Maxim Integrated (MAX7315ATE+) I/O Expander, 400 kH

Product OverviewThe MAX7315ATE+ is an 8 port I/O expander with LED intensity control, interruptand hot insertion protection in 16 pin TQFN package. This I2C/SMBus compatibleserial interfaced peripheral device provides microprocessors with 8 I/O ports.Each I/O port can be individually configured as either an open-drain currentsinking output rated at 50mA at 5.5V or logic input with transition detection. Aninth port can be used for transition detection interrupt or as general purposeoutput. The outputs are capable of directly driving LEDs or providing logicoutputs with external resistive pull-up up to 5.5V. PWM current drive isintegrated with 8bits of control. Four bits are global control and apply to allLED outputs to provide coarse adjustment of current from fully OFF to fully ONin 14 intensity steps. Each output then has individual 4bit control whichfurther divides globally set current into 16 more steps. It is used in LEDstatus indication, RGB LED drivers, LCD & keypad backlights.Supply voltage range from 2V to 3.6VOperating temperature range from -40°C to 125°C400Kbps 2-wire serial interface, 5.5V tolerantPin and software compatible with PCA9534 and PCA9554(A) devicesControlled through 2-wire I2C/SMBus serial interface & can be configured to oneof 64 I2C addressesTransition detection with interrupt output, automatic two phase LED blinkingOverall 8bit PWM LED intensity control, global & individual 16 step intensitycontrolMaximum port output current is 50mA and serial clock frequency of 400KHzLow standby current of 1.2µA (typical) and 3.3µA (maximum)Inputs are overvoltage protected to 5.5VApplicationsConsumer Electronics, Portable DevicesProduct InformationChip Configuration: -Bus Frequency: 400kHzIC Interface Type: I2C, SMBusSupply Voltage Min: 2VSupply Voltage Max: 3.6VInterface Case Style: TQFNNo. of Pins: 16PinsNo. of I/O's: 8I/O'sProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
