16-bit I²C and SMBus, low power I/O port with interrupt

PCA9535

I C/SMBus applications and was developed to enhance the Philips

family of I C I/O expanders. The improvements include higher drive

capability, 5 V I/O tolerance, lower supply current, individual I/O

configuration, and smaller packaging. I/O expanders provide a

simple solution when additional I/O is needed for ACPI power

switches, sensors, pushbuttons, LEDs, fans, etc.

The PCA9535 consist of two 8-bit Configuration (Input or Output

selection); Input, Output and Polarity inversion (Active HIGH or

Active LOW operation) registers. The system master can enable the

I/Os as either inputs or outputs by writing to the I/O configuration

bits. The data for each Input or Output is kept in the corresponding

Input or Output register. The polarity of the read register can be

inverted with the Polarity Inversion Register. All registers can be

read by the system master. Although pin-to-pin and I C address

compatible with the PCF8575, software changes are required due to

the enhancements and are discussed in Application Note AN469.

FEATURES

• Operating power supply voltage range of 2.3 V-5.5 V

• 5 V tolerant I/Os

• Polarity inversion register

• Active LOW interrupt output

• Low stand-by current

The PCA9535 is identical to the PCA9555 except for the removal of

the internal I/O pull-up resistor which greatly reduces power

consumption when the I/Os are held LOW.

• Noise filter on SCL/SDA inputs

• No glitch on power-up

• Internal power-on reset

The PCA9535 open-drain interrupt output is activated when any

input state differs from its corresponding input port register state and

is used to indicate to the system master that an input state has

changed. The power-on reset sets the registers to their default

values and initializes the device state machine.

• 16 I/O pins which default to 16 inputs

• 0 to 400 kHz clock frequency

Three hardware pins (A0, A1, A2) vary the fixed I C address and

allow up to eight devices to share the same I C/SMBus. The fixed

• ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V

I C address of the PCA9535 is the same as the PCA9554 allowing

MM per JESD22-A115, and 1000 V CDM per JESD22-C101

up to eight of these devices in any combination to share the same

I C/SMBus.

• Latch-up testing is done to JESDEC Standard JESD78 which

exceeds 100 mA

• Offered in three different packages: SO24, TSSOP24, and

HVQFN24

I/O port

When an I/O is configured as an input, FETs Q1 and Q2 are off,

creating a high impedance input. The input voltage may be raised

above V to a maximum of 5.5 V.

If the I/O is configured as an output, then either Q1 or Q2 is on,

depending on the state of the Output Port register. Care should be

exercised if an external voltage is applied to an I/O configured as an

output because of the low impedance path that exists between the

pin and either V or V

The command byte is the first byte to follow the address byte during

a write transmission. It is used as a pointer to determine which of the

following registers will be written or read.

Figure 5. PCA9535 address

BUS TRANSACTIONS

Registers 0 and 1 — Input Port Registers

Writing to the port registers

Data is transmitted to the PCA9535 by sending the device address

and setting the least significant bit to a logic 0 (see Figure 5 for

device address). The command byte is sent after the address and

determines which register will receive the data following the

command byte.

This register is an input-only port. It reflects the incoming logic levels

of the pins, regardless of whether the pin is defined as an input or an

output by Register 3. Writes to this register have no effect.

Registers 2 and 3 — Output Port Registers

The eight registers within the PCA9535 are configured to operate

as four register pairs. The four pairs are Input Ports, Output Ports,

Polarity Inversion Ports, and Configuration Ports. After sending data

to one register, the next data byte will be sent to the other register in

the pair (see Figures 6 and 7). For example, if the first byte is sent to

Output Port (register 3), then the next byte will be stored in Output

Port 0 (register 2). There is no limitation on the number of data bytes

sent in one write transmission. In this way, each 8-bit register may

be updated independently of the other registers.

This register is an output-only port. It reflects the outgoing logic

levels of the pins defined as outputs by Register 6 and 7. Bit values

in this register have no effect on pins defined as inputs. In turn,

reads from this register reflect the value that is in the flip-flop

controlling the output selection, NOT the actual pin value.

Reading the port registers

In order to read data from the PCA9535, the bus master must first

send the PCA9535 address with the least significant bit set to a

logic 0 (see Figure 5 for device address). The command byte is sent

after the address and determines which register will be accessed.

After a restart, the device address is sent again but this time, the

least significant bit is set to a logic 1. Data from the register defined

by the command byte will then be sent by the PCA9535 (see

Figures 8 , 9, and 10). Data is clocked into the register on the falling

edge of the acknowledge clock pulse. After the first byte is read,

additional bytes may be read but the data will now reflect the

information in the other register in the pair. For example, if you read

Input Port 1, then the next byte read would be Input Port 0. There is

no limitation on the number of data bytes received in one read

transmission but the final byte received, the bus master must not

acknowledge the data.

This register allows the user to invert the polarity of the Input Port

Port data polarity is inverted. If a bit in this register is cleared (written

with a ‘0’), the Input Port data polarity is retained.

C0.7 C0.6 C0.5 C0.4 C0.3 C0.2 C0.1 C0.0

Interrupt Output

default

bit

The open-drain interrupt output is activated when one of the port

pins change state and the pin is configured as an input. The

interrupt is deactivated when the input returns to its previous state or

the input port register is read (see Figure 9). A pin configured as an

output cannot cause an interrupt. Since each 8-bit port is read

independently, the interrupt caused by Port 0 will not be cleared by a

read of Port 1 or the other way around.

C1.7 C1.6 C1.5 C1.4 C1.3 C1.2 C1.1 C1.0

default

This register configures the directions of the I/O pins. If a bit in this

as an input with high impedance output driver. If a bit in this register

is cleared (written with ‘0’), the corresponding port pin is enabled as

an output. At reset the device’s ports are inputs.

Note that changing an I/O from an output to an input may cause a

false interrupt to occur if the state of the pin does not match the

contents of the Input Port register.

Figure 11. Typical application

Minimizing I when the I/O is used to control LEDs

When the I/Os are used to control LEDs, they are normally connected to V through a resistor as shown in Figure 11. Since the LED acts as a

diode, when the LED is off the I/O V is about 1.2 V less than V . The supply current, I , increases as V becomes lower than V and is

specified as ∆I in the DC characteristics table.

Designs needing to minimize current consumption, such as battery power applications, should consider maintaining the I/O pins greater than or

equal to V when the LED is off. Figure 12 shows a high value resistor in parallel with the LED. Figure 13 shows V less than the LED supply

voltage by at least 1.2 V. Both of these methods maintain the I/O V at or above V and prevents additional supply current consumption when

the LED is off.
