The STMUX1000L is an 8- to 16-bit bi-directional Multiplexer/Demultiplexer designed for applications that require signal routing at 10/100/1000 Megabit Ethernet speeds. It integrates three Single Pole Dual Throw (SPDT) Channels for LED support and is available in two different packages, the TSSOP56 and QFN56. This application note highlights various applications into which the STMUX1000L Gigabit LAN Switch can be designed, such as PC Notebooks and docking stations. These are applications where several electrical characteristics impact high performance data transfer, including low noise between signals, low RON, and low Con and Coff capacitance. Additionally, the superior performance of the STMUX1000L is illustrated when compared to a competitor's device.

STMPE2401 is a GPIO port expander that provides additional I/Os to the host processor to implement features such as increased number of inputs/outputs, expanding the number of control signals and mixed signal lines, controlling a greater number of peripherals.

AN2423 Application note describes the features of STMPE2401, including expansion logic, integrated intelligence and application scenarios.

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.

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.

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.
