XC2C256-7PQG208C

XC2C256-7PQG208C Description

The XC2C256-7PQG208C is a 256-macrocell CPLD from AMD's CoolRunner II series, designed for high-performance, low-power applications. Operating within a 1.7V to 1.9V internal supply range and a 0°C to 70°C temperature range, this device integrates 16 logic blocks and 6,000 gates, delivering a maximum propagation delay of 6.7 ns. Housed in a 208-pin PQFP package, it offers 173 I/O pins, making it suitable for complex digital designs requiring rapid signal processing and reconfigurability. Though marked as obsolete, it remains relevant for legacy systems due to its RoHS3 compliance and REACH-unaffected status.

XC2C256-7PQG208C Features

• High-Speed Performance: 6.7 ns delay ensures efficient timing-critical applications.
• Low-Power Operation: Optimized for 1.7V–1.9V internal supply, reducing energy consumption.
• In-System Programmability (ISP): Enables field updates without physical removal.
• High I/O Density: 173 I/O pins support extensive interfacing needs.
• Robust Packaging: 208QFP surface-mount package ensures reliability in industrial environments.
