CABLES

The ISL6271A is a power management integrated circuit (PMIC) designed to provide the low-voltage requirements

for the Bulverde XScale processor. There are three(3) such voltages generated by the PMIC:

1) .85V-1.6V core voltage under DVM or VID control

2) 1.3V PLL voltage, and

3) 1.1V SRAM voltage.

All three outputs are enabled/disabled simultaneously by a common Power Enable (EN) signal from the processor.

Various control and diagnostic functions attend to the orderly sequencing and dynamic control of the PMIC. A

complete functional description of the PMIC can be found in the ISL6271A data sheet (provided).

The ISL6271A evaluation board provides a means to explore and validate the functional capabilities of the ISL6271A

XScale Regulator. The board was designed to have an intuitive layout flow with strapping options to aid in ease of

instrumenting and testing. There is a left-to-right flow of input-to-output, with external inputs coming onto the board

from the left side and the outputs on the right side. LED indicator functions are to the top side of the layout and the

transient load-generator option is in the lower right corner of the board with various strapping options. The core

regulator output can be controlled by either an externally connected I2C interface module (provided) or on-board

static VID switches. Appropriate cabling is provided to make the necessary connections with external testing

equipment.

The following instructions are not intended to effect an exhaustive evaluation of the ISL6271A. They are intended as

a guide into an introductory suite of tests with which the evaluator can gain enough confidence and skill to go deeper

in functional exploration/validation.

Test Equipment Required:

Multi-channel Storage Oscilloscope (with appropriate probes)

Digital Multi-meters (up to 3)

Dual Low-Voltage Adjustable Power Supply

Load - electronic or resistors (0-1A)

PC with available USB port

USB cable

USB/I2C interface module and I2C cable (provided with eval kit)

USB/I2C Software (downloadable from www.intersil.com)
