The C8051F9xx ultra-low-power microcontroller family is capable of operating down to 0.9 V and up to 3.6 V, enabling single-cell battery operation and increasing battery life for dual-cell applications. Offering an integrated dc-dc converter and on-chip low-dropout (LDO) regulator, F9xx microcontrollers have been designed to provide fast wake-up time, low active-mode, and ultra-low sleep mode current consumptions. The C8051F9xx family provides high performance while saving power in a small footprint. The F9xx family offers a range of flash memory sizes (from 2 to 64-kbytes) while also integrating a 10-bit, 300-ksps analog-to-digital converter (ADC) with an internal fast wake-up voltage reference, a smaRTClock timing module, and multiple internal oscillator options. Small-footprint package options include 4x4 mm QFN and 3x3 mm QFN.
The F9xx family delivers a deep-sleep-mode current of 10 nA without RTC running and with full RAM retention. The microcontroller can wake-up from its low power sleep mode with the CPU operating at 25 MIPS and ready to make an analog-to-digital converter (ADC) measurement within two microseconds. To save battery life in active mode, the F9xx's low-power architecture yields an active-mode current as low as150 µA/MHz. The latest addition to the F99x family is the C8051F99x capacitive touch-sense MCU, which includes Silicon Labs' high-performance capacitance-to-digital converter (CDC) for touch sensing applications.
