SX1504/SX1505/SX1506
4/8/16 Channel GPIO
SX1504/SX1505/SX1506
4/8/16 Channel GPIO with NINT and NRESET
GENERAL DESCRIPTION
The SX1504, SX1505 and SX1506 are complete
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 I
2C 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.
These devices can also act as a level shifter to
connect a microcontroller running at one voltage level
to a component running at a different voltage level.
The core is operating as low as 2.5V while the I/O
banks
can
operate
between
2.5V
and
5.5V
independent of the core voltage and each other.
Each GPIO is programmable via 8-bit configuration
registers. Data registers, direction registers, pull-
up/pull-down registers, interrupt mask registers and
interrupt
registers
allow
the
system
master
to
program and configure 4 or 8 or 16-GPIOs using a
standard 400kHz I
2C interface.
The SX1504, SX1505 and SX1506 offer a unique
fully programmable logic functions like a PLD to give
more flexibility and reduce external logic gates used
for standard applications.
The SX1504, SX1505 and SX1506 have the ability to
generate mask-programmable interrupts based on
falling/rising edge of any of its GPIO lines. A
dedicated pin indicates to a host controller that a
state change occurred in one or more of the GPIO
lines.
The SX1504, SX1505 and SX1506 each come in a
small QFN-UT-20/28 package. All devices are rated
from -40°C to +85°C temperature range.
