Teensy 4.1 is old now

Paul Stoffregen is looking forward for his successor , but nothing is sure for now.
At first they spoke of the iMX RT1170 as successor , but now he say :

Quote We decided to skip RT1170 and wait for NXP's next generation RT chip.

And if Paul get more information , we will not be able to get any information because :

Quote PJRC signed a NDA with NXP, so if I knew anything about NXP's future plans I wouldn't be able to discuss details that aren't yet on their public website.

But one is sure ... MMBasic on a teensy will probably be the most powerful of all

voila

Theory is when we know everything but nothing work ...
Practice is when everything work but no one know why ;)

I have a few Teensy 4.1's and I really like them. Great USB support, but the best bit is the 600Mhz processor. I have one running some quite complex flame calculations.

But I do struggle to find a use for them in most projects because of the price. But if you need raw processing speed - then these are the best I've found so far.

I have been mulling over using one as a network hub for multiple CMM2's. So, it would provide a central storage unit (SD Card), internet access and shared memory that could be accessed via RS-232/Com. Sort of like a mini-mainframe. I did even think about shunting some of the processing onto the Teensy - but the CMM2 is so fast, that I don't think there would be a huge advantage - besides, with this setup you could shunt some of the processing off to other CMM2s.

So this would either be for a small multi-processor computer or a distributed network (like Mainframe terminals, except the bulk of the processing would be done on the terminals).

Pete,

Is the teensy 4.1 more powerfull than the STM32H743 on CMM2 ?
The clock speed is not that much higher (600 vs 500MHz).
It feels they are all in the same ballpark (Teensy, Beaglebone, STM32H series).

Oops, the AM3358 on the Beaglebone the leader of the pack (DMIPS).

Quote The successor to NXP's RT1170 is expected to be the **i.MX RT1180**.

## Key Features of the i.MX RT1180

The i.MX RT1180 continues the lineage of the RT series, offering a blend of high-performance and efficiency. Here are some of its highlights:

### Performance
- Dual-core architecture with an Arm Cortex-M7 core capable of running at up to **1 GHz**, alongside a Cortex-M4 core.
- Enhanced memory interfaces, including support for both SDRAM and NAND Flash.

### Connectivity
- The i.MX RT1180 integrates multiple **Ethernet interfaces** (supporting TSN and AVB), which is essential for industrial applications.
- Offers various connectivity options including USB, CAN, and more.

### Advanced Features
- Advanced security features such as secure boot, hardware crypto engines, and support for NXP's EdgeLock Assurance program.
- Enhanced graphical capabilities suitable for sophisticated user interfaces and displays.

### Development Ecosystem
- Fully supported by the MCUXpresso ecosystem, which facilitates rapid development with easy access to SDKs, IDEs, and configuration tools.

This innovative development marks NXP's intention to offer more advanced and versatile solutions in the wake of the RT1170's success in the market.

The i.MX RT1180 addresses a range of applications, including industrial automation, IoT devices, and smart home technologies, making it a robust successor to the RT1170.

Sorry, I can't give a definitive answer to that, because I'm coding the Teensy in compiled C and the CMM2 in interpreted BASIC. So, the compiled C is always going to be significantly faster.

Having said that, the CMM2 is so fast, that I don't feel that it's lacking in any power. And an extra 20% speed boost in processing might not make a significant difference to games etc.

If you're asking if I feel MMBasic would be significantly better on the the Teensy 4.1, then my answer would probably be no. There have been supply issues with the Teensy in the past (it's not open source), and I know there is an ongoing dispute with AdaFruit over it.

The i.MX RT1180 is available in a 144 ball MAPBGA package. (And bigger ones.) How many layers do you need to break that out?

Memory does not look expansive, so RAM and Flash would be needed.
Runs on 3V3 with internal 1V8 regulator and other lower voltages. Max current is 1 Amp!

It's available now at Digikey.

So a custom board is not out of the question, but it doesn't seem worth it to me. Not when, say, an entire Pi Zero 2 is cheaper than just the RT1180 and easier to get.
