EPM240GT100I5 - MAX II CPLD, 240 LE, 80 I/O, TQFP-100 | Intel
MPN: EPM240GT100I5 ✓ Hoạt độngEPM240GT100I5 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on behavior of a PAL/GAL with the density and flexibility of an FPGA-like fabric. Within the broader taxonomy, the EPM240GT100I5 sits in the programmable logic hierarchy as follows: programmable logic device (PLD) -> CPLD -> non-volatile CPLD -> MAX II family -> low-density logic integration (glue-logic class). CPLDs are typically used for I/O expansion, bus bridging, interface logic, power-up sequencing, and "glue logic" between microcontrollers, ASICs, and FPGAs.
Key specifications include a 7.5 ns pin-to-pin propagation delay (tPD), 80 user I/O pins, MultiVolt core supporting 1.8V/2.5V/3.3V/5V I/O standards, an integrated user flash memory (UFM) block of 8 Kbits, and four JTAG-compliant pins for ISP. The device supports vertical migration within the same TQFP-100 footprint to the higher-density EPM570 and EPM1270 MAX II devices, allowing designers to scale logic capacity without changing the PCB.
Typical applications include I/O expansion for microcontrollers and processors, level shifting and voltage translation between mixed-voltage domains, power-sequencing and reset-distribution glue logic, bus-interface bridging (for example, SPI to parallel, I2C to GPIO), and LED / 7-segment display driving in industrial control panels. The instant-on, non-volatile configuration means the device is fully operational within microseconds of power-up - a key advantage over SRAM-based FPGAs.
Designers should pay attention to the I/O bank supply rails (VCCIO must match the driven/received logic level), the JTAG chain ordering when multiple devices share the bus, and the thermal envelope of the TQFP-100 package. The internal pull-up resistors on user I/O pins eliminate the need for external resistors in many bus-interface designs.

Ứng dụng tiêu biểu
EPM240GT100I5 phù hợp cho 6 Áp dụngs: I/O Expansion for Microcontrollers, Bus Bridging and Interface Translation, Power Sequencing and Reset Distribution, Address Decoding and Chip-Select Logic, Industrial Control Panel Logic, LED Display Multiplexing.
I/O Expansion for Microcontrollers
The EPM240GT100I5 adds up to 80 user I/O pins to a host microcontroller or processor whose native GPIO count is insufficient. With 240 logic elements (192 macrocells), the device can implement multiple shift registers, encoder/decoder logic, or matrix-scanned keypads. The instant-on, non-volatile configuration means the expanded I/O is available within microseconds of power-up, with no firmware boot delay. Designers can daisy-chain the JTAG port of the MAX II device with the host MCU to share a single programming header. The MultiVolt VCCIO feature allows the CPLD to interface with 1.8 V, 2.5 V, and 3.3 V MCUs without external level shifters, simplifying mixed-voltage designs.

Bus Bridging and Interface Translation
The EPM240GT100I5 is widely used as a glue-logic bridge between incompatible bus standards - for example SPI to parallel GPIO, I2C to 8-bit data bus, or UART to LVDS. The 7.5 ns tPD supports bus clock rates up to roughly 66 MHz, covering most parallel synchronous buses. Independent VCCIO banks allow the device to receive 1.8 V on one side and transmit 3.3 V on the other, eliminating discrete level shifters. Quartus Prime synthesis with standard library functions simplifies state-machine implementation, and the JTAG ISP capability enables field updates to bridge logic without board rework. The 8-Kbit UFM block can store protocol-configuration parameters that survive power cycles.
Được đề xuất
Power Sequencing and Reset Distribution
In multi-rail systems (FPGA + DDR + analog + I/O), the EPM240GT100I5 implements power-on sequencing, watchdog timers, and reset distribution with deterministic, non-volatile logic. Because the device is fully operational within microseconds of VCCINT stabilization, it can hold downstream rails in reset until all supplies are valid, then release them in a programmable order. The 240-LE capacity is sufficient for several sequenced reset domains plus a watchdog counter. Industrial temperature grade (-40C to +100C) is appropriate for telecom, industrial, and automotive-adjacent equipment. Quartus Prime state-machine design tools simplify development, and JTAG ISP enables post-build sequencing changes.

Address Decoding and Chip-Select Logic
In microprocessor and DSP systems, the EPM240GT100I5 generates chip-select signals, address-strobe qualification, and memory-bank decoding for external peripherals, SRAM, and Flash. The wide input structure supports 24-bit or higher address buses with sub-10 ns decode latency, well within typical memory access budgets. Using CPLD-based decoding instead of discrete 74HC/74FCT logic reduces board area, simplifies trace routing, and allows late-stage design changes via JTAG ISP. The 80 user I/Os accommodate multiple peripheral banks and the UFM can store per-board configuration data such as MAC or serial numbers accessible to the host.

Industrial Control Panel Logic
The EPM240GT100I5 with industrial temperature rating (-40C to +100C) is well suited for factory-automation control panels, PLC I/O modules, and human-machine interface (HMI) backplanes. It can drive LED indicators, scan matrix keypads, debounce mechanical switches, and multiplex 7-segment or LCD displays. The instant-on non-volatile behavior means panel state is always predictable after power-up, a safety-relevant feature. The wide VCCIO range simplifies interfacing with both 24 V-tolerant industrial sensors (via external buffers) and 3.3 V logic controllers. Quartus Prime supports IEC 61131-3-style state diagrams, easing certification of industrial control firmware.
Được đề xuất
LED Display Multiplexing
The EPM240GT100I5 efficiently drives multiplexed LED arrays, dot-matrix displays, and seven-segment indicators by handling row/column scanning, brightness PWM, and character generation in a single non-volatile device. With 80 I/Os and 7.5 ns tPD, it can refresh large arrays at >1 kHz with no visible flicker. The UFM can store custom fonts, animation frames, or brightness profiles without external ROM. Designers benefit from deterministic timing (no boot delay) and JTAG ISP for updating display content in the field. The industrial temperature grade supports outdoor signage and automotive interior displays.

Ghi chú thiết kế
The EPM240GT100I5 requires VCCINT (3.0-3.6 V) for the core and independent VCCIO banks (1.8/2.5/3.3 V) for the four I/O banks. Decouple each VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 5 mm of the package pin, plus a bulk 10 uF tantalum or ceramic capacitor near the device. The internal flash configuration draws surge current during ISP; ensure the 3.3 V regulator can supply at least 100 mA peak. The MultiVolt feature allows direct interfacing with multiple voltage domains, but VCCIO must always be present when VCCINT is powered to prevent I/O latch-up.
Route JTAG signals (TDI, TDO, TMS, TCK) with 4-6 mil traces, keep total length below 50 mm, and add 10 kohm pull-up resistors on TMS and TDI to prevent floating TAP states. Place a 10 kohm pull-down on TCK for clean idle state. For multi-device JTAG chains, include bypass resistors or jumpers so individual devices can be isolated during programming. The TQFP-100 exposed pad (where present) should be soldered to a ground copper pour with thermal vias for heat dissipation, especially in industrial temperature applications.
Do not leave unused I/O pins floating - configure them as outputs driving '0' or as inputs with internal pull-ups enabled via Quartus Prime's 'Unused Pins' setting. Avoid hot-plugging VCCIO while VCCINT is off; this can trigger I/O latch-up. When migrating designs from EPM240 to EPM570 or EPM1270 in the same TQFP-100 package, verify the unused-pin assignments in the Quartus fitter report because higher-density devices have fewer dedicated pins. Do not exceed 3.6 V on VCCINT or 3.6 V on any VCCIO bank.
Estimated: at maximum toggle activity with 80 I/Os switching at 25 MHz and 3.3 V VCCIO, the EPM240GT100I5 dissipates approximately 200-300 mW. With TQFP-100 theta_JA of approximately 50 C/W (standard 4-layer JEDEC test board), the junction temperature rise above ambient is 10-15 C, leaving adequate margin to the +100C industrial maximum. For continuous high-I/O-activity designs in sealed enclosures, add a small copper pour on top of the package to reduce theta_JA by 10-20%. The non-volatile flash process means static power is dominated by I/O leakage, not core switching.
