C8051F901-GU

C8051F90x/91x Ultra Low-Power MCUs

The C8051F901-GU is an ultra-low power microcontroller (MCU) that has been designed from the ground up to be highly power effective. The MCU features a powerful 8051 core with 25 MHz performance along with 8 kB Flash, 0.75 kB RAM  and a 10-bit, 15-ch., 300 ksps ADC in a 8.65x3.9 mm, QSOP24. The C8051F901-GU also operates from 0.9 - 3.6 V to enable single cell battery designs and is ideal for applications such as energy harvesting, alarm systems, smoke detectors, portable medical products and other low-power applications.
