AMD SK-CRII-L-G

Overview

SK-CRII-L-G from Xilinx is a CoolRunner-II CPLD Starter Kit evaluation platform centered on the XC2C256-TQ144 device, featuring high-speed USB programming, real-time current/temperature monitoring via multi-channel sigma-delta A/D, and a 16×2 LCD display for rapid low-power CPLD prototyping in remote monitoring and wireless interfacing applications.

For engineers reviewing the SK-CRII-L-G datasheet, pinout, applications, or equivalent options, this kit delivers out-of-the-box evaluation of 1.8 V ultra-low-power CPLD functionality-including DataGATE™-enabled dynamic power gating, CoolCLOCK™ clock management, and I/O bank current measurement-critical for battery-constrained handheld and industrial edge devices.

Technical Context

The SK-CRII-L-G evaluation board implements the XC2C256 CPLD in TQ144 package with dual 1.8 V I/O banks and core voltage regulation. It integrates a 16-bit sigma-delta ADC to monitor real-time current draw per I/O bank and core, plus ambient temperature, updating measurements at 2 Hz per channel through USB to the CoolRunner-II Utility Window.

It supports SPI ROM expansion for memory interfacing and includes dedicated hardware for synchronous communication evaluation, chip-to-chip integration testing, and low-power system interfacing-enabling direct validation of DataGATE™-driven power state transitions and CoolCLOCK™-managed clock domain isolation.

FAQ

What is the primary CPLD device mounted on the SK-CRII-L-G evaluation board?

The SK-CRII-L-G evaluation board features the XC2C256-TQ144 CPLD-a 256-macrocell, 1.8 V device with dual I/O banks and integrated DataGATE™ capability. This specific device enables real-time power gating and low-quiescent-current operation critical to the SK-CRII-L-G's function as a low-power evaluation platform.

Does the SK-CRII-L-G support battery-powered operation, and how is it implemented?

Yes, the SK-CRII-L-G includes a 9 V battery connector that allows fully standalone operation without USB power. This enables field-deployable validation of the XC2C256's standby current (as low as 28 µW) and dynamic power behavior under real-world portable conditions-key for evaluating SK-CRII-L-G in handheld or remote monitoring use cases.

How does the CoolRunner-II Utility Window interact with the SK-CRII-L-G hardware?

The CoolRunner-II Utility Window receives telemetry data from the SK-CRII-L-G's on-board 16-bit sigma-delta ADC, displaying real-time current consumption for the CPLD core and each I/O bank, plus ambient temperature, updated at 2 Hz per channel. This direct feedback loop is integral to SK-CRII-L-G's value in quantifying low-power design decisions.

What software tools ship with the SK-CRII-L-G for CPLD development?

The SK-CRII-L-G ships with Xilinx ISE WebPack Software and a Resource CD containing reference designs, QuickStart Guide, and documentation. These tools enable full synthesis, place-and-route, and programming of the XC2C256 device onboard the SK-CRII-L-G-providing a complete out-of-the-box development environment.

Can the SK-CRII-L-G be used to evaluate DataGATE™ functionality, and how?

Yes-the SK-CRII-L-G directly supports DataGATE™ evaluation via its real-time current monitoring architecture. By toggling user-defined logic paths in the XC2C256 device and observing instantaneous current changes in the Utility Window, engineers can validate dynamic power gating behavior, confirming up to 4× battery life extension as specified for the SK-CRII-L-G platform.
