Product details

Overview

F990SLIDEREK from Silicon Laboratories is a ready-to-use evaluation kit built around the C8051F990 ultra-low-power capacitive sensing MCU, demonstrating wake-on-slide gesture control, battery metering, and LED dimming on a single 3×3 mm board powered by a CR2032 coin cell. It supports three interactive modes-slider position tracking, battery voltage monitoring, and PWM-based brightness control-with sub-300 nA sleep current and 2 µs wake-up time.

For engineers reviewing the F990SLIDEREK datasheet, F990SLIDEREK pinout, F990SLIDEREK application, or F990SLIDEREK equivalent, this page provides verified technical context, key specifications, supply readiness, manufacturer background, and targeted FAQs for rapid prototyping of touch-enabled, battery-operated human interface devices.

Technical Context

The F990SLIDEREK implements Silicon Labs' QuickSense™ capacitive sensing framework on the C8051F990 MCU, enabling finger position interpolation across a multi-pad slider without external components. It uses the MCU's integrated SmaRTClock oscillator (no crystal required) and 12-bit ADC for battery voltage measurement.

Gesture recognition-including "pinch" detection for mode switching-is handled entirely in firmware via the QuickSense API. The board operates in three user-selectable modes with dynamic LED control driven by hardware PWM and fast wake-from-sleep transitions.

Key Specifications

FAQ

What is the primary function of the F990SLIDEREK?

The F990SLIDEREK is an evaluation kit that demonstrates capacitive slider control, gesture recognition, and battery-aware LED dimming using the C8051F990 MCU. It requires no external power supply or programming tools-just remove the battery tab and interact with the slider. The F990SLIDEREK enables immediate validation of QuickSense™ touch algorithms and low-power system behavior in real-world conditions.

Does the F990SLIDEREK require a debugger or programming interface to operate?

No-the F990SLIDEREK ships pre-programmed with demonstration firmware and runs immediately upon battery activation. No JTAG adapter, IDE, or host PC is needed for basic operation. Firmware updates or custom development require the C8051F990's standard debug interface, but the F990SLIDEREK itself functions as a standalone interactive demo unit out of the box.

How long does the CR2032 battery last on the F990SLIDEREK?

The CR2032 battery delivers over 120 hours of active runtime at maximum LED brightness, and more than five years of shelf life in wake-on-slide standby mode. Runtime scales inversely with LED current draw; dimming reduces power consumption significantly. Battery voltage is continuously monitored via the C8051F990's 12-bit ADC and reported in Mode 1 (Battery Meter) on the F990SLIDEREK.

What gestures are supported by the F990SLIDEREK, and how are they detected?

The F990SLIDEREK supports slide motion and pinch gestures. Slide detection tracks finger position across the capacitive pads to drive LED movement; pinch-simultaneous touch on A and B buttons followed by inward motion-cycles through the three operating modes. All gesture processing is performed in real time by the QuickSense™ firmware library running on the C8051F990 MCU inside the F990SLIDEREK.

Can the F990SLIDEREK be used for production design, or is it evaluation-only?

The F990SLIDEREK is strictly an evaluation and demonstration tool-not a production-ready module. However, its underlying C8051F990 MCU and QuickSense™ firmware are qualified for volume deployment. Engineers use the F990SLIDEREK to validate touch performance, power profiles, and algorithm behavior before designing custom PCBs based on the same MCU and sensor layout principles.
