SX1502 - 8 Channel Low Voltage GPIO

Download the SX1502 datasheet PDF. This datasheet also covers the SX1501 variant, as both devices belong to the same 8 channel low voltage gpio family and are provided as variant models within a single manufacturer datasheet.

General Description

The SX1501, SX1502 and SX1503 are complete ultra low voltage General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment.

They allow easy serial expansion of I/O through a standard I2C interface.

Key Features

  • 4/8/16 channel of I/Os True bi-directional style I/O Programmable Pull-up/Pull-down Push/Pull outputs.
  • 1.2V to 5.5V independent operating voltage for all supply rails (VDDM, VCC1, VCC2).
  • 5.5V compatible I/Os, up to 24mA output sink (no total sink current limit).
  • Fully programmable logic functions (PLD).
  • 400kHz 2-wire I2C compatible slave interface.
  • Open drain active low interrupt output (NINT) Bit maskable Programmable edge sensitivity.

Channel Low Voltage GPIO with NINT and NRESET GENERAL DESCRIPTION The SX1501, SX1502 and SX1503 are complete ultra low voltage General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment. They allow easy serial expansion of I/O through a standard I2C interface. GPIO devices can provide additional control and monitoring when the microcontroller or chipset has insufficient I/O ports, or in systems where serial communication and control from a remote location is advantageous. These devices can also act as a level shifter to connect a microcontroller running at one voltage leve
