Microchip Technology SMART E70, V70, & 71 32-Bit Microcontrollers

Microchip Technology SMART E70, V70, and V71 32-Bit Microcontrollers are members of a family of Flash MCUs based on the high-performance 32-Bit Arm® Cortex®-M7 Processor with a Double Precision Floating Point Unit (FPU). These devices operate at up to 300MHz and feature up to 2048Kbytes of Flash and up to 384Kbytes of multiport SRAM. The on-chip SRAM can be configured as Tightly Coupled Memory (TCM) or system memory. A multiport access to the SRAM guarantees a minimum access latency.
