EPM240T100I5N - 240 LE MAX II CPLD, 100-pin TQFP | Intel
MPN: EPM240T100I5N ✓ Hoạt độngEPM240T100I5N Tóm tắt
What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instantly-configurable digital logic IC that replaces discrete glue-logic gates, muxes, and small state machines. CPLDs sit below FPGAs in the programmable-logic taxonomy (CPLD -> programmable logic -> digital IC -> semiconductor), offering deterministic timing, single-chip boot, and lower static power than equivalent FPGA implementations. The MAX II architecture moves the configuration storage into flash so the device behaves like an ASIC at power-up with no external PROM required.
Key features of the EPM240T100I5N include 80 user I/O pins, four I/O banks with independent VCCIO rails, a JTAG-based IEEE 1149.1 boundary-scan / ISP interface, and a MultiVolt core that operates from a single 3.3 V supply while interfacing to mixed-voltage rails. Typical pin-to-pin propagation delays sit around 7 ns and the device supports in-system programmability through the Quartus II / Quartus Prime toolchain.
From an architecture standpoint, the 240 LEs are organized into Logic Array Blocks (LABs), each containing 10 LEs, with interconnect driven by the MultiTrack interconnect fabric. The embedded UFM (8 Kbits) can store user data such as serial numbers, calibration constants, or boot parameters, eliminating a small EEPROM in many designs. The non-volatile flash also removes the boot-time configuration delay common to SRAM-based FPGAs.
Typical applications include I/O expansion and bus bridging between microcontrollers and peripherals, power-sequencer and supervisory logic, glue-logic replacement on industrial PCBs, LED-control drivers, and protocol-bridging glue for I2C/SPI/UART multiplexing. Its flash-backed instant-on behavior is also valued in motor-control and safety-critical industrial systems where deterministic startup is required.
Designers should note that the MAX II family is in mature, long-life supply status; verify long-term availability with the vendor before committing to new high-volume designs, and consider the MAX V family (5M240ZT100C5N) as the pin-compatible next-generation option with a 1.8 V core.

Ứng dụng tiêu biểu
EPM240T100I5N phù hợp cho 7 Áp dụngs: I/O Expansion & Bus Bridging, Power Sequencing & Supervisory Control, Industrial Glue-Logic Replacement, LED Control & Display Drivers, Protocol Bridging (I2C/SPI/UART Multiplexing), Motor Control & Safety-Critical Logic, Legacy System Modernization.
I/O Expansion & Bus Bridging
The EPM240T100I5N is widely used as a glue-logic bridge between microcontrollers and peripherals that require extra I/O pins or voltage-level translation. With 80 user I/Os distributed across four VCCIO banks supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V outputs, the device can interface directly to legacy 5 V-tolerant and modern low-voltage rails without external level shifters. The non-volatile flash-backed instant-on behavior ensures the bridging logic is operational within microseconds of power-up, critical for systems that must respond to bus arbitration immediately. Typical fMAX and pin-to-pin delays around 7 ns make it well suited to glue between an MCU and SDRAM, NAND flash, or parallel peripherals where deterministic timing matters more than raw throughput.

Power Sequencing & Supervisory Control
Power-sequencer and supervisory logic is a canonical CPLD use case, and the EPM240T100I5N is well matched with its flash-backed instant-on and 240 LEs of combinational and sequential logic. The device can monitor multiple power-good rails, drive enable signals to DC-DC converters in a defined sequence, and assert reset to downstream MCUs once all rails are stable. Its 8 Kbits of on-chip user flash memory (UFM) can store non-volatile calibration constants, fault logs, or sequencing configuration - eliminating an external EEPROM in many designs. With -40 °C to +100 °C industrial temperature grade, the part operates reliably in server, telecom, and industrial chassis where supply-rail margins are tight and deterministic power-up is mandatory.

Industrial Glue-Logic Replacement
On industrial PCBs, the EPM240T100I5N replaces dozens of discrete 74-series logic gates, muxes, and small state machines, shrinking BOM cost and PCB area while adding design flexibility. 240 logic elements are sufficient to implement address decoding, chip-select generation, interrupt steering, and PWM modulator logic that would otherwise consume a board's worth of discrete TTL. The 0.18 µm flash process and MultiVolt I/O ensure 3.3 V core operation with mixed-voltage output compatibility, simplifying mixed-rail designs. Industrial -40 °C to +100 °C operation, RoHS compliance, and 80 user I/Os make it a staple in factory automation, PLC I/O modules, and motor-control front-end boards.
Được đề xuất
LED Control & Display Drivers
The EPM240T100I5N serves as a multi-channel LED driver controller in signage, status-indicator panels, and small-format LED matrices. With 80 user I/Os and sub-7 ns propagation delays, the CPLD can drive Charlieplexed LED arrays, generate multiplexed scanning waveforms, and implement PWM dimming at frequencies well above the flicker-fusion threshold. The 8 Kbit UFM can store brightness calibration tables and animation patterns without external memory. The MultiVolt I/O bank architecture allows direct connection to both 5 V LED strings and 3.3 V MCU control logic on the same board. Designers appreciate the deterministic timing of CPLD logic compared with software-driven MCU PWM, which can glitch under interrupt load.

Protocol Bridging (I2C/SPI/UART Multiplexing)
Protocol translation between I2C, SPI, UART, and proprietary serial buses is a common EPM240T100I5N application where the device acts as a hardware mux, splitter, or bit-level translator. The CPLD's deterministic timing and 7 ns typical propagation delay enable bit-banging of fast-mode I2C (400 kHz) and SPI buses up to tens of MHz without jitter. Multiple UART streams can be muxed or demuxed with hardware flow control, freeing the host MCU from polling overhead. The 4-bank MultiVolt I/O architecture lets the same chip bridge a 1.8 V sensor to a 3.3 V MCU to a 5 V actuator in a single part, simplifying mixed-voltage industrial sensor hubs.
Được đề xuất
Motor Control & Safety-Critical Logic
The EPM240T100I5N's flash-backed instant-on and deterministic timing make it a fit for motor-control front-end logic and safety interlocks in industrial drives. The device can implement encoder decoding, hall-sensor conditioning, commutation timing, and hardware safety stop circuits independent of the main MCU, providing a redundant logic layer that operates even before firmware boot completes. Industrial -40 °C to +100 °C ambient rating, 3.3 V core operation, and robust MultiVolt I/O ensure reliable operation in motor-drive enclosures with significant electrical noise. The 8 Kbit UFM can store motor calibration parameters and fault logs for predictive-maintenance designs.
Được đề xuất
Legacy System Modernization
Designers maintaining long-life industrial or military systems use the EPM240T100I5N to modernize aging discrete-logic boards while keeping the same TQFP-100 mechanical footprint. The MAX II family's mature long-life-cycle status and Altera/Intel's continued production support make it a safe choice for designs that must remain in production through 2030 and beyond. Replacing 74LS/74HC logic with a single CPLD reduces PCB area, power consumption, and stocking complexity while enabling last-minute logic changes via JTAG re-programming. Designers planning 5+ year production should consider the MAX V successor (5M240ZT100C5N) as second-source protection, noting the small pin-1 difference.

Ghi chú thiết kế
The EPM240T100I5N requires both a 3.3 V core supply (VCCINT) and one or more I/O bank supplies (VCCIO1 through VCCIO4) for MultiVolt operation. Decouple each VCCINT and VCCIO pin with a 0.1 µF ceramic capacitor placed as close to the pin as possible, plus a bulk 10 µF tantalum or ceramic near the package. Tie all four VCCIO banks to the appropriate level for the attached logic family (1.5 V, 1.8 V, 2.5 V, or 3.3 V) - mixing bank voltages on a single board is supported but each bank must be properly decoupled. Inadequate decoupling on VCCIO banks is the most common cause of JTAG programming failures and signal-integrity glitches.
Use a continuous ground plane under and around the TQFP-100 footprint to provide low-impedance reference for the high-speed I/O signals. The TQFP-100 package has a 0.5 mm pitch - use 0.2 mm-wide traces with 0.2 mm spacing (4-mil design rules) on the fan-out layer and via-in-pad only when necessary to break out the inner-row pins. Avoid running clock or JTAG traces parallel to noisy power-rail tracks; if they must cross, use a 90° crossing to minimize coupling. Place the JTAG header within 50 mm of the device to keep TCK rise times clean.
Do not confuse EPM240T100I5N (industrial, lead-free) with EPM240T100I5 (industrial, non-lead-free) - the latter is for legacy non-RoHS builds and may not be procurable today. Likewise, the 'C5' speed grade is commercial temperature only; never use C5N in industrial designs expecting -40 °C operation. Always check the JTAG chain before programming - a missing or floating TCK/TMS/TDO connection causes confusing 'IDCODE mismatch' errors. Finally, plan for the MAX V successor (5M240ZT100C5N) if your production lifecycle exceeds 5 years, as MAX II is long-life-cycle but not immortal.
Although CPLDs are far more forgiving than FPGAs, the EPM240T100I5N's 80 user I/Os can still generate ground bounce and VCCIO ringing if many pins toggle in the same direction within a few nanoseconds. Spread high-fanout or synchronous signals across multiple VCCIO banks to localize switching current. For outputs longer than 25 mm on FR-4, add a 22-33 Ω series-termination resistor at the driver pin to dampen reflections. Inputs from off-board should be protected with a small RC filter (1 kΩ + 100 pF) to suppress ESD and short glitches.
