EPM570T144A5N - MAX II CPLD, 570 LE, 144-TQFP | Altera (Intel)
MPN: EPM570T144A5N ✓ פעילEPM570T144A5N סקירה
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs and FPGAs in the programmable logic hierarchy. Unlike SRAM-based FPGAs that require external boot memory, MAX II CPLDs configure themselves in microseconds from internal Flash, providing instant-on behavior at power-up. CPLDs are typically used for glue logic, bus interfacing, power-up sequencing, address decoding, and I/O expansion where deterministic timing and low standby power are required. Within the taxonomy, this device belongs to the chain: MAX II -> MAX family -> CPLD -> programmable logic -> semiconductor IC.
The EPM570T144A5N integrates 440 macro cells distributed across 8 logic array blocks (LABs), with each macro cell containing a programmable AND/OR array and a configurable flip-flop. The device provides 144 user I/O pins (the largest in the MAX II family), 8 Kbits of user Flash memory (UFM), and a JTAG/IEEE 1149.1 interface for in-system programming. Maximum pin-to-pin propagation delay is 5.4 ns, making it well suited for high-speed interface bridging and protocol conversion tasks. Multi-voltage I/O supports interfacing to 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters.
Typical applications include bus interface bridging (e.g., PCI to local bus, microcontroller to parallel port), power-up and power-rail sequencing in multi-supply systems, address decoding and chip-select generation, I/O expansion for microcontrollers and ASSPs, LED display driving, and protocol glue logic in industrial controllers, telecom line cards, and automotive body modules. The automotive temperature grade (denoted by the 'A' suffix) supports -40 °C to +125 °C operation.
Designers should plan for I/O bank grouping to keep voltages compatible on shared banks, and provide adequate decoupling (one 0.1 µF per VCCIO bank is recommended). Quartus II or Quartus Prime design software is required for HDL entry, synthesis, fitting, and programming via the JTAG port using a USB-Blaster or compatible cable.

יישומים טיפוסיים
EPM570T144A5N מתאים עבור 7 יישוםs: Bus Interface Bridging, Power-Up Power-Rail Sequencing, Address Decoding and Chip-Select Generation, I/O Expansion for Microcontrollers, LED Display and Signage Drivers, Automotive Body and Chassis Modules, Industrial Control and Protocol Glue Logic.
Bus Interface Bridging
The EPM570T144A5N is well suited to bridge mismatched bus widths and voltages between microcontrollers, ASICs, and ASSPs. Its 144 user I/O pins can simultaneously drive a 32-bit local bus and a 16-bit peripheral bus, while multi-voltage VCCIO banks (1.5/1.8/2.5/3.3 V) eliminate external level shifters when connecting to legacy 5 V-tolerant or modern 1.8 V cores. The 5.4 ns pin-to-pin delay supports bus cycles up to ~150 MHz, matching common SDRAM and asynchronous SRAM timings. Place the CPLD between the host processor and the peripheral, route JTAG to a header for in-system programming, and use one global clock pin for synchronous bus operations.
מומלץ
Power-Up Power-Rail Sequencing
Deterministic power-rail sequencing is a classic CPLD use case, and the EPM570T144A5N fits this role with 144 I/O pins that can each control a discrete enable line, and a Flash-based instant-on configuration that begins sequencing within microseconds of VCCINT ramp. Each macro cell can implement a programmable delay timer, allowing the designer to chain enables for FPGA cores, ASICs, DDR memory, and analog subsystems. The 5.4 ns propagation delay is more than fast enough for sequencing tasks where delays are typically measured in milliseconds. Tie all unused I/O to defined logic levels to avoid floating pins during the early power-on window, and place 0.1 uF decoupling capacitors adjacent to each VCCIO pin pair.
מומלץ
Address Decoding and Chip-Select Generation
Address decoding for memory maps and chip-select generation is the original use case for the MAX II CPLD family, and the EPM570T144A5N provides 440 macro cells and 144 I/O to decode wide address buses with combinatorial logic. The device supports fast propagation paths that produce chip-select outputs in a single logic level, ensuring zero wait-state access for memory-mapped peripherals. Its non-volatile Flash configuration means the decoded map is available before any CPU boot ROM executes, simplifying system bring-up. Configure the design in Quartus Prime using schematic entry or VHDL, and verify timing with the TimeQuest timing analyzer.
מומלץ
I/O Expansion for Microcontrollers
Many low-pin-count microcontrollers need additional GPIOs for keypads, LCDs, LEDs, or sensor arrays, and the EPM570T144A5N serves as an I/O expander controlled over SPI or I2C by the host MCU. Each macro cell can be configured as an input, output, or bidirectional pin with programmable pull-up, slew rate, and drive strength. The 201.1 MHz maximum internal frequency supports high-speed SPI peripherals up to 50 MHz. Using a CPLD rather than a discrete I/O expander IC keeps the pinout flexible - designers can change the number of GPIOs and pin assignments without respinning the host PCB, by simply re-programming the Flash.
מומלץ
LED Display and Signage Drivers
The EPM570T144A5N's 144 user I/O and 440 macro cells make it suitable for driving multi-segment LED displays, dot-matrix panels, and DMX-controlled signage. Each macro cell can implement a PWM dimming channel, and the 201.1 MHz internal frequency allows smooth 16-bit PWM at refresh rates above 1 kHz with no visible flicker. Multi-voltage I/O supports both 3.3 V logic-level LEDs and 5 V high-brightness strings. Use the on-chip 8 Kbit User Flash Memory (UFM) to store display fonts, animation frames, or gamma correction tables, accessed via the same JTAG port used for configuration.
מומלץ
Automotive Body and Chassis Modules
The 'A' suffix in EPM570T144A5N denotes the automotive temperature grade (-40 °C to +125 °C), qualifying it for body controllers, gateway modules, instrument cluster logic, and chassis domain controllers. With 144 I/O pins, the device can interface directly to CAN/LIN transceivers, discrete switches, relay drivers, and H-bridge motor pre-drivers. Instant-on Flash configuration ensures the module is operational within microseconds of ignition, a hard requirement for airbag and ABS subsystems. AEC-Q100 qualification is typically inherited at the module level when this part is specified into automotive ECU designs.
מומלץ
Industrial Control and Protocol Glue Logic
In industrial PLCs, motion controllers, and process automation modules, the EPM570T144A5N provides the glue logic that ties microcontrollers, FPGAs, ADCs, and motor pre-drivers together. Industrial protocols such as Modbus RTU, RS-485 half-duplex direction control, SPI-to-parallel ADC interfacing, and quadrature encoder decoding all fit easily within 440 macro cells. The automotive temperature grade gives extra margin for cabinet-mounted equipment that may see elevated ambient temperatures near motors or heaters. JTAG-based in-system programming supports field firmware updates via the same programming port used in production.

הערות תכנון
The EPM570T144A5N requires two separate supplies: VCCINT (1.8 V typical) for the core logic and VCCIO (1.5 V, 1.8 V, 2.5 V, or 3.3 V per bank) for the I/O banks. Per the MAX II datasheet power-supply recommendations, place one 0.1 uF decoupling capacitor adjacent to every VCCINT and VCCIO pin pair, plus a bulk 10-47 uF tantalum or ceramic capacitor near each supply rail entry point. Power-on reset (POR) requires both rails to ramp monotonically within datasheet-specified rise times; failure to do so can result in partial Flash configuration and unreliable JTAG access.
The 144-pin TQFP package has 0.5 mm pitch leads and benefits from a 4-layer PCB with a continuous ground plane on the layer directly beneath the device. Route all JTAG signals (TDI, TMS, TCK, TDO) with controlled impedance and keep their total length under 100 mm to avoid signal integrity issues during in-system programming. The exposed thermal pad on the bottom of the TQFP should be soldered to a copper pour connected to GND for best thermal performance.
Multi-voltage I/O banks on the EPM570T144A5N can be configured independently to 1.5/1.8/2.5/3.3 V, allowing direct interface to mixed-voltage buses without external level shifters. However, each bank must use a single VCCIO level - mixing voltages within one bank is not allowed. According to the MAX II datasheet, unused I/O pins should be configured as outputs driving GND or as inputs with the internal weak pull-up enabled to avoid floating-pin supply leakage.
Do not confuse the EPM570 (570 LE, MAX II family) with the older EPM5128, EPM5192, or EPM5064 parts from the classic MAX family - they use different programming files and JTAG instructions, and are not pin-compatible. Also avoid mixing up the EPM570T144A5N (TQFP-144, automotive) with the EPM570F256 (FBGA-256) or EPM570M100 (TQFP-100) variants - the package, pinout, and Quartus pin-assignment files all differ.
Place the JTAG connector or test-points within 50 mm of the EPM570T144A5N package to support USB-Blaster programming in production. Add 4.7 kohm pull-up resistors on TMS, TDI, and nCONFIG per the MAX II JTAG configuration guidelines, and place a 10 kohm pull-up on nSTATUS and CONF_DONE (both are open-drain). For multi-device JTAG chains, daisy-chain TDI to TDO with a 4.7 kohm pull-up on the final TDO.
