STMicroelectronics SPEAr1340 Datasheet
The SPEAr1340 is a system-on-chip belonging to the SPEA family of embedded microprocessors, designed for consumer and professional applications requiring advanced human-machine interfaces (HMI) combined with high performance. It supports both real-time operating systems (RTOS) and high-level operating systems such as Android, Linux, and Windows Embedded Compact 7.
The device architecture is based on several internal components communicating through a multilayer interconnection matrix (BUSMATRIX). Key features include dual ARM Cortex-A9 cores running up to 600 MHz, a shared 512 KB L2 cache, and high-performance master agents directly interconnected with the DDR memory controller. It integrates various connectivity options including USB 2.0, Gigabit Ethernet, PCIe 2.0, SATA, and multiple memory card interfaces.
