing the board from service.
Recommandé
Legacy System Redesign and Form-Fit Replacements
Designers maintaining long-lifecycle industrial and telecom equipment use the EPM3128ATI10010N to replace obsolete or damaged CPLDs without PCB rework. The TQFP-100 footprint is identical to EPM3128ATC100-10N, EPM3128ATC100-7N, and other MAX 3000A family members, enabling direct swap when temperature grade and speed grade match the original BOM. EEPROM-based non-volatile configuration preserves design IP across years of field operation. The 3.3 V core minimizes migration risk from 5 V legacy designs that already include 3.3 V rails.
Recommandé
Telecom Backplane Glue Logic
In telecom backplanes, the EPM3128ATI10010N provides hot-swap control, I2C/SPI management bus bridging, and clock-distribution fan-out with deterministic 10 ns latency. Its 80 user I/Os are sufficient to bridge multiple management buses and discrete status LEDs across line cards. PCI-compliance for grades -5/-6/-7/-10 enables direct interfacing to CompactPCI and AdvancedTCA backplanes. Industrial temperature grade supports outdoor cabinet deployment where ambient temperatures swing widely between -40C and +85C.
Recommandé
I/O Expansion and Voltage-Level Translation
The EPM3128ATI10010N's multi-volt I/O banks (1.8 V, 2.5 V, 3.3 V) make it an ideal bidirectional voltage translator between modern low-voltage processors and legacy 3.3 V peripherals. With 80 user I/Os distributed across four I/O banks, designers can dedicate each bank to a different voltage domain. The non-volatile EEPROM configuration eliminates the need for external boot ROM, simplifying multi-rail designs. Up to 128 macro cells allow individual direction-control logic per channel when used as a buffered level shifter.

Notes de conception
The EPM3128ATI10010N requires a stable 3.3 V core supply (VCCINT) decoupled with at least one 0.1 uF ceramic capacitor per VCCINT pin placed as close to the package as possible. The I/O bank supplies (VCCIO) can be tied to 1.8 V, 2.5 V, or 3.3 V independently to interface with mixed-voltage peripherals. Add a bulk 10 uF tantalum or ceramic capacitor near the device to suppress transient current spikes during simultaneous output switching across all 80 I/Os. Estimated: total quiescent current is approximately 10-15 mA in normal operation; verify with bench measurement.
Reserve JTAG pins TCK, TMS, TDI, TDO, and TRST on the PCB even if in-system programming is not initially used, because the same pins enable boundary-scan testing during manufacturing. Place decoupling capacitors within 100 mils of their respective supply pins. Keep high-speed I/O traces short and matched when using the device for bus-interface bridging; the 10 ns propagation delay leaves limited timing margin at 100 MHz. Exposed thermal pad is not present on TQFP-100, so no thermal pad soldering is required.
Do not confuse the 'I' suffix (industrial -40C to +85C) with the 'C' suffix (commercial 0C to +70C) when substituting variants - both share the TQFP-100 footprint, so swapping is electrically invisible until field failure. Always confirm device programming voltage compatibility when migrating between MAX 3000A speed grades. Do not connect VCCIO to 5 V; the absolute maximum is 3.6 V. When migrating from EPM3128A to MAX II EPM240T100, note that the JTAG pinout differs and PCB rework is required.
