Low-Voltage Low-Power MCUs

The C8051F92x/3x is the industry's first MCU family capable of full spec operation down to 0.9 V and up to 3.6 V, enabling single-cell battery operation as well as dramatically increasing battery life for dual-cell applications. With an integrated dc-dc converter, the C8051F92x/3x has been designed to provide a fast wake-up time, low active mode and ultra-low sleep mode current consumptions.

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.
