SX1504/SX1505/SX1506

4/8/16 Channel GPIO with NINT and NRESET

The SX1504, SX1505 and SX1506 are complete

General

expanders ideal for low power handheld battery

powered

expansion of I/O through a standard I

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

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

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 as well as a TSSOP-

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

+85° C temperature range.
