ENERAL DESCRIPTION  
The SX1510B, SX1511B and SX1512B are complete  
ultra low voltage General Purpose parallel  
Input/Output (GPIO) expanders ideal for low power  
handheld battery powered equipment. This family of  
GPIOs comes in 4-, 8-, 16-channel configuration and  
allows easy serial expansion of I/O through a  
standard SPI 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.

Intensity Control (256-step PWM)  
Blink Control (224 On/Off values)  
Breathing Control (224 Fade In/Out values)  
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,  
thus eliminating the need for extra level translating  
circuits. The core is operating as low as 1.2V  
(SX1510B) while the dual I/O banks can operate  
between 1.2V and 5.5V (SX1510B) independent of  
the core voltage and each other (5.5V tolerant).

The SX1510B, SX1511B and SX1512B feature a fully  
programmable LED Driver with internal oscillator for  
enhanced lighting control such as intensity (via 256-  
step PWM), blinking and breathing (fade in/out) make  
them highly versatile for a wide range of LED  
applications.

any additional host interaction reducing the bus

Up to 2kV HBM ESD Protection  
The SX1510B, SX1511B and SX1512B have the  
ability to generate mask-programmable interrupts  
based on a falling/rising edge of any of its GPIO lines.  
A dedicated pin (NINT) indicates to a host controller  
that a state change occurred on one or more of the  
lines. Each GPIO is programmable via a bank of 8-bit  
configuration registers that include data, direction,  
pull-up/pull-down, interrupt mask and interrupt  
registers. These I/O expanders feature small footprint  
packages and are rated from -40°C to +85°C  
temperature range.
