CAP1208-1-SL-TR

Overview

The CAP1208-1-SL-TR is an eight-channel capacitive touch sensor controller manufactured by Microchip Technology. It features a 14-pin SOIC package and operates on a supply voltage of 3V to 5.5V with a typical active current consumption of 750µA. The device supports SMBus and I2C communication interfaces, allowing for host controller integration. It includes programmable sensitivity, automatic recalibration for parasitic capacitance, and multiple pattern touch recognition. The component functions within a temperature range of -40°C to 125°C and offers low-power states including Deep Sleep with 5µA quiescent current.

Feature Summary

• Eight individual capacitive touch sensor inputs with programmable sensitivity and automatic recalibration capabilities.
• Multiple Pattern Touch recognition that detects specific simultaneous button combinations and generates interrupts.
• Supports Active, Standby, and Deep Sleep power states to optimize energy consumption based on application requirements.
• Integrated analog filtering, RF detection avoidance filters, and digital EMI blockers for system noise reduction.

Applications

• Desktop and Notebook PCs
• LCD Monitors
• Consumer Electronics
• Appliances

Procurement Notes

Verify the ordering suffix SL indicates the 14-pin SOIC package configuration. Confirm the -1 suffix corresponds to the specific SMBus address 0101_000(r/w). Ensure the TR suffix matches the required reel packaging format for automated assembly processes.

Selection Notes

Select this component when eight independent touch channels are required with SMBus or I2C connectivity. Consider the 14-pin SOIC package for surface mount applications requiring wider pin spacing. Evaluate power state configurations if standby current optimization is critical for the target system design.

Part Context

This part belongs to the CAP1208 family of capacitive touch sensors. It shares functional similarities with variants like the CAP1206 but provides additional input channels. The -SL-TR designation specifically identifies the SOIC package and tape-and-reel shipping method.

Replacement Considerations
