STM32G0系列出现在CubeMX里，大家有没有简介资料？

styleno1

Added the support of the STM32G0 Series: STM32G081xx, STM32G071xx, and
STM32G070xx

内核是哪个呢，难道是Cortex-M23？

难道这就是一年前泄露的新的M0系列？

之前网友说的是M23，看来不是这个型号，这个是M0+系列.

配套了NUCLEO，DISCO和EVAL板子。

很久以前在网友贴出来的。

M23是STM32L5，G0是M0+，据说会比现有的L0要便宜10%，我看了一些集成了PD，但没有USB。





之前数据手册没出来，ST发邮件要求购买开发工具，已知现在准备好的工具有2套，没看到资料，管它，先下单买个十来套Nucleo再说，反正迟早都是要卖的。
-       NUCLEO-G071RB : Now available in volume for any shipment.
-       RRP 10.32$

-       STM32G081B-EVAL: Confirmed ready for first shipments on W48
-       RRP:  382$

PD的特性

USB Type-C™ Power Delivery controller
The device embeds two controllers (UCPD1 and UCPD2) compliant with USB Type-C Rev.
1.2 and USB Power Delivery Rev. 3.0 specifications.
The controllers use specific I/Os supporting the USB Type-C and USB Power Delivery
requirements, featuring:
• USB Type-C pull-up (Rp, all values) and pull-down (Rd) resistors
• “Dead battery” support
• USB Power Delivery message transmission and reception
• FRS (fast role swap) support
The digital controller handles notably:
• USB Type-C level detection with de-bounce, generating interrupts
• FRS detection, generating an interrupt
• byte-level interface for USB Power Delivery payload, generating interrupts (DMA
compatible)
• USB Power Delivery timing dividers (including a clock pre-scaler)
• CRC generation/checking
• 4b5b encode/decode
• ordered sets (with a programmable ordered set mask at receive)
• frequency recovery in receiver during preamble
The interface offers low-power operation compatible with Stop mode, maintaining the
capacity to detect incoming USB Power Delivery messages and FRS signaling

拿来做过快充倒是不错，值得改改我的尼康相机的电池充电器，出门少带一个插座一根线了，省了STUSB45000/STUSB1602这些花钱的货。

哦，记错了，M33 核的STM32L5已经发布了，官网可以下载到数据手册。那M23我应该是没听过。

什么时候能放出G0的手册？

Anne

拉到56MHz，12位的ADC可以0.4uS，还带DAC就差5V供电了
