Processor:
- Performance: ARM Cortex-M7 offers high-speed real-time computing.
- Dual-Issue Superscalar Architecture: Executes 2 instructions per clock at 600 MHz depending on compiler optimization.
- Floating Point Unit: 32-bit float matches integer speed; 64-bit double runs at half speed.
- Tightly Coupled Memory: Single-cycle access to memory via ITCM & DTCM buses.
- Cache: Two 32K caches for instructions and data.
- Branch Prediction: Reduces loop and branch overhead.
- Digital Signal Processing: DSP instructions accelerate signal processing and Fourier transform.
Pinouts:
Teensy 4.1 brings all general-purpose I/O pins to breadboard-friendly pads, with a total of 55 I/O pins. 42 are accessible using a solderless breadboard. A pinout reference card is included (front/back).
