The Teensy 4.1 is the newest iteration of the astoundingly popular development platform that features an ARM Cortex-M7 processor at 600MHz, with an NXP iMXRT1062 chip, four times larger flash memory than the 4.0, and two new locations to optionally add more memory. 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.

When running at 600 MHz, the Teensy 4.1 consumes approximately 100mA current and provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.1 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 4.1 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 five seconds and turned back on by a brief button press. 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. Teensy 4.1 also can also be overclocked, well beyond 600MHz!

Teensy 4.1’s Cortex-M7 processor includes a floating-point unit (FPU) that supports both 64 bit “double” and 32-bit “float”. With M4’s FPU on Teensy 3.5 & 3.6, and also Atmel SAMD51 chips, only 32-bit float is hardware accelerated. Any use of double, double functions like log(), sin(), cos() means slow software implemented math. Teensy 4.1 executes all of these with FPU hardware.

1 x Teensy 4.1 Development Board

For TI''s newest low power, fixed-and-floating point DSP look at TMDSC674x DSPs and the TMDSLCDK6748 development kit.

The TMS320C6713 DSP Starter Kit (DSK) developed jointly with Spectrum Digital is a low-cost development platform designed to speed the development of high precision applications based on TI´s TMS320C6000 floating point DSP generation. The kit uses USB communications for true plug-and-play functionality.  Both experienced and novice designers can get started immediately with innovative product designs with the DSK´s full featured Code Composer Studio™ IDE and eXpressDSP™ Software which includes DSP/BIOS and Reference Frameworks.

The C6713 DSK tools  includes the latest fast simulators from TI and  access to the Analysis Toolkit via Update Advisor which  features the Cache Analysis tool and Multi-Event Profiler. Using Cache Analysis developers improve the performance of their application by optimizing cache usage. By providing a graphical view of the on-chip cache activity over time the user can quickly determine if their code is using the on-chip cache to get peak performance. 

The C6713 DSK allows you to download and step through code quickly and uses Real Time Data Exchange (RTDX™) for improved Host and Target communications. The DSK includes the Fast Run Time Support libraries and utilities such as Flashburn to program flash, Update Advisor to download tools, utilities and software and a power on self test and diagnostic utility to ensure the DSK is operating correctly.

The full contents of the kit include:

• C6713 DSP Development Board with 512K Flash and 16MB SDRAM
• C6713 DSK Code Composer Studio™ IDE including the Fast Simulators and access to Analysis Toolkit on Update Advisor
• Quick Start Guide
• Technical Reference
• Customer Support Guide
• USB Cable
• Universal Power Supply
• AC Power Cord(s)
• MATLAB from The Mathworks 30 day free evaluation

Ordering Information: TMDSDSK6713 includes a standard US power cord, TMDSDSK6713-0E version includes both UK & European power cords

Features

The DSK features the TMS320C6713 DSP, a 225 MHz device delivering up to 1800 million instructions per second (MIPs) and 1350 MFLOPS.  This DSP generation is designed for applications that require high precision accuracy. The C6713 is based on the  TMS320C6000 DSP platform designed to needs of high-performing high-precision applications such as pro-audio, medical and diagnostic. Other hardware features of the TMS320C6713 DSK board include:

• Embedded JTAG support via USB
• High-quality 24-bit stereo codec
• Four 3.5mm audio jacks for microphone, line in, speaker and line out
