2. C8051F990 Slider Evaluation Kit Overview

The C8051F990 Slider Evaluation Kit demonstrates the system level possibilities that can be achieved when

combining Silicon Laboratories QuickSense™ technology with the C8051F99x ultra low power capacitive sensing

MCU. The result is a battery powered capacitive sensing solution that has the following features:

F990Slider-EK Quickstart Guide

Low Power Wake-on-Slide—Allows the system to be designed without any mechanical components. The

system wakes up when the user slides a finger across the slider. The system has a shelf life of over 5 years in

this low power wake-on-slide mode.

QuickSense™ Slider Control—Allows multiple capacitive sensing pads to be bound together to form a slider

control. The QuickSense API performs all required calculations and notifies the application software of the

finger position on the slider. The slider demo demonstrates this capability and has a runtime of over 120 hours

at the maximum LED setting. Runtime is limited by LED current and can be increased by dimming the LED.

Gesture Recognition—Quicksense™ events enable the ability to detect gestures, such as a “pinch”, on the

slider. In this system, the “pinch” gesture is used to switch between different demonstration modes.

Miniature Size—The C8051F990 MCU has a built in SmaRTClock oscillator (no crystal required) and is

available in a 3x3 mm package. The sleep mode current is 300 nA and the active mode current is 150 µA/MHz.

Battery Meter—Using the C8051F990’s 12-bit ADC, the system is able to measure the battery voltage and

determine the remaining battery capacity.

LED Dimmer—The system dynamically reduces LED power consumption by driving the LEDs with a PWM

signal. Taking advantage of the fast 2 µs wake-up time, the MCU can efficiently wake up from sleep, adjust the

state of the LED, and go back to sleep very efficiently. This allows a flicker-free, low power, LED dimming mode.
