Typical Applications
EPM3128ATI100-10 is suitable for 6 applications: Address Decoding and Glue Logic, Power-Up and Power-Down Sequencing Controllers, PCI Bus Interface and Target Bridge Logic, Industrial Control and Factory Automation, LED Display and Signage Driving, Legacy Bus Bridging and Interface Conversion.
Address Decoding and Glue Logic
The EPM3128ATI100-10 is well suited for address decoding and board-level glue logic in microprocessor and microcontroller systems where deterministic timing and instant-on behavior matter. Its 10 ns pin-to-pin delay handles 50 MHz address buses with margin, and 80 user I/Os accommodate multi-bank memory decoding across 16 to 24 address lines plus control signals (RD, WR, CS). Unlike SRAM-based FPGAs that need a boot PROM, the EEPROM-based MAX 3000A enters its programmed state within microseconds of VCC ramp, eliminating PROM cost and start-up latency. The 3.3 V core with MultiVolt I/O interfaces directly with 5.0 V, 3.3 V, and 2.5 V logic without level shifters, simplifying mixed-voltage PCB designs. Industrial temperature rating (-40 to +85 °C) supports factory-floor and outdoor enclosures.
Recommended
Power-Up and Power-Down Sequencing Controllers
The EPM3128ATI100-10 functions as a deterministic power-sequencing controller in multi-rail systems where ASICs, FPGAs, and DSPs require specific rail-on order during start-up and reverse order during shutdown. The 128 macro cells implement cascaded delay timers, watchdog state machines, and PG (power-good) feedback combiners in a single chip. EEPROM-based configuration guarantees the programmed sequence is active immediately on VCC ramp, eliminating the mis-ordering risk of SRAM-based logic. With 80 I/Os, the device can directly drive 30+ enable pins and monitor PG feedback signals. The 3.3 V core with 5 V-tolerant I/O interfaces directly with most regulator enable inputs without level translation. Industrial temperature rating fits telecom and industrial chassis operating from -40 to +85 °C ambient.
Recommended
PCI Bus Interface and Target Bridge Logic
The EPM3128ATI100-10 serves as a PCI target interface bridge in industrial cards, imaging boards, and embedded PCs where PCI bus cycle decoding, parity generation, and target-assertion logic are needed. The MAX 3000A family supports 5.0 V PCI signaling levels directly through MultiVolt I/O, and the 128-macro-cell capacity handles address decoding, command validation, and interrupt steering in a single device. 80 user I/Os accommodate the 32-bit multiplexed AD bus plus C/BE#, FRAME#, IRDY#, TRDY#, DEVSEL#, and PAR signals. With 10 ns tPD, the device meets 33 MHz PCI timing with comfortable margin. Non-volatile EEPROM configuration means the PCI target logic is active at POR before BIOS enumeration, enabling legacy boot scenarios. Industrial temperature supports chassis-mounted cards in factory environments.
Recommended
Industrial Control and Factory Automation
In industrial control systems, the EPM3128ATI100-10 implements deterministic glue logic, encoder decoding, PWM generation, and interlock safety logic on PLC backplanes and motor-control boards. Its industrial temperature rating (-40 to +85 °C) is essential for factory-floor enclosures, while EEPROM-based instant-on ensures deterministic logic state at every cold-start without depending on configuration loading. 80 user I/Os drive opto-isolated outputs, accept 24 V industrial sensor inputs via MultiVolt tolerant pins, and handle encoder quadrature decoding at up to 227.3 MHz. The 10 ns tPD suits 50 MHz encoder inputs and sub-microsecond response to safety interlock chains. JTAG boundary-scan enables in-system test coverage for board-level manufacturing diagnostics on assembled PLC boards.
Recommended
LED Display and Signage Driving
The EPM3128ATI100-10 drives multiplexed LED matrices, scrolling signs, and large 7-segment displays where many high-current sink lines must be scanned in a deterministic sequence. The 80 user I/Os handle row/column multiplexing for 8x8 to 16x16 RGB LED matrices with row-refresh rates exceeding 1 kHz, eliminating visible flicker. The 227.3 MHz counter frequency supports high-bit-depth PWM dimming (10+ bits) at refresh rates above 200 Hz. MultiVolt I/O drives 5 V logic-level LED driver chips and 3.3 V shift registers without translation. Industrial temperature rating suits outdoor signage in cold-climate and high-ambient deployments. EEPROM-based configuration retains custom animations and brightness schedules through power cycles without external storage.
Recommended
Legacy Bus Bridging and Interface Conversion
The EPM3128ATI100-10 bridges between legacy parallel buses (ISA, PC/104, VME) and modern peripherals, or converts between 8/16/32-bit bus widths with custom byte-swapping and protocol translation. With 128 macro cells, designers can implement full state machines for bus handshaking, wait-state insertion, and protocol adapters in a single chip. The 10 ns tPD handles 25 MHz ISA bus timing with substantial margin, and the 80 user I/Os accommodate 32-bit data plus 24-bit address plus control signal multiplexing. EEPROM-based instant-on is critical for legacy systems that expect I/O devices to be ready before BIOS completes enumeration. Industrial temperature and long-life-cycle support suit military, aerospace, and industrial retrofit programs that must maintain legacy interfaces for decades.

Key Differentiators
- Industrial temperature range with same speed grade (vs EPM3128ATC100-10)
- Standard (non-N) speed/density in industrial temperature (vs EPM3128ATC100-10N)
- Slower speed grade allows lower dynamic current (vs EPM3128ATC100-7)
- EEPROM instant-on versus SRAM-based FPGA boot time (vs Cyclone IV EP4CE6 in EQFP-144)
Design Notes
The TQFP-100 package has 0.5 mm lead pitch (or 1.0 mm body pitch) requiring 4-mil traces and 8-mil spaces between adjacent leads for fanout. Per Altera MAX 3000A layout guidelines, place at least 4 GND and 2 VCC pins distributed around the package - these are NOT all bonded to the same internal plane, so each must be individually decoupled with 0.1 µF X7R ceramic placed within 3 mm of the pin. Use a continuous ground plane on layer 2 beneath the device to provide low-impedance return for the high-frequency I/O switching currents.
The MAX 3000A core draws ICCINT of approximately 100 to 200 mA static plus dynamic current proportional to switching frequency. Estimate: at 50 MHz toggle rate across 40 I/Os, ICCINT rises by another 50 to 80 mA. Total worst-case ICCINT is around 300 mA; choose a regulator rated for at least 500 mA to maintain headroom. Add a 10 µF tantalum or ceramic bulk capacitor near VCCINT pins in addition to per-pin 0.1 µF decoupling. Power-up ramp should be monotonic and faster than 1 ms to ensure clean JTAG ISP - use a regulator with soft-start or supervise VCC with a reset IC if the bulk capacitance is large.
Do not connect any user I/O pin to a voltage above 5.5 V - even though MultiVolt tolerates 5.0 V logic, the absolute maximum VCCIO is 4.6 V and exceeding this during hot-plug events will permanently damage the input ESD structure. Avoid leaving unused I/O pins floating: configure them as outputs driving low in the Quartus II device settings, or as inputs with the internal pull-up enabled. Floating inputs can oscillate and draw excess ICC. The JTAG TDI/TMS pins must be pulled up to VCCIO through 10 kΩ resistors if the JTAG header is not populated, to prevent spurious JTAG state transitions during board reset.
When using the EPM3128ATI100-10 to generate clocks, place the clock-output pin adjacent to a GND pin for reduced return-path inductance. Programmable slew-rate control (slow/fast) in the Quartus II device options can trade off edge rate against EMI - select 'slow slew rate' on outputs driving cables or backplanes to reduce radiated emissions by 6 to 10 dB. For outputs above 20 MHz, the 3.3 V LVTTL drive strength (default 4 mA) may be insufficient; increase to 8 or 12 mA in the pin-assignment editor if the receiver is far from the CPLD or heavily loaded.
Compliance Information
RoHS/lead-free status not explicitly confirmed in the Verified Web Data for the -10 (non-N) suffix. The -10N suffix variants in the same family are explicitly lead-free/RoHS. Industrial temperature does not imply AEC-Q100 qualification - this CPLD is not automotive-grade. Compliance values are conservatively marked 'unknown' where the verified data did not explicitly state them.
