 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

With a higher core clock speed, twice the memory, more powerful Arm cores, new security features, and upgraded interfacing capabilities, Pico 2 delivers a significant performance and feature uplift, while retaining hardware and software compatibility with earlier members of the Pico series. Dual Arm Cortex-M33 with floating point and DSP support or dual Hazard3 processors @ 150MHz 520 KB on-chip SRAM Software- and hardware-compatible with Raspberry Pi Pico 1 Drag-and-drop programming using mass storage over USB Castellated module allows soldering direct to carrier boards Robust and fully documented security features: Optional boot signing, enforced by on-chip mask ROM, with key fingerprint in OTP Protected OTP storage for optional boot decryption key Global bus filtering based on Arm or RISC-V security/privilege levels Peripherals, GPIOs, and DMA channels individually assignable to security domains Hardware mitigations for fault injection attacks Hardware SHA-256 accelerator 2 × UART 2 × SPI controllers 2 × I2C controllers 24 × PWM channels 4 x ADC channels 1 × USB 1.1 controller and PHY, with host and device support 12 × upgraded PIO state machines A new HSTX peripheral for high-speed data transmission Support for external QSPI PSRAM Open source C/C++ SDK, MicroPython support Operating temperature -20°C to +85°C Supported input voltage 1.8–5.5V DC 12 PI0s!! And yes the AtoD now works as advertised :-) Regards Kevin Edited 2024-08-09 01:47 by Bleep |

Micro USB still  I wonder about overclockability....Kinda like my 378MHz  |

Only one way to find out. RP2350 will be generally available in volume before the end of 2024. To register your interest, and to participate in our samples program, head over to the product page. product page |

Oh wow, I've just realised that the chip has both 2 by M33 Cortex AND 2 by RISC-V processors swappable at boot time, implement by Luke Wren, one of the engineers at Pi in his spare time! Luke's posts on X throughout the development. "thanks to a bonus feature of RP2350: a pair of open-hardware Hazard3 RISC-V cores which can be substituted at boot time. All features of the chip, apart from a handful of security features, and the double-precision floating-point accelerator, are available in RISC-V mode." Could be very interesting.

12 pio state machines, not 12 PIO's. The rp2040 has 8 When the M33 arm cores are code compatble with the current M0 cores, there is a chance a mmbasic port is possible. The RAM is welcome, however, Peter tweaked the hell out of the current 264k. I wonder if he is ever going this path again. He must have grown grey hair from pico.. Volhout Risk V ? It is either arm or riskV. I think the riskV cores are mpre a political statement then anythin else. Edited 2024-08-09 02:39 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi Harm, Still a very respectable increase of "PIO state machines", though I note still the same number of instructions, 32, shared between each 4 state machines. Yes I think you are correct about the RISC-V, but I'm sure someone will want to use them, other than for dev work. Yes hopefully Peter will be able to produce a new variant, double the ram and flash, along with hardware float might be a help. If not I'm still very happy with my Picomites. :-) Still in daily use. Regards Kevin. |

 It seems to have double precision floating point hardware support in addition the the extra RAM. Also, The new RP2350 will be available in a 80 pin version with 48 GPIO -Carl |

<Rant>WOW, Just Great! GUESS MY ENTIRE INVENTORY OF 2040 PICOS ARE USELESS JUNK. in a few months there will be no one updating projects or creating new projects, it's like Who Maintains projects for the RCA CDP1802? yeah sure there are some Elf Weirdos but it took 50 years to become Kitschy Cool enough for a few NutJobs to spend $100 on a 50 year old $25 chip ! I how I sound like a Kook, but think about it in 1980 44 years ago, the Cray1 was enough Power/Memory & Storage, to Design & Execute the annihilation of your entire Species and Planet. the 2040 Pico has an order of Magnitude of more power for $5.00! why do we need as new CPU ? I don't understand how your Species will Advance if you're going too get 3-4 years invested in an architecture, then Give up and Start Over! This isn't just a joke Post. I Have a Real anxiety about this, I've invested way too Much money and I'm Just Starting to Learn enough to make them Useful, and now POOF, we're yanking the rug out! Like the CMM2 I was Late to the Party, but thankfully I was lucky enough to acquire 2 of them from some Great members, and I loved my CMM2s but since the chip shortage, Development has Stoped. My Favorite Vidiot Game (Gauntlet) was Ported to the CMM, But only 1/2 of Wolfinstein and NO Doom or Quake! I would BUY the Doom engine Port! </Rant> I may be Vulgar, but , while I'm poor, I'm Industrious, Honest, and trustworthy! I Know my Place |

There is no MMBasic port for the RP2350 and there may never be. We don't know if it will overclock and at 150MHz will be slower than the 378MHz RP2040. The double precision H/W is only partial. Don't throw your RP2040s yet  |

I am not sure the pico2 will be better at anything, except for the RAM. The pico2 boards will have thr rp2350A, that has 30 IO pins. Same as 2040. The 2350 does not support the single cycle IO insruction. This may impact i.e. the PORT command The rp2350 has lower interrupt latency, but if you cant overclock it the 2040 is faster. Also the longer pipelin (3 vs 2) does not help. The floating point support is single precision, 32x32=32. So it helps, but it is not double precision. I did not read the datasheet, but can imagine that the 30 IO pin chip only has 8 state machines in 2 PIOs. Additional. When the M33 cannot be overclocked as well VGA using a 252Mhz core on the 2040, is not possible. Volhout PicomiteVGA PETSCII ROBOTS |

This article: https://dmitry.gr/?r=06.+Thoughts&proj=11.+RP2350 Suggests overclocking to 300Mhz is no problem for the new chip. The RP2350 chip (Not the Pi Pico 2 module) also supports QSPI PSRAM in addition to QSPI flash memory. The Cortex M33 cores used in the RP2350 also have partial support for Double Precision floating point maths in addition to the single precision optionally available on the M33 core. Details are still coming in, but a PicoMiteII with the 520K, 48 I/O RP2350B and optional PSRAM would be amazing and still at a very low price point! -Carl |

It looks like double-precision is 2-3 cycles per operation! Oh, and I/O pins that are officially 5V tolerant??? It just keeps looking better and better Edited 2024-08-09 06:29 by Sasquatch -Carl |

I ordered 2 but there's an option to cancel a preorder if mmbasic will not be supporting it |

OK I Sincerely Apologize I just watched Jeff Greeling's Video about the Pico 2,and all my concerns were unfounded. Again I Apologize for being reactionary. Edited 2024-08-09 09:03 by Rickard5 I may be Vulgar, but , while I'm poor, I'm Industrious, Honest, and trustworthy! I Know my Place |
