What is a CPLD? A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple SPLDs and large FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA -> programmable logic -> digital semiconductor. CPLDs use non-volatile flash or EEPROM configuration cells, giving them instant-on behavior at power-up with no external boot PROM, low static power, deterministic timing, and predictable routing delays. The EPM570GT144C5 specifically belongs to Intel's MAX II G family, which adds high-speed LVDS I/O support on top of the standard MAX II architecture, positioning it for low-cost glue-logic, bus bridging, I/O expansion, and power-sequencing roles.
Key features include 440 macrocells across two logic array blocks, 8.0 Kbits of internal user flash memory for storing user-defined data, MultiVolt I/O supporting 1.5V/1.8V/2.5V/3.3V interfacing from a single 3.3V VCCINT supply, a 1.71V-1.89V VCCIO core range with internal regulator, JTAG-based IEEE Std 1149.1 in-system programmability, and high-speed LVDS I/O at up to 300 Mbps. The 144 TQFP provides 80 general-purpose user I/O pins.
The MAX II G architecture combines a uniform interconnect fabric with Look-Up Table (LUT) based logic elements and a Flash-based configuration block, eliminating the need for an external configuration device. MultiVolt core and I/O structures let each I/O bank operate independently, simplifying mixed-voltage designs.
Primary applications include I/O expansion for microcontrollers and ASICs, bus interface bridging (e.g., SPI-to-parallel, I2C-to-GPIO), power-supply sequencing and supervisory logic, address decoding and glue logic in embedded systems, and high-speed LVDS signal conditioning in industrial control and communications hardware.
When designing, ensure the VCCINT internal regulator is properly bypassed with 0.1uF and 10uF capacitors as shown in the datasheet typical application circuit, and respect MultiVolt I/O bank grouping constraints when assigning mixed-voltage signals.

Ứng dụng tiêu biểu
EPM570GT144C5 phù hợp cho 6 Áp dụngs: Microcontroller I/O Expansion, Bus Interface Bridging, Power Supply Sequencing and Supervisory Logic, Address Decoding and Memory Interfacing, Industrial Control Logic, Communications Equipment Glue Logic.
Microcontroller I/O Expansion
The EPM570GT144C5 expands microcontroller GPIO count by 80 user I/O pins through simple register-mapped logic, making it ideal when an MCU runs out of pins but does not justify a full FPGA. With 570 LEs and 440 macrocells it can implement multiple SPI-to-parallel, I2C-to-GPIO, or shift-register interfaces simultaneously. The 5.4 ns pin-to-pin delay ensures deterministic timing for handshake protocols, and instant-on flash configuration eliminates boot latency. MultiVolt I/O banks support 1.5V/1.8V/2.5V/3.3V peripherals from a single 3.3V supply, simplifying mixed-voltage designs.
Được đề xuất
Bus Interface Bridging
The EPM570GT144C5 bridges mismatched bus protocols such as SPI to parallel, I2C to GPIO, or UART to LVDS, providing glue logic between processors running at different voltages. Its deterministic 5.4 ns tPD guarantees clean setup/hold timing at common bus speeds up to ~150 MHz. MAX II G family LVDS support at 300 Mbps is sufficient for many industrial fieldbus and inter-IC bridging scenarios. The non-volatile flash-based configuration means the bridge is operational within microseconds of power-up, no boot PROM required.
Được đề xuất
Power Supply Sequencing and Supervisory Logic
The EPM570GT144C5 implements power supply sequencers and supervisor logic for multi-rail systems, replacing discrete timing circuits with a single programmable device. Its 80 user I/O pins easily handle 8-12 power rails with enable, fault, and PGOOD signals plus analog monitoring logic via comparators. The deterministic 5.4 ns timing ensures precise rail-to-rail sequencing delays down to the nanosecond. Instant-on flash configuration means the sequencer is operational before any downstream regulator is released, eliminating start-up glitches in processor power trees.
Được đề xuất
Address Decoding and Memory Interfacing
The EPM570GT144C5 provides high-speed address decoding and chip-select logic for processor-to-memory and processor-to-peripheral interfaces, replacing multiple 74-series decoders with one device. With 5.4 ns tPD it can decode addresses well within a single clock cycle at 100 MHz, enabling zero-wait-state memory interfaces. The 570 LEs support multi-bank chip-select logic with multiple address windows per chip, and the JTAG in-system programmability lets you reconfigure memory maps on the fly during development. The 80 I/O pins are sufficient for 4-6 chip selects plus control signal generation.
Được đề xuất
Industrial Control Logic
The EPM570GT144C5 serves as the central logic engine in industrial control boards, implementing deterministic state machines, encoder counters, and PWM generation. Its 440 macrocells handle multiple encoder inputs and motor-control timing logic simultaneously. The MAX II G family LVDS support enables high-noise-immunity communication in factory environments. MultiVolt I/O banks connect directly to 3.3V MCUs and 5V-tolerant sensors through level shifting. The 0C to +85C commercial grade is suitable for enclosed industrial enclosures; -40C to +100C industrial versions are available in the same package under different ordering codes.
Được đề xuất
Communications Equipment Glue Logic
The EPM570GT144C5 implements glue logic in networking and telecom equipment, including line-card interface logic, clock distribution steering, and protocol converters. The 5.4 ns pin-to-pin delay supports deterministic timing for high-speed serial interfaces and bus arbitration logic. MAX II G family LVDS I/O at 300 Mbps handles inter-board communication without external transceivers. The 144-TQFP package offers enough user I/O for line-card designs needing 40-60 signal connections plus JTAG, and the non-volatile instant-on configuration is critical for telecom equipment requiring sub-millisecond power-up.

Ghi chú thiết kế
The EPM570GT144C5 requires a stable 3.3V VCCIO supply for the I/O banks and an internal 1.71V-1.89V VCCINT rail generated by an on-chip voltage regulator from VCCIO. Bypass each VCCIO pin with a 0.1uF ceramic capacitor placed within 5 mm of the pin, and place one bulk 10uF ceramic or tantalum capacitor near the package. According to the MAX II datasheet typical application circuit, the internal regulator needs adequate bulk capacitance to handle inrush during configuration loading. Estimated: total inrush during flash configuration is approximately 50 mA peak for 100-200 us.
Route JTAG signals TCK, TMS, TDI, TDO with 50-ohm controlled impedance and keep traces under 100 mm to avoid signal integrity issues. Place the JTAG header or connector within 50 mm of the device. The four VCCIO bank pins must each be bypassed individually per the MAX II datasheet. MultiVolt bank assignment must be done in the Quartus pin planner before PCB layout to ensure each bank has its own VCCIO rail. Estimated: board area for proper decoupling is approximately 30 mm x 30 mm for the TQFP-144 footprint.
For MAX II G family LVDS operation, route LVDS pairs as 100-ohm differential impedance matched-length within 0.5 mm. Maximum LVDS data rate is 300 Mbps. Use AC-coupling capacitors at the LVDS link boundaries if connecting across connector or backplane interfaces. The remaining GPIO pins default to Schmitt-trigger inputs after power-up; configure unused pins as outputs driving low or as inputs with internal pull-ups enabled to avoid floating-input current draw. Estimated: floating-input leakage per pin is approximately 10 uA.
Common mistakes with the EPM570GT144C5 include: (1) forgetting that each VCCIO bank needs its own bypass capacitor and supply rail, (2) assigning 3.3V and 1.8V signals to the same bank (banks are independent but each bank has one VCCIO voltage), (3) using an external clock on a regular I/O instead of a dedicated CLK pin, which can introduce jitter, and (4) attempting in-system programming without pulling the nCONFIG/nCE pins correctly during reset. Always consult the Quartus II or Quartus Prime device pinout file for the exact bank assignments before PCB layout.
Thông tin tuân thủ
RoHS compliant per distributor listing; SnPb finish (not lead-free) is the standard C5 variant - choose N-suffix variants (e.g. EPM570GT144C5N) for lead-free Pb-free RoHS-compliant finishes. Not AEC-Q100 qualified - choose industrial-grade MAX II variants for automotive.
