Cortex-M7 Contains Configurable Tightly Coupled Memory @Atmel

Download this article in .PDF format This file type includes high resolution graphics and schematics when applicable. Atmel’s SAM E70 now adds Cortex-M7 (see “Cortex-M7 Takes Aim at the IoT High Ground ”) support to its ARM product portfolio. The Cortex-M7, which features high-performance floating-point capability, is the high end of the ARM architecture microcontroller line, yet it also bumps into the low-end, Cortex-A5 application-processor range. The SAM E70 is built around a 300-MHz Cortex-M7 with dual 16-kB L1 caches and up to 2 MB of on-chip flash storage (Fig. 1) . A 150-MHz bus matrix links the processing core, two dozen direct-memory-access (DMA) channels, and memory controllers to on-chip storage. The processor caches work with the on-chip and off-chip storage, including the QSPI port, although deterministic code should be loaded into RAM for optimal operation. R...
