PRODUCT FEATURES

ENERAL DESCRIPTION

The SX1510B, SX1511B and SX1512B are complete

ultra low voltage 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 SPI 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.

•

1.2V to 5.5V (SX1510B) Low Operating

Voltage with Dual

(VCC1, VCC2)

Independent I/O Rails

ꢀ

Enable Direct Level Shifting Between I/O

Banks and Host Controller

•

5.5V Tolerant I/Os, Up to 15mA Output Sink on

All I/Os (No Total Sink Current Limit)

Integrated LED Driver for Enhanced Lighting

ꢀ

Intensity Control (256-step PWM)

Blink Control (224 On/Off values)

Breathing Control (224 Fade In/Out values)

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 1.2V

(SX1510B) while the dual I/O banks can operate

between 1.2V and 5.5V (SX1510B) independent of

the core voltage and each other (5.5V tolerant).

•

On-Chip Keypad Scanning Engine

ꢀ

Support Up to 8x8 Matrix (64 Keys)

Configurable Input Debouncer

4/8/16 Channels of True Bi-directional Style I/O

ꢀ

Programmable Pull-up/Pull-down

Push/Pull or Open-drain outputs

Programmable Polarity

The SX1510B, SX1511B and SX1512B 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.

•

Open Drain Active Low Interrupt Output (NINT)

ꢀ

Bit Maskable

Programmable Edge Sensitivity

Built-in Clock Management (Internal 2MHz

Oscillator/External Clock Input, 7 clock values)

In addition, keypad applications are also supported

with an on-chip scanning engine that enables

continuous keypad monitoring up to 64 keys without

any additional host interaction reducing the bus

activity.

ꢀ

OSCIO can be Configured as GPO

•

SPI Compatible Slave Interface (up to 20MHz)

Power-On Reset and Reset Input (NRESET)

Ultra Low Current Consumption: 1uA Typ

-40°C to +85°C Operating Temperature Range

Up to 2kV HBM ESD Protection

The SX1510B, SX1511B and SX1512B have the

ability to generate mask-programmable interrupts

based on a falling/rising edge of any of its GPIO lines.

A dedicated pin (NINT) indicates to a host controller

that a state change occurred on one or more of the

lines. Each GPIO is programmable via a bank of 8-bit

configuration registers that include data, direction,

pull-up/pull-down, interrupt mask and interrupt

registers. These I/O expanders feature small footprint

packages and are rated from -40°C to +85°C

temperature range.

Small Footprint Packages

Pb & Halogen Free, RoHS/WEEE compliant
