There is an increasing number of applications and regulations demanding lower power and energy saving modes, and the C8051F9xx is a perfect fit to meet these needs. The C8051F9xx product family is specifically designed to increase battery lifetime, which is the number one requirement for most battery powered applications. This family has a very low active mode current consumption sleep mode, which saves power when the devide is sleeping.The sleep mode is typically the main operating mode of battery powered applications. Wtih its high speed core, advanced analog peripherals, smaller memory size and compact package, the C0851F912 is ideal for volume applications requiring precision analog and low power. As an example, the C8051F912 is a perfit fit for sensor applications that require tiny footprint, ultra-low power and a high resolution ADC to sample the sensor outputs. In addition, the C8051F912, which includes a high resolution 12-bit ADC, DC/DC converter, multiple comparators, internal oscillators, temperature sensor, and 6-bit iDAC, integrates many components customers would normally have to populate externally, saving cost, board space, and simplifying the design. Additionally, the C8051F9xx family integrates a highly efficient DC/DC converter capable of operation down to 0.9V, thus enabling designers to lower their system cost and reduce board space by moving to a single cell battery implementation. The integrated DC/DC converter is capable of driving external components such as LEDs, sensors or transceivers up to 65mW, and has a programmable output voltage ranging from 1.8 to 3.3V.
