CAP1298-1-SL-TR

Overview

The CAP1298-1-SL-TR is an eight-channel capacitive touch sensor controller manufactured by Microchip Technology. It operates on a 3V to 5.5V supply and features programmable sensitivity with automatic recalibration for parasitic capacitance. The device supports proximity detection via a signal guard, multiple pattern touch recognition, and low-power states including Deep Sleep at 5µA typical current. It communicates through SMBus or I2C interfaces and is housed in a 14-pin SOIC package.

Feature Summary

Eight individual capacitive touch sensor inputs with programmable sensitivity and automatic recalibration
Proximity detection capability with optional signal guard to reduce noise sensitivity
Multiple power states including Active, Standby, Combo, and Deep Sleep modes
SMBus and I2C compliant communication interface

Applications

Desktop and notebook PCs
LCD monitors
Consumer electronics
Appliances

Procurement Notes

Verify the -TR suffix indicates tape and reel packaging when ordering. Confirm the specific revision of the datasheet DS00001571B matches the silicon revision required for your design. Ensure compatibility with your host controller's SMBus or I2C voltage levels before procurement.

Selection Notes

Select this component for designs requiring up to eight touch buttons with proximity sensing capabilities. Consider the 14-pin SOIC package for surface mount assembly. Evaluate the power consumption requirements against the available Active, Standby, and Deep Sleep modes to optimize battery life in portable applications.

Part Context

The CAP1298 belongs to the CAP12XX series of capacitive touch controllers from Microchip Technology. This series expands upon previous RightTouch products by offering integrated slider, button, and proximity functions. The CAP1298 specifically provides eight channels, distinguishing it from lower channel count variants like the CAP1206 or CAP1208.

FAQ

What is the quiescent current in Deep Sleep mode?

The CAP1298 draws 5µA typical current in Deep Sleep mode.

Does the CAP1298 support I2C communication?

Yes, the device supports both SMBus and I2C protocols, including Fast Mode up to 400kHz.

How does the Signal Guard function?

The Signal Guard isolates the proximity antenna from nearby conductive surfaces that would otherwise attenuate the electric field and reduces system noise sensitivity.
