SX1504/SX1505/SX1506 4/8/16 Channel GPIO WIRELESS & SENSING
SX1504/SX1505/SX1506
4/8/16 Channel GPIO with NINT and NRESET
GENERAL DESCRIPTION
The SX1504, SX1505 and SX1506 are complete General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment. They allow easy serial 2 expansion of I/O through a standard I 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 2.
