Communication and control of external devices is facilitated via an  
assortment of digital peripherals such as an enhanced, fully  
configurable SPI bus, an I²C interface, dual UARTs with dedicated  
baud rate generators, three 16-bit timers, 8 PWM controllers each  
with a 16-bit timer, and 2 pulse width counter modules.  
The VRS51L3072 operates from 3.0 to 3.6 volts over the industrial  
temperature range and is available in a QFP-64 package.
