World’s Lowest Voltage Level Shifting GPIO

SX1507/SX1508/SX1509
World’s Lowest Voltage Level Shifting GPIO with LED Driver and Keypad Engine
GENERAL DESCRIPTION
The SX1507, SX1508 and SX1509 are complete ultra
low voltage 1.2V to 3.6V General Purpose parallel
Input/Output (GPIO) expanders ideal for low power
handheld battery powered equipment. This family of
GPIOs comes in 4-, 8-, 16-channel configuration and
allows easy serial expansion of I/O through a
standard 400kHz I2C 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,
thus eliminating the need for extra level translating
circuits. The core is operating as low as 1.425V while
the dual I/O banks can operate between 1.2V and
3.6V independent of the core voltage and each other
(5.5V tolerant).
The SX1507, SX1508 and SX1509 feature a fully
programmable LED Driver with internal oscillator for
enhanced lighting control such as intensity (via 256-
step PWM), blinking and breathing (fade in/out) make
them highly versatile for a wide range of LED
applications.
In addition, keypad application is also supported with
the on-chip scanning engine which enables
continuous keypad monitoring up to 64 keys without
any additional host interaction and further reduce the
bus activity.
The SX1507, SX1508 and SX1509 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 lines.
Each GPIO is programmable via 8-bit configuration
registers such as data registers, direction registers,
pull-up/pull-down registers, interrupt mask registers
and interrupt registers. These I/O expanders come in
small footprint packages and are rated from -40°C t o
+85°C temperature range.
