Typical Applications
EPM240GT100-5N is suitable for 6 applications: Bus Bridging and Protocol Conversion, Power Sequencing and Supervisory Logic, Industrial Control and Motor Drive Glue Logic, LED Display Driving and Multiplexing, JTAG Test Access and Board-Level Boundary Scan, Legacy TTL Glue Logic Replacement.
Bus Bridging and Protocol Conversion
The EPM240GT100-5N is widely used for bus bridging between mismatched interfaces such as SPI-to-I2C, UART-to-Parallel, or legacy 8-bit microprocessor buses to modern 16/32-bit processors. With 240 logic elements and 4.7 ns tPD, it can sustain byte-rate translation at speeds above 100 MHz, far exceeding most embedded peripheral clock rates. The on-chip 8 Kbits of user flash allows storage of configuration look-up tables and protocol IDs. Compared to an FPGA, the MAX II instant-on behavior means bus conversion is active within 0.5 ms of power-up - critical for systems where the host CPU expects peripherals present during boot. The TQFP-100 package provides 80 user I/Os, more than sufficient for parallel bus multiplexing. MultiVolt I/O banks let the device sit between 3.3V and 1.8V domains without external level translators. Typical reference designs include I2C-to-SPI bridges for sensor hubs and legacy peripheral emulators on modern SoCs.
Recommended
Power Sequencing and Supervisory Logic
The EPM240GT100-5N excels at power-sequencing applications in multi-rail systems where 3-8 supplies must come up in a specific order with controlled ramp rates. Its 4.7 ns propagation delay enables sub-microsecond response to voltage-fault conditions, faster than most microcontroller supervisory circuits. Non-volatile Flash configuration means the sequencing algorithm is active immediately at power-on, with no firmware boot wait. The 80 user I/Os accommodate up to 40 enable/disable control signals and 40 status feedback lines, sufficient for complex ATX, telecom, or server power architectures. According to typical Quartus reference designs, the EPM240GT100-5N is programmed as a state-machine-driven sequencer with adjustable delay counters. Compared to a discrete 74-series sequencer, the CPLD offers field-upgradeable timing parameters via JTAG without board rework. Industrial designs use the -I5N variant for -40C to +100C operation.
Recommended
Industrial Control and Motor Drive Glue Logic
In industrial control cabinets and motor drives, the EPM240GT100-5N provides deterministic glue logic between gate drivers, encoder feedback, fault monitoring circuits, and the main MCU or DSP. Its 4.7 ns tPD and 100 MHz performance easily handle PWM fault propagation within one switching cycle at 20 kHz, even with multiple simultaneous fault sources. The 8 Kbits of user flash can store factory calibration data, encoder index tables, or motor-specific parameters. Compared to an MCU implementing the same logic in firmware, the CPLD response is jitter-free and unaffected by software interrupts or RTOS scheduling latency. The TQFP-100 package supports up to 80 I/Os for interfacing to multiple encoder channels, Hall sensors, and isolated gate drivers. Typical applications include PLC digital I/O expansion, servo-drive signal conditioning, and industrial robot safety interlocks.
Recommended
LED Display Driving and Multiplexing
The EPM240GT100-5N drives multiplexed LED matrix displays, seven-segment clusters, and Charlieplexed LED arrays with deterministic timing. With 80 I/Os available, it can directly drive up to 10 common-anode 8-segment digits, or larger matrices using external drivers. The 4.7 ns propagation delay ensures no ghosting or cross-talk at refresh rates up to 1 kHz per row. On-chip flash storage holds font tables and animation patterns without external memory. Compared to discrete 74HC595 shift registers, the CPLD provides parallel random-access addressing and PWM dimming in a single chip, simplifying the BOM. Industrial signage, transportation departure boards, and instrument-panel displays commonly use MAX II CPLDs because of their long-term availability and instant-on behavior. The MultiVolt I/O supports direct interface to 5V LED driver ICs and 3.3V microcontrollers.
Recommended
JTAG Test Access and Board-Level Boundary Scan
The EPM240GT100-5N integrates naturally into JTAG-based board test architectures because it has a built-in IEEE 1149.1 boundary scan chain. Designers use it as a JTAG hub to bridge TAP signals between multiple inaccessible test points, or as a custom JTAG controller emulating proprietary test protocols. With 240 logic elements, the device can implement TAP state machines, instruction decoders, and IDCODE registers in addition to its primary logic function. The 80 user I/Os allow observation of up to 80 boundary nodes without adding dedicated test pins. Compared to dedicated JTAG controllers, the CPLD approach consolidates glue logic and test access in one package, reducing BOM count and improving test coverage. Programming via JTAG also enables in-field firmware updates without removing the board.
Recommended
Legacy TTL Glue Logic Replacement
Many legacy boards use 74LS, 74HC, and 74FTTL glue logic that is becoming hard to source. The EPM240GT100-5N consolidates 20-50 equivalent discrete gates into one package, reducing PCB area, power consumption, and part count. Each macrocell implements a sum-of-products or registered logic function that maps directly to standard TTL parts such as 74LS138 decoders, 74LS151 multiplexers, and 74LS161 counters. With 192 macrocells and 80 I/Os, the device replaces approximately 25-30 standard SSI/MSI TTL packages. Compared to discrete replacement, the CPLD approach is field-programmable via JTAG, so logic changes do not require respinning the PCB. Industrial users adopt MAX II for long-life-cycle products (15-20 years) where TTL obsolescence is a major risk. The instant-on Flash configuration eliminates the boot delay of SRAM-based FPGAs.

Key Differentiators
- Instant-on non-volatile Flash configuration (vs EPM570GT100-5N)
- TQFP-100 footprint shared across MAX II density points (vs EPM570GT100-5N)
- LUT-based architecture unusual for CPLDs (vs EPM240T100C5N)
- Commercial temperature optimized for cost (vs EPM240GT100I5N)
Design Notes
Estimated: At typical operation with 240 LE active at 50 MHz toggle rate and 80 I/Os at 25 MHz, the EPM240GT100-5N consumes approximately 50 mA from VCCINT (3.3V) and 20-30 mA total from VCCIO banks (per bank depends on I/O utilization and toggle rate). Place one 0.1 uF X7R ceramic decoupling capacitor adjacent to each VCCINT pin (typically 4 pins distributed around the package) and one 10 uF bulk tantalum or ceramic capacitor near the VCCINT cluster. Each VCCIO bank requires its own 0.1 uF decoupling capacitor. Estimated: total quiescent current is approximately 30 mA at room temperature, well within the 500 mA PCB thermal budget.
The TQFP-100 package has a 14x14 mm body with 0.5 mm pitch leads and a 1.0 mm total lead span. Follow standard TQFP PCB design rules: 0.2 mm trace width with 0.2 mm spacing to escape the leads, and a via-in-pad or micro-via fan-out for inner pads. Use a 4-layer or higher stackup with continuous ground plane directly under the device for thermal dissipation and signal return paths. Estimated: ground plane continuity below the device improves IO bank signal integrity at 100 MHz operation. For high-speed JTAG chains keep the TMS/TCK traces under 100 mm length to avoid signal integrity issues.
Three common pitfalls when designing with the EPM240GT100-5N: (1) do not leave JTAG pins floating - TMS, TCK, and TDI require pull-ups to VCCIO4 because the JTAG TAP controller is always active; (2) do not assume VCCIO banks can be powered independently - all four VCCIO banks must be powered for the device to function, even if unused; (3) ensure nCONFIG is tied high through a 10 kohm pull-up to VCCIO - leaving it floating causes unpredictable configuration behavior at power-up. According to the MAX II Device Handbook, nSTATUS requires a 10 kohm pull-up to VCCIO because it is open-drain.
For I/O signals above 50 MHz, use 50 ohm characteristic impedance traces and series-terminate at the driver when the trace length exceeds approximately one-quarter of the signal rise time. The MultiVolt I/O supports 1.5/1.8/2.5/3.3V outputs but slew rate control is fixed by the device - external damping resistors (22-33 ohm) may be required on long traces to adjacent high-speed memories. LVDS and HSTL I/O standards are not supported on MAX II - use external translators for these interfaces. Estimated: typical output rise/fall time is 2-4 ns at 50 pF load.
