مقدمة المنتج:XCR3256XL-10TQG144C مقدمة المنتج

The XCR3256XL-10TQG144C is a 3.3V, 256-macrocell CPLD from Xilinx (now AMD) in the CoolRunner XPLA3 family. It provides 6000 usable gates across 16 function blocks with a maximum pin-to-pin propagation delay of 9.1ns and system frequencies up to 154MHz. The Fast Zero Power (FZP) CMOS technology delivers high performance with ultra-low 18µA typical standby current, making it ideal for power-sensitive designs. The 120 I/O pins are 5V tolerant, enabling mixed-voltage system integration. In-system programming via JTAG supports minimum 1000 program/erase cycles. The device features four global clock networks, input registers, programmable slew rate per output, and a security bit for design protection.

مبدأ العمل:XCR3256XL-10TQG144C مبدأ العمل

The XCR3256XL-10TQG144C uses Xilinx’s CoolRunner XPLA3 architecture based on Fast Zero Power (FZP) CMOS technology. Unlike traditional CPLDs that use sense amplifiers consuming significant static power, the XPLA3 uses a cascade of CMOS gates to implement sum-of-products logic. This approach ensures that only the logic paths being actively switched consume power, resulting in the ultra-low 18µA standby current. Each of the 16 function blocks contains 16 macrocells with a programmable AND array, product term allocation, and a configurable flip-flop. The macrocell can implement combinational or registered logic with optional register bypass, clock enable, and asynchronous preset/clear. Input registers are available on I/O pins for fast setup times in synchronous designs. The four global clock networks distribute low-skew clock signals across the device. The JTAG interface provides in-system programming and boundary scan test capability. The EEPROM-based configuration retains the design without external configuration memory, enabling instant-on operation at power-up.
