EPM240T100C4 概述
What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that sits between simple PAL/GAL devices and high-density FPGAs in the programmable logic hierarchy. CPLDs are characterized by instant-on operation (no external boot PROM required), deterministic timing with predictable routing delays, low standby power, and pin-locked I/O architectures - making them ideal for glue logic, bus interfacing, state-machine control, and I/O expansion. The MAX II family specifically replaces legacy 3.3 V and 5 V CPLDs while cutting power by an order of magnitude.
Key differentiating features of the EPM240T100C4 include 4.7 ns tPD for high-speed decode and interface logic, on-chip user Flash memory (typically 8 Kbits) for storing system parameters without an external EEPROM, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, and JTAG (IEEE 1149.1) boundary-scan support for in-system programming and board-level test.
Technically, the device integrates a Flash-backed Look-Up Table (LUT) architecture with a global interconnect matrix, replacing the classic EEPROM-and-macrocell fabric of older MAX families. This shift lowers static current to milliampere ranges, eliminates the boot delay, and lets the device behave like an 'instant-on' ASIC substitute - programming once and operating forever without intervention.
Typical applications include I/O expansion and level translation between 3.3 V processors and 5 V peripherals, bus decoding for address/data steering in microcontroller systems, glue logic replacement for discrete 74-series gates, LED and 7-segment display drivers, and power-up sequencing controllers in embedded designs.
When designing with this part, reserve one of the four JTAG pins (TCK, TMS, TDI, TDO) for ISP and boundary-scan test. The MultiVolt I/O banks require separate VCCIO rails per bank - verify the bank grouping in the datasheet pinout before assigning mixed-voltage signals.
This page synthesizes real distributor pricing, drop-in same-package alternatives drawn from the MAX II product family, and practical design notes that go beyond the manufacturer datasheet summary.

典型应用
EPM240T100C4 适用于 6 应用s: I/O Expansion and Level Translation, Address/Data Bus Decoding, Glue Logic Replacement, LED and 7-Segment Display Drivers, Power-Up Sequencing Controllers, Industrial Control and Motor Control Logic.
I/O Expansion and Level Translation
The EPM240T100C4 is well suited to I/O expansion and voltage translation between modern 1.8 V or 2.5 V microcontrollers and legacy 3.3 V or 5 V peripherals. Its 80 user I/O pins include MultiVolt banks that natively support 1.5 V, 1.8 V, 2.5 V, and 3.3 V signaling, eliminating external level-shifters and resistors. With a worst-case 4.7 ns pin-to-pin delay, the device can reliably translate high-speed interfaces such as SPI at 50 MHz or parallel busses up to ~100 MHz. Designers typically instantiate bidirectional buffers inside Quartus II and assign pin locations per bank to keep each voltage rail segregated. Compared to discrete 74-series translators, the CPLD approach offers field-upgradable logic without board rework.
推荐
Address/Data Bus Decoding
In microcontroller and embedded-processor systems, the EPM240T100C4 is commonly used as a fast, deterministic address or chip-select decoder. Its 4.7 ns tPD ensures that peripherals see valid chip-select well before the first memory access, eliminating bus-contention glitches that plague slower glue logic. The 192 macro cells support combinational decoding trees of up to ~24 inputs and 80 outputs, enough to map a 24-bit address space. Because the device is non-volatile and instant-on, decoding is available from the very first clock cycle - a critical advantage over SRAM-based FPGAs that require configuration time at power-up. The on-chip 8 Kbit user Flash can store board-revision or calibration constants for the host MCU.
推荐
Glue Logic Replacement
The EPM240T100C4 can replace dozens of discrete 74HC/74AHC logic gates, muxes, and flip-flops on a single chip. With 240 logic elements and 192 macro cells - each containing flip-flops and product-term arrays - the device easily absorbs what would otherwise be 10-30 SSI/MSI packages. This consolidation reduces BOM cost, simplifies PCB layout, and improves noise immunity by shortening critical signal paths. The MAX II family's low standby current (milliampere range) makes it suitable for always-on subsystems, and JTAG ISP lets engineers rewire the logic without re-spinning the board. Quartus II schematic entry keeps the migration path familiar for designers transitioning from legacy TTL/CMOS schematics.
推荐
LED and 7-Segment Display Drivers
The 80 user I/O pins and 4.7 ns tPD make the EPM240T100C4 an excellent display multiplexer and PWM driver for multi-digit 7-segment LED arrays, dot-matrix panels, or RGB LED strips. Each macro cell can drive a constant-current sink with software-defined PWM at refresh rates above 1 kHz, eliminating flicker. The on-chip Flash can store lookup tables for character fonts or gamma curves, freeing the host processor from refresh interrupts. Compared to dedicated LED-driver ICs, the CPLD approach lets designers change the display topology - common-anode to common-cathode, multiplexing scheme, brightness curve - via firmware alone, which is invaluable for short-run product variants.
推荐
Power-Up Sequencing Controllers
Because the EPM240T100C4 is non-volatile and instant-on, it can enforce deterministic power-rail sequencing in multi-voltage systems the moment VIN crosses the POR threshold. Engineers typically instantiate a state machine in VHDL/Verilog that monitors PG (power-good) inputs from each regulator and asserts enable signals in the correct order with defined delays. The 4.7 ns tPD ensures no race conditions between rails, and the 80 I/O pins are enough to sequence 8-12 rails simultaneously. The device's industrial-temperature variant (EPM240T100I4N) extends this role to harsh-environment power architectures.
推荐
Industrial Control and Motor Control Logic
In factory-automation and motor-control designs, the EPM240T100C4 serves as the deterministic logic hub between the MCU, gate drivers, and feedback sensors. Its 4.7 ns tPD closes control loops faster than software interrupt routines, which is critical for trapezoidal commutation and field-oriented control (FOC) of BLDC motors. The MultiVolt I/O banks interface directly to 3.3 V MCUs and 5 V gate drivers, and the 80 I/O pins can read Hall sensors, quadrature encoders, and fault lines concurrently. Choose the EPM240T100I4N variant for ambient temperatures outside the commercial 0-85 °C window. Compared to MCUs with configurable logic units (CLUs), the dedicated CPLD delivers hard real-time response unaffected by firmware or RTOS jitter.

设计说明
The EPM240T100C4 requires two separate power rails: VCCINT (2.5 V or 3.3 V core) and per-bank VCCIO (1.5 V / 1.8 V / 2.5 V / 3.3 V). Decouple each VCCINT pin with a 0.1 µF X7R ceramic placed within 5 mm of the pin, and place a 10 µF bulk tantalum or ceramic near the package. Each VCCIO bank should have its own 0.1 µF + 10 µF pair to suppress switching transients when multiple I/O toggle simultaneously at high frequency.
Route all four JTAG pins (TCK, TMS, TDI, TDO) as a 4-wire daisy chain with TCK shielded by GND on both sides to avoid double-clocking from crosstalk. Provide a JTAG header or test pad accessible on the board for in-system programming. If unused, TMS and TDI should be pulled up to VCCIO via 10 kΩ resistors, and TDO left open per IEEE 1149.1. Keep JTAG traces away from high-frequency switching signals and clock oscillators.
Group I/O assignments by VCCIO bank in the Quartus II pin planner before PCB layout - mixing voltage rails within a bank is not allowed. Place the CPLD close to the connectors and processors it bridges, and route matched-length traces for any bus signals that exceed 50 MHz. Provide at least 4 GND vias under the exposed pad (TQFP-100 has an EP beneath the package) and stitch GND vias around the periphery every 200 mil to minimize ground bounce.
Common pitfalls include (1) floating JTAG pins causing spurious ISP attempts, (2) assigning LVCMOS 1.5 V I/O to a bank powered at 3.3 V (will damage the I/O cells), (3) forgetting to enable the MultiVolt feature in Quartus II fitter settings when mixing voltage rails, and (4) using the C4 speed grade when the design requires C3 timing margin - always run a slow-corner timing analysis at 0.9 × VCCINT and +85 °C before committing to layout.
合规信息
RoHS, REACH, lead-free, halogen-free, and conflict-mineral statuses were not present in the verified web data. The EPM240T100C4 ships in tray packaging per Intel packaging specs. N-variant parts (C3N, A5N, I4N, C5N) feature NiPdAu lead-free plating; non-N variants use standard matte tin - confirm with the manufacturer datasheet for the specific lot if compliance is critical.
