DESCRIPTION/ORDERING INFORMATION (CONTINUED)
PCF8575 provides general-purpose remote expansion most microcontroller families interface serial clock (SCL) serial data (SDA). device features 16-bit quasi-bidirectional input/output (I/O) port (P07-P00, P17-P10), including latched outputs with high-current drive capability directly driving LEDs. Each quasi-bidirectional used input output without data-direction control signal. power I/Os high. this mode, only current source (IOH) active. additional strong pullup (IOHT) allows fast-rising edges into heavily loaded outputs. This device turns when output written high switched negative edge SCL. I/Os should high before being used inputs. After power I/Os high, them used inputs. change setting I/Os either input outputs done with write mode. high applied externally that been written earlier low, large current (IOL) will flow GND. PCF8575 provides open-drain interrupt (INT) output, which connected interrupt input microcontroller. interrupt generated rising falling edge port inputs input mode. After time, tiv, signal valid. Resetting reactivating interrupt circuit achieved when data port changed original setting, data read from written port that generated interrupt. Resetting occurs read mode acknowledge (ACK) after rising edge signal write mode after falling edge signal. Interrupts that occur during clock pulse lost very short), resetting interrupt during this pulse. Each change I/Os after resetting detected transmitted INT. Reading from writing another device does affect interrupt circuit. sending interrupt signal this line, remote inform microcontroller there incoming data ports, without having communicate bus. Thus, PCF8575 remain simple slave device. Every data transmission from PCF8575 must consist even number bytes. first data byte every pair refers port (P07-P00), second data byte every pair refers port (P17-P10). write ports (output mode), master first addresses slave device, setting last byte containing slave address logic PCF8575 acknowledges, master sends first data byte P07-P00. After first data byte acknowledged PCF8575, second data byte (P17-P10) sent master. Once again, PCF8575 acknowledges receipt data, after which this 16-bit data presented port lines. number data bytes that sent successively limited. After every bytes, previous data overwritten. When PCF8575 receives pairs data bytes, first byte referred P07-P00 second byte P17-P10. third byte referred P07-P00, fourth byte P17-P10, Before reading from PCF8575, ports desired input should logic read from ports (input mode), master first addresses slave device, setting last byte containing slave address logic data bytes that follow values ports. data input port changes faster than master read, this data lost. When power applied VCC, internal power-on reset holds PCF8575 reset state until reached VPOR. that time, reset condition released, device I2C-bus state machine initializes default state. hardware pins (A0, used program vary fixed address allow eight devices share same SMBus. fixed address PCF8575 same PCF8575C, PCF8574, PCA9535, PCA9555, allowing eight these devices, combination, share same SMBus.

Interface
bidirectional consists serial clock (SCL) serial data (SDA) lines. Both lines must connected positive supply pullup resistor when connected output stages device. Data transfer initiated only when busy. communication with this device initiated master sending Start condition, high-to-low transition input/output while input high (see Figure After Start condition, device address byte sent, most significant (MSB) first, including data direction (R/W). This device does respond general call address. After receiving valid address byte, this device responds with ACK, input/output during high ACK-related clock pulse. address inputs (A2-A0) slave device must changed between Start Stop conditions. data byte follows address ACK. high, data from this device values read from port. low, data from master, output port. data byte followed sent from this device. other data bytes sent from master, following ACK, they ignored this device. Data output only complete bytes received acknowledged. output data valid time (tpv) after low-to-high transition SCL, during clock cycle ACK. bus, only data transferred during each clock pulse. data line must remain stable during high pulse clock period, changes data line this time interpreted control commands (Start Stop) (see Figure Stop condition, low-to-high transition input/output while input high, sent master (see Figure number data bytes transferred between Start Stop conditions from transmitter receiver limited. Each byte eight bits followed bit. transmitter must release line before receiver send bit. slave receiver that addressed must generate after reception each byte. Also, master must generate after reception each byte that been clocked slave transmitter. device that acknowledges pull down line during clock pulse that line stable during high pulse ACK-related clock period (see Figure Setup hold times must taken into account. master receiver must signal data transmitter generating acknowledge (NACK) after last byte that been clocked slave. This done master receiver holding line high. this event, transmitter must release data line enable master generate Stop condition.
