Pin Change Interrupts All digital pins can detect changes. The pinMode function with INPUT_PULLUP or INPUT_PULLDOWN must be used toĬonfigure these pins to input mode with the built-in resistor. These are used to keep the pin at logic HIGH or logic LOW or the sameĪctively driven by external circuity. Input Pullup / Pulldown / Keeper Resistors All digital pins have optional pullup, pulldown, or keeper resistors. This pinout reference card comes with Teensy 4.1.Ĭards printed before September 2021 incorrectly showed pin 53 with PWM.Ī larger, more detailed pinout chart by KurtE is also available on the forum.ĭigital Pins Digital Input Pins Digital pins Teensy 4.1 has a total of 55 input/output signal pins. Digital Signal Processing DSP extension instructions accelerate signal processing,Īutomatically makes uses of these DSP instructions. With M7, after a loop has executed a few times, the branch prediction removes that overhead, allowing the branch instruction to run in only a single clock cycle.

On Cortex-M4 & earlier, loops and other code which much branch take 3 clock cycles. Cache Two 32K caches, one for instructions and one for data, are used to speedīranch Prediction Cortex-M7 is the first ARM microcontroller to use branch prediction. These extremely high speedīuses are separate from M7's main AXI bus, which accesses other memory and peripherals. Perform up to 2 separate memory accesses in the same cycle.

The DTCM bus is actually a pair of 32 bit paths, allowing M7 to

The ITCM bus provides a 64 bit path toįetch instructions. Tightly Coupled Memory Tightly Coupled Memory is a special feature which allows Cortex-M7 fast single cycleĪccess to memory using a pair of 64 bit wide buses. 64 bitĭouble precision runs at half the speed of 32 bit float. Floating Point Unit The FPU performs 32 bit float and 64 bit double precision math in hardware.ģ2 bit float speed is approximately the same speed as integer math. Numerically intensive work using integers and pointers. Initial benchmarks have shown C++ code compiled byĪrduino tends to achieve 2 instructions about 40% to 50% of the time while performing Per clock cycle, at 600 MHz! Of course, executing 2 simultaneously depends upon the compiler Dual Issue Superscaler Architecture Cortex-M7 is a dual-issue superscaler processor, meaning M7 can execute 2 instructions CPU performance is many times faster than typical 32 bit microcontrollers.
