PRODUCT FEATURES

ENERAL 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.

Open drain active low interrupt output (NINT)  
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 I2C interface.

Ultra-Thin 4x4mm QFN-UT-28 and TSSOP-28  
packages (SX1503)  
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  
dedicated pin indicates to a host controller that a  
state change occurred in one or more of the GPIO  
lines.  
Any battery powered equipment  
The SX1501, SX1502 and SX1503 each come in a  
small QFN-UT-20/28 package as well as a TSSOP-  
20/28 package. All devices are rated from -40°C to  
+85°C temperature range.
