C8051F98x Ultra Low-Power Microcontrollers

The C8051F98x is the industry’s lowest power microcontroller (MCU), consuming as little as 150 µA/MHz in active mode and 10 nA in sleep mode with full memory retention. The C8051F98x expands the award-winning C8051F92x/3x low power MCU product portfolio by offering lower memory devices with further power reduction. The C8051F98x low power MCU family is software and hardware compatible with the C8051F92x/3x, C8051F90x/1x and C8051F99x families.

The F9xx series has the industry’s lowest active mode current consumption, which saves power when the application is running. It also has the industry’s lowest current consumption in sleep modes, which is often the most common mode in many battery-powered applications. Also, since the MCU cannot do any useful processing until all of the digital and analog circuitry all fully settled and operational, the F9xx series offers the industry’s fastest wake-up and analog settling time.

Sleep current as low as
10nA
Active current as low as
150uA/MHz
