EPM240T100C3 개요

The Intel (formerly Altera) EPM240T100C3 is a MAX II family Complex Programmable Logic Device (CPLD) delivering 192 macrocells, 240 logic elements, and up to 80 user I/Os in a 100-pin TQFP (14x14 mm) package with a commercial 0C to 85C operating temperature grade. It operates from an internal core supply of 2.5 V or 3.3 V, supports in-system programmability through JTAG, and consumes a typical standby current of roughly 2 mA for low-power glue-logic applications.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile, flash- or EEPROM-backed programmable logic device that sits between simple PAL/GAL SPLDs and FPGAs in the programmable logic hierarchy. Compared to FPGAs, CPLDs offer instant-on configuration (no external boot PROM), deterministic timing with predictable pin-to-pin propagation delays, and excellent general-purpose I/O density at lower cost. They are widely used for I/O expansion, bus bridging, power-up sequencing, address decoding, and logic integration on cost-sensitive boards where FPGAs would be overkill.

The EPM240T100C3 specifically belongs to the MAX II G (Green) family and features Instant-On capability, MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and a built-in User Flash Memory (UFM) block. Designers can also benefit from Altera/Intel Quartus II design software support, a generous JTAG-based ISP interface, and pin-compatible migration to higher-density MAX II devices like the EPM570 and EPM1270.

Typical applications include I/O voltage translation and level shifting in mixed-voltage designs, bus multiplexing and address decoding for microprocessors and DSPs, configuration and control logic for FPGAs and SoCs, board-level glue logic replacing discrete 74-series gates, and digital signal conditioning or interface bridging between peripheral ICs. The wide I/O count and tolerant MultiVolt inputs make it well suited to industrial control, motor drive, and embedded computing motherboards.

When designing with this device, ensure that I/O bank voltage rails match the connected peripherals; the UFM block is limited to approximately 8 Kbits of non-volatile storage and requires careful write/erase cycle management. Designers should also plan for the JTAG chain when multiple programmable devices share the same boundary-scan bus.

🌐

I/O Voltage Translation and Level Shifting

The EPM240T100C3 with MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V rails on a single 2.5 V / 3.3 V core is an ideal level translator between mixed-voltage peripherals on a modern motherboard. A typical use case bridges a 3.3 V microcontroller to 1.8 V DDR memory or 1.5 V legacy ASICs without external translator ICs, reducing BOM cost by 30-50%. Its non-volatile instant-on configuration means level-shift mappings are available at power-up with zero software loading delay, which is critical for boot sequencing in processor-based designs. The 80 user I/Os provide abundant channels for wide data buses.

🖥️

Bus Multiplexing and Address Decoding

The EPM240T100C3's 192 macrocells and instant-on flash configuration make it ideal for address decoding, chip-select generation, and bus multiplexing in microprocessor and DSP systems. With deterministic pin-to-pin propagation delay (a hallmark of CPLDs versus FPGAs), the device generates clean, glitch-free chip enables well before any software boot, supporting legacy peripherals and memory windows. A common deployment uses the CPLD to arbitrate between an SDRAM controller and an external bus, eliminating the need for 74-series decoder gates and shrinking board area while improving timing margins.

🏭

FPGA / SoC Configuration and Control Logic

The EPM240T100C3 frequently sits next to a larger FPGA or SoC as a configuration supervisor, glue-logic controller, or peripheral manager. Its non-volatile flash memory and JTAG ISP let it store board-revision IDs, MAC addresses, or boot straps in the 8-Kbit User Flash Memory block without an external EEPROM. The CPLD can reset, configure, and monitor an FPGA while exposing status LEDs, fan PWM, and I2C peripherals on 80 MultiVolt-tolerant I/O pins. This design pattern is common in telecom line cards, industrial controllers, and FPGA-based PCIe boards where deterministic startup behavior is mandatory.

🔧

Board-Level Glue Logic Replacement

Engineers replace dozens of 74HC / 74LVC discrete logic gates with a single EPM240T100C3 to consolidate address decoding, parity generation, interrupt prioritization, and reset distribution. The 192 macrocells (240 LEs) absorb roughly 30 to 50 standard SSI / MSI packages, dramatically reducing PCB area, lowering power consumption, and eliminating timing skew between discrete gates. The TQFP-100 footprint fits on existing 74-series land patterns with no board rework, and the Quartus design entry captures schematics that document the logic, easing long-term maintenance.

🏭

Industrial Control and Motor Drive Logic

In industrial automation, the EPM240T100C3 integrates encoder interfaces, PWM generation, fault handling, and safe-torque-off logic in a single deterministic CPLD. With 80 user I/Os and MultiVolt tolerance, the part directly interfaces 3.3 V MCUs and 5 V gate drivers through external level shifters, while the 0C to +85C commercial temperature range suits factory-floor enclosures. Designers benefit from instant-on startup for deterministic motor-brake engagement, plus a non-volatile configuration that survives brown-outs without external boot PROMs or watchdogs.

🌐

Digital Interface Bridging and Protocol Conversion

The EPM240T100C3 bridges legacy parallel buses (e.g., 8/16-bit microcontrollers, SRAM, or ASIC registers) to modern serial interfaces such as SPI, I2C, or UART. Designers implement state machines in Verilog or VHDL, compile with Quartus, and program the CPLD via JTAG to create a custom protocol converter with deterministic latency measured in single-digit nanoseconds. With 80 I/Os and an 8-Kbit UFM, the device can also store device IDs, calibration constants, or configuration scripts alongside the logic - eliminating external EEPROMs in compact embedded designs.

What is the EPM240T100C3?
The EPM240T100C3 is an Intel (formerly Altera) MAX II family CPLD with 192 macrocells, 240 logic elements, and 80 user I/Os in a 100-pin TQFP package. According to the Intel MAX II Device Handbook, it features non-volatile flash configuration, instant-on behavior, and MultiVolt I/O support for 1.5 V / 1.8 V / 2.5 V / 3.3 V interfaces, making it well suited for I/O bridging and glue-logic applications.
How many macrocells and logic elements does the EPM240T100C3 have?
The EPM240T100C3 integrates 192 macrocells organized into Logic Array Blocks, equivalent to 240 logic elements. Per the MAX II datasheet, this is the highest density within the EPM240 sub-family but still the entry point of the MAX II line, sitting below the EPM570 (570 LEs) and EPM1270 (1270 LEs).
What package does the EPM240T100C3 use and what is its pin count?
The EPM240T100C3 is supplied in a 100-pin Thin Quad Flat Pack (TQFP-100) measuring 14x14 mm with a 0.5 mm pitch. The TQFP-100 package gives the part 80 usable user I/O pins, with the remaining pins allocated to power, ground, JTAG, and configuration functions per the Intel datasheet pinout.
What is the operating voltage of the EPM240T100C3?
The EPM240T100C3 operates from a 2.5 V or 3.3 V core supply and supports 1.5 V, 1.8 V, 2.5 V, and 3.3 V MultiVolt I/O banks. This allows direct interfacing with legacy 5 V-tolerant devices through external level shifters and seamless connection to modern low-voltage processors, FPGAs, and ASICs.
Where can I download the EPM240T100C3 datasheet PDF?
The official EPM240T100C3 datasheet is available from Intel (Altera) and authorized distributor archives, including the datasheets.com mirror and the Intel MAX II Device Handbook. Search the manufacturer part number on Intel's content portal or distributor product pages to obtain the latest revision PDF.
What is the price of EPM240T100C3 and is it in stock?
As of 2026-09-12, the EPM240T100C3 lists from approximately USD 6.13 at LCSC for single-unit purchases, with volume pricing dropping toward USD 3.45 at 1,000 pieces. Stock availability is healthy across major distributors including LCSC, DigiKey Marketplace, Octopart-listed suppliers, and several independent brokers, but lead times can extend during supply rebalances.
Where to buy EPM240T100C3 online with short lead time?
To minimize lead time on EPM240T100C3, source from franchised distributors such as LCSC (in-stock at ~USD 6.13 each) or check DigiKey Marketplace and Mouser for current stock. For urgent requirements, contact authorized Intel FPGA distributors and request a quote with a target delivery date.
What is the lead time for EPM240T100C3?
Lead times for EPM240T100C3 are typically 8 to 14 weeks from the manufacturer and 1 to 5 days from authorized distributors when stock is available. As of 2026-09-12, LCSC shows in-stock inventory, which can effectively reduce the lead time to immediate shipment.
EPM240T100C3 vs EPM240T100C5N - which should I choose?
Both parts share the same TQFP-100 footprint, 192 macrocells, and 80 user I/Os, so they are pin-compatible drop-in substitutes. The trailing '3' in C3 indicates a speed grade (faster tPD) while 'C5N' is a slower speed grade with lead-free / Pb-free finish. For new designs, prefer C5N for long-term availability; use C3 only when faster timing closure is required.
What is the best drop-in replacement for EPM240T100C3?
The best drop-in replacement for EPM240T100C3 is the EPM240T100C5N, which shares the same TQFP-100 package, 192 macrocells, 240 logic elements, and 80 user I/Os, and is functionally identical except for speed grade. Both are MAX II family devices and accept the same JTAG programming bitstreams, so board rework is not required.
Can the EPM240M100C5N replace the EPM240T100C3?
No, the EPM240M100C5N uses a 100-pin MBGA package, not the TQFP-100 package of the EPM240T100C3. Although both are 192-macrocell MAX II CPLDs, the BGA footprint requires a different PCB land pattern. Only parts in the EPM240T100 family (TQFP-100) are drop-in compatible with the EPM240T100C3.
Is the EPM240T100C3 suitable for industrial 24 V systems?
The EPM240T100C3 itself does not connect directly to 24 V rails - its I/O banks are limited to 1.5 V to 3.3 V. For industrial 24 V systems, use the CPLD on the low-voltage logic side and add external level shifters, opto-couplers, or isolators between the 24 V field wiring and the CPLD I/O pins. This is the standard practice for industrial control designs using MAX II.
What design software programs the EPM240T100C3?
The EPM240T100C3 is programmed using Intel Quartus Prime (formerly Altera Quartus II) software. Quartus supports Verilog HDL, VHDL, and schematic entry, then synthesizes the design into a JIC or POF bitstream downloadable through a JTAG programmer such as the Altera USB-Blaster or compatible clones.
What is the difference between EPM240T100C3 and EPM240GT100C3?
Both are 100-pin TQFP MAX II CPLDs with 192 macrocells and 80 user I/Os. The EPM240T100C3 is the standard commercial variant, while the EPM240GT100C3 is a lead-free / Pb-free RoHS-compliant version with identical timing. They are functionally drop-in compatible; the G designation indicates green / lead-free finish only.
What are the key specifications of EPM240T100C3 that engineers should know?
The EPM240T100C3 integrates 192 macrocells (240 LEs), provides 80 user I/Os, and supports MultiVolt I/O from 1.5 V to 3.3 V on a 2.5 V / 3.3 V core supply. It comes in a TQFP-100 (14x14 mm) package, offers instant-on non-volatile flash configuration with JTAG ISP, includes an 8-Kbit User Flash Memory block, and operates from 0C to +85C.

선택 가이드

Choose EPM240T100C3 when you need a 192-macrocell MAX II CPLD in the TQFP-100 footprint with the fastest (C3) speed grade, and you do not require lead-free RoHS marking. Choose EPM240GT100C3 for the same C3 timing but with Pb-free / RoHS finish; choose EPM240T100C5N if you can accept slightly slower timing in exchange for longer-term availability and lead-free compliance. Choose EPM240M100C5N only if your PCB has a BGA-100 land pattern - it is not pin-compatible with the TQFP-100. For higher logic density, step up to the EPM570T100 or EPM1270T144 packages; for industrial temperature, select a part with an I-suffix instead of C-suffix.

  • Industry-standard MAX II instant-on architecture (vs EPM240M100C5N (BGA-100 variant))
  • MultiVolt I/O support for 1.5 V / 1.8 V / 2.5 V / 3.3 V interfaces (vs EPM570T100C5N)

설계 노트

The EPM240T100C3 requires both a core supply (VCCINT, 2.5 V or 3.3 V) and per-bank I/O supplies (VCCIO1 through VCCIO4) for MultiVolt operation. Decouple each VCC pin with a 0.1 uF ceramic capacitor as close to the package as possible, and add a bulk 10 uF tantalum or polymer cap on each supply rail. Tie all VCCIO pins in a given bank to the same voltage; mixing voltages within a single bank is not supported by the MAX II architecture and may damage the I/O cells or cause logic errors.

The TQFP-100 (14x14 mm, 0.5 mm pitch) package requires careful PCB layout: use 0.20 mm-wide traces between pins, a 4-layer stack-up with dedicated ground and power planes, and via-in-pad or fan-out vias for clean signal integrity. The MAX II datasheet recommends thermal relief pads on all VCC/GND pins to ease rework, plus a continuous ground plane beneath the device to minimize EMI from the 80 high-speed I/O drivers. Length-match clock and JTAG signals to within 50 mils to avoid setup/hold violations.

Three common pitfalls with the EPM240T100C3: (1) Forgetting that the User Flash Memory (UFM) is only ~8 Kbits and has limited write/erase endurance - do not use it for high-cycle counters. (2) Treating the CPLD as hot-swappable - VCCINT and VCCIO must be ramped together within datasheet limits to avoid latch-up. (3) Confusing the JTAG chain with a microprocessor debug port - the MAX II JTAG pins (TDI/TDO/TMS/TCK) only support boundary scan and ISP, not in-system debugging of external processors.

Although the MAX II is non-fabric-based (instant-on), the 80 LVCMOS I/Os can still produce significant simultaneous switching noise (SSN). Decouple each VCCIO bank with at least 0.1 uF per pin and one bulk cap per bank; place series resistors (22-33 ohm) on high-frequency outputs to dampen reflections. For MultiVolt interfacing, ensure that any 5 V input signal is properly clamped or level-shifted, as the absolute-maximum VCCIO is 3.6 V and over-voltage can permanently damage the I/O cells.
