AM2634-Q1

The AM2634-Q1 is a high-performance microcontroller from Texas Instruments, designed for automotive and industrial applications requiring robust real-time processing. Built on the ARM Cortex-R5F core running at up to 400 MHz, it offers deterministic performance essential for safety-critical systems. The device includes a rich set of peripherals such as dual CAN FD controllers, Ethernet MAC, and multiple high-speed interfaces like SPI, I2C, and UART, enabling seamless communication in complex embedded environments. This microcontroller features integrated memory with 1 MB of on-chip SRAM and supports external flash storage via QSPI or eMMC interfaces, ensuring flexibility in system design. It also includes hardware acceleration for cryptographic functions, such as AES-256 and SHA-2, which enhances security for secure boot, over-the-air updates, and data protection in automotive systems. The AM2634-Q1 is AEC-Q100 Grade 1 qualified, making it suitable for harsh automotive environments where reliability and temperature resilience are critical. Its architecture supports real-time operating systems (RTOS) and deterministic interrupt handling, ideal for motor control, powertrain management, and advanced driver-assistance systems (ADAS). The inclusion of a dedicated floating-point unit (FPU) and support for fixed-point math accelerators further improve computational efficiency for signal processing tasks such as sensor fusion and control algorithms. Additionally, the device integrates a digital signal processor (DSP) engine for high-speed mathematical operations commonly used in motor control and audio processing. Power efficiency is optimized through dynamic voltage and frequency scaling (DVFS), allowing the device to adjust performance based on workload while minimizing energy consumption—a key consideration in battery-powered and electric vehicle applications. The AM2634-Q1 also provides comprehensive diagnostic and monitoring features, including ECC memory protection, watchdog timers, and built-in self-test (BIST) capabilities, which enhance system integrity and fault tolerance. Designed for scalability, the AM2634-Q1 supports various package options, including a 143-pin VQFN, facilitating integration into space-constrained designs. Its development ecosystem includes TI’s Code Composer Studio (CCS), C2000™ Real-Time Control Library, and support for AUTOSAR, enabling rapid prototyping and compliance with automotive software standards. These features make it an ideal solution for next-generation automotive electronics, industrial automation, and other demanding applications requiring both high performance and stringent safety requirements.
