X-STM32MP-IGTW1

概要

The X-STM32MP-IGTW1 is an MPU expansion board designed for industrial IoT gateway applications, featuring a range of wired communication interfaces.

The X-STM32MP-IGTW1 operates with a power supply between 12 to 24 V and interfaces with the STM32MP microprocessor via a 40-pin GPIO connector using I2C, UART, FDCAN, and GPIO connections. The board is compatible with the STM32MP257F-DK connector layout.

The ST4E1240 is a high-speed RS-485 transceiver supporting data rates up to 20 Mbps, operating from 3.0 to 5.5 V. It features low-power consumption (1.5 mA active, <1 µA shutdown), integrated ESD protection, and fail-safe mechanisms for reliable communication in industrial applications.

The ST3232C is a dual RS-232 transceiver operating from 3.0 to 5.5 V, supporting data rates up to 400 kbps. It features integrated charge pump capacitors and has low-power consumption (1 µA in shutdown).

A further serial communication capability is given by a high-speed CAN transceiver designed for reliable communication in automotive and industrial applications, providing robust data transmission with data rate up to 1 Mbps and reception with low-power consumption, ±36 VBUS fault tolerance, excellent noise immunity and includes autobaud loopback.

The M41T83 is a real-time clock (RTC) with a built-in battery backup, providing accurate timekeeping for embedded systems. It operates from 1.8 to 5.5 V, features a low-power consumption of 1 µA in battery mode, and includes programmable alarms, a watchdog timer, and a 32.768 kHz output for precise timing applications.

The STSAFE-A110 is a secure element on the board that provides hardware-based authentication and cryptographic services, ensuring data integrity and confidentiality for IoT devices and peripherals.

The M24C32-R is a 32-kbit EEPROM with I²C interface, providing nonvolatile memory for data storage, ideal for industrial applications requiring reliable data retention and easy integration.
