Typical Applications
EPM240GT100C4 is suitable for 6 applications: FPGA / SoC Power-Up Sequencing Controller, Multi-Voltage I/O Expansion and Level Translation, JTAG Bus Controller and Test Access Multiplexer, Glue Logic Consolidation (74-series Replacement), User Flash Memory (UFM) for Board Parameter Storage, LED Display and Indicator Multiplexing Controller.
FPGA / SoC Power-Up Sequencing Controller
The EPM240GT100C4 is purpose-built for power-up sequencing controllers in multi-rail systems where FPGA, SoC, DDR, and peripheral rails must come up in a deterministic order. The device's instant-on non-volatile flash architecture powers up in microseconds with all logic active, eliminating the millisecond boot delay of SRAM FPGAs and ensuring the first rail is gated correctly before subsequent rails enable. Its 240 logic elements easily encode 4-8 rail sequencer state machines with PG-good and EN daisy chains, while the 4.7 ns tPD keeps rail-to-rail delay under 50 ns. The 80 user I/O pins accommodate per-rail enable, power-good, and fault inputs.
Recommended
Multi-Voltage I/O Expansion and Level Translation
The EPM240GT100C4's MultiVolt I/O architecture makes it a natural bridge between 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains in mixed-voltage boards. Designers route 5 V-tolerant tolerant-tolerant tolerant signals from a legacy peripheral through the CPLD's I/O banks, each powered by its own VCCIO rail matched to the connected device, achieving bidirectional level translation without dedicated translator ICs. The 240 LE capacity handles 16-32 channel translation arrays plus control logic, and the 4.7 ns tPD adds negligible latency. This eliminates the BOM cost and board area of TXS/TXB translator chips in cost-sensitive consumer designs.
Recommended
JTAG Bus Controller and Test Access Multiplexer
The EPM240GT100C4 serves as a JTAG test-access multiplexer in production-test architectures that need to share a single JTAG header across multiple boundary-scan devices. Its 240 LEs easily encode a 4-to-1 or 8-to-1 TAP multiplexer state machine with TMS/TCK/TDI/TDO steering, while the 80 user I/O pins carry dedicated scan paths to each downstream device. The MAX II device's JTAG ISP compliance (IEEE 1149.1) lets the CPLD itself be reconfigured in-system alongside the devices under test, enabling board-level TAP cascade management in telecom and industrial backplanes where ATE access is required.
Recommended
Glue Logic Consolidation (74-series Replacement)
The EPM240GT100C4 excels at replacing multiple 74HC/74AHC/74LVT discrete logic packages on legacy boards with a single programmable device. Typical consolidation examples include replacing 3-5 packages of address latches, bus transceivers, AND/OR gate arrays, and parity generators with one MAX II CPLD, reducing PCB area by 60-80% and improving noise margins through controlled output slew rates. The 240 LE capacity covers 5-10 medium-complexity glue functions, and the deterministic 4.7 ns tPD preserves the timing margins that discrete logic provided. Designers maintain a single sourceable BOM line instead of multiple 74-series parts.
Recommended
User Flash Memory (UFM) for Board Parameter Storage
The EPM240GT100C4 integrates an 8 Kbit User Flash Memory block alongside the logic array, enabling non-volatile storage of board revision codes, MAC addresses, calibration constants, and serial numbers without a separate EEPROM. At power-up the UFM contents are instantly readable by internal logic and can be exposed to an external microcontroller via a SPI/I2C-style soft-interface implemented in the 240 LEs. This eliminates the cost of a 24Cxx EEPROM and the I2C bus lines, reducing BOM count in compact industrial sensor and IoT designs. The flash cell is rated for typical 100K program/erase cycles per MAX II handbook.
Recommended
LED Display and Indicator Multiplexing Controller
The EPM240GT100C4 drives multiplexed 7-segment or dot-matrix LED displays in industrial HMIs and consumer appliances, where its instant-on flash architecture eliminates the visible boot flicker that microcontroller-based drivers exhibit. Its 80 I/O pins drive row/column drivers directly, while the 4.7 ns tPD enables >1 kHz refresh rates with zero visible flicker. The 240 LEs encode character ROMs, brightness-control PWM, and chip-select decoders for up to 16-digit displays, all non-volatile and instant-on. Designers benefit from reduced microcontroller firmware burden and deterministic display refresh timing.

Key Differentiators
- Lowest-density MAX II with full TQFP-100 I/O count (vs EPM1270T144C5N)
- -7 speed grade timing advantage (vs EPM240T100C5N)
- N-suffix lead-free variant vs base part availability (vs EPM240GT100C4N)
Design Notes
The EPM240GT100C4 requires two distinct supply rails: VCCINT (3.3 V core) and one or more VCCIO bank supplies (1.5/1.8/2.5/3.3 V). Each VCCIO bank can be driven independently to support mixed-voltage I/O; tie all VCCIO pins of an unused bank to VCCINT (3.3 V) to keep them in a defined state. Decoupling: place one 0.1 µF X7R ceramic capacitor within 5 mm of each VCCINT pin and one per VCCIO bank, plus a bulk 10 µF tantalum or ceramic capacitor adjacent to the CPLD. Power sequencing: VCCINT must rise before or simultaneously with VCCIO to avoid latch-up; the device tolerates either order per MAX II handbook.
The TQFP-100 package has 0.5 mm lead pitch and gull-wing leads; route signals on inner layers only when escape routing is feasible, and use via-in-pad or micro-via technology for BGA variants (M100). Place the JTAG header (TMS/TCK/TDO/TDI/VCC/GND) within 50 mm trace length of the CPLD to ensure signal integrity at 10 MHz TCK rates; if longer, add a 4.7 kΩ pull-up on TMS and TDI. Exposed pad (TQFP-100 has no EP; only BGA/M100 variants do): confirm PCB thermal relief vias under any exposed pad on related packages to meet θJA. Keep high-speed switching traces (≥50 MHz) at least 3w away from analog signals on the same MultiVolt bank.
When using the EPM240GT100C4 as a level translator between 5 V TTL and 3.3 V LVCMOS, ensure that the 3.3 V VCCIO bank does not receive 5 V inputs without external clamping; the MAX II I/O is NOT 5 V tolerant. For true 5 V tolerance, use an external resistor divider (2:1) or a dedicated TXB/TXS translator IC. Drive strength: configure I/O pins as 8 mA or 16 mA current strength in the Quartus assignment editor for high-fanout nets; default 4 mA may not meet timing on heavily-loaded address/data buses.
Common pitfalls when designing with the EPM240GT100C4: (1) Forget to assign JTAGEN or JTAG pins in the Quartus pin planner — leaving them as 'unused' will float the JTAG TAP and lock the device from re-programming. (2) Use the wrong MSEL/auto-config mode — EPM240GT does not require MSEL configuration pins like Cyclone FPGAs; this is a non-volatile flash device with implicit ISP. (3) Confuse speed-grade suffix: -7 = 4.7 ns tPD (fastest), -8 = slower, -10 = slowest commercial grade. (4) Exceed UFM endurance — the 8 Kbit User Flash Memory has 100K program/erase cycles limit, unsuitable for high-write-rate parameter logging.
Compliance Information
RoHS and REACH compliance status not explicitly confirmed in verified web data; the FindIC listing notes 'LEAD FREE' for EPM240GT100C4 but full RoHS declaration should be requested from Intel FPGA. The EPM240GT100C4N is the explicitly lead-free N-suffix variant per MAX II ordering guide.
