【基本数据】

【产品特性】

• 4/8/16 channel of I/Os
True bi-directional style I/O
Programmable Pull-up/Pull-down
Push/Pull outputs
• 1.2V to 5.5V independent operating voltage for
all supply rails (VDDM, VCC1, VCC2)
• 5.5V compatible I/Os, up to 24mA output sink
(no total sink current limit)
• Fully programmable logic functions (PLD)
• 400kHz 2-wire I
2
C compatible slave interface
• Open drain active low interrupt output (NINT)
Bit maskable
Programmable edge sensitivity
• Power-On Reset and reset input (NRESET)
• Ultra low current consumption of typ. 1uA
• -40°C to +85°C operating temperature range
• Ultra-Thin 3x3mm QFN-UT-20 package
(SX1501/SX1502)
• Ultra-Thin 4x4mm QFN-UT-28 package
(SX1503)
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.

【产品应用】

• Cell phones, PDAs, MP3 players
• Digital camera
• Portable multimedia player
• Notebooks
• GPS Units
• Industrial, ATE
• Any battery powered equipment
