TLE9260QXXUMA2

Application Field and Working Principle of TLE9260QXXUMA2

The TLE9260QXXUMA2 by Infineon Technologies AG is an interface product that enables transmission, reception, and arbitration (TRA) of up to 32 universal asynchronous receiver/transmitters (UARTs) coming from various microcontroller (MCU) systems or other host applications.

The module\'s main application is to bundle and serialize UART ports as well as offload MCU systems from the processing of many individual streams. The most prominent features of this module are the management of 32 UART streams, its high communication speeds, and a low-power mode.

TLE9260QXXUMA2 is illuminated with a variety of commercial applications: it can be used in terrestrial and mobile communication, IoT and industrial automation, automotive, high-end computers, defense, and aviation.

Operation

The module is composed of an interface controller, an integrated Static RAM (SRAM), an integrated processor, and an integrated UART/user I/O transceiver. The integrated processor is responsible for the general operation of the module, alongside applications of peripheral devices, selection of the port to receive and transmit, and data processing.

The UART/user I/O transceiver carries out data transmission between the controller of the module, pending system peripherals, and a single UART bus. It is able to receive and transmit a 32-bit signal at once, which is convenient and beneficial for communication between modules. By providing an RTS/CTS line for each UART port, it allows for the simplest setup and use.

The interface controller is responsible for controlling the UART/user I/O transceiver, SRAM memory, and the processor. In combination with the power supply, it monitors their status and places the modules in either a low-power or a full-power mode, in accordance to the system\'s needs.

The integrated SRAM memory is used to store data and automatic write-increment operations. It can also store various copies of initial table values or codes which are automatically reloaded into the transceiver upon a system reset.

Design

TLE9260QXXUMA2 is designed as a compact standard size module with a small form factor. Each module measures 30.5 mm by 15.9 mm and 0.5 mm in height. As a standard modules product, it has an individual module identification number for tracking. Moreover, Infineon Technologies AG ensures that this module will meet thermal and electrical specifications at 0.25 µm and 0.35 µm CMOS voltage.

The module is designed to meet all regulatory standards, specifically IEEE 1149.1 (JTAG) and RoHS 2.0. It supports a dual power input that allows the host to control both the transmission and reception by configuring its transmit data rate through the command byte. Lastly, the module is furnished with protection from electrostatic discharge (ESD) and is provided with a permanent memory.

Conclusion

The TLE9260QXXUMA2 is a specialized interface product offering for up to 32 universal asynchronous receiver/transmitters (UARTs) from various microcontroller (MCU) systems or other host applications. It is able to support high-speed data transmission, low-power mode and an integrated processor to allow for general module operation and peripheral device applications. The module is designed to optimize space saving, conform to electrical and thermal requirements, as well as meet regulatory standards.
