Teensy 4.1 is the latest iteration of the surprisingly popular development platform that features a 600 MHz ARM Cortex-M7 processor, with an NXP iMXRT1062 chip, four times the 4.0 flash memory, and two new locations to optionally add more memory. The Teensy 4.1 has the same size and shape as the Teensy 3.6 (2.4in x 0.7in) and provides greater I/O capacity, including an Ethernet PHY, an SD card jack, and a USB host port. When running at 600 MHz, the Teensy 4.1 consumes approximately 100 mA of current and provides support for the dynamic scale of the clock. Unlike traditional microcontrollers, where changing clock speed causes incorrect baud rates and other problems, Teensy 4.1 hardware and Teensyduino software support for Arduino synchronization functions are designed to allow dynamically speed changes. Serial baud rates, audio stream sample rates, and Arduino functions like delay() and millis(), and Teensyduino extensions like IntervalTimer and elapsedMillis, continue to function properly as the CPU changes speed. Teensy 4.1 also provides a power shutdown function. By connecting a button to the ON/OFF pin, the 3.3V power supply can be completely disabled by holding the button for five seconds and back on with a short press button. If a coin cell is connected to VBAT, the Teensy 4.1 RTC also keeps track of the date and time while the power is off. Teensy 4.1 can also be overclocked, far beyond 600 MHz! The ARM Cortex-M7 brings many powerful CPU functions to a true real-time microcontroller platform. The Cortex-M7 is a dual-emission processor, meaning the M7 can execute two instructions per clock cycle, at 600 MHz. Of course, running two simultaneously depends on compiler order instructions and logs. Initial parameters have shown that the C++ code compiled by Arduino tends to achieve two instructions approximately 40% to 50% of the time while performing intensive numerical work using integers and pointers.
