General description
The PCA9698 provides 40-bit parallel input/output (I/O) port expansion for I2C-bus
applications organized in 5 banks of 8 I/Os. At 5 V supply voltage, the outputs are capable
of sourcing 10 mA and sinking 25 mA with a total package load of 1 A to allow direct
driving of 40 LEDs. Any of the 40 I/O ports can be configured as an input or output.
The PCA9698 is the first GPIO device in a new Fast-mode Plus (Fm+) family. Fm+
devices offer higher frequency (up to 1 MHz) and longer, more densely populated bus
operation (up to 4000 pF).
The device is fully configurable: output ports can be programmed to be totem-pole or
open-drain and logic states can change at either the Acknowledge (bank change) or the
Stop Command (global change), each input port can be masked to prevent it from
generating interrupts when its state changes, I/O data logic state can be inverted when
read by the system master.
An open-drain interrupt output pin (INT) allows monitoring of the input pins and is asserted
each time a change occurs in one or several input ports (unless masked).
The Output Enable pin (OE) 3-states any I/O selected as output and can be used as an
input signal to blink or dim LEDs (PWM with frequency > 80 Hz and change duty cycle).
A ‘GPIO All Call’ command allows to program multiple Advanced GPIOs at the same time
even if they have different I2C-bus addresses. This allows optimal code programming
when more than one device needs to be programmed with the same instruction or if all
outputs need to be turned on or off at the same time (for example, LED test).
The Device ID, hard coded in the PCA9698, allows the system master to read
manufacturer, part type and revision information.
The SMBus Alert feature allows the SMBALERT pins of multiple devices with this feature
to be connected together to form a wired-AND signal and to be used in conjunction with
the SMBus Alert Response Address.
The internal Power-On Reset (POR) or hardware reset pin (RESET) initializes the 40 I/Os
as inputs. Three address select pins configure one of 64 slave addresses.
The PCA9698 is available in 56-pin TSSOP and HVQFN packages and is specified over
the
40 °C to +85 °C industrial temperature range.
