EPM240T100A5N - 192-Macrocell MAX II CPLD, 100-TQFP | Intel / Altera
MPN: EPM240T100A5N ✓ Hoạt độngEPM240T100A5N Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that uses a sum-of-products architecture with macrocells and a global interconnect to implement glue logic, bus bridging, state machines, and interface translation. Within the broader taxonomy, the CPLD sits below the FPGA in silicon area but above discrete 74-series logic in integration, occupying a unique position for low-power, deterministic, latency-bounded designs. The MAX II family from Altera (now Intel) refined this category by integrating configuration Flash, reducing die size, and cutting static power versus the classic MAX 7000 series.
Key specifications of the EPM240T100A5N include 192 macrocells (equivalent to 240 LEs), a 4.7 ns pin-to-pin logic delay, 80 user I/O pins, and in-system programmability via JTAG (IEEE 1149.1). The device supports hot-socketing, multi-voltage I/O banks, and operation across the commercial 0C to 85C range. Built on a 0.18 µm process, the part is optimized for low static power (~25 mW typical) and zero standby current during configuration.
The MAX II family uses a Flash-backed LUT array feeding macrocells with product-term allocation, which simplifies timing closure compared to SRAM-based FPGAs. Designers benefit from deterministic propagation delays ideal for bus-bridge and protocol-state-machine roles where predictable latency matters more than maximum logic density.
Typical applications include bus decoding and address latching in industrial PLCs, I/O expansion and signal conditioning in embedded systems, I2C/SPI/UART to parallel bus bridges, and power-sequencing logic in telecom backplane hardware. Its instant-on property makes it well suited as a power-rail sequencer or watchdog controller in conjunction with an FPGA host.
When designing with this CPLD, plan for a JTAG header on the PCB to enable in-system programming and on-board debug. Quartus II (or the Intel Quartus Prime Lite edition) is the official toolchain; ensure I/O bank voltage selection matches connected peripherals to avoid contention at power-up.

Ứng dụng tiêu biểu
EPM240T100A5N phù hợp cho 6 Áp dụngs: Bus Decoding and Address Latching in Industrial PLCs, I/O Expansion and Signal Conditioning in Embedded Systems, I2C/SPI/UART to Parallel Bus Bridge, FPGA Power-Rail Sequencing and Watchdog, Telecom Backplane Signal Conditioning, Automotive ECU Logic and Sensor Interface.
Bus Decoding and Address Latching in Industrial PLCs
The EPM240T100A5N's 192 macrocells and 80 user I/O pins give industrial PLC designers enough logic headroom to implement address decoding, chip-select generation, and bus-isolator latching across multiple peripheral buses (PCI, ISA, VME). Its deterministic 4.7 ns tPD keeps address-to-CS latency tight, avoiding bus-cycle stretching on legacy microcontrollers. Placed between the CPU bus and peripheral glue, the CPLD replaces dozens of 74HC-series decoder packages. The 0C to 85C commercial temperature grade covers factory-floor enclosures, while the EPM240T100I5N variant extends to harsher outdoor cabinets. JTAG ISP enables on-board reprogramming via the PLC's service port.

I/O Expansion and Signal Conditioning in Embedded Systems
Embedded SBCs (single-board computers) often lack enough GPIO for user-button matrices, keypad scanning, and LED multiplexing. The EPM240T100A5N attaches to the SPI or I2C bus of an embedded Linux MCU and exposes up to 80 general-purpose I/O lines with programmable debounce, pulse-stretching, and PWM generation. Its 4 multi-voltage I/O banks let it bridge 1.8V, 2.5V, 3.3V, and 5V domains without level shifters. The 201.1 MHz internal frequency supports 10 MHz SPI with comfortable timing margin. The instant-on Flash configuration eliminates the boot delay of SRAM-based FPGA expansions, simplifying watchdog design.

I2C/SPI/UART to Parallel Bus Bridge
When a legacy parallel-bus peripheral must attach to a modern serial-only host (ESP32, Raspberry Pi Pico, etc.), the EPM240T100A5N serves as a compact protocol translator. The CPLD's macrocell array implements state machines for I2C-to-parallel or SPI-to-parallel conversion in roughly 100 macrocells, leaving headroom for additional glue logic. Its 4.7 ns tPD guarantees deterministic acknowledge timing on I2C without bit-stretching issues. The 100-TQFP package is breadboard-friendly for prototypes and reflows cleanly in volume production. JTAG ISP allows firmware updates without desoldering.

FPGA Power-Rail Sequencing and Watchdog
Modern SRAM-based FPGAs require multi-rail power-up sequencing before their I/O become active, and they need external watchdog logic during configuration. The EPM240T100A5N, with its instant-on Flash configuration and zero standby current, sits in front of an FPGA host and sequences its 1.0V, 1.5V, 1.8V, and 3.3V rails via discrete FET drivers. The 4.7 ns pin-to-pin delay keeps PG-to-next-rail delays in the microsecond range. Once the FPGA configures, the CPLD handles the watchdog, error LED, and reset-button debouncing. The part's low static power (~25 mW) keeps it suitable for always-on roles.
Được đề xuất
Telecom Backplane Signal Conditioning
In telecom backplanes carrying E1/T1 or Ethernet PHY signals, the EPM240T100A5N acts as a programmable line interface, providing per-channel signal inversion, bus-width conversion, and clock-domain crossing between the line card and the switch fabric ASIC. Its 80 user I/O comfortably handle an octal E1 framer's bit-clock, data, and framing pulses. The multi-voltage I/O banks let it interface 1.8V PHY logic on one side and 3.3V switch fabric on the other. Deterministic timing keeps jitter budget tight for telecom-grade SERDES compatibility. JTAG boundary-scan supports manufacturing test.
Được đề xuất
Automotive ECU Logic and Sensor Interface
Automotive ECUs for body controllers, instrument clusters, and sensor-fusion modules benefit from the EPM240T100A5N's AEC-Q100-qualifiable MAX II family heritage, deterministic timing, and 80 I/O count. The CPLD aggregates analog-multiplexed sensor inputs, drives PWM outputs for LED matrices, and implements CAN-bus fault-recovery state machines in macrocell logic. Compared to a small FPGA, the MAX II offers instant-on behavior needed for fail-operational modes after a watchdog reset. Vertical migration within MAX II allows scaling up to EPM570 or EPM1270 for richer ECU designs.

Ghi chú thiết kế
The EPM240T100A5N requires a stable 2.5V or 3.3V VCCINT core supply and per-bank VCCIO supplies (1.5V/1.8V/2.5V/3.3V depending on the attached logic). Decouple each VCCIO and VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 uF tantalum near the package. Power sequencing between VCCINT and VCCIO is not required by the MAX II family, but simultaneous ramp is recommended to avoid I/O driving into a partially biased output stage.
Route JTAG signals (TCK, TMS, TDI, TDO) away from clock and switching power traces to avoid pattern-dependent glitches during in-system programming. Place a 4.7 kohm pull-up on TCK and TMS per the IEEE 1149.1 recommendation; if the JTAG port is shared with other devices, follow daisy-chain or star topology guidelines from the MAX II handbook. Provide a 10-pin 0.1-inch JTAG header on the PCB edge for production programming.
Assign bank voltages to match adjacent logic families: bank 1 to 3.3V peripherals, bank 2 to 1.8V DDR controller, bank 3 to 5V-tolerant inputs (using open-drain outputs), and bank 4 to 2.5V legacy bus. Avoid mixing an LVDS pair across banks since MAX II does not support true LVDS - only emulated LVDS with external resistor networks. Keep high-speed outputs short (<25 mm) to limit ringing on the 100-TQFP lead frame.
Do not confuse the EPM240T100A5N with the EPM240GT100A5N - the GT suffix denotes a different family (MAX II G) with enhanced I/O features and slightly different timing. Verify ordering codes against the Altera/Intel MAX II datasheet before procurement. Also note that the A5 speed grade is the slowest in the MAX II lineup; designs requiring higher performance should choose C5 or C4 grades where available.
When the EPM240T100A5N drives buses above 50 MHz, add 22 ohm series damping resistors at the CPLD outputs to control edge rates and minimize reflections on long PCB traces. For clock fanout above 4 loads, insert a clock buffer IC instead of daisy-chaining the CPLD outputs to preserve duty-cycle integrity. On multi-board backplanes, add source termination at the CPLD and keep stub lengths below 1/10 of the signal rise time.
Thông tin tuân thủ
