EPM570GM256I5N - 570 LE MAX II CPLD, 256-MBGA | Intel (Altera)
MPN: EPM570GM256I5N ✓ Hoạt độngEPM570GM256I5N Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile, flash-based programmable logic device that occupies the architectural middle ground between small SPLDs and large FPGAs. It belongs to the broader Programmable Logic Device (PLD) family, providing instant-on behavior (no boot time), deterministic timing, and high drive strength on every pin. Within the system hierarchy, CPLDs sit alongside ASICs, FPGAs, and microcontrollers in the digital logic IC category, typically used as glue logic, bus bridges, I/O expanders, and power-up sequencers.
Key features include MultiVolt core support (1.71 V to 1.89 V internal supply with mixed-voltage I/O banks), an embedded User Flash Memory (UFM) block of 8 Kbits for non-volatile data storage, and enhanced in-system programmability. The device also offers JTAG boundary-scan (IEEE 1149.1), 4-input look-up tables, and robust 3.3 V PCI-compatible I/O. Compared with traditional EEPROM-based CPLDs, the flash-based MAX II architecture reduces standby current to approximately 50 µA per macrocell and provides instant-on configuration in under 1 ms.
Typical applications include I/O expansion for microcontrollers, bus interface bridging (e.g., parallel-to-parallel voltage translation), power-up and power-sequencing controllers, board-level glue logic replacement, and configuration management for downstream FPGAs. The 256-MBGA package enables dense board layouts while exposing 160 user I/Os - sufficient to replace several discrete logic ICs.
When designing with this device, ensure the JTAG chain accommodates the device ID and that decoupling follows the MAX II handbook recommendation of 0.1 µF and 10 µF capacitors near each supply pin. Programming files should be generated with Quartus II or the latest Intel Quartus Prime Lite Edition, and unused pins should be configured as outputs driving ground for noise immunity. The instant-on non-volatile flash makes it ideal for safety-critical applications where deterministic power-up behavior is mandatory.

Ứng dụng tiêu biểu
EPM570GM256I5N phù hợp cho 6 Áp dụngs: Microcontroller I/O Expansion, Bus Interface Bridging, Power-Up and Power-Sequencing Controller, FPGA Configuration Manager, Board-Level Glue Logic Replacement, Legacy Industrial Control Retrofit.
Microcontroller I/O Expansion
The EPM570GM256I5N is widely used to expand the limited I/O count of 8-bit and 32-bit microcontrollers. With 160 user I/Os, 570 logic elements, and 5.4 ns propagation delay, it can decode address lines to drive peripheral chip-selects, multiplex additional key-scan or LED-scan matrices, and provide deterministic timing for real-time control loops. Unlike an FPGA, it powers up instantly without a boot PROM, so I/O signals are valid within microseconds of VCC ramp. MultiVolt I/O banks (1.5 V to 5.0 V) allow the CPLD to bridge between a 1.8 V MCU and 3.3 V peripherals without external level shifters, saving board area and BOM cost in industrial controllers and consumer appliances.
Được đề xuất
Bus Interface Bridging
The EPM570GM256I5N excels as a glue-logic bridge between mismatched bus protocols, such as parallel 16-bit MCU buses to 32-bit peripherals, or asynchronous SRAM to high-speed ADC/DAC interfaces. Its 440 macrocells and 5.4 ns tpd support pipelined address-latch, chip-select, and wait-state generation at clock rates beyond 150 MHz. The device's 3.3 V PCI-compatible I/O cells drive backplanes directly, while MultiVolt I/O banks allow direct connection to 1.8 V ASICs. In a typical application, the CPLD bridges a 16-bit MPU bus to a 32-bit DDR memory controller, generating burst-mode control signals with deterministic timing that ASICs cannot match.
Được đề xuất
Power-Up and Power-Sequencing Controller
Because the EPM570GM256I5N is non-volatile flash-based, it powers up with all outputs defined in less than 1 ms, making it ideal for power-rail sequencing in multi-rail systems. Engineers commonly program it to assert enable signals to switching regulators in a defined order, monitor PG (power-good) feedback, and hold downstream loads in reset until all rails are stable. The 5.4 ns propagation delay ensures sub-microsecond response to fault conditions, and the industrial -40 C to +100 C temperature range supports deployment in outdoor telecom, industrial automation, and automotive-grade environments where supply integrity is critical.
Được đề xuất
FPGA Configuration Manager
The EPM570GM256I5N is frequently used as a companion configuration manager for FPGAs that require multiple bitstreams, golden-image fallback, or field updates. The CPLD's embedded 8 Kbit User Flash Memory can store one or two compressed FPGA bitstreams, while its JTAG port chains to the FPGA for programming. With 5.4 ns timing and 160 I/Os, the device can route FPGA configuration pins, mode-select jumpers, and watchdog signals, and load the FPGA via SelectMAP or SPI in well under 100 ms. This is a common pattern in defense, aerospace, and industrial designs where deterministic FPGA bring-up is mandatory.
Được đề xuất
Board-Level Glue Logic Replacement
A single EPM570GM256I5N can replace dozens of 74-series TTL or CMOS discrete logic packages (gates, muxes, latches, decoders, counters) with a single 11x11 mm BGA, dramatically reducing PCB area and BOM count. With 570 LEs and 440 macrocells, the device can absorb entire legacy schematics while adding JTAG-reprogrammability that simplifies board revisions. The 5.4 ns tpd matches or beats standard 74F logic, and the industrial temperature range covers factory-floor, automotive, and outdoor installations. This consolidation also reduces EMI by eliminating long point-to-point discrete-logic traces.
Được đề xuất
Legacy Industrial Control Retrofit
The EPM570GM256I5N's instant-on, deterministic behavior and industrial temperature rating make it a common retrofit for legacy PLC, CNC, and motor-drive controllers that must keep operating for decades. Engineers use it to add modern interfaces (SPI to legacy parallel buses, USB to RS-232 emulation) without redesigning the host board. The flash-based non-volatile configuration survives 20+ year storage and is JTAG-reprogrammable in the field via the test header. Its 5.4 ns tpd is adequate for step/direction pulse trains up to ~50 MHz in servo drive retrofits.

Ghi chú thiết kế
The MAX II CPLD core requires 1.71-1.89 V (VCCINT) plus four independent VCCIO bank supplies (1.5/1.8/2.5/3.3 V). Place a 0.1 uF ceramic decoupling capacitor within 3 mm of every VCCINT pin and a 10 uF bulk tantalum or ceramic capacitor near each VCCIO bank. Total inrush current during ISP programming may briefly reach 200 mA; ensure the regulator has 500 mA headroom. For MultiVolt operation, unused I/O banks should still be powered (tie VCCIO to the lowest used voltage) to keep I/O cells in a defined state.
The 256-MBGA package uses a 1.0 mm ball pitch on an 11x11 mm substrate. Escape routing between balls requires 4 routing layers minimum with 0.1 mm trace/space; a 6-layer stack-up is recommended. Place a continuous ground plane on layer 2 directly beneath the BGA to provide a low-impedance return path for the high-edge-rate JTAG and configuration signals. Avoid running clock traces between BGA balls - route them on outer layers only after escape.
Keep JTAG signals (TCK, TMS, TDI, TDO) short (< 50 mm) and route them on the same layer to avoid stub reflections. Add a 10 kohm pull-up to TCK, TMS, and TDI per IEEE 1149.1. Series-terminate TCK with 22-33 ohm if the trace exceeds 25 mm or if multiple devices share the JTAG chain. Place a guard ring of ground vias around the BGA to reduce EMI coupling into adjacent analog sections.
Do not leave nCONFIG floating - tie it to VCCIO through a 10 kohm resistor to ensure the device enters user mode at power-up. The CONF_DONE and nSTATUS pins are open-drain during configuration and require external 10 kohm pull-ups to VCCIO. When programming in-system via JTAG, ensure the JTAG chain order in Quartus matches the physical daisy-chain (TDO of one device to TDI of the next); reversed chains will fail silently with chain-checker errors.
The 5.4 ns tpd and 160 MHz internal performance place the MAX II in the moderate-speed logic tier. Series-terminate outputs that drive traces longer than 50 mm or that fan out to more than 4 loads, using 22-33 ohm resistors at the source. For 3.3 V PCI signaling, the I/O banks must be configured for 3.3 V PCI compliance in Quartus; default LVTTL settings will not meet PCI rise/fall requirements. Avoid placing the CPLD near switching power inductors - the 8 Kbit UFM block is sensitive to EMI above 100 MHz.
