EPM240T1OOC5N Обзор

The Intel (Altera) EPM240T1OOC5N is a MAX II instant-on, non-volatile CPLD from the MAX II Device Family featuring 192 macro cells (240 logic elements) at up to 201.1 MHz internal performance, fabricated on a 0.18 µm, six-layer-metal flash process in a 100-pin TQFP package with 2.5 V/3.3 V operation.

A CPLD (Complex Programmable Logic Device) is a non-volatile, instant-on programmable logic IC that combines multiple PAL-like logic blocks with a programmable interconnect matrix. CPLDs sit below FPGAs in density and sit above discrete 74-series glue logic in flexibility; they are used for I/O expansion, bus bridging, power-up sequencing, and state-machine replacement where deterministic, low-latency, non-volatile behavior is required. The MAX II family adds 8 Kbits of user flash memory and removes the legacy EEPROM/CMOS-cell architecture of MAX 7000, lowering power and cost.

Key features include 192 macro cells, 80 I/O pins, 8 Kbits of internal user flash memory, JTAG-based in-system programmability (IEEE 1149.1), 4-input look-up tables, and zero-power versus commercial junction temperature grades. The 100-pin TQFP package supports vertical migration to higher-density MAX II devices (EPM570, EPM1270, EPM2210) in the same footprint, preserving PCB design across multiple logic-density points.

Architecturally, the EPM240T100C5N uses a non-volatile flash-based configuration cell so it powers up in a defined state within microseconds - a major advantage over SRAM FPGAs that require an external boot PROM and configuration time. MultiVolt I/O supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces from a single 3.3 V core supply, simplifying mixed-voltage board designs.

Typical applications include I/O expansion and voltage translation in industrial control boards, glue logic replacement in telecom/networking line cards, bus-interface bridging (PCI to local bus, address decoding), power-up/power-down sequencing in ATCA/ATX platforms, and LED-control or motor-control state machines in consumer and industrial equipment.

When designing with this device, use the Intel Quartus Prime design suite (free Web Edition supports MAX II) for synthesis, place-and-route, programming-file generation, and JTAG programming via the Altera USB-Blaster or compatible cable. Decouple all VCCINT/VCCIO pins with 0.1 µF capacitors placed within 100 mils of the package pins.

EPM240T1OOC5N подходит для 6 применениеs: I/O Expansion & Voltage Translation, Industrial Control & Glue Logic, Telecom & Networking Line Cards, Power Sequencing & Housekeeping, LED Control & Display Driving, Bus Interface Bridging.

🔧

I/O Expansion & Voltage Translation

The EPM240T100C5N's 80 user I/Os and MultiVolt I/O bank support (1.5 V / 1.8 V / 2.5 V / 3.3 V) make it ideal for I/O expansion and voltage translation between mixed-voltage peripherals and processors. Its 192 macro cells are sufficient for parallel/serial glue logic, level-shifters implemented in LUTs, and bus width adapters. Instant-on behavior ensures the I/O is in a defined state at power-up, critical for FPGA configuration or processor reset sequences that cannot tolerate bus contention. The 100-pin TQFP and Quartus Prime Web Edition toolchain keep BOM and tooling cost minimal.

This single-rail core + multi-rail I/O design eliminates the need for separate 2.5 V and 3.3 V regulators in mixed-voltage designs, simplifying board power architecture.

How many logic elements and macro cells does EPM240T100C5N have?

The EPM240T100C5N contains 240 logic elements organized into 192 macro cells. Each macro cell combines a 4-input look-up table (LUT), a programmable register, and dedicated carry/control logic, giving the device roughly 192 flip-flops plus combinational capacity - sufficient for typical glue-logic, address-decoding, and state-machine workloads but well below mid-range FPGA density.

What package does EPM240T100C5N use?

The EPM240T100C5N ships in a 100-pin TQFP (Thin Quad Flat Pack) package, with 80 user I/O pins available for application use. The 100-pin TQFP is a low-cost, hand-solderable, and socket-compatible footprint shared across multiple MAX II densities (EPM240, EPM570, EPM1270, EPM2210), enabling PCB reuse when logic requirements grow.

Where to buy EPM240T100C5N at the best price?

As of 2026-09-12, the EPM240T100C5N is in stock at DigiKey (part 544-1964-ND) at approximately $6.85 in single-piece quantity with volume breaks to roughly $4.20 at 1,000 pieces. Mouser and major authorized distributors also stock the part; lead time is typically 6-12 weeks for factory-direct orders. Independent distributors may quote lower but carry authenticity risk - always verify lot traceability.

What is the lead time for EPM240T100C5N?

As of 2026-09-12, factory-direct lead time for the EPM240T100C5N is approximately 8-12 weeks per Altera/Intel distributor listings, with distributor shelf stock available immediately in single-piece to a few-hundred-piece quantities. For high-volume orders (greater than 5,000 units), the orderable lead time typically extends to 14-16 weeks due to MAX II being on a mature, long-lifecycle process node.

What is the difference between EPM240T100C5N and EPM240T100I5N?

The EPM240T100C5N is the commercial temperature-grade variant (0 °C to +85 °C) while the EPM240T100I5N is the industrial temperature-grade variant (-40 °C to +100 °C). Both share the identical 100-pin TQFP package, 192 macro cells, and 201.1 MHz fMAX, making the EPM240T100I5N a drop-in thermal upgrade when applications require extended cold-temperature operation.

EPM240T100C5N vs EPM240GT100C5N - which is better for low-power designs?

The EPM240GT100C5N is the MAX II G variant featuring zero-power technology with lower static current (typically 2 mA vs. higher in standard MAX II) and additional power-saving features, per Intel/Altera datasheets. For battery-backed or always-on applications, the G variant is preferred; for standard industrial glue logic where power is not critical, the standard EPM240T100C5N is the more cost-effective choice with identical logic density.

When should I choose EPM240T100C5N over EPM1270T144C5N?

Choose the EPM240T100C5N when your design fits within 192 macro cells / 240 logic elements and you want the lowest per-unit cost in the 100-pin TQFP footprint. Choose the EPM1270T144C5N when you need 980 logic elements, 116 user I/Os, or 144-pin TQFP headroom for future expansion - but note the 144-pin TQFP is a different footprint requiring PCB layout changes.

What is the best drop-in replacement for EPM240T100C5N?

The best drop-in replacement is the EPM240T100I5N, which shares the identical 100-pin TQFP footprint, 192 macro cells, and 201.1 MHz fMAX but extends the operating temperature range to -40 °C to +100 °C industrial grade. The EPM240GT100C5N is also pin-compatible with lower static power consumption. Both are listed in XAIPART's Site MPN database for direct cross-reference.

Is there an equivalent alternative to EPM240T100C5N from another brand?

Direct cross-brand pin-compatible equivalents for the EPM240T100C5N (100-pin TQFP, MAX II architecture, 192 macro cells) are limited because MAX II's instant-on non-volatile architecture is proprietary to Intel/Altera. Xilinx CoolRunner-II family parts (XC2C64A, XC2C128, XC2C256) target similar density ranges and I/O counts in 100-pin TQFP packages, but require complete design re-synthesis due to differing architectures and toolchains.

Where can I download the EPM240T100C5N datasheet PDF?

The EPM240T100C5N datasheet PDF can be downloaded from the Altera Semiconductor archive (alterasemi.com) at the URL https://www.alterasemi.com/datasheet/alterasemi/EPM240T100C5N.pdf, or from the original Alldatasheet mirror. Intel's official MAX II Device Handbook (Section I) is the authoritative reference for DC/AC electrical characteristics, timing, and pinout.

Where is the EPM240T100C5N pinout defined?

The EPM240T100C5N pinout is defined in the Altera MAX II Device Handbook Section I, available as a multi-section PDF. Pin 1 is located at the top-left of the 100-pin TQFP package when the orientation marker is in the upper-left; standard pin assignments are documented in the device datasheet's 'Pin Information' table, with VCCINT/VCCIO and GND pins on multiple sides for robust power delivery.

Does EPM240T100C5N require an external configuration memory?

No, the EPM240T100C5N does not require an external configuration memory. As a MAX II non-volatile flash-based CPLD, configuration is stored on-chip and the device powers up in a defined functional state within microseconds, eliminating the boot PROM required by SRAM FPGAs. Programming is performed via the JTAG interface (IEEE 1149.1) using Quartus Prime and the Altera USB-Blaster cable.

What software is required to program the EPM240T100C5N?

The EPM240T100C5N is programmed using Intel Quartus Prime design software (Web Edition is free and supports MAX II), combined with the Altera USB-Blaster or compatible JTAG download cable. The toolchain handles Verilog/VHDL synthesis, place-and-route, timing analysis, and JTAG programming; older Quartus II versions (13.0 and earlier) also support MAX II but may lack newer device support.

What are the key specifications of EPM240T100C5N that engineers should know?

The EPM240T100C5N is a MAX II instant-on non-volatile CPLD with 192 macro cells, 240 logic elements, 80 user I/Os, 8 Kbits of user flash, and fMAX of 201.1 MHz, fabricated on 0.18 µm flash process in a 100-pin TQFP. It supports MultiVolt I/O (1.5 V / 1.8 V / 2.5 V / 3.3 V) from a 3.3 V core supply, JTAG ISP per IEEE 1149.1, and zero standby power in commercial grade - the lowest-cost entry point into the MAX II family.

Руководство по выбору

Choose the EPM240T100C5N when you need the lowest-cost MAX II CPLD with 192 macro cells, 80 user I/Os, and 100-pin TQFP footprint for commercial-temperature (0-85 °C) glue-logic, I/O expansion, and bus-bridging applications. Choose the EPM240T100I5N if your design must operate from -40 °C to +100 °C industrial temperature range - same pinout, same die. Choose the EPM240GT100C5N if you need the zero-power G variant for always-on battery-backed designs (lower static IQ). Choose the EPM570T100C5N when logic exceeds 192 macro cells but you want to retain the same 100-pin TQFP PCB layout (vertical migration per MAX II datasheet). Choose Xilinx XC2C64A or XC2C128 for cross-brand sourcing flexibility, but only if you can absorb the toolchain switch to Xilinx ISE/Vivado and design re-synthesis. All five parts share the 100-pin TQFP footprint, enabling PCB reuse across commercial/industrial/zero-power/vertical-migration variants.

Заметки по проектированию

Estimated: The EPM240T100C5N's 3.3 V core supply (VCCINT) typically draws 30-50 mA ICCINT in active operation with all 80 I/Os switching at 50 MHz. Decouple VCCINT with at least one 0.1 µF ceramic capacitor placed within 100 mils of pin 79 (VCCINT) and pin 80 (GND), plus a 10 µF bulk capacitor on the supply rail. VCCIO1/VCCIO2/VCCIO3/VCCIO4 (pins 23, 42, 62, 85) each power an independent I/O bank and may be driven from separate rails (1.5 V / 1.8 V / 2.5 V / 3.3 V) - each requires its own 0.1 µF decoupling cap to its bank GND.

Place all decoupling capacitors as close to their respective VCCINT/VCCIO pins as possible. Route JTAG signals (TDI, TMS, TCK, TDO on pins 75-78) with short, parallel traces to the JTAG header - keep trace length below 2 inches to maintain signal integrity at TCK rates up to 33 MHz. Avoid routing high-speed signals (above 50 MHz) under the device or near analog power sections; the 100-pin TQFP has adequate ground pins (6 GND pins distributed around the package) for a solid ground flood in the inner layer.

Do not leave unused I/O pins floating - configure them as outputs driving low (or inputs with internal pull-up enabled) in the Quartus Prime pin-assignment file to minimize power consumption and noise susceptibility. Avoid exceeding 3.6 V on any VCCIO pin; the absolute-maximum VCCIO is 3.6 V even though recommended operation is 3.3 V. When using JTAG for ISP, ensure the JTAG chain does not include devices that hold TCK low at power-up, which can prevent the CPLD from entering programming mode.

Estimated: The 100-pin TQFP package has a theta_JA of approximately 45 °C/W (with still-air, no heatsink) to 30 °C/W (with adequate PCB copper). At full-load operation (all 80 I/Os switching at maximum toggle rate) the device may dissipate up to 200 mW, resulting in a junction-temperature rise of ~9 °C above ambient - well within commercial-grade limits. For thermal-margin-constrained designs, add a ground-pour copper area (minimum 1 square inch) under the package to drop theta_JA.
