EPM7160EQC160-15 | Altera CPLD | 15ns Delay | 160 Macrocells | 5V Logic Device
The EPM7160EQC160-15 represents Altera's (now Intel) high-performance Complex Programmable Logic Device (CPLD) solution, engineered for demanding digital logic applications. This electrically erasable PLD (EE PLD) delivers exceptional 15ns propagation delay performance while operating at standard 5V logic levels (4.75V-5.25V range). With its 160-macrocell architecture providing 3,200 equivalent gates and 104 configurable I/O pins, this device offers remarkable logic density in a compact 160-pin PQFP package. The EPM7160EQC160-15 maintains reliable operation across commercial temperature ranges (0 C to 70 C), making it suitable for both prototyping and production environments where consistent performance is critical.
Designed for system-level integration, the EPM7160EQC160-15 features 10 flexible logic blocks interconnected through Altera's proven programmable interconnect array (PIA) technology. The device supports in-system programmability (ISP) through industry-standard programming tools, enabling field upgrades and design iterations. Its surface-mount PQFP-160 package (28 28mm body size) optimizes board space utilization while providing robust mechanical stability. The CPLD's deterministic timing characteristics and pin-to-pin delays of just 15ns make it particularly valuable for applications requiring precise timing control, such as bus interfacing, state machine implementation, and glue logic consolidation.
The EPM7160EQC160-15 excels in power management with typical standby current below 100 A, while delivering up to 125MHz performance. Each macrocell can be individually configured for sequential or combinatorial logic operations with programmable clocking options. The device incorporates advanced features like programmable slew rate control (for EMI reduction), input/output register capability, and global clear/preset functions. Security features include a programmable security bit that prevents unauthorized readback of configured designs, protecting intellectual property in sensitive applications.
This Altera CPLD finds extensive application across multiple industries including industrial automation (PLC control, motor drives), telecommunications (signal processing, protocol conversion), automotive electronics (sensor interfacing, dashboard controls), medical devices (patient monitoring systems), and consumer electronics (display controllers, gaming hardware). Its ability to replace dozens of discrete logic ICs makes it particularly valuable for board space reduction and BOM consolidation. The device is commonly used for implementing address decoders, complex state machines, data path control logic, and interface bridging between processors and peripherals.
Designers benefit from comprehensive development support through Quartus II and MAX+PLUS II design software, which provides schematic entry, VHDL/Verilog support, and sophisticated timing analysis tools. The EPM7160EQC160-15 maintains backward compatibility with earlier MAX 7000 series devices, allowing easy migration of legacy designs. With its combination of performance, density, and reliability, this CPLD continues to serve as a versatile solution for digital system implementation, particularly in applications requiring medium complexity logic with deterministic timing characteristics and non-volatile configuration storage.
