EPM7128AETI144-10N Overview
A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic device that sits in the hierarchy between simple PLDs and FPGAs. It typically consists of multiple PAL-like macrocell logic array blocks (LABs) interconnected by a global programmable interconnect matrix (PIA), with on-chip EEPROM or flash configuration memory. CPLDs are chosen when designers need deterministic timing, fast input-to-output propagation, and the ability to retain configuration without an external boot memory.
The EPM7128AETI144-10N is built on a 0.35 µm CMOS EEPROM process and integrates four Logic Array Blocks (LABs) with 36 macrocells each, totaling 144 macrocells in the die. Each macrocell contains a programmable AND/OR array, a flip-flop, and dedicated product-term steering, which gives the device true single-chip, single-cycle operation with no external configuration PROM. The 10 ns tPD enables 125 MHz+ state-machine and interface-bridging clock rates, while the high-drive I/O cells support 5 V tolerant inputs on a 3.3 V VCCIO when configured for mixed-voltage systems.
Typical applications include bus interface bridging (PCI, ISA, VME), peripheral glue logic in microcontroller/DSP systems, address decoding, state-machine controllers, and high-speed data-path multiplexing. The wide I/O count and JTAG ISP make it well suited for production-line programmable designs that need field upgrades without a programmer socket.
When designing with this device, place the four global clock/clear pins on low-skew dedicated traces and follow Altera's TQFP-144 land-pattern recommendations. The EPM7128AETI144-10N is one member of the MAX 7000A family; selecting -7, -10, -12, or -15 speed grades trades off tPD against Icc.

Typical Applications
EPM7128AETI144-10N is suitable for 6 applications: PCI/ISA Bus Interface Bridging, Microcontroller/DSP Glue Logic, Address Decoding & Memory Mapping, Industrial Control State Machines, Communication Protocol Bridging, Legacy Peripheral Expansion Boards.
PCI/ISA Bus Interface Bridging
The EPM7128AETI144-10N fits PCI/ISA bus bridging because its 128 macrocells and 100 user I/O pins can implement address latches, data buffers, and command decoders for legacy peripheral expansion. With a 10 ns tPD, the device meets the 33 MHz PCI clock-to-output budget with comfortable margin, while 5 V tolerant inputs on 3.3 V VCCIO allow direct interfacing to 5 V ISA slots. The on-chip EEPROM eliminates boot ROMs and reduces board area. Companion devices include the Altera MAX 7000A family members with larger I/O counts for fan-out.
Recommended
Microcontroller/DSP Glue Logic
The EPM7128AETI144-10N provides deterministic glue logic between microcontrollers, DSPs, and external peripherals. Its 128 macrocells are sufficient for chip-select decoding, wait-state generation, and interrupt steering, while the 10 ns propagation delay ensures setup/hold margins in high-speed DSP interfaces. JTAG-based in-system programmability enables late-stage board revisions without re-spinning the PCB, and the industrial -40C to +85C rating suits automotive under-hood and factory-floor controllers.
Recommended
Address Decoding & Memory Mapping
The EPM7128AETI144-10N is well-suited for address decoding in systems that map multiple memory banks, peripherals, or dual-port RAM. With 128 macrocells, the device can decode 24-bit or wider address buses and produce chip-select outputs in a single pass, while 5 V tolerant inputs on 3.3 V VCCIO allow interfacing to legacy 5 V memory buses. The 10 ns tPD fits comfortably inside typical memory access cycles of 30-50 ns, leaving timing margin for bus arbitration logic.
Recommended
Industrial Control State Machines
The EPM7128AETI144-10N delivers robust Moore/Mealy state machines for industrial control and instrumentation. Its EEPROM-based configuration means the device retains state at power-up without external boot memory - critical for deterministic startup sequences in process-control PLCs. The industrial -40C to +85C operating range covers factory-floor conditions, and 100 user I/O pins support multi-axis stepper/servo control with limit-switch monitoring and encoder feedback in a single chip.
Recommended
Communication Protocol Bridging
The EPM7128AETI144-10N bridges asynchronous and synchronous communication protocols such as UART, SPI, I2C, and parallel DSP HPI by implementing framing, CRC, and clock-domain crossing in programmable logic. The 10 ns tPD supports SPI clock rates above 30 MHz, and 100 user I/O pins allow multiple concurrent bridges to coexist. JTAG in-system programmability enables field firmware updates to support evolving protocol revisions.
Recommended
Legacy Peripheral Expansion Boards
The EPM7128AETI144-10N serves as a feature-rich I/O expander on legacy peripheral expansion boards where microcontrollers lack sufficient pins. With 100 user I/O pins and 128 macrocells, a single device can implement dozens of PWM channels, quadrature decoders, and GPIO extenders. Industrial temperature range and JTAG field programmability make it a long-life-cycle choice for industrial backplane and test-and-measurement expansion cards.

Key Differentiators
- Industrial temperature range with 10 ns speed grade (vs EPM7128AETC144-10N)

- Drop-in compatibility across the MAX 7000A TQFP-144 family (vs EPM570T144C5N)
Design Notes
Estimated: at VCCINT=3.3 V with 128 macrocells switching at 50 MHz, Icc is approximately 80-120 mA depending on output loading. Decouple VCCINT and VCCIO pins with one 0.1 uF X7R ceramic capacitor per supply pin plus a single 10 uF bulk capacitor near the device. Place the bulk capacitor within 5 mm of the closest VCC pin to suppress switching transients during ISP programming.
Route the four GCLK pins (GCLK1-GCLK3 and the dedicated clock/clear) on impedance-controlled traces with matched lengths (within 0.5 inches / 12 mm) to minimize clock skew. Keep JTAG signals (TCK, TMS, TDI, TDO) away from high-speed I/O switching lines to avoid coupling noise during in-system programming. Follow Altera's TQFP-144 land pattern with 0.5 mm pitch and 4 inner power/ground thermal vias under the exposed die attach pad.
The EPM7128AETI144-10N supports 5 V tolerant inputs on a 3.3 V VCCIO rail because the I/O cells use a dual-oxide process. When interfacing to 5 V logic, do not exceed the absolute maximum input voltage of 5.5 V and add 10 kohm series resistors on inputs that share a bus with hot-plug connectors. Outputs are 3.3 V CMOS; drive 5 V CMOS inputs through a 74HCT244 buffer if voltage translation is required.
Do not assume JTAG IDs are identical across speed grades - the BSDL file must be regenerated for each variant. Avoid using both OE1 and OE2 as global output enables if they have different timing - assign fast signals to OE1. When migrating from MAX 7000 to MAX II (EPM570), note that the JTAG instruction set and pinout differ; full PCB rework is required.
Compliance Information
