MAX7360ETL+T

Sensor And Detector Interfaces Overview

The MAX7360ETL+T is an I2C-interfaced key-switch controller and LED driver manufactured by Analog Devices Inc./Maxim Integrated. It manages up to 64 keys via a static matrix scan, featuring a 16-byte FIFO for debounced events. The device includes eight +14V tolerant open-drain GPIOs capable of constant-current LED drive (up to 20mA) with 256-step PWM intensity control. It operates on a supply voltage of 1.62V to 3.6V with typical sleep current of 1µA. The component utilizes a 40-pin TQFN package (5mm x 5mm) with an exposed pad and supports a 400kbps I2C interface.

Sensor And Detector Interfaces Feature Summary

• Static key-matrix monitoring ensures low-EMI operation compared to dynamic scanning methods.
• Integrated autosleep and autowake modes minimize power consumption while maintaining FIFO data integrity.
• Eight open-drain ports support both logic I/O and constant-current LED driving with individual PWM brightness adjustment.

Sensor And Detector Interfaces Applications

• Cell phones
• PDAs
• Handheld games
• Portable consumer electronics

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix '+T' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 'E' designation aligns with the extended temperature range specifications (-40°C to +85°C) mandated by the system design requirements. Ensure compatibility with the host microcontroller's I2C voltage levels and address configuration settings before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this component when a microprocessor requires management of a large key matrix without dynamic scanning overhead. It is suitable for designs needing integrated LED drivers with precise PWM control alongside input expansion. Consider the 40-TQFN package dimensions for PCB layout constraints. Verify that the +14V tolerance on GPIO ports meets the external load requirements if interfacing with higher voltage peripherals.

Sensor And Detector Interfaces Part Context

The MAX7360ETL+T belongs to the Maxim Integrated MAX7360 family of I2C peripherals. It is functionally identical to the MAX7360EWX+, which utilizes a 36-bump wafer-level package (WLP). Both variants offer the same electrical characteristics and register map, differing primarily in physical footprint and thermal dissipation properties due to their respective packaging technologies.

Sensor And Detector Interfaces Replacement Considerations

The MAX7360EWX+ serves as a pin-compatible alternative within the same family, offering identical functionality in a 36-bump WLP package instead of the 40-TQFN form factor. No other direct substitutes are documented in the official datasheet.
