EPM240GT100C3 Übersicht
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses a small number of macrocells based on sum-of-products logic to implement glue logic, bus bridges, and high-speed control functions. It sits in the digital logic hierarchy between discrete 74-series logic gates and FPGAs, providing deterministic timing, instant-on operation from internal flash, and pin-to-pin delays measured in single-digit nanoseconds. CPLDs are preferred over FPGAs when design size is modest, latency must be guaranteed, and the device must boot without external configuration memory.
Key features include in-system programmability via IEEE 1149.1 JTAG, support for 1.8 V, 2.5 V, and 3.3 V I/O banks (MultiVolt core), built-in boundary-scan (BST) circuitry, and an on-chip User Flash Memory that can hold user data such as serial numbers or boot parameters. The MAX II architecture replaces conventional EEPROM-based CPLDs with a flash-based lookup table approach, lowering power consumption and supporting higher I/O density per macrocell.
Typical applications include bus-interface bridging (e.g., 8/16/32-bit asynchronous glue logic), LED display control, address decoding for microprocessors, state-machine implementation, power-supply sequencing, and I/O expansion for microcontrollers. The instant-on, non-volatile nature of the device makes it well suited to systems that must operate immediately at power-up without waiting for an FPGA bitstream to load.
A primary design trade-off is fixed pin assignment: the JTAG pins (TDI, TDO, TMS, TCK) are dedicated and cannot be used as user I/O when JTAG is enabled. Designs should reserve these pins or disable JTAG in the Quartus configuration if general-purpose I/O is required on those pads. Operating junction temperature spans 0 °C to 85 °C for the commercial grade C3 suffix.

Typische Anwendungen
EPM240GT100C3 ist geeignet für 7 Anwendungs: Microprocessor Bus Interface Bridging, I/O Expansion for Microcontrollers, LED Display and Signage Control, Power Supply Sequencing and Supervisor Logic, Industrial Control and Factory Automation, Legacy System Modernization and 5 V-to-3.3 V Bridge, Consumer Electronics and Display Adapters.
Microprocessor Bus Interface Bridging
The EPM240GT100C3 is well suited as a bus-interface bridge between microprocessors, microcontrollers, and peripherals that operate at different voltage levels or widths. Its 80 user I/Os and MultiVolt support (1.5 V, 1.8 V, 2.5 V, 3.3 V) allow direct connection to legacy 5 V-tolerant buses and modern 1.8 V cores without external level shifters. The 4.7 ns pin-to-pin delay ensures deterministic address-latch and chip-select timing critical for asynchronous SRAM/Flash/PCMCIA glue logic. Instant-on non-volatile configuration means the bridge is operational within microseconds of power-up, eliminating FPGA bitstream load delays in boot-critical systems.
Empfohlen
I/O Expansion for Microcontrollers
Adding digital I/O to a microcontroller with limited pin count is a classic MAX II use case. The EPM240GT100C3 provides 80 general-purpose I/O lines that can be addressed via SPI, I2C, or parallel interfaces using a small footprint of macrocells for the state machine. The instant-on flash-based configuration means expansion logic is ready before the MCU finishes its bootloader. Designers typically implement keypad scanning, LED matrix driving, or relay multiplexing in this role, taking advantage of the device's deterministic 4.7 ns propagation delay.
Empfohlen
LED Display and Signage Control
Large LED matrices and scrolling-sign displays require deterministic row/column scanning and pulse-width modulation that benefit from a CPLD's single-digit-nanosecond predictability. The EPM240GT100C3's 80 user I/Os can drive multiplexed 7-segment or RGB LED arrays up to about 8 × 10 channels per device. Its on-chip 8 Kbit User Flash Memory can store lookup tables, gamma curves, or animation frame descriptors, reducing external ROM requirements. Multiple EPM240GT100C3 devices can be cascaded for higher-resolution displays while maintaining synchronized timing thanks to the global clock network.
Empfohlen
Power Supply Sequencing and Supervisor Logic
Multi-rail systems (CPU core, DDR memory, I/O, analog) require precise power-up and power-down sequencing to prevent latch-up and in-rush damage. The EPM240GT100C3 implements supervisor state machines with programmable delays and voltage-detect inputs, replacing discrete RC timer networks and complex PLD logic. Its instant-on, non-volatile configuration ensures the sequencer is active before the rails begin ramping, while the 4.7 ns propagation delay enables fast fault response. The MAX II G family's low quiescent current makes it suitable for always-on sequencing in energy-conscious designs.
Empfohlen
Industrial Control and Factory Automation
Programmable logic controllers (PLCs), motor-control boards, and factory-automation gateways use the EPM240GT100C3 for encoder decoding, quadrature counting, and high-speed digital filter preprocessing. The 100-TQFP package and 0 °C to 85 °C commercial temperature range are adequate for enclosed control cabinets; industrial temperature variants (EPM240GT100C5N or EPM240GM100C5N) extend coverage to -40 °C to 100 °C. Deterministic timing is essential for safe industrial-control loops where FPGA bitstream variability cannot be tolerated.
Empfohlen
Legacy System Modernization and 5 V-to-3.3 V Bridge
The EPM240GT100C3 is widely deployed as a glue-logic translator between legacy 5 V peripherals and modern 3.3 V processors. With MultiVolt I/O, each bank can be independently powered at 1.5 V, 1.8 V, 2.5 V, or 3.3 V, enabling direct voltage translation without external buffers. This is especially valuable in defense, aerospace, and medical equipment that must interface with legacy buses (VME, ISA, PCI). Drop-in replacement of legacy 5 V GAL/PAL devices with this CPLD consolidates multiple functions into a single instant-on package.
Empfohlen
Consumer Electronics and Display Adapters
The EPM240GT100C3 is used in consumer products such as digital cameras, set-top boxes, and home routers to perform protocol conversion (LVDS-to-CMOS, parallel-to-SPI), timing generation, and HDMI/DVI auxiliary-channel handling. Its small 16 × 16 mm TQFP footprint and modest power consumption suit compact PCBs. The on-chip 8 Kbit UFM stores device-specific serial numbers, EDID tables, or HDMI key data, reducing external EEPROM count and BOM cost.

Designhinweise
Estimated: The EPM240GT100C3 has separate VCCINT (1.8 V core) and VCCIO1..4 (1.5/1.8/2.5/3.3 V I/O banks). Decouple each VCCINT pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the pad, and each VCCIO bank with its own 0.1 µF plus a bulk 10 µF tantalum or ceramic. Power sequencing is not strictly required per the MAX II handbook, but a simultaneous or core-first ramp prevents I/O driving into unpowered input structures. A ferrite bead on each VCCIO rail can reduce switch-injected noise from digital glue logic back into sensitive analog rails.
The 100-TQFP uses 0.5 mm pitch leads on a 16 × 16 mm body. Recommended land pattern is IPC-7351 nominal with 0.30 mm pad width and 0.20 mm lead-to-pad overlap. Route JTAG signals (TDI/TDO/TMS/TCK) away from high-current switching traces; keep total JTAG stub length below 25 mm and place a 10 kΩ pull-up on TCK and TMS, plus a 10 kΩ pull-up on TDI for board-level reliability. Expose JTAG header on prototype boards so the Quartus Programmer can attach via USB-Blaster. A solid 4-layer stackup with continuous ground plane beneath the device is recommended for signal integrity on the high-speed user I/Os.
Three recurring design pitfalls: (1) Treating JTAG pins as general-purpose I/O - they are dedicated when JTAG is enabled; either disable JTAG in the Quartus device options to reclaim them as GPIO, or document that pins 1, 27, 73, 99 are JTAG-only. (2) Mixing VCCIO voltages across banks - each bank (1-4) has its own VCCIO pin; tying 3.3 V and 1.8 V peripherals to the same bank will damage the lower-voltage device. (3) Forgetting the UFM lock bit - if your design stores proprietary data in the 8 Kbit UFM, set the lock bit via Quartus to prevent readback during JTAG programming, otherwise factory test fixtures can read customer data.
