EPM240T100C3N Visão geral
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and larger FPGAs in the programmable logic hierarchy (PAL/GAL -> CPLD -> FPGA -> ASIC). Unlike SRAM-based FPGAs, MAX II CPLDs store their configuration in on-chip Flash, so they boot instantly without an external configuration PROM and retain their bitstream through power cycles. They are typically used for glue logic, bus bridging, power-up sequencing, and state-machine replacement where deterministic timing, low power, and instant-on behavior matter more than density.
Key features include 8 Kbits of user Flash memory (UFM), 4.4 ns pin-to-pin logic delay (tPD), 200 MHz internal oscillator, and a MultiVolt I/O interface. The device operates from a single 3.3 V core supply with separate VCCIO banks for mixed-voltage interfacing, consumes only 35 mA typical quiescent current, and supports commercial temperature range (0 °C to +85 °C).
The MAX II architecture combines a continuous interconnect fabric with Logic Array Blocks (LABs), each containing 10 Logic Elements. This non-volatile, instant-on approach eliminates the boot/configuration overhead of SRAM FPGAs, making the EPM240T100C3N a deterministic, low-power solution for high-volume glue-logic applications.
Typical applications include I/O expansion and bus bridging, power-supply sequencing and supervisory logic, LED display driving, industrial control interfaces, and bootloader/reset management for FPGAs and microprocessors. The 80 user I/O pins provide flexible interfacing to parallel buses and digital sensor arrays.
When designing with this device, allocate sufficient VCCIO decoupling (100 nF plus 10 µF bulk) at each bank, and verify JTAG chain integrity before relying on in-system programming. Designers migrating from older MAX 7000-series parts should review the MultiVolt core/I/O split and ensure 3.3 V core rails are present.

Aplicações típicas
EPM240T100C3N é adequado para 6 aplicaçãos: I/O Expansion and Bus Bridging, Power-Supply Sequencing and Supervisory Logic, LED Display Driving and Multiplexing, Industrial Control and Interface Logic, FPGA/Microprocessor Boot and Reset Management, Legacy Logic Replacement and Board Modernization.
I/O Expansion and Bus Bridging
The EPM240T100C3N's 80 user I/Os across four MultiVolt banks and 4.4 ns pin-to-pin delay make it ideal for parallel bus bridging between processors operating at different voltages (e.g., 1.8 V MCU to 3.3 V peripheral). Designers place it between host and target bus, using the LE fabric to map address/data/control signals and the UFM to store bridge configuration constants. Instant-on non-volatile Flash configuration means the bridge is ready before the host CPU boots, simplifying boot sequencing in FPGA/microprocessor systems.
Recomendado
Power-Supply Sequencing and Supervisory Logic
The 4.4 ns deterministic tPD and 8 Kbit UFM let the EPM240T100C3N monitor PG (power-good) signals from multiple DC-DC converters and generate precisely timed enable signals. Unlike microcontrollers, the CPLD is non-volatile and instantly operational at power-up, so supervisory logic runs in microseconds rather than milliseconds. With ~35 mA quiescent current, it adds negligible overhead in always-on power rails, and the JTAG/ISP interface enables in-field updates of the sequencing table without removing the device.
Recomendado
LED Display Driving and Multiplexing
For LED matrix panels, scoreboards, and seven-segment displays, the EPM240T100C3N's 80 user I/Os comfortably drive multiplexed row/column patterns at hundreds of Hz refresh rates with deterministic timing. The 200 MHz internal oscillator and 4.4 ns tPD deliver scan rates that exceed typical LED persistence-of-vision requirements while keeping current draw low. The UFM can store gamma-correction tables and blinking patterns in non-volatile memory, eliminating an external EEPROM in many designs.
Recomendado
Industrial Control and Interface Logic
Industrial PLCs and motor controllers use the EPM240T100C3N to implement deterministic glue logic between sensors, encoders, and a central MCU. With its 3.3 V core and 1.5-3.3 V MultiVolt I/O banks, it directly interfaces 1.8 V MCUs, 2.5 V ADCs, and 3.3 V transceivers without level shifters. The instant-on non-volatile configuration ensures safety interlatches are operational before the application CPU starts, which is essential for IEC 61131-3 PLC designs where deterministic startup is mandated.
Recomendado
FPGA/Microprocessor Boot and Reset Management
The EPM240T100C3N is widely used as a companion CPLD to large SRAM FPGAs, holding the FPGA in reset until all upstream power rails are stable, then releasing it in a controlled sequence. The UFM can store the FPGA's golden configuration image for multi-boot fallback. With 4.4 ns tPD, the reset-release edge can be precisely placed within nanoseconds of the last power-good signal, eliminating the configuration glitches that occur with RC reset circuits.
Recomendado
Legacy Logic Replacement and Board Modernization
Designers modernizing boards built around discrete 74-series glue logic, PAL/GAL devices, or EOL MAX 7000 CPLDs use the EPM240T100C3N as a drop-in functional replacement. The 240 LEs replace tens of 74HC packages, the JTAG/ISP interface eliminates the UV-erase window of older parts, and the 100-pin TQFP matches legacy footprints. Combined with Altera/Intel Quartus II, designers can preserve the original logic while gaining non-volatile instant-on operation and 8 Kbit user Flash storage.

Notas de projeto
Decoupling strategy: place one 0.1 µF ceramic bypass cap adjacent to every VCCINT pin (typically 4 pins distributed around the TQFP) and one 0.1 µF cap next to every VCCIO pin. Add a single 10 µF bulk capacitor on each supply rail within 1 cm of the package. Estimated: peak transient current for 80 I/Os toggling simultaneously can exceed 200 mA on a VCCIO bank; insufficient bulk capacitance causes VCCIO droop that manifests as logic errors at high toggle rates. Designers should not omit the bulk capacitor to save board area.
VCCIO bank sequencing: each VCCIO bank can be powered independently, but the absolute-maximum rating mandates that no VCCIO bank exceed VCCINT by more than 4.0 V during power-up or steady-state operation. Designers often violate this by hot-plugging peripheral cards while VCCINT is still ramping. Solution: add a Schottky diode or load-switch FET on each VCCIO rail to enforce turn-on after VCCINT crosses 2.0 V. Reference the MAX II datasheet pin-connection guidelines for the exact sequencing order of TQFP pin groups.
Layout recommendations for 100-pin TQFP: use 0.4 mm pitch traces with 0.2 mm drill vias for fanout; assign each high-speed clock input (GCLK[0..3]) an adjacent ground via to provide a low-inductance return path. JTAG pins (TDI/TMS/TCK/TDO) should be routed together to minimize skew and isolated from switching signals; pull TMS and TCK to VCCIO through 10 kΩ resistors at the connector to keep the JTAG state machine in reset during board power-up.
Signal integrity for 200 MHz routing: although the MAX II fabric does not operate at 200 MHz continuously, the GCLK inputs accept 200 MHz; route GCLK traces as 50 Ω controlled-impedance with ground reference and keep them shorter than 25 mm to avoid reflections. For mixed-voltage buses, place series resistors (22-33 Ω) within 5 mm of the EPM240T100C3N outputs to dampen ringing when driving high-capacitance loads. Reference Altera AN 447 (Interfacing MAX II Devices with Mixed-Voltage Systems) for detailed guidance.
