EPM570ZM256C7N - 570 LE MAX II Z CPLD, 256-ball MBGA | Altera
MPN: EPM570ZM256C7N ✓ Hoạt độngEPM570ZM256C7N Tóm tắt
A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic IC that combines multiple PAL-like macro cell blocks connected by a programmable interconnect matrix. Within the broader taxonomy, a CPLD sits below an FPGA in density but offers deterministic timing, lower pin-to-pin delay, and typically flash- or EEPROM-based configuration that boots in microseconds without external boot memory. The MAX II Z variant is the low-power sibling of the MAX II family, retaining the same MultiCore architecture and JTAG-based ISP but trimming dynamic I/O consumption for battery-powered and portable applications.
Key features include 8 Kbits of user flash memory, 5.0 ns pin-to-pin logic delay, MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfacing, JTAG 1149.1 boundary-scan, and an on-chip voltage regulator that allows single-supply operation from a 3.3 V rail. The device supports in-system programmability through Altera's Quartus II design software, and offers built-in joint test action group (JTAG) and standard 4-pin JTAG interfaces. Configuration is stored in on-chip non-volatile memory so the CPLD powers up ready to drive its outputs in under 200 µs.
The MAX II Z architecture pairs a fine-grained look-up table fabric with analog-friendly I/O, and the Z variant specifically targets low dynamic power designs via lower-leakage transistors. The 256-ball MBGA footprint provides high pin density while keeping trace escape manageable on 4-layer FR-4 PCBs. Designers gain the deterministic 5 ns tPD timing that CPLDs are famous for, with no bitstream encryption or boot flash overhead required.
Typical applications include I/O expansion in micro-controller-based systems, power-up sequencing logic, glue logic for ASIC/ASSP replacement, address decoding in embedded boards, and bus-bridging between incompatible voltage domains such as 1.8 V FPGA banks and 3.3 V peripheral buses. The 76 user I/Os comfortably absorb 32-bit address/data muxing plus control signals for legacy microprocessors.
When designing with this device, allocate at least one JTAG header footprint even on prototypes that will not use boundary-scan, because ISP via JTAG is the most reliable field-update path. Use the Quartus II PowerPlay early power estimator before sign-off: the MAX II Z draws dynamic current proportional to toggle rate, and 76 I/Os all switching at 100 MHz can draw over 30 mA just from the I/O ring.

Ứng dụng tiêu biểu
EPM570ZM256C7N phù hợp cho 7 Áp dụngs: Microcontroller I/O Expansion and Bus Muxing, Power-Up Sequencing and Reset Distribution, ASIC/ASSP Replacement and Legacy Interface Bridging, Address Decoding and Chip-Select Generation, Industrial Control and Factory Automation, Portable and Battery-Powered Devices, Telecom and Networking Glue Logic.
Microcontroller I/O Expansion and Bus Muxing
The EPM570ZM256C7N's 76 user I/Os and 570 LEs make it a natural choice for expanding the I/O count or bus width of a host microcontroller that has run out of pins. Placed between the MCU and a 32-bit peripheral bus, the CPLD can demux address lines, generate chip-selects with sub-10 ns latency, and present a wider data window than the MCU alone. The 5.0 ns tPD ensures address-to-CS skew stays well under a 50 MHz memory access cycle, and the on-chip 3.3 V regulator lets the CPLD share the MCU's 3.3 V rail without an extra LDO. JTAG-based ISP allows field upgrades of the mux map without reballing the BGA, which is critical for board revisions after PCB assembly.

Power-Up Sequencing and Reset Distribution
The deterministic 5.0 ns tPD and zero-power MAX II Z architecture suit power-rail sequencing in multi-supply systems such as FPGA + DDR + PHY boards. The CPLD can be powered from the always-on 3.3 V standby rail, monitor PG (power-good) signals from each supply, and release downstream reset lines only after all rails settle. With 76 I/Os the part can sequence 6-8 rails independently while still leaving margin for status LEDs and fault inputs. Compared to a discrete supervisor-IC chain, the CPLD is programmable, JTAG-updatable, and avoids the propagation-delay accumulation that plagues cascaded reset ICs.

ASIC/ASSP Replacement and Legacy Interface Bridging
Many EOL ASSPs in industrial control boards can be emulated by a MAX II Z CPLD programmed as a state machine plus glue logic. The 570-LE capacity comfortably absorbs the equivalent of two small legacy peripheral controllers, and the 5 ns tPD matches the timing of 1980s/90s vintage interface ASICs. The MBGA-256 footprint exposes enough I/Os to bridge between, say, an ISA-bus 5 V host and a 3.3 V ARM peripheral without external buffers. Designers can ship new boards that drop into the original mechanical envelope while keeping the obsolete ASSP firmware behavior intact.

Address Decoding and Chip-Select Generation
In a 32-bit embedded system, the host processor emits a full address bus and needs a unique chip-select for each peripheral region. The EPM570ZM256C7N's AND-OR PLA fabric is purpose-built for this kind of decode: each macro cell combines address bits via product terms and asserts a CS line within 5 ns of address valid. Using 76 I/Os the CPLD can generate up to ~30 chip-selects (each requiring one CS output plus one output-enable), enough for SDRAM, Flash, FPGA config, USB, Ethernet, and several UART peripherals. MultiVolt I/O lets the same CPLD decode both 3.3 V and 5 V address buses simultaneously.
Được đề xuất
Industrial Control and Factory Automation
Factory PLC and motor-control boards demand deterministic logic, long-term supply assurance, and industrial temperature tolerance. The EPM570ZM256C7N's commercial 0 °C to +85 °C range fits indoor cabinet environments, and the MAX II Z zero-power architecture is valuable for solar-powered remote I/O nodes. The 570 LEs handle encoder decoding, PWM blanking, fault interlocks, and Modbus/Profibus glue logic on a single chip. Industrial users appreciate that Altera published PCN1312 adding a TSMC Fab 11 wafer source, extending supply through at least 2030.

Portable and Battery-Powered Devices
The MAX II Z variant of the EPM570ZM256C7N is specifically designed for portable applications where quiescent current matters. While idle, the device draws microamp-level leakage, allowing it to remain powered from a coin-cell or Li-ion battery and still wake peripherals on demand. The 8 Kbits of user flash can store configuration state that survives power-down, useful for handhelds that need to resume instantly on lid open. The 76 I/Os cover display, keypad, sensor, and wireless module interfaces in a typical PDA-class design.
Được đề xuất
Telecom and Networking Glue Logic
In router and switch line-card designs, the EPM570ZM256C7N is used for PHY interface bridging, LED driving, and front-panel management. With MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V, a single CPLD can interface a 1.8 V FPGA to 3.3 V PHYs and 5 V legacy management ICs without level shifters. The 123.5 MHz maximum internal frequency handles 100 Mbit/s Ethernet MDIO and SPI management buses with margin. JTAG ISP enables line-card firmware updates in the field without removing the BGA from production hardware.

Ghi chú thiết kế
The MBGA-256 with 0.5 mm pitch requires 4-layer FR-4 with microvia stackups for escape routing; use 0.8 mm ball-pad diameter and a non-solder-mask-defined (NSMD) pad for best reliability. Place at least eight GND balls distributed across the package perimeter and stitch them with vias to an internal ground plane to provide low-inductance return paths for the high-di/dt I/O switching currents. Decouple each VCCIO bank with a 0.1 µF X7R 0402 ceramic placed within 50 mils of the ball, plus one bulk 4.7 µF tantalum per bank.
The MAX II Z on-chip regulator lets you feed the core from a single 3.3 V rail, but you must still tie VCCINT to the regulator output and not bypass it to an external 1.8 V supply unless the design calls for the multi-rail mode. Per the MAX II handbook, when using the internal regulator leave VCCIO1 at 3.3 V and the regulator generates 1.8 V internally; do not add an external LDO on VCCINT or the two regulators will fight. Estimate dynamic I/O current with the Quartus PowerPlay tool: a worst-case 76-bit bus toggling at 100 MHz draws roughly 30 mA on a 3.3 V VCCIO.
A common mistake is leaving the JTAG TCK pin floating; if TCK is not driven, noise can clock the JTAG TAP and inadvertently trigger ISP or boundary-scan operations. Tie TCK to GND through a 1 kΩ pull-down if the JTAG port is unused, or drive it from the host programmer's TCK pin. Similarly, nSTATUS and nCONFIG need 10 kΩ pull-ups to VCCIO if not actively driven, otherwise the device may not enter user mode at power-on.
Although MAX II Z outputs are slew-rate limited by default, long PCB traces (>2 inches) from clock outputs should still be series-terminated with a 33 Ω resistor to dampen reflections. The MultiVolt I/O receivers tolerate 5 V inputs even when VCCIO is 3.3 V, but the absolute-maximum ratings forbid driving the I/O above 4.6 V when VCCIO is below 3.0 V - consult the MAX II datasheet DC Characteristics table before designing 5 V-to-3.3 V bridges.
Place a 4.7 µF bulk decoupling capacitor within 200 mils of the VCCINT pin pair and a 0.1 µF high-frequency bypass within 50 mils. For multi-bank designs, give each VCCIO bank its own decoupling network - mixing 1.8 V and 3.3 V bank supplies on the same decoupling node injects switching noise through the shared capacitor ESL. The MBGA's central ball row should be reserved for VCCINT and GND alternation to provide a uniform power/ground reference plane beneath the die.
