Description  
■ 8 mA current drive/sink on each GPIO at 3.3 V  
■ < 1µA suspend current  
The STMPE1600 is a GPIO (general purpose  
input/output) port expander able to interface a  
main digital ASIC via the two-line bidirectional bus  
(I2C). A separate GPIO expander IC is often used  
in mobile multimedia platforms to solve the  
problems of the limited amount of GPIOs typically  
available on the digital engine.  
■ ESD protection exceeds 2 KV HBM per  
JESD22-A114  
■ Latch-up testing exceeding 100 mA  
■ Package: QFN24 (4 x 4 mm with 0.5 mm pitch)  
I/O expanders provide a simple solution when  
additional I/O are needed for several interface  
functions such as sensors, pushbuttons, LEDs,  
fans, etc.  
Applications  
■ Portable media players  
■ Game consoles  
■ Mobile phones  
The STMPE1600 offers great flexibility as each  
I/O can be configured as input or output. The  
device has been designed with very low quiescent  
current and includes a wakeup feature for each  
I/O, to optimize the power consumption of the  
device.  
■ Smart phones
