CAP1298-1-A4-TR

Overview

The CAP1298-1-A4-TR is an eight-channel capacitive touch sensor controller manufactured by Microchip Technology. It features programmable sensitivity, automatic recalibration for parasitic capacitance, and proximity detection with signal guard capabilities. The device supports SMBus and I2C communication interfaces and operates within a supply voltage range of 3.0V to 5.5V. It offers multiple power states including Active, Standby, Combo, and Deep Sleep, with typical quiescent current as low as 5µA in Deep Sleep. The component is available in a 16-pin QFN 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 pattern touch recognition allowing simultaneous button detection
Low power operation with Deep Sleep mode drawing 5µA typical current

Applications

Desktop and notebook PCs
LCD monitors
Consumer electronics
Appliances

Procurement Notes

Verify the ordering suffix -A4-TR corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm that the device revision matches the intended application requirements. Ensure compatibility with the host controller's SMBus or I2C interface specifications before finalizing procurement orders.

Selection Notes

Select this component when an eight-channel solution with integrated proximity sensing is required. Consider the 16-pin QFN package for space-constrained designs. Evaluate power consumption requirements against the available Active, Standby, Combo, and Deep Sleep modes to optimize system battery life.

Part Context

The CAP1298 belongs to the CAP12XX series of capacitive touch controllers from Microchip Technology. This series expands upon previous RightTouch product lines by offering various slider, button, and proximity functions. The CAP1298 specifically provides eight channels, distinguishing it from lower channel count variants like the CAP1208 or CAP1203.

Replacement Considerations

Compatible substitutes include other members of the CAP12XX family such as the CAP1208, CAP1206, CAP1203, CAP1296, and CAP1293. These parts share similar interface protocols but differ in channel count and feature sets. Verify pinout compatibility and software register mapping when substituting.
