Description

General part information

SX1508 Series

SX1508B is a world’s lowest voltage level shifting GPIO with LED driver and keypad engine. This complete ultra-low voltage General Purpose parallel Input/Output (GPIO) expander is ideal for low power handheld battery powered equipment. This family of GPIOs comes in 8-, 16channel configuration and allows easy serial expansion of I/O through a standard 400KHz 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. This 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, thus eliminating the need for extra level translating circuits. Typical application includes cell phones, PDAs, MP3 players, digital camera, notebooks, GPS units, any battery powered equipment.
