EPM570GT100C3N Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the hierarchy between simple SPLDs/PLDs and FPGAs. It uses a small AND/OR fabric (here, 440 macrocells arranged in Logic Array Blocks) to implement combinational and registered logic. Compared with FPGAs, CPLDs offer lower power, deterministic timing, and instant-on behavior. Within Intel's portfolio, the MAX II family occupies the glue-logic and control-plane role, sitting between the MAX 10 and the Cyclone series. The 'G' suffix indicates a 'Green' power variant of the original MAX II family.
Key features of the EPM570GT100C3N include 8 Kbits of user Flash memory, MultiVolt I/O supporting 1.5/1.8/2.5/3.3 V interfaces, bus-hold circuitry on user I/O, JTAG-based in-system programmability, and support for the Quartus II design software. The 100-pin TQFP package supports commercial operating junction temperature (0C to 85C). The 76 available user I/O pins (after subtracting JTAG, power, and dedicated configuration pins from the 100-pin count) are sufficient to interface multiple microcontrollers, bus bridges, and glue-logic functions in a single device.
The internal architecture combines a flash-based configuration store with a multi-level interconnect, four LABs feeding into macrocells with configurable flip-flops, and a JTAG-compliant boundary scan chain. This architecture yields deterministic 5.4 ns tPD regardless of logic utilization, a hallmark of CPLDs versus SRAM-based FPGAs. The MultiVolt core and I/O rails allow direct interfacing with 3.3 V MCUs and 1.8 V ASICs from a single chip.
Typical applications include bus-interface bridging (PCI to local bus, I2C/SPI multiplexing), I/O expansion for microcontrollers, power-sequencer and reset-controller logic, motor-control state machines, LED-display drivers, and industrial control glue logic. The instant-on behavior is favored in industrial automation where the controller must be ready within milliseconds of power-up.
A key design consideration is that 100-pin TQFP packages are hand-solderable and rework-friendly, unlike BGA variants in the same family. Designers migrating from the older MAX II to MAX II G should verify the VCCINT supply ramp and JTAG chain because, although pin-compatible, internal supply tolerances differ between the two revisions.

Typical Applications
EPM570GT100C3N is suitable for 6 applications: Bus-Interface Bridging, I/O Expansion for Microcontrollers, Power-Sequencer / Reset Controller, Motor-Control State Machine, LED Display Driver / Multiplexer, Industrial Glue Logic.
Bus-Interface Bridging
The EPM570GT100C3N is well-suited for bus-interface bridging tasks such as PCI-to-local-bus, I2C-to-SPI muxing, and UART-to-parallel conversion. With 570 logic elements, 440 macrocells, and 5.4 ns pin-to-pin delay, the device can implement wide multiplexers and address/data demuxers in a single chip while maintaining deterministic timing across all 76 user I/O. Its MultiVolt I/O (1.5/1.8/2.5/3.3 V) lets it bridge a 3.3 V MCU to a 1.8 V ASIC directly. The instant-on Flash configuration eliminates the boot PROM typical of SRAM FPGAs, reducing BOM cost in bridges between legacy microcontrollers and modern SoCs in industrial control boards.
Recommended
I/O Expansion for Microcontrollers
When an MCU runs out of GPIO or peripheral channels, the EPM570GT100C3N provides 76 user I/O plus 8 Kbits of user Flash as a low-latency expansion port. The 5.4 ns tPD allows the CPLD to act as a high-speed coprocessor implementing PWM generators, quadrature decoders, or custom serial protocols without burdening the MCU. MultiVolt I/O means it can be wired directly to 1.8 V, 2.5 V, or 3.3 V MCUs without level shifters. Quartus II supports graphical state-machine entry, making it easy to add deterministic logic blocks alongside Cortex-M or PIC microcontrollers in motor-control and sensor-interface designs.
Recommended
Power-Sequencer / Reset Controller
The EPM570GT100C3N is widely used as a multi-rail power-sequencer and reset-distribution controller in ATCA, telecom, and server boards. With 5.4 ns deterministic delay, the device can implement programmable power-up/power-down sequencing across 6-12 voltage rails using its 440 macrocells, with feedback via GPIO and timers. The 1.8 V core draws minimal quiescent current and the flash-based configuration is instant-on, ensuring sequencing starts within microseconds of supply ramp. MultiVolt I/O can monitor 3.3 V enable signals and drive 1.8 V reset lines to ASICs from a single chip, replacing discrete supervisor ICs in cost-sensitive designs.
Recommended
Motor-Control State Machine
Industrial motor drives benefit from the EPM570GT100C3N's deterministic 5.4 ns timing and 76 I/O when implementing BLDC/PMSM commutation tables, Hall-sensor decoding, and PWM dead-time generation. The 440 macrocells are sufficient to hold a 6-step or FOC commutation lookup alongside multiple PWM channels, while MultiVolt I/O interfaces with 3.3 V MCUs and 1.8 V gate drivers. The 0C-85C commercial temperature range suits most industrial enclosures, and the MAX II G ('Green') variant offers low quiescent current important for battery-backed drives. Designers can simulate state machines in Quartus II and verify timing closure before silicon.
Recommended
LED Display Driver / Multiplexer
Large LED walls, scoreboards, and signage controllers leverage the EPM570GT100C3N's 76 user I/O to drive high-current row/column drivers and minimize MCU interrupt load. The 5.4 ns tPD supports scanning rates beyond 1 MHz, enabling 16+ row multiplex without flicker, while 440 macrocells handle gamma-correction lookup tables and refresh counters. MultiVolt I/O ties directly to 3.3 V shift registers or 5 V TTL buffers via external FETs. Flash-based instant-on eliminates the boot delay seen with FPGA-based LED controllers, allowing displays to be ready within 100 ms of power-up in retail and stadium installations.
Recommended
Industrial Glue Logic
Factory-automation backplanes and PLC I/O modules use the EPM570GT100C3N as classic glue logic: address decoding, chip-select generation, watchdog reset, and protocol translation between Modbus, CAN, and proprietary fieldbuses. The 100-pin TQFP is hand-solderable and rework-friendly, important for industrial customers with long lifecycles (10+ years). 8 Kbits of user Flash stores node IDs, calibration constants, and serial numbers, while MultiVolt I/O talks to legacy 5 V TTL peripherals via 3.3 V bank + 5 V tolerant input. Quartus II compatibility with VHDL/Verilog makes migration to MAX 10 trivial when a refresh is needed.

Design Notes
The EPM570GT100C3N requires two distinct supplies: VCCINT (1.71-1.89 V, 1.8 V typical) for the core logic and VCCIOx (one per I/O bank, 1.5/1.8/2.5/3.3 V) for the I/O drivers. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 100 mils of the pin, and add one bulk 10 uF tantalum or ceramic per supply rail. Power-on ramp must be monotonic; if the VCCINT rail glitches during programming the JTAG chain may corrupt the configuration Flash. Tie CONF_DONE and nSTATUS high via 10 kohm pull-ups because they are open-drain.
The 100-pin TQFP package has 0.5 mm lead pitch, which requires careful PCB layout: use 0.15 mm-wide solder paste apertures (5-mil stencil), guard traces between pads to prevent solder bridging, and provide a continuous ground plane beneath the device for thermal spreading and return-path integrity. Keep JTAG signals (TDI/TDO/TMS/TCK) short and isolated from switching I/O; add 10 kohm pull-ups on TMS and TCK as recommended by the MAX II handbook. Total package thermal resistance (theta_JA) for TQFP-100 is approximately 35 C/W on a 4-layer JEDEC test board - acceptable for the <300 mW typical dissipation of this part.
Do not confuse the EPM570GT100C3N (MAX II G, 1.8 V core) with the original EPM570T100C5N (MAX II, 3.3 V core) - they are pin-compatible but NOT drop-in substitutes because the VCCINT supply differs. Always check the second letter: 'G' = MAX II G (1.8 V core), 'F' or 'T' = original MAX II (3.3 V core). When migrating from MAX II to MAX II G, also verify the Quartus II device selection matches the silicon revision; an older bitstream will not load on the newer 'G' silicon. Estimated: typical IccINT at 50 MHz is approximately 30 mA for utilization below 50%.
Although CPLDs have slower edge rates than FPGAs, the EPM570GT100C3N can still drive 50 ohm controlled-impedance traces at 100 MHz if outputs are configured as 3-state with slew-rate limiting. For signals above 50 MHz, series-terminate the output with 33-ohm resistors placed within 200 mils of the CPLD pin to dampen reflections on the TQFP-100 lead frame. MultiVolt I/O banks allow mixing 3.3 V and 1.8 V buses on the same device, but unused I/O pins must be configured as outputs driving ground (not floating) to avoid supply-current transients during configuration.
Compliance Information
RoHS compliant and lead-free per Altera/Intel product declaration. Not AEC-Q100 qualified - automotive customers should use the industrial-temperature I5N variant after their own qualification. Halogen-free status not explicitly confirmed in the available data.
