4/8/16 Channel Low Voltage GPIO

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 I 2 C 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 level to a component running at a different voltage level. The core is operating as low as 1.2V while the I/O banks CAN operate between 1.2V and 5.5V independent of the core voltage and each other. Each GPIO is programmable via 8-bit configuration Registers Data Registers direction Registers pull- up/pull-down Registers interrupt mask Registers and interrupt Registers allow the system master to program and configure 4 or 8 or 16-GPIOs using a standard 400kHz I 2 C Interface The SX1501 SX1502 and SX1503 offer a unique fully programmable Logic functions like a PLD to give more flexibility and reduce external Logic Gates used for standard applications. The SX1501 SX1502 and SX1503 have the ability to generate mask-programmable interrupts based on falling/rising edge of any of its GPIO lines. A By Semtech Corporation
