Typical Applications
EPM3128ATI10010N is suitable for 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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.

- EEPROM non-volatile instant-on configuration (vs EPM240T100C5N (MAX II))
Design Notes
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.
Compliance Information
Compliance data not provided in verified web data; RoHS/REACH/lead-free status should be confirmed with the manufacturer (Intel FPGA/Altera) before industrial qualification. The CPLD is not an automotive-grade IC (AEC-Q100 not applicable).
