ST AN2424 handbook
STMPE2401 is the first of ST's port-expander logic products, and in addition to providing additional I/Os, it also has advanced features such as PWM control, Keypad scanning, and Rotator dial control, which can reduce the processor load. This application note explains how to configure STMPE24001's PWM controller to achieve LED backlighting, brightness control, and LED blinking.
ST AN2466 handbook
STMPE801 is an eight-bit port expander that can be interfaced to the main digital ASIC or processor via the two-line bidirectional I2C bus. This application note explains the setup and hardware interfacing of the device to the main processor.
ST AN2471 handbook
This application note presents the STMAV335 evaluation board and PCB layout recommendation. STMAV335 is used for switching analog video signals on the back panel of television sets or monitors.
ST AN2472 handbook
This application note introduces the STMAV340 4-channel SPDT high bandwidth, low Ron switch which provides a simple, inexpensive means to switch high quality video signals without corrupting them. It is a versatile video switch which can be used in multiple applications such as televisions, notebooks, graphic cards and DVD players.

ST AN3090 handbook
This application note describes the features and characteristics of the STP16xPPx05 family of LED drivers, with particular focus on two important features: output error detection and auto power-saving.
ST AN3245 handbook
This document is a hardware and software guide for the STMPE1801 Xpander Logic™ 18-bit enhanced port expander with keypad controller. The product is a GPIO (general purpose input/output) port expander that can interface with a main digital ASIC via a two-line bidirectional bus (I2C). It offers the flexibility to be configured into a 10x8 matrix keypad controller for QWERTY keyboards and general purpose inputs/outputs. This document provides guidelines and information complementary to the STMPE1801 datasheet, which is necessary for the successful design of STMPE1801 in applications. The first part of the document highlights information on the hardware including external components/connectivity, power, etc. The second part of the document focuses on information regarding the software, in which programming sample codes are shown.
