com Wired Remote Controllers General Description The MAX11041/MAX11042 wired remote controllers convert up to six or 30 different pushbuttons into an I2C register.
Together with low-cost pushbutton switches and 1% resistors, the MAX11041/MAX11042 are total solutions over a single-wire interface.
A wired remote controller easily piggybacks to a standard 3.
5mm headphone jack using a fourth contact or one of the audio signals.
To conserve battery life, the MAX11041/MAX11042 consume only 5µA (typ) while reading keypresses in real time without microprocessor (µP) polling.
The devices send the debounced keypress along with key duration to the application processor over the I2C interface.
An 8-word FIFO buffer records up to four keypress events to allow plenty of time for the application processor to respond to the MAX11041/MAX11042.
The MAX11041/MAX11042 include ±15kV ESD protection devices on the FORCE and SENSE inputs to ensure IEC 61000-4-2 compliance without any external ESD devices.
The MAX11041/MAX11042 are available in 12-bump UCSP™ and 12-pin TQFN packages.
The devices are specified over the extended temperature range (-40°C to +85°C).
