Hardware enhanced UART, SMBus™, and
-
-
-
enhanced SPI™ serial ports
Four general purpose 16-bit counter/timers
16-Bit programmable counter array (PCA) with three
capture/compare modules
Real time clock mode using PCA or timer and exter-
nal clock source
-
Supply Voltage 2.7 to 3.6 V
-
Typical operating current: 6.4 mA at 25 MHz;
