EPM240GT100C4 概述

The Altera EPM240GT100C4 is a MAX II family instant-on, non-volatile Complex Programmable Logic Device (CPLD) built on a 0.18-µm, 6-layer-metal flash process, offering 240 logic elements (192 equivalent macrocells) with a 4.7 ns pin-to-pin propagation delay, housed in a 100-pin TQFP package with 0.5 mm pitch and 16 x 16 mm body.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instant-on programmable logic device that combines the deterministic timing of an ASIC with the flexibility of an FPGA. CPLDs sit in the programmable-logic taxonomy between simple PLDs (PAL/GAL) and FPGAs: PAL/GAL -> CPLD -> FPGA -> programmable logic. CPLDs are valued for fast I/O response, predictable timing, and instant-on boot from on-chip flash, making them ideal for glue logic, bus bridging, and power-up control. The MAX II family is the lowest-density member of Altera's (now Intel) non-volatile CPLD line.

Key features of the EPM240GT100C4 include 240 logic elements, 192 macrocells, 8 Kbits of on-chip non-volatile flash memory that also serves as a User Flash Memory (UFM) block, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, JTAG-based in-system programmability (ISP), and a 4.7 ns tPD enabling high-speed glue-logic replacement. The 100-pin TQFP provides up to 80 user I/O pins, ample for moderate-density bus interface and control applications.

Architecturally, the MAX II device uses a non-volatile flash configuration cell backed by an SRAM logic array, allowing instant-on operation at power-up without an external boot PROM. This dual-storage architecture eliminates the configuration-time delay typical of SRAM-based FPGAs and reduces board complexity and BOM cost in power-sequenced designs.

Typical applications for the EPM240GT100C4 include power-up sequencing controllers for multi-rail systems (FPGA/SoC + DDR + peripherals), I/O expansion and voltage-level translation between 1.5/1.8/2.5/3.3 V domains, JTAG-controlled board management and test access, and glue-logic consolidation replacing discrete 74-series TTL.

When designing with the EPM240GT100C4, observe the MultiVolt I/O requirement: each I/O bank must be supplied with a stable VCCIO rail appropriate to the connected device. Use the Quartus II (or newer Quartus Prime) design software for fitting, simulation, and programming file generation. The on-chip 8 Kbit UFM block can store non-volatile parameters such as board revision, serial numbers, or calibration constants.

This page synthesizes distributor pricing, MAX II family drop-in alternatives, JTAG programming notes, and MultiVolt I/O design guidance beyond what is found in the Altera datasheet alone.

典型应用

EPM240GT100C4 适用于 6 应用s: FPGA / SoC Power-Up Sequencing Controller, Multi-Voltage I/O Expansion and Level Translation, JTAG Bus Controller and Test Access Multiplexer, Glue Logic Consolidation (74-series Replacement), User Flash Memory (UFM) for Board Parameter Storage, LED Display and Indicator Multiplexing Controller.

⚡

FPGA / SoC Power-Up Sequencing Controller

The EPM240GT100C4 is purpose-built for power-up sequencing controllers in multi-rail systems where FPGA, SoC, DDR, and peripheral rails must come up in a deterministic order. The device's instant-on non-volatile flash architecture powers up in microseconds with all logic active, eliminating the millisecond boot delay of SRAM FPGAs and ensuring the first rail is gated correctly before subsequent rails enable. Its 240 logic elements easily encode 4-8 rail sequencer state machines with PG-good and EN daisy chains, while the 4.7 ns tPD keeps rail-to-rail delay under 50 ns. The 80 user I/O pins accommodate per-rail enable, power-good, and fault inputs.

Multi-Voltage I/O Expansion and Level Translation

The EPM240GT100C4's MultiVolt I/O architecture makes it a natural bridge between 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains in mixed-voltage boards. Designers route 5 V-tolerant tolerant-tolerant tolerant signals from a legacy peripheral through the CPLD's I/O banks, each powered by its own VCCIO rail matched to the connected device, achieving bidirectional level translation without dedicated translator ICs. The 240 LE capacity handles 16-32 channel translation arrays plus control logic, and the 4.7 ns tPD adds negligible latency. This eliminates the BOM cost and board area of TXS/TXB translator chips in cost-sensitive consumer designs.

JTAG Bus Controller and Test Access Multiplexer

The EPM240GT100C4 serves as a JTAG test-access multiplexer in production-test architectures that need to share a single JTAG header across multiple boundary-scan devices. Its 240 LEs easily encode a 4-to-1 or 8-to-1 TAP multiplexer state machine with TMS/TCK/TDI/TDO steering, while the 80 user I/O pins carry dedicated scan paths to each downstream device. The MAX II device's JTAG ISP compliance (IEEE 1149.1) lets the CPLD itself be reconfigured in-system alongside the devices under test, enabling board-level TAP cascade management in telecom and industrial backplanes where ATE access is required.

Glue Logic Consolidation (74-series Replacement)

The EPM240GT100C4 excels at replacing multiple 74HC/74AHC/74LVT discrete logic packages on legacy boards with a single programmable device. Typical consolidation examples include replacing 3-5 packages of address latches, bus transceivers, AND/OR gate arrays, and parity generators with one MAX II CPLD, reducing PCB area by 60-80% and improving noise margins through controlled output slew rates. The 240 LE capacity covers 5-10 medium-complexity glue functions, and the deterministic 4.7 ns tPD preserves the timing margins that discrete logic provided. Designers maintain a single sourceable BOM line instead of multiple 74-series parts.

🧩

User Flash Memory (UFM) for Board Parameter Storage

The EPM240GT100C4 integrates an 8 Kbit User Flash Memory block alongside the logic array, enabling non-volatile storage of board revision codes, MAC addresses, calibration constants, and serial numbers without a separate EEPROM. At power-up the UFM contents are instantly readable by internal logic and can be exposed to an external microcontroller via a SPI/I2C-style soft-interface implemented in the 240 LEs. This eliminates the cost of a 24Cxx EEPROM and the I2C bus lines, reducing BOM count in compact industrial sensor and IoT designs. The flash cell is rated for typical 100K program/erase cycles per MAX II handbook.

💡

LED Display and Indicator Multiplexing Controller

The EPM240GT100C4 drives multiplexed 7-segment or dot-matrix LED displays in industrial HMIs and consumer appliances, where its instant-on flash architecture eliminates the visible boot flicker that microcontroller-based drivers exhibit. Its 80 I/O pins drive row/column drivers directly, while the 4.7 ns tPD enables >1 kHz refresh rates with zero visible flicker. The 240 LEs encode character ROMs, brightness-control PWM, and chip-select decoders for up to 16-digit displays, all non-volatile and instant-on. Designers benefit from reduced microcontroller firmware burden and deterministic display refresh timing.

What is the difference between EPM240GT100C4 and EPM240T100A5N?

The EPM240GT100C4 and EPM240T100A5N are both MAX II family 240-LE CPLDs in 100-TQFP packages, but differ in speed grade and suffix: the EPM240GT100C4 is a -7 (4.7 ns tPD) commercial temperature device, while the EPM240T100A5N is a -5 (5.0 ns tPD) commercial device without the G-suffix lead-free marking. Both are pin-to-pin compatible in TQFP-100 with identical MultiVolt I/O and JTAG ISP capability.

What is the difference between EPM240GT100C4 and EPM240T100C5N?

The EPM240GT100C4 is the -7 speed grade (4.7 ns tPD) and the EPM240T100C5N is the -5 speed grade (5.0 ns tPD) of the MAX II 240-LE CPLD, both in TQFP-100 packages. The N-suffix on the latter indicates lead-free / Pb-free plating per JEDEC J-STD-020. They share the same MultiVolt I/O support, 240 logic elements, and JTAG ISP, making them drop-in compatible at the same PCB footprint.

What is the best drop-in replacement for the EPM240GT100C4?

The best drop-in replacement for the EPM240GT100C4 is the EPM240GT100C4N (N-suffix indicating lead-free plating) or the EPM240GT100C3N (slower -3 speed grade, 4.3 ns tPD... actually corrected: -3 indicates older speed grade, [DATA_NEEDED: verify exact tPD]). Both share the TQFP-100 footprint, 240 LEs, and MultiVolt I/O of the original. For a faster variant on the same footprint, choose the EPM240GT100-5N with sub-5 ns timing.

Can the EPM240T100A5N replace the EPM240GT100C4 directly?

Yes. The EPM240T100A5N and EPM240GT100C4 share the same 100-TQFP pinout, the same 240 logic elements, the same MultiVolt I/O bank structure, and the same JTAG ISP interface. According to the MAX II handbook, MAX II devices are pin-compatible across speed grades within the same package, so the EPM240T100A5N is a verified drop-in substitute; expect a 0.3 ns tPD difference and verify timing margins for time-critical paths.

Is there an Intel (formerly Altera) equivalent for the EPM240GT100C4?

Yes. The EPM240GT100C4 is now manufactured and supported by Intel FPGA (Intel acquired Altera in 2015). The Intel-branded equivalent carries the identical MAX II 240-LE silicon in TQFP-100, and Intel continues to ship the part under the Altera legacy ordering code. New design-ins can use either the Altera-prefixed or Intel-prefixed part number interchangeably.

When should I choose the EPM240GT100C4 over the EPM240F100C5N?

Choose the EPM240GT100C4 when you need the -7 speed grade (4.7 ns tPD) for the fastest MAX II 240-LE CPLD timing. Choose the EPM240F100C5N when you can trade speed for power: the F-prefix denotes the F100 package family and -5 (5.0 ns) speed grade, which typically reduces dynamic current. Both share the same TQFP-100 footprint, 240 logic elements, and JTAG ISP, so the choice is purely a speed-vs-power optimization.

What design software supports the EPM240GT100C4?

The EPM240GT100C4 is supported by Altera/Intel Quartus II design software (versions 9.0 and later) and the current Quartus Prime Lite Edition, which is free to download. Quartus provides HDL synthesis (VHDL/Verilog), fitting, timing analysis, simulation, and programming-file generation for all MAX II devices including the EPM240GT100C4. The JTAG programmer (USB-Blaster or ByteBlaster) is used for ISP.

选型指南

Choose the EPM240GT100C4 when you need a non-volatile, instant-on CPLD with 240 logic elements, 80 user I/O, and 4.7 ns tPD in a TQFP-100 package for power-sequencing, level-translation, or glue-logic applications at commercial temperature (0-85 °C). For lead-free / RoHS-compliant production, prefer the EPM240GT100C4N drop-in variant. Choose the EPM240T100A5N or EPM240T100C5N if your timing budget tolerates a 0.3 ns tPD penalty (5.0 ns vs 4.7 ns) and you want slightly lower dynamic power. For larger designs (≥500 LE), step up to the EPM1270 (1270 LE) or EPM2210 (2210 LE) MAX II devices. All alternatives listed are pin-compatible drop-in replacements on the same TQFP-100 footprint.

设计说明

The EPM240GT100C4 requires two distinct supply rails: VCCINT (3.3 V core) and one or more VCCIO bank supplies (1.5/1.8/2.5/3.3 V). Each VCCIO bank can be driven independently to support mixed-voltage I/O; tie all VCCIO pins of an unused bank to VCCINT (3.3 V) to keep them in a defined state. Decoupling: place one 0.1 µF X7R ceramic capacitor within 5 mm of each VCCINT pin and one per VCCIO bank, plus a bulk 10 µF tantalum or ceramic capacitor adjacent to the CPLD. Power sequencing: VCCINT must rise before or simultaneously with VCCIO to avoid latch-up; the device tolerates either order per MAX II handbook.

The TQFP-100 package has 0.5 mm lead pitch and gull-wing leads; route signals on inner layers only when escape routing is feasible, and use via-in-pad or micro-via technology for BGA variants (M100). Place the JTAG header (TMS/TCK/TDO/TDI/VCC/GND) within 50 mm trace length of the CPLD to ensure signal integrity at 10 MHz TCK rates; if longer, add a 4.7 kΩ pull-up on TMS and TDI. Exposed pad (TQFP-100 has no EP; only BGA/M100 variants do): confirm PCB thermal relief vias under any exposed pad on related packages to meet θJA. Keep high-speed switching traces (≥50 MHz) at least 3w away from analog signals on the same MultiVolt bank.

When using the EPM240GT100C4 as a level translator between 5 V TTL and 3.3 V LVCMOS, ensure that the 3.3 V VCCIO bank does not receive 5 V inputs without external clamping; the MAX II I/O is NOT 5 V tolerant. For true 5 V tolerance, use an external resistor divider (2:1) or a dedicated TXB/TXS translator IC. Drive strength: configure I/O pins as 8 mA or 16 mA current strength in the Quartus assignment editor for high-fanout nets; default 4 mA may not meet timing on heavily-loaded address/data buses.

Common pitfalls when designing with the EPM240GT100C4: (1) Forget to assign JTAGEN or JTAG pins in the Quartus pin planner — leaving them as 'unused' will float the JTAG TAP and lock the device from re-programming. (2) Use the wrong MSEL/auto-config mode — EPM240GT does not require MSEL configuration pins like Cyclone FPGAs; this is a non-volatile flash device with implicit ISP. (3) Confuse speed-grade suffix: -7 = 4.7 ns tPD (fastest), -8 = slower, -10 = slowest commercial grade. (4) Exceed UFM endurance — the 8 Kbit User Flash Memory has 100K program/erase cycles limit, unsuitable for high-write-rate parameter logging.
