On-chip dynamic power control minimizes package power

dissipation in current mode. This reduced power dissipation

is achieved by regulating the voltage on the output driver from

7.4 V to 29.5 V using a dc-to-dc boost converter optimized for

minimum on-chip power dissipation.

The

at clock rates of up to 30 MHz and is compatible with standard

SPI, QSPI™, MICROWIRE®, DSP, and microcontroller interface

standards. The serial interface also features optional CRC-8 packet

error checking, as well as a watchdog timer that monitors activity

on the interface.
