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 combine a small AND/OR PLA-style fabric with a programmable interconnect matrix and non-volatile configuration memory, providing instant-on behavior (no boot PROM required), deterministic timing, and predictable pin-to-pin delays. Within the programmable-logic taxonomy (CPLD -> programmable logic -> logic IC), 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.
Key features include 80 user I/O pins with MultiVolt I/O (1.5 V, 1.8 V, 2.5 V, 3.3 V on the same bank) enabling direct mixed-voltage interfacing without level shifters, an internal user flash of 8 Kbits, IEEE 1149.1 JTAG boundary-scan with in-system programmability, a built-in internal oscillator, and four I/O banks. The 2.5 V / 3.3 V core supply plus bank-isolated VCCIO rails allow the same device to drive 1.5 V CMOS, 1.8 V LVCMOS, 2.5 V, and 3.3 V logic on the same PCB.
Architecturally, the MAX II CPLD uses a Logic Array Block (LAB) fabric interconnected through a MultiTrack interconnect; each LAB contains 10 Logic Elements. The device delivers a maximum internal frequency near 201.1 MHz with a 4.7 ns pin-to-pin delay, deterministic routing, and zero boot latency because the configuration is stored in on-chip flash. Compared with SRAM-based FPGAs, this removes the external configuration PROM and the boot-time wait, while consuming less active and standby power.
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 where the rest of the system must see valid control signals at power-up.
A key design consideration: the 100-pin TQFP lacks an exposed thermal pad, so all dissipation flows through the peripheral leads - use a 4-layer stack-up with a continuous ground plane and stitch the lead-pour copper to maximize heat removal. Programming is performed with the Quartus II / Quartus Prime design suite and a JTAG download cable such as USB-Blaster. RoHS-compliant and lead-free per the Intel product page.

Ứng dụng tiêu biểu
EPM240T100C5N phù hợp cho 7 Áp dụngs: Industrial Control Glue Logic, Telecom Base-Station Bus Bridging, Motor-Control Pre-Driver Logic, I/O Expansion for Microcontrollers, Memory Address Decoding & Chip-Select Generation, Portable / Handheld Consumer Devices, Power-Sequencing and Boot-Loader Logic.
Industrial Control Glue Logic
The EPM240T100C5N's 240 logic elements, 4.7 ns pin-to-pin delay, and 80 MultiVolt I/Os make it ideal for industrial glue logic on PLC backplanes, sensor hubs, and motor-control interface boards. With 1.5 V-3.3 V VCCIO on four banks, the device can simultaneously interface 1.8 V MCUs, 2.5 V ADCs, and 3.3 V communication transceivers on the same board. Its instant-on behavior is critical in safety circuits that must assert control signals at power-up before any MCU boots. Use it to debounce encoders, decode address lines for parallel SRAM/Flash, generate timing waveforms, and arbitrate bus contention. The 100-pin TQFP footprint accommodates roughly 80 GPIOs after JTAG and supply pins, leaving headroom for status LEDs, fault outputs, and SPI/I2C bridges without external logic ICs.

Telecom Base-Station Bus Bridging
In telecom line cards and base-station backhaul boards, the EPM240T100C5N bridges between legacy parallel buses (PCI, local bus, EBI) and modern serial links (SPI, I2C, UART) that the host ASIC/FPGA does not handle natively. The 201.1 MHz fMAX and 4.7 ns tPD comfortably convert 66 MHz-133 MHz local bus signals, while MultiVolt I/O means the same CPLD can sit between 1.5 V LVCMOS ASIC pins and 3.3 V transceiver pins without level shifters. The 8 Kbits of on-chip flash can store vendor IDs, hardware revision codes, or strap settings read at boot, eliminating an external EEPROM. JTAG ISP enables board-level in-system programming during manufacturing and field upgrades.
Được đề xuất
Motor-Control Pre-Driver Logic
The EPM240T100C5N is widely used as the pre-driver sequencer in BLDC and stepper-motor controller boards, where it generates PWM dead-time, fault-mux logic, and Hall-sensor decoding before passing clean control signals to gate drivers. Its 4.7 ns propagation delay delivers deterministic dead-time insertion that protects the half-bridge from shoot-through, and the 80 GPIOs comfortably drive 6-step or FOC commutation tables for 3-phase systems. The instant-on flash-based configuration is critical at startup: motor controllers must assert safe states (all gates low) the moment power is applied, with no boot-PROM latency. MultiVolt I/O supports direct connection to 3.3 V MCU timers and 1.8 V encoder ICs.

I/O Expansion for Microcontrollers
When a small MCU lacks enough GPIOs for keypad scanning, LCD multiplexing, or LED matrix driving, the EPM240T100C5N adds up to 80 additional pins through a simple SPI or I2C expansion interface. The CPLD's deterministic 4.7 ns timing eliminates the software jitter typical of bit-banged MCU expansion, enabling clean keypad debouncing and glitch-free PWM generation for LED dimming. Because the configuration lives in on-chip flash, the expansion ports are available at the moment of power-up - useful for booting displays that require a fixed initialization waveform before the MCU finishes its own boot sequence. MultiVolt I/O allows the same CPLD to drive 1.8 V, 2.5 V, and 3.3 V peripherals on a mixed-rail board.

Memory Address Decoding & Chip-Select Generation
Classic CPLD use case: the EPM240T100C5N generates glitch-free chip-select signals for parallel SRAM, NOR flash, and peripheral memory maps from a single high-order address bus. With 4.7 ns tPD and 201.1 MHz fMAX, it comfortably decodes address spaces up to 133 MHz without inserting wait states, and its zero-boot-time flash configuration means CS lines are valid the instant the system powers up. The 4-bank MultiVolt I/O lets the same decoder drive 1.8 V mobile DDR and 3.3 V legacy flash without external transceivers. 8 Kbits of user flash stores the memory-map revision, jumper settings, or boot-time configuration words, eliminating an external EEPROM.

Portable / Handheld Consumer Devices
Battery-powered handheld devices benefit from the EPM240T100C5N's low standby current and instant-on flash-based configuration. Designers use it as a power-Management companion that asserts rail-enable signals in the correct sequence before the main SoC boots, then handles button-matrix scanning, RGB-LED driving, and haptic-actuator PWM after boot. The 100-pin TQFP at 14x14 mm fits compact motherboards, while the 8 Kbits of user flash can store device-unique calibration data that would otherwise require an external EEPROM. MultiVolt I/O supports both 1.8 V sensors and 3.3 V display drivers from the same chip, saving board area and BOM cost.
Được đề xuất
Power-Sequencing and Boot-Loader Logic
The EPM240T100C5N is a classic power-sequencer for multi-rail systems: with non-volatile on-chip flash and zero boot time, it can assert enable signals for DC-DC converters, hold the system in reset, and release the CPU only after all rails are stable. Its 4.7 ns propagation delay lets the sequencer react to PG (power-good) faults in microseconds, and 80 GPIOs handle sequenced enables for up to 20 rails with redundancy. The 8 Kbit flash can store the golden boot image, watchdog timeout, and fault-recovery FSM. MultiVolt I/O means the sequencer itself can be powered from 3.3 V while monitoring 1.0 V-5.0 V rails through resistive dividers.

Ghi chú thiết kế
Estimated: the 100-pin TQFP package has no exposed thermal pad, so all heat from the MAX II core must dissipate through the 100 peripheral leads. For typical CPLD designs running below 50 MHz, dissipation stays under 100 mW and a 4-layer FR-4 stack-up with a continuous ground plane is adequate. If the design approaches the 201.1 MHz fMAX limit and toggles many GPIOs simultaneously, increase the lead-pour copper area under the TQFP and stitch thermal vias near the GND pins to keep junction rise below 20 °C.
Decouple every VCCINT pin with a 0.1 µF X7R ceramic placed within 50 mils of the pad, and pair each VCCIO bank supply pin with its own 0.1 µF + 10 µF bulk. Because the MAX II has four independent VCCIO banks, a noisy 3.3 V bank can be isolated from a quiet 1.8 V bank with separate ferrite beads. Route the JTAG chain (TCK/TMS/TDO/TDI) as a 4-wire daisy chain with 4.7 kΩ pull-ups on TCK/TMS/TDI and place the JTAG header within 6 inches of the device to keep signal integrity within the IEEE 1149.1 spec.
Common pitfalls: (1) do not confuse the standard MAX II (2.5 V / 3.3 V VCCINT) with the MAX II G (1.8 V VCCINT) - the EPM240GT100C5N is a different core rail and is NOT a drop-in VCCINT-compatible swap. (2) Quartus II legacy projects must be re-targeted to Quartus Prime for the latest device support; older SOF/POF files may need regeneration. (3) The commercial C-suffix part is rated 0 °C to +85 °C only - substitute the I-suffix (industrial) variant for outdoor or extended-temperature designs. (4) On power-up, hold nCONFIG low for at least 100 µs after VCCINT reaches 90 % of nominal to ensure clean configuration from on-chip flash.
Route all four JTAG signals together with matched lengths (within 500 mils) and keep them away from high-edge-rate clocks. Place the JTAG header on the same board edge as the device when possible, and add a 4.7 kΩ pull-up on nSTATUS to VCCIO since it is open-drain. For multi-drop JTAG chains (MAX II + FPGA + CPLD on the same TCK), insert a series 33 Ω resistor near each TDI pin to dampen reflections. The MultiTrack interconnect inside the MAX II is deterministic, so once Quartus TimeQuest reports timing closure, board-level routing changes do not affect internal timing margins.
