EPM240T100C5N Overview
What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic IC that sits between simple glue-logic gates and higher-density FPGAs. CPLDs typically combine a small AND/OR PLA-style fabric with a programmable interconnect matrix and a non-volatile configuration memory, providing instant-on behavior (no boot PROM required), deterministic timing, and excellent pin-to-pin delay predictability. Within the programmable logic taxonomy, the MAX II family occupies the low-density, low-power, instant-on tier — useful for I/O expansion, bus bridging, power-sequencing logic, and configuration control where FPGAs would be overkill.
The EPM240T100C5N delivers 80 user I/O pins with MultiVolt I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V) on the same bank, enabling direct interfacing with mixed-voltage rails without level shifters. The device supports in-system programmability through IEEE 1149.1 (JTAG) and operates from a 2.5 V / 3.3 V core supply. Internal 8 Kbits of user flash allow storing non-volatile configuration data, custom IDs, or boot records without an external PROM.
Architecturally, the MAX II CPLD uses a Logic Array Block (LAB) based fabric interconnected through a MultiTrack interconnect, with each LAB containing 10 Logic Elements. The device provides four I/O banks, JTAG boundary-scan, and a built-in oscillator. With a propagation delay around 4.7 ns and a maximum internal frequency near 201.1 MHz, the EPM240T100C5N comfortably addresses glue-logic, address decoding, LED/H-bridge control, and high-speed bus-interface applications.
Typical applications include industrial control boards, telecom base-station glue logic, motor control pre-drivers, I/O expansion for microcontrollers, address decoding for memory subsystems, and portable / handheld consumer devices. Its instant-on behavior is especially valuable in power-sequencing and boot-loader roles.
A key design consideration: the 100-TQFP package requires careful PCB layout because it lacks an exposed thermal pad, so all dissipation must flow through the peripheral leads — provide at least 4-layer stack-up with continuous ground plane. Programming is performed via the Quartus II / Quartus Prime design suite and a JTAG download cable (USB-Blaster or compatible).

Typical Applications
EPM240T100C5N is suitable for 6 applications: Industrial Control & PLC Glue Logic, I/O Expansion & Bus Bridging for Microcontrollers, Telecom Base Station Glue Logic, Motor Control Pre-Driver Logic, Memory Address Decoding & Chip-Select Generation, Portable & Handheld Consumer Devices.
Industrial Control & PLC Glue Logic
The EPM240T100C5N's 240 Logic Elements, 4.7 ns pin-to-pin delay, and instant-on non-volatile configuration make it an ideal glue-logic device for industrial PLC and controller boards. It handles address decoding, interrupt steering, watchdog supervision, and bus multiplexing between microcontrollers, FPGAs, and peripheral ICs. The MultiVolt I/O banks (1.5/1.8/2.5/3.3 V) directly interface with mixed-voltage rails without external level shifters, reducing BOM count. Quartus Prime support with JTAG in-system programming allows fast board-bring-up and field firmware updates. Industrial designers pair the CPLD with a host MCU for deterministic I/O timing that no software loop can match.
Recommended
I/O Expansion & Bus Bridging for Microcontrollers
When a microcontroller lacks sufficient GPIO, UART, SPI, or I2C ports, the EPM240T100C5N adds programmable I/O expansion and protocol bridging. Its 80 user I/O pins far exceed typical MCU GPIO counts, and the 4 MultiVolt banks let it sit between a 1.8 V MCU and 3.3 V peripherals with no level shifting. Engineers implement custom serial protocols, PWM generators, and quadrature decoders in VHDL/Verilog, achieving nanosecond-level deterministic latency impossible in software. The instant-on behavior means expansion logic is available before the MCU boots — critical for power-sequencing roles.
Recommended
Telecom Base Station Glue Logic
In telecom base-station line cards, the EPM240T100C5N performs board-level glue logic: clock distribution, reset sequencing, status-LED driving, and backplane bus arbitration. Its 4.7 ns tPD and 201.1 MHz internal frequency comfortably handle 100 MHz+ backplane signals, while the 8 Kbits of user flash store board ID, revision codes, and boot logs that survive power cycles. The 100-TQFP footprint integrates easily onto high-density line-card PCBs. The commercial 0–85 °C operating range suits environmentally controlled base-station shelves.
Recommended
Motor Control Pre-Driver Logic
Motor-control boards use the EPM240T100C5N as a pre-driver controller: it generates PWM timing, Hall-sensor decoding, fault-interrupt aggregation, and brake-control sequencing before the MCU samples the rotor position. With 4.7 ns propagation, the CPLD responds to overcurrent and desaturation faults within nanoseconds — much faster than any MCU ISR. The instant-on behavior guarantees safe motor-braking on power-up, and the MultiVolt I/O banks accept 3.3 V logic from MCU plus 5 V signals from gate drivers directly. Quartus state machines implement field-oriented-control commutation tables in hardware.
Recommended
Memory Address Decoding & Chip-Select Generation
The EPM240T100C5N excels at memory-subsystem address decoding and chip-select generation for multi-bank SRAM, NOR flash, and DDR interfaces. Its 240 LEs hold dozens of independent address comparators, while the 4.7 ns propagation delay aligns CS timing tightly with MCU read/write strobes. The non-volatile flash stores boot configuration that survives power cycles, eliminating external jumper resistors for chip-select mapping. The 4 MultiVolt I/O banks let the CPLD bridge 1.8 V DDR and 3.3 V flash without level shifters, simplifying PCB layout and reducing BOM.
Recommended
Portable & Handheld Consumer Devices
Battery-powered handheld devices benefit from the EPM240T100C5N's instant-on non-volatile configuration and low standby current. The CPLD replaces discrete glue-logic gates (74HC series), saving PCB area, reducing quiescent draw, and consolidating functions like key-scan matrix decoding, LCD segment driving, and power-rail sequencing into a single IC. The 100-TQFP package, though larger than QFN options, is well-suited to hand-solderable prototypes and small-volume production. Quartus IP libraries provide ready-made key-scanner, PWM, and I2C-bus-controller cores that engineers instantiate in minutes.

Key Differentiators
- True drop-in upgrade path to EPM570T100C5N with same 100-TQFP footprint (vs EPM240T100C5 (same brand, same package, same speed grade))
- Internal non-volatile flash enables instant-on with zero boot delay (vs Small FPGA (e.g., Cyclone IV equivalent))
- 4 independent MultiVolt I/O banks eliminate external level shifters (vs Discrete 74-series glue logic (74HC/74AHC))
Design Notes
The 100-TQFP package (14 × 14 × 1.0 mm) has no exposed thermal pad, so all heat dissipation flows through the 100 peripheral leads. Use a 4-layer PCB with continuous inner ground plane directly beneath the device; flood the top and bottom layers with copper pours stitched to GND with vias on a 1 mm grid. Keep all high-speed traces on inner layers to maintain signal integrity on the 80 user I/O signals. Decoupling: place one 0.1 µF X7R ceramic per VCCIO bank and one 10 µF tantalum or polymer bulk cap adjacent to VCCINT, all within 5 mm of the package.
Each of the 4 I/O banks operates at an independent VCCIO (1.5/1.8/2.5/3.3 V), so group I/O by destination voltage to avoid level-shifter circuitry. Drive JTAG signals TCK, TMS, TDI, TDO with short traces (≤ 50 mm) and a 10 kΩ pull-up on TCK and TMS per IEEE 1149.1 recommendations. For high-speed outputs (> 50 MHz), enable Quartus slew-rate and current-strength settings and verify with IBIS simulation; unmatched impedance causes reflections on the 100-TQFP lead-frame traces.
Common design pitfalls: (1) Mixing 5 V signals into VCCIO banks — MultiVolt I/O supports up to 3.3 V on user I/O; 5 V tolerance is NOT guaranteed and will damage the device. (2) Forgetting to strap MSEL/DEV_OE pins correctly in Quartus pin assignments, leading to unconfigured outputs after programming. (3) Exceeding 80 user I/O assignments — the 100-TQFP exposes 80 user I/O and the rest are JTAG/VCC/GND; over-assignment causes Quartus fitter errors. (4) Using the wrong speed grade when migrating to EPM240T100C5 vs C4 vs C3 — propagation delay differs (~33% slower at C3).
Compliance Information
RoHS compliance confirmed by distributor listings (DigiKey, Mouser). 'N' suffix indicates Pb-free finish per Altera ordering information. AEC-Q100 not applicable — automotive applications require AEC-Q100-qualified parts; MAX II CPLDs are commercial/industrial grade. REACH compliance assumed per Altera product-level statements but not directly verified in the provided web data.
