Teensy 4.0

DEV-15583

Teensy 4.0 is the latest Teensy, offering the fastest microcontroller and powerful peripherals in the

Teensy 1.4 by 0.7 inch form factor. It features an ARM Cortex-M7 processor at 600MHz, with a NXP

iMXRT1062 chip, the fastest microcontroller available today. Teensy 4.0 is the same size and shape

as Teensy 3.2, and retains compatibility with most of the pin functions on Teensy 3.2.

When running at 600 MHz, Teensy 4.0 consumes approximately 100mA current. Teensy 4.0

provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the

clock speed causes wrong baud rates and other issues, Teensy 4.0 hardware and Teensyduino's

software support for Arduino timing functions are designed to allow dynamically speed changes.

Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and millis(), and

Teensyduino's extensions like IntervalTimer and elapsedMillis, continue to work properly while the

CPU changes speed. Teensy 4.0 also provides a power shut off feature. By connecting a pushbutton

to the On/Off pin, the 3.3V power supply can be completely disabled by holding the button for 5

seconds, and turned back on by a brief button press. If a coin cell is connected to VBAT, Teensy

4.0's RTC also continues to keep track of date & time while the power is off. Teensy 4.0 also can

also be overclocked, well beyond 600MHz!
