PRODUCT FEATURES

ENERAL DESCRIPTION

The SX1501, SX1502 and SX1503 are complete ultra

low voltage 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 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.

•

4/8/16 channel of I/Os

ꢀ

True bi-directional style I/O

Programmable Pull-up/Pull-down

Push/Pull outputs

•

1.2V to 5.5V independent operating voltage for

all supply rails (VDDM, VCC1, VCC2)

5.5V compatible I/Os, up to 24mA output sink

(no total sink current limit)

•

Fully programmable logic functions (PLD)

400kHz 2-wire I²C compatible slave interface

Open drain active low interrupt output (NINT)

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 1.2V while the I/O

banks can operate between 1.2V and 5.5V

independent of the core voltage and each other.

ꢀ

Bit maskable

Programmable edge sensitivity

•

Power-On Reset and reset input (NRESET)

Ultra low current consumption of typ. 1uA

-40°C to +85°C operating temperature range

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 I²C interface.

Ultra-Thin 3x3mm QFN-UT-20 and TSSOP-20

packages (SX1501/SX1502)

•

Ultra-Thin 4x4mm QFN-UT-28 and TSSOP-28

packages (SX1503)

The SX1501, SX1502 and SX1503 offer a unique

fully programmable logic functions like a PLD to give

more flexibility and reduce external logic gates used

for standard applications.

YPICAL APPLICATIONS

•

Cell phones, PDAs, MP3 players

Digital camera

Portable multimedia player

Notebooks

GPS Units

Industrial, ATE

The SX1501, SX1502 and SX1503 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.

Any battery powered equipment

The SX1501, SX1502 and SX1503 each come in a

small QFN-UT-20/28 package as well as a TSSOP-

20/28 package. All devices are rated from -40°C to

+85°C temperature range.
