​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.

    Lowest Voltage Operation

    The C8051F92x/3x family not only provides high performance while saving power but also unprecedented functional density in a small footprint. With an integrated dc-dc converter, the C8051F92x/3x family is the industry's first MCU capable of operating down to 0.9 V, enabling single-cell battery operation and dramatically increasing battery life for dual-cell applications, utimately shrinking the form factor and cost of battery-powered products.

    Maximized Power Efficiency

    The C8051F92x/3x family is optimized in all operating modes to enable customers to either move to a single-cell design or increase the system's battery life by up to 2x in parallel dual-cell designs.

    Highest Functional Density

    With 64 kB of Flash and 4 kB of RAM in a 4 mm x 4 mm package, the C8051F92x/3x provides customers with increased memory for data-intensive applications. The small form factor makes these devices ideal for applications where end-product size is critical.

    Best-in-Class Tools

    The complete, low-cost professional C8051F930 Development Kit includes everything required to immediately begin system design. Silicon Labs' battery Life Estimator, a GUI-based tool that provides detials on typical battery discharge characteristics, as well as a user-editable spreadsheet inluded as part of the development kit. An inexpensive C8051F931 ToolStick Daughter Card and Base Adapter also provide a full development environment.
