ماژول توسعه دهنده  PCF8575  I/O با قابلیت توسعه I2C

Function : I2C interface via a common IO port expansion. I2C basic functions only need to occupy two IO ports use this module to extend the 16 IO. An I2C bus can do more with eight modules, namely, expandable up the 8X16 = 128 IO ports. If the module can be assigned to an interrupt port to achieve effective input reading the report.

Characteristics :
Low standby current, max 10uA
I2C to parallel port expander
Open-Drain Interrupt Output
Compatible with most microcontrollers large
The fastest to 400kHz I2C bus
Address by three hardware address pins set up simultaneously connect up to 8 devices
Output latch having a large current drive capability and can directly drive LED
Actively Driving to VCC high voltage output
Latch-up performance exceeds 100mA Per JESD 78, Type II
Human Body Model ESD Protection Exceeds JESD22-2000V (A114-A) 200V machine model (A115-A) 1000V Charged Device Model (C101)

Pinout:
VCC: DC 2.5V-5V
SCL:input:12C bus SCL. The board has pull-up resistance to VCC
SDA:Input/Output:12C bus SDA. The board has pull-up resistor to VCC
INT:input:Open-Drain interrupt output,The board has pull-up resistor to VCC. When use the Expansion Port as the input port, and apply the interrupt pin for use to realize the utmost read instantaneity of the system to expansion port.
A0,A1,A2:input:12C device address hardware set pin. The 3 pin ‘s condition equal to the last 3 bits on the device address. It can connect with the ground, or VCC.
P00-P17:Input/Output:Extension I/O port
