SX1507/SX1508/SX1509

World’s Lowest Voltage Level Shifting GPIO with LED Driver and Keypad Engine

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 I

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

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.
