Typical Applications
EPM240GT100C4N is suitable for 6 applications: Bus Bridging and Protocol Conversion, Industrial Control and Glue Logic Replacement, I/O Expansion for Microcontrollers, Address Decoding and Chip Select Generation, LED Display and Signage Control, Test and Measurement Front-End Logic.
Bus Bridging and Protocol Conversion
The EPM240GT100C4N excels at bus-bridging between mismatched voltage domains and protocols in industrial and embedded systems. Its MultiVolt I/O support (1.5/1.8/2.5/3.3 V) allows direct interfacing between legacy 5 V-tolerant busses via external resistors and modern 1.8 V processors without external level shifters. With 80 user I/Os in the TQFP-100 package and a 6.1 ns tPD, the device can implement address-latch, chip-select decode, and width-conversion logic between 8/16/32-bit busses running at 50-80 MHz. The instant-on flash-based architecture means bus bridges come up active in microseconds, which is critical when a host CPU needs immediate access to peripheral memory at reset.
Recommended
Industrial Control and Glue Logic Replacement
In factory-automation and motor-control boards, the EPM240GT100C4N replaces dozens of discrete 74-series glue-logic ICs with a single programmable device, reducing board area and BOM cost. With 192 macro cells and 240 logic elements, it can implement complete state machines, PWM interfaces, and encoder-decoders for servo drives. The 100-pin TQFP package's 80 user I/Os comfortably handle 4-6 incremental encoder channels plus parallel I/O expansion. The non-volatile flash configuration eliminates external boot PROMs and provides field-upgradeability via JTAG without removing the device from the board.
Recommended
I/O Expansion for Microcontrollers
When a microcontroller's GPIO count is insufficient, the EPM240GT100C4N serves as a programmable I/O expander connected via SPI or parallel bus. Each of the 80 user I/Os can be configured as input, output, or bidirectional with custom interrupt-on-change logic. The 247.5 MHz maximum internal frequency allows the CPLD to handle high-speed pulse trains and quadrature decoding that would otherwise burden the MCU's CPU. With a 6.1 ns propagation delay, interrupt-to-output response stays below 20 ns total including bus access, making it suitable for real-time industrial protocols.
Recommended
Address Decoding and Chip Select Generation
The EPM240GT100C4N is widely deployed for address decoding and chip-select generation in 16/32-bit embedded systems, where it replaces discrete PAL/GAL devices and 74HC138/139 decoders. With 192 macro cells and a 6.1 ns tPD, the device can decode up to 8-12 chip-select outputs from a 24-bit address bus with less than 15 ns of added access time. The flash-based configuration allows late-stage board redefinition - designers can change memory maps on the production line via JTAG without respinning the PCB, a major advantage over hard-wired decoders.
Recommended
LED Display and Signage Control
Lighting and signage controllers use the EPM240GT100C4N to multiplex rows and columns of LED matrices, generate PWM dimming waveforms, and scan push-button/keypad inputs simultaneously. With 80 user I/Os, a single device can drive a 16-row by 16-column LED matrix with 256 pixels while still leaving pins for status LEDs and serial interfaces. The instant-on capability ensures that LED patterns appear within milliseconds of power-up, eliminating the visible flicker that SRAM-based FPGAs exhibit during their configuration phase.
Recommended
Test and Measurement Front-End Logic
Test-and-measurement instruments deploy the EPM240GT100C4N as a flexible front-end for signal routing, range switching, and trigger conditioning. Its 6.1 ns tPD allows the device to participate in sub-100 MHz trigger logic without degrading measurement bandwidth, while 80 user I/Os accommodate multi-channel multiplexer control. The JTAG ISP capability lets manufacturers reuse the same hardware across multiple product variants by simply reprogramming the CPLD, compressing inventory SKUs and shortening time-to-market.

Key Differentiators
- Instant-on non-volatile flash configuration (vs Small SRAM-based FPGAs (e.g., Cyclone series))
- Multi-voltage I/O without external level shifters (vs Discrete 74-series glue logic)
- Higher user I/O count at same density (vs EPM1270T144C5N (144-pin TQFP, 980 LEs))
Design Notes
The TQFP-100 package uses 0.5 mm pitch leads, which requires careful PCB design: use 0.2-0.25 mm trace-and-space with solder mask defined (SMD) pads for reliable assembly. Place all four board layers with a continuous ground plane directly under the device to provide thermal dissipation and controlled impedance for high-speed I/O. Keep JTAG traces (TCK, TMS, TDI, TDO) short and isolated from switching signals to avoid programming failures.
Do not exceed the 4.6 V absolute maximum I/O voltage, even on unused pins - configure unused I/Os as inputs with internal weak pull-ups in the Quartus pin-assignment file to prevent floating-pin oscillation that can raise ICC. When mixing 3.3 V and 1.8 V I/O banks, ensure each VCCIO bank has its own decoupling capacitor pair (0.1 µF plus 10 µF) placed within 5 mm of the corresponding supply pin.
The 247.5 MHz internal frequency can drive I/O transitions in the 80-150 MHz range, so treat all output signals as transmission lines for traces longer than 25 mm. Use 33 Ω series-termination resistors at the CPLD output for traces exceeding one-quarter of the signal rise time in electrical length. For clock outputs, route on an inner layer stripline with reference ground plane on both sides to minimize radiated EMI.
Compliance Information
The 'N' suffix confirms lead-free / RoHS-compliant terminal finish per EU Directive 2002/95/EC. REACH, halogen-free, and conflict-mineral statements are not present in the verified web data and should be requested from Intel directly for compliance audits.
