EPM240T100C4N Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple glue-logic chips and larger FPGAs. In the broader programmable logic hierarchy, CPLDs are widely used for I/O expansion, bus bridging, power-up sequencing, address decoding, and interface logic glue. Compared with SRAM-based FPGAs, CPLDs do not require a configuration download at every power-up, which makes them ideal for deterministic, instant-on control logic in industrial and consumer systems.
Key features of the EPM240T100C4N include 192 macro cells organized as 240 logic elements, 4.7 ns pin-to-pin logic delay, 247.5 MHz internal performance, 80 user I/O pins, 2.5 V / 3.3 V core operation, MultiVolt I/O support for 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfaces, JTAG boundary-scan test (IEEE 1149.1), and a low standby current typically below 100 µA. It supports vertical migration with other MAX II density points such as the EPM570 and EPM1270 in the same 100-pin TQFP.
The MAX II architecture uses a MultiCore interconnect that routes signals across Logic Array Blocks (LABs) with predictable timing, supporting hot-socketing, open-drain outputs, and bus-hold circuitry. Designers using Quartus II software can target the device through industry-standard VHDL or Verilog HDL with the IEEE Std. 1149.1 JTAG interface.
Typical applications include I/O expansion and bus bridging, address decoding and glue logic in microprocessor/microcontroller systems, LED display driving, industrial control boards, consumer electronics interface management, and protocol translation. Engineers choose this part for instant-on, non-volatile logic that does not need a boot PROM.
Designers should confirm that all VCCIO bank voltages match the connected logic levels and ensure the JTAG chain order is correct in multi-device boards. Decoupling capacitors (0.1 µF + 1 µF) close to each VCC pin are required for clean power-up. Use the Quartus II design software for synthesis, fitting, and programming.

Applications typiques
EPM240T100C4N convient pour 6 applications: Microcontroller I/O Expansion and Bus Bridging, Industrial Control Board Glue Logic, LED Display Driver and Refresh Controller, Address Decoding and Chip-Select Generation, Protocol Translation and Interface Bridging, Power Sequencing and Reset Management.
Microcontroller I/O Expansion and Bus Bridging
The EPM240T100C4N is widely used to expand microcontroller I/O count and bridge between asynchronous buses in embedded designs. With 192 macro cells, 80 user I/O pins, and MultiVolt I/O support for 1.5 V to 3.3 V logic, it interfaces 8-bit or 32-bit MCUs to peripherals such as keypads, LCDs, and sensors. The 4.7 ns tPD handles fast SPI/UART bridges with deterministic timing, while non-volatile instant-on logic removes the boot latency of an FPGA. Place CPLD inputs on MCU-voltage bank (e.g., 3.3 V VCCIO) and outputs on the peripheral-voltage bank to mix logic levels on a single chip.
Recommandé
Industrial Control Board Glue Logic
In PLC and industrial automation boards, the EPM240T100C4N serves as glue logic between MCUs, motor drivers, and signal-conditioning ICs. Its 0.18 µm Flash-based architecture provides deterministic 4.7 ns propagation delay that supports real-time control loops. The 80 user I/O pins and bus-hold circuitry simplify address decoding and chip-select generation, while JTAG 1149.1 boundary-scan enables in-system test during board bring-up. Designers use Quartus II to implement state machines for stepper motor sequencing and safety interlocks, where the CPLD's instant-on behavior is critical at factory-reset events.
Recommandé
LED Display Driver and Refresh Controller
LED matrix and seven-segment display systems benefit from the EPM240T100C4N's high-speed GPIO and predictable timing. The 247.5 MHz maximum internal frequency and 4.7 ns tPD handle multiplexed row/column scanning at refresh rates above 1 kHz without flicker. With 80 I/O pins, the device can drive up to 64-bit RGB matrices or multiple 7-segment digits through external drivers. Open-drain output mode supports common-anode displays, while bus-hold eliminates external pull-up resistors on high-impedance signal lines. Designers route display data through the CPLD, freeing the host MCU for higher-level tasks.
Recommandé
Address Decoding and Chip-Select Generation
The EPM240T100C4N excels at generating chip-select signals for memory and peripheral banks in 8/16/32-bit microprocessor systems. With 4.7 ns propagation delay and 240 logic elements, designers can decode large address spaces and assert multiple chip selects simultaneously with precise timing. This replaces discrete 74HC/HCT logic gates, saving PCB area and improving noise immunity. The CPLD's MultiVolt I/O (1.5 V, 1.8 V, 2.5 V, 3.3 V) makes it compatible with modern MCUs and older 5 V-tolerant peripherals, while JTAG boundary-scan simplifies prototype debugging.
Recommandé
Protocol Translation and Interface Bridging
Designers use the EPM240T100C4N as a low-cost protocol bridge between SPI, I2C, UART, and parallel interfaces. The 192 macro cells fit multiple state machines and shift registers, while the 4.7 ns tPD handles SPI master-mode clock rates above 50 MHz. MultiVolt I/O banks allow 1.8 V sensors to interface with 3.3 V MCUs without external level shifters. The device's in-system programmability means firmware engineers can iterate on protocol logic without changing the PCB layout. This is ideal for legacy system migration and adapter boards.
Recommandé
Power Sequencing and Reset Management
The EPM240T100C4N provides deterministic, instant-on power-up sequencing for multi-rail systems. With Flash-based non-volatile storage, it powers up configured within microseconds, asserting reset signals in the correct order to FPGAs, MCUs, and DDR memory. The 4.7 ns tPD enables precise timing for voltage-monitors and watchdog timers. Designers implement multi-rail sequencing, glitch detection, and power-good signaling without a microcontroller boot dependency. The commercial 0 °C to +85 °C temperature range suits indoor consumer and IT equipment.

Principaux différenciateurs
- C4 speed grade (4.7 ns tPD) - faster than C5 (5.4 ns) variant (vs EPM240T100C5N)
- Industrial temperature variant available in same TQFP-100 (vs EPM240T100I5N)
- Lead-free (RoHS) terminal finish (vs EPM240T100C4 (without 'N' suffix))
Notes de conception
The EPM240T100C4N requires two supply rails: a core VCCINT at 2.5 V or 3.3 V, and up to four independent VCCIO bank supplies supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V (MultiVolt). Decouple each VCCIO and VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, plus a 10 µF bulk capacitor per bank. Power-up sequencing is not required because the device holds I/O in tri-state until configured, but simultaneous ramp of all rails minimizes inrush current.
Use a 4-layer PCB with continuous ground plane under the TQFP-100 footprint for return-path integrity. Route all JTAG signals (TCK, TMS, TDI, TDO) as a matched-length bus with 33 Ω series-termination resistors at the CPLD end to suppress ringing. Keep configuration signals away from fast-switching outputs. The exposed thermal pad is not present on this TQFP package, but adequate copper pour around all 100 pins improves thermal performance for high-utilization designs.
Do not leave unused I/O pins floating - configure them as outputs driving ground or enable the internal weak pull-up via Quartus II. Floating inputs can draw excess current and inject noise into adjacent logic. Also note that the 'C4' speed grade (4.7 ns tPD) and 'C5' (5.4 ns) are NOT interchangeable in timing-critical paths without re-fitting the design - the fitter reports show different delays and may fail timing closure if swapped carelessly.
Group I/O by bank in the Quartus pin planner to match VCCIO domains on the PCB. Place high-speed outputs (clock, JTAG TDO) on dedicated pins away from sensitive analog signals. Maintain 3W spacing between parallel high-frequency traces (e.g., clock and high-speed counters) to reduce crosstalk below 5%. When migrating between MAX II density points (EPM240, EPM570, EPM1270) in the same TQFP-100, verify that the unused macro cells in lower-density parts are not assigned to reserved pin locations.
