EPM240GT100C3 Tóm tắt

The Intel (formerly Altera) EPM240GT100C3 is a non-volatile 240-logic-element Complex Programmable Logic Device (CPLD) from the MAX II family, fabricated on a 0.18 µm 6-layer-metal flash process and housed in a 100-pin TQFP (16 × 16 mm, 0.5 mm pitch) package with 80 user I/Os. It delivers 192 macrocells, a 4.7 ns pin-to-pin propagation delay, an internal fMAX around 304 MHz, MultiVolt core I/O support from 1.5 V to 3.3 V, and an 8 Kbit User Flash Memory (UFM) block for non-volatile configuration storage.

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.

This page synthesizes distributor pricing, JTAG-programming guidance, drop-in same-brand and cross-brand alternatives, and PCB layout notes that go beyond what the manufacturer datasheet alone provides, helping engineers quickly validate a substitute or second source.

EPM240GT100C3 phù hợp cho 7 Áp dụngs: 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.

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.

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.

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.

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.

EPM240GT100C3 vs EPM240T100C5N - which is better for low-power designs?

The EPM240GT100C3 belongs to the lower-power MAX II G family, while the EPM240T100C5N is the standard MAX II variant. The G version typically draws less standby current due to internal architecture refinements, making it the better choice for battery-backed or always-on systems. Both share the 100-TQFP pinout and 240 LE / 192 macrocell resources, so PCB layouts are drop-in compatible.

EPM240GT100C3 vs EPM240T100C3N - what is the difference?

Both parts are 240-LE MAX II CPLDs in the 100-TQFP package, but the 'G' suffix on EPM240GT100C3 indicates the MAX II G (low-power) family, whereas the EPM240T100C3N is a standard MAX II device. The G variant offers reduced quiescent current at the cost of marginally different timing characteristics. Pin-outs and JTAG programming flow are identical, so existing 100-TQFP footprints are reusable.

When should I choose EPM240GT100C3 over EPM1270T144C5N?

Choose the EPM240GT100C3 (240 LE, 100-TQFP) when your design fits within ~192 macrocells and you prefer a smaller, lower-pin-count package with 80 user I/Os. Choose the EPM1270T144C5N (1270 LE, 144-TQFP) when your design requires substantially more logic, more I/O, or additional UFM storage. Both are MAX II family, share the Quartus II design flow, and JTAG-program the same way.

What is the best drop-in replacement for EPM240GT100C3?

The closest drop-in replacements for the EPM240GT100C3 (100-TQFP, 240 LE, MAX II G family) are EPM240GT100C5N (extended temperature, same footprint) and EPM240T100C5N (standard MAX II variant, same footprint). All three share the TQFP-100 pinout and 240-LE / 192-macrocell resources, so existing PCB land patterns do not require rework. A lower-cost alternative is EPM240F100C5N from the original MAX (not MAX II) family, which uses the same 100-pin TQFP pad pattern.

Is there a Xilinx equivalent for EPM240GT100C3?

Xilinx does not manufacture a direct functional equivalent to the MAX II CPLD family. The closest Xilinx alternatives are the CoolRunner-II family (e.g., XC2C64A in VQ44 or TQ144) or the smaller XO2-256 in TQ144, but none are pin-compatible drop-ins. Cross-brand migration to Xilinx typically requires PCB redesign because the package, pinout, and JTAG programming toolchain differ.

Where can I download the EPM240GT100C3 datasheet PDF?

The official EPM240GT100C3 datasheet is hosted in the MAX II Device Handbook on Altera.com (now archived at intel.com). The verified web data points to datasheet.iiic.cc which mirrors the original Altera PDF (file size 983 KB, published 2009-07-31). For the latest revision, always check the Intel FPGA documentation portal under MAX II CPLD legacy support. Third-party mirrors include digchip.info and FindIC.

Where can I find the EPM240GT100C3 pinout diagram?

The 100-TQFP pinout is documented in the MAX II Device Handbook, Chapter 1, Table 1-5 onward, which lists every pin and its dual-purpose function (user I/O vs JTAG vs power). A clean pinout diagram is also rendered on the EPM240GT100C3 product page on the XAIPART site, derived from the manufacturer PDF. JTAG pins are pins 1, 27, 73, and 99 on the 100-TQFP package per the verified web data.

What software is needed to program EPM240GT100C3?

EPM240GT100C3 is programmed using Altera Quartus II design software (versions 13.0sp1 and earlier support MAX II; the free Quartus II Web Edition is sufficient). The JTAG programmer can be the Altera USB-Blaster, ByteBlaster II, or any compatible IEEE 1149.1 SVF player. Programming files are generated in .pof or .jic format and loaded via the Quartus Programmer window.

Is EPM240GT100C3 still in production?

As of 2026-09-12, the EPM240GT100C3 remains active in Intel's legacy CPLD catalog with confirmed distributor stock of 7,328 pieces at Heisener. The MAX II family has been designated as a mature, long-term-supply product line rather than being actively recommended for new designs, but Intel continues to honor orders and provide datasheet support. Designers targeting new designs should evaluate MAX V as the recommended successor.

What are the key specifications of EPM240GT100C3 that engineers should know?

The EPM240GT100C3 combines 240 logic elements (192 macrocells), 80 user I/Os, 4.7 ns pin-to-pin delay, 304 MHz fMAX, MultiVolt I/O (1.5 V to 3.3 V banks), 8 Kbit on-chip User Flash Memory, and in-system JTAG programming in a 100-TQFP package. According to the MAX II device handbook, it operates across 0 °C to 85 °C with core voltage of 1.8 V and is built on a 0.18 µm flash process, providing instant-on non-volatile configuration suitable for deterministic, latency-critical glue logic.

Hướng dẫn chọn lựa

Choose EPM240GT100C3 when you need a non-volatile, instant-on CPLD with the lowest standby current in the MAX II family and the fastest speed grade (4.7 ns tPD, grade 3) for latency-critical glue logic in commercial-temperature (0 to 85 °C) products. The MAX II G 'G' suffix delivers reduced Icc versus the standard MAX II (EPM240T100C5N) while keeping the same 240 LE / 192 macrocell density and 100-TQFP footprint. For industrial temperature ranges (-40 to +100 °C), select EPM240GT100C5N instead - same footprint, slightly slower 5.0 ns timing, identical Quartus flow. For automotive or extended military temperature, pick EPM240T100A5NGA (AEC-Q100) or EPM240GM100C5N (-55 to +125 °C). Avoid the EPM240F100C5N unless you specifically need legacy MAX architecture and 5 V tolerance, since its macrocell architecture is older and consumes more quiescent current.

Ghi chú thiết kế

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.
