![]() The Cortex-M7 is the first ARM microcontroller to use branch prediction. ![]() Initial benchmarks have shown C++ code compiled by Arduino tends to achieve two instructions about 40% to 50% of the time while performing numerically intensive work using integers and pointers. The Cortex-M7 is a dual-issue superscaler processor, meaning the M7 can execute two instructions per clock cycle, at 600MHz! Of course, executing two simultaneously depends upon the compiler ordering instructions and registers. The ARM Cortex-M7 brings many powerful CPU features to a true real-time microcontroller platform. No soldering is required allowing you to get started as quickly as possible! The best part of this version of Teensy 4.1 is that it includes headers already attached. The Teensy 4.1 is the same size and shape as the Teensy 3.6 (2.4in by 0.7in), and provides greater I/O capability, including an ethernet PHY, SD card socket, and USB host port. The Teensy 4.1 is the newest iteration of the astoundingly popular development platform that features an ARM Cortex-M7 processor at 600MHz, with a NXP iMXRT1062 chip, four times larger flash memory than the 4.0, and two new locations to optionally add more memory. ![]() Teensy 4.1 also can also be overclocked, well beyond 600MHz! If a coin cell is connected to VBAT, Teensy 4.1's RTC also continues to keep track of date & time while the power is off. By connecting a pushbutton to the On/Off pin, the 3.3V power supply can be completely disabled by holding the button for five seconds, and turned back on by a brief button press. 1 also provides a power shut off feature.
