EPM240GT100 Обзор
What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that retains its configuration without external memory. Architecturally, CPLDs sit between simple PLDs and FPGAs, offering deterministic timing, fast input-to-output propagation delays (typically 3-5 ns on MAX II), and instant-on behavior. Within the broader taxonomy, CPLDs are part of programmable logic devices, which also include FPGAs, SPLDs, and PALs. The MAX II family represents Altera's lowest-power and lowest-cost CPLD line.
Key features of the EPM240GT100 include up to 80 user I/O pins, a MultiVolt core supporting 1.8V, 2.5V, 3.3V, and 5V I/O standards, 3.3V or 2.5V core operation, JTAG-based IEEE 1149.1 boundary-scan and in-system programmability, and the Altera MultiTrack interconnect architecture. The device is offered in commercial (0C to 85C) and industrial (-40C to 100C) temperature grades.
The EPM240GT100 is widely used as a glue-logic replacement, I/O expander, bus bridge, power-up sequencer, and configuration controller. Its 100-pin TQFP footprint offers the largest I/O count in the EPM240 MAX II sub-family, making it suitable for applications requiring both moderate logic density and high pin count. The MAX II architecture uses LUT-based logic elements with 4-input look-up tables, providing greater flexibility than the macrocell-based MAX 3000/7000 generations.
The EPM240GT100 is supported by Altera's Quartus II design software (legacy) and the newer Quartus Prime Lite Edition. Designers can use schematic, VHDL, or Verilog entry with free licenses. The device is also JTAG-programmable via the ByteBlaster II, USB-Blaster, or compatible third-party programmers.

Типичное применение
EPM240GT100 подходит для 6 применениеs: Glue Logic Replacement, FPGA Configuration & Control, I/O Expander & Level Shifter, Bus Interface Bridge, Power-Up Sequencer & Supervisor, Industrial Control & Logic Consolidation.
Glue Logic Replacement
The EPM240GT100 is widely deployed as a single-chip replacement for multiple 74LS, 74HC, and 74FTTL discrete logic gates, latches, and decoders. With 240 logic elements in a TQFP-100, the device can absorb 30-60 discrete SSI/MSI parts onto one footprint, shrinking PCB area and BOM count. The non-volatile Flash means the circuit powers up in a known state every time - critical for FPGA configuration control, watchdog reset generation, and chip-select decoding. The 5V-tolerant MultiVolt I/O also lets the EPM240GT100 bridge legacy 5V logic to modern 3.3V FPGAs without level shifters.
Рекомендуется
FPGA Configuration & Control
A classic use case is having the EPM240GT100 act as the configuration supervisor for a larger SRAM-based FPGA. The CPLD holds the FPGA's nSTATUS, nCONFIG, and CONF_DONE signals, generates multi-mode configuration clocks, selects between two bitstreams for failsafe updates, and sequences the FPGA's power rails. With 80 user I/Os in TQFP-100, the EPM240GT100 can simultaneously drive configuration, status LEDs, fan PWM, and housekeeping GPIO. Its instant-on behavior guarantees the FPGA is properly held in reset until supplies are stable - a level of robustness discrete logic cannot match.

I/O Expander & Level Shifter
The EPM240GT100's MultiVolt I/O banks support 1.8V, 2.5V, 3.3V, and 5V signaling simultaneously on the same device. Engineers use it as an I/O expander for microcontrollers that lack sufficient GPIO, or as a level shifter between voltage domains. With 80 user I/Os in TQFP-100, the EPM240GT100 can implement 40+ bidirectional level-translated channels. The non-volatile configuration means each board powers up with the correct pin directions and pull-ups already configured, eliminating host-boot-time races seen with I/O expanders on I2C/SPI.
Рекомендуется
Bus Interface Bridge
Designers use the EPM240GT100 to bridge between incompatible bus protocols - parallel memory to serial SPI, 8-bit MCU bus to 16-bit peripheral, or legacy ISA to modern glue logic. The 240 logic elements and 80 I/Os accommodate full 16-bit data plus 24-bit address plus control signal translation on a single chip. The deterministic MAX II timing (no async routing delays) is essential for bus-cycle-accurate bridges. The CPLD's fast tCO and tSU numbers also make it ideal for memory-interleaving controllers in legacy industrial retrofits.
Рекомендуется
Power-Up Sequencer & Supervisor
The EPM240GT100 is ideal for sequencing multiple power rails in networking, server, and industrial systems. With a programmable state machine in 240 logic elements, the CPLD can monitor PG (power-good) inputs and assert EN (enable) outputs in a defined order with programmable delays. The non-volatile Flash means sequencing is hard-coded into the silicon - no firmware to misbehave. The 5V-tolerant inputs can directly monitor legacy analog supervisors, while 3.3V outputs can drive most modern POL regulators' enable pins.
Рекомендуется
Industrial Control & Logic Consolidation
In factory automation and process control, the EPM240GT100 replaces racks of relay logic with a single reprogrammable device. Designers can implement safety interlocks, motor-start sequences, encoder quadrature decoding, PWM generation, and Modbus framing on one TQFP-100 chip. The industrial temperature grade variant (EPM240GT100I5N, -40C to 100C) handles factory floor conditions. The 100-pin TQFP footprint is also easy to hand-prototype or rework on legacy industrial designs where BGA assembly is impractical.

Ключевые отличия
- Non-volatile flash configuration with instant-on behavior (против SRAM-based FPGAs like Cyclone IV)
- MultiVolt I/O supporting 1.8V/2.5V/3.3V/5V in one device (против Discrete 74-series level shifters)
- TQFP-100 footprint provides maximum EPM240 I/O count (против EPM240GM100 (MBGA-100))
Заметки по проектированию
Estimated: The EPM240GT100 with all 80 I/Os toggling at 50 MHz draws approximately 30-50 mA from VCCINT (3.3V) and another 10-20 mA per VCCIO bank. Decouple each VCCINT and VCCIO pin with a 100 nF X7R ceramic placed within 5 mm of the pin, plus a 10 uF bulk capacitor at the supply entry. Use a star-ground topology tying all GND pins to a single solid ground plane under the TQFP-100 footprint. Do not share VCCIO banks between 5V and 3.3V loads - separate them onto independent VCCIO1..VCCIO4 rails so MultiVolt level shifting works correctly.
The TQFP-100 package has 0.5 mm lead pitch with exposed leads on all four sides. Use a 4-layer PCB with a solid ground plane on layer 2 directly under the CPLD to provide a low-impedance return path for the high-edge-rate I/O signals. Route JTAG signals (TDI, TMS, TCK, TDO) as a 4-wire bus with 22-33 ohm source-series termination if the JTAG chain exceeds 100 mm. The EPM240GT100 is a non-volatile flash device - programming times are typically under 1 second via JTAG, but the JTAG chain must be properly terminated at both ends with TCK pull-ups per IEEE 1149.1.
Do not assume the EPM240GT100 (240 LE) is pin-compatible with EPM570T100 (570 LE) or EPM2210F256 (2210 LE) just because the package outline matches - the larger MAX II devices have different JTAG pin assignments and additional power/ground pins. Always check the datasheet's TQFP-100 pinout table before swapping density variants. Also note that the 'GT' suffix denotes TQFP-100, while 'GM' is MBGA-100 and 'GF' is FineLine BGA-100 - the ball/pin counts match but the footprints do not interchange. Industrial-grade (I5N) parts require factory lead time of 6-10 weeks; commercial (C5N) parts typically ship from distributor stock.
Although the EPM240GT100 is a relatively slow CPLD (pin-to-pin delays in the 3-7 ns range), its MultiVolt I/O can drive 5V TTL loads directly when VCCIO is set to 3.3V, with marginal overshoot/undershoot possible. For busses longer than 50 mm or with 8+ loads, add 22-33 ohm series resistors at the source pins to dampen transmission-line ringing. The MAX II MultiTrack interconnect is deterministic - once you compile a design in Quartus, the timing report guarantees those numbers regardless of routing - so external signal-integrity analysis only needs to address the PCB traces, not internal device routing.
