EPM570ZF256C7N: High-Performance Altera CPLD | 570LE, 440 Macrocells, 160 I/O
The EPM570ZF256C7N from Altera (now Intel) represents the pinnacle of Complex Programmable Logic Device (CPLD) technology, combining high-speed processing with exceptional energy efficiency. This 1.8V device features 570 logic elements and 440 macrocells organized in a maximally efficient architecture, delivering 9ns propagation delays for real-time performance. The 256-TFBGA package (11x11mm) integrates 160 I/O pins with advanced signal integrity, while its in-system programmability enables field upgrades without hardware changes. With an operating range of 0 C to 85 C and industrial-grade reliability, this CPLD is engineered for 24/7 operation in mission-critical systems.
At the core of the EPM570ZF256C7N lies Altera's proven MAX II architecture, featuring non-volatile Flash-based configuration with instant-on capability. The device consumes 50% less power than competing CPLDs while delivering 3x the density-per-watt. Its 1.71V to 1.89V internal voltage regulator maintains stable operation across power fluctuations, with <1 A standby current. The integrated user Flash memory (8,192 bits) enables data storage without external EEPROMs. Designers benefit from Quartus II software compatibility, including advanced timing analysis and industry-standard VHDL/Verilog support.
This CPLD excels in protocol bridging applications with dedicated PLLs for clock management and 8 global clock networks. The macrocells support registered or combinatorial operation with individual clock/reset controls. Advanced I/O banks feature programmable slew rates (2.5V to 3.3V tolerant) and bus-hold circuitry. Security features include 128-bit AES encryption for IP protection and tamper-resistant configuration. Reliability metrics include >10,000 programming cycles and 20-year configuration retention.
The EPM570ZF256C7N powers next-generation designs across industries: Industrial (PLC I/O expansion, motor control), Communications (Ethernet switching, PCIe bridging), Medical (portable diagnostics, imaging interfaces), and Automotive (sensor fusion, infotainment). Its deterministic timing eliminates processor bottlenecks in control applications, while the massive parallel processing capability handles high-speed data path tasks. Designers replace multiple discrete ICs with this single-chip solution, reducing BOM costs by up to 40%.
Compared to FPGAs, the EPM570ZF256C7N offers superior reliability for state machines and glue logic with zero boot time. Hardware engineers appreciate the simplified PCB layout using 1.8V core voltage, while software teams leverage the mature Quartus toolchain. Available in commercial (0 C to 85 C) and industrial (-40 C to 100 C) variants, this CPLD is RoHS 6/6 compliant and backed by Altera's 10-year longevity commitment. Reference designs include JTAG debug interfaces and power sequencing circuits for rapid deployment.
